Description

Technical Field

[0001] The present 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 play an important role in 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 power systems, 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 existing technology, before testing a circuit breaker, whether it is a newly manufactured circuit breaker or a used circuit breaker, its surface is often clogged with dust or other debris. Testing the circuit breaker in this state can often lead to unexpected problems. Furthermore, during functional testing of the circuit breaker, the circuit is constantly opened and closed, often causing arcs. If the arcs are not promptly addressed, they can affect other components or even cause fires. Therefore, to address the above issues, we provide a circuit breaker production testing device. Summary of the Invention

[0005] The present invention aims to solve the technical problem of how to clean a circuit breaker before testing it. During cleaning, the device automatically disconnects the test circuit to prevent the circuit from being turned on during cleaning due to accidental user contact. Furthermore, the device can automatically replenish insulating gas before testing the circuit breaker, thereby preventing arcing and potential damage to the device during functional testing. A circuit breaker production testing device is provided.

[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 housing, and a controller.

[0007] The housing is disposed on the ground. The continuity detection device is disposed on and connected to the housing. A dust removal device is disposed on the housing, connected to the housing, and is in driving connection with the continuity detection device. A test protection device is disposed on and connected to the housing, and is in driving connection with the continuity detection device. A controller is disposed on the side of the housing and on the ground, and is electrically connected to the continuity detection device and the dust removal device.

[0008] When a user wants to perform a continuity test on a circuit breaker, the user first places the circuit breaker inside the housing, and then activates the continuity detection device and the dust removal device through the controller. When the continuity detection device is activated, the continuity detection device can continuously apply different voltages to the circuit breaker and continuously turn the handle of the circuit breaker to test the working performance of the circuit breaker. After the user completes the circuit breaker test, the user can control the continuity detection device through the controller to drive the dust removal device. The dust removal device can drive the continuity detection action, so that the continuity detection device can disconnect the circuit, and then the surface of the circuit breaker is dusted to avoid the circuit breaker short circuit caused by the cleaning of the dust removal device during the dust removal. 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 to prevent the continuity test device from generating an arc when testing the working performance of the circuit breaker, thereby damaging other devices.

[0009] This function allows the device to clean the circuit breaker before testing it. During cleaning, the device automatically disconnects the test circuit to prevent the circuit from being turned on during cleaning due to accidental user contact. Furthermore, the device automatically replenishes insulating gas before testing the circuit breaker, preventing arcing and potential damage to the device during functional testing.

[0010] Furthermore, the on-off detection device includes: a cylinder, a push block, a bearing base, 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 the 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 sliding groove is transversely arranged inside the shell and on the top surface of the bearing bottom plate. The length of the first sliding groove matches that of the bearing bottom plate.

[0015] The two sliding baffles are respectively arranged vertically inside the shell, between the supporting base and the push block. The two sliding baffles are respectively arranged vertically above the top surface of the supporting base, and are respectively connected to the internal sliding of the first slide groove through the sliding block. 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 fixedly connected to the inner wall end surface of the first slide groove, and the other end is fixedly connected to the side surfaces of the two sliding baffles 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 the other sliding baffle away from the power test line. The shell of the indicator light is fixedly connected to the side of the other sliding baffle away from the power 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 clip.

[0019] To perform a functional test on the circuit breaker, the user first pushes the two sliding baffles apart. This pushes the two first springs apart, causing them to shorten and move the two sliding baffles away from each other along the first slots. The user then places the circuit breaker on the support base and stops pushing the two sliding baffles. This stops pushing the two first springs, which return to their original position. The extended springs push the two sliding baffles together, allowing them to move closer together along the first slots until they clamp and secure the sides of the circuit breaker. The user then connects the power test cable to the circuit breaker's circuit input port and the indicator light cable to the circuit breaker's circuit output port.

[0020] At this point, the user can control the cylinder to extend and energize the cleaning device through the controller. Once current is flowing to the cleaning device, it will power the power test lead, which in turn transmits the current to the circuit breaker's circuit input terminal. The cylinder's telescopic rod extends, driving the push block forward until it contacts a stop. As the push block moves forward, it gradually approaches the circuit breaker handle. When it contacts the handle, it pushes the handle, closing it.

