Description

Technical Field

[0001] The present application relates to the technical field of electricity, and in particular to an energy-saving power distribution cabinet. Background Art

[0002] The power distribution cabinet is the final equipment of the power distribution system. Its main function is to distribute and control power to electrical equipment and provide power-off protection when the circuit is overloaded, short-circuited or leaking. There are many types of power distribution cabinets, including power distribution cabinets, lighting distribution cabinets, metering cabinets, etc. They are widely used in power distribution control of office buildings, residential buildings, schools, hospitals and other living electricity, as well as distribution and power supply of power supply systems in all buildings such as sports buildings and industrial buildings.

[0003] The current power distribution cabinet has a serious defect, that is, when an electrical component fails, it cannot be replaced immediately. The consequences of this problem are extremely serious. Electrical components are key components for monitoring and controlling power parameters. Once a failure occurs, the power distribution cabinet cannot accurately obtain key data, making the entire power distribution cabinet unable to work normally. Summary of the invention

[0004] The purpose of the present application is to provide an energy-saving power distribution cabinet to solve the problem of quickly replacing damaged electrical components.

[0005] An energy-saving distribution cabinet provided in the present application adopts the following technical solution: it includes a box body, a shell fixedly connected to the box body, a plurality of replacement mechanisms installed on the shell, a plurality of electrical components installed on the replacement mechanisms, and a prefabricated circuit installed in the shell, wherein the electrical components are respectively arranged on both sides of the shell, and when one of the electrical components is damaged, the replacement mechanism can automatically replace the corresponding electrical component on the other side to connect with the prefabricated circuit, and disconnect the connecting circuit between the lost electrical component and the prefabricated circuit.

[0006] By adopting the above technical solution, the electrical components are distributed on both sides of the shell and connected to the prefabricated circuit in the shell through the replacement mechanism. The electrical components on one side are connected to the prefabricated circuit and are in working state, while the electrical components on the other side are in standby state. When an electrical component is damaged, the replacement mechanism can automatically detect the fault. Subsequently, the replacement mechanism starts the switching action, connects the corresponding normal electrical components on the other side to the prefabricated circuit through the internal mechanical structure, and cuts off the connection between the damaged electrical components and the prefabricated circuit, thereby ensuring the continuity of the circuit and the normal operation of the energy-saving distribution cabinet.

[0007] In traditional energy-saving distribution cabinets, once an electrical component is damaged, the entire energy-saving distribution cabinet may not work properly, thus affecting the power supply. However, this new energy-saving distribution cabinet can quickly restore the circuit connection with the automatic replacement function of the replacement mechanism, so that the energy-saving distribution cabinet can continue to work normally, effectively reducing the power outage time.

[0008] Preferably, the replacement mechanism includes an energy storage component, a plurality of movable columns slidably connected to the shell, a mounting shell fixedly connected to both ends of the movable columns, and a connecting component respectively connecting the prefabricated circuit and the electrical component. The movable column passes through the shell, and when the mounting shell on one side abuts against the shell, the minimum spacing between the corresponding mounting shell on the other side and the shell is the largest.

[0009] By adopting the above technical solution, the energy storage component provides a power source for the entire replacement mechanism. Under normal conditions, the energy storage component is in an energy storage state, ready to respond to possible electrical component failures at any time; the moving column runs through the shell, and the two ends are connected to the mounting shell. When the energy-saving distribution cabinet is in normal working condition, the mounting shell on one side abuts against the shell. At this time, the electrical components on the mounting shell on this side are connected to the prefabricated circuit and are in working condition, while the minimum spacing between the corresponding mounting shell on the other side and the shell is the largest, and the electrical components on the mounting shell on this side are in standby condition; the connecting components connect the prefabricated circuit and the electrical components respectively. In the process of the moving column driving the mounting shell to move, the connecting component also moves accordingly. When the mounting shell where the standby electrical component is located abuts against the shell, the connecting component quickly connects the standby electrical component to the prefabricated circuit, and at the same time disconnects the connection between the faulty electrical component and the prefabricated circuit, thereby realizing automatic replacement of the electrical components.

