Description
Technical field:
The utility model relates to a kind of gas charging system, is specially a kind of ring main unit and vacuumizes gas charging system.
Background technology:
Full Inflatable ring main unit is that live parts such as bus, on-load switch, fuse, circuit breaker are all sealed in the gas tank of ring main unit, is filled with the sulfur hexafluoride gas that purity reaches more than 99.9999% in gas tank; The good insulation utilizing high-purity sulfur hexafluoride gas to have and arc extinction performance, ensure short circuit interruption ability and the fail safe of ring main unit.Before sulphur hexafluoride is filled in gas tank, needs first the air in gas tank to be extracted out, make in gas tank, to reach 0.2 ~ 0.5 atmospheric vacuum degree.At present, air in gas tank is directly extracted out by general employing, and when the pressure in gas tank is lower than 0.5 atmospheric pressure, gas tank can produce larger distortion at atmosheric pressure, cause the section components displacement of installing in gas tank, to cause point, close a floodgate not in place or stuck; Time serious, the partial seal of gas tank is destroyed, the sealing of gas tank is caused to decline, produce leakage phenomenon, make the purity of sulfur hexafluoride gas in gas tank and moisture not reach standard-required, the serious accident of insulation breakdown, even gas tank blast very easily occurs when being short-circuited or be struck by lightning.
For solving the problem, Some Enterprises sets up reinforcement on the gas tank of ring main unit, and this can alleviate the distortion of gas tank, but does not fundamentally change gas tank produces distortion phenomenon when vacuumizing, and also add the manufacturing cost of ring main unit.
Summary of the invention:
The purpose of this utility model is to provide a kind of ring main unit to vacuumize gas charging system, above-mentioned in the direct process that the gas tank of ring main unit is vacuumized to solve, when gas tank internal pressure is lower than 0.5 atmospheric pressure, gas tank produces the problem of moderate finite deformation at atmosheric pressure.
To achieve these goals, the utility model adopts following technical scheme:
Ring main unit vacuumizes gas charging system, comprises vacuum storehouse, vacuum plant and aerating device; The warehouse in vacuum storehouse is provided with import, in import, door is installed, be provided with sealing strip between door and warehouse, warehouse be also provided with pressure vacuum ga(u)ge, ring main unit extraction valve, vacuum storehouse extraction valve and vacuum storehouse intake valve, ring main unit extraction valve be connected with the wireway stretched in vacuum storehouse; Vacuum plant comprises vacuum pump, and vacuum pump connects ring main unit extraction valve and vacuum storehouse extraction valve by exhaust tube; Aerating device comprises sulphur hexafluoride steel cylinder, and sulphur hexafluoride steel cylinder connects wireway by gas-filled tube, and gas-filled tube is provided with inflation adjuster valve and plenum gauge.
When the utility model ring main unit vacuumizes gas charging system work, first ring main unit to be inflated is advanced in vacuum storehouse, wireway is inserted the charge valve of ring main unit, shut door, close vacuum storehouse intake valve and inflation adjuster valve, open ring main unit extraction valve and vacuum storehouse extraction valve, then vacuum plant is started, air in vacuum storehouse and in ring main unit gas tank is extracted out, when the vacuum degree of taking seriously in hole capital after selling all securities and ring main unit gas tank reaches setting, close vacuum pump, close ring main unit extraction valve and vacuum storehouse extraction valve; Open inflation adjuster valve and vacuum storehouse intake valve, sulfur hexafluoride gas is made to be injected in the gas tank of ring main unit by gas-filled tube, in air Injection vacuum storehouse, regulate inflation adjuster valve and vacuum storehouse intake valve, make the difference of the pressure in the pressure in ring main unit gas tank and vacuum storehouse remain in setting range; When hole capital after selling all securities internal pressure of taking seriously is consistent with atmospheric pressure, opens door, continue to inflate in ring main unit gas tank, when gas loading pressure reaches setting, close inflation adjuster valve, wireway is extracted charge valve, will the ring main unit pull-out vacuum storehouse of inflation be completed.
Adopt the utility model in the process of ring main unit filling sulphur hexafluoride, because ring main unit is placed in vacuum storehouse, in the process that the gas tank of ring main unit is vacuumized, gas tank internal pressure is equal with external pressure, avoid in the process directly gas tank vacuumized, when gas tank internal pressure is lower than 0.5 atmospheric pressure, gas tank produces the problem of moderate finite deformation at atmosheric pressure, ensure that the quality of ring main unit.
The utility model ring main unit vacuum storehouse vacuumized in gas charging system can adopt following measures to guarantee that it can bear the negative pressure when vacuumizing: 1, the warehouse in vacuum storehouse is set to circular arc; 2, warehouse adopts and adds steel plate making; 3, the measures such as reinforcement are set on warehouse, in the prior art, except above-mentioned measure, also have other measure can ensure that the warehouse in vacuum storehouse all can bear vacuum degree 0.2 ~ 0.5 atmospheric negative pressure, do not repeat them here.
Adopt ring main unit to vacuumize the gas tank of gas charging system to ring main unit to vacuumize, avoid the distortion setting up reinforcement to reduce or avoid gas tank on the casing of gas tank, a set of ring main unit vacuumizes gas charging system and can vacuumize and inflate by the continuous gas tank to ring main unit in a pipeline fashion, reduces the overall manufacturing cost of ring main unit.
Further, in the bottom of warehouse, roller is installed, facilitates the movement in vacuum storehouse, make sulphur hexafluoride vacuum inflation system vacuumize ring main unit easily and to inflate.
Further, the import in vacuum storehouse is arranged on the sidewall of warehouse, is provided with springboard in the lower end of import, and after installing springboard, ring main unit can be pushed in vacuum storehouse along springboard.
