Description

Technical Field

[0001] This invention relates to the field of high-voltage switchgear and power distribution control technology, and more specifically, to an integrated pole-mounted switchgear system with visible break points and its collaborative control method. Background Technology

[0002] Pole-mounted switches are important switching devices used in power distribution lines for line opening and closing, fault isolation, and maintenance operations. To ensure electrical isolation safety after opening, pole-mounted switches are typically equipped with isolating stationary contacts and isolating moving contacts. An operating mechanism moves the isolating moving contact away from the isolating stationary contact, creating an isolation gap between them. Some pole-mounted switches also have observation windows or mechanical indicating structures to confirm the isolation opening status from outside the equipment.

[0003] However, existing pole-mounted switches typically determine whether the isolation action is complete based on the operating shaft rotation angle, transmission mechanism stroke, the theoretical opening position of the isolating moving contact, or fixed mechanical limits. This method relies on a stable positional correspondence between the operating mechanism, transmission mechanism, and isolating contact. However, during long-term operation, factors such as isolating stationary contact support misalignment, contact wear, increased transmission clearance, mechanism idle stroke, or isolating moving contact jamming can all cause changes in this positional correspondence. Therefore, even if the operating mechanism reaches the theoretical opening position, the actual physical break space formed between the isolating stationary contact and the isolating moving contact may still deviate from the original design state.

[0004] Based on this, existing visible break structures usually determine whether a break has been formed based on the operating position of the isolation mechanism, the mechanical indication status, or the externally visible opening form. The above judgment mainly reflects the operating status of the mechanism and is difficult to directly reflect the actual physical break space formed between the isolation stationary contact and the isolation moving contact.

[0005] Therefore, when the position of the isolating contact changes or the transmission relationship deviates, the existing pole-mounted switch may exhibit a discrepancy between the mechanism's open state and the externally visible state and the actual break formation. This makes it difficult to accurately confirm the actual physical break space formed between the isolating stationary contact and the isolating moving contact, thus affecting the reliability of the isolation state judgment. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art and to achieve the above objectives, the present invention provides the following technical solution: an integrated pole-mounted switch system with visible break points, comprising:

[0007] The fracture observation reference module, within the enclosed housing of the pole-mounted switch, forms a fracture observation reference corresponding to the external observation position based on the area where the isolating stationary contact is located, the complete opening target area of ​​the isolating moving contact, and the physical fracture space between the two.

[0008] The main circuit interruption coordination module executes the interruption and arc extinguishing of the main circuit based on the main circuit interruption request, and generates isolation action release conditions according to the completion status of the main circuit interruption and arc extinguishing.

[0009] The dual-reference fracture forming module establishes a fracture forming reference based on the actual positions of the isolating stationary contact and the isolating moving contact. Based on the isolating action release condition, it performs the separation of the isolating moving contact relative to the isolating stationary contact, dividing the separation process into a fracture forming stage and a fracture exposure stage. According to the fracture forming reference, it controls the isolating moving contact to enter the fracture exposure stage after the fracture forming stage is completed, forming a fracture exposure completed state.

[0010] The fracture space verification interlocking module, based on the fracture exposure completion state, forms a temporary verification channel jointly defined by the isolation stationary contact and the isolation moving contact according to their actual positions. The solid fracture space between the isolation stationary contact and the isolation moving contact is verified by the insulation verification component through the temporary verification channel. Based on the verification results, a safe isolation interlocking allowable state and a complete fracture observation state based on the fracture observation benchmark are formed.

[0011] In a preferred embodiment of the present invention, the process of forming a fracture observation reference corresponding to an external observation position based on the area where the isolation stationary contact is located, the complete opening target area of ​​the isolation moving contact, and the physical fracture space between the two includes:

[0012] Within the enclosed housing of the pole-mounted switch, the area where the isolating stationary contact is located is formed according to the actual installation position and contact outline of the isolating stationary contact. The complete opening target area of ​​the isolating moving contact is formed according to the separation direction of the isolating moving contact relative to the isolating stationary contact, the complete opening position, and the contact outline.

[0013] Between the area where the isolating stationary contact is located and the target area where the isolating moving contact is fully tripped, the separation direction of the isolating moving contact relative to the isolating stationary contact is taken as the extension direction. A continuous observation section is formed by passing through the solid break space along the extension direction. An observation path leading to the external observation position is formed based on the continuous observation section. A break observation reference corresponding to the external observation position is formed according to the observation path.

[0014] In a preferred embodiment of the present invention, the process of executing the main circuit interruption and arc extinguishing based on the main circuit interruption request, and generating isolation action release conditions according to the completion status of the main circuit interruption and arc extinguishing, includes:

[0015] Based on the main circuit breaking request, the main circuit breaking mechanism is driven to break the main circuit contacts, and the arc generated during the breaking process is introduced into the arc extinguishing mechanism for arc extinguishing, thus forming the main circuit breaking and arc extinguishing completed state.

[0016] Based on the main circuit opening and arc extinguishing completion status, the control isolation interlock mechanism releases the interlock restriction on the isolation transmission mechanism, forming an isolation interlock release state, and generates isolation action release conditions based on the isolation interlock release state.

[0017] In a preferred embodiment of the present invention, the process of establishing a fracture forming reference based on the actual positions of the isolating stationary contact and the isolating moving contact includes:

[0018] The actual positions of the isolating stationary contact and the isolating moving contact are used as the stationary contact position reference and the moving contact position reference, respectively. The relative spatial position relationship between the isolating stationary contact and the isolating moving contact is formed based on the stationary contact position reference and the moving contact position reference.

