Description

Technical Field

[0001] The present application relates to the field of low-voltage electrical appliances, and in particular to an energy storage operating mechanism for an isolating switch. Background Art

[0002] In the field of rotary switches or disconnectors, the fast action of the quick-closing unit layer is often achieved by relying on the energy storage operating mechanism.

[0003] The energy storage operating mechanism of a traditional rotary switch or disconnector often only supports manual closing and opening, as shown in CN205376364U, and does not have a shunt function (also called a remote tripping function), such as the structure shown in the rotary switch or disconnector.

[0004] With the continuous development of society, in some sub-sectors, it is necessary to realize remote opening of such rotary switches or disconnectors, that is, the excitation function. Obviously, it is not feasible to rely on the traditional energy storage operating mechanism.

[0005] At this time, a new energy storage operating mechanism (such as CN215578335U) has emerged in this field. It adds a shunt release (that is, the electromagnet in the patent) and a separation energy storage mechanism related to the shunt release (that is, the energy storage lock hook, trigger buckle, trigger shaft, and automatic release energy storage buckle in the patent) on the basis of the original mechanism that can only perform manual opening and closing. It uses the unlocking of the energy storage mechanism of the shunt release to achieve rapid opening, thereby realizing the remote shunt function.

[0006] However, the existing energy storage mechanism related to the shunt release adopts a rotating method for the internal energy storage lock hook, trigger buckle, trigger shaft and other components. Since the energy storage lock hook, trigger buckle, trigger shaft and the like of this rotating method need to perform rotational motion, some shaft designs are required, which invisibly increases the difficulty of molding many parts or components.

[0007] Therefore, how to design a more streamlined energy storage operating mechanism that can realize remote shunt function is a question worth considering. Summary of the Invention

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0027] In this application, unless otherwise specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly.

Example

[0029] like Figure 1-Figure 30 As shown, the embodiment of the present application is a disconnector having an energy storage operating mechanism 100 , which can realize manual opening, closing, and remote tripping (also called shunt tripping) of the disconnector, and is particularly applicable to stacked disconnectors.

[0030] The energy storage operating mechanism includes a housing, a main shaft 130 , a tripping mechanism 20 and an opening and closing mechanism 10 .

[0031] Here, the main shaft 130 is rotatably arranged relative to the housing, specifically rotatably arranged around an axis O. One end of the main shaft 130 here passes through the outside of the housing and is used to be connected to an operating handle for user operation.

[0032] The portion of the main shaft 130 located inside the housing cooperates with the tripping mechanism 20 and the opening and closing mechanism 10 respectively.

[0033] Here, the opening / closing mechanism 10 is used to directly form a transmission connection with the movable contact discs of the switch layer 200 (each switch layer 200 below the operating mechanism). In other words, the operation of the opening / closing mechanism 10 can directly drive the movable contact discs of the switch layer 200 to rotate. This transmission connection (formed through plugging, with the first layer of movable contact discs plugged into the output portion of the opening / closing mechanism 10, and adjacent movable contact discs plugged into each other) is conventional technology and will not be further described here.

[0034] The opening and closing mechanism 10 also features a device with an energy storage spring, enabling it to open and close in response to the rotation of the main shaft 130. Clearly, this mechanism 10 must have both an opening and a closing position. The transition from the opening position to the closing position is called a closing operation, while the transition from the opening position to the closing position is called an opening operation. Whether operating in an opening or closing operation, the opening and closing mechanism 10 first stores energy and then releases it, enabling the dynamic contact disc to rotate rapidly.

[0035] Here, there are two specific forms of the opening and closing mechanism 10 , one is a double locking assembly 170 form, and the other is a single locking assembly 170 form.

[0036] As a double locking assembly 170 mode, the opening and closing mechanism 10 includes a driving disk 140 , an opening and closing seat 150 , a second energy storage spring 160 , and two locking assemblies 170 .

[0037] The drive disc 140 is connected to the main shaft 130 and rotates synchronously with the main shaft 130. Here, the synchronous rotation arrangement of the drive disc 140 and the main shaft 130 actually involves a radial engagement between the two (which can be understood as a rotational engagement). There are many ways to achieve this radial engagement. As a preferred approach, the drive disc 140 is provided with a mating hole 141, into which the main shaft 130 is at least partially inserted, forming a radial engagement (which can be understood as a rotational engagement). This structure is relatively simple. Of course, other approaches can also be used, such as providing a pin extending radially through the main shaft 130, providing a drive seat on the drive disc 140, and providing a slot 111 on the drive seat that mates with the pin. This approach can also achieve a radial engagement and achieve synchronous motion.

