Description

Condition monitoring device and method of using the same Technical Field

[0001] The present invention relates to an electrical product, and in particular to a state monitoring device and a method of using the same. Background Art

[0002] The continuous development of aircraft, other aircraft, and spacecraft is driving the need for improved energy conversion efficiency in related power distribution equipment. This has led to increasing technical requirements for reducing the size and weight of these equipment and improving the reliability of electrical systems. Furthermore, the complex and ever-changing application environments are increasing the requirements for product resistance to vibration, noise, humidity, heat, salt spray, grease, and acidic atmospheres. Furthermore, to monitor product status, products must have status monitoring capabilities that can communicate with external monitoring circuits.

[0003] Patent number CN 106356258 B describes a parallel-controlled circuit breaker that uses an external parallel connection method to achieve parallel control of circuits. However, the patent describes a parallel control method that primarily connects multiple single-phase circuit control products in parallel externally. This method results in a larger product than an internal parallel control method. Furthermore, the patent also lacks temperature compensation capabilities, resulting in a low temperature range and insufficient compliance for changing environments. Furthermore, the patent also lacks a status monitoring function, making it impossible to monitor product status.

[0004] Patent No. US8008585B2 describes a parallel control switch. The product in this patent features a temperature compensation mechanism, a button structure, a connecting assembly, and a bridge device. The connecting assembly connects the electrical switch assembly, and the bridge device connects the brake device. While the product has temperature compensation capabilities, the parallel control method is similar to external parallel connection of single-phase products. Furthermore, this patent also lacks a status monitoring function, making it impossible to implement product status monitoring.

[0005] Patent number CN110931319B describes a parallel-controlled circuit breaker. The product in this patent features temperature compensation, making it suitable for environments with complex temperature fluctuations. It also utilizes internal parallel control, resulting in a lightweight and compact design. However, the patent lacks a condition monitoring function, making it impossible to implement product status monitoring. Furthermore, the patent text provides no information regarding the product's resistance to vibration, noise, humidity, heat, salt spray, grease, and acidic atmospheres.

[0006] In order to improve the performance of the status monitoring device in terms of resistance to moisture and heat, salt spray, grease and acidic atmosphere, a common method is to add a protective cover or a bellows structure to the product button or operation position. Both methods will increase the structure of the button or operation position, and the position indication function is not obvious, making it difficult to observe the product status position.

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

[0008] To achieve product status monitoring, a modular design approach is required to implement this functionality, specifically the auxiliary contact function. Currently, there are two common position detection solutions. One involves adding sensors to conventional electromagnetic relays, circuit breakers, or contactors to detect product position. The other involves adding auxiliary contact modules to the product, implementing this function through a mechanical auxiliary contact module. Sensor detection primarily involves retaining the original device structure while adding the relevant electronic detection mechanisms and circuitry, inevitably increasing the product's size and weight. Furthermore, this design approach lacks integration and structural versatility, leading to redundant, repetitive design across different products and a waste of design resources. Mechanical modules offer universalization and serialization, as well as high reliability. However, traditional mechanical modules present difficulties in component processing and require high precision during assembly. Therefore, it is crucial to design a position detection module that is easy to assemble, convenient to process, and highly reliable.

[0009] Summary of the Invention

[0010] Purpose of the invention: It is particularly important to design a parallel state monitoring device that is small in size, light in weight, highly reliable, has a state detection function and has obvious state indication.

[0023] Beneficial effects: The status monitoring device adopts an integrated design feature, combining switching electrical appliances, protective electrical appliances and position detection functions together. Through the optimized layout of components, the weight and volume of the product are reduced, and at the same time, the parallel circuit can be turned on, off and overload protected, and the main body position detection and position indication functions can be realized.

[0050] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0051] DETAILED DESCRIPTION

[0052] The following describes in detail the implementation and use of the specific embodiments of the present invention with reference to the accompanying drawings. However, it should be understood that the specific embodiments described are only exemplary of specific ways to implement and use the present invention, and are not intended to limit the scope of the present invention.

