新型组合式隔爆型低压配电装置的研制

Research on New Type of Combination Explosion-Proof Low Voltage Power Distribution Equipment

采用模块化结构和集中控制技术,把8个馈电单元有机地组合在一起,组成煤矿井下使用的新型组合式隔爆型低压配电装置。它不仅具有可靠性高、抗干扰性强和完善的电压、电流保护功能,而且同时提供8路电源(相当于8台配电装置),大大缩小井下配电硐室的面积,减少矿井建井成本。

Introduces one new type of combination explosion-proof low voltage power distribution equipment used at underground mine,the equipment combines 8 feed units with the modular structure and integrated control techniques.It does not have high reliability,high anti-interfere,complete protection of voltage and current,but also can supply 8 branches（equals 8 feed devices） simultaneously,which reduces the floor area in mining transformer station and the cost.
