Description

Technical Field

[0001] The invention relates to the field of circuit breaker auxiliary devices, and in particular to a circuit breaker production detection device. Background Art

[0002] Circuit breakers undertake the important task of circuit protection and control in power systems. The stability and reliability of their performance are directly related to the safe operation of power systems.

[0003] With the continuous development of the power system, the performance requirements for circuit breakers are becoming higher and higher. Therefore, circuit breakers need to be strictly tested during the production process.

[0004] In the prior art, before testing a circuit breaker, whether it is a newly manufactured circuit breaker or a used circuit breaker, its surface is often adhered to dust or other things. When testing the circuit breaker in this state, unexpected situations often occur. In addition, when performing functional testing on the circuit breaker, since the circuit is continuously switched on and off through the circuit breaker, the circuit breaker often generates an arc when switching on and off. If the generated arc is not handled in time, it will affect other components or cause a fire. Therefore, in order to solve the above problems, we provide a circuit breaker production detection device. Summary of the invention

[0005] The present invention aims to solve the problem of how to clean the circuit breaker before testing it, and during cleaning, the device can automatically disconnect the test circuit to avoid the circuit being turned on during cleaning due to the user's accidental touch. At the same time, before testing the circuit breaker, the device can also automatically replenish insulating gas to avoid the technical problem of arcing and thus damaging the device during functional testing, and provides a circuit breaker production detection device.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a circuit breaker production detection device, including: an on-off detection device, a dust removal device, a test protection device, a shell, and a controller.

[0007] The housing is arranged on the ground. The on-off detection device is arranged on the housing and connected to the housing. The dust removal device is arranged on the housing, connected to the housing, and drivingly connected to the on-off detection device. The test protection device is arranged on the housing, connected to the housing, and drivingly connected to the on-off detection device. The controller is arranged on the side of the housing and arranged on the ground, and the controller is electrically connected to the on-off detection device and the dust removal device.

[0008] When the user wants to perform an on-off detection on the circuit breaker, the user first places the circuit breaker inside the housing, and then starts the on-off detection device and the dust removal device through the controller. When the on-off detection device is started, the on-off detection device can continuously pass different voltages to the circuit breaker and continuously turn the handle of the circuit breaker to test the working performance of the circuit breaker. When the user completes the circuit breaker detection, the user can control the on-off detection device to drive the dust removal device through the controller. The dust removal device can drive the on-off detection action so that the on-off detection device can disconnect the circuit, and then remove dust from the surface of the circuit breaker to avoid short circuit of the circuit breaker due to the cleaning of the dust removal device when the circuit breaker is dusted. When the dust removal device is activated, the dust removal device can drive the test protection device to operate, and the test protection device can continuously inject protective gas into the housing, thereby avoiding arcing when the on-off test device is testing the working performance of the circuit breaker, thereby damaging other devices.

[0009] This function enables the device to clean the circuit breaker before testing it, and automatically disconnect the test circuit during cleaning to avoid the circuit being turned on during cleaning due to the user's accidental touch. At the same time, the device can also automatically replenish insulating gas before testing the circuit breaker to avoid arcing in the circuit breaker during functional testing, thereby damaging the device.

[0010] Furthermore, the on-off detection device includes: a cylinder, a push block, a bearing base plate, two sliding baffles, a first slide groove, two first springs, an indicator light, and a power test line.

[0011] The cylinder is arranged on the outer side of the shell and is fixedly connected to the outer side of the shell through a support block. The push rod of the cylinder passes through the side of the shell and extends to the inside of the shell. The push rod of the cylinder is slidably connected to the side of the shell, and the sliding direction is set horizontally. The cylinder is connected to the air source through a pipeline and is electrically connected to the controller.

[0012] The push block is arranged inside the shell, and is fixedly connected to an end surface of a push rod of the cylinder extending to the inside of the shell.

[0013] The bearing bottom plate is arranged transversely inside the shell and below the push block, and the bearing bottom plate is connected to the dust removal device.

[0014] The first slide groove is transversely arranged inside the shell and on the top surface of the bearing bottom plate, and the length of the first slide groove matches that of the bearing bottom plate.

[0015] The two sliding baffles are respectively arranged vertically inside the shell, between the bearing bottom plate and the push block, and the two sliding baffles are respectively arranged vertically above the top surface of the bearing bottom plate, and are respectively connected to the inside of the first slide groove through the sliding block, and the two sliding baffles are parallel to each other and there is a distance between them.

[0016] The two first springs are respectively arranged inside the first slide groove and are respectively located on the two outer sides of the two sliding baffles. One end of the two first springs is respectively fixedly connected to the inner wall end surface of the first slide groove, and the other end is respectively fixedly connected to the side surfaces of the two sliding baffles that are away from each other.

[0017] The power supply test line is arranged inside the shell, and one end is connected to the dust removal device, and the other end extends to the top of one of the sliding baffles and is fixedly connected to the top surface of one of the sliding baffles through a line fixing clip.

[0018] The indicator light is arranged inside the shell, on the side of another sliding baffle away from the power supply test line. The shell of the indicator light is fixedly connected to the side of the other sliding baffle away from the power supply test line, and the connecting line of the indicator light is fixedly connected to the top surface of the two sliding baffles through a wire fixing clamp.

[0019] When the user wants to perform a functional test on the circuit breaker, the user can first push the two sliding baffles apart. When the two sliding baffles are pushed apart, the two sliding baffles will apply pressure to the two first springs. The two first springs will shorten after being pressed, and drive the two sliding baffles to move away from each other along the first slide slot. At this time, the user places the circuit breaker on the bearing bottom plate and stops applying thrust to the two sliding baffles. After the two sliding baffles stop being thrusted, they will stop applying thrust to the two first springs. After the two first springs stop being thrusted, they will resume extension. When the two first springs are extended, they will apply thrust to the two sliding baffles, so that the two sliding baffles can move closer to each other along the first slide slot until the two sliding baffles can clamp and fix the side of the circuit breaker. Then the user connects the power test line to the circuit input end of the circuit breaker, and connects the connecting line of the indicator light to the circuit output end of the circuit breaker.