[0019] Using the separation direction of the isolating moving contact relative to the isolating stationary contact as the directional reference, a fracture spatial relationship jointly defined by the actual positions of the isolating stationary contact and the isolating moving contact is established based on the relative spatial position relationship. The fracture spatial relationship is used as the spatial constraint basis for the separation process of the isolating moving contact, and a fracture forming reference is established.

[0020] In a preferred embodiment of the present invention, the process of separating the isolation moving contact relative to the isolation stationary contact based on the isolation action release condition, and dividing the separation process into a fracture formation stage and a fracture exposure stage, includes:

[0021] Based on the isolation action release condition, the isolation moving contact is driven to move along the separation direction relative to the isolation stationary contact, forming a continuous separation stroke of the isolation moving contact. During the continuous separation stroke, the stage transition position is defined according to the fracture forming reference. The stroke between the starting position of the continuous separation stroke and the stage transition position is taken as the first motion range, and the stroke between the stage transition position and the fully open position of the isolation moving contact is taken as the second motion range.

[0022] The separation process of the isolating moving contact relative to the isolating stationary contact in the first motion range is divided into the fracture formation stage, and the process of the isolating moving contact continuing to move towards the complete opening position of the isolating moving contact in the second motion range is divided into the fracture exposure stage.

[0023] In a preferred embodiment of the present invention, the process of controlling the isolation moving contact to enter the fracture exposure stage after the fracture formation stage, based on the fracture forming criterion, to form a fracture exposure completed state includes:

[0024] Based on the fracture forming criterion, the motion state of the isolating moving contact at the stage transition position is defined, forming a stage transition relationship for the isolating moving contact from the first motion range to the second motion range;

[0025] Based on the phase transition relationship, a motion connection relationship is established between the first motion interval and the second motion interval. Based on the motion connection relationship, a break exposure stroke extending from the phase transition position to the complete opening position of the isolating moving contact is formed. According to the actual position formed by the isolating moving contact along the break exposure stroke, the break exposure completion state of the isolating moving contact entering the complete opening target area is formed.

[0026] In a preferred embodiment of the present invention, the process of forming a temporary verification channel jointly defined by the isolation stationary contact and the isolation moving contact based on the completed fracture exposure state includes:

[0027] Based on the completed state of the fracture exposure, and according to the actual positions of the isolating stationary contact and the isolating moving contact, a first verification boundary corresponding to the isolating stationary contact and a second verification boundary corresponding to the isolating moving contact are formed respectively. Based on the relative positions between the first verification boundary and the second verification boundary, the spatial range between the two verification boundaries is defined, forming a verification space jointly defined by the first verification boundary and the second verification boundary.

[0028] Using the direction of travel of the insulation verification component as the direction of channel extension, a continuous temporary verification channel is formed in the verification space along the direction of channel extension.

[0029] In a preferred embodiment of the present invention, the process of verifying the physical break space between the isolating stationary contact and the isolating moving contact by using an insulating verification component to verify the passage state of the temporary verification channel includes:

[0030] Based on the temporary verification channel, the driven insulation verification component travels along the channel extension direction within the verification space. According to the actual passage result of the insulation verification component between the first verification boundary and the second verification boundary, a passage passing state or a passage blocked state is formed. Based on the passage passing state, a verification passing result of the actual break space is formed, and based on the passage blocked state, a verification failing result of the actual break space is formed.

[0031] In a preferred embodiment of the present invention, the process of forming a safety isolation interlocking permissible state and a complete fracture observation state based on the fracture observation benchmark according to the verification results includes:

[0032] Based on the verification results of the physical break space and the isolation interlock release status, establish the interlock correspondence between the verification results and the isolation interlock release status, and form a safety isolation interlock permission status according to the interlock correspondence.

[0033] Based on the completed state of fracture exposure and the fracture observation benchmark, establish the observation correspondence between the physical fracture space and the external observation position along the observation path to form the fracture exposure observation state. Establish the fracture verification correspondence between the verification pass result and the fracture exposure observation state, and form the complete fracture observation state based on the fracture verification correspondence.

[0034] As a preferred embodiment of the present invention, the collaborative control method for an integrated pole-mounted switch system with visible break points includes the following steps:

[0035] S1: Within the enclosed housing of the pole-mounted switch, a break observation reference corresponding to the external observation position is formed based on the area where the stationary isolating contact is located, the complete opening target area of ​​the moving isolating contact, and the physical break space between the two.

[0036] S2: Based on the main circuit interruption request, execute the main circuit interruption and arc extinguishing, and generate isolation action release conditions according to the completion status of the main circuit interruption and arc extinguishing;

[0037] S3: Establish the fracture forming reference based on the actual positions of the isolating stationary contact and the isolating moving contact. Based on the isolating action release condition, separate the isolating moving contact from the isolating stationary contact. Divide the separation process into the fracture forming stage and the fracture exposure stage. According to the fracture forming reference, control the isolating moving contact to enter the fracture exposure stage after the fracture forming stage is completed, and form the fracture exposure completed state.

[0038] S4: Based on the completed state of the fracture exposure, a temporary verification channel is formed by the actual positions of the isolating stationary contact and the isolating moving contact. The physical fracture space between the isolating stationary contact and the isolating moving contact is verified by the insulation verification component through the temporary verification channel. Based on the verification results, a safety isolation interlocking allowable state and a complete fracture observation state based on the fracture observation benchmark are formed.

[0039] Compared with the prior art, the advantages of the present invention are as follows: The present invention solves the problem that the existing pole-mounted switch cannot accurately reflect the physical break space when the position of the isolating contact changes or the transmission relationship deviates. This is achieved through the collaborative processing flow of establishing the break observation benchmark, coordinating the main circuit opening, forming the dual benchmark break, and checking and interlocking the break space.

