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-pole high voltage isolation switch comprising a clamping base. The two sides of the top part of the clamping base are symmetrically provided with insulators, and the top ends of the insulators are fixedly provided with contact bases, which are provided with locking plates. The middle part of the upper surface of the clamping base is provided with a shaft rod in an inserted manner, and the side wall of the shaft rod is provided with a pole driving device. Two S-shaped poles and two I-shaped poles are respectively used for connecting and disconnecting the locking plates, and conduction of current is effectively and stably controlled. By adopting cooperation between a driven fluted disc, a driving fluted disc, and a bevel gear shaft, the rotation directions of the S-shaped poles are opposite, and then the use of the isolation switch is facilitated. By using a rotating disc and an eccentric motion principle, the I-shaped poles are in a butt joint with corresponding contact blocks, and then a false connection phenomenon during the use of the single pole is effectively prevented. By disposing a limiting pin in a pin hole, a contact pin is effectively prevented from falling out of the pin hole.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment, in particular to a double-knife high-voltage isolating switch. Background technique [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 a virtual connection or disconnection of the line. Contents of the invention [0003] The purpose of the present invention is to provide a double-knife high-voltage isolating switch to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a double-knife high-voltage isolating switch, including a card holder, insulators are symmetrically installed on...
