Technical Field

[0001] The invention relates to the technical field of pole-mounted circuit breaker detection, in particular to a balance adjustment test device for a magnetically controlled pole-mounted circuit breaker integrating primary and secondary equipment. Background Art

[0002] With the rapid development of my country's economy and the continuous increase in power supply, especially the increasing dependence of various types of customers on electricity, in order to improve the power supply reliability of the power grid, pole-mounted circuit breakers are often used on the connection, section and branch lines in the power grid to improve the power supply reliability of the power grid.

[0003] According to Chinese patent CN117766348B, a balance adjustment test device for circuit breakers can be used to adapt to circuit breakers of different sizes by adjusting the horizontal position of the adjustment mechanism. The test mechanism can test the balance of the circuit breaker and cooperate with the adjustment mechanism to adjust the balance, which shortens the operation time, saves construction costs, and ensures construction efficiency.

[0004] At present, the magnetically controlled column-mounted circuit breaker with integrated primary and secondary equipment adopts advanced magnetic control technology and controls the opening and closing operations of the circuit breaker through electromagnetic force. It has the characteristics of fast response speed and high reliability. The primary and secondary equipment are deeply integrated during the design, manufacturing and use process to form an integrated device to improve the intelligence and automation level of the power system. Therefore, it is extremely important to detect the life, opening and closing response speed, balance and other aspects of the circuit breaker to ensure the safe use of the circuit breaker.

[0005] In the design of the existing magnetically controlled column-mounted circuit breaker integrating primary and secondary equipment, the structure of the magnetically controlled column-mounted circuit breaker is relatively complex, which makes it inconvenient to detect and record the parameters of the number of opening and closing times, closing time, opening and closing response speed, and closing current of the circuit breaker. Moreover, after the magnetically controlled column-mounted circuit breaker is installed on the column, it is inconvenient to detect whether the magnetically controlled column-mounted circuit breaker is in a balanced state. Summary of the invention

[0006] The purpose of the present invention is to make up for the shortcomings of the prior art and provide a balance adjustment test device for a magnetically controlled column-mounted circuit breaker that integrates primary and secondary equipment. This solution can not only facilitate the testing of the balance, opening and closing time, opening and closing speed and closing current of the magnetically controlled column-mounted circuit breaker, but also has an extremely simple installation method, and the magnetically controlled column-mounted circuit breaker can also be tested after it is installed on the column.

[0007] To solve the above problems, the present invention provides the following technical solutions: a balance adjustment test device for a magnetically controlled column-mounted circuit breaker with integrated primary and secondary devices, comprising a column-mounted circuit breaker box, a pole body fixedly connected to the upper surface of the column-mounted circuit breaker box, and a pole mechanism located inside the pole body, wherein the pole mechanism comprises a static contact fixed to the top wall of the pole body, and a moving contact directly below the static contact, wherein the lower end of the moving contact is fixedly connected to an insulating push rod.

[0008] A magnetic control mechanism connected to an insulating push rod is arranged inside the pole-mounted circuit breaker box. The magnetic control mechanism includes a contact rod that slides with the inner wall of the pole-mounted circuit breaker box, and a fast transmission assembly connected to the contact rod. The magnetic control mechanism is used to push and pull the moving contact and the static contact for fast opening and closing through the insulating push rod.

[0009] A detection mechanism connected to the contact rod is arranged outside the column-mounted circuit breaker box, and the detection mechanism includes a detection box installed outside the column-mounted circuit breaker box, and a contact sensor installed on the inner wall of the detection box and facing the outer end of the contact rod, and the contact sensor is used to detect the number and speed of opening and closing between the moving contact and the static contact through contact with the contact rod; the detection mechanism also includes a horizontal detection component and a current detection component located inside the detection box.

[0010] Furthermore, the pole mechanism also includes a vacuum interrupter fixed on the inner wall of the pole body and located outside the static contact and the moving contact, the lower end of the moving contact slides through the vacuum interrupter and is fixedly connected to a connecting wire, the outer surface of the pole body is fixedly connected to a current transformer, and the interior of the current transformer is fixedly connected to a conductive rod connected to the outer end of the connecting wire.