[0040] At the level of fracture formation and observation, a fracture observation benchmark corresponding to the external observation position is established based on the area where the isolating stationary contact is located, the complete opening target area of ​​the isolating moving contact, and the physical fracture space. This gives the external observation a basis corresponding to the actual contact position and the physical fracture space. After the main circuit is interrupted and the arc is extinguished, the isolation action release condition is generated to achieve sequential connection with subsequent isolation actions. At the same time, a fracture forming benchmark is established based on the actual positions of the isolating stationary contact and the isolating moving contact. Based on this, the fracture formation stage and the fracture exposure stage are divided and connected, reducing the influence of deviation caused by relying on the theoretical position of the mechanism to judge the fracture formation process.

[0041] At the level of physical break verification, a temporary verification channel is formed based on the complete state of break exposure and the actual position of the two contacts. The verification pass result or verification failure result of the physical break space is obtained through the physical passage result of the insulation verification component. The verification pass result is then correlated with the isolation interlock release state and the break exposure observation state to form the safety isolation interlock allow state and the complete break observation state.

[0042] In summary, this invention relies on the collaborative processing of fracture observation benchmark, dual-benchmark fracture forming, and solid space passage verification, so that the isolation state judgment is more based on the actual position of the two contacts and the actual solid fracture space formed. This helps to reduce the inconsistency between the mechanism's opening state, the externally visible state, and the actual fracture formation, and improves the reliability of the isolation state judgment.

[0044] Figure 2 This is a flowchart illustrating the steps of the collaborative control method for the integrated pole-mounted switch system with visible interruption ports according to the present invention. Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0046] Example 1: As Figure 1 As shown, the integrated pole-mounted switch system with visible break points proposed in this invention includes:

[0047] The fracture observation reference module, within the enclosed housing of the pole-mounted switch, forms a fracture observation reference corresponding to the external observation position based on the area where the isolating stationary contact is located, the complete opening target area of ​​the isolating moving contact, and the physical fracture space between the two.

[0048] The process of forming a fracture observation reference corresponding to the external observation position, based on the area where the isolation stationary contact is located, the complete opening target area of ​​the isolation moving contact, and the physical fracture space between the two, includes:

[0049] Within the enclosed housing of the pole-mounted switch, the area where the isolating stationary contact is located is formed according to the actual installation position and contact outline of the isolating stationary contact. The complete opening target area of ​​the isolating moving contact is formed according to the separation direction of the isolating moving contact relative to the isolating stationary contact, the complete opening position, and the contact outline.

[0050] Between the area where the isolating stationary contact is located and the target area where the isolating moving contact is fully open, the separation direction of the isolating moving contact relative to the isolating stationary contact is taken as the extension direction. A continuous observation section is formed by passing through the solid break space along the extension direction. An observation path leading to the external observation position is formed based on the continuous observation section. A break observation reference corresponding to the external observation position is formed based on the observation path.

[0051] The solid fracture space refers to the actual spatial interval area formed between the two contacts after the isolating moving contact and the isolating stationary contact are separated. The position and extent of this area change with the actual position of the two contacts. The external observation position refers to the position located outside the enclosed shell, where the internal isolation fracture can be viewed through the observation window or corresponding observation structure. The fracture observation reference refers to the fixed observation correspondence formed between the external observation position, the observation path, and the internal fracture area that can be observed from the external observation position, which is used to subsequently view the solid fracture space according to the same observation relationship.

[0052] A unified spatial coordinate system is established within the enclosed housing of the pole-mounted switch. The fixed mounting reference surface within the enclosed housing is used as the coordinate positioning basis. A fixed reference point is selected on the mounting reference surface as the origin of the coordinate system, and three fixed directions that are perpendicular to each other along the length, width, and height of the enclosed housing are used as the three coordinate axes. The position and orientation of the isolating stationary contact, isolating moving contact, complete open position, external observation position, and subsequent spatial areas are all represented by this spatial coordinate system.

[0053] The formation process of the area where the isolating stationary contact is located is as follows:

[0054] Laser displacement sensors are set at three different measurement positions around the isolation stationary contact, each facing the outer surface of the isolation stationary contact. Each laser displacement sensor is facing a measurement point on the outer surface of the isolation stationary contact. The three measurement points are fixed on the body of the isolation stationary contact and are not collinear with each other.

[0055] Each laser displacement sensor measures the distance from its measuring end to the corresponding measuring point. Based on the position of each laser displacement sensor mounting base relative to the origin of the spatial coordinate system, the laser emission direction, and the measured distance, the positions of the three measuring points in the spatial coordinate system are obtained.

[0056] Based on the relative positions of the three measuring points on the isolating stationary contact body and the coordinates of the three measuring points in the spatial coordinate system, the actual installation position and actual orientation of the isolating stationary contact in the closed housing of the column switch are obtained.

[0057] Based on the actual installation location and actual orientation, the spatial position of the actual outer contour of the isolating stationary contact within the enclosed housing is obtained. Using the actual outer contour of the isolating stationary contact at this spatial position as the boundary, the actual outer contour and the internal space enclosed by the actual outer contour are defined as the spatial range actually occupied by the isolating stationary contact within the enclosed housing. This spatial range constitutes the area where the isolating stationary contact is located.

[0058] The process of forming the complete tripping target area of ​​the isolating moving contact is as follows:

[0059] An absolute rotary encoder is installed at the rotating shaft that drives the isolating moving contact. The angle values ​​output by the absolute rotary encoder are read when the isolating moving contact is in the separation start position and the full opening position, respectively. The difference between the angle value corresponding to the full opening position and the angle value corresponding to the separation start position is taken as the actual rotation angle of the isolating moving contact from the separation start position to the full opening position.