[0020] At this time, the user can control the cylinder to extend through the controller and energize the cleaning device. After the current is passed through the cleaning device, the cleaning device will supply power to the power test line, and the power test line will transmit the current to the circuit access end of the circuit breaker. The telescopic rod of the cylinder extends to drive the push block to move forward until it contacts the block. The push block moves forward and gradually approaches the handle of the circuit breaker. When the push block contacts the handle of the circuit breaker, the push block will push the handle of the circuit breaker to close the circuit breaker.

[0021] When the push block moves forward to the front of the handle of the circuit breaker, the user can control the cylinder to retract through the controller. After the cylinder retracts, it will drive the push block to move backward, and the push block will gradually approach the handle of the circuit breaker. When the push block touches the handle of the circuit breaker, the push block will push the handle of the circuit breaker again to open the circuit breaker. When the circuit breaker is turned on and can work normally, the current transmitted to the circuit access end of the circuit breaker through the circuit test line will be transmitted to the indicator light through the circuit breaker output end, and the indicator light will emit light at this time.

[0022] When the telescopic rod of the cylinder drives the push block to move behind the pushed circuit breaker handle, the user can control the telescopic rod of the cylinder to continuously extend and retract through the controller, and control the current and voltage transmitted to the second contact, so as to simulate the functional use of the circuit breaker in different situations.

[0023] Furthermore, the push block is made of rubber, and the surface of the push block is smooth, and the bottom surface close to the bearing bottom plate is set as an arc surface.

[0024] The push block is made of rubber material to prevent scratches from being caused when the push block applies pressure to the handle of the circuit breaker, or to prevent the handle of the circuit breaker from being broken.

[0025] Furthermore, the bearing bottom plate and the two sliding baffles are made of insulating material.

[0026] Setting the bearing bottom plate and the sliding baffle plate to insulating materials can effectively protect the circuit breaker and prevent the current from being transmitted between the bearing bottom plate and the sliding baffle plate.

[0027] Furthermore, the dust removal device includes: a junction box body, two second springs, a vertical guide rod, a third spring, a first contact, a second contact, a third contact, two second slide grooves, a cleaning motor, a block, a rotating rod, a third slide groove, a rack, a pulley, a pull rope, and a gear.

[0028] The junction box body is arranged inside the shell and below the two sliding baffles. Two second slide grooves are respectively arranged on two opposite sides of the inner wall of the junction box body, and the two second slide grooves are vertically arranged. The two side surfaces of the supporting bottom plate are respectively connected by sliders to the inner walls of the two second slide grooves.

[0029] The two second springs are respectively vertically arranged inside the two second slide grooves and are respectively located above the supporting base plate. The top ends of the two second springs are respectively fixedly connected to the top surfaces of the inner walls of the two second slide grooves, and the bottom ends are respectively fixedly connected to the top surfaces of the sliders connected to the supporting base plate and the two second slide grooves.

[0030] The vertical guide rod is arranged inside the junction box body and below the bearing bottom plate, and the top end of the vertical guide rod is fixedly connected to the bottom surface of the bearing bottom plate.

[0031] The first contact is arranged inside the junction box body and below the vertical guide rod. The first contact is fixedly connected to the bottom end surface of the vertical guide rod through a reset spring.

[0032] The second contact is arranged inside the junction box body and below the first contact. The second contact is fixedly connected to the inner bottom surface of the junction box body and is electrically connected to the controller through an electric wire penetrating the junction box body and the side of the shell.

[0033] The third contact is arranged inside the junction box body, to the side of the second contact and below the first contact. The third contact is fixedly connected to the inner bottom surface of the junction box body, and penetrates the side wall of the junction box body through an electric wire and is fixedly connected to one end of the power supply test line away from the top surfaces of the two sliding baffles. There is a spacing between the third contact and the second contact, the size of the spacing is smaller than the size of the first contact, and they are on the same horizontal line.

[0034] The cleaning motor is arranged on the outer side of the shell and below the cylinder. The cleaning motor is fixedly connected to the outer side of the shell through a support block, and the rotating shaft of the cleaning motor passes through the side wall of the shell and extends to the inside of the shell and is below the junction box body. The rotating shaft of the cleaning motor is rotatably connected to the side wall of the shell, and the rotating axis is arranged horizontally. The rotating shaft of the cleaning motor extends to the side of the inside of the shell and is provided with a plurality of brushes.

[0035] The third spring is transversely arranged inside the shell and is located on the side of the push block away from the cylinder. One end of the third spring is fixedly connected to the inner wall of the shell.

[0036] The stopper is arranged inside the shell and between the pusher block and the third spring. The side surface of the stopper is fixedly connected to the other end of the third spring and is on the same horizontal line as the pusher block.

[0037] The pulley is arranged on the outer side of the shell away from the cylinder, and the pulley is fixedly connected with the outer side of the shell away from the cylinder through a rotating bracket.

[0038] The pull rope is arranged inside the shell and inside the third spring. One end of the pull rope is fixedly connected to a side surface where the stopper is connected to the third spring, and the other end passes through the side wall of the shell and passes through the pulley.

[0039] The third slide groove is arranged on the outer side surface of the shell away from the cylinder, and the third slide groove is arranged vertically and is located directly below the pulley.

[0040] The rack is arranged inside the third slide groove and below the pulley. The rack is slidably connected to the inner wall of the third slide groove, and the top surface is fixedly connected to the other end of the pull rope passing through the pulley.