[0038] The drive disc 140 comprises a main body 140a, two unlocking portions 140b, and a first abutting portion 140c. While there are many material options for the drive disc 140, a preferred option is to use a metal component (e.g., stainless steel). The unlocking portions 140b are formed as two lugs on the main body 140a, and the unlocking portions 140b and the main body 140a are flat. This structure ensures that the unlocking portions 140b and the main body 140a have good strength and are very simple to manufacture (requiring only cutting, eliminating some bending steps). The first abutting portion 140c is formed by bending a portion of the drive disc 140 toward the direction of the splitter / combiner seat 150 (specifically, toward the interior of the first mounting slot 151). This makes the first abutting portion 140c very simple to form, requiring only cutting and a single bending step.

[0039] The splitter / combiner seat 150 is rotatably mounted with the base 110. The splitter / combiner seat 150 is made of engineering plastic and is provided with a first mounting groove 151 and two locking grooves 152. The first mounting groove 151 has a second abutment portion 153 on its wall. The first abutment portion 140c is also located within the first mounting groove 151. The two abutment portions are designed to engage with the second energy storage spring 160. Both locking grooves 152 are formed on the circumferential sidewall 154 of the splitter / combiner seat 150. The circumferential sidewall 154 refers to the radial sidewall of the splitter / combiner seat 150.

[0040] A second energy storage spring 160 is disposed in the first mounting slot 151. Here, the second energy storage spring 160 is a torsion spring, with its two end legs (also known as ends) respectively contacting the first abutting portion 140c and the second abutting portion 153. When the first abutting portion 140c rotates with the drive disk 140, if the splitter / combiner seat 150 is locked by the locking assembly 170, the second abutting portion 153 is essentially stationary, causing the second energy storage spring 160 to deform and generate energy. When the locking assembly 170 is unlocked, the second energy storage spring 160 can quickly drive the splitter / combiner seat 150 to the next position. Of course, the second energy storage spring 160 is not limited to a torsion spring; it can also be a compression spring similar to an annular (not a closed annular) shape.

[0041] Two locking assemblies 170 are slidably mounted on the base 110 of the housing and are located adjacent to the opening / closing seat 150. Each locking assembly 170 corresponds to a locking slot 152 and an unlocking portion 140b. The locking assembly 170 and the corresponding locking slot 152 can be in either an unlocked or locked state. Each locking assembly 170 is resilient, and the rotation center of the opening / closing seat 150 is a first imaginary center P. The angle between a first imaginary line connecting the two locking slots 152 and the first imaginary center P is a first angle A (e.g., 90°, though this is not a specific requirement; any angle that ensures sufficient separation between the moving and stationary contacts of the switch layer 200 is acceptable, as the first angle A determines the rotation angle of the underlying movable contact disc). The angle between a second imaginary line connecting the two locking assemblies 170 and the first imaginary center P is a second angle B (e.g., 180°, though this is not a specific requirement; any angle greater than the first angle A is acceptable). Of course, here, the angle between the third imaginary lines connecting the two unlocking parts 140b to the first imaginary center P is the third angle C, and the second angle B is also greater than the third angle C. The specific setting of the third angle C here can be set according to the position of the unlocking part 140b, as long as it can ensure that the unlocking part 140b unlocks the locking assembly 170.

[0042] Therefore, when one locking assembly 170 is in the locked state, the other locking assembly 170 is in the unlocked state. As the main shaft 130 rotates, the second energy storage spring 160 deforms under the action of the first abutment portion 140c. After the unlocking portion 140b triggers the locking assembly 170 that was originally in the locked state to change to the unlocked state, the separation and combination seat 150 quickly rotates to the next position under the action of the second energy storage spring 160, and the locking assembly 170 that was originally in the unlocked state is changed to the locked state. As long as any one locking assembly 170 is in the locked state, the separation and combination seat 150 is actually locked to the housing, that is, the separation and combination seat 150 is stationary relative to the housing. Only when the locking assembly 170 is unlocked can the separation and combination seat 150 rotate relative to the housing.

