Description
Technical field
It the utility model is related to equipment for power transmission and distribution technical field, more particularly to a kind of gas-filling cabinet.
Background technology
Gas-filling cabinet possesses numerous advantages compared with general ring main unit.It is primarily due to the compressed gas using excellent performance
(such as SF6 gases), substantially increases insulating properties, and compressed gas insulation performance is for 2-3 times of air and with voltage class
Rise, advantage is more obvious.Because this advantage is easy to design less cabinet size, be advantageous to miniaturization；Secondly
Due to the compressed gas using excellent performance, moreover it is possible to improve arc extinction performance；Again due to using closed structure, therefore not by outer
The influence of the environment (such as condensation, filth, toy and chemical substance) on boundary, available for severe place.Such as moral in 2002
State is spread unchecked in Elbe, and gas-filling cabinet part is flooded but to be restored electricity quickly, and this fully demonstrates gas-filling cabinet is not influenceed by adverse circumstances
The characteristics of.Further, since using non-maintaining product structure, maintenance work is greatly reduced, reduces maintenance cost.
The structure of gas-filling cabinet in the market mostly goes back Shortcomings, and still having can improvements.
In view of disadvantages described above, reasonable in design the utility model proposes a kind of gas-filling cabinet, above-mentioned ask can effectively solve the problem that
Topic, makes it more for practicality.
Utility model content
The defects of in order to overcome above-mentioned prior art, the purpose of this utility model are to provide a kind of gas-filling cabinet.
The utility model takes following technical scheme to realize：Gas-filling cabinet, including cabinet.The cabinet includes upper envelope
Plate, lower shrouding, left shrouding and right shrouding.Interior gas tank is provided with the cabinet.The interior gas tank outer wall and the upper sealing plate,
Lower shrouding, left shrouding, the inwall of right shrouding form outer gas tank.Cabinet side outer wall is connected to by vacuum lead to be taken out very
Empty pump.Detection means is provided with the vacuum lead.The cabinet lower end is provided with control room.It is provided with the control room
Vacuum circuit breaker, pressure release passage and cable.The cable jacket is equipped with current transformer.The vacuum circuit breaker and Current Mutual Inductance
Cable insulator is provided with cable connection between device.The pressure release passage is communicated in the outer gas bottom end and the pressure release
Passage is provided with explosion-protection equipment with outer gas tank junction.The cabinet is provided with pressure gauge with vacuum lead phase the same side.Institute
State cabinet and the pressure gauge opposite side is provided with inflation inlet.
Further, SF6 gases are filled with inside the outer gas tank.
Further, SF6 gases are filled with inside the interior gas tank.
Further, the SF6 gas concentrations of filling are more than the SF6 gas of filling inside the interior gas tank inside the outer gas tank
Bulk concentration.
In summary, the utility model has the advantages that：The utility model is reasonable in design compact, and layout is closed
Reason, securely and reliably, inflation progress and monitoring gas replenishment process can be observed at any time, there is good using effect, wiring and connection behaviour
It is more convenient to make, and installation is firm, effectively reduces cost, is adapted to promote the use of.