[0060] Based on the actual rotation angle, the position of the shaft center in the spatial coordinate system, and the distance of each part of the isolating moving contact relative to the shaft center, the spatial position and actual orientation of the isolating moving contact in the fully open state are obtained;

[0061] Based on the spatial position and actual orientation of the isolating moving contact in the fully open state, the spatial position of the actual outer contour of the isolating moving contact in the spatial coordinate system is obtained. Taking the actual outer contour of the isolating moving contact at this spatial position as the boundary, the actual outer contour and the internal space enclosed by the actual outer contour are defined as the spatial range occupied by the isolating moving contact in the fully open state. This spatial range constitutes the target area for the complete opening of the isolating moving contact.

[0062] The formation process of the continuous observation section is as follows:

[0063] A continuous space is defined between the area where the isolating stationary contact is located and the target area where the isolating moving contact is fully open, along the separation direction of the isolating moving contact relative to the isolating stationary contact;

[0064] One end of the continuous space is connected to the area where the isolating stationary contact is located, and the other end is connected to the target area where the isolating moving contact is completely opened. The two ends are connected by the solid break space formed after the isolating stationary contact and the isolating moving contact are separated. This continuous space is used as a continuous observation section.

[0065] The formation process of the pathway can be observed as follows:

[0066] The space extends continuously from the continuous observation section toward the external observation position, with one end of the space connected to the continuous observation section and the other end reaching the external observation position. The space between the continuous observation section and the external observation position is not blocked by the internal solid structure of the closed shell. The aforementioned space range extending continuously from the continuous observation section to the external observation position serves as the observation path.

[0067] The process of forming the fracture observation benchmark is as follows:

[0068] Using the external observation position as the starting point, observe from the external observation position along the observation path toward the inside of the closed shell, and take the internal space that can be continuously seen along the observation path as the internal observation area.

[0069] The internal observation area extends to the continuous observation section, covering the physical break space, and extends to the areas where the isolation stationary contacts are located and the complete opening target area of ​​the isolation moving contacts on both sides of the physical break space;

[0070] Establish the correspondence between the external observation position, the observation path, and the aforementioned internal observation area, and use this correspondence as the fracture observation benchmark for subsequent fracture observation.

[0071] The fracture observation benchmark module aims to provide an observation basis corresponding to the actual position of the isolating contact and the physical fracture space for subsequent fracture exposure observation. It forms the area where the isolating stationary contact is located based on the actual installation position and contact outline of the isolating stationary contact, and forms the complete opening target area of ​​the isolating moving contact based on the separation direction, complete opening position, and contact outline of the isolating moving contact, avoiding the use of only the mechanism's operating position or the externally visible opening shape as the observation basis. A continuous observation section is formed along the separation direction between the two areas, traversing the physical fracture space, and an observation path leading to the external observation position is formed based on this continuous observation section, establishing a fracture observation benchmark corresponding to the external observation position, thus providing a clear spatial observation basis for subsequent fracture exposure observation.

[0072] The main circuit interruption coordination module executes the interruption and arc extinguishing of the main circuit based on the main circuit interruption request, and generates isolation action release conditions according to the completion status of the main circuit interruption and arc extinguishing.

[0073] The process of executing the main circuit interruption and arc extinguishing based on the main circuit interruption request, and generating isolation action release conditions based on the completion status of the main circuit interruption and arc extinguishing, includes:

[0074] Based on the main circuit breaking request, the main circuit breaking mechanism is driven to break the main circuit contacts, and the arc generated during the breaking process is introduced into the arc extinguishing mechanism for arc extinguishing, thus forming the main circuit breaking and arc extinguishing completed state.

[0075] Based on the main circuit opening and arc extinguishing completion status, the control isolation interlock mechanism releases the interlock restriction on the isolation transmission mechanism, forming an isolation interlock release state, and generates isolation action release conditions based on the isolation interlock release state;

[0076] The main circuit breaking and arc extinguishing completion state refers to the state where the main circuit breaking mechanism reaches the termination position of the opening movement and triggers the opening position switch, the opening position switch outputs the opening position signal, and the current value of the main circuit detected by the current sensor is zero; the isolation interlocking mechanism is a mechanism that restricts the action of the isolation transmission mechanism when the main circuit has not yet completed breaking and arc extinguishing, and releases the restriction after the main circuit has completed breaking and arc extinguishing; the isolation transmission mechanism is a mechanism that transmits the driving force to the isolation moving contact and drives the isolation moving contact to move relative to the isolation stationary contact after the interlock restriction is released; the isolation interlock release state refers to the state where the isolation interlocking mechanism is in the released position and the release position limit switch outputs the release position signal; the isolation action release condition refers to the state condition corresponding to the isolation transmission mechanism being able to start driving the isolation moving contact to perform the separation action relative to the isolation stationary contact when the isolation interlocking mechanism is in the released position and the release position limit switch outputs the release position signal.

[0077] The process of main circuit interruption and arc extinguishing completion is as follows:

[0078] Upon receiving the request to break the main circuit, the main circuit breaking mechanism begins to operate, causing the main circuit moving contact and the main circuit stationary contact, which were originally in contact with each other, to separate from each other. As the distance between the two contacts gradually increases, the electric arc generated between the two contacts enters the arc extinguishing mechanism corresponding to the main circuit contact, and the arc extinguishing mechanism extinguishes the arc.

[0079] A trip position switch is set at the tripping end position of the main circuit breaking mechanism. When the main circuit breaking mechanism moves to the tripping end position, the trip position switch is triggered and the tripping end signal is output by the tripping position switch. A current sensor is set in the main circuit to detect the main circuit current after the main circuit contacts are separated.