[0043] Here, as Figures 28-30 As shown, when the lower switch layer 200 is in the open state (when closing is desired), the locking assembly 170 on the left side of the figure is locked, while the locking assembly 170 on the right side is unlocked. When the main shaft 130 rotates clockwise, the rotation of the first abutting portion 140c causes the second energy storage spring 160 to deform. As the unlocking portion 140b on the left side triggers the locking assembly 170 on the left side to unlock (i.e., the distance from the start of rotation to the unlocking portion 140b contacting the locking assembly 170 is called the predetermined distance), the opening and closing seat 150, under the action of the second energy storage spring 160, rapidly rotates to the closed position. At this point, the locking assembly 170 on the right side aligns with the locking groove 152. Under the action of its own elastic force, the locking assembly 170 partially enters the locking groove 152, locking the locking assembly 170. Of course, to open the switch layer 200, a similar operation is performed by rotating the main shaft 130 in the opposite direction. The process is exactly the opposite of the closing process described above and will not be further described here.

[0044] By adopting two sets of locking structures, only one set of locking components 170 will be driven by the unlocking portion 140b, whether in closing operation or opening operation, so the wear on the locking components 170 will be relatively small, so the reliability of the mechanism is better under this method.

[0045] Here, since the two sets of locking assemblies 170 are essentially identical in structure, taking one set of locking assemblies 170 as an example, it includes a locking member 171 and an elastic member 172. The locked state means that the locking member 171 is at least partially within the locking groove 152 to restrict the rotation of the separation seat 150, while the unlocked state means that the locking member 171 is completely out of the locking groove 152. In the unlocked state, the elastic member 172 is deformed and applies a biasing force to the locking member 171 toward the separation seat 150. Only when the locking groove 152 rotates with the separation seat 150 to align with the corresponding locking member 171, the biasing force causes the locking member 171 to return to the locked state.

[0046] Here, there are many options for the elastic member 172, such as a compression spring, a tension spring, a leaf spring, a disc spring, or even a plastic elastic foot integrally formed on the locking member 171. As a preferred embodiment, the elastic member 172 is a spring leaf, which is relatively simple to form and relatively easy to set up.

[0047] Here, the spring sheet includes a first plate portion 172a, a bent portion 172b, and a second plate portion 172c. The first plate portion 172a and the second plate portion 172c are connected by the bent portion 172b. The first plate portion 172a is fixed to the housing, and the second plate portion 172c penetrates the locking member 171 to form a mating engagement with the locking member 171. This three-part arrangement allows the first plate portion 172a to secure the housing, while the second plate portion 172c and the bent portion 172b interact with the locking member 171 to provide a biasing force for the locking member 171.

[0048] Here, the first plate portion 172a can be fastened to the base 110 in a variety of ways, such as by fasteners (screws, etc.) or by an interference fit with the base 110. As a preferred embodiment, the base 110 has a slot 111, and the first plate portion 172a forms an interference fit with the slot 111. This fit makes both the base 110 and the first plate portion 172a easier to manufacture and conveniently assemble.

[0049] The spring piece can be designed in a variety of shapes, ranging from an S-shape to a U-shape. For example, the second plate portion 172c is longer than the first plate portion 172a. The first and second plate portions 172a and 172c are connected on the same side of the bent portion 172b, forming a semi-enclosed first space F. In this arrangement, the portion of the rib 112 that forms part of the retaining groove 111 is located within the first space F. This arrangement ensures a tight fit between the spring piece and the base 110, ensuring stable installation of the spring piece.

[0050] Regarding the second plate portion 172c, the locking member 171 has a through hole 171a. The second plate portion 172c passes through one end of the through hole 171a and exits at the other end. The through hole 171a, where the second plate portion 172c passes, has a guide section with gradually decreasing dimensions, making it very easy to insert the second plate portion 172c.

[0051] In addition to the through-hole 171a, the locking member 171 also has a locking protrusion 171b and an unlocking protrusion 171c. The locking protrusion 171b is configured to engage with the locking groove 152, while the unlocking protrusion 171c is configured to engage with the unlocking portion 140b. The unlocking protrusion 171c has a vertex S and slopes M on either side of the vertex S. During unlocking, the unlocking portion 140b gradually moves along the slopes M on one side of the vertex S to the vertex S (causing the locking member 171 to slide) and then moves out from the other side of the vertex S.

