Description

Technical Field

[0001] This invention relates to an electrical product, specifically to a condition monitoring device and its usage method. Background Technology

[0002] With the continuous development of aircraft, other aerospace vehicles, and spacecraft, the demand for improved energy conversion efficiency in related power distribution equipment is constantly increasing. This leads to increasingly stringent technical requirements for power distribution equipment, such as reducing its size and weight, and improving the reliability of electrical systems. Simultaneously, the increasingly complex and variable application environments of products are placing ever-strengthening demands on their resistance to vibration, noise, damp heat, salt spray, grease, and acidic atmospheres. Furthermore, to achieve product condition monitoring, products need to possess condition monitoring capabilities and be able to connect and communicate with external monitoring lines.

[0003] Patent document CN 106356258 B discloses a parallel control circuit breaker. This circuit breaker uses an external parallel connection method to achieve parallel control of the circuit. However, in this patent, the parallel control method mainly connects multiple single-phase circuit control products externally to achieve parallel control, resulting in a larger product size compared to internal parallel control methods. Furthermore, the product in this patent lacks temperature compensation capabilities, limiting its applicable temperature range and failing to meet the demands of varying environments. Additionally, the product in this patent lacks condition monitoring functionality, making it impossible to monitor product status.

[0004] US Patent No. 8008585B2 discloses a parallel control switch. This patented product includes a temperature compensation mechanism, a button structure, a connecting assembly, and a bridging device. The connecting assembly connects the electrical switch assembly, and the bridging device connects the braking device. The product has temperature compensation capability, but the parallel control method is still a single-phase external parallel connection. Furthermore, this patented product also lacks status monitoring functionality and cannot achieve product status monitoring.

[0005] Patent CN110931319B discloses a parallel control circuit breaker. This patented product features temperature compensation, enabling it to operate in complex temperature environments. Furthermore, it employs an internal parallel control method, resulting in a lighter size and weight. However, the product lacks condition monitoring capabilities, making it impossible to monitor product status. Additionally, information regarding the product's performance in areas such as vibration resistance, noise resistance, damp heat resistance, salt spray resistance, grease resistance, and acidic atmosphere resistance cannot be found in the patent text.

[0006] To improve the resistance of condition monitoring devices to damp heat, salt spray, grease, and acidic atmospheres, the common approach is to add protective covers or corrugated pipe structures to the product buttons or operating positions. Both methods increase the structural complexity of the buttons or operating positions, and the position indication function is not obvious, making it difficult to observe the product status position.

[0007] To improve the vibration and noise resistance of the condition monitoring device, it is necessary to optimize the design of the product's operating structure, increase the contact pressure of the contacts, and improve the stability of the product's operating structure.

[0008] To achieve product status monitoring, a modular design approach is needed, specifically for auxiliary contact functionality. Currently, common position detection solutions fall into two main categories: one involves adding sensors to commonly used electromagnetic relays, circuit breakers, or contactors to achieve position detection; the other involves adding auxiliary contact modules to the product, using mechanical auxiliary contact modules to achieve position detection. Sensor-based detection involves adding related electronic detection mechanisms and circuits while retaining the original device structure, inevitably increasing the product's size and weight. Furthermore, this design lacks integration and structural versatility, increasing redundant design across different products and wasting design resources. Mechanical modules offer versatility and standardization with high reliability; however, traditional mechanical modules present challenges in component manufacturing and require high precision during assembly. Therefore, designing a position detection module that is easy to assemble, manufacture, and highly reliable is crucial. Summary of the Invention

[0009] Purpose of the invention: It is of great importance to design a parallel condition monitoring device that is small in size, light in weight, highly reliable, has condition detection function and clear condition indication, as there is a huge demand for such a parallel condition monitoring device in the aerospace or aviation fields.

[0010] Technical solution:

[0011] In a first aspect, a state monitoring device is provided, comprising: a motion control component, a power control component, a position detection component, a transmission component, a support component, and a drive compensation component, wherein the motion control component, power control component, position detection component, transmission component, and drive compensation component constitute the device via the support component; wherein...

