Problems solved by technology

In order to completely eliminate the possibility of human misoperation, some users require that the operating power be provided only when a certain equipment is being repaired and operated, which requires separate power supplies for the DS side and ES side of the three-position mechanism. The manual interlock on the DS side of the three-position mechanism and the manual interlock on the ES side share the same power circuit, which cannot meet the operating conditions proposed by the user for separately providing power to the DS and ES.
At the same time, the existing three-station mechanism needs to open the side door of the mechanism during manual operation, causing inconvenience to the user for manual operation

Abstract

The present invention discloses a manual interlocking and locking device with a three-station mechanism control point-to-point function, which comprises a manual interlocking device mounted on a machine core side plate and a manual locking device mounted on a mechanism case. According to the present invention, firstly, an operating handle pushes an interlocking power-on driving lever to rotate, cams on the same shaft simultaneously rotate, the cams press an electromagnet to enable the electromagnet to be powered on and a microswitch carries out state conversion, so that the interlocking electromagnet is powered on to be picked up; and the handle is continuously inserted, the operating handle pushes an interlocking power-off driving lever to rotate, the cams on the same shaft simultaneously rotate as well and press the electromagnet to enable the electromagnet to be powered off and the microswitch carries out state conversion, so that the interlocking electromagnet is powered off and the interlocking electromagnet is avoided being burnt down due to continuous electrification in the manual operating process. A power supply loop of the interlocking electromagnet is connected with an interlocking part outside a mechanism and if the external interlocking condition is not met, the interlocking electromagnet is always in a no-power state and the operating handle cannot be inserted into the mechanism so as to implement an interlocking function.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of high-voltage electrical equipment, and relates to a medium-voltage isolating switch and a high-voltage grounding switch of a gas-insulated metal fully-enclosed combined electrical appliance (GIS), in particular to a manual interlock and locking device with a three-station mechanism controlling point-to-point functions. [0003] 【Background technique】 [0004] In order to realize the miniaturization of high-voltage electrical appliances, the operation of high-voltage disconnector (DS) and high-voltage earthing switch (ES) has been improved from two separate operating mechanisms to one The three-position operating mechanism is operated to realize three different switching states: isolating switch open, grounding switch open; isolating switch closed, grounding switch open; isolating switch open, grounding switch closed. In order to avoid human misoperation and ensure the safety of personnel and power...