[0011] The beneficial effect of adopting the above further solution is that by setting a current transformer, the current transformer includes a magnetic core, a coil and an inductor, the coil is wound around the magnetic core, and the inductor senses the electromotive force and converts it into a corresponding electrical signal output to provide reliable measurement data.

[0012] Furthermore, the pole mechanism also includes an insulating protective tube fixed to the outer surface of the insulating push rod, and a fixing ring fixedly connected to the bottom wall of the pole body, and the upper surface of the fixing ring is fixedly connected to an overtravel spring sleeved on the outer surface of the insulating push rod.

[0013] The beneficial effect of adopting the above further scheme is that by setting an insulating protective tube, the insulating protective tube mainly protects the insulating push rod to prevent the insulating push rod from being damaged by current. The overtravel spring can ensure the contact pressure after the static contact and the moving contact come into contact, thereby ensuring good contact of the switch.

[0014] Furthermore, the magnetic control mechanism also includes a commutator fixed to the bottom wall of the column-mounted circuit breaker box, and a magnetic column fixed to the output end of the commutator, the upper surface of the magnetic column is fixedly connected to a sliding rod, the outer surface of the sliding rod is slidably matched with a magnetic ring fixedly connected to the lower end of the insulating push rod, and the outer surface of the sliding rod is slidably connected to the reserved hole at the lower end of the insulating push rod.

[0015] The beneficial effect of adopting the above further scheme is that by setting a commutator, the commutator passing a positive pulse current can change the magnetic field transformation of the magnetic column, so that the magnetic column can attract or repel the magnetic ring, making it easier to push the insulating push rod to contact or separate the moving contact and the static contact, thereby realizing the operation of opening and closing the switch.

[0016] Furthermore, the rapid transmission assembly includes two transmission plates hinged to the protrusions on the outer surface of the magnetic ring, and a fixed rod fixed to the inner wall of the column-mounted circuit breaker box, a slidable ring is provided on the outer surface of the fixed rod and is hinged to the outer end of the transmission plate, a first telescopic spring is sleeved on the outer surface of the fixed rod, and a second telescopic spring is installed between the two transmission plates through the protruding rod.

[0017] The beneficial effect of adopting the above further scheme is that by setting up a rapid transmission component, it is possible to facilitate the attraction or repulsion between the magnetic column and the magnetic ring so that the magnetic ring drives the transmission plate to slide under the limiting action of the fixed rod, and the response speed when closing the switch can be improved through the action of the first telescopic spring and the second telescopic spring.

[0018] Furthermore, the magnetic control mechanism also includes two hinged plates hinged to the protrusions on the outer surface of the magnetic ring, and the outer ends of the hinged plates are hinged to the contact rod. The hinged plates are used for the magnetic control mechanism to drive the contact rod to extend and retract at the pole-mounted circuit breaker box when controlling the pole mechanism to open and close.

[0019] The beneficial effect of adopting the above further solution is that, by providing a hinged plate, when the magnetic ring moves up and down to open and close the switch, the hinged plate can drive the contact rod to slide under the limiting action of the column-mounted circuit breaker box.

[0020] Furthermore, an outgoing terminal is installed at the outer end of the conductive rod, and an incoming terminal is installed at the upper end of the static contact.

[0021] The beneficial effect of adopting the above further solution is that by providing the outgoing terminal and the incoming terminal, the connection and transmission of the line can be facilitated.

[0022] Furthermore, the detection mechanism also includes a limiting cylinder fixed to the inner wall of the detection box and slidably matched with the contact rod, and the limiting cylinder is used to ensure that the contact rod is in precise contact with the contact sensor when sliding and retracting.

[0023] The beneficial effect of adopting the above further scheme is that by providing a limit cylinder, the contact rod can be easily limited in sliding, so that the contact rod can accurately contact the contact end of the contact sensor when it telescopes and slides at the column-mounted circuit breaker box, thereby enabling the contact sensor to record the closing or opening of the moving contact and the static contact.

[0024] Furthermore, the level detection assembly includes a support plate fixed to the inner wall of the detection box, and a level detector installed on the upper surface of the support plate, and the level detector is used to detect the horizontal state of the pole-mounted circuit breaker on the pole.

[0025] The beneficial effect of adopting the above further solution is that, by providing a level detection component, it is possible to facilitate level detection of the entire device, thereby facilitating improvement of practicality and safety.