[0053] Provided is a state monitoring device, comprising: a motion control component, a power control component, a position detection component, a conduction component, a support component, and a drive compensation component, wherein the motion control component, the power control component, the position detection component, the conduction component, and the drive compensation component constitute the device through the support component; the motion control component is used to control the on / off connection of the conduction component and the power control component, and provide an indication of the device state; the power control component is used to achieve line conduction and power control; the position detection component is used to detect the position of a main contact on the conduction component to detect the device state; the conduction component is used to achieve on / off connection of a load circuit current; and the drive compensation component is used to control the hook position of the motion control component by synchronizing thermal deformation of the conduction component and the power control component.

[0054] Among them, the first coordination logic is that 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 hooked with the drive compensation component, and the conduction component is separated from the position detection component, thereby realizing the conduction of the external load circuit; in the disconnected state, the drive compensation component is disconnected from the motion control component, and 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 circuit, and the control conduction component contacts the position detection component, and the position detection component realizes the position detection of the main contact;

[0055] The second coordination logic is that in the closed state, the motion control component controls the conduction component and the power control component to be connected, and at the same time, the motion control component is hooked with the drive compensation component, and the conduction component is in contact with the position detection component. The position detection component realizes the position detection of the main contact and realizes the conduction of the external load circuit; in the disconnected state, the drive compensation component is disengaged from the motion control component, and 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 circuit, and the control conduction component is disconnected from the position detection component.

[0056] In a specific embodiment, the motion control component is installed in the middle of the inner cavity of the support component, with its upper end extending from the central hole of the upper end surface of the support component and fixed to the support component, and its lower end contacts the conductive component, cooperates with the conductive component to perform reciprocating motion, and is installed on the bottom surface of the inner cavity of the support component;

[0057] In the 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 and cooperating with the drive compensation component, and its lower end is located at the lower part of the support component and connected to the external load circuit;

[0058] In the condition monitoring device, a position detection component is mounted on the side wall of the inner cavity of the support component, and detection ends of the position detection component extend outward and inward of the side wall, respectively. The inwardly extending detection end is electrically connected to the conductive component in conjunction with the 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 circuit.

[0059] In this state monitoring device, the conducting component is installed in the inner cavity of the supporting component, the upper end of the conducting component cooperates with the motion control component, and the lower end cooperates with the power control component during the reciprocating motion of the motion control component;

[0060] In the condition monitoring device, the drive compensation component is installed on one side of the inner cavity of the support component, and its upper end cooperates with the support component. The drive compensation component can rotate around the support component, and its lower end cooperates with the upper end of the power control component.

[0061] In a specific embodiment, the product utilizes an internal parallel control method, where the conductive components and power control components are connected and disconnected internally. A motion control component controls the motion of the conductive components, reducing the size and weight of the product. Furthermore, an internal position detection component enables status monitoring.

[0062] The above-mentioned motion control component includes a pull-out button, an indicator ring, a positioning sleeve, an insulating sleeve, a motion control mechanism and a spring. The pull-out button is at the end of the motion control component. The lower end of the pull-out button passes through the indicator ring, the positioning sleeve, the insulating sleeve and is combined with the motion control mechanism. The pull-out button is used to manually control the connection and disconnection of the entire device. The indicator ring is arranged between the pull-out 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 fixed to the pull-out button. The indicator ring moves back and forth with the pull-out 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 from the positioning sleeve; the positioning sleeve is installed at the upper end of the upper shell and cooperates with the positioning piece to limit 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 and the external environment.

[0063] The requirements of the entire device for resistance to moisture and heat, salt spray, grease and acidic atmosphere can be achieved through the cooperation 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 interior of the product, thereby avoiding damage or corrosion to the internal parts of the product.

[0064] The above-mentioned motion control component also includes a motion control mechanism, which can control the conduction component to be connected and disconnected with the power control component under the action of the pull button; at the same time, when an overload current occurs in the power control component, the conduction component is controlled to be disconnected and connected with the power control component, and the control conduction component can drive the motion control mechanism to change its position, and then the motion control mechanism drives the pull button and the indicator ring to change their positions, so that the indicator ring falls out of the positioning sleeve.

[0065] One end of the spring is hung on the motion control mechanism, and the other end is hung on the conductive component, and is used to separate the power control component from the conductive component when the product is disconnected.

