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 twisted, etc., which makes the GW1-12 high-voltage isolating switch easy to be damaged and replaced frequently, so to a certain extent Increased cost of electrical maintenance

specific Embodiment approach

[0057]Specific implementation method: If there is no rust between the inverted T-shaped contact 8 and the sliding contact plate 21, when the cable where the isolating switch is located needs to be repaired, the high-voltage circuit breaker must be disconnected first, and then the isolating switch must be disconnected; when the isolating switch needs to be opened , the cable maintenance worker acts on the transmission device on the cable pole, so that the transmission device drives the rotating rod 57 on the disconnector to rotate; The rack 31 slides along the trapezoidal slot 48 on the pendulum block 46, and at the same time drives the rack 31 to swing around the central axis of the fourth pin 50 and gradually breaks away from the drive gear 28; the two return leaf springs 44 gradually release energy and return to their original shape, The drive rack 31 slides outwards from the second transmission groove 34 gradually; The direct interaction of the helical teeth 29; the driving...

Abstract

The invention belongs to the field of disconnector, in particular to a stable high-voltage disconnector, which comprises a base, a fixing notch, a first transmission groove, a first insulating ceramicpost, an inverted T-shaped contact, a second straight rack, a third straight rack, a fourth straight rack and the like, wherein two opposite side end faces of the base are respectively provided witha fixing notch. The upper end face of the base is provided with a first transmission groove; When it is necessary to disconnect the high voltage disconnector for cable maintenance, serious corrosion may occur between the inverted T-shaped contact and the sliding contact plate of the disconnector. A transmission the acts on a cable pole by a serviceman, a sliding contact plate slides slightly alonga first trapezoidal sliding groove on the conductive contact rod under the action of a transmission device on the cable rod. The inverted T-shaped contact is loosened and the corrosion is released, and then the high-voltage disconnector is easily turned off, so that the cable inspection and repair is carried out smoothly, the cable inspection and repair time is saved, and the danger caused by thefailure of the disconnector is avoided.

technical field [0001] The invention belongs to the field of isolating switches, in particular to a stable high-voltage isolating switch. Background technique [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 twisted, etc., which makes the GW1-12 high-voltage isolating switch easy to be damaged and replaced frequently, so to a certain extent This increases the cost of power maintenance. [0003] The present invention designs a stable high-voltage isolating switch to solve the above problems. Conten...
