The flame-proof reactive power compensator

Product Description

PURPOSE

The flame-proof reactive power compensator of the type MAR-KMB-… is designed for reactive power compensation in underground electricity networks with voltage up to 6 kV. They are adapted to work in non-methane and methane headings classified to “a”, “b” or “c” degree of methane explosion hazard and to the places classified to “A” or “B” class of coal dust explosion hazard.

GENERAL CONDITIONS OF USE

When used intrinsically safe control circuits and / or visualization and monitoring using relay control and / or communication modules, inductance and capacitance parameters control cables may not exceed the maximum specified for the type of equipment in the examination certificate WE type. Opening the lid of any can be done after turning off the power and close the earthing switch and the waiting for time required to discharge the capacitor bank. Compensator must be turned off in case of exceeding the permissible concentration of methane in the atmosphere.

CONSTRUCTION

The electrical system of the flame-proof mining switchgear is installed in the flame-proof housing. Housing has few separate chambers. Is installed on a chassis fitted with skids or wheels for transport to the place of installation of the switchgear on mine. The compensator consists of capacitors, apparatus for switching and control, contained in a common housing flameproof.