[0052] Here, the sliding of the locking member 171 refers to sliding relative to the base 110. This sliding can take many forms. It can be rotational, for example, with a positioning axis provided on the base 110, and the locking member 171 rotating about the positioning axis. Another example is linear sliding (movement along a straight line), where the base 110 is provided with a guide rib 113, and the locking member 171 is arranged to slide linearly along the guide rib 113.

[0053] As a single locking assembly 170, most of the structures of the separation and combination mechanism 10 in this mode are similar to those of the double locking assembly 170 scheme, which includes a drive disk 140, a separation and combination seat 150, a second energy storage spring 160, and a locking assembly 170.

[0054] The transmission method of the driving plate 140 and the main shaft 130 is the same as that of the double locking assembly 170, and will not be repeated here.

[0055] The drive disk 140 is similarly provided with a main body 140a, an unlocking portion 140b, and a first abutting portion 140c. Here, there are also two unlocking portions 140b (acting on the same locking assembly 170, but in different directions). The remaining structure is the same as that of the dual locking assembly 170 and will not be further described here.

[0056] The opening and closing seat 150, the rotation method and the connection method of the second energy storage spring 160 are the same as those of the double locking assembly 170, and will not be repeated here. The main difference is that the opening and closing seat 150 has a placement groove 155, which is used to accommodate the locking assembly 170.

[0057] The side wall 154 of the opening and closing seat 150 will no longer be provided with two locking grooves 152. The two locking grooves 152 are opened on the middle seat 115 of the shell. One locking groove 152 corresponds to the switch layer 200 being in the open state, and the other locking groove 152 corresponds to the switch layer 200 being in the open and closed state.

[0058] The locking assembly 170 includes a locking member 171 and an elastic member 172 , and is configured to slide vertically. It can be said that the sliding direction is parallel to the length direction of the axis O.

[0059] The elastic member 172 is positioned between the bottom of the placement slot 155 and the locking member 171. There are many options for the elastic member 172, including a compression spring, a tension spring, a leaf spring, a disc spring, or even a plastic elastic foot integrally formed on the locking member 171. Preferably, the elastic member 172 is a compression spring, which is easier to install.

[0060] Locking member 171 also has a locking protrusion 171b and an unlocking protrusion 171c. Locking protrusion 171b is configured to engage with locking groove 152, while unlocking protrusion 171c is configured to engage with unlocking portion 140b. Unlocking protrusion 171c has a vertex S and slopes M on either side of vertex S. During unlocking, unlocking portion 140b gradually moves along slope M on one side of vertex S to vertex S (causing locking member 171 to slide) and then moves out from the other side of vertex S.

[0061] The locked state means that the locking protrusion 171b is in the locking groove 152 to restrict the rotation of the splitter 150, and the unlocked state means that the locking protrusion 171b is completely out of the locking groove 152. In the unlocked state, the elastic component 172 is in a deformed state and applies a biasing force to the locking member 171 to move in the direction of the middle seat 115. Only when the next locking groove 152 rotates with the splitter 150 to align with the locking member 171, the biasing force causes the locking member 171 to return to the locked state. As long as the locking assembly 170 is in the locked state, the splitter 150 is actually locked to the housing, that is, the splitter 150 is stationary relative to the housing. Only when the locking assembly 170 is unlocked can the splitter 150 rotate relative to the housing.

[0062] Here, as Figure 14-16 As shown, when the lower switch layer 200 is in the open state (when closing is desired), the locking assembly 170 is locked in the right locking groove 152. When the main shaft 130 rotates clockwise, the rotation of the first abutting portion 140c causes the second energy storage spring 160 to deform. As the right unlocking portion 140b triggers the right side of the locking assembly 170 to contract, unlocking it (the distance from the start of rotation to the unlocking portion 140b contacting the locking assembly 170 is called the predetermined distance). Under the action of the second energy storage spring 160, the opening and closing seat 150 rapidly rotates to the closed position. At this point, the locking assembly 170 aligns with the left locking groove 152. Under the action of its own elastic force, the locking assembly 170 partially enters the locking groove 152, locking it. Of course, if the switch layer 200 is to be opened, a similar operation is performed by rotating the main shaft 130 in the opposite direction. This process is exactly the opposite of the closing process described above and will not be further described here.

