High and Low voltage current collector

High and Low voltage current collector
Product Detailed
High and low voltage curret collector 1.easy operation 2.easy maintance 3.reliable working condition

1.  Function

SZ1-W10 High and Low Voltage Current Collector is special designed for using with WK-10 mining excavator which manufactured by TAIYUAN HEAVY INDUSTRY CO., LTD. It leads the feeder line of 3phase AC50Hz/6kv from under propel device to swing platform, then lead the step down AC voltage and the rectified DC power from swing platform to propel device.

2.Construction Features

The current-collector is comprised of encloser, carbon brush part, the Ring part and swing accessories.

The encloser encludes high voltage encloser and low voltage encloser. The low voltage encloser is fixed on the swing platform by bolt, the high voltage encloser is fixed on the ring of low voltage encloser by fastener; coverplate on the top.

The carbon brush part is comprised of end cover, isolation bearing, brush box and carbon brush. The carbon brush part is put on the end cover of the Ring, then connected with the encloser by pull rod at the middle; when the encloser revolve with the platform,, the carbon brush revolves together.

The Ring part is comprised of end cover, isolation sleeve, high voltage ring, earthing ring and low voltage ring. After the alignment of low voltage current-collector edge and the under frame edge, fix them on the centre pivot, the bottom plate of  high voltage current-collector and the top plate of low voltage current-collector fix tegether by fastener.

The swing accessories means the bottem board, the Ring and the encloser were fixed  on the bottom board during the transpotation.

When working, the Ring is fixed on the centre pivot, and the carbon brush part is towed to the sleeve by pull rod, then connect the pull rod on the platform. When the excavator swing, the carbon brush part together with the platform move around the Ring through the bearing. There is wire on top of the Ring and the carbon brush, under the condition of power on, transfer the current from the propel device to swing platform, or transfer the current from the swing platform to propel device.