[0041] The rotating rod is arranged horizontally inside the shell, on the side of the junction box body away from the cylinder, one end of the rotating rod is fixedly connected to the outer side of the junction box body away from the cylinder, and the other end passes through the side wall of the shell and extends to the outer side of the shell away from the cylinder, on the side of the third slide groove and below the pulley.

[0042] The gear sleeve is arranged on the side surface of one end of the rotating rod extending to the outer side of the shell away from the outer side of the cylinder. The gear is fixedly connected to the side surface of the rotating rod and meshes with the tooth surface of the rack.

[0043] At the same time, when the circuit breaker is placed on the bearing base, the bearing base will be subjected to the gravity of the circuit breaker, thereby exerting downward gravity on the two sliders. When the two sliders are subjected to the downward gravity, they will move downward along the two second slides. The downward movement of the two sliders will pull the two second springs to extend and drive the bearing base to move downward. The downward movement of the bearing base will drive the two sliding baffles, the two first springs, the circuit breaker, and the vertical guide rod to move downward together. When the vertical guide rod moves downward, the vertical guide rod will drive the reset spring and the first contact to move downward together until the first contact can contact the top surface of the second contact and the third contact at the same time. Then the user connects the power test line to the circuit input end of the circuit breaker, and connects the connecting line of the indicator light to the circuit output end of the circuit breaker.

[0044] The telescopic rod of the cylinder is fully extended to drive the push block to move forward until it contacts the stopper. The push block moves forward and gradually approaches the handle of the circuit breaker. When the push block contacts the handle of the circuit breaker, the push block pushes the handle of the circuit breaker to close the circuit breaker. When the block contacts the push block, the block will be subjected to the pressure of the push block and will transmit the pressure to the third spring. The third spring will shorten after being subjected to the pressure, thereby driving the block to move toward the inner wall direction close to the shell. When the block moves, it will drive the pull rope to move forward. The movement of the pull rope will drive the pulley to rotate and drive the rack to move downward along the third slide groove. The downward movement of the rack will mesh with the gear and drive the gear to rotate. The rotation of the gear will drive the rotating rod to rotate. The rotation of the rotating rod will drive the junction box body to rotate and drive the cam to rotate. The rotation of the junction box body drives the two sliding blocks, the circuit breaker, the bearing base plate, the two second springs, the second contact, and the third contact to rotate. The rotation of the bearing base plate drives the two sliding baffles, the two first springs, and the circuit breaker to rotate until the top surface of the circuit breaker faces the brush on the rotating shaft of the cleaning motor.

[0045] When the top surface of the circuit breaker faces the brush on the rotating shaft of the cleaning motor, after the cleaning motor is started, the rotating shaft of the cleaning motor rotates, so that the brush thereon can scrub the dust and stains adhered to the surface of the circuit breaker.

[0046] At this time, the circuit breaker will stop applying pressure to the bearing bottom plate, and the bearing bottom plate will move along the two second slide grooves away from the bottom surface of the junction box body after the pressure stops. The movement of the bearing plate drives the vertical guide rod to move, and the movement of the vertical guide rod drives the reset spring and the first contact to move, so that the first contact can leave the second contact and the third contact, thereby disconnecting the second contact and the third contact. This can prevent the brush on the rotating shaft of the cleaning motor from accidentally touching the circuit breaker surface due to the possible accidental touch of nearby users or the user's own misoperation, so that the circuit has been connected to the circuit breaker, and then the circuit breaker is damaged when cleaning its surface.

[0047] Furthermore, the junction box body, the vertical guide rod and the rotating rod are all made of insulating materials, and the rotating shaft of the cleaning motor extends to the side of the inner part of the shell and is covered with an insulating sheath.

[0048] The junction box, vertical guide rod and rotating rod are made of insulating materials to prevent arcs from wandering on the junction box, vertical guide rod and rotating rod when testing the circuit breaker. The side of the rotating shaft of the cleaning motor extending to the inside of the shell is covered with an insulating sheath, which can better protect the cleaning motor itself and avoid damage to the cleaning motor.

[0049] Furthermore, the test protection device includes: a cam, an air bag, a pressure relief component, a cross plate, and an air injection pipe.

[0050] The cam is sleeved on one end of the rotating rod extending to the outer side of the shell away from the cylinder, and is located on the outer side of the gear away from the shell. The cam is fixedly connected to the side of the rotating rod.

[0051] The transverse plate is arranged on the outer side of the shell away from the cylinder, and the side surface of the transverse plate is fixedly connected to the outer side surface of the shell away from the cylinder.

[0052] The air bag is arranged above the horizontal plate and directly below the cam. The air bag is fixedly connected to the top surface of the horizontal plate and is communicated with the insulating gas tank through an air pipe.

[0053] The air injection pipe is arranged above the horizontal plate, between the airbag and the shell, one end of the air injection pipe passes through the interior of the airbag and is communicated with the airbag, and the other end passes through the side of the shell and is communicated with the interior of the shell.

[0054] The pressure relief component is arranged above the shell and connected to the top of the shell.

[0055] When the cam rotates, it will continuously squeeze the airbag, and when the airbag is squeezed, the insulating gas inside the airbag will be injected into the shell. When the cam leaves the airbag, the airbag will recover and draw the insulating gas inside the insulating gas tank into the airbag. In this way, by injecting insulating gas into the shell, it is ensured that when the circuit breaker is tested for functionality, the arc generated by the continuous on and off of the circuit will be quickly extinguished to avoid affecting the technical effects of other devices.

[0056] Furthermore, the pressure relief component includes: a pressure relief pipe, a pressure relief port, a pressure relief spring, and a sliding disc.