[0012] The motion control component is used to control the on / off state of the conduction component and the power control component, and to provide a status indication of the device.

[0013] The power control component is used to achieve line conduction and power control;

[0014] The position detection component is used to detect the position of the main contact on the conductive component in order to detect the status of the device;

[0015] The conductive component is used to enable the conduction and disconnection of the load line current;

[0016] The drive compensation component is used to control the hook position of the same motion control component by synchronizing the thermal deformation of the same power control component;

[0017] In the closed state, the motion control component controls the conduction component to conduct with the power control component, and simultaneously the motion control component engages with the drive compensation component, while the conduction component disengages from the position detection component, thereby achieving the conduction of the external load line; in the open state, the drive compensation component disengages from the motion control component, causing the control conduction component to disconnect from the power control component, achieving the disconnection of the external load line, and the control conduction component contacts the position detection component, which then detects the position of the main contact; or

[0018] In the closed state, the motion control component controls the conduction component and the power control component to conduct, and at the same time, the motion control component is engaged with the drive compensation component, the conduction component is in contact with the position detection component, and the position detection component realizes the position detection of the main contact and realizes the conduction of the external load line; in the open state, the drive compensation component is disengaged from the motion control component, so that the control conduction component is disconnected from the power control component, realizing the disconnection of the external load line, and the control conduction component is disconnected from the position detection component.

[0019] Secondly, a method for using a condition monitoring device is provided, the method comprising:

[0020] When the motion control component is pressed, the transmission component and the power control component are connected. At the same time, the motion control component and the drive compensation component are engaged, the transmission component and the position detection component are separated, and the external load circuit is connected.

[0021] When the external current exceeds a certain threshold, the power control component pushes the drive compensation component to disengage from the motion control component. The motion control component then causes the conduction component to separate from the power control component, and the conduction component contacts the position detection component, thus disconnecting the external load line.

[0022] Beneficial Effects: This condition monitoring device adopts an integrated design, combining switching devices, protective devices, and position detection functions. Through optimized component layout, it reduces product weight and size while providing parallel circuit continuity, disconnection, and overload protection, as well as body position detection and indication. The device features an innovative protective structure that prevents liquids, gases, and microparticles from entering the product, allowing it to be used near engines, transmissions, and fuel tanks. This protective mechanism also makes the product suitable for marine or dusty environments. The temperature compensation design allows the product to operate over a wide temperature range, improving its stability under different temperature conditions. Furthermore, the optimized hinge structure of the operating mechanism allows the product to withstand high-frequency operating environments with vibration and noise. The combination of these design features significantly expands the product's application scenarios and improves its environmental adaptability. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The implementation and use of specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, it should be understood that the specific embodiments described are merely illustrative of particular ways of implementing and using the present invention, and are not intended to limit the scope of the present invention.

[0051] A status monitoring device is provided, comprising: a motion control component, a power control component, a position detection component, a conduction component, a support component, and a drive compensation component. The motion control component, power control component, position detection component, conduction component, and drive compensation component are configured into the device via the support component. The motion control component controls the on / off state of the conduction component and the power control component, providing a status indication of the device. The power control component enables circuit continuity and power control. The position detection component detects the position of the main contacts on the conduction component to detect the device status. The conduction component enables the conduction and disconnection of the load circuit current. The drive compensation component controls the hook position of the motion control component based on the synchronization of thermal deformation of the power control component and the power control component.

[0052] In the first coordination logic, in the closed state, the motion control component controls the conduction component to conduct with the power control component, and at the same time, the motion control component engages with the drive compensation component, while the conduction component disengages from the position detection component, thereby achieving the conduction of the external load line; in the open state, the drive compensation component disengages from the motion control component, the motion control component moves upward, causing the control conduction component to disconnect from the power control component, achieving the disconnection of the external load line, and the control conduction component contacts the position detection component, which performs position detection of the main contact.