[0063] This single locking assembly 170 solution requires very few parts, so it has advantages in assembly compared to the double locking assembly 170 solution.

[0064] Regardless of the single locking assembly 170 solution or the double locking assembly 170 solution, these opening and closing mechanisms 10 have the function of energy storage operation.

[0065] For the tripping mechanism 20, it also has an energy storage effect, which is the key to realize shunt tripping (that is, remote operation). The tripping mechanism 20 includes a first energy storage spring 210 , an energy storage seat 220 , a locking member 230 , a first spring 240 , a retaining member 250 and a second spring 260 .

[0066] The energy storage seat 220 is sleeved on the main shaft 130 and is in transmission connection with the main shaft 130 , that is, the energy storage seat 220 can be driven to rotate by the rotation of the main shaft 130 .

[0067] The first energy storage spring 210 is connected between the energy storage base 220 and the housing. Specifically, the energy storage base 220 is provided with a second mounting groove 220a. The first energy storage spring 210 is positioned within the second mounting groove 220a, with one end abutting against the energy storage base 220 and the other end abutting against the upper cover 105 of the housing. This allows the first energy storage spring 210 to store energy while the main shaft 130 drives the opening and closing mechanism 10 to close the switch. While the first energy storage spring 210 is a torsion spring, an annular (non-enclosed annular) compression spring could also be used.

[0068] The locking member 230 slides with the housing, specifically along a first linear direction X1, and has a locked state and an unlocked state. In the locked state, the energy storage base 220 is restricted from rotating, thereby maintaining the first energy storage spring 210 charged. This locked state is achieved by providing a locking groove 220b on the circumferential sidewall of the energy storage base 220 and a locking protrusion 230a on the locking member 230. As the main shaft 130 drives the opening and closing mechanism 10 to close, the energy storage base 220 rotates with the main shaft 130 (accumulating energy in the first energy storage spring 210), and the locking groove 220b of the energy storage base 220 gradually moves into alignment with the locking protrusion 230a. Under the action of the first spring 240 (which provides a biasing force to restore the locking member 230 to the locked state), the locking protrusion 230a extends into the locking groove 220b, thereby achieving the locked state (of course, this locked state is maintained by the retaining member 250).

[0069] The retaining member 250 is slidably disposed with respect to the housing, specifically, along the second linear direction X2. The retaining member 250 has a first position Z1, which holds the latch 230 in the locked state, and a second position Z2, which releases the latch 230. In this embodiment, the latch 230 is provided with a first retaining wall 230b, and the retaining member 250 is provided with a second retaining wall 250a. When the retaining member 250 is in the first position Z1, the first retaining wall 230b abuts against the second retaining wall 250a, effectively blocking the latch 230's "escape path" (movement toward the unlocked state), thereby ensuring that the latch 230 remains stably locked. The second position Z2 means that the retaining member 250 will no longer block the movement of the locking member 230, so the locking member 230 can move to the unlocked state (the force pushing the locking member 230 to move is specifically: the first energy storage spring 210 promotes the reaction force on the rotation of the energy storage seat 220, the locking groove 220b of the energy storage seat 220 will disengage from the locking boss 230a, the locking boss 230a slides under the push of the circumferential side wall of the energy storage seat 220, and the first spring 240 will gradually compress). There are many specific ways to form the first resisting wall 230b and the second resisting wall 250a. The first resisting wall 230b and the second resisting wall 250a can be part of two protruding structures; or, as in the present embodiment, the first resisting wall 230b can be part of the protruding structure and the second resisting wall 250a can be part of the groove structure; or the first resisting wall 230b can be part of the groove structure and the second resisting wall 250a can be part of the protruding structure. The first retaining wall 230 b and the locking protrusion 230 a are disposed on different surfaces of the locking member 230 .

[0070] One end of the second spring 260 abuts against the retaining member 250, and the other end abuts against the housing. Here, the second spring 260 provides a biasing force on the retaining member 250 toward the first position Z1. This biasing force toward the first position Z1 can be manifested in two ways: first, when the release 300 is reset, this biasing force causes the retaining member 250 to slide to the first position Z1. Second, when the release 300 is not actuated, the retaining member 250 remains stable in the first position Z1 (preventing it from moving out of the first position Z1 due to the reaction force of the locking member 230).

