Problems solved by technology

Its function is to reliably isolate the electrical equipment that needs to be overhauled from the live part of the power grid, so that the electrical equipment to be overhauled and the power supply have an obvious disconnection point. It is not really separated, and the maintenance personnel may touch the live parts and cause accidents. Therefore, we have designed an automatic isolating device for isolating switches to solve the above problems

Abstract

The invention discloses an automatic isolating device of an isolating switch, and relates to the technical field of isolation switches. The automatic isolating device comprising a device body, which comprises an operating shaft, a crank arm, a connecting rod, a movable hinge, an insulating partition plate, a fulcrum hinge and a limiting bracket, wherein the operating shaft is hexagonal, one end ofthe operating shaft is connected with a bevel gear, one end of the crank arm is a hexagonal hole, a first shaft pin is welded to the other end of the crank arm, two M5 threaded holes are formed in the two sides of the hexagonal hole, one side of the operating shaft penetrates through the hexagonal hole and is fixedly connected with the crank arm through the two M5 threaded holes, And a first through hole is formed in the lower end of the connecting rod. According to the invention, the moving and static knife heads of the isolating switch can be truly isolated only through several simple partsso as to avoid hidden dangers existing in products and improve the safety performance of equipment, so that the personnel safety reliability is guaranteed when the equipment is overhauled, and the automatic isolating device is suielectrode lugle for application and popularization.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to an automatic isolating device for an isolating switch. Background technique [0002] The isolating switch is a kind of high-voltage switch. Because there is no special arc extinguishing device, it cannot cut off the load current and short-circuit current. It is generally used in conjunction with a circuit breaker. Its function is to reliably isolate the electrical equipment that needs to be overhauled from the live part of the power grid, so that the electrical equipment to be overhauled and the power supply have an obvious disconnection point. There is no real separation, and maintenance personnel may touch the live parts and cause accidents. Therefore, we have designed an automatic isolating device for isolating switches to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior ar...