[0053] In the second coordination logic, in the closed state, the motion control component controls the conduction component and the power control component to conduct, and at the same time, the motion control component is engaged with the drive compensation component, the conduction component is in contact with the position detection component, and the position detection component realizes the position detection of the main contact and realizes the conduction of the external load line; in the open state, the drive compensation component is disengaged from the motion control component, the motion control component moves upward, so that the control conduction component is disconnected from the power control component, realizing the disconnection of the external load line, and the control conduction component is disconnected from the position detection component.

[0054] In a specific embodiment, the motion control component is installed in the middle of the inner cavity of the support component. Its upper end extends out from the center hole of the upper end face of the support component and is fixed on the support component. Its lower end contacts the transmission component and works with the transmission component to perform reciprocating motion. It is installed on the bottom surface of the inner cavity of the support component.

[0055] In this condition monitoring device, the power control component is installed in the lower part of the inner cavity of the support component, with its upper end extending into one side of the inner cavity of the support component to cooperate with the drive compensation component, and its lower end located in the lower part of the support component to connect with the external load line.

[0056] In this status monitoring device, the position detection component is installed on the inner wall of the support component. The detection ends of the position detection component extend outward and inward from the side wall respectively. The detection end extending inward is connected to the conduction component in accordance with the above reciprocating motion. The output end of the position detection component extends out of the side wall of the support component and is connected to the detection line.

[0057] In this status monitoring device, the transmission component is installed in the inner cavity of the support component, its upper end cooperates with the motion control component, and its lower end cooperates with the power control component during the reciprocating motion of the motion control component;

[0058] In this condition monitoring device, the drive compensation component is installed on one side of the inner cavity of the support component. Its upper end cooperates with the support component, and the drive compensation component can rotate around the support component. Its lower end cooperates with the upper end of the power control component.

[0059] In a specific embodiment, the product employs an internal parallel control method, where the conductive components and power control components are connected and disconnected within the product. The motion control component controls the movement of the conductive components, enabling a reduction in product size and weight. Additionally, the product includes a position detection component for status monitoring.

[0060] The aforementioned motion control component includes a pull button, an indicator ring, a positioning sleeve, an insulating sleeve, a motion control mechanism, and a spring. The pull button is located at the end of the motion control component. The lower end of the pull button passes through the indicator ring, the positioning sleeve, and the insulating sleeve and is connected to the motion control mechanism. The pull button is used to manually control the connection and disconnection of the entire device. The indicator ring is located between the pull button and the motion control mechanism. The indicator ring is used to indicate the connection and disconnection status of the device. The indicator ring is fixedly connected to the pull button and moves back and forth with the pull button. When the product is connected, the indicator ring is embedded in the positioning sleeve. When the product is disconnected, the indicator ring is exposed in the positioning sleeve. The positioning sleeve is installed on the upper end of the upper housing and cooperates with the positioning plate to define the installation position of the entire product. The insulating sleeve is installed between the indicator ring and the positioning sleeve. The relative position between the insulating sleeve and the positioning sleeve is fixed. The insulating sleeve has the function of sealing and insulating the internal structure of the device from the external environment.

[0061] The entire device's requirements for resistance to damp heat, salt spray, grease, and acidic atmosphere can be achieved through the interaction of the insulating sleeve with the pull button, indicator ring, and positioning sleeve. The insulating sleeve can prevent external liquids, moisture, salt spray, or other grease particles from entering the product, thereby preventing damage or corrosion to the internal parts of the product.

[0062] The aforementioned motion control component also includes a motion control mechanism. The motion control mechanism can control the connection and disconnection of the conduction component and the power control component when the pull button is activated. At the same time, when an overload current occurs in the power control component, the conduction component is disconnected from the power control component. The conduction component can drive the motion control mechanism to change position, which in turn causes the pull button and the indicator ring to change position, causing the indicator ring to disengage from the positioning sleeve.

[0063] One end of the spring is attached to the motion control mechanism, and the other end is attached to the transmission component. This is used to separate the power control component from the transmission component when the product is disconnected.

[0064] Through the above-described process, the product can achieve manual on / off switching and overload control of parallel circuits.

