EBZ75型掘進機電控系統(EBZ75、 EBZ55采用一套電控系統)

KX B2—100 /1140(660) E electrical control box is the core of the electronic system of EBZ55 and EBZ75, it is mainly responsible to keep the motor and the system to work normally, including motor start and stop operation and protection when overload, phase failure, short circuit, leakage, etc.

The entire electronic control system is mainly made from explosion-proof and Intrinsically Safe Electromagnetic Starter, besides it also includes explosion-proof bell, the mining explosion-proof lamps. The system structure is compact, small footprint, easy maintenance, and can be equipped with explosion-proof lighting (light emitting diode LED) which is independently developed by Shijiazhuang Coal Mining Machinery Co., Ltd. with high luminous efficiency (which is eight times that of incandescent), long life (5-10 million hours), good seismic performance, the lighting has applied for national patents.

Suitable working condition:
(1)ambient temperature:-5℃~+40℃;
(2)place away from dropping water
(3)Air pressure: 80kPa~110 kPa;
(4)Relative humidity:≤95%( +25℃);
(5) without gas which damage insulation or steam
(6) The tilt angle of mounting is not more than 16°
(7) Underground coal mine with gas or coal dust.