[0071] No matter first spring 240 or second spring 260, what adopts here is compression spring. Of course, in addition, also can adopt torsion spring, shrapnel, or the elastic plastic foot on one body of locking member 230 and retaining member 250.

[0072] The first linear direction X1 and the second linear direction X2 are arranged at an angle. In this embodiment, the two are arranged perpendicularly. This perpendicular arrangement is relatively easy to use in terms of space utilization and assembly. Of course, other than this, an acute angle or an obtuse angle can also be selected.

[0073] The release 300, in this embodiment, employs a magnetic flux release. Essentially, it utilizes the principle of an electromagnet, actuating when a coil receives a trip signal. The actuating portion 300a of the release 300 serves as its push rod. Because the retaining member 250 is positioned on one side of the actuating portion 300a of the release 300, actuation of the release 300 drives the retaining member 250 to the second position Z2. This frees the retaining member 250 from securing the latch 230, releasing the latch 230 from the energy storage base 220. The energy storage base 220 rotates due to the first energy storage spring 210, causing the main shaft 130 to drive the tripping mechanism 10 to perform an opening operation.

[0074] There are many ways to achieve the coordination between the retaining member 250 and the actuating portion 300a of the trip unit 300. As one approach, the retaining member 250 includes a driving portion 250b that extends onto the motion trajectory of the actuating portion 300a of the trip unit 300. Here, the driving portion 250b is a boss. When the trip unit 300 is actuated, the retaining member 250 is moved by pushing the driving portion 250b. In this approach, the driving portion 250b and the second retaining wall 250a are located on different surfaces of the retaining member 250. This design of the driving portion 250b eliminates the need for the entire retaining member 250 structure to be located on one side of the actuating portion 300a of the trip unit 300. Instead, only one driving portion 250b needs to extend to one side. This facilitates the overall installation design of the retaining member 250 and fully utilizes the space within the housing.

[0075] Here, there are many ways to give the trip signal, for example, it can be given by the host computer through the communication interface, or it can be given by the control circuit board of the isolation switch itself, either way is acceptable.

[0076] With such a structure, both the locking member 230 and the retaining member 250 are arranged to slide along a straight line. Compared with the rotation setting method used in the prior art, such a structure does not require the additional setting of a rotating shaft related to the rotation and simplifies the specific shape of the components. It is only necessary to meet the requirements of locking and unlocking the energy storage seat 220 by the locking member 230 and retaining and releasing the locking member 230 by the retaining member 250.

[0077] After actuation, the trip unit 300 is reset via a reset mechanism. This reset mechanism can be designed in a variety of ways. It can be a structure within the trip unit 300 itself, such as a reset spring (when actuated, the magnetic field's force is greater than the spring's force; after the magnetic field disappears, the spring drives the actuator 300a to reset), or a bidirectional magnetic latching relay (one coil is energized for actuation, the other for reset). Alternatively, it can be implemented as an additional mechanical structure.

[0078] As an additional mechanical reset mechanism, a reset rod 270 and a third spring 280 are employed. These two components also form part of the trip mechanism 20. In this configuration, the reset rod 270 slides linearly, its direction parallel to the actuation direction of the electromagnetic release 300. In this configuration, the reset rod 270, driven by the energy storage base 220, slides to the third position Z3 and resets the actuated release 300. This means that while the tripping base 150 is opening, the reset rod 270 resets the release 300.

[0079] Here, the third spring 280 abuts between the reset rod 270 and the housing, storing energy when the reset rod 270 slides to the third position Z3. The reset rod 270 and the energy storage base 220 are not always in transmission connection. Instead, they only form a transmission connection when the energy storage base 220 is rotated by the first energy storage spring 210 (also known as the opening operation). During the closing operation (when the energy storage base 220 rotates due to the rotation of the main shaft 130), the two can be disengaged, at which point the reset rod 270, under the action of the third spring 280, returns to the fourth position Z4.

[0080] The main way to achieve this non-continuous engagement is to provide the reset rod 270 with an engaging portion I 271 and the energy storage seat 220 with an engaging portion II 221. The engaging portion II 221 here is a sector-shaped tooth, and the engaging portion II 221 is a bar-shaped tooth. The number of teeth of both is relatively small, for example, two. Of course, in addition to two, three, four, or more can be used. As long as the reset rod 270 and the energy storage seat 220 can disengage after moving a certain distance, the actual setting can be based on the rotation angle of the energy storage seat 220, as long as the distance of the meshing transmission between the two does not exceed 3 / 4 of the total stroke of the energy storage seat 220.