[0065] The aforementioned power control components include a mounting base, sensitive elements, a terminal block assembly, and a fastening assembly. The mounting base is used to mount the sensitive elements of each phase and the terminal block assembly, and to provide insulation between different components. The sensitive elements are evenly distributed on the upper part of the mounting base and are used to conduct multi-line load current. When one or more phases of the multi-line load current exceed a certain limit, the sensitive element of the corresponding phase undergoes thermal deformation. The terminal block assembly is evenly distributed on the upper part of the mounting base and is used to conduct multi-line load current.

[0066] Preferably, the sensitive element includes a busbar, a bent plate, a heat insulation sheet, a conductive sheet, a bimetallic component, a stationary contact component, and a fixing component. One end of the busbar has a threaded hole for installing an external wire, and its other end mates with the long end of the bent plate. The first fixed mating end of the bimetallic component, the conductive sheet, and the bent plate are abutted together at the bent position to form a first integral unit. The base of the first integral unit is installed at the fixed end of the busbar. The threaded end of the busbar has a threaded hole for installing an external wire. The second fixed mating end of the bimetallic component, the conductive sheet, and the bent plate are abutted together at the bent position to form a second integral unit. The base of the second integral unit is installed at the fixed end of the stationary contact component. The heat insulation sheet is sandwiched between the non-base position of the conductive sheet and the non-base position of the bent plate to isolate heat between the bent plate and the bimetallic component. The bimetallic component is used to conduct load current.

[0067] More preferably, when the load current exceeds a certain limit, the bimetallic component undergoes thermal deformation, with bent plates connected to both ends of its bottom. The stationary contact component is used to make contact with the conductive component for conduction. The fixing component fixes the busbar, bent plate, conductive sheet, and bimetallic component together. The fixing component is also used to fix the parts in the sensitive element to ensure the relative position of each part.

[0068] More preferably, the sensitive element in the power control component can be selected from stacked bimetallic materials with different sensitivities according to different load circuit requirements, so as to achieve conduction and protection of different currents between multiple phases;

[0069] The aforementioned conductive components include a conductive base, a moving contact component, a hook support plate, a monitoring drive plate, and fasteners. The conductive base is used to install the moving contact component, the hook support plate, the monitoring drive plate, and the fasteners, and is driven by a motion control component to achieve reciprocating motion. The conductive base also provides insulation between moving contact components of different phases. The moving contact component is responsible for conducting contact with the stationary contact component and the terminal block component in the sensitive element, and for connecting and disconnecting the load line current. The moving contact component is installed on one side of the bottom of the conductive base. The hook support plate is responsible for cooperating with the support component to provide a rapid connection effect between the conductive component and the power control component, and to realize the relatively fixed position of the conductive component in the support component. The hook support plate is installed on the upper end of the conductive base, on the side opposite to the moving contact component.

[0070] More preferably, the monitoring drive board is responsible for cooperating with the position detection component to drive or transmit the monitoring device in the position detection component, thereby realizing the position monitoring of the control device. The monitoring drive board is installed on the other side of the upper end of the transmission base.

[0071] Preferably, the moving contact component includes a moving piece 421, a moving contact 422, a moving shaft 423, a second spring 424, and a limiting ring 425. The moving piece is used to transmit the conducting current of the moving contacts at both ends and to fix the position of the moving contacts. It can move up and down along the moving shaft. The moving piece is installed at the bottom of the moving contact component. The moving shaft installs the entire moving contact component at a specific position on the conductive seat. The second spring is used to provide contact pressure between the moving contact component and the stationary contact component and the terminal block component. It passes through the moving shaft in the middle, and one end cooperates with the moving piece and the conductive seat. The limiting ring is used to limit the position of the moving shaft on the conductive seat.