[0057] One end of the pressure relief pipe is closed and is vertically arranged above the shell. The open end of the pressure relief pipe passes through the top of the shell and is communicated with the interior of the shell.

[0058] The pressure relief port is arranged on the side of the pressure relief pipe and is located above the shell. The pressure relief port is communicated with the interior of the pressure relief pipe.

[0059] The pressure relief spring is vertically arranged inside the pressure relief pipe, and the top end is fixedly connected to the top surface of the inner closed end of the pressure relief pipe.

[0060] The sliding disc is arranged inside the pressure relief pipe and below the pressure relief spring. The top surface of the sliding disc is fixedly connected to the other end of the pressure relief spring, and the side surface is slidingly connected to the inner wall of the pressure relief pipe. The sliding direction is arranged vertically.

[0061] When the gas content inside the shell reaches a certain level, the air pressure inside the shell will increase, and the increased air pressure will squeeze the sliding disc toward the direction close to the pressure relief spring. The pressure relief spring will gradually shorten under the pressure of the sliding disc. The shortening of the pressure relief spring drives the sliding disc to slide along the inner wall of the pressure relief pipe toward the direction close to the pressure relief spring until the sliding disc can move to above the pressure relief port. At this time, the gas inside the shell will leave the shell through the pressure relief pipe and the pressure relief port, thereby reducing the air pressure inside the shell.

[0062] When the air pressure inside the shell decreases, the sliding disc stops being squeezed toward the direction close to the pressure relief spring. The pressure relief spring will gradually recover after no longer being subjected to the pressure of the sliding disc. The recovery of the pressure relief spring drives the sliding disc to slide along the inner wall of the pressure relief pipe in the direction away from the pressure relief spring until the sliding disc moves to the bottom of the pressure relief port again and recovers.

[0063] Furthermore, the parts where the rotating rod, the cleaning motor, the air injection pipe, the pull rope, the pressure relief pipe and the side of the shell are connected are all connected in a leak-proof manner.

[0064] The parts where the rotating rod, cleaning motor, gas injection pipe, pull rope, pressure relief pipe and the side of the shell are connected are all connected in a leak-proof manner to prevent the insulating gas inside the shell from leaving the shell through the gaps where the rotating rod, cleaning motor, gas injection pipe, pull rope, pressure relief pipe and the side of the shell are connected, thereby causing leakage of insulating gas and damaging the respiratory system of surrounding users.

[0065] Furthermore, it also includes: an air purification device. The air purification device is arranged on the side of the housing and on the ground, and the input end of the air purification device is connected to the pressure relief port through a pipeline.

[0066] After the air inside the housing leaves the housing through the pressure relief port and enters the air purification device, the user can start the air purification device to purify harmful gases that have entered the air purification device.

[0067] Beneficial effects of the present invention: 1. The present invention cooperates and supports each other by setting a continuity detection device, a dust removal device, a test protection device, a housing, and a controller. The continuity detection device can perform a functional test on the circuit breaker after the dust removal device cleans the circuit breaker. When the dust removal device cleans the circuit breaker, the continuity detection device can drive the dust removal device to operate together, so that the surface of the circuit breaker can be cleaned before the circuit breaker is tested, so as to avoid stains or dust adhering to the surface of the circuit breaker affecting the performance of the circuit breaker. When the circuit breaker is cleaned, the device can forcibly disconnect the test circuit to avoid the circuit being turned on due to the user's accidental touch, thereby causing damage to the circuit breaker. At the same time, the dust removal device will also drive the test protection device to operate, so as to inject protective insulating gas into the housing, so as to avoid the continuity detection device from damaging the device due to the arc generated by the circuit breaker during the test when the circuit breaker is functionally tested.

DETAILED DESCRIPTION

[0070] The concept and technical effects of the present invention will be clearly and completely described below in conjunction with embodiments to fully understand the purpose, features and effects of the present invention.

[0071] See also Figure 1-3 : A circuit breaker production detection device, including: an on-off detection device, a dust removal device, a test protection device, a shell 1, and a controller.

[0072] The housing 1 is arranged on the ground. The on-off detection device is arranged on the housing 1 and connected to the housing 1. The dust removal device is arranged on the housing 1, connected to the housing 1, and is drivingly connected to the on-off detection device. The test protection device is arranged on the housing 1, connected to the housing 1, and is drivingly connected to the on-off detection device. The controller is arranged on the side of the housing 1 and on the ground, and the controller is electrically connected to the on-off detection device and the dust removal device.

[0073] When the user wants to perform an on-off detection on the circuit breaker, the user first places the circuit breaker inside the housing 1, and then starts the on-off detection device and the dust removal device through the controller. When the on-off detection device is started, the on-off detection device can continuously pass different voltages to the circuit breaker and continuously turn the handle of the circuit breaker to test the working performance of the circuit breaker. When the user completes the circuit breaker detection, the user can control the on-off detection device to drive the dust removal device through the controller. The dust removal device can drive the on-off detection action so that the on-off detection device can disconnect the circuit, and then remove dust from the surface of the circuit breaker to avoid short circuit of the circuit breaker due to the cleaning of the dust removal device when the circuit breaker is dusted. When the dust removal device is in action, the dust removal device can drive the test protection device to act, and the test protection device can continuously inject protective gas into the housing 1, thereby avoiding arcing when the on-off test device is testing the working performance of the circuit breaker, thereby damaging other devices.