[0010] Preferably, the energy storage assembly includes a locking unit, a trigger unit, a force-bearing platform fixedly connected to the moving column, and a first spring sleeved on the moving column, one end of the first spring abuts against the inner wall of the shell, and the other side abuts against the force-bearing platform, the first spring forces the mounting shell on one side to move toward the shell, when the shell on the other side is pressed, the first spring is compressed to store energy, the locking unit locks the force-bearing platform, and when the electrical component on one side is damaged, the trigger unit drives the locking unit to release the restriction on the force-bearing platform.

[0011] By adopting the above technical solution, in the initial state, one end of the first spring abuts against the inner wall of the shell, and the other end abuts against the force-receiving platform. At this time, the first spring is in a natural state or a slightly compressed state, which prompts the mounting shell on one side to move toward the shell, so that the spare electrical component is connected to the prefabricated circuit, and the prefabricated circuit is in a power-off state. When the mounting shell on the other side is manually pressed, the first spring will be compressed and store energy, and at the same time, the electrical component in a normal working state will be connected to the prefabricated circuit. As the first spring is compressed, it stores elastic potential energy. At the same time, the locking unit will lock the force-receiving platform to prevent the first spring from rebounding to maintain the energy storage state. When the trigger unit is activated, it will drive the locking unit to release the restriction on the force-receiving platform. Once the lock is released, the compressed first spring will quickly release the elastic potential energy, pushing the moving column to move in the opposite direction, thereby realizing the switching of the spare electrical components.

[0012] Preferably, the locking unit includes a rotating rod rotatably connected to the inner wall of the shell, a barb fixedly connected to the end of the rotating rod, and a second spring respectively connected to the rotating rod and the inner wall of the shell, the second spring forces the rotating rod to rotate toward the movable column, and the barb can limit the movement of the force platform.

[0013] By adopting the above technical solution, when the installation shell on the other side is manually pressed to store energy, the moving column drives the force-bearing platform to move and compress the first spring. In this process, the force-bearing platform will contact the barb and overcome the elastic force of the second spring to push the barb to rotate, so that the barb will move out of the way and allow the force-bearing platform to continue to move. When the force-bearing platform moves to a certain position, the second spring forces the rotating rod to rotate again, so that the barb returns to the position that limits the movement of the force-bearing platform and completes the locking; the trigger unit acts on the barb, so that it overcomes the elastic force of the second spring and rotates again, so that the barb leaves the force-bearing platform and releases the restriction on the force-bearing platform.

[0014] During the energy storage process, the locking unit can lock the force-bearing platform in the position after compressing the first spring, ensuring that the elastic potential energy stored in the first spring will not be accidentally released. When electrical component switching is required, the locking unit will release the restriction on the force-bearing platform only under the correct action of the trigger unit.

[0015] Preferably, the trigger unit includes a trigger block slidably connected to the movable column, a third spring sleeved on the trigger block, and an actuator fixedly connected to the force-bearing platform, the output section of the actuator is directed toward the trigger block, one end of the third spring is connected to the trigger block, and the other end is connected to the inner wall of the shell, and the third spring forces the trigger block to move toward the force-bearing platform.

[0016] By adopting the above technical solution, the output end of the actuator has a telescopic function. When the spare electrical component needs to be replaced, the output end of the actuator retracts. At this time, the third spring releases the stored elastic potential energy and drives the trigger block to move toward the force-bearing platform. When the trigger block moves to the original position, it will continue to move forward due to inertia, thereby pushing the barb to leave the force-bearing platform, thereby releasing the restriction on the force-bearing platform.

[0017] Preferably, the mounting shell for placing spare electrical components is fixedly connected to a push rod, which passes through the shell and extends to the interior, is fixedly connected to a first rod, the end of the first rod is rotatably connected to a second rod, the push rod is rotatably connected to a third rod, the third rod is provided with a first slide groove and a second slide groove, the rotating rod is fixedly connected to a first column, the first column is slidably connected to the second slide groove, and the second rod is connected to the first slide groove.