[0072] The aforementioned drive compensation component includes a mounting base 61, a compensation bimetallic strip 62, a calibration spring 63, a hook plate 64, an adjusting screw 65, a rivet 66, and a spring 67. The mounting base is used to install the compensation bimetallic strip, the calibration spring, the hook plate, and the spring, and to transmit the force values ​​between the parts. The compensation bimetallic strip is used for temperature compensation of the product. When the product temperature changes, the shape of the compensation bimetallic strip changes, which is used to change the fit relationship between the drive compensation component and the edge phase bimetallic component in the sensitive element. It is installed on one side of both ends of the mounting base. The calibration spring is used to adjust the position of the compensation bimetallic strip to avoid excessive deformation of the compensation bimetallic strip. The spring is used to control excessive deformation of the hook plate and control the position of the entire drive compensation component, ensuring the fit relationship between the drive compensation component and the power control component and the motion control component. The spring is installed between the hook plate and the mating end of the bimetallic strip and the mounting base. The adjusting screw is installed on the ends of the compensation bimetallic strip and the hook plate respectively, and is used to adjust the fit clearance between the compensation bimetallic strip, the hook plate, and the sensitive element.

[0073] Preferably, the hook plate has an inverted "U" shaped structure, with its upper middle part installed on the mounting base. The locking end cooperates with the motion control component, and the temperature control end cooperates with the middle phase bimetallic component. The temperature control end is used to compensate for the temperature of the product. When the product temperature changes, the shape of the temperature control end changes, which is used to change the cooperation relationship between the drive compensation component and the middle phase bimetallic component of the sensitive element.

[0074] More preferably, the bimetallic compensation component and the hook plate in the drive compensation component have a temperature compensation function. When the environment in which the product is used changes, the cooperation between the two parts and the power control component in the product is used to adjust the deformation of the bimetallic component in the power control component due to temperature changes, thereby improving the overall reliability and stability of the product under different temperature conditions.

[0075] When the ambient temperature around the product increases, the sensitive element bends and deforms due to the temperature rise, giving the drive compensation component a rotational force; at the same time, the compensation bimetal and the hook plate also deform in the opposite direction, giving the power control component a reverse force; the reverse force cancels or partially cancels the rotational force, thereby reducing the amount of disengagement between the motion control mechanism and the locking end generated by the rotational force, so that the hook amount is kept within a certain range.

[0076] When the ambient temperature around the product decreases, the sensitive element undergoes reverse bending deformation due to the temperature drop, reducing the rotational force on the drive compensation component. Similarly, the reverse force exerted on the power control component by the compensation bimetal and the hook plate also decreases. The contact force between the power control component and the drive compensation component decreases, and the alignment spring and the spring will provide a reverse force compensation to the compensation bimetal and the hook plate under the action of their own restoring force. This reduces the amount of disengagement between the motion control mechanism and the locking end generated by the rotational force, keeping the hook amount within a certain range.

[0077] In this invention, the position detection component can adopt a spring probe structure, which includes a base 31A, a probe 32A, and a standard part 33A. The probe is fixed on the base, one end of the probe extends out of the base and is connected to the standard part, and the other end extends out of the base and cooperates with the monitoring drive plate. When the monitoring drive plate is in contact with the two probes, the position detection component is turned on; when the monitoring drive plate is separated from the two probes, the position detection component is turned off.

[0078] In this invention, the position detection component structure is not limited to a spring probe structure or a microswitch structure. Those skilled in the art can make various changes and modifications to the various features and combinations of features not explicitly shown herein.

[0079] The aforementioned support components include an upper housing, a positioning plate, an insulating plate, a retaining mechanism, and fasteners. The upper housing is responsible for installing the internal mating parts of the product and is located in the middle of the entire product. The positioning plate is responsible for defining the installation position of the entire product and is installed on the upper end face of the upper housing. The insulating plate serves to insulate the positioning plate from the entire product and is installed between the positioning plate and the upper housing. The retaining mechanism is used to control the product connection process, ensuring rapid product connection and preventing arcing between contacts during slow connection. It is installed on one side inside the upper housing.

[0080] Preferably, the positioning plate includes a mounting hole and a positioning pin. The mounting hole is located in the middle of the positioning plate and is responsible for mounting the motion control component and maintaining the relative position of the entire motion control component in the product. The positioning pin is responsible for limiting the position and orientation of the product during use and is located at the end of the positioning plate.

[0081] Preferably, the retaining mechanism includes a return spring, a pin, and a force-applying component. The return spring provides rotational torque to the force-applying component, and the pin passes through the return spring and the force-applying component to fix both to one side of the upper end inside the upper housing.