[0084] When the user wants to perform a functional test on the circuit breaker, the user can first push the two sliding baffles 204 apart. When the two sliding baffles 204 are pushed apart, the two sliding baffles 204 will apply pressure to the two first springs. The two first springs will shorten after being subjected to the pressure and drive the two sliding baffles 204 to move away from each other along the first sliding groove. At this time, the user places the circuit breaker on the bearing base plate 203 again and stops applying thrust to the two sliding baffles 204. After the two sliding baffles 204 stop receiving the thrust, they will stop applying thrust to the two first springs. After the two first springs stop receiving the thrust, they will recover and extend. When the two first springs are extended, they will apply thrust to the two sliding baffles 204, so that the two sliding baffles 204 can move closer to each other along the first sliding groove until the two sliding baffles 204 can clamp and fix the sides of the circuit breaker. Then the user connects the power test line to the circuit input terminal of the circuit breaker, and connects the connection line of the indicator light 205 to the circuit output terminal of the circuit breaker.

[0085] At this time, the user can control the cylinder 201 to extend through the controller and energize the cleaning device. After the current is passed through the cleaning device, the cleaning device will supply power to the power test line, and the power test line will transmit the current to the circuit access end of the circuit breaker. The telescopic rod of the cylinder 201 extends to drive the push block 202 to move forward until it contacts the stopper 309. The push block 202 moves forward and gradually approaches the handle of the circuit breaker. When the push block 202 contacts the handle of the circuit breaker, the push block 202 will push the handle of the circuit breaker to close the circuit breaker.

[0086] When the push block 202 moves forward to the front of the handle of the circuit breaker, the user can control the cylinder 201 to retract through the controller. After the cylinder 201 retracts, it will drive the push block 202 to move backward, and the push block 202 will gradually approach the handle of the circuit breaker. When the push block 202 touches the handle of the circuit breaker, the push block 202 will push the handle of the circuit breaker again to open the circuit breaker. When the circuit breaker is turned on and can work normally, the current transmitted to the circuit access end of the circuit breaker through the circuit test line will be transmitted to the indicator light 205 through the circuit breaker output end, and the indicator light 205 will emit light at this time.

[0087] When the telescopic rod of the cylinder 201 drives the push block 202 to move behind the pushed circuit breaker handle, the user can control the telescopic rod of the cylinder 201 to continuously extend and retract through the controller, and control the current and voltage delivered to the second contact 306, so as to simulate the functional use of the circuit breaker in different situations.

[0088] The push block 202 is made of rubber, and the surface of the push block 202 is smooth, and the bottom surface close to the supporting bottom plate 203 is set as an arc surface.

[0089] The push block 202 is made of rubber material to prevent scratches from being caused when the push block 202 applies pressure to the handle of the circuit breaker, or to prevent the handle of the circuit breaker from being broken.

[0090] The supporting base plate 203 and the two sliding baffles 204 are both made of insulating material.

[0091] Setting the supporting base plate 203 and the sliding baffle plate 204 to be insulating materials can effectively protect the circuit breaker and prevent current from being transmitted on the supporting base plate 203 and the sliding baffle plate 204 .

There is a distance between the third contact 307 and the second contact 306, the size of the distance is smaller than the size of the first contact 305, and they are on the same horizontal line.

[0099] The cleaning motor 308 is arranged on the outer side of the outer shell 1 and is below the cylinder 201. The cleaning motor 308 is fixedly connected to the outer side of the outer shell 1 through a support block, and the rotating shaft of the cleaning motor 308 passes through the side wall of the outer shell 1 and extends to the inside of the outer shell 1. It is below the terminal box body 301. The rotating shaft of the cleaning motor 308 is rotatably connected to the side wall of the outer shell 1, and the rotating axis is arranged horizontally. The rotating shaft of the cleaning motor 308 extends to the side of the inner shell 1 and is provided with a plurality of brushes.

[0100] The third spring 304 is transversely arranged inside the housing 1 , and is located on the side of the push block 202 away from the cylinder 201 . One end of the third spring 304 is fixedly connected to the inner wall of the housing 1 .

[0101] The stopper 309 is disposed inside the housing 1 and between the push block 202 and the third spring 304 . The side surface of the stopper 309 is fixedly connected to the other end of the third spring 304 and is on the same horizontal line as the push block 202 .

[0102] The pulley 313 is arranged on the outer side of the housing 1 away from the cylinder 201 , and the pulley 313 is fixedly connected to the outer side surface of the housing 1 away from the cylinder 201 through a rotating bracket.

[0103] The pull rope 314 is arranged inside the housing 1 and inside the third spring 304 . One end of the pull rope 314 is fixedly connected to a side surface where the stopper 309 is connected to the third spring 304 , and the other end passes through the side wall of the housing 1 and passes through the pulley 313 .

[0104] The third slide groove is arranged on the outer side surface of the housing 1 away from the cylinder 201 . The third slide groove is arranged vertically and is located directly below the pulley 313 .

[0105] The rack 312 is arranged inside the third slide groove and below the pulley 313 . The rack 312 is slidably connected to the inner wall of the third slide groove, and the top surface is fixedly connected to the other end of the pull rope 314 passing through the pulley 313 .

[0106] The rotating rod 310 is horizontally arranged inside the outer shell 1, and is located on the side of the terminal box body 301 away from the cylinder 201. One end of the rotating rod 310 is fixedly connected to the outer side of the terminal box body 301 away from the cylinder 201, and the other end passes through the side wall of the outer shell 1 and extends to the outer side of the outer shell 1 away from the cylinder 201, and is located on the side of the third slide groove and below the pulley 313.

[0107] The gear 315 is sleeved on the side surface of one end of the rotating rod 310 extending to the outer side of the housing 1 away from the cylinder 201 . The gear 315 is fixedly connected to the side surface of the rotating rod 310 and meshes with the tooth surface of the rack 312 .

