Description
Technical field
The utility model belongs to electric power application, relates to the SF that sulfur hexafluoride breaker, GIS combination electric appliance, six-component force balance transformer etc. use
6gas inflated, exhaust gas recovery, density meter effect instrument, use SF
6prevent because equipment SF when the inflation of (sulphur hexafluoride) air insulating device, blow off pressure adjustment
6density meter error cause equipment air chamber pressure too high or height.
Background technique
Pure sulfur hexafluoride gas be colourless, odorless, do not fire, nontoxic inert gas, there is good insulating property and arc extinction performance, its arc extinguishing energy force rate air is high 100 times, and therefore sulfur hexafluoride gas is widely used in novel SF 6 high-voltage circuit breaker, GIS combination electric appliance, six-component force balance transformer, six-component force balance sleeve pipe as insulating medium and arc-extinguishing medium.Because power equipment is in long-time running, affected by temperature change throughout the year, device fabrication element quality, many reasons such as connection part O-ring seal is aging unavoidably have deflation gas leak phenomenon that equipment air chamber pressure is reduced and SF
6density meter be in operation to divide by circuit breaker, the huge vibrations etc. that produce of closing a floodgate affect and damage and cause that metering is inaccurate to be reported by mistake.Above problem needs maintainer often to operating equipment tonifying Qi, venting in equipment runs, and makes SF
6density meter controls in acceptability limit.
Model utility content
The utility model to provide a kind of SF being exclusively used in sulfur hexafluoride breaker, GIS combination electric appliance, six-component force balance transformer etc.
6gas inflated, exhaust gas recovery, density meter effect instrument, can be SF
6the pressure adjusting of the inflation of (sulphur hexafluoride) air insulating device, venting.This instrument, can complete SF in running as effect while the equipment inflation of insulating medium and arc-extinguishing medium, exhaust sulfur hexafluoride gas safely, easily, easily
6whether density meter metering is accurate, avoids because of SF
6density meter error in dipping causes air chamber pressure too high or too low, substantially increases safe and reliable property.
The SF that the utility model relates to
6gas inflated, exhaust gas recovery, density meter effect instrument, comprise the sebific duct with rubber hose coupling, reduction valve and the equipment gas-charging connection be connected with reduction valve, and the other end self-sealing joint of sebific duct, its special way is: this SF
6gas inflated, exhaust gas recovery, density meter effect instrument are also provided with four-way link, and first port of described four-way link is connected with the rubber hose coupling of described sebific duct, and second port of described four-way link is connected to standard SF
6density meter, the 3rd port of described four-way link is connected with venting valve, and the 4th port of described four-way link is connected with reduction valve.
The beneficial effects of the utility model are as follows:
1, SF is used
6charge, exhaust of carrying out gas inflated, exhaust gas recovery, density meter effect instrument reclaims operation directly by equipment air chamber SF
6gas pressure adjusts to the rated pressure of needs.
2, by the standard SF on this special tool
6the SF that the pressure of density meter to equipment air chamber monitors and equipment carries
6density meter both can have been eliminated effect provides inflatable tool because of SF by producer
6density meter error (due to workmanship or the reasons such as damage that are in operation filling, exit time and make equipment air chamber pressure too high or too low) thus in avoiding running equipment there is the defect that unnecessary fault occurs.
3, SF is connected to by special tool drain tap when air chamber pressure is too high
6gas reclaims by gas concentration unit.
4, this special tool easy and simple to handle, reduce operation easier, and repair quality and maintenance craft can be ensured.Convenient and swift, greatly shorten the repair time, increase work efficiency, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is this SF
6the structural representation of gas inflated, exhaust gas recovery, density meter effect instrument.
In figure: 1-rubber hose coupling, 2-sebific duct, 3-self-sealing joint, 4-standard SF
6density meter, 5-exits valve, 6-equipment gas-charging connection, 7-four-way link.
Embodiment
As shown in the figure, the SF that relates to of the utility model
6gas inflated, exhaust gas recovery, density meter effect instrument, comprise the sebific duct 2 with rubber hose coupling 1, the other end self-sealing joint 3 of sebific duct, this SF
6gas inflated, exhaust gas recovery, density meter effect instrument are also provided with four-way link 7, and first port of described four-way link 7 is connected with the rubber hose coupling 1 of described sebific duct 2, and second port of described four-way link 7 is connected to through the qualified standard SF of periodic test
6density meter 4,3rd port of described four-way link 7 is connected with venting valve 5, by connecting outlet pipe, sulfur hexafluoride gas is drained into sulphur hexafluoride recovering device during use, 4th port of described four-way link 7 is connected with equipment gas-charging connection 6, the replaceable each producer of described equipment gas-charging connection 6 (comprise GIS combination electric appliance and adopt sulfur hexafluoride gas to be insulating medium various model circuit breaker) various model device charging valve.
Operating procedure:
1, the equipment gas-charging connection 6 of this effect instrument to be connected with gas cylinder by reduction valve and to tighten.
2, open self-sealing joint 3, firmly back down needle, slowly open gas cylinder, adjustment reduction valve makes gas pressure in applicable pressure range, so that the gas of draining in effect instrument.
3, the self-sealing joint top cover that equipment of opening carries and SF
6self-sealing joint 3 docking of gas inflated, recovery, density meter effect instrument is tightened, observation caliber SF6 density meter 4 and SF on equipment
6whether density meter numerical value is consistent, to SF on equipment
6density meter verifies, as inconsistent inflation is changed afterwards in time.
4, slowly open reduction valve, adjustment reduction valve fills SF
6gas is to rated pressure (being shown by standard density meter), as air chamber pressure exceed rated pressure then slowly open venting valve 5 make air chamber pressure be down to rated pressure close gas cylinder valve, disconnect, the equipment self-sealing joint top cover opened and effect instrument self-sealing joint top cover are sealed, completes charge, exhaust operation.
In sum, this fill, venting instrument not only can low to equipment pressure in running time inflation, the venting of pressure height reclaim also have before filling, exit and fill, SF in effect operation in deflation course
6whether density meter metering is accurate, and avoiding producer provides inflatable tool at SF
6density meter due to workmanship or the reasons such as damage that are in operation filling, exit time and make the inaccurate too high meeting of (air chamber pressure is too high or too low) equipment air chamber pressure of equipment air chamber pressure cause air chamber burst disk action SF
6the line outage that gas leakage forces GIS combination electric appliance accident out of service to be powered, pressure reduces circuit breaker when reaching locking value and normally can not divide, close.Thus avoid equipment in operation that the generation of unnecessary fault occurs.