[0018] By adopting the above technical solution, when the restriction of the rotating rod is released and the first spring releases energy, the first spring pushes the force-bearing platform to move to the other side. At this time, the first rod, the second rod, and the third rod move together, and the third rod applies an inward force to the rotating shaft, so that the barb can quickly press against the force-bearing platform, and the barb moves along the side surface of the force-bearing platform. In this way, the action of the installation shell for placing spare electrical components hitting the shell is converted into the action of the rotating rod moving on the side surface of the force-bearing platform, so that the impact of the installation shell is buffered.

[0019] Preferably, the actuator is connected in series to the electrical component and the prefabricated circuit.

[0020] By adopting the above technical solution, when the actuator is not powered on, its output end is in a retracted state; and when the actuator is powered on, the output end is extended. Connecting the actuator in series to the electrical component and the prefabricated circuit can play a detection role. When the electrical component is working normally, the actuator is powered on, its output end is extended and drives the third spring to compress, and remains in the extended state. Once the working electrical component is damaged, the actuator will be powered off, at which time the output end of the actuator retracts, thereby releasing the elastic potential energy of the third spring, causing the trigger block to hit the barb.

[0021] Preferably, the connecting assembly includes a conductor connected to the prefabricated circuit, an insulating block fixedly connected to the mounting shell, and a conductive block fixedly connected to the insulating block, a conical first cavity is provided in the insulating block, the conductor passes through the shell and can extend into the first cavity to connect with the conductive block, and the connecting terminal of the electrical component is connected with the conductive block.

[0022] By adopting the above technical solution, when the energy-saving distribution cabinet works normally, the mounting shell on one side abuts against the shell, and the electrical components on the mounting shell on this side are in working state. At this time, the conductor in the connecting assembly passes through the shell, extends into the conical first cavity in the insulating block, and is connected with the conductive block; when the electrical component on one side is damaged, the replacement mechanism starts the switching action. As the moving column moves, the position of the mounting shell changes. The mounting shell that was originally abutted against the shell is separated from the shell, and the mounting shell that was originally in the standby state moves toward the shell. During this process, the insulating block on the standby mounting shell approaches the shell, and the conductor gradually extends into the conical first cavity in the insulating block and is connected with the new conductive block. At the same time, the conductor on the faulty mounting shell is gradually separated from the conductive block, disconnecting the faulty electrical component.

[0023] The tapered first cavity shape can guide the conductor insertion. When the mounting shell moves so that the conductor is close to the insulating block, the larger open end of the tapered cavity can more easily receive the conductor, guide the conductor to move accurately toward the conductive block, and ensure that the conductor can smoothly connect with the conductive block; this greatly shortens the switching time, ensures that the spare electrical components can be quickly put into use, and reduces the power interruption time caused by the connection delay during the switching process.

[0024] Preferably, the prefabricated circuit comprises a plurality of independent sub-circuits, each of which comprises an input end and an output end, and the input end and the output end are respectively connected to the input end and the output end of the electrical component.

[0025] By adopting the above technical solution, the corresponding two sub-circuits are connected through electrical components, thus realizing modular design. When replacing electrical components, only the connection relationship between the electrical components and the sub-circuits needs to be considered, without considering the circuit connectivity relationship between the components.

[0026] Preferably, the connection between the conductor and the shell and the mounting shell is insulated.