[0021] When the push block moves forward to the front of the circuit breaker handle, 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 circuit breaker handle. When the push block touches the circuit breaker handle, the push block will push the circuit breaker handle 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 through the circuit breaker output end, and the indicator light will light up.

[0022] When the telescopic rod of the cylinder drives the push block to move behind the pushed-open circuit breaker handle, the user can use the controller to control the telescopic rod of the cylinder to continuously extend and retract, and control the current and voltage delivered to the second contact, thereby simulating 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 base plate is set to be 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 base plate and the two sliding baffles are both made of insulating material.

[0026] Setting the supporting base plate and the sliding baffle plate to insulating materials can effectively protect the circuit breaker and prevent current from being transmitted between the supporting base 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 is below the two sliding baffles. Two second sliding grooves are respectively provided on the two opposite side surfaces of the inner wall of the junction box body, and the two second sliding grooves are vertically arranged. The two side surfaces of the supporting base plate are respectively connected by sliders to the inner walls of the two second sliding grooves.

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

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

[0033] The third contact is arranged inside the junction box body, on 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 is passed through the side wall of the junction box body by an electric wire and is fixedly connected to the end of the power test line away from the top surface of the two sliding baffles. There is a distance between the third contact and the second contact, the size of the distance is smaller than that 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. It is located 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 several 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 push 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 push block.

[0037] The pulley is arranged on the outer side of the shell away from the cylinder, and the pulley is fixedly connected to 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 stop block 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 sliding groove is arranged on the outer side of the shell away from the cylinder. The third sliding groove is arranged vertically and is located directly below the pulley.

[0040] The rack is arranged inside the third chute and below the pulley. The rack is slidably connected to the inner wall of the third chute, 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 is sleeved on the side surface of one end of the rotating rod extending to the outer side of the shell away from 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] When the circuit breaker is placed on the supporting base, the supporting base is subjected to the weight of the circuit breaker, which in turn applies a downward force to the two sliders. Under these downward forces, the two sliders move downward along the two second slides. This downward movement of the two sliders extends the two second springs, driving the supporting base downward. This downward movement of the supporting base then drives the two sliding baffles, the two first springs, the circuit breaker, and the vertical guide rod downward. As the vertical guide rod moves downward, it drives the reset spring and the first contact downward until the first contact simultaneously contacts the top surfaces of the second and third contacts. The user then connects the power test cable to the circuit input terminal of the circuit breaker and the indicator light cable to the circuit output terminal of the circuit breaker.

[0044] The telescopic rod of the cylinder is fully extended, driving the push block forward until it contacts the stop block. As the push block moves forward, it gradually approaches the handle of the circuit breaker. When the push block contacts the handle of the circuit breaker, it pushes the handle of the circuit breaker, thereby closing 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 of 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 slot. 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 drives the junction box body to rotate and drives 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 point, the circuit breaker stops applying pressure to the support base, and after the support base stops receiving pressure, it moves along the two second slides away from the bottom surface of the junction box. The movement of the support plate drives the vertical guide rod to move, which in turn drives the return spring and the first contact to move, allowing the first contact to move away from the second and third contacts, thereby disconnecting the second and third contacts. This prevents the brush on the motor shaft from accidentally touching the circuit breaker surface due to accidental touch by nearby users or the user's own misoperation, which could cause the circuit to be connected to the circuit breaker and damage the circuit breaker while cleaning the 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 shell and is covered with an insulating sheath.

[0048] The junction box, vertical guide rod, and rotating rod are constructed of insulating materials to prevent arc travel during circuit breaker testing. Furthermore, an insulating sheath is provided on the side of the cleaning motor's rotating shaft extending into the housing to further protect the cleaning motor and prevent damage.

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

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

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

[0055] As the cam rotates, it continuously squeezes the airbag, injecting the insulating gas inside into the housing. When the cam moves away from the airbag, the airbag returns to its original position, drawing the insulating gas inside the tank back into the airbag. This ensures that by injecting insulating gas into the housing, arcs generated by the continuous on-off switching of the circuit during functional testing of the circuit breaker are quickly extinguished, preventing any impact on the technical performance 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, and the sliding direction is set vertically.

