Also comprise current transformer, the input of described current transformer is connected with the output of described circuit breaker; The output of described current transformer is divided into four the tunnel:
The first via is connected with voltage transformer by fuse;
The second the tunnel passes through ground switch earthing;
Ground connection after Third Road process electric capacity and display unit;
The four the tunnel passes through arrester ground.
Described current transformer adopts open type current transformer.
Described isolating switch adopts rotary separation switch.
Also comprise the observation window that is used for observing operating state in cabinet on the cabinet that is arranged on described gas-filling cabinet.
Described cabinet material adopts stainless steel, and thickness is 2.0mm.
Technique scheme of the present utility model compared with prior art has the following advantages:
(1) gas-filling cabinet described in the utility model, comprise bus unit, breaker unit and load cell, whole cabinet adopts modularized design, the perfect unity of and flexible expansion fixed with it, make the reliability that connects between bus unit, breaker unit and load cell improve, and adopt modularization to be convenient to assembling, also reduced to a certain extent cost and improved the space of load cell inside.Whole product has that volume is little, simple in structure, reliable, safety, maintenance is little, operating cost is low characteristics.
(2) gas-filling cabinet described in the utility model arranges mechanical locking device between circuit breaker and isolating switch, can effectively prevent misoperation, has improved the reliability of product work.
(3) gas-filling cabinet described in the utility model is provided with on cabinet for the observation window of observing operating state in cabinet, when element unstable working condition in cabinet or inefficacy, can watch easily by observation window, is convenient to the maintenance of product.
(4) gas-filling cabinet described in the utility model, described cabinet material adopts stainless steel, and thickness is 2.0mm, and stainless steel material is without burning, lower without explosion hazard and cost.