[0066] Through the above-mentioned action process, the product can realize manual on / off and overload control of parallel lines.

[0067] The power control component includes a fixed base component, a sensitive element, a terminal block component, and a fastening assembly; the fixed base component is used to mount the sensitive elements and terminal block components of each phase and provide insulation between different components; the sensitive elements are uniformly distributed on the upper portion of the fixed base component and are used to conduct multi-line load currents. When one or more phases of the multi-line load current exceed a certain limit value, the sensitive elements of the corresponding phases undergo thermal deformation; the terminal block components are uniformly distributed on the upper portion of the fixed base component and are used to conduct multi-line load currents;

[0068] Preferably, the sensitive element includes a busbar, a bent plate, a heat insulating sheet, a conductive sheet, a bimetallic component, a static contact component and a fixing part. One end of the busbar contains a threaded hole for installing an external wire, and one end thereof cooperates with the long end of the bent plate. The first fixed matching end of the bimetallic component, the conductive sheet and the bent plate are abutted together at a bent position to form a first whole. The base portion of the first whole is installed at the fixed end of the busbar. The threaded end of the busbar contains a threaded hole for installing an external wire. The second fixed matching end of the bimetallic component, the conductive sheet and the bent plate are abutted together at a bent position to form a second whole. The base portion of the second whole is installed at the fixed end of the static contact component. The heat insulating sheet is sandwiched between the non-base position of the conductive sheet and the non-base position of the bent plate to isolate the heat between the bent plate and the bimetallic component. The bimetallic component is used to conduct load current.

[0069] Further preferably, when the load current exceeds a certain limit value, the bimetallic component undergoes thermal deformation, and the two ends of its bottom are respectively connected to bent plates, the static contact component is used to contact and conduct electricity with the conductive component, and the fixing member fixes the bus bar, the bent plate, the conductive sheet, and the bimetallic component together. The fixing member is also used to fix the parts in the sensitive element to ensure the relative position of each part;

[0070] Further preferably, the sensitive element in the power control component can select a laminated bimetal with different sensitivities according to different load circuit requirements to achieve conduction and protection of different currents between multiple phases;

[0071] The above-mentioned conductive components include a conductive seat, a moving contact component, a hanging buckle support plate, a monitoring drive plate and a fastener. The conductive seat is used to install the moving contact component, the hanging buckle support plate, the monitoring drive plate and the fastener, and is driven by the motion control component to realize reciprocating motion. The conductive seat is also used to provide insulation between the moving contact components of different phases. The moving contact component is responsible for conducting contact with the static contact component and the terminal board component in the sensitive element, and load conduction and disconnection of the load line current. The moving contact component is installed on one side of the bottom of the conductive seat. The hanging buckle support plate is responsible for cooperating with the support component to provide a quick connection effect between the conductive component and the power control component, and realize the relative fixed position of the conductive component in the support component. The hanging buckle support plate is installed at the upper end of the conductive seat and on the side opposite to the moving contact component;

[0072] Further preferably, the monitoring drive board is responsible for cooperating with the position detection component to drive or conduct the monitoring device in the position detection component, thereby realizing position monitoring of the control device, and the monitoring drive board is installed on the other side of the upper end of the conduction seat;

[0073] Preferably, the movable contact component includes a movable terminal piece 421, a movable contact 422, a moving shaft 423, a second spring 424, and a limiting ring 425. The movable terminal piece is used to transmit the conduction current of the movable contacts at both ends and fix the position of the movable contact. It can move up and down along the moving shaft. The movable terminal piece is installed at the bottom of the movable contact component. The moving shaft installs the entire movable contact component at a specific position on the conductive seat. The second spring is used to provide contact pressure between the movable contact component and the static contact component and the terminal board component. The middle of the second spring passes through the moving shaft, and one end cooperates with the movable terminal piece and the conductive seat. The limiting ring is used to limit the position of the movable shaft on the conductive seat.