[0061] When the gas content inside the shell reaches a certain level, the air pressure inside the shell will increase. 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 the top of 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 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 are connected to the side of the shell 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 are connected to the side of the shell, thereby causing insulation gas leakage and damaging the respiratory system of surrounding users.

[0065] Furthermore, the device further comprises an air purification device, which 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 the harmful gases that have entered the air purification device.

[0067] Beneficial effects of the present invention:

[0068] 1. The present invention provides a continuity detection device, a dust removal device, a test and protection device, a housing, and a controller that cooperate and support each other. The continuity detection device can perform a functional test on the circuit breaker after the dust removal device has cleaned the circuit breaker. When the dust removal device is cleaning the circuit breaker, the continuity detection device can drive the dust removal device to operate together, thereby cleaning the surface of the circuit breaker before testing, preventing stains or dust adhering to the circuit breaker surface from affecting the circuit breaker's performance. When the circuit breaker is cleaning, the device can forcibly disconnect the test circuit to prevent the circuit from being turned on due to accidental touch by the user, thereby causing damage to the circuit breaker. At the same time, the dust removal device also drives the test and protection device to operate, thereby injecting protective insulating gas into the housing, thereby preventing the continuity detection device from damaging the circuit breaker due to arcing generated by the circuit breaker during the test.

[0073] The following will clearly and completely describe the concept and technical effects of the present invention in conjunction with the embodiments so as to fully understand the purpose, characteristics and effects of the present invention.

[0074] 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.

[0075] Housing 1 is mounted on the ground. A continuity detection device is mounted on and connected to housing 1. A dust removal device is mounted on and connected to housing 1 and is in driving connection with the continuity detection device. A test protection device is mounted on and connected to housing 1 and is in driving connection with the continuity detection device. A controller is mounted on the side of housing 1 and is mounted on the ground. The controller is electrically connected to the continuity detection device and the dust removal device.

[0076] When a user wants to perform an on / off test on a 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. After the on / off detection device is started, the on / off detection device can continuously apply different voltages to the circuit breaker and continuously turn the handle of the circuit breaker to test the working performance of the circuit breaker. After the user completes the circuit breaker test, 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 a short circuit of the circuit breaker due to the cleaning of the dust removal device when the circuit breaker is being dusted. When the dust removal device is in operation, 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 1, thereby preventing the on / off test device from generating an arc when testing the working performance of the circuit breaker, thereby damaging other devices.

[0077] This function allows the device to clean the circuit breaker before testing it. During cleaning, the device automatically disconnects the test circuit to prevent the circuit from being turned on during cleaning due to accidental user contact. Furthermore, the device automatically replenishes insulating gas before testing the circuit breaker, preventing arcing and potential damage to the device during functional testing.

[0078] The on-off detection device includes: a cylinder 201, a push block 202, a bearing base plate 203, two sliding baffles 204, a first sliding groove, two first springs, an indicator light 205, and a power test line.

[0079] The cylinder 201 is arranged on the outer side of the shell 1 and is fixedly connected to the outer side of the shell 1 through a support block. The push rod of the cylinder 201 passes through the side of the shell 1 and extends to the inside of the shell 1. The push rod of the cylinder 201 is slidably connected to the side of the shell 1, and the sliding direction is set horizontally. The cylinder 201 is connected to the air source through a pipeline and is electrically connected to the controller.

[0080] The push block 202 is disposed inside the housing 1 , and is fixedly connected to an end surface of the push rod of the cylinder 201 extending into the interior of the housing 1 .

[0081] The supporting base plate 203 is laterally arranged inside the housing 1 and below the push block 202 . The supporting base plate 203 is connected to the dust removal device.

[0082] The first sliding groove is transversely arranged inside the housing 1 and on the top surface of the supporting base plate 203 . The length of the first sliding groove matches that of the supporting base plate 203 .

[0083] The two sliding baffles 204 are respectively vertically arranged inside the shell 1, between the supporting base plate 203 and the push block 202. The two sliding baffles 204 are respectively vertically arranged above the top surface of the supporting base plate 203, and are respectively connected to the internal sliding of the first slide groove through the sliding block. The two sliding baffles 204 are parallel to each other and there is a gap between them.