[0081] The reset lever 270 includes a reset portion 270 a , a transmission portion 270 b , and an assembly portion 270 c .

[0082] The reset portion 270a is used to cooperate with the trip, that is, the reset portion 270a is located on one side of the actuating portion 300a of the trip unit 300. The third position Z3 mentioned above is the direction in which the reset portion 270a is toward the actuating portion 300a, and the fourth position Z4 is the direction in which the reset portion 270a is away from the actuating portion 300a.

[0083] The engaging portion I 271 is provided on the transmission portion 270b.

[0084] The assembly portion 270 c is used to be assembled with the housing and is also the portion that the third spring 280 is used to abut.

[0085] Through such a structure, each part of the reset rod 270 has its own function, which can simplify the complexity of the reset rod 270 and is conducive to the design of the reset rod 270 in the sliding setting form.

[0086] For the above components, they can be arranged in a scattered manner in the housing, or can be designed in a modular manner.

[0087] As a more preferred approach, modular assembly is adopted.

[0088] In this manner, the housing includes an upper cover 105 , a middle seat 115 and a base 110 .

[0089] A first installation space 110 a having an opening is provided on the base 110 , and the opening / closing mechanism 10 and the tripper 300 are disposed in the first installation space 110 a .

[0090] The center base 115 and the upper cover 105 form a single module. They are fastened together using screws, though snap-fit fastening or ultrasonic welding are also possible. Together, the center base 115 and the upper cover 105 form a second mounting space, within which the trip mechanism 20 is located. The reset portion 270a of the reset lever 270 is exposed outside the center base 115 and the actuator portion 300a of the trip unit 300.

[0091] That is, the tripping mechanism 20 is installed in the second installation space, the opening and closing mechanism 10 and the magnetic flux release 300 are installed in the first installation space 110a, and then the module formed by the middle seat 115 and the upper cover 105 is fixed to the base 110 to complete the assembly.

[0092] Such a modular assembly structure does not make the parts look messy as a whole. At the same time, the two mechanisms (tripping mechanism 20 and separation and combination mechanism 10) are assembled in different spaces, which is conducive to automated production and prevents workers from mixing up parts and materials.

[0093] The module formed by the middle base 115 and the upper cover 105 can be fixed to the base 110 in a variety of ways. The upper cover 105 and the base 110 can be fastened together with screws to close the opening of the first installation space 110a (equivalent to the middle base 115 also being located in the first installation space 110a). Alternatively, the middle base 115 and the base 110 can be fastened together with screws to close the opening of the first installation space 110a. Either method is preferred.

[0094] For the trip unit 300, it may not be installed in the first installation space 110a, but may be installed in the second installation space, which also has the effect of modular installation.

[0095] Here, for the installation of the energy storage seat 220, a first receiving slot 115a is provided in the middle seat 115, and a second receiving slot 105a is provided in the upper cover 105. These two receiving slots correspondingly and jointly accommodate the energy storage seat 220. This structural design is conducive to reducing the size of the upper cover 105 or the middle seat 115, ensuring the strength of the upper cover 105 or the middle seat 115. If the entire energy storage seat 220 is accommodated in the upper cover 105 or the middle seat 115, it will undoubtedly require a very large upper cover 105 or the middle seat 115, which is not conducive to the injection molding of the upper cover 105 or the middle seat 115, nor is it conducive to improving the strength of the upper cover 105 or the middle seat 115 (because the larger the slot, the lower the strength).

[0096] The upper cover 105 defines a third receiving slot 105b, into which the latch 230 slides. The center base 115 includes an abutment plate 115b. Once the center base 115 and the upper cover 105 are secured, the abutment plate 115b seals the opening of the third receiving slot 105b. Here, the first spring 240 effectively abuts against the center base 115 (a wall of the third receiving slot 105b). This structural design facilitates assembly due to the relatively small size of the latch 230, allowing it to be fully accommodated within the upper cover 105 (the third receiving slot 105b). (Having a slot for the latch 230 in both the center base 115 and the upper cover 105 would undoubtedly be difficult to assemble, as alignment would be necessary.) It also simplifies the molding of the center base 115 (requiring only a single abutment plate 115b to seal the opening of the third receiving slot 105b).

