The beneficial effects of the utility model:
The compact conformation floor space is little.
The sulfur hexafluoride gas use amount is few, and is therefore also little to the adverse effect of environment.
Because be modularized design, this high-voltage switch gear can change compound mode according to the actual conditions of transformer station with suiting measures to local conditions, has adaptable advantage, can according to user's busbar drawing prepare take up an area of little, in light weight, flexibility is good, indoorly can both be suitable for outward, customer satisfaction system primary cut-out; Insert for overhead transmission line and cable,, only need the bus access module is changed a little just and can be satisfied according to the different requirements that indoor and outdoors inserts; The transportation of this high pressure unit switch must whole Transporting be compared also greatly facility with switch in the past, and installation, maintenance is convenient, safe and reliable to operation.
