The sliding contact line current collector is the main device for picking up electrical energy on the current collection side in a sliding contact line system. It directly conducts electrical energy to the electrical equipment through the sliding contact between the collector brush and the guide rail, thereby achieving mobile power supply for the system. The sliding contact line current collector consists of two parts: a tension device with a mechanical structure and a collector brush that directly slides in contact with the guide rail. Sliding contact line current collectors, current receivers, power feeders, and conductors. Multi-pole sliding contact line current collectors, single-pole sliding contact line current collectors, single-pole row-type sliding contact line current collectors, and combined sliding line current collectors.
The safety sliding contact line current collector mainly consists of components such as the shoe piece, shoe box, spring, current collector bracket, and current collector support part. Current collectors are divided into heavy-duty and light-duty types. The choice between a light-duty and heavy-duty current collector is determined by the current of the sliding contact line. Generally, if the sliding contact line current is less than or equal to 500A, a light-duty current collector can be selected; if it is greater than 500A, a heavy-duty current collector should be used.
When selecting a safety slidingcontact line current collector, * the current collector should be considered from a manufacturer that matches the sliding contact line. Do not use current collectors indiscriminately, otherwise it will affect the normal operation of the crane, and in severe cases, it may burn out the sliding contact line. The shoe piece on the current collector is made of copper-containing carbon-based pressed material. After purchase, check the fit with the sliding line. Since the current collector itself is a consumable item, long-term use will wear the shoe piece, so it is necessary to regularly check the wear degree of the shoe piece on the current collector and replace it periodically.
