Product Introduction

Ring main unit is generally divided into air insulation and SF6 insulation. It is used for breaking load current, breaking short-circuit current and transformer no-load current, charging current of overhead line and cable line at a certain distance, which plays a control and protection role. It is an important switch equipment for ring network power supply and terminal power supply. In the cabinet, the load switch equipped with air insulation mainly includes gas producing type, compressed air type and vacuum type. The load switch equipped with SF6 insulation is SF6 type. Because SF6 gas is enclosed in the shell, the partition fracture formed by it is invisible. The load switch in the ring main unit generally requires three positions, i.e. cut off the load, isolate the circuit and be grounded. It is easy to realize three positions for gas production type, air compressor type and SF6 type load switch, while the vacuum interrupter can only be disconnected and cannot be isolated. Therefore, an isolating switch is added in front of the load switch in general vacuum load ring network switch cabinet to form isolation fracture.

Ring network cabinet is commonly known as SF6 load switch and SF6 load switch + fuse combination
