Mining Flameproof and Intrinsically Safe Dual Speed 2-Loop Vacuum Electromagnetic Starter

Mining Flameproof and Intrinsically Safe Dual Speed 2-Loop Vacuum Electromagnetic Starter

 Mining flameproof and intrinsically safe 2-loop vacuum electromagnetic starter

Main software

  QJZ-2×200/1140(660)S Mining explosion-proof and intrinsically protected two-loop vacuum electromagnetic starter (hereinafter referred to as the starter) is applicable to the coal mine underground. In the AC 50Hz voltage 1140V or 660V line, management the commence and cease of mine explosion-evidence 3-phase asynchronous motor, which has two circuit impartial handle operate, double circuit water amount computerized management operate, and double circuit joint management function. At the same time, in accordance to the low h2o level, substantial h2o level, and ultra-high drinking water level probes, one # circuit can realize computerized operation in the pumping approach, due to the fact the drinking water flow rises to the ultra-higher drinking water level probe, two # circuit can realize the double circuit simultaneous drainage operate.