[0080] When the trip position switch outputs a trip signal and the current sensor detects zero current in the main circuit, the main circuit is opened and the arc extinguishing is completed.

[0081] The process by which the isolation interlock is released and the conditions for the release of isolation actions are formed is as follows:

[0082] A release position limit switch is installed in the release position of the isolation interlocking mechanism. When the main circuit has not yet formed the state of opening and arc extinguishing, the isolation interlocking mechanism is kept in the restricted position, and the isolation transmission mechanism is in the interlocking restriction state.

[0083] After the main circuit is interrupted and the arc is extinguished, the isolation interlocking mechanism moves from the restricted position to the released position. When the isolation interlocking mechanism reaches the released position, the released position limit switch is triggered. The released position limit switch outputs a released position signal. The state in which the isolation interlocking mechanism is in the released position and the released position limit switch outputs a released position signal is recorded as the isolation interlocking released state.

[0084] When the isolation interlocking mechanism is in the released position and the release position limit switch outputs a release signal, the isolation action release condition is formed; after the isolation action release condition is formed, the isolation transmission mechanism drives the isolation moving contact to perform a separation action relative to the isolation stationary contact.

[0085] The main circuit breaking coordination module aims to provide a controlled release condition for the subsequent formation of the isolation break. Based on the main circuit breaking request, it drives the main circuit breaking mechanism to perform contact breaking and guides the arc generated during the breaking process into the arc extinguishing mechanism for processing, so as to form the main circuit breaking and arc extinguishing completion state. In this completion state, it controls the isolation interlocking mechanism to release the interlocking restriction on the isolation transmission mechanism, forming the isolation interlock release state, and generates the isolation action release condition accordingly. This ensures that the subsequent separation action of the isolation moving contact is based on the completion of the main circuit breaking and arc extinguishing, avoiding disordered connection between the main circuit breaking process and the isolation break formation process.

[0086] The dual-reference fracture forming module establishes a fracture forming reference based on the actual positions of the isolating stationary contact and the isolating moving contact. Based on the isolating action release condition, it performs the separation of the isolating moving contact relative to the isolating stationary contact, dividing the separation process into a fracture forming stage and a fracture exposure stage. According to the fracture forming reference, it controls the isolating moving contact to enter the fracture exposure stage after the fracture forming stage is completed, forming a fracture exposure completed state.

[0087] The process of establishing a fracture forming datum based on the actual positions of the stationary and moving isolation contacts includes:

[0088] The actual positions of the isolating stationary contact and the isolating moving contact are used as the stationary contact position reference and the moving contact position reference, respectively. The relative spatial position relationship between the isolating stationary contact and the isolating moving contact is formed based on the stationary contact position reference and the moving contact position reference.

[0089] Using the separation direction of the isolating moving contact relative to the isolating stationary contact as the directional reference, a fracture spatial relationship jointly defined by the actual positions of the isolating stationary contact and the isolating moving contact is established based on the relative spatial position relationship. The fracture spatial relationship is used as the spatial constraint basis for the separation process of the isolating moving contact, and a fracture forming reference is established.

[0090] The fracture forming datum refers to the spatial state condition corresponding to the separation of the actual outer contour of the isolating stationary contact towards the isolating moving contact and the separation of the actual outer contour of the isolating moving contact towards the isolating stationary contact, and the formation of a continuous spatial interval between the two actual outer contours.

[0091] The process of forming the stationary contact position reference, the moving contact position reference, and their relative spatial relationship is as follows:

[0092] The positions of the isolating stationary contact and the isolating moving contact are represented by a spatial coordinate system established during the formation of the fracture observation reference. The actual installation position obtained from three measurement points on the outer surface of the isolating stationary contact is taken as the actual position of the isolating stationary contact. Based on the angle value output by the absolute rotary encoder located at the shaft of the isolating moving contact, combined with the position of the shaft center in the spatial coordinate system and the geometric dimensions of the isolating moving contact relative to the shaft center, the actual position of the isolating moving contact during the separation process is obtained. The actual positions of the isolating stationary contact and the isolating moving contact are respectively used as the position references for the stationary contact and the moving contact.

[0093] Using the actual outer contour of the isolating stationary contact facing the isolating moving contact as the stationary position reference, and the actual outer contour of the isolating moving contact facing the isolating stationary contact as the moving position reference, the actual distance between the moving side position reference and the stationary side position reference along the separation direction away from the isolating stationary contact is obtained. The separation direction of the isolating moving contact relative to the isolating stationary contact is taken as the relative direction. The actual distance and the relative direction constitute the relative spatial position relationship between the two contacts.

[0094] The process of establishing the spatial relationship of the fracture surface and the fracture forming datum is as follows:

[0095] Taking the direction of the isolating moving contact away from the isolating stationary contact as the separation direction, based on the relative spatial position relationship of the two contacts, the actual distance between the actual outer contour of the isolating stationary contact facing the isolating moving contact and the actual outer contour of the isolating moving contact facing the isolating stationary contact is obtained along the separation direction, and the spatial relationship of the fracture is formed based on the continuous change of the actual distance when the isolating moving contact moves along the separation direction.

[0096] In the fracture spatial relationship, when the actual outer contour of the isolating moving contact facing the isolating stationary contact is separated from the actual outer contour of the isolating stationary contact facing the isolating moving contact, and a continuous spatial interval is formed between the two actual outer contours for the first time, this spatial state is taken as the fracture forming reference, and the actual position of the isolating moving contact at this time is taken as the stage transition position.