[0026] Furthermore, the current detection component includes a current detector installed on the inner wall of the detection box, and the connection end of the current detector passes through the detection box and extends to the upper part of the detection box. The detection mechanism also includes a controller installed on the inner wall of the detection box, and a display installed on the outer surface of the detection box. The controller is used to calculate, collect, transmit and record the detection data.

[0027] The beneficial effect of adopting the above further scheme is that by setting a current detection component, when the circuit breaker performs a closing current detection, the outlet terminal and the current detector connection end are first connected through the line. At this time, by opening and closing the circuit, the current can be transmitted to the current detector for testing and recording, and the controller is used for control and information transmission, and the current is transmitted to the display for display.

[0028] Furthermore, the detection mechanism also includes a slide bar fixed on the upper surface of the column-mounted circuit breaker box, and a clamping rod fixed on the upper surface of the slide bar, and the upper surface of the detection box is provided with a mounting hole adapted to the clamping rod.

[0029] The beneficial effect of adopting the above further solution is that by providing a slide bar, it can be adapted to the slide groove at the edge of the detection box, so that the detection box can be easily hung on the edge of the column-mounted circuit breaker box to detect the entire device.

[0030] Compared with the prior art, the balance adjustment test device for magnetically controlled column-mounted circuit breakers integrating primary and secondary equipment has the following beneficial effects:

[0031] 1. The present invention is provided with an innovative detection mechanism, which can perform balance test, opening and closing time, opening and closing response speed and data flowing during closing on the circuit breaker, thereby ensuring the service life and safety detection of the circuit breaker on the magnetic control column. When the magnetic control mechanism pushes the moving contact and the static contact to perform opening and closing operations, it can simultaneously drive the contact rod to contact the contact sensor, thereby calculating the contact time and the number of contacts and converting them with the start-up time, thereby calculating the opening and closing response speed and the opening and closing time.

[0032] 2. The present invention sets a current detection component. Before closing the circuit, the outlet terminal is connected to the current detector through a line, so that the current can be transmitted to the current detector when closing the circuit. The controller calculates these data to obtain parameters such as closing current, so as to ensure the accuracy and reliability of its measurement, control, protection and other functions.

[0033] 3. The present invention sets a pole mechanism, etc., and when performing a closing operation, firstly, the insulating push rod is pushed up by the magnetic control mechanism, so that the insulating push rod pushes the moving contact to rise in the vacuum arc extinguishing chamber, and the moving contact approaches the static contact during the rise. As the moving contact approaches the static contact, the current shrinks to a point where the contact just approaches. At this time, the resistance increases sharply and the temperature rises rapidly. Metal vapor evaporates from the contact surface at high temperature, resulting in extremely strong gap breakdown and generating a vacuum arc, which is then quickly extinguished and the current is suppressed by the vacuum arc extinguishing chamber. The working principle is the same when opening the switch. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0044] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0045] As described in the background technology, the structure of the magnetically controlled column-mounted circuit breaker is relatively complex, and it is not convenient to detect and record the parameters of the number of opening and closing times, closing time, opening and closing response speed, and closing current of the circuit breaker. For this reason, the present embodiment provides a balance adjustment test device for a magnetically controlled column-mounted circuit breaker that integrates primary and secondary equipment. The device can not only facilitate the testing of the balance, opening and closing time, opening and closing speed, and closing current of the magnetically controlled column-mounted circuit breaker, but also has an extremely simple installation method, and can also be tested after the magnetically controlled column-mounted circuit breaker is installed on the column.

[0046] See also Figure 1 - Figure 7This embodiment proposes a balance adjustment test device for a magnetically controlled column-mounted circuit breaker with integrated primary and secondary devices, including a column-mounted circuit breaker box 1, a pole body 2 fixedly connected to the upper surface of the column-mounted circuit breaker box 1, and a pole mechanism 3 located inside the pole body 2, the pole mechanism 3 including a static contact 302 fixed to the inner top wall of the pole body 2, and a moving contact 303 directly below the static contact 302, and an insulating push rod 307 fixedly connected to the lower end of the moving contact 303.

[0047] In this embodiment, by setting the static contact 302 and the moving contact 303, when closing the circuit, a large number of vacuum arcs will be generated at the moment when the moving contact 303 contacts the static contact 302. At this time, the vacuum arc can be quickly extinguished and the current can be suppressed through the components in the pole mechanism 3.