[0027] By adopting the above technical solution, during the operation of the energy-saving distribution cabinet, the operator may come into contact with the housing or the installation shell. If the connection between the conductor and the housing or the installation shell is not insulated, when the conductor is energized, it is easy to cause electric shock to the operator. Insulation treatment can effectively avoid the occurrence of such dangerous situations and ensure the personal safety of the operator.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When the electrical components are damaged, the actuator is connected in series between the electrical components and the prefabricated circuit, which can quickly detect the fault and drive the locking unit through the trigger unit to release the restriction on the force-bearing platform. The simple trigger mechanism makes the whole process fast and efficient. The first spring quickly releases the elastic potential energy and pushes the moving column to switch the backup electrical components. The conical first cavity in the connection component can also quickly guide the conductor to connect with the conductive block during the switching process, ensuring that the backup electrical components can be put into use quickly and reduce power outage time;

[0030] 2. The energy storage component is mainly composed of a force-bearing platform, a first spring, a locking unit and a trigger unit. The force-bearing platform is fixed on the moving column, the first spring is sleeved on the moving column to provide power, the rotating rod, the barb and the second spring of the locking unit cooperate to realize the locking and unlocking of the force-bearing platform, and the trigger block, the third spring and the actuator of the trigger unit work together to complete the triggering action. This simple structure makes the coordination between the various components more stable and reliable, reduces the possible failure points caused by the complex structure, and improves the overall reliability of the energy-saving distribution cabinet.

[0031] 3. The box design with double doors at the front and back combined with the simple internal structure provides great convenience for operation and maintenance. Maintenance personnel can easily approach the various components inside the energy-saving distribution cabinet from both the front and back directions, making it more convenient to inspect and repair electrical components in working or standby states. The simple structure prevents maintenance personnel from being confused by complex components during operation, thus improving maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0042] The embodiment of the present application discloses an energy-saving power distribution cabinet.

[0043] Example 1, reference Figure 1 An energy-saving power distribution cabinet includes a box body 1, a shell 2 fixedly connected to the box body 1, a plurality of replacement mechanisms 5 installed on the shell 2, a plurality of electrical components 4 installed on the replacement mechanism 5, and a prefabricated circuit 3 installed in the shell 2. The shell 2 divides the box body 1 into a working area 11 and a spare area 12. The electrical components 4 are respectively arranged in the working area 11 and the spare area 12. When one of the electrical components 4 in the working area 11 is damaged, the replacement mechanism 5 can automatically replace the electrical component 4 corresponding to the spare area 12 to connect with the prefabricated circuit 3, and disconnect the connection circuit between the lost electrical component 4 and the prefabricated circuit 3; the electrical components 4 in Example 1 take the main meter 41, a plurality of sub-meters 43, and a circuit breaker 42 as an example. Electricity is connected from the input terminal of the main meter 41 and distributed to different sub-meters 43 from the output terminal. The circuit breaker 42 is connected between the sub-meter 43 and the main meter 41.

[0044] refer to Figure 2The replacement mechanism 5 includes an energy storage component 51, a plurality of moving columns 52 slidably connected to the housing 2, a mounting shell 53 fixedly connected to both ends of the moving column 52, and a connecting component 54 respectively connecting the prefabricated circuit 3 and the electrical component 4. The moving column 52 passes through the housing 2, and the mounting shell 53 is respectively located in the working area 11 and the spare area 12. The electrical components 4 are respectively installed in the mounting shell 53; in the initial state when no power is supplied, the mounting shell 53 in the spare area 12 abuts against the housing 2, and the mounting shell 53 in the working area 11 is separated from the housing 2. At this time, the spare electrical components 4 is connected with the prefabricated circuit 3 under the action of the connecting component 54. When the installation shell 53 in the working area 11 is manually pressed, the installation shell 53 in the working area 11 abuts against the housing 2, and the electrical component 4 is connected with the prefabricated circuit 3 through the connecting component 54. When the installation shell 53 is manually pressed, on the one hand, the electrical component 4 in the working area 11 is connected with the prefabricated circuit 3, and on the other hand, the energy storage component 51 is charged. When the spare electrical component 4 needs to be replaced, the energy storage component 51 releases energy to drive the corresponding electrical component 4 in the spare area 12 to be replaced.

