Along with improving constantly of automation of transformation substations degree, unwatched transformer station is more and more many, and sulfur hexafluoride breaker is widely used in electric power system with its good performance.As the chief component of power transmission and transforming equipment, its effect is the safe operation that disconnects or connect circuit and protection major network.But, still following problem can often appear in use:
1, each parts of formation circuit breaker container have pore, sand holes and weld seam gas leak phenomenon;
2, the standstill seal place gas leakage of the employing of the interface between the parts;
3, movable part, special movable sealing are bad;
4, pneumatic line, pipe joint and valve leak gas.
We know that sulfur hexafluoride gas plays arc extinguishing and insulating effect in circuit breaker, if gas pressure descends and can not get in time replenishing, the arc extinguishing of sulfur hexafluoride gas and insulating capacity will descend so.If carry out breaking operation this moment, the accident of scaling loss or blast will take place.So, when the sulfur hexafluoride gas in the circuit breaker drops to a certain degree, just must replenish in time in right amount, to guarantee the normal operation of equipment.For a long time, the working method that people continue to use always is, when pressure reduces, sends the signalisation operations staff and carries out tonifying Qi or handle principal fault, and the operations staff reinforms the higher level and the maintainer handles then, and intermediate link is many, and is time-consuming.Because tonifying Qi has in time stayed hidden danger for the safe operation of equipment.
Summary of the invention
To be solved in the utility model is exactly in the prior art, the sulfur hexafluoride breaker tonifying Qi in time when leaking air phenomenon that is in operation, its insulation and arc extinction performance are greatly weakened, the problems such as hidden danger that cause the accident, and provide that a kind of structure is unique rationally, installation is simple, time saving and energy saving, reliability is high and can realize the new device of on-line automatic tonifying Qi.
Technical solution of the present utility model is to realize like this, the sulfur hexafluoride breaker automatic air supply device, comprise the sulphur hexafluoride gas tank, valve, Pressure gauge, gas pipeline, pressure-reducing valve, electromagnetically operated valve, non-return valve, safety valve, the Pressure gauge of live contact, joint and sulfur hexafluoride breaker, the top of gas pipeline is connected with the sulphur hexafluoride gas tank, valve and pressure-reducing valve are housed on the gas pipeline, Pressure gauge is contained between the import of valve and pressure-reducing valve, and and gas pipeline be connected, the outlet of pressure-reducing valve is connected with the import of electromagnetically operated valve, the outlet of electromagnetically operated valve is connected with the import of non-return valve, the outlet of non-return valve is connected with the joint that is contained in the gas pipeline end, the Pressure gauge of safety valve and live contact is housed respectively on the pipeline between non-return valve and the joint, and joint is connected with sulfur hexafluoride breaker.
Described parts can become one by segment set, also can all become one.
The characteristics of the utility model maximum are to have realized on-line automatic tonifying Qi, and are time saving and energy saving, and the generation of having stopped accident has improved the fail safe and the reliability of equipment, are specially adapted to the tonifying Qi operation of the sulfur hexafluoride breaker of the various models that power transmission and transforming equipment uses.