[0048] As an implementation method, the pole mechanism 3 also includes a vacuum interrupter 301 fixed to the inner wall of the pole body 2 and located outside the static contact 302, the lower end of the moving contact 303 slides through the vacuum interrupter 301 and is fixedly connected to a connecting line 304, the outer surface of the pole body 2 is fixedly connected to a current transformer 305, and the interior of the current transformer 305 is fixedly connected to a conductive rod 306 connected to the outer end of the connecting line 304.

[0049] In this embodiment, a current transformer 305 is provided. The current transformer 305 includes a magnetic core, a coil and an inductor. The coil is wound around the magnetic core. The inductor senses the electromotive force and converts it into a corresponding electrical signal output to provide reliable measurement data.

[0050] By setting up the vacuum interrupter 301, the shell of the vacuum interrupter 301 adopts an airtight insulating shell made of glass or ceramic. Through the excellent insulation of the vacuum in the tube, the medium and high voltage circuit can quickly extinguish the arc and suppress the current after the power is cut off, avoiding accidents and unexpected events.

[0051] As an implementation manner, the pole mechanism 3 also includes an insulating protective tube 308 fixed on the outer surface of the insulating push rod 307, and a fixing ring 309 fixedly connected to the inner bottom wall of the pole body 2, and the upper surface of the fixing ring 309 is fixedly connected to an overtravel spring 3010 sleeved on the outer surface of the insulating push rod 307.

[0052] In this embodiment, an insulating protective tube 308 is provided, which mainly protects the insulating push rod 307 to prevent the insulating push rod 307 from being damaged by electric current. The overtravel spring 3010 can ensure the contact pressure after the static contact 302 contacts the moving contact 303, thereby ensuring good contact of the switch.

[0053] As a supplement, the overtravel spring 3010 can provide elastic force after the moving contact 303 contacts the static contact 302, so that the moving contact 303 and the static contact 302 can be in close contact, thereby avoiding a gap between the contacts that affects the current transmission after closing.

[0054] A magnetic control mechanism 4 connected to the insulating push rod 307 is arranged inside the pole-mounted circuit breaker box 1. The magnetic control mechanism 4 includes a contact rod 4010 that slides with the inner wall of the pole-mounted circuit breaker box 1, and a fast transmission assembly connected to the contact rod 4010. The magnetic control mechanism 4 is used to push and pull the moving contact 303 and the static contact 302 through the insulating push rod 307 to quickly open and close the circuit.

[0055] In this embodiment, by setting up the magnetic control mechanism 4, not only can the insulating push rod 307 be pushed or pulled by the unique magnetic push of the magnetic control mechanism 4, but also the moving contact 303 can be driven to move upward or downward, so that the moving contact 303 contacts the static contact 302, thereby realizing the opening and closing operation. In addition, during the opening and closing operation, the reaction speed of the opening and closing can be improved and the response time can be reduced through the rapid transmission component, and the contact rod 4010 can be driven to connect with the subsequent detection device, so as to realize the detection of the number of opening and closing and the opening and closing response time.

[0056] As an implementation method, the magnetic control mechanism 4 also includes a commutator 401 fixed on the inner bottom wall of the column-mounted circuit breaker box 1, and a magnetic column 402 fixed on the output end of the commutator 401, the upper surface of the magnetic column 402 is fixedly connected to a slide rod 403, the outer surface of the slide rod 403 is slidably matched with a magnetic ring 404 fixedly connected to the lower end of the insulating push rod 307, and the outer surface of the slide rod 403 is slidably connected to the reserved hole at the lower end of the insulating push rod 307.

[0057] In this embodiment, by setting a commutator 401, the commutator 401 passes a positive pulse current to change the magnetic field transformation of the magnetic column 402, so that the magnetic column 402 can attract or repel the magnetic ring 404, so that the insulating push rod 307 can be pushed to make the moving contact 303 contact or separate with the static contact 302, thereby realizing the operation of opening and closing the switch.