[0097] The upper cover 105 defines a fourth receiving slot 105c, into which the retaining member 250 slides. After the middle seat 115 is secured to the upper cover 105, the abutment plate 115b seals the opening of the fourth receiving slot 105c. This structural design facilitates installation due to the relatively small size of the retaining member 250, allowing it to be completely accommodated within the upper cover 105 (fourth receiving slot 105c). This also simplifies the molding of the middle seat 115. The reasons for this are similar to those for the installation of the locking member 230 and will not be further elaborated here.

[0098] In order to achieve that the disconnector can be manually opened and closed after the tripping mechanism 20 completes energy storage. Here, the transmission between the main shaft 130 and the energy storage seat 220 is not always in transmission connection, but in a one-way transmission connection. This one-way transmission connection means that the two will form a transmission connection only during the period when the main shaft 130 drives the opening and closing mechanism 10 to perform the closing operation and the energy storage seat 220 rotates due to the first energy storage spring 210. The one-way transmission connection structure here is realized by a first abutment structure provided on the main shaft 130 and a second abutment structure on the energy storage seat 220. There are many specific implementation methods. Taking the first abutment structure as an example, a transmission pin 135 is used, specifically, the transmission pin 135 passes through the main shaft 130 in the radial direction to form two protruding ends. The second abutment structure is the abutment surface 220c of the two bosses (or the two abutment surfaces 220c of the grooves) provided on the energy storage seat 220. When the transmission pin 135 abuts against the abutment surface 220c, transmission is formed (abutment occurs only during the period when the main shaft 130 drives the opening and closing mechanism 10 to perform the closing operation and the energy storage seat 220 rotates due to the first energy storage spring 210). The reverse rotation of the main shaft 130 can realize manual opening (also called manual opening operation when the trip mechanism 20 is in the energy storage state), and of course, closing can also be performed again (also called manual closing operation when the trip mechanism 20 is in the energy storage state).

[0099] In actual use, to ensure that the opening and closing mechanism 10 can effectively open, the tripping mechanism 20 can also directly trigger the locking assembly 170 to unlock it, prompting the opening and closing mechanism 10 to complete the opening operation. Of course, the direct triggering of the locking assembly 170 here can be delayed after the driving disk 140 triggers the unlocking of the locking assembly 170, or it can be simultaneous with the unlocking of the locking assembly 170 triggered by the driving disk 140, or it can be unlocked before the driving disk 140 triggers the unlocking of the locking assembly 170. Regardless of the order, as long as the locking assembly 170 is unlocked in two ways, allowing the opening operation of the opening and closing mechanism 10 to be completed, it is acceptable. With this structure, as long as either mechanical structure is still effective, the opening and closing mechanism 10 can be opened after the release 300 is actuated.

[0100] The specific structure includes a trigger block 400 and a fourth spring 410. The trigger block 400 has a fifth position Z5 and a sixth position Z6. The trigger block 400 is positioned on one side of the actuating portion 300a of the trip unit 300. Upon actuation of the trip unit 300, the trigger block 400 moves to the fifth position Z5 (where the fourth spring 410 stores energy). The fourth spring 410 abuts between the trigger block 400 and the base 110. After the trip unit 300 is reset, the fourth spring 410 drives the trigger block 400 back to the sixth position Z6.

[0101] Taking the single locking assembly 170 as an example, the trigger block 400 is slidably mounted on the base 110, specifically, slidably mounted in a direction parallel to the axis O. Since the locking member 171 is mounted in the opening / closing seat 150 via the placement slot 155, the locking member 171 has an actuated protrusion 171d extending from the peripheral sidewall 154 of the opening / closing seat 150. When the opening / closing seat 150 is in the closed position, the trigger block 400 is in the sixth position Z6, and the actuated protrusion 171d is located in the motion trajectory of the trigger block 400. After the release 300 is actuated, the trigger block 400 moves to the fifth position Z5, pressing down the actuated protrusion 171d to unlock the locking assembly 170, and the opening / closing seat 150 rotates to the open position under the second energy storage spring 160.

[0102] Of course, although the above example is a structure of a single locking assembly 170, it is also applicable to a structure of a double locking assembly 170 (for example, located next to the locking assembly for closing the switch).
