Description

Technical Field

[0002] The high-voltage switches for power supply in underground coal mines are generally 10 kV or 6 kV. According to regulations, when inspecting switches or lines, after confirming the power outage, they must conduct electrical testing, discharge, three-phase short circuit and grounding before work is allowed on the line.

[0003] However, each time, the cover of the wiring compartment behind the switch must be opened, and a handheld high-voltage electrometer must be used to test the voltage, discharge the voltage, and connect the ground wire. After the inspection is completed, the ground wire must be removed and the cover must be replaced. Due to the limited space underground, the high-voltage switches are rigidly connected and placed close to the tunnel walls. The working space for performing the above operations is too small to directly observe whether the electrometer probe is touching the live object, or it is difficult to reach the ground wire. In addition, when the switch cover is opened and discharged, electric sparks may be generated, which is not conducive to work safety and efficiency, and even poses a serious safety hazard.

[0036] like Figure 5 As shown, the present invention also includes a control circuit. Various operations are centrally controlled by an intelligent controller 305. The controller is powered by a rechargeable battery E.

[0037] like Figure 6 As shown, the movement shifting mechanism includes a pushing mechanism 401, a connecting rod mechanism 402, a pull rod 403 and a rotating shaft 404. The pushing mechanism 401 is arranged at one end of the bottom of the movement frame 301. The first end of the connecting rod mechanism 402 is connected to the pushing mechanism 401 through the pull rod 403. The second end of the connecting rod mechanism 402 is connected to the rotating shaft 404. The rotating shaft 404 can be externally connected to an operating handle. A mechanical locking device 405 is provided between the rotating shaft 404 and the front door of the explosion-proof housing 1. The mechanical locking device 405 is used to lock or unlock the rotating shaft 404.

[0038] This embodiment can be implemented in two ways. The first is to implement it in the form of a dedicated discharge and grounding high-voltage switch connected in parallel with the high-voltage main switch. It needs to be installed in parallel with other switches. This is a fixed form and is used as a whole. The other is to implement it in the form of a movement body inserted into a universal high-voltage switch. This is a flexible form and can be used as a single movement. Both implementations can realize the automated operation of testing, discharging, and connecting the ground wire of a certain high-voltage line. The difference is that the latter requires first removing the movement of the circuit breaker for maintenance and then replacing it with the movement of the present invention.

[0039] When the circuit where the present invention is located needs to be shut down for maintenance, the maintenance circuit is shut down while the front door is opened to check whether the grounding clip is reliably connected to the device housing, whether the battery power is turned on and the power is supplied normally, and whether the internal components are intact and reliable. After confirming that everything is normal, the front door is closed, the mechanical locking device 405 is released, and when the external handle is pushed upward, that is, clockwise, about 15°, the inductive electroscope test switch 501 is turned on when it approaches the bottom sensing protrusion 503, and the electroscope test circuit in the controller 305 is triggered to start the electroscope test. At this time, if the test is normal, the "power on" indicator light on the indicator panel 306 in the window in front of the switch flashes quickly and a loud alarm sounds; then the "unlock" indicator light is on, the electromagnetic electroscope locking device 502 is attracted and opened, the lock is released, and the movement can continue to advance. Note that at this time, if the three-phase testers are all normal, the electromagnetic test locking device 502 can be opened and the handle can continue to be pushed; otherwise, as long as one phase tester 303 is abnormal, the electromagnetic test locking device 502 will not operate, the handle will not be able to continue to be pushed forward, the movement will not be able to move forward, and the next step cannot be performed.

[0040] When the electroscope 303 is normal, the external operating handle continues to push the shaft to rotate 45° clockwise. When it reaches 60°, the three-phase high-voltage plug column 304 contacts the terminal 2, which is the static contact of the three-phase main circuit. When the handle is pushed to 90°, the plug column 304 is fully inserted into the terminal 2 and contacts reliably. At this time, the mechanical locking device 405 locks the handle to keep the plug column 304 in reliable contact with the high-voltage static contact.

[0041] That is, when the external operating handle is pushed to rotate the shaft clockwise to 45°~60°, the electroscope begins to sense the electricity. When it is 60°~90°, the electroscope 5 performs contact electricity testing. That is, the electricity testing process lasts for 5~10 seconds.

[0042] When the controller 305 confirms that the three-phase static contacts are all without power, the relay J is briefly closed, the indicator light is on, and its contact J is also briefly closed, connecting the suction circuit of the discharge vacuum contactor KM1 and the discharge delay relay SJ. Figure 4The three-phase contact KM1 in the circuit is energized and begins to discharge through the resistor. At the same time, the energized delayed disconnect contact SJ1 remains closed, connecting the holding circuit and the discharge indicator D1 lights up. When the delay ends, that is, the discharge ends, the energized delayed disconnect contact SJ1 of the delay relay SJ is disconnected, KM1 and SJ are released without electricity, and the discharge circuit is disconnected.

[0043] When the discharge is finished and the time delay relay SJ is disconnected, its energized time delay closing contact SJ2 is briefly energized, connecting the energizing circuit of the grounding vacuum contactor KM2. KM2 is energized, and its auxiliary contact KM2 is closed, so that KM2 remains energized. Figure 4 The three-phase contact KM2 in the circuit is turned on, completing the main circuit grounding operation. At the same time, the grounding indicator D2 is on, indicating that the grounding is reliable and maintenance work can begin.

[0044] After confirming that all maintenance work is completed, unlock the mechanical locking device, pull the external operating handle counterclockwise to make the movement exit the grounding state, and lock the rotating shaft with the mechanical locking device. Hang the power outage prohibited operation sign to complete all maintenance tasks.

[0045] The second method of use:

[0046] When a power outage is required for maintenance on a circuit, the circuit is first shut down. The front door of the flameproof enclosure is then opened. The original mechanism of the switch to be powered off is replaced with the mechanism of the present invention. The indicator plate hanging from the mechanism frame is magnetically attached to a window in the flameproof enclosure's front cover to allow for observation of the device's operating status. The grounding clamp is securely connected to the flameproof enclosure. The battery power supply is checked to ensure proper operation, and the internal components are intact and reliable. Once this is confirmed, the front cover of the flameproof enclosure is closed, and the mechanical locking device is released.

[0047] Then perform the electrical testing, discharge and grounding operations in sequence (the operation method and working principle are the same as the first method).

[0048] After confirming that all maintenance work is completed, unlock the mechanical locking device, pull the external operating handle counterclockwise to make the movement exit the grounding state, and lock the rotating shaft with the mechanical locking device. Take out the movement, install the original switch movement into the switch, restore the original switch function, and complete all maintenance tasks.

[0049] Special note: Before starting each power outage maintenance work, the external grounding bolt of the high-voltage switch must be reliably connected to the grounding electrode using a special grounding wire.

[0050] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