[0074] The above-mentioned drive compensation component includes a mounting seat 61, a compensation bimetal 62, a shape-correcting spring piece 63, a buckle plate 64, an adjusting screw 65, a rivet 66 and a spring piece 67. The mounting seat is used to install the compensation bimetal, the shape-correcting spring piece, the buckle plate, and the spring piece, and to transmit the force between the parts. The compensation bimetal is used to perform temperature compensation on the product. When the temperature of the product changes, the shape of the compensation bimetal changes. It is used to change the matching relationship between the drive compensation component and the bimetal component in the sensitive element. It is installed on one side of both ends of the mounting seat. The shape-correcting spring piece is used to adjust the position of the compensation bimetal to avoid excessive deformation of the compensation bimetal. The spring piece is used to control excessive deformation of the buckle plate and control the position of the entire drive compensation component to ensure the matching relationship between the drive compensation component and the power control component and the motion control component. The spring piece is installed between the matching end of the buckle plate and the bimetal component and the mounting seat. The adjusting screws are respectively installed on the ends of the compensation bimetal and the buckle plate to adjust the matching clearance between the compensation bimetal, the buckle plate and the sensitive element.

[0075] Preferably, the buckle plate is in an inverted "U"-shaped structure, with the upper middle portion mounted on the mounting seat, the locking end cooperating with the motion control component, and the temperature control end cooperating with the middle phase bimetallic component. The temperature control end is used to perform temperature compensation on the product. When the product temperature changes, the shape of the temperature control end changes, thereby changing the cooperating relationship between the drive compensation component and the middle phase bimetallic component of the sensitive element.

[0076] Further preferably, the compensation bimetal and buckle plate in the drive compensation component have temperature compensation function. When the environment in which the product is used changes, the two parts cooperate with the power control component in the product to adjust the deformation of the bimetal component in the power control component due to temperature changes, thereby improving the overall reliability and stability of the product under different temperature conditions.

[0077] When the ambient temperature of the product increases, the sensitive element bends and deforms due to the temperature rise, exerting a rotational force on the drive compensation component. At the same time, the compensation bimetal and the buckle plate also deform in the opposite direction, exerting a reverse force on the power control component. The reverse force offsets or partially offsets the rotational force, thereby reducing the amount of decoupling between the motion control mechanism and the lock end caused by the rotational force, keeping the buckle amount within a certain range.

[0078] When the ambient temperature of the product decreases, the sensitive element will bend and deform in the reverse direction due to the temperature drop, and the rotational force applied to the drive compensation component will decrease. Similarly, the reverse force applied to the power control component by the compensation bimetal and the buckle plate will also decrease, and the contact force between the power control component and the drive compensation component will decrease. The shaping spring and the spring will give the compensation bimetal and the buckle plate a reverse force under the action of their own restoring force, thereby reducing the decoupling amount of the motion control mechanism generated by the rotational force from the lock end, so that the buckle amount is kept within a certain range.

[0079] In the present 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 to the base, one end of the probe extends from the base and is connected to the standard part, and the other end extends from the base to cooperate with the monitoring drive board. When the monitoring drive board contacts the two probes, the position detection component is turned on, and when the monitoring drive board separates from the two probes, the position detection component is disconnected.

[0080] In the present invention, the position detection component structure is not limited to the spring probe structure or the micro switch structure. Those skilled in the art may make various changes and improvements to various features and feature combinations not explicitly shown here.

[0081] The above-mentioned supporting components include an upper shell, a positioning piece, an insulating piece, a retaining mechanism, and fasteners. The upper shell is responsible for installing the internal matching parts of the product and is located in the middle of the entire product. The positioning piece is responsible for defining the installation position of the entire product and is installed on the upper end surface of the upper shell. The insulating piece acts as an insulator between the positioning piece and the entire product and is installed between the positioning piece and the upper shell. The retaining mechanism is used to control the product connection process, ensure rapid connection of the product, and prevent arcing between contacts during slow connection. It is installed on one side of the interior of the upper shell.

[0082] Preferably, the positioning piece includes a mounting hole and a positioning pin. The mounting hole is located in the middle of the positioning piece 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 defining the position and direction of the product during use and is located at the end of the positioning piece.