[0045] refer to Figure 2 and Figure 3 The energy storage assembly 51 includes a locking unit 511, a trigger unit 512, a force receiving platform 513 fixedly connected to the moving column 52, and a first spring 514 sleeved on the moving column 52. One end of the first spring 514 abuts against the inner wall of the shell 2, and the other side abuts against the force receiving platform 513. The first spring 514 forces the mounting shell 53 on one side to move toward the shell 2. In the initial state, one end of the first spring 514 abuts against the inner wall of the shell 2, and the other end abuts against the force receiving platform 513. At this time, the first spring 514 is in a natural state or a slightly compressed state. The mounting shell 53 in the standby area 12 abuts against the shell 2, and the mounting shell 53 in the working area 11 is separated from the shell 2. When the mounting shell 53 in the working area 11 is pressed down, the first spring 514 will be compressed and store energy, and at the same time, the electrical components 4 in the working area 11 are connected to the prefabricated circuit 3. As the first spring 514 is compressed, it stores elastic potential energy. At the same time, the locking component will lock the force-bearing platform 513 to prevent the first spring 514 from rebounding to maintain the energy storage state. Only when the trigger component is activated, it will drive the locking component to release the restriction on the force-bearing platform 513. Once the lock is released, the compressed first spring 514 will quickly release the elastic potential energy and push the moving column 52 to move in the opposite direction, thereby realizing the switching of the standby electrical component 4.

[0046] refer to Figure 2 and Figure 3The locking assembly includes a rotating rod 5111 rotatably connected to the inner wall of the housing 2, a barb 5112 fixedly connected to the end of the rotating rod 5111, and a second spring 5113 respectively connected to the rotating rod 5111 and the inner wall of the housing 2. The second spring 5113 forces the rotating rod 5111 to rotate toward the moving column 52, and the barb 5112 can limit the movement of the force-bearing platform 513. When the mounting shell 53 on the other side is manually pressed to store energy, the moving column 52 drives the force-bearing platform 513 to move and compress the first spring 514. During this process, the force-bearing platform 513 will contact the hook 5112 and overcome the elastic force of the second spring 5113 to push the hook 5112 to rotate, causing the hook 5112 to move out of the way and allowing the force-bearing platform 513 to continue moving. When the force-bearing platform 513 moves to a certain position, the second spring 5113 forces the rotating rod 5111 to rotate again, causing the hook 5112 to return to the position where the movement of the force-bearing platform 513 is restricted, thereby completing the locking. The trigger assembly acts on the hook 5112, causing it to overcome the elastic force of the second spring 5113 and rotate again, allowing the hook 5112 to leave the force-bearing platform 513 and releasing the restriction on the force-bearing platform 513.

[0047] refer to Figure 2 and Figure 3 The trigger assembly includes a trigger block 5122 slidably connected to the moving column 52, a third spring 5123 sleeved on the trigger block 5122, and an actuator 5121 fixedly connected to the force-bearing platform 513. In this embodiment, the actuator 5121 takes an electric telescopic rod as an example. When the actuator 5121 is powered on, the output end of the actuator 5121 will extend. When the power is off, the output end of the actuator 5121 will retract under the action of the internal reset member. The output section of the actuator 5121 is directed toward the trigger block 5122. One end of the third spring 5123 is connected to the trigger block 5122, and the other end is connected to the inner wall of the shell 2. The third spring 5123 forces the trigger block 5122 to move toward the force-bearing platform 513. When the power is on, the actuator 5121 The output end extends out to push the trigger block 5122 to compress the third spring 5123 and maintain the third spring 5123 in a compressed state. When the power is off, the output end of the actuator 5121 retracts, and the trigger block 5122 moves toward the force-bearing platform 513 under the action of the third spring 5123. When the trigger block 5122 moves to the initial state position, due to inertia the trigger block 5122 will continue to move and hit the barb 5112, causing the barb 5112 to move away and release the capacity of the energy storage component 51; the actuator 5121 is connected in series to the electrical component 4 and the prefabricated circuit 3, thus forming a detection method. When the electrical component 4 is damaged, the trigger component will be triggered, and a button component for controlling the actuator 5121 is provided on the shell 2.

