Description
Technical field
It the utility model is related to a kind of aerating device, more particularly to a kind of sulfur hexafluoride breaker overhaul aerating device.
Background technology
Since sulfur hexafluoride gas has good insulation performance and arc extinction performance, its electric strength is nitrogen under same pressure
2.5 times of gas, breakdown voltage are 25 times of air, and arc extinction performance is 100 times of air, meanwhile, sulfur hexafluoride connecting-disconnecting function is strong,
It can bear higher fracture voltage, it is allowed to continuous open and close times are more, and suitable for frequent operation, noise is small, no fire hazard,
Electromechanical wear is small, thus sulfur hexafluoride breaker in power grid using more and more.With increasing for sulfur hexafluoride equipment, and
Natural aging and damage in equipment running process, maintenance, the service work of equipment also accordingly increase, such as:Sulfur hexafluoride open circuit
Device A is repaiied（Overhaul）, circuit breaker polar is replaced, mechanism case is replaced etc., such work is required for the gas to circuit breaker internal
Replaced.
With reference to current production status, in inflation work of the sulfur hexafluoride breaker after overhaul firstly the need of to equipment into
Row individually vacuumizes, and exhausts that vacuum is later to remove the connector of equipment, then equipment is inflated, and exhausts vacuum and removes and vacuumizes
Connector when due to air pressure, a degree of destruction can be produced to the vacuum inside equipment, it is possible to cause equipment to be filled
The sulphur hexafluoride gas purity entered is unqualified, influences the operational reliability of equipment.
Inflation flow of the sulfur hexafluoride gas-filled equipment after the completion of maintenance is referring to attached drawing 1, the process bag for vacuumizing and inflating
Connecting line is included, vacuumizes, remove six steps such as connector, connection gas-charging connection, connecting line, inflation, operation procedure is cumbersome,
Repeated multiple times dismounting connector adds workload, consumes the time and efforts of staff significantly, influences work efficiency, and
The purity of equipment inner inflatable can be also affected to some extent.Therefore how to improve work efficiency and ensure that equipment is being taken out very
Vacuum in empty and gas replenishment process becomes a problem in operation.
Utility model content
Technical problem to be solved in the utility model is to overcome defect described above, there is provided a kind of simple in structure, use
Sulfur hexafluoride breaker overhaul aerating device that is easy, time saving and energy saving and can guarantee that sulphur hexafluoride gas purity.
In order to solve the problems, such as techniques described above, sulfur hexafluoride breaker overhaul aerating device described in the utility model, bag
Six parts are included, six parts are provided with six interconnected valve ports, wherein being provided with needle valve, a valve at four valve ports
Mouth connection vacuum meter, a valve port are spare.
Further, valve port described in the utility model is arranged on each side two of six parts, each one of front and back end, institute
State a diameter of 12-18 ㎜ of valve port.
The beneficial effects of the utility model：Sulfur hexafluoride breaker overhaul aerating device described in the utility model, structure letter
It is single, production is easily worked, operating procedure simplifies, and time saving and energy saving, equipment is directly inflated after vacuumizing, and is reduced in operation process
In repeated disassembled and assembled connector, the link in gas replenishment process is effectively controlled, is shortened working hours；Due to reducing repeated disassembled and assembled connector
Operation, avoid replace connector when equipment inner vacuum destroyed be subject to atmospheric pressure, it can be ensured that equipment overhaul it is complete after six
Sulfur fluoride Reinheitszahl meets the requirement of relevant regulations more than 99.8%.
Brief description of the drawings
Fig. 1 be prior art breaker overhaul after inflate flow chart；
Fig. 2 is using inflating flow chart after the breaker overhaul of the utility model；
Fig. 3 is the structure diagram of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Sulfur hexafluoride breaker overhaul aerating device described in the utility model, including six parts 1, six parts 1 are set
There are six interconnected valve ports 2, wherein being provided with 3, valve port connection 4, valves of vacuum meter of needle valve at four valve ports
Mouth is spare.
Further, valve port 2 described in the utility model is arranged on each side two of six parts 1, each one of front and back end,
A diameter of 12-18 ㎜ of the valve port 2.
Embodiment：Six parts 1 are fabricated to one of length × width × height=220mm*40mm*40mm with stainless steel material
Six-way valve stent, stainless steel material hardness is high, performance is stable, corrosion resistance is strong, and the left and right sides of six parts 1 opens two directly respectively
Footpath is circular hole, that is, valve port 2 of 15mm, and the valve port 2 of an a diameter of 15mm is respectively opened in the front and back end of six parts 1, in six parts, 1 front end
Valve port 2 at the vacuum meter 4 of 0.1-1Mpa is installed, four 304 stainless steel needle-like of installation in remaining five valve port, are adjusted
J13W-160P, a valve port are spare.
Device checks airtight performance after being completed, and connects and is filled with certain pressure after all pipelines and makes its constant a period of time
Observe whether its pressure value changes, open gas cylinder air pressure to 0.4Mpa after aerating device connecting line, depressurized after three hours
Valve gauge pressure is still 0.4Mpa, it can be seen that the air-tightness of device is good, meets onsite application requirement.
In use, #1 valves leather hose connects sulfur hexafluoride steel cylinder, #2 valves leather hose connection breaker apparatus, #3 valve leather hoses
Vacuum pump is connected, after operation starts, is vacuumized first, #2, #3 valve need to only be opened, remaining valve is closed, and waits to exhaust true
After sky, #3 valves are closed, equipment can be inflated work by opening #1 valves, while vacuum meter 4 can be with breaker
The atmospheric pressure value that density monitor is shown is contrasted.
After onsite application sulfur hexafluoride breaker overhaul aerating device, the inflationtime in each breaker overhaul is reduced,
The final purity test of sulfur hexafluoride breaker meets all more than 99.8% after overhaul《CHINA SOUTHERN POWER Limited Liability wage
Company standard power equipment preventive trial code》Sulphur hexafluoride gas purity should be after overhaul for defined breaker apparatus
More than 99.8% requirement.