[0097] The process of separating the isolating moving contact relative to the isolating stationary contact based on the isolating action release condition, and dividing the separation process into a fracture formation stage and a fracture exposure stage, includes:

[0098] Based on the isolation action release condition, the isolation moving contact is driven to move along the separation direction relative to the isolation stationary contact, forming a continuous separation stroke of the isolation moving contact. During the continuous separation stroke, the stage transition position is defined according to the fracture forming reference. The stroke between the starting position of the continuous separation stroke and the stage transition position is taken as the first motion range, and the stroke between the stage transition position and the fully open position of the isolation moving contact is taken as the second motion range.

[0099] The process of the isolating moving contact separating from the isolating stationary contact in the first motion range is divided into the fracture formation stage, and the process of the isolating moving contact continuing to move towards the complete opening position of the isolating moving contact in the second motion range is divided into the fracture exposure stage.

[0100] The stage transition position refers to the actual position of the isolating moving contact when the actual spatial state between the isolating moving contact and the isolating stationary contact first meets the fracture forming criterion during the continuous separation stroke of the isolating moving contact. This position also serves as the end position of the first movement interval and the beginning position of the second movement interval.

[0101] The process of continuous separation stroke, stage transition position, and formation of two motion ranges is as follows:

[0102] After the isolation action release condition is formed, the restriction on the separation action of the isolating moving contact is released, and the isolating transmission mechanism drives the isolating moving contact to move continuously in the direction away from the isolating stationary contact; starting from the position where the isolating moving contact begins to separate, it is connected to each position it passes through continuously along the separation direction to the complete opening position, and the continuous movement path formed constitutes the continuous separation stroke.

[0103] Along the continuous separation stroke, the spatial state between the two contacts relative to their actual outer contours is obtained based on the actual positions of the isolating stationary contact and the isolating moving contact. When the spatial state first satisfies the fracture forming criterion, the actual position of the isolating moving contact at this time is taken as the stage transition position. The stroke corresponding to the position where the isolating moving contact begins to separate and the stage transition position is taken as the first motion interval, and the stroke corresponding to the stage transition position and the complete opening position is taken as the second motion interval.

[0104] The process of dividing the fracture formation stage and the fracture exposure stage is as follows:

[0105] Within the first motion range, the isolating moving contact moves from the position where it begins to separate from the isolating stationary contact to the stage transition position. The two contacts gradually change from a contact or adjacent state to a state of forming a continuous spatial gap. The separation process of the isolating moving contact relative to the isolating stationary contact within this range is regarded as the break formation stage.

[0106] Within the second movement interval, the isolating moving contact continues to move from the stage transition position to the complete open position along the separation direction. The movement process of the isolating moving contact between the stage transition position and the complete open position is regarded as the break exposure stage.

[0107] Based on the fracture forming criterion, the process of controlling the isolation moving contact to enter the fracture exposure stage after the fracture forming stage, and forming the fracture exposure completed state, includes:

[0108] Based on the fracture forming criterion, the motion state of the isolating moving contact at the stage transition position is defined, forming a stage transition relationship for the isolating moving contact from the first motion range to the second motion range;

[0109] Based on the phase transition relationship, establish the motion connection relationship between the first motion interval and the second motion interval. Based on the motion connection relationship, form the break exposure stroke extending from the phase transition position to the complete opening position of the isolating moving contact. According to the actual position formed by the isolating moving contact along the break exposure stroke, form the break exposure completion state of the isolating moving contact entering the complete opening target area.

[0110] The complete exposure state of the break refers to the state in which the actual outer contour of the isolating moving contact and the internal space enclosed by the actual outer contour enter the target area of ​​the complete opening of the isolating moving contact after the isolating moving contact has moved along the exposure stroke of the break.

[0111] The formation process of the stage transition relationship is as follows:

[0112] During the movement of the isolating moving contact along the first movement interval, the actual position of the isolating moving contact is continuously compared with the stage transition position. When the isolating moving contact has not yet reached the stage transition position, the isolating moving contact continues to move along the first movement interval. When the isolating moving contact reaches the stage transition position and the actual spatial state between the isolating stationary contact and the isolating moving contact satisfies the fracture forming criterion, the subsequent movement of the isolating moving contact switches from the first movement interval to the second movement interval. The stage transition relationship is formed by the aforementioned movement interval switching that occurs at the stage transition position.

[0113] The formation process of motion connection, fracture surface exposure stroke, and fracture surface exposure completion state is as follows:

[0114] After the isolating moving contact completes the transition from the first motion interval to the second motion interval, the transition position is taken as the starting point of the second motion interval, so that the isolating moving contact continues to move from the transition position to the complete opening position along the original separation direction. The end position of the first motion interval and the starting position of the second motion interval are both located at the transition position. The continuous connection of the two motion intervals at the transition position forms a motion connection relationship.

[0115] Starting from the stage transition position, the stroke formed by the continuous movement of the isolating moving contact from the stage transition position along the second motion interval to the complete opening position constitutes the break exposure stroke;

[0116] During the movement of the isolating moving contact along the exposed stroke of the break, the current actual position and orientation of the isolating moving contact are obtained based on the angle value output by the absolute rotary encoder, the position of the shaft center in the spatial coordinate system, and the geometric dimensions of the isolating moving contact relative to the shaft center. Based on this, the spatial range occupied by the current actual outer contour of the isolating moving contact is obtained. When the current actual outer contour of the isolating moving contact and the internal space enclosed by the actual outer contour enter the target area of ​​the complete opening of the isolating moving contact, the broken exposure is completed.