[0084] 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 204. One end of the two first springs is fixedly connected to the inner wall end face of the first slide groove, and the other end is fixedly connected to the side faces of the two sliding baffles 204 away from each other.

[0085] The power supply test line is arranged inside the housing 1, and one end is connected to the dust removal device, and the other end extends to the top of one of the sliding baffles 204 and is fixedly connected to the top surface of one of the sliding baffles 204 through a line fixing clip.

[0086] The indicator light 205 is arranged inside the shell 1, on the side of the other sliding baffle 204 away from the power test line. The shell of the indicator light 205 is fixedly connected to the side of the other sliding baffle 204 away from the power test line, and the connecting line of the indicator light 205 is fixedly connected to the top surface of the two sliding baffles 204 through a wire fixing clamp.

[0087] 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. After being pressurized, the two first springs will shorten 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 supporting base 203 and stops applying thrust to the two sliding baffles 204. After the two sliding baffles 204 stop being thrust, they will stop applying thrust to the two first springs. After stopping being thrust, the two first springs 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 side of the circuit breaker. The user then 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.

[0088] At this point, the user can control the cylinder 201 to extend and energize the cleaning device through the controller. Once current is flowing into the cleaning device, it will power the power test line, which will then transmit the current to the circuit access terminal of the circuit breaker. The telescopic rod of the cylinder 201 extends, driving the push block 202 forward until it contacts the stop block 309. As the push block 202 moves forward, it gradually approaches the circuit breaker handle. When the push block 202 contacts the circuit breaker handle, it will push the circuit breaker handle, thereby closing the circuit breaker.

[0089] 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. The push block 202 will gradually approach 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 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.

[0090] When the telescopic rod of the cylinder 201 drives the push block 202 to move behind the pushed circuit breaker handle, the user can use the controller to control the telescopic rod of the cylinder 201 to continuously extend and retract, and control the current and voltage delivered to the second contact 306, thereby simulating the functional use of the circuit breaker in different situations.

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.

[0102] The cleaning motor 308 is arranged on the outer side of the shell 1 and is below the cylinder 201. The cleaning motor 308 is fixedly connected to the outer side of the shell 1 through a support block, and the rotating shaft of the cleaning motor 308 passes through the side wall of the shell 1 and extends to the inside of the shell 1. It is below the junction box body 301. The rotating shaft of the cleaning motor 308 is rotatably connected to the side wall of the shell 1, and the rotating axis is arranged horizontally. The rotating shaft of the cleaning motor 308 extends to the side of the inside of the shell 1 and is provided with a number of brushes.

[0103] The third spring 304 is laterally arranged inside the housing 1 , on the side of the push block 202 away from the cylinder 201 , and one end of the third spring 304 is fixedly connected to the inner wall of the housing 1 .

[0104] 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 .

[0105] 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 of the housing 1 away from the cylinder 201 via a rotating bracket.

[0106] 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 the 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.

[0107] The third sliding groove is arranged on the outer side of the housing 1 away from the cylinder 201 . The third sliding groove is arranged vertically and is directly below the pulley 313 .

[0108] The rack 312 is arranged inside the third chute and below the pulley 313. The rack 312 is slidably connected to the inner wall of the third chute, and the top surface is fixedly connected to the other end of the pull rope 314 passing through the pulley 313.

[0109] The rotating rod 310 is horizontally arranged inside the shell 1, on the side of the junction box body 301 away from the cylinder 201. One end of the rotating rod 310 is fixedly connected to the outer side of the junction box body 301 away from the cylinder 201, and the other end passes through the side wall of the shell 1 and extends to the outer side of the shell 1 away from the cylinder 201, on the side of the third slide groove and below the pulley 313.

[0110] The gear 315 is sleeved on the side surface 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.