[0108] At the same time, when the circuit breaker is placed on the bearing base plate 203, the bearing base plate 203 will be subjected to the gravity of the circuit breaker, thereby exerting downward gravity on the two sliders. When the two sliders are subjected to the downward gravity, they will move downward along the two second slide grooves. The downward movement of the two sliders will pull the two second springs 302 to extend and drive the bearing base plate 203 to move downward. The downward movement of the bearing base plate 203 will drive the two sliding baffles 204, the two first springs, the circuit breaker, and the vertical guide rod 303 to move downward together. When the vertical guide rod 303 moves downward, the vertical guide rod 303 will drive the reset spring and the first contact 305 to move downward together until the first contact 305 can simultaneously contact the top surfaces of the second contact 306 and the third contact 307. Then the user connects the power test line to the circuit input end of the circuit breaker, and connects the connecting line of the indicator light 205 to the circuit output end of the circuit breaker.

[0109] The telescopic rod of the cylinder 201 is fully extended to drive the push block 202 to move forward until it contacts the stopper 309. The push block 202 moves forward and gradually approaches the handle of the circuit breaker. When the push block 202 contacts the handle of the circuit breaker, the push block 202 will push the handle of the circuit breaker to close the circuit breaker. When the stopper 309 contacts the push block 202, the stopper 309 will be subjected to the pressure of the push block 202 and will transmit the pressure to the third spring 304. The third spring 304 will shorten after being subjected to the pressure, thereby driving the stopper 309 to move toward the inner wall of the housing 1. When the stopper 309 moves, it will drive the pull rope 314 to move forward. The movement of the pull rope 314 will drive the pulley 313 to rotate and drive the rack 312 to move downward along the third slide groove. The rack 312 moves downward to mesh with the gear 315 and drive the gear 316 to move downward. 15 rotates, the rotation of the gear 315 drives the rotating rod 310 to rotate, the rotation of the rotating rod 310 drives the terminal box body 301 to rotate, and drives the cam 401 to rotate, the rotation of the terminal box body 301 drives the two sliding blocks 309, the circuit breaker, the bearing base 203, the two second springs 302, the second contact 306, and the third contact 307 to rotate, the rotation of the bearing base 203 drives the two sliding baffles 204, the two first springs, and the circuit breaker to rotate until the top surface of the circuit breaker faces the brush on the rotating shaft of the cleaning motor 308.

[0110] When the top surface of the circuit breaker faces the brush on the rotating shaft of the cleaning motor 308, after the cleaning motor 308 is started, the rotating shaft of the cleaning motor 308 rotates, so that the brush thereon can scrub the dust and stains adhered to the surface of the circuit breaker.

[0111] At this time, the circuit breaker will stop applying pressure to the bearing bottom plate 203. After the bearing bottom plate 203 stops being subjected to pressure, it will move along the two second slide grooves in the direction away from the bottom surface of the junction box body 301. The movement of the bearing plate drives the vertical guide rod 303 to move. The movement of the vertical guide rod 303 drives the return spring and the first contact 305 to move, so that the first contact 305 can leave the second contact 306 and the third contact 307, thereby disconnecting the second contact 306 and the third contact 307. In this way, the brush on the rotating shaft of the cleaning motor 308 is prevented from being accidentally touched by nearby users or misoperated by the user himself when cleaning the surface of the circuit breaker, so that the circuit has been connected to the circuit breaker, and then the circuit breaker is damaged when cleaning its surface.

[0112] The junction box body 301 , the vertical guide rod 303 , and the rotating rod 310 are all made of insulating materials, and the rotating shaft of the cleaning motor 308 extends to the side of the inside of the housing 1 and is covered with an insulating sheath.

[0113] The junction box body 301, the vertical guide rod 303, and the rotating rod 310 are made of insulating materials to prevent arcs from wandering on the junction box body 301, the vertical guide rod 303, and the rotating rod 310 when the circuit breaker is tested. The side of the rotating shaft of the cleaning motor 308 extending to the inside of the housing 1 is covered with an insulating sheath, which can further protect the cleaning motor 308 itself and avoid damage to the cleaning motor 308.

[0114] The test protection device includes: a cam 401 , an air bag 402 , a pressure relief component 403 , a horizontal plate 404 , and an air injection pipe 405 .

[0115] The cam 401 is sleeved on one end of the rotating rod 310 extending to the outer side of the housing 1 away from the cylinder 201 , and is located on the outer side of the gear 315 away from the housing 1 . The cam 401 is fixedly connected to the side of the rotating rod 310 .

[0116] The transverse plate 404 is disposed on the outer side of the housing 1 away from the cylinder 201 , and the side surface of the transverse plate 404 is fixedly connected to the outer side surface of the housing 1 away from the cylinder 201 .

[0117] The airbag 402 is arranged above the transverse plate 404 and directly below the cam 401 . The airbag 402 is fixedly connected to the top surface of the transverse plate 404 , and the airbag 402 is connected to the insulating gas tank through an air pipe.

[0118] The gas injection pipe 405 is arranged above the horizontal plate 404 and between the airbag 402 and the shell 1. One end of the gas injection pipe 405 passes through the interior of the airbag 402 and is connected to the airbag 402, and the other end passes through the side of the shell 1 and is connected to the interior of the shell 1.

[0119] The pressure relief component 403 is disposed above the housing 1 and connected to the top of the housing 1 .

[0120] When the cam 401 rotates, the rotation of the cam 401 will continuously squeeze the airbag 402, and when the airbag 402 is squeezed, the insulating gas inside the airbag 402 will be injected into the shell 1, and when the cam 401 leaves the airbag 402, the airbag 402 will recover and draw the insulating gas inside the insulating gas tank into the airbag 402. In this way, by injecting insulating gas into the shell 1, it is ensured that when the circuit breaker is tested for functionality, the arc generated by the continuous on and off of the circuit is quickly extinguished to avoid affecting the technical effects of other devices.

