Rectangular rail electromechanical interlocking flame-proof switch

Abstract

The invention discloses a rectangular rail electromechanical interlocking flame-proof switch which comprises a wiring box, an electromechanical chain box and a wiring protection box. The wiring box, the electromechanical chain box and the wiring protection box are orderly fixed together by using three combination screws. The electromechanical chain box comprises an electromechanical chain box shell, an explosion-proof guide I, an explosion-proof guide II, an explosion-proof guide III, an explosion-proof clapboard, a main control lock rod, an insurance lock rod I, an insurance lock rod II, a travel switch I, a travel switch II, and an explosion-proof wire passing plug I. The electromechanical chain box shell, the explosion-proof guide I, the explosion-proof guide II, the explosion-proof guide III and the explosion-proof clapboard are casted into a whole body. The on and off of a circuit are controlled through an electromechanical interlocking device, the power cut in advance before opening an explosion-proof shell is theoretically confirmed, a condition that a power supply can not be connected when the explosion-proof shell is in an opened state is ensured, and the safety in an explosion-proof environment can be greatly improved.

Description

[0001] This application is a divisional application, the original application date: April 24, 2014, the original application number: 2014101650365, and the name of the invention is: a rectangular rail electromechanical chain explosion-proof switch. technical field [0002] The invention relates to a switch, in particular to a rectangular rail electromechanical interlocking explosion-proof switch. Background technique [0003] At present, ordinary switches cannot be directly used in places with explosion-proof requirements, and ordinary explosion-proof switches have high requirements for use conditions and users, which makes it extremely troublesome to flexibly disconnect the power supply of some circuits in explosion-proof environments, and is harmful to safety. The improvement of production and production efficiency has a great impact. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a rectangular-gauge electrome...