[0111] When the circuit breaker is placed on the supporting base 203, the supporting base 203 is subjected to the weight of the circuit breaker, which in turn exerts a downward force on the two sliders. Under the downward force, the two sliders move downward along the two second slide slots. This downward movement of the two sliders extends the two second springs 302, driving the supporting base 203 downward. This downward movement of the supporting base 203 drives the two sliding baffles 204, the two first springs, the circuit breaker, and the vertical guide rod 303 downward. As the vertical guide rod 303 moves downward, it drives the return spring and the first contact 305 downward until the first contact 305 simultaneously contacts the top surfaces of the second contact 306 and the third contact 307. The user then connects the power test cable to the circuit input terminal of the circuit breaker and the connecting cable of the indicator light 205 to the circuit output terminal of the circuit breaker.

[0112] The telescopic rod of the cylinder 201 is fully extended, driving the push block 202 to move forward until it contacts the block 309. As the push block 202 moves forward, it 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 block 309 contacts the push block 202, the block 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 block 309 to move toward the inner wall of the housing 1. When the block 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 engage with the gear 315 and drive the gear 316 to move downward. 15 rotates, and 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 supporting base 203, the two second springs 302, the second contact 306, and the third contact 307 to rotate. The rotation of the supporting base 203 drives the two sliding blocks 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.

[0113] 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.

[0114] At this point, the circuit breaker stops applying pressure to the support base 203. After the pressure ceases, the support base 203 moves along the two second slides away from the bottom surface of the junction box 301. The movement of the support plate drives the vertical guide rod 303, which in turn drives the return spring and the first contact 305, allowing the first contact 305 to separate from the second contact 306 and the third contact 307, thereby disconnecting the second contact 306 from the third contact 307. This prevents the brush on the rotating shaft of the cleaning motor 308 from accidentally touching the circuit breaker surface due to accidental operation by nearby users or the user's own misoperation, which could cause the circuit to be connected to the circuit breaker and damage the circuit breaker while cleaning the surface.

[0115] 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 interior of the housing 1 and is covered with an insulating sheath.

[0116] The junction box 301, vertical guide rod 303, and rotating rod 310 are constructed of insulating materials to prevent arcs from traveling through them during circuit breaker testing. Furthermore, an insulating sheath is provided on the side of the cleaning motor 308 where the rotating shaft extends into the interior of the housing 1, further protecting the cleaning motor 308 and preventing damage.

[0117] 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 .

[0118] 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 .

[0119] The transverse plate 404 is arranged 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 .

[0120] 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.

[0121] The gas injection pipe 405 is arranged above the horizontal plate 404 and is located 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.

[0122] The pressure relief component 403 is disposed above the housing 1 and connected to the top of the housing 1 .

[0123] As cam 401 rotates, it continuously squeezes airbag 402. This squeeze injects the insulating gas inside airbag 402 into housing 1. When cam 401 moves away from airbag 402, airbag 402 returns to its original position, drawing the insulating gas inside the insulating gas tank back into airbag 402. By injecting insulating gas into housing 1, arcs generated by the repeated on-off switching of the circuit during functional testing of the circuit breaker are quickly extinguished, preventing any impact on the technical performance of other devices.

[0124] 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 .

[0125] 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 .

[0126] The pressure relief port 4032 is provided 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 .

[0127] 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 internal closed end of the pressure relief pipe 4031 .

[0128] 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 set vertically.

[0129] 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.

[0130] When the air pressure inside the shell 1 decreases, the sliding disc 4034 stops squeezing in the direction close to the pressure relief spring 4033, and the pressure relief spring 4033 gradually recovers after no longer 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 tube 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.

[0131] 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.

[0132] 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 inside of 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 the surrounding users.

[0133] The air purifier is also included. The air purifier is arranged on the side of the housing 1 and on the ground. The input end of the air purifier is connected to the pressure relief port 4032 through a pipeline.

[0134] 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 that have entered the air purification device.

[0135] Working process:

[0136] 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. After being pressurized, the two first springs will shorten 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 supporting base 203 and stops applying thrust to the two sliding baffles 204. After the two sliding baffles 204 stop being thrust, they will stop applying thrust to the two first springs. After stopping being thrust, the two first springs 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 side of the circuit breaker.