[0121] The pressure relief component 403 includes: a pressure relief pipe 4031 , a pressure relief port 4032 , a pressure relief spring 4033 , and a sliding disc 4034 .

[0122] One end of the pressure relief pipe 4031 is closed and is vertically arranged above the shell 1 . The open end of the pressure relief pipe 4031 passes through the top of the shell 1 and is communicated with the interior of the shell 1 .

[0123] The pressure relief port 4032 is disposed on the side of the pressure relief pipe 4031 and is located above the housing 1 . The pressure relief port 4032 is communicated with the interior of the pressure relief pipe 4031 .

[0124] The pressure relief spring 4033 is vertically arranged inside the pressure relief pipe 4031 , and the top end is fixedly connected to the top surface of the inner closed end of the pressure relief pipe 4031 .

[0125] The sliding disc 4034 is arranged inside the pressure relief pipe 4031 and below the pressure relief spring 4033. The top surface of the sliding disc 4034 is fixedly connected to the other end of the pressure relief spring 4033, and the side surface is slidingly connected to the inner wall of the pressure relief pipe 4031, and the sliding direction is vertically arranged.

[0126] When the gas content inside the shell 1 reaches a certain level, the air pressure inside the shell 1 will increase, and the increased air pressure will squeeze the sliding disc 4034 toward the direction close to the pressure relief spring 4033. The pressure relief spring 4033 will gradually shorten after being subjected to the pressure of the sliding disc 4034. The shortening of the pressure relief spring 4033 drives the sliding disc 4034 to slide along the inner wall of the pressure relief pipe 4031 toward the direction close to the pressure relief spring 4033 until the sliding disc 4034 can move to above the pressure relief port 4032. At this time, the gas inside the shell 1 will leave the shell 1 through the pressure relief pipe 4031 and the pressure relief port 4032, thereby reducing the air pressure inside the shell 1.

[0127] When the air pressure inside the shell 1 decreases, the sliding disc 4034 stops being squeezed in the direction close to the pressure relief spring 4033, and the pressure relief spring 4033 gradually recovers after stopping being subjected to the pressure of the sliding disc 4034. The recovery of the pressure relief spring 4033 drives the sliding disc 4034 to slide along the inner wall of the pressure relief pipe 4031 in the direction away from the pressure relief spring 4033 until the sliding disc 4034 moves to the bottom of the pressure relief port 4032 again and recovers.

[0128] The parts where the rotating rod 310, the cleaning motor 308, the air injection pipe 405, the pull rope 314, the pressure relief pipe 4031 are connected to the side of the housing 1 are all connected in a leak-proof manner.

[0129] The parts where the rotating rod 310, the cleaning motor 308, the gas injection pipe 405, the pull rope 314, the pressure relief pipe 4031 are connected to the side of the shell 1 are all connected in a leak-proof manner to prevent the insulating gas inside the shell 1 from leaving the shell 1 through the gaps where the rotating rod 310, the cleaning motor 308, the gas injection pipe 405, the pull rope 314, the pressure relief pipe 4031 are connected to the side of the shell 1, thereby causing leakage of the insulating gas and damaging the respiratory system of surrounding users.

[0130] The air purifier is also included. The air purifier is arranged on the side of the housing 1 and on the ground, and the input end of the air purifier is connected to the pressure relief port 4032 through a pipeline.

[0131] After the air inside the housing 1 leaves the housing 1 through the pressure relief port 4032 and enters the air purification device, the user can start the air purification device to purify the harmful gases entering the air purification device.

[0132] Working process: When the user wants to perform a functional test on the circuit breaker, the user can first push the two sliding baffles 204 apart. When the two sliding baffles 204 are pushed apart, the two sliding baffles 204 will apply pressure to the two first springs. The two first springs will shorten after being subjected to the pressure and drive the two sliding baffles 204 to move away from each other along the first sliding groove. At this time, the user places the circuit breaker on the bearing base plate 203 again and stops applying thrust to the two sliding baffles 204. After the two sliding baffles 204 stop receiving the thrust, they will stop applying thrust to the two first springs. After the two first springs stop receiving the thrust, they will recover and extend. When the two first springs are extended, they will apply thrust to the two sliding baffles 204, so that the two sliding baffles 204 can move closer to each other along the first sliding groove until the two sliding baffles 204 can clamp and fix the sides of the circuit breaker.

[0133] At the same time, when the circuit breaker is placed on the bearing base plate 203, the bearing base plate 203 will be subjected to the gravity of the circuit breaker, thereby exerting downward gravity on the two sliders. When the two sliders are subjected to the downward gravity, they will move downward along the two second slide grooves. The downward movement of the two sliders will pull the two second springs 302 to extend and drive the bearing base plate 203 to move downward. The downward movement of the bearing base plate 203 will drive the two sliding baffles 204, the two first springs, the circuit breaker, and the vertical guide rod 303 to move downward together. When the vertical guide rod 303 moves downward, the vertical guide rod 303 will drive the reset spring and the first contact 305 to move downward together until the first contact 305 can simultaneously contact the top surfaces of the second contact 306 and the third contact 307. Then the user connects the power test line to the circuit input end of the circuit breaker, and connects the connecting line of the indicator light 205 to the circuit output end of the circuit breaker.

