Technical field
This utility model relates to one for oil-gas type transformator and GIS (Gas Insulated Substation gas
Insulated full-enclosed combined electrical apparatus) connect air chamber cover plate assay device, belong to transformer high-voltage test field.
Background technology
In power system, a kind of oil-gas type transformator (transformer bank combined electric appliance represents with T-GIS) is
Gradually popularization and application, owing to this oil-gas type transformator is different from traditional power transformer high-voltage terminal mode and structure, foundation
Country GB50150 2006 " Erection works of electrical installations Standard for handover test of electric equipment " and industry standard Q/GDW1168
2013 " power transmission and transformation equipment state overhauling testing regulationss " can not use Traditional Method to enter when carrying out oil-gas type electrical test of transformer
Row test, because oil-gas type transformer high-voltage three-phase sleeve pipe is directly by GIS (the Gas Insulated being attached thereto
The gas-insulating and fully-enclosed combined electrical apparatus of Substation) and cable output.
So-called Traditional Method, it is simply that before carrying out power transformer high voltage electrical test, it is necessary to tested transformator is had a power failure, then
Being disconnected by terminal head on all high and low lead-out wires (by sleeve pipe, GIS or cable), the method can to conventional electric power transformator
OK, the most not all right for oil-gas type transformator (T-GIS).If it is desired to operating oil-gas type transformator is tested, it is necessary to
Get rid of oil-gas type transformator to be connected between GIS (the gas-insulating and fully-enclosed combined electrical apparatus of Gas Insulated Substation)
SF6 gas in air chamber, removes the cover plate connected on air chamber, is removing oil-gas casing and GIS (Gas Insulated
The gas-insulating and fully-enclosed combined electrical apparatus of Substation) between union joint can carry out.New equipment handing-over carries out various test
Time the most abundant, but operating transformator is carried out high voltage electrical test, the time just seems the shortest (general power system
Power off time is less than 12 hours), if getting rid of the gas connected in air chamber, wait the high-potting item that oil-gas type transformator is carried out
Mesh is the most complete, reconnection, then puts 24 hours (GB50150 2006 electric device peaces by quiet for gassy in connection air chamber
Dress engineering electrical equipment the 20.0.5 article SF6 gas of commissioning test standard can be tested after being filled with electrical equipment 24h) enter
Row gas test, qualified after can run, this method time length, efficiency are low, and affect power supply reliability.
In order to ensure power supply reliability, shorten connection air chamber after having a power failure and discharge SF6 gas, fill SF6 gas and oil-gas type transformation
The time of device body test, (Gas Insulated Substation gas is exhausted for utility model one oil-gas type transformator and GIS
Edge fully closed combined electric unit) the connection air chamber cover plate assay device that connects, it is possible to solve an above-mentioned difficult problem easily.
Explanation of nouns:
Oil-gas type transformator: so-called oil-gas type transformator, also referred to as transformer bank combined electric appliance (use T-GIS table
Show), refer to that transformer high-voltage lead-out wire is not drawn by condenser-type terminal, but direct and GIS (Gas Insulated
The gas-insulating and fully-enclosed combined electrical apparatus of Substation) connect, and by GIS (Gas Insulated Substation gas
Insulated full-enclosed combined electrical apparatus) inner cable leads on transmission tower.
Connect air chamber: what is called connects air chamber, i.e. oil-gas type transformator and GIS (Gas Insulated Substation gas
Body insulated full-enclosed combined electrical apparatus) between an independent air chamber connecting, plenum interior removably connects oil-gas type transformator
ABC three-phase major loop conducting rod with GIS (the gas-insulating and fully-enclosed combined electrical apparatus of Gas Insulated Substation).As
When fruit needs to carry out oil-gas type transformator delivery test or on-the-spot check detection test, then need to remove this air chamber,
After oil-gas type transformer high-voltage outgoing position installs the special assay device with trocar sheath, just can be according to national standard
The high-potting project of GB50150 2006 " Erection works of electrical installations Standard for handover test of electric equipment " and method are to oil gas
Formula transformator carries out an acceptance inspection test；If need oil-gas type transformator is carried out periodic detection test, then need to get rid of this gas
The SF6 gas of chamber interior, then opens cover plate, removes ABC three-phase major loop conducting rod, then draws hole by cover plate, according to industry
Oil-gas type is become by high-potting project and the method for standard Q/GDW1168 2013 " power transmission and transformation equipment state overhauling testing regulations "
Depressor carries out routine test.