[0137] When the circuit breaker is placed on the supporting base 203, the supporting base 203 is subjected to the weight of the circuit breaker, which in turn exerts a downward force on the two sliders. Under the downward force, the two sliders move downward along the two second slide slots. This downward movement of the two sliders extends the two second springs 302, driving the supporting base 203 downward. This downward movement of the supporting base 203 drives the two sliding baffles 204, the two first springs, the circuit breaker, and the vertical guide rod 303 downward. As the vertical guide rod 303 moves downward, it drives the return spring and the first contact 305 downward until the first contact 305 simultaneously contacts the top surfaces of the second contact 306 and the third contact 307. The user then connects the power test cable to the circuit input terminal of the circuit breaker and the connecting cable of the indicator light 205 to the circuit output terminal of the circuit breaker.

[0138] Before testing a circuit breaker, its surface and electrical terminals should be cleaned to prevent stains or other debris from sticking to the circuit breaker's performance or causing a short circuit. The user can then fully extend cylinder 201 and activate cleaning motor 308 via the controller. The fully extended telescopic rod of cylinder 201 drives pusher block 202 forward until it contacts stopper 309. As pusher block 202 moves forward, it gradually approaches the circuit breaker handle. When it contacts the handle, it pushes the handle, closing 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, it drives the pull rope 314 to move 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 and meshes with the gear 315, driving the gear 313 to move downward. 15 rotates, and 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 supporting base 203, the two second springs 302, the second contact 306, and the third contact 307 to rotate. The rotation of the supporting base 203 drives the two sliding blocks 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.

[0139] 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.

[0140] At this point, the circuit breaker stops applying pressure to the support base 203. After the pressure ceases, the support base 203 moves along the two second slides away from the bottom surface of the junction box 301. The movement of the support plate drives the vertical guide rod 303, which in turn drives the return spring and the first contact 305, allowing the first contact 305 to separate from the second contact 306 and the third contact 307, thereby disconnecting the second contact 306 from the third contact 307. This prevents the brush on the rotating shaft of the cleaning motor 308 from accidentally touching the circuit breaker surface due to accidental operation by nearby users or the user's own misoperation, which could cause the circuit to be connected to the circuit breaker and damage the circuit breaker while cleaning the surface.

[0141] 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 will stop applying pressure to the stopper 309 when it moves backward. After the stopper 309 stops being pressurized, it will stop 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 moves upward, and the rack 312 moves upward, which drives 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 junction box body 301 to rotate, and drives the cam 401 to rotate. The rotation of the junction box body 301 drives the two sliding blocks 309, the circuit breaker, the supporting base 203, the two second springs 302, the second contact 306, and the third contact 307 to rotate. The rotation of the supporting base 203 drives the two sliding blocks 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.

[0142] When cam 401 rotates, it continuously squeezes airbag 402. This squeeze injects the insulating gas inside airbag 402 into housing 1. When cam 401 moves away from airbag 402, airbag 402 returns to its original position, drawing the insulating gas inside the insulating gas tank back into airbag 402. By injecting insulating gas into housing 1, arcs generated by the repeated on-off switching of the circuit during functional testing of the circuit breaker are quickly extinguished, preventing any impact on the technical performance of other devices.

[0143] When the circuit breaker faces the direction of the push block 202 again, the supporting 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 supporting base plate 203 to move downward. The downward movement of the supporting 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. The user then transmits current to the second contact 306 through the controller. 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.

[0144] When the push block 202 moves backward, the push block 202 gradually approaches the handle of the circuit breaker. When the push block 202 contacts the handle of the circuit breaker, the push block 202 pushes 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 terminal of the circuit breaker through the circuit test line will be transmitted to the indicator light 205 through the circuit breaker output terminal, and the indicator light 205 will emit light.

[0145] When the telescopic rod of cylinder 201 drives push block 202 to the rear of the opened circuit breaker handle, the user can use the controller to continuously extend and retract the telescopic rod of cylinder 201 and control the current and voltage supplied to second contact 306, thereby simulating the functional use of the circuit breaker in different situations. After completing the circuit breaker test, the user can use the controller to deactivate power to second contact 306 and cleaning motor 308, restore cylinder 201, collect the tested circuit breaker, and replace it.