[0082] More preferably, the force-applying component includes washers, connecting rods, tie rods, and springs. The springs are fitted between the connecting rods and tie rods, providing the force for the connecting rods and tie rods to restore and fix their positions. Washers are installed at both ends of the springs, responsible for constraining the spring's position and pressure. The connecting rods are located on both sides of the tie rods, with one end engaging with a pin and the other end engaging with a hook support plate of the transmission component. The tie rods are located in the middle of the force-applying component, with one end engaging with a pin and the other end engaging with a hook support plate of the transmission component.

[0083] When the entire product is in the disconnected state, the pull rod engages with the hook support plate, and the connecting rod disengages from the hook support plate.

[0084] When the entire product is in the connected state, the connecting rod engages with the hook support plate, and the pull rod disengages from the hook support plate.

[0085] The status monitoring device of this invention has functions such as multi-phase line parallel switching, power control, position detection and position indication. It reduces redundant structural design and use, has high overall reliability, and features small size and light weight. Through optimized design, this device has functions such as vibration resistance, noise resistance, damp heat resistance, salt spray resistance, grease resistance and acid atmosphere resistance, which can meet the application of products in various complex environments.

[0086] Figure 1 The diagram shows a partial cross-sectional view of the overall structure of a status monitoring device in its on / off state. According to an embodiment of the present invention, the status monitoring device includes: a motion control component 1, a power control component 2, a position detection component 3, a conduction component 4, a support component 5, and a drive compensation component 6. The motion control component 1, power control component 2, position detection component 3, conduction component 4, and drive compensation component 6 are connected by the support component 5 to form the device. The motion control component 1 controls the connection and disconnection between the conduction component 4 and the power control component 2, providing a status indication of the device. The power control component 2 enables line continuity and power control. The position detection component 3 detects the position of the main contacts on the conduction component 4 to detect the device status.

[0087] The conductive component 4 is used to realize the conduction and disconnection of the load line current; the drive compensation component 6 is used to control the hook position of the motion control component 1 by synchronizing the thermal deformation of the same power control component 2.

[0088] See Figure 3-5 In this embodiment, the motion control component 1 is installed in the middle of the inner cavity of the support component 5, and the motion control component 1 contacts the conduction component 4, and performs reciprocating motion in cooperation with the conduction component 4; the upper end of the power control component 2 extends into one side of the inner cavity of the support component 5, and cooperates with the drive compensation component 6, while its lower end is exposed below the support component 5 for connection with external load lines; the position detection component 3 is installed on the side wall of the inner cavity of the support component 5, and the detection end contacts or separates from the conduction component 4 as it reciprocates; the conduction component 4 is installed in the inner cavity of the support component 5, with its upper end cooperating with the motion control component 1, and its lower end cooperating with the power control component 2 as it reciprocates; the drive compensation component 6 is installed on one side of the inner cavity of the support component 5, with its upper end cooperating with the support component 5, and the drive compensation component 6 can rotate around the support component 5, while its lower end contacts and cooperates with the power control component 2, giving each other a counterforce.

[0089] For detailed work procedures, please refer to [link / reference]. Figure 4 , Figure 7 , Figure 8As shown, it can be summarized as follows: When the pull button 11 in the motion control component 1 moves downward along the axial direction of the motion control component 1, the pull button 11 drives the motion control mechanism 15 to move downward, causing the control transmission component 4 and the power control component 2 to gradually approach each other. At this time, the transmission component 4 cooperates with the holding mechanism 54 in the support component 5. The spring 5434 in the holding mechanism 54 inhibits the contact between the control transmission component 4 and the power control component 2. When the pressure in the pull button 11 reaches a certain force value, the spring 5434 in the holding mechanism 54 fails to prevent the control transmission component 4 from contacting the power control component 2. Figure 1 , Figure 2 and Figure 5 The control and conduction component 4 and the power control component 2 are momentarily connected, putting the product in the connected state. At this time, the moving contact 422 in the moving contact component 42 contacts the corresponding stationary contact component 226 and the terminal block component 23. Figure 5 This ensures that the current in each phase is in the same state. Due to the cooperation between the motion control component 1 and the support component 5, the second springs 424 of each phase in the conduction component 4 are in a compressed state, thereby ensuring the contact pressure between the moving and stationary contacts in the device. Figure 6 When the product is in the ON state, the motion control mechanism 15 contacts the bottom of the locking end 641 of the hook plate 64 in the drive compensation component 6. The relative positions of the parts in the entire motion control mechanism 15 are in a locked state, and at the same time, with the help of the relevant cooperation relationship between the compensation bimetal 62 and the upper housing 51, such as... Figure 15 This ensures that the position of the motion control components remains unchanged.

