Problems solved by technology

[0002] At present, there are many traditional high-voltage disconnectors operating in the power system, and their quality, operation and maintenance directly affect the safe operation of the power system; due to the influence of many factors such as air pollution, manufacturing process, maintenance management, etc., The isolating switch has serious corrosion during operation, which leads to the failure of the isolating switch to reject the opening of the isolating switch, and then the parts are damaged, the connecting rod is bent, etc. After years of operation, the failure rate of the GW4 high-voltage isolating switch is relatively high , the replacement is frequent, which increases the cost of power maintenance to a certain extent

specific Embodiment approach

[0073]The specific embodiment: when there is no rust between the contact 29 and the second conductive plate 43 and the sliding contact plate 64, when the high-voltage isolating switch needs to be disconnected, the cable maintenance worker acts on the transmission device on the cable rod; the transmission device makes the swing rod 10 Swing occurs; the swing rod 10 drives the first rotary block 12 and the second rotary block 48 to rotate respectively through two insulating ceramic columns 2; because the elastic coefficient of the driving spring 63 is very large, the second conductive seat 38 is in the drive gear 51 Under the joint action of the swing rod 10, it rotates synchronously with the second rotary block 48; the spiral spring 22 acts on the first conductive seat 15, so that the first conductive seat 15 rotates; the contact 29 is connected with the second conductive plate 43 and The sliding contact plate 64 is separated; when the swing rod 10 swings 90 degrees under the ac...

Abstract

The invention, which belongs to the field of disconnecting switches, in particular relates to a high-voltage disconnecting switch comprising a bearing base mechanism, an insulating porcelain column, acontact mechanism and a conductive plate mechanism and the like. The bearing base mechanism is mounted on a cable rod and is connected with a transmission mechanism arranged at the cable rod. When the high-voltage disconnecting switch needs to be disconnected for cable maintenance, severe corrosion may occur between the contact of the disconnecting switch and a second conductive plate and a sliding contact pad, so that disconnection of the high-voltage disconnecting switch becomes difficult. The maintenance worker applies forces to the transmission device arranged at the cable rod; the sliding contact pad slides to a small extent along a trapezoidal chute under the action of the transmission device arranged at the cable rod and thus the corrosion is broken; and thus the high-voltage disconnecting switch is disconnected easily, so that the cable maintenance is carried out smoothly. Therefore, the cable maintenance time is saved; and the danger caused by the failure of the disconnectingswitch is eliminated.
