Explosion-Proof and Intrinsically Safe Dual Speed 2-Loop Vacuum Electromagnetic Starter for Coal Mine

 Mining flameproof and intrinsically secure two-loop vacuum electromagnetic starter

Main software

  QJZ-2×200/1140(660)S Mining explosion-evidence and intrinsically safe two-loop vacuum electromagnetic starter (hereinafter referred to as the starter) is relevant to the coal mine underground. In the AC 50Hz voltage 1140V or 660V line, manage the start off and cease of mine explosion-evidence 3-period asynchronous motor, which has two circuit impartial manage function, double circuit drinking water amount automated manage operate, and double circuit joint handle operate. At the very same time, in accordance to the low water amount, higher h2o degree, and ultra-higher drinking water degree probes, one # circuit can comprehend automated operation in the pumping procedure, simply because the drinking water movement rises to the ultra-high water amount probe, 2 # circuit can comprehend the double circuit simultaneous drainage perform.