[0090] When the entire device is subjected to high-frequency environments such as vibration and noise, the interaction between the alignment spring 63, spring 5434, return spring 541 and the first spring 16 in the motion control component 1 keeps the relative engagement position of the motion control mechanism 15 and the locking end 641 within a certain range, and ensures that the bottom of the motion control mechanism 15 and the locking end 641 are in contact, thereby ensuring the connection state of the entire product.

[0091] like Figure 5 As shown, during the product connection process, the heat-insulating sheet 2253 in the sensitive element 22 contacts the adjusting screw 65 to ensure that the sensitive element 22 and the drive compensation component 6 are in a relatively static state.

[0092] Under the first coordination logic, the position detection component 3 is separated from the monitoring drive board 44 in the conduction component (4), such as Figure 5 As shown. And the indicator ring 12 is fully embedded in the positioning sleeve 13, wherein, Figure 4 , Figure 5 , Figure 17 , Figure 18 , Figure 22 and Figure 23 The state diagrams are all under the first type of coordination logic. It is understood that in some other embodiments, i.e., under the second type of coordination logic, when the control transmission component 4 is connected to the power control component 2, the position detection component (3) is connected to the monitoring drive board 44 in the transmission component 4, such as... Figure 25 As shown. At this time, the indicator ring 12 is fully embedded in the positioning sleeve 13.

[0093] The temperature compensation process of the status monitoring device of the present invention when it is turned on can be summarized as follows: when the ambient temperature around the product changes, it is specifically manifested as a decrease or increase in temperature.

[0094] Specifically, when the ambient temperature around the product increases, the sensitive element 22 bends and deforms due to the temperature change, which in turn moves the heat-insulating plate 2253 toward the adjusting screw 65. This causes the adjusting screw 65 to change position, and in turn, the adjusting screw 65 causes the entire drive compensation component 6 to rotate around the upper housing 51. This movement causes a change in the relative engagement position between the motion control mechanism 15 and the locking end 641, reducing the engagement amount between the motion control mechanism 15 and the locking end 641. In this invention, when the sensitive element 22 bends and deforms due to the ambient temperature change, the compensation bimetal 62 and the locking plate 64 also deform, causing the adjusting screw 65 to push against the heat-insulating plate 2253. This suppresses the reduction in the engagement amount between the motion control mechanism 15 and the locking end 641 caused by the deformation of the sensitive element 22, keeping the engagement amount within a certain range. This reduces the reduction in engagement amount caused by temperature changes.

[0095] The force change in this process can be represented as follows: when the ambient temperature around the product increases, the sensitive element 22 bends and deforms due to the temperature rise, giving the drive compensation component 6 a rotational force; at the same time, the compensation bimetal 62 and the hook plate 64 also deform in the opposite direction, giving the power control component 2 a reverse force; the reverse force cancels or partially cancels the rotational force, thereby reducing the amount of disengagement between the motion control mechanism 15 and the locking end 641 generated by the rotational force.

