Outdoor high voltage multi-oil circuit breaker

The outdoor high-voltage multi-oil circuit breaker is a three-phase AC 50Hz high-voltage switchgear, which is suitable for power supply control of power equipment and power lines in urban or rural power systems with a rated voltage of 10KV. The circuit breaker can reliably combine load current, overload current and short circuit current.

Brief introduction of outdoor high-voltage multi-oil circuit breaker structure

The circuit breaker is a three-phase common-box oil-immersed structure with plug-in copper-tungsten contacts (1 type static head in one piece, type II static touch). The box is equipped with an overcurrent release and delay device, which can automatically trip when the network fails. Oil doubles as an arc extinguishing and insulating medium. The hand-operated mechanism is mounted on the front end of the lid and integrated with the switch. The wires are led through a porcelain sleeve that is fixed to both sides of the lid.

DW10-10II adopts anti-type porcelain sleeve and increases the outer insulation distance; the cover and the box are fully enclosed; the trip current can be adjusted in the mechanism cover without opening the box.
