Direct-acting isolating switch

Abstract

The invention discloses a direct-acting isolating switch. The direct-acting isolating switch comprises a switch base, two switch supporting seats which are in bilateral symmetry are fixed to the upper end face of the switch base, switch sliding seats are arranged in the switch supporting seats, arc baffle mechanisms are arranged in the switch sliding seats, and a moving contact mechanism is arranged in the switch sliding seat on the left side. The switch sliding seats on the left side and the right side are away from each other or close to each other at the same time, so that opening and closing of the isolating switch are achieved, friction between a moving contact and a static contact is reduced to the maximum extent, abrasion of the moving contact and the static contact is reduced, and the service life of the switch is prolonged; and meanwhile a left cover plate and a right cover plate are in a vertical state after opening, the left cover plate blocks the moving contact, and the right cover plate blocks the static contact, so the generation of electric arc between the moving contact and the static contact is reduced, and the generation of flashover is prevented from generating danger to operators.

Description

technical field [0001] The invention relates to the technical field of power switches, in particular to a direct-acting isolating switch. Background technique [0002] The isolating switch is a switching device that is mainly used to "isolate power supply, switch operation, connect and cut off small current circuits", and has no arc extinguishing function. [0003] The current isolating switch is generally a rotary type. During the process of switching the switch, the moving contact will rub against one side of the static contact. Under long-term use, if the moving contact and the static contact are severely worn, the isolation will be affected. The conductivity between the switches affects the normal use of the switch. At the same time, because the current isolating switch has no arc extinguishing device, an arc will be generated during the opening and closing of the isolating switch. Affect the safety of the working environment. Contents of the invention [0004] The o...
