Problems solved by technology

[0002] The isolating switch is a switch that can carry the current under normal circuit conditions and the current under abnormal conditions within a specified time when the disconnector is in the off position. The common one is a single-knife isolating switch. The single-knife isolating switch is extremely easy to cause virtual connection or disconnection of the line.

Abstract

The invention discloses a double-knife high-voltage isolating switch comprising a base. Insulators are symmetrically mounted on both sides of the top of the base. Contact bases are fixedly mounted on the top ends of the insulators and are equipped with lock catch plates. A shaft rod is inserted into the middle of the upper surface of the base and the side wall of the shaft rod is provided with a knife driving device. Two S-shaped knives and two linear knives connect or disconnect the lock catch plates so as to effectively and stably control current conduction. Through the cooperation of a driven fluted disc, a driving fluted disc and a fluted shaft, the S-shaped knives rotate in the opposite direction to facilitate the use of the isolating switch. By using a rotary disc and using the principle of eccentric motion, the linear knives are connected with matched contact blocks so that a phenomenon of virtual connection is avoided when a single knife is used. A stopping pin is installed at pin hole so as to effectively prevent a contact pin from falling from the pin hole.

Description

Technical field [0001] The invention relates to the technical field of heavy current equipment, in particular to a double-blade high-voltage isolating switch. Background technique [0002] The isolating switch is the switch that meets the required insulation distance and obvious disconnection mark between the contacts when in the open position; when in the closed position, it can carry the current under normal loop conditions and the current under abnormal conditions within the specified time Equipment, while the ordinary single-blade isolation switch, the single-blade isolation switch is extremely easy to cause the virtual connection or open circuit of the line, and it is unstable in use and the isolation effect is not good. For this purpose, a double-blade high-voltage isolation switch is provided. Summary of the invention [0003] The purpose of the present invention is to provide a double-blade high-voltage isolating switch to solve the problems raised in the background art. ...