[0058] As an implementation method, the rapid transmission assembly includes two transmission plates 405 hinged to the protrusions on the outer surface of the magnetic ring 404, and a fixed rod 406 fixed to the inner wall of the column-mounted circuit breaker box 1, a slidable ring is provided on the outer surface of the fixed rod 406 and is hinged to the outer end of the transmission plate 405, a first telescopic spring 407 is sleeved on the outer surface of the fixed rod 406, and a second telescopic spring 408 is installed between the two transmission plates 405 through the protruding rod.

[0059] In this embodiment, by providing a rapid transmission component, it is possible to facilitate the magnetic ring 404 to drive the transmission plate 405 to slide under the limiting action of the fixed rod 406 under the action of attraction or repulsion between the magnetic column 402 and the magnetic ring 404, and the response speed when closing the switch can be improved through the action of the first telescopic spring 407 and the second telescopic spring 408.

[0060] As an implementation manner, the magnetic control mechanism 4 also includes two hinged plates 409 hinged to the protrusions on the outer surface of the magnetic ring 404, and the outer ends of the hinged plates 409 are hinged to the contact rod 4010. The hinged plates 409 are used for the magnetic control mechanism 4 to drive the contact rod 4010 to extend and retract at the pole-mounted circuit breaker box 1 when the control pole mechanism 3 is opened and closed.

[0061] In this embodiment, by providing a hinged plate 409, when the magnetic ring 404 moves up and down to open and close the switch, the hinged plate 409 can drive the contact rod 4010 to slide under the limiting action of the pole-mounted circuit breaker box 1, so that the contact rod 4010 can slide and retract outside the pole-mounted circuit breaker box 1, so that the contact rod 4010 contacts the contact sensor 703, so that the number of opening and closing, the opening and closing response speed and the opening and closing time can be recorded.

[0062] As an implementation method, an outgoing terminal 5 is installed at the outer end of the conductive rod 306 , and an incoming terminal 6 is installed at the upper end of the static contact 302 .

[0063] In this embodiment, by providing the outgoing terminal 5 and the incoming terminal 6, the connection and transmission of the line can be facilitated.

[0064] The beneficial effect of adopting the above further scheme is that a detection mechanism 7 connected to the contact rod 4010 is arranged outside the pole-mounted circuit breaker box 1, and the detection mechanism 7 includes a detection box 701 installed on the outside of the pole-mounted circuit breaker box 1, and a contact sensor 703 installed on the inner wall of the detection box 701 and facing the outer end of the contact rod 4010. The contact sensor 703 is used to detect the number and speed of opening and closing between the moving contact 303 and the static contact 302 by contacting with the contact rod 4010; the detection mechanism 7 also includes a horizontal detection component and a current detection component located inside the detection box 701.

[0065] In this embodiment, by setting up the detection mechanism 7, it is not only possible to facilitate the contact rod 4010 and the contact sensor 703 to contact each other through the mutual cooperation of the contact rod 4010, but also possible to make the contact rod 4010 contact the contact end of the contact sensor 703 when opening and closing the switch, so that the contact sensor 703 can record the number of opening and closing times, and the reciprocating operation can facilitate the testing of the service life of the entire device, and can also record the response speed when opening and closing the switch.

[0066] As an implementation, the detection mechanism 7 further includes a limiting cylinder 702 fixed to the inner wall of the detection box 701 and slidably matched with the contact rod 4010 , and the limiting cylinder 702 is used to ensure that the contact rod 4010 is in precise contact with the contact sensor 703 when sliding and retracting.

[0067] In this embodiment, by providing the limiting cylinder 702, the contact rod 4010 can be easily limited and slid, so that the contact rod 4010 can accurately contact the contact end of the contact sensor 703 when telescopically sliding at the column-mounted circuit breaker box 1, so that the contact sensor 703 can record the closing or opening of the moving contact 303 and the static contact 302. When the contact rod 4010 is tightly closed between the moving contact 303 and the static contact 302, the contact rod 4010 can only contact the contact sensor 703 at this time, thereby avoiding the situation where recording is made before closing.

[0068] As an implementation, the level detection assembly includes a support plate 704 fixed to the inner wall of the detection box 701, and a level detector 705 installed on the upper surface of the support plate 704, and the level detector 705 is used to detect the horizontal state of the pole-mounted circuit breaker on the pole.