[0048] refer to Figure 4 and Figure 5, the mounting shell 53 of the spare area 12 is fixedly connected with a push rod 55, the push rod 55 passes through the shell 2 and extends to the inside, the push rod 55 is fixedly connected with a first rod 551, the end of the first rod 551 is rotatably connected with the second rod 552, the push rod 55 is rotatably connected with the third rod 553, the third rod 553 is provided with a first slide groove 555 and a second slide groove 556, the rotating rod 5111 is fixedly connected with a first column 554, the first column 554 is slidably connected with the second slide groove 556, the second rod 552 and the first slide groove 555, the first rod 551, the second rod 552, the third rod 553, and the push rod 55 form a connecting rod mechanism, when the rotating rod 5111 rotates, the third rod 553 and the second rod 552 will follow the corresponding movement changes, thus ensuring that the movement of the rotating rod 5111 will not be affected by the third The lever 553 is restricted by the second lever 552. When the trigger block 5122 hits the hook 5112 to release the restriction of the force-bearing platform 513, the movable column 52 and the push rod 55 will move at the same time, so that the entire connecting rod moves toward the working area 11 together. In this way, the third lever 553 will apply a force to the rotating rod 5111, so that the hook 5112 can be more closely attached to the side surface of the force-bearing platform 513. When the hook 5112 abuts against the force-bearing platform 513, the movement of the mounting shell 53 in the spare area 12 can be alleviated, thereby avoiding the collision of the mounting shell 53 with the shell 2. The surface of the force-bearing platform 513 is provided with a slope 5131, so that the hook 5112 can approach the movable column 52 at a certain speed along the slope 5131, so that the mounting shell 53 and the shell 2 will not collide violently.

[0049] refer to Figure 6 and Figure 7 When the mounting shell 53 in the working area 11 is manually pressed down, the entire connecting rod mechanism and the moving column 52 will move toward the standby area 12, referring to Figure 7 At this time, the force-bearing platform 513 can push the two sides of the hook 5112 box apart, and the third rod 553 and the second rod 552 will also rotate accordingly, so that the rotating rod 5111 can rotate smoothly. When the hook 5112 passes through the force-bearing platform 513, it will lock the locking column force-bearing platform 513. Figure 6 ; However, the trigger block 5122 hits the hook 5112 to release the force restriction. Under the action of the first spring 514, the movable column 52 moves toward the working area 11 together with the entire connecting rod mechanism. The third rod 553 will apply a force to the rotating rod 5111, so that the hook 5112 can abut against the force-bearing platform 513, so that the movement of the connecting rod mechanism and the movable column 52 is restricted, thereby alleviating the impact of the installation shell 53 on the shell 2. When the hook 5112 does not abut against the force-bearing platform 513, the installation shell 53 can move quickly toward the shell 2, so that the components in the spare area 12 can be quickly connected with the prefabricated circuit 3. Due to the existence of the slope 5131, the installation shell 53 can slowly approach the shell 2 after the components are connected with the prefabricated circuit 3, thereby preventing the occurrence of impact.

[0050] refer to Figure 8 The connection assembly 54 includes a conductor 541 connected to the prefabricated circuit 3, an insulating block 542 fixedly connected to the mounting shell 53, and a conductive block 453 fixedly connected to the insulating block 542. A conical first cavity 545 is provided in the insulating block 542. The conductor 541 passes through the housing 2 and can extend into the first cavity 545 to communicate with the conductive block 453. The connecting terminal of the electrical component 4 is connected to the conductive block 453. During the movement of the mounting frame, the distance between the conductive block 453 and the conductor 541 will change. When the conductive block 453 contacts the conductor 541, the electrical component 4 is connected to the prefabricated circuit 3. In this way, the connection of the electrical component 4 corresponds to the movement of the mounting shell 53. The first cavity 545 is conical and has a guiding function. The larger opening end of the conical cavity can more easily receive the conductor 541, guide the conductor 541 to accurately move toward the conductive block 453, and ensure that the conductor 541 can be smoothly connected to the conductive block 453.