[0083] Preferably, the holding mechanism includes a return spring, a pin, and a force-applying component, the return spring provides a rotational torque to the force-applying component, and the pin passes through the return spring and the force-applying component to fix the two to one side of the upper end of the interior of the upper shell;

[0084] Further preferably, the force-applying component includes a washer, a connecting rod, a pull rod and a spring. The spring is sleeved between the connecting rod and the pull rod. The spring provides the force for restoring and fixing the position of the connecting rod and the pull rod. The washers are installed at both ends of the spring and are responsible for constraining the position and pressure of the spring. The connecting rod is located on both sides of the pull rod, one end of which cooperates with the pin shaft and the other end cooperates with the hook support plate of the conductive component. The pull rod is located in the middle of the force-applying component, one end of which cooperates with the pin shaft and the other end cooperates with the hook support plate of the conductive component.

[0085] When the entire product is in the disconnected state, the pull rod is engaged with the hook of the hook support plate, and the connecting rod is disengaged from the hook support plate;

[0086] When the entire product is in the connected state, the connecting rod is engaged with the hook of the hook support plate, and the pull rod is disengaged from the hook support plate.

[0087] The status monitoring device in the present invention has the functions of multi-phase line parallel switch, power control, position detection and position indication. It reduces the design and use of redundant structures, has high reliability of the whole machine, and has the characteristics of small size and light weight. Through optimized design, the device has the functions of vibration resistance, noise resistance, moisture resistance, heat resistance, salt spray resistance, grease resistance and acidic atmosphere resistance, which can meet the application of products in various complex environments.

[0088] FIG1 shows a partial cross-sectional view of the overall structure of a state monitoring device in a connected state. According to one embodiment of the present invention, the state monitoring device comprises: 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, the power control component 2, the position detection component 3, the conduction component 4, and the drive compensation component 6 are connected to the support component 5 to form the device. The motion control component 1 is used to control the connection and disconnection of the conduction component 4 and the power control component 2, thereby providing an indication of the device state. The power control component 2 is used to achieve line conduction and power control. The position detection component 3 is used to detect the position of the main contact on the conduction component 4 to detect the device state.

[0089] The conducting component 4 is used to realize the conduction and disconnection of the load circuit current; the driving compensation component 6 is used to control the hook position of the motion control component 1 through the synchronization of thermal deformation of the power control component 2;

[0090] 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 conductive component 4 and cooperates with the conductive component 4 to perform reciprocating motion; the upper end of the power control component 2 penetrates into one side of the inner cavity of the support component 5 and cooperates with the drive compensation component 6, and its lower end is exposed below the support component 5 for connection to the external load circuit; 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 conductive component 4 as the conductive component 4 reciprocates; the conductive component 4 is installed in the inner cavity of the support component 5, and its upper end cooperates with the motion control component 1, and its lower end reciprocates with the motion control component 1 and cooperates with the power control component 2; the drive compensation component 6 is installed on one side of the inner cavity of the support component 5, and its upper end cooperates with the support component 5. The drive compensation component 6 can rotate around the support component 5, and its lower end contacts and cooperates with the power control component 2, giving each other a reverse force.

[0091] The specific working process is shown in Figures 4, 7, and 8. It can be summarized as follows: When the pull button 11 in the motion control component 1 is operated to move downward along the axis of the motion control component 1, the pull button 11 drives the motion control mechanism 15 downward, causing the control conduction component 4 to gradually approach the power control component 2. At this time, the conduction component 4 cooperates with the retaining mechanism 54 in the support component 5. The spring 5434 in the retaining mechanism 54 prevents the control conduction component 4 from contacting the power control component 2. When the pressure in the pull button 11 reaches a certain force value, the spring 5434 in the retaining mechanism 54 fails to prevent the control conduction component 4 from contacting the power control component 2. As shown in Figures 1, 2, and 5, the control conduction component 4 and the power control component 2 are instantly connected, placing the product in the on state. At this time, the movable contact 422 in the movable contact component 42 contacts the static contact component 226 and the terminal block component 23 of the respective mating phase, as shown in Figure 5, so that the current in each phase is in the same state. Due to the interaction between the motion control component 1 and the support component 5, the second springs 424 of each phase in the conductive component 4 are compressed, thereby maintaining the contact pressure between the moving and static contacts of the device. As shown in 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 components of the entire motion control mechanism 15 are locked. At the same time, the relative position of the motion control component is maintained by the relative interaction between the compensation bimetal 62 and the upper housing 51, as shown in Figure 15.