[0069] In this embodiment, by setting up a horizontal detection component, it is possible to facilitate horizontal detection of the entire device, and to facilitate detection of whether the magnetically controlled column-mounted circuit breaker integrating the primary and secondary devices is in a horizontal state when installed on the column, thereby improving practicality and safety.

[0070] As an implementation method, the current detection component includes a current detector 706 installed on the inner wall of the detection box 701, and the connection end of the current detector 706 passes through the detection box 701 and extends to the upper part of the detection box 701. The detection mechanism 7 also includes a controller 707 installed on the inner wall of the detection box 701, and a display 708 installed on the outer surface of the detection box 701. The controller 707 is used to calculate, collect, transmit and record the detection data.

[0071] In this embodiment, by setting a current detection component, when the circuit breaker performs a closing current detection, the output terminal 5 and the connection end of the current detector 706 are first connected through the line. At this time, by opening and closing the circuit, the current can be transmitted to the current detector 706 for testing and recording, and the controller 707 is used for control and information transmission, and the current is transmitted to the display 708 for display.

[0072] The controller 707 uses a PLC programmable logic controller model, such as Siemens S7-1200 series or Mitsubishi FX3U series. The specific model is selected according to actual needs. The controller has powerful data processing capabilities and multiple input and output interfaces, and is suitable for complex industrial control environments.

[0073] As an implementation, the detection mechanism 7 further includes a slide bar 709 fixed on the upper surface of the column-mounted circuit breaker box 1 and a clamping rod 7011 fixed on the upper surface of the slide bar 709 . The upper surface of the detection box 701 is provided with a mounting hole 7010 adapted to the clamping rod 7011 .

[0074] In this embodiment, by providing the slide bar 709, it can be adapted to the slide groove at the edge of the detection box 701, so that the detection box 701 can be conveniently hung on the edge of the pole-mounted circuit breaker box 1 to detect the entire device, and by providing the clamping rod 7011, the stability of the detection box 701 hung on the pole-mounted circuit breaker box 1 can be further improved, and when the detection box 701 is hung on the edge of the pole-mounted circuit breaker box 1, it is necessary to align the contact rod 4010 with the limiting cylinder 702, so as to facilitate subsequent detection.

[0075] In addition, the current transformer 305, commutator 401, contact sensor 703, level detector 705, current detector 706, controller 707 and display 708 in the present invention are all conventional equipment purchased on the market and known to technical personnel in this field. The models can be selected or customized according to actual needs. The setting method, installation method and electrical connection method thereof only need to be debugged according to the requirements of the instruction manual, and will not be described in detail here.

[0076] The working principle of the present invention is as follows: when opening and closing the circuit breaker, the detection box 701 is first hung on the edge of the circuit breaker box 1 on the column through the installation hole 7010 and the clamping rod 7011, and the detection box 701 can be accurately hung on the contact rod 4010 through the limiting of the clamping rod 7011, so that the contact rod 4010 can enter the limiting cylinder 702, and at the same time, the magnetic control mechanism 4 is connected to the connection end of the current detector 706 through the line.

[0077] At this time, by passing a positive pulse current into the commutator 401, the commutator 401 changes the magnetic field of the magnetic column 402, so that the magnetic column 402 can push the magnetic ring 404 under the limiting action of the slide rod 403, and then the magnetic ring 404 drives the insulating push rod 307 to rise, and the insulating push rod 307 pushes the moving contact 303 to rise in the vacuum arc extinguishing chamber 301, so that the moving contact 303 contacts the static contact 302, thereby realizing the closing and opening operations.

[0078] During the opening and closing, the magnetic ring 404 can drive the contact rod 4010 to move through the hinge plate 409 during the lifting process, so that the contact rod 4010 can be extended and retracted in the pole-mounted circuit breaker box 1 and the limit cylinder 702. When the moving contact 303 contacts the static contact 302, the contact rod 4010 just contacts the contact sensor 703, so that the opening and closing can be recorded. The reciprocating operation can test the service life, opening and closing response speed, and opening and closing time of the pole-mounted circuit breaker. When closing, the current is transmitted to the current detector 706 through the magnetic control mechanism 4 for detection, so that the data is converted by the controller 707 to calculate the parameters of the closing current. When the pole-mounted circuit breaker is installed, the level detector 705 and the display 708 can cooperate with each other to display whether the circuit breaker is in a balanced state at all times.
