Mining flameproof and intrinsically secure two-loop vacuum electromagnetic starter
Primary software
QJZ-2×200/1140(660)S Mining explosion-proof and intrinsically secure 2-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, handle the start and quit of mine explosion-proof three-section asynchronous motor, which has two circuit unbiased management function, double circuit water level automated handle function, and double circuit joint manage purpose. At the same time, in accordance to the reduced water degree, large h2o degree, and ultra-large water level probes, one # circuit can comprehend automatic operation in the pumping process, simply because the drinking water circulation rises to the extremely-substantial drinking water level probe, two # circuit can recognize the double circuit simultaneous drainage purpose.