[0092] When the entire device is subjected to a high-frequency environment such as vibration and noise, the interaction between the shaping spring 63, the spring 5434, the return spring 541 and the first spring 16 in the motion control component 1 allows the relative matching position of the motion control mechanism 15 and the locking end 641 to remain within a certain range, and can ensure that the motion control mechanism 15 is in contact with the bottom of the locking end 641, thereby ensuring the connection state of the entire product.

[0093] As shown in FIG5 , during the product connection process, the heat-resistant sheet 2253 in the sensitive element 22 contacts the adjusting screw 65 , ensuring that the sensitive element 22 and the driving compensation component 6 are in a relatively static state.

[0094] Under the first coordination logic, the position detection component 3 is separated from the monitoring drive board 44 in the conductive component (4), as shown in FIG5. And the indicator ring 12 is completely embedded in the positioning sleeve 13. Among them, FIG4, FIG5, FIG17, FIG18, FIG22 and FIG23 are state diagrams under the first coordination logic. It is understandable that in some other embodiments, that is, under the second coordination logic, when the control conductive 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 conductive component 4, as shown in FIG25. At this time, the indicator ring 12 is completely embedded in the positioning sleeve 13.

[0095] The temperature compensation process of the condition monitoring device of the present invention when it is turned on can be summarized as follows: when the temperature of the environment around the product changes, it is specifically manifested as a temperature decrease or temperature increase.

[0096] Specifically, when the ambient temperature around the product increases, the sensitive element 22 bends and deforms due to the temperature change, which in turn drives the heat-blocking plate 2253 to move toward the adjustment screw 65, driving the adjustment screw 65 to change its position. The adjustment screw 65 then drives the entire drive compensation component 6 to rotate around the upper shell 51. This movement causes the relative mating position of the motion control mechanism 15 and the locking end 641 to change, reducing the amount of engagement between the motion control mechanism 15 and the locking end 641. In the present invention, when the sensitive element 22 bends and deforms due to changes in ambient temperature, the compensating bimetal 62 and the locking plate 64 also deform, driving the adjustment screw 65 toward the heat-blocking plate 2253, suppressing the reduction in the engagement between the motion control mechanism 15 and the locking end 641 caused by the deformation of the sensitive element 22, and maintaining the engagement within a certain range. This can reduce the reduction in engagement due to temperature changes.

[0097] The force value change in this process can be expressed as follows: when the ambient temperature of the product increases, the sensitive element 22 bends and deforms due to the temperature increase, giving the drive compensation component 6 a rotational force; at the same time, the compensation bimetal 62 and the buckle plate 64 also deform in the opposite direction, giving the power control component 2 a reverse force; the reverse force offsets or partially offsets the rotational force, thereby reducing the amount of decoupling between the motion control mechanism 15 and the locking end 641 generated by the rotational force.

[0098] Specifically, when the ambient temperature around the product decreases, the sensitive element 22 bends and deforms due to the temperature change, driving the heat barrier 2253 away from the adjustment screw 65. At this time, the spring 67 drives the adjustment screw 65 to fit with the heat barrier 2253. The shape adjustment spring 63 and the spring 67 then drive the entire drive compensation component 6 to rotate around the upper shell 51. This movement causes the relative mating position of the motion control mechanism 15 and the lock end 641 to change. In the present invention, when the ambient temperature decreases, the compensation bimetal 62 and the hook plate 64 also deform, driving the adjustment screw 65 away from the heat barrier 2253. The generated force can partially eliminate the increase in the product hooking amount caused by the deformation of the spring 67, so that the hooking amount remains within a certain range. This can reduce the impact of temperature drop on the hooking amount. The fixing clamp 2252 is used to fix the laminated bimetal 2251 and the heat barrier 2253 together.