[0117] The dual-reference fracture forming module aims to reduce the influence of the theoretical position or transmission deviation of the mechanism on the judgment of the actual fracture formation. It establishes a relative spatial relationship by using the actual positions of the isolating stationary contact and the isolating moving contact, and forms a fracture spatial relationship by combining the separation direction of the isolating moving contact. This spatial relationship serves as the constraint basis for the separation process to establish the fracture forming reference. After the isolating action is released, the continuous separation stroke of the isolating moving contact is divided into a first motion interval and a second motion interval according to the stage transition position, corresponding to the fracture formation stage and the fracture exposure stage, respectively. Then, the stage transition is limited according to the fracture forming reference, and the motion connection between the two motion intervals is established to form the fracture exposure stroke and the fracture exposure completion state. This makes the fracture forming process more dependent on the actual spatial relationship between the two contacts, rather than simply relying on the theoretical opening position of the mechanism.

[0118] The fracture space verification interlocking module, based on the fracture exposure completion state, forms a temporary verification channel jointly defined by the isolation stationary contact and the isolation moving contact according to their actual positions. The solid fracture space between the isolation stationary contact and the isolation moving contact is verified by the state of the insulation verification component passing through the temporary verification channel. Based on the verification results, a safe isolation interlocking allowable state and a complete fracture observation state based on the fracture observation benchmark are formed.

[0119] Based on the completed fracture exposure state, the process of forming a temporary verification channel jointly defined by the stationary and moving isolation contacts includes:

[0120] Based on the completed state of the fracture exposure, and according to the actual positions of the isolating stationary contact and the isolating moving contact, a first verification boundary corresponding to the isolating stationary contact and a second verification boundary corresponding to the isolating moving contact are formed respectively. Based on the relative positions between the first verification boundary and the second verification boundary, the spatial range between the two verification boundaries is defined, forming a verification space jointly defined by the first verification boundary and the second verification boundary.

[0121] Using the direction of travel of the insulation verification component as the direction of channel extension, a continuous temporary verification channel is formed in the verification space along the direction of channel extension.

[0122] The first verification boundary refers to the actual outer contour of the isolating stationary contact facing the solid fracture space; the second verification boundary refers to the actual outer contour of the isolating moving contact facing the solid fracture space; the verification space refers to the spatial range jointly defined by the first verification boundary, the second verification boundary, and the cross-sectional dimensions of the insulating verification component; the temporary verification channel refers to the spatial range within the verification space that extends continuously from one side of the verification space to the other side along the direction of travel of the insulating verification component.

[0123] The formation process of the first verification boundary, the second verification boundary, and the verification space is as follows:

[0124] After the fracture exposure is completed, the positions of the isolation stationary contact and the isolation moving contact are represented using the aforementioned spatial coordinate system. The actual installation position obtained from three measurement points on the outer surface of the isolation stationary contact is taken as the actual position of the isolation stationary contact at this time. Based on the angle value output by the absolute rotary encoder in the fracture exposure completed state, the position of the shaft center in the spatial coordinate system, and the geometric dimensions of the isolation moving contact relative to the shaft center, the actual position and actual orientation of the isolation moving contact are obtained. Based on the actual positions and actual orientations of the two contacts, the actual outer contours of the two contacts facing the solid fracture space are obtained respectively. The outer contour of the isolation stationary contact facing the solid fracture space is taken as the first verification boundary, and the outer contour of the isolation moving contact facing the solid fracture space is taken as the second verification boundary.

[0125] Along the direction in which the first verification boundary and the second verification boundary are opposite to each other, the space between the first verification boundary and the second verification boundary is taken as the extension range of the verification space along this direction. The lateral range of the verification space in the direction perpendicular to the passage is defined according to the actual cross-sectional size of the insulating verification component perpendicular to the passage direction. The verification space is formed by the extension range and the lateral range together.

[0126] The process of creating a temporary verification channel is as follows:

[0127] The direction of travel is formed by the movement of the insulation verification component from one side of the verification space to the other, and this direction of travel is used as the extension direction of the channel. According to the cross-sectional dimensions of the insulation verification component perpendicular to the direction of travel, a corresponding spatial range is continuously drawn from one side of the verification space to the other side along the extension direction of the channel, so that the spatial range is located between the first verification boundary and the second verification boundary, and extends continuously from one side of the verification space to the other side. This continuously extended spatial range is used as a temporary verification channel.

[0128] The process of verifying the physical break space between the isolating stationary contact and the isolating moving contact using the insulation verification component to check the passage state of the temporary verification channel includes:

[0129] Based on the temporary verification channel, the insulation verification component is driven to travel along the extension direction of the channel in the verification space. According to the actual passage result of the insulation verification component between the first verification boundary and the second verification boundary, a passage passing state or a passage blocked state is formed. Based on the passage passing state, a verification passing result of the actual break space is formed. Based on the passage blocked state, a verification failing result of the actual break space is formed.

[0130] The "passing through state" refers to the state in which the insulation verification component can pass continuously from one end to the other along the temporary verification channel without being blocked by the actual outer contour of the two contacts; the "passing through obstructed state" refers to the state in which the insulation verification component is blocked by the actual outer contour of the isolating stationary contact or isolating moving contact while passing through the temporary verification channel and cannot continue to the other end.

[0131] The process of forming the passage through state, the passage obstruction state, and the verification results is as follows:

[0132] One end of the insulation verification component is placed in one side opening of the temporary verification channel, and the insulation verification component is pushed through along the extension direction of the channel; when the insulation verification component continuously passes through from one side opening to the other side opening, a passing state is formed; when the insulation verification component is blocked by the actual outer contour of the isolating stationary contact or isolating moving contact and stops between the two openings, a passing obstruction state is formed; the passing state and the passing obstruction state respectively form the verification pass result and the verification fail result.

[0133] The process of establishing a safety isolation interlocking permissible state and a complete fracture observation state based on the fracture observation benchmark, according to the verification results, includes:

[0134] Based on the verification results of the physical break space and the isolation interlock release status, establish the interlock correspondence between the verification results and the isolation interlock release status, and form a safety isolation interlock permission status according to the interlock correspondence.

