Mining explosion-proof intrinsic safety type control box for valve electric device

Abstract

The invention relates to the technical field of control boxes, in particular to a mining explosion-proof intrinsic safety type control box for a valve electric device, which comprises a power module and a transformer. The mining explosion-proof intrinsic safety type control box for the valve electric device is characterized in that: the transformer is connected with an isolating conversion switchand an electric leakage protection module; the isolating conversion switch is connected with a fuse; the fuse is connected with a motor breaker; the motor breaker is connected with an alternating current contactor; the alternating current contactor is connected with an explosion-proof motor; the electric leakage protection module is connected with an intrinsic safety isolating module, a potentiometer and a control module; the intrinsic safety isolating module and the potentiometer are connected with the control module; the intrinsic safety isolating module is connected with a knob switch; theknob switch is connected with the power module and the control module; the control module is connected with a travel switch and a liquid crystal display; the travel switch is connected with a torque switch; and the torque switch is connected with the control module. The mining explosion-proof intrinsic safety type control box for the valve electric device can be applied to an automatic system more widely and more reliably.

Description

technical field [0001] The invention relates to the technical field of control boxes, in particular to a mine-used explosion-proof and intrinsically safe valve electric device control box. Background technique [0002] In recent years, with the improvement of the automation level of coal mines, manual valves have been difficult to adapt to the needs of modern technology development, and manual valves cannot detect whether there is leakage in the valve. In case of short circuit, overload, undervoltage, over torque, etc., remote control cannot be performed, and the use effect is not good. Contents of the invention [0003] In order to overcome the deficiency that the existing manual valves cannot meet the requirements of mine automation, the invention provides a mine flameproof and intrinsically safe valve electric device control box. [0004] The technical solution adopted by the present invention to solve the technical problem is: a mining explosion-proof and intrinsicall...