[0099] The force value change in this process can be expressed as follows: when the ambient temperature of the product decreases, the sensitive element 22 bends and deforms in the reverse direction due to the temperature drop, and the rotational force applied to the drive compensation component 6 decreases. Similarly, the reverse force applied to the power control component 2 by the compensation bimetal 62 and the buckle plate 64 also decreases, and the contact force between the power control component 2 and the drive compensation component 6 decreases. The shape adjustment spring 63 and the spring 67 will give the compensation bimetal (62) and the buckle plate 64 a reverse force compensation force under the action of their own restoring force.

[0100] The overcurrent protection disconnection process of the state monitoring device of the present invention in the on state can be summarized as follows:

[0101] When the current flowing through any one or more of the product's components exceeds a specified value for a certain period of time, the current causes the temperature of each interphase sensitive element 22 to change, leading to bending and deformation. This causes the heat barrier 2253 to move toward the adjustment screw 65, causing the adjustment screw 65 to change position. The adjustment screw 65 then causes the entire drive compensation component 6 to rotate about the upper housing 51. Due to the time difference in temperature transfer, the compensation bimetal 62 and the latch plate 64 undergo minimal or no deformation, failing to drive the adjustment screw 65 toward the heat barrier 2253. This prevents the motion control mechanism 15 from interlocking with the latch end 641, which would otherwise be caused by deformation of the sensitive element 22. This causes the relative position of the motion control mechanism 15 and the latch end 641 to change, gradually reducing the amount of interlock between the motion control mechanism 15 and the latch end 641 until it disengages. This is shown in Figures 4, 7, 8, and 18.

[0102] When the hooking state of the motion control mechanism 15 and the locking end 641 is destroyed, the control conduction component 4 is separated from the power control component 2, so that the product changes from the on state to the off state. At this time, the moving contact 422 in the moving contact component 42 is synchronously separated from the static contact component 226 and the terminal board component 23 between their respective matching phases, so that the multi-phase circuit is changed from the on state to the off state, as shown in Figures 8 and 18.

[0103] At the same time, the position detection component 3 contacts the monitoring drive plate 44 in the conductive component 4, and the position detection component 3 can detect the disconnection state of the conductive component 4. As shown in Figures 4 and 18.

[0104] At this time, the indicator ring 12 is axially disengaged from the positioning sleeve 13, as shown in FIG8 , because the indicator product is in a disconnected state.

[0105] In some embodiments, the disconnection process of the condition monitoring device of the present invention can also be manual disconnection, specifically in the following manner:

[0106] 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, and the relative position of the motion control mechanism 15 and the locking end 641 changes, reducing the amount of engagement between the motion control mechanism 15 and the locking end 641. As the engagement between the motion control mechanism 15 and the locking end 641 gradually decreases, they are finally disengaged, as shown in FIG7 .

[0107] When the hooking state of the motion control mechanism 15 and the locking end 641 is destroyed, the control conduction component 4 is separated from the power control component 2, so that the product changes from the on state to the off state. At this time, the moving contact 422 in the moving contact component 42 is synchronously separated from the static contact component 226 and the terminal board component 23 between their respective matching phases, so that the multi-phase circuit is changed from the on state to the off state, as shown in Figures 8 and 18.

[0108] At the same time, the position detection component 3 contacts the monitoring drive plate 44 in the conductive component 4, and the indicator ring 12 is axially disengaged from the positioning sleeve 13, indicating that the product is in a disconnected state.

A method for using the state monitoring device according to any one of claims 1-18, characterized in that, The method includes: Press the motion control component (1), the conduction component (4) is conducted with the power control component (2). At the same time, the motion control component (1) is buckled with the drive compensation component (6), the conduction component (4) is separated from the position detection component (3), and the external load circuit is conducted. When the external current exceeds a certain threshold, the power control component (2) pushes the drive compensation component (6) to unhook from the motion control component (1).

At the same time, the compensation bimetal (62) and the hanging buckle plate (64) also undergo reverse deformation, giving a reverse force to the power control component (2).

When the temperature of the product's surrounding environment decreases, the sensitive element (22) bends and deforms in the reverse direction due to the decrease in temperature, and the rotational force applied to the drive compensation component (6) decreases.