[0096] Specifically, when the ambient temperature around the product decreases, the sensitive element 22 bends and deforms due to the temperature change, causing the heat-insulating sheet 2253 to move away from the adjusting screw 65. At this time, the spring 67 drives the adjusting screw 65 to engage with the heat-insulating sheet 2253. The adjusting spring 63 and the spring 67 then drive the entire drive compensation component 6 to rotate around the upper housing 51. This movement causes a change in the relative engagement position between the motion control mechanism 15 and the locking end 641. In this invention, when the ambient temperature decreases, the compensation bimetal 62 and the hook plate 64 also deform, causing the adjusting screw 65 to move away from the heat-insulating sheet 2253. The resulting force can partially eliminate the increase in the product hook amount caused by the deformation of the spring 67, keeping the hook amount within a certain range. This reduces the impact of temperature decrease on the hook amount. The fixing clip 2252 is used to fix the laminated bimetal 2251 and the heat-insulating sheet 2253 together.

[0097] The force change in this process can be expressed as follows: when the ambient temperature of the product decreases, the sensitive element 22 undergoes reverse bending deformation due to the temperature decrease, which reduces the rotational force given to the drive compensation component 6. Similarly, the reverse force given to the power control component 2 by the compensation bimetal 62 and the hook plate 64 also decreases. The contact force between the power control component 2 and the drive compensation component 6 decreases. Under the action of their own restoring force, the alignment spring 63 and the spring 67 will give the compensation bimetal (62) and the hook plate 64 a reverse force compensation force.

[0098] The overcurrent protection disconnection process of the state monitoring device of the present invention in the on state can be summarized as follows:

[0099] When the current flowing through any one or more components of the product exceeds a specified value for a certain period of time, the temperature of the interphase sensitive elements 22 changes due to the current, causing them to bend and deform. This causes the heat-insulating plate 2253 to move towards the adjusting screw 65, changing its position. The adjusting screw 65 then causes the entire drive compensation component 6 to rotate around the upper housing 51. At this time, due to the time difference in temperature transmission, the deformation of the compensation bimetallic strip 62 and the latch plate 64 is small or nonexistent, preventing the adjusting screw 65 from pushing against the heat-insulating plate 2253. Therefore, the effect of reducing the latching amount of the motion control mechanism 15 and the latching end 641 caused by the deformation of the sensitive element 22 cannot be achieved. At this point, the relative engagement position of the motion control mechanism 15 and the latching end 641 changes, gradually reducing the latching amount until it disengages. Figure 4 , Figure 7 , Figure 8 and Figure 18 .

[0100] When the motion control mechanism 15 is disrupted from the latching state of the locking end 641, the control transmission component 4 separates from the power control component 2, causing the product to change from the connected state to the disconnected state. At this time, the moving contact 422 in the moving contact component 42 simultaneously separates from the corresponding mating stationary contact component 226 and terminal block component 23, causing all multi-phase circuits to change from the connected state to the disconnected state. Figure 8 and Figure 18 .

[0101] At the same time, the position detection component 3 contacts the monitoring drive board 44 in the transmission component 4, and the position detection component 3 can detect the disconnection state of the transmission component 4. Figure 4 and Figure 18 .

[0102] At this time, the indicator ring 12 is axially disengaged from the positioning sleeve 13. Since the indicating product is in an open state, such as Figure 8 .

[0103] In some embodiments, the disconnection process of the status monitoring device of the present invention can also be manual, as follows:

[0104] When an external force pulls the pull button 11 in the motion control component 1 upward along the axis of the motion control component 1, the pull button 11 drives the motion control mechanism 15 upward. The relative engagement position of the motion control mechanism 15 and the locking end 641 changes, reducing the engagement amount between the motion control mechanism 15 and the locking end 641. As the engagement amount between the motion control mechanism 15 and the locking end 641 gradually decreases until it disengages, such as... Figure 7 As shown.

[0105] When the motion control mechanism 15 is disrupted from the latching state of the locking end 641, the control transmission component 4 separates from the power control component 2, causing the product to change from the connected state to the disconnected state. At this time, the moving contact 422 in the moving contact component 42 simultaneously separates from the corresponding mating stationary contact component 226 and terminal block component 23, causing all multi-phase circuits to change from the connected state to the disconnected state. Figure 8 and Figure 18 .

[0106] At the same time, the position detection component 3 contacts the monitoring drive plate 44 in the transmission component 4, and the indicator ring 12 is axially dislodged from the positioning sleeve 13, indicating that the product is in a disconnected state.