[0134] Before testing the circuit breaker, its surface and power terminals should be cleaned to avoid sticky stains or other items that affect the performance of the circuit breaker or cause a short circuit. At this time, the user can control the cylinder 201 to fully extend and the cleaning motor 308 to start through the controller. The telescopic rod of the cylinder 201 is fully extended to drive the push block 202 to move forward until it contacts the stop block 309. The push block 202 moves forward and gradually approaches the handle of the circuit breaker. When the push block 202 contacts the handle of the circuit breaker, the push block 202 will push the handle of the circuit breaker to close the circuit breaker. When the stopper 309 contacts the push block 202, the stopper 309 is subjected to the pressure of the push block 202 and transmits the pressure to the third spring 304. The third spring 304 is shortened after being subjected to the pressure, thereby driving the stopper 309 to move toward the inner wall of the housing 1. When the stopper 309 moves, the pull rope 314 moves forward. The movement of the pull rope 314 drives the pulley 313 to rotate and drives the rack 312 to move downward along the third slide groove. The rack 312 moves downward to mesh with the gear 315 and drives the gear 314 to rotate. 15 rotates, the rotation of the gear 315 drives the rotating rod 310 to rotate, the rotation of the rotating rod 310 drives the terminal box body 301 to rotate, and drives the cam 401 to rotate, the rotation of the terminal box body 301 drives the two sliding blocks 309, the circuit breaker, the bearing base 203, the two second springs 302, the second contact 306, and the third contact 307 to rotate, the rotation of the bearing base 203 drives the two sliding baffles 204, the two first springs, and the circuit breaker to rotate until the top surface of the circuit breaker faces the brush on the rotating shaft of the cleaning motor 308.

[0135] When the top surface of the circuit breaker faces the brush on the rotating shaft of the cleaning motor 308, after the cleaning motor 308 is started, the rotating shaft of the cleaning motor 308 rotates, so that the brush thereon can scrub the dust and stains adhered to the surface of the circuit breaker.

[0136] At this time, the circuit breaker will stop applying pressure to the bearing bottom plate 203. After the bearing bottom plate 203 stops being subjected to pressure, it will move along the two second slide grooves in the direction away from the bottom surface of the junction box body 301. The movement of the bearing plate drives the vertical guide rod 303 to move. The movement of the vertical guide rod 303 drives the return spring and the first contact 305 to move, so that the first contact 305 can leave the second contact 306 and the third contact 307, thereby disconnecting the second contact 306 and the third contact 307. In this way, the brush on the rotating shaft of the cleaning motor 308 is prevented from being accidentally touched by nearby users or misoperated by the user himself when cleaning the surface of the circuit breaker, so that the circuit has been connected to the circuit breaker, and then the circuit breaker is damaged when cleaning its surface.

[0137] When the cleaning of the circuit breaker is completed, the user can control the cylinder 201 to retract through the controller. After the cylinder 201 retracts, it will drive the push block 202 to move backward. The push block 202 moves backward and stops applying pressure to the stopper 309. After the stopper 309 stops being pressurized, it stops applying pressure to the third spring 304. After the third spring 304 stops being pressurized, it will recover, thereby driving the stopper 309 to move away from the inner wall of the housing 1. When the stopper 309 moves, it will drive the pull rope 314 to move backward. The movement of the pull rope 314 will drive the pulley 313 to rotate, and drive the rack 312 along The third slide groove moves upward, and the rack 312 moves upward to drive the gear 315 to rotate. The rotation of the gear 315 drives the rotating rod 310 to rotate. The rotation of the rotating rod 310 drives the terminal box body 301 to rotate, and drives the cam 401 to rotate. The rotation of the terminal box body 301 drives the two sliding blocks 309, the circuit breaker, the bearing base plate 203, the two second springs 302, the second contact 306, and the third contact 307 to rotate. The rotation of the bearing base plate 203 drives the two sliding baffles 204, the two first springs, and the circuit breaker to rotate until the top surface of the circuit breaker faces the direction of the push block 202.

[0138] When the cam 401 rotates, the rotation of the cam 401 will continuously squeeze the airbag 402, and when the airbag 402 is squeezed, the insulating gas inside the airbag 402 will be injected into the housing 1. When the cam 401 leaves the airbag 402, the airbag 402 recovers and draws the insulating gas inside the insulating gas tank into the airbag 402. In this way, by injecting insulating gas into the housing 1, it is ensured that when the circuit breaker is tested for functionality, the arc generated by continuous on and off circuits is quickly extinguished to avoid affecting the technical effects of other devices.

[0139] When the circuit breaker faces the direction of the push block 202 again, the bearing base plate 203 will be subjected to the gravity of the circuit breaker, thereby applying downward gravity to the two sliders. When the two sliders are subjected to the downward gravity, they will move downward along the two second slide grooves. The downward movement of the two sliders will pull the two second springs 302 to extend and drive the bearing base plate 203 to move downward. The downward movement of the bearing base plate 203 will drive the two sliding baffles 204, the two first springs, the circuit breaker, and the vertical guide rod 303 to move downward together. When the vertical guide rod 303 moves downward, the vertical guide rod 303 will drive the reset spring and the first contact 305 to move downward together until the first contact 305 can contact the top surfaces of the second contact 306 and the third contact 307 at the same time. Then the user transmits current to the second contact 306 through the controller, and the current of the second contact 306 is transmitted to the third contact 307 through the first contact 305. The third contact 307 transmits the current to the power test line, and the power test line transmits the current to the circuit breaker access terminal.

[0140] When the push block 202 moves backward, the push block 202 will gradually approach the handle of the circuit breaker. When the push block 202 touches the handle of the circuit breaker, the push block 202 will push the handle of the circuit breaker again to open the circuit breaker. When the circuit breaker is opened and can work normally, the current transmitted to the circuit input end of the circuit breaker through the circuit test line will be transmitted to the indicator light 205 through the circuit breaker output end, and the indicator light 205 will emit light at this time.

[0141] When the telescopic rod of the cylinder 201 drives the push block 202 to move to the rear of the circuit breaker handle that has been pushed open, the user can control the telescopic rod of the cylinder 201 to extend and retract continuously through the controller, and control the current and voltage delivered to the second contact 306, so as to simulate the functional use of the circuit breaker in different situations.
