The invention discloses a rectangular-rail electromechanical interlock explosive-proof switch which mainly comprises a connecting box, an electromechanical interlock box and a connecting protecting box. The connecting box, the electromechanical interlock box and the connecting protecting box are sequentially fixed together through three junction screws. The electromechanical interlock box comprises an electromechanical interlock box casing, a first explosive-proof guiding part, a second explosive-proof guiding part, a third explosive-proof guiding part, an explosive-proof partition plate, a main control lock rod, a first insurance lock rod, a second insurance lock rod, a first travel switch, a second travel switch and an explosive-proof line passing bolt. The electromechanical interlock box casing is integrally cast with the first explosive-proof guiding part, the second explosive-proof guiding part, the third explosive-proof guiding part and the explosive-proof partition plate. The rectangular-rail electromechanical interlock explosive-proof switch uses the electromechanical interlock device to control a circuit to be switched on and off, so that logically, the problem of confirming power off before the explosive-proof casing is opened is solved, and the purpose that the power cannot be switched in the open state of the explosive-proof casing is achieved. Furthermore, the rectangular-rail electromechanical interlock explosive-proof switch is convenient and quick to operate, greatly improves safety operation coefficients in the explosive-proof environment and improves labor productivity.
Description
technical field [0001] The invention relates to a switch, in particular to a rectangular rail electromechanical interlocking explosion-proof switch. Background technique [0002] 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 [0003] The technical problem to be solved by the present invention is to provide a rectangular-gauge electromechanical interlocking explosion-proof switch so as to safely, quickly and conveniently control circuit power in an explosion-proof environment. [0004] The technical solution of the present invention to solve the technical problem is: a rectangular ...
