Linkage switch

Abstract

The invention discloses a linkage switch. The linkage switch comprises a shell, wherein the interior of the shell is partitioned to a low-voltage cabin and a high-voltage cabin by an intermediate plate, two swinging rods are arranged in the high-voltage cabin, free ends of the swinging rods are connected with an inner wall of the shell via hinges, metal balls are fixedly arranged at the free endsof the swinging rods, a separator is arranged at a position of a middle line of the two swinging rods, rotation shafts are arranged at two ends of the separator, the rotation shafts are installed witha bearing seat in the shell in a matching way by a pair of bearings, the rotation shafts penetrate through the intermediate plate and the shell, and a pointer is fixedly arranged at an end part of each rotation shaft. The linkage switch employs a mode of low voltage to control high voltage, and electric shock of a person is prevented; with the adoption of dual swinging rods, rapid connection anddisconnection of high-voltage power are achieved; and moreover, the separator is additionally arranged, an inert gas is filled, arcing is effectively prevented, and a contact is prevented from being burnt.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to a linkage switch. Background technique [0002] With the development of industrial technology, more electric-driven equipment is stationed in factories, and most of them use high-voltage electricity as the main energy supply. There are problems such as electric shock and burning, and there are great safety hazards, which can easily cause problems such as fire in the factory building. Moreover, direct operation of high-voltage electricity has a great risk of electric shock, which is easy to cause industrial accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a linkage switch that uses low voltage to control high voltage to avoid electric shock to personnel, and uses double swing rods to realize fast closing and disconnecting of high voltage , and a separator is adde...