[0135] Based on the completed state of fracture exposure and the fracture observation benchmark, establish the observation correspondence between the physical fracture space and the external observation position along the observation path to form the fracture exposure observation state. Establish the fracture verification correspondence between the verification pass result and the fracture exposure observation state. Based on the fracture verification correspondence, form the complete fracture observation state.

[0136] The safety isolation interlock permission state refers to the state where the physical break space formation verification result is passed and the isolation interlock release state exists simultaneously; the break exposure observation state refers to the state where the physical break space is continuously observed from the external observation position along the observation path corresponding to the break observation reference, and the areas where the isolation stationary contacts are located and the complete opening target area of ​​the isolation moving contacts on both sides of the physical break space are observed simultaneously; the complete break observation state refers to the state where the break exposure observation state has been formed and the corresponding physical break space has simultaneously obtained the verification result passed.

[0137] The process of forming the interlocking correspondence and the permissible state of the safety isolation interlock is as follows:

[0138] After the verification result of the solid fracture space is formed, the output signal of the release position limit switch set at the release position of the isolation interlock mechanism is read. When the solid fracture space forms a verification result and the release position limit switch maintains the output release position signal, the verification result of the solid fracture space is established with the isolation interlock release state. When the solid fracture space forms a verification result and the isolation interlock release state exists at the same time, a safety isolation interlock permission state is formed.

[0139] The process of observing the correspondence, verifying the correspondence of the fracture surface, and forming the complete fracture surface observation state is as follows:

[0140] After the fracture surface is exposed, observation is carried out from the external observation position along the observation path toward the inside of the enclosed shell according to the established fracture observation benchmark. When the solid fracture space can be continuously observed from the external observation position along the observation path, and the areas where the isolation stationary contacts are located and the complete opening target area of ​​the isolation moving contacts on both sides of the solid fracture space are observed at the same time, the observation correspondence between the external observation position, the observation path and the solid fracture space is established, and the fracture exposure observation state is formed by the observation correspondence.

[0141] After the fracture surface is exposed and observed, a fracture surface verification correspondence is established between the fracture surface exposed and observed state and the verification results of the solid fracture surface space. When the fracture surface exposed and observed state and the verification results of the solid fracture surface space exist simultaneously, a complete fracture surface observation state is formed.

[0142] The fracture space verification interlocking module aims to further confirm the actual physical fracture space formed between the isolating stationary contact and the isolating moving contact, and use the verification results to establish the interlocking and observation states. After the fracture is exposed, a first verification boundary and a second verification boundary are formed according to the actual positions of the two contacts. The verification space is defined according to the relative positions of the two boundaries, and a continuous temporary verification channel is formed along the direction of the insulation verification component. The insulation verification component is driven to travel along the temporary verification channel, and a verification pass result or a verification fail result is formed according to the physical passage result. The verification pass result is then correlated with the isolation interlock release state and the fracture exposure observation state, respectively, to form the safe isolation interlock allowable state and the complete fracture observation state, so that the interlock allowable state and the fracture observation state are established on the basis of the actual physical fracture space verification.

[0143] Example 2: The technical solution of this embodiment of the invention differs from that of Example 1 in that:

[0144] like Figure 2 As shown, the collaborative control method for an integrated pole-mounted switch system with visible break points includes the following steps:

[0145] S1: Within the enclosed housing of the pole-mounted switch, a break observation reference corresponding to the external observation position is formed based on the area where the stationary isolating contact is located, the complete opening target area of ​​the moving isolating contact, and the physical break space between the two.

[0146] S2: Based on the main circuit interruption request, execute the main circuit interruption and arc extinguishing, and generate isolation action release conditions according to the completion status of the main circuit interruption and arc extinguishing;

[0147] S3: Establish the fracture forming reference based on the actual positions of the isolating stationary contact and the isolating moving contact. Based on the isolating action release condition, separate the isolating moving contact from the isolating stationary contact. Divide the separation process into the fracture forming stage and the fracture exposure stage. According to the fracture forming reference, control the isolating moving contact to enter the fracture exposure stage after the fracture forming stage is completed, and form the fracture exposure completed state.

[0148] S4: Based on the completed state of the fracture exposure, a temporary verification channel is formed by the actual positions of the isolating stationary contact and the isolating moving contact. The physical fracture space between the isolating stationary contact and the isolating moving contact is verified by the state of the insulation verification component passing through the temporary verification channel. Based on the verification results, a safety isolation interlocking allowable state and a complete fracture observation state based on the fracture observation benchmark are formed.

[0149] This collaborative control method aims to reduce the impact of mechanism position deviation on the judgment of actual fracture formation and to form a continuous control chain between external observation, fracture formation and physical space verification.

[0150] First, a fracture observation benchmark is established based on the area where the isolation stationary contact is located, the complete opening target area of ​​the isolation moving contact, and the physical fracture space, providing a spatial basis for external observation.

[0151] Subsequently, after the main circuit is interrupted and the arc is extinguished, the isolation action release condition is generated to avoid the disorderly connection between the main circuit interruption and the isolation action.

[0152] Then, based on the actual positions of the isolating stationary contact and the isolating moving contact, a fracture forming reference is established. The separation process of the isolating moving contact is divided into a fracture forming stage and a fracture exposure stage. The stage connection is controlled according to the reference to form a fracture exposure completed state.

[0153] Finally, a temporary verification channel is formed based on the actual positions of the two contacts. The physical break space is verified by the through-state of the insulation verification component. Based on the verification results, a safety isolation interlock permission state and a complete break observation state are formed. This allows the isolation state judgment to be based more on the actual contact position and physical break space, rather than simply relying on the mechanism's tripping state.