[0051] refer to Figure 2 and Figure 3 The prefabricated circuit 3 is composed of several sections of independent sub-circuits, each of which includes an access end and an output end, the access end and the output end are respectively connected to the input end and the output end of the electrical element 4. In this embodiment, four sections of sub-circuits are taken as an example, namely the first circuit 31, the second circuit 32, the third circuit 33, and the fourth circuit 34. The access end of the first circuit 31 is connected to the power system, and the output end is connected to the conductor 541; the access end and the output end of the second circuit 32 and the third circuit 33 are both connected to the conductor 541; the access end of the fourth circuit 34 is connected to the conductor 541, and the output end is connected to the external working circuit.

[0052] The implementation principle of an energy-saving power distribution cabinet in the embodiment of the present application is as follows: in the initial non-powered state, the housing 2 of the energy-saving power distribution cabinet divides the box body 1 into a working area 11 and a standby area 12. The first spring 514 is in a natural state or a slightly compressed state, forcing the mounting shell 53 of the standby area 12 to abut against the housing 2, and at this time, the standby electrical component 4 is connected to the prefabricated circuit 3 under the action of the connecting assembly 54. The mounting shell 53 of the working area 11 is separated from the housing 2, and the electrical component 4 of the working area 11 is not connected to the prefabricated circuit 3;

[0053] When the installation shell 53 in the working area 11 is manually pressed, the installation shell 53 approaches and abuts against the housing 2. In this process, the moving column 52 drives the force-bearing platform 513 to move, compressing the first spring 514 to store energy. At the same time, the electrical components 4 in the working area 11 are connected to the prefabricated circuit 3 through the connecting assembly 54, so that electricity is connected from the input terminal of the main meter 41, and distributed to different sub-meters 43 through the output terminal. The circuit breaker 42 between the sub-meter 43 and the main meter 41 is in a closed state, and the electrical components 4 in the working area 11 start to work normally; as the first spring 514 is compressed, elastic potential energy is stored. At the same time, the rotating rod 5111 of the locking assembly rotates under the action of the second spring 5113, so that the barb 5112 at the end of the rotating rod 5111 limits the movement of the force-bearing platform 513 and maintains the energy storage state; the actuator 5121 in the trigger assembly is in the energized state, and its output end extends and pushes the trigger block 5122 to compress the third spring 5123, maintaining the compressed state of the third spring 5123. The actuator 5121 is connected in series between the electrical component 4 and the prefabricated circuit 3. When the electrical component 4 works normally, the actuator 5121 remains powered on.

[0054] When an electrical component 4 in the working area 11 is damaged, the actuator 5121 is powered off. The output end of the actuator 5121 retracts under the action of the internal reset member, and the trigger block 5122 moves toward the force-bearing platform 513 under the action of the third spring 5123. When the trigger block 5122 moves to the initial state position, it continues to move due to inertia and hits the barb 5112, so that the barb 5112 overcomes the elastic force of the second spring 5113 and rotates to make way, thereby releasing the restriction on the force-bearing platform 513; once the lock is released, the compressed first spring 514 quickly releases the elastic potential energy, pushing the moving column 52 to move in the opposite direction. The moving column 52 drives the mounting shell 53 to move, so that the mounting shell 53 originally in the working area 11 is separated from the shell 2, and the mounting shell 53 originally in the spare area 12 is in contact with the shell 2.

[0055] During the movement of the installation shell 53, the distance between the conductive block 453 and the conductor 541 in the connection assembly 54 changes. When the installation shell 53 of the spare area 12 approaches the housing 2, the conductor 541 gradually extends into the conical first cavity 545 in the insulating block 542. Under the guidance of the first cavity 545, the conductor 541 accurately moves toward the conductive block 453 and connects. At this time, the spare electrical component 4 is connected to the prefabricated circuit 3, while the faulty electrical component 4 in the working area 11 is disconnected from the prefabricated circuit 3. Each sub-circuit in the prefabricated circuit 3 also adjusts the connection state as the electrical component 4 switches to ensure the normal transmission of power.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
