Third-rail current collector

Operating principle, design of third-rail current collector

The current collector is contact with the supply rail(third rail) by collector slider, and the collector slider and third rail was coupled to transmit the power to the swing arm, then transmit the power in the cable to the electric equipment through the fuse box; the current collecting mode including top running, bottom running, side running etc.

According to the main insulation type, the current collector can be divided as rear panel insulation and arm insulation; according to the method of collector shoe away the third rail, the current collector including By the way of the main insulation can be divided into the main insulation can be divided into the backplane insulation, swing rod insulation of the two; by way of boots can be divided into: no shoes off operation, manual shoes, electric boots, pneumatic off the boots, Five kinds; At the same time, the boots can be divided into position detection and no position detection; position according to the fuse box can be divided into the overall position of the flow receiver and split type receiver.
