Description
Technical field
(Gas Insulated Substation gas is exhausted with GIS for oil-gas type transformator to the present invention relates to one
Edge fully closed combined electric unit) connect the cover plate assay device of air chamber and operational approach, belong to transformer high-voltage examination
Test field.
Background technology
In power system, (transformer bank combined electric appliance uses T-GIS to a kind of oil-gas type transformator
Represent) the most gradually popularization and application, due to this oil-gas type transformator and traditional power transformer high-voltage terminal
Mode and structure are different, and according to country GB50150 2006, " electric device installing engineering electrical equipment joins
Test standard " and industry standard Q/GDW1168 2013 " power transmission and transformation equipment state overhauling testing regulations " exist
Traditional Method can not be used when carrying out oil-gas type electrical test of transformer to test, because oil-gas type transformator is high
Directly by the GIS that is attached thereto, (Gas Insulated Substation is gas-insulating and fully-enclosed for pressure three-phase sleeve pipe
Combined electrical apparatus) 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 stopped
Electricity, then disconnects the terminal head on all high and low lead-out wires (by sleeve pipe, GIS or cable), the party
Method is feasible to conventional electric power transformator, the most not all right for oil-gas type transformator (T-GIS).If it is desired to fortune
Oil-gas type transformator in row is tested, it is necessary to get rid of oil-gas type transformator and GIS (Gas Insulated
The gas-insulating and fully-enclosed combined electrical apparatus of Substation) between connect the SF6 gas in air chamber, remove and connect gas
Cover plate on room, removing oil-gas casing, (Gas Insulated Substation is gas-insulating and fully-enclosed with GIS
Combined electrical apparatus) between union joint can carry out.The time that new equipment handing-over carries out various test is the most abundant,
But operating transformator is carried out high voltage electrical test, the time just seem the shortest (general power system have a power failure
Time is less than 12 hours), if getting rid of the gas connected in air chamber, wait the height that oil-gas type transformator is carried out
Pressure pilot project is the most complete, reconnection, then puts 24 hours by quiet for gassy in connection air chamber
(GB50150 2,006 the 20.0.5 article SF6 gas of Erection works of electrical installations Standard for handover test of electric equipment
Body can be tested after being filled with electrical equipment 24h) carry out gas test, qualified after can run, this
Kind 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
The time of gas formula transformer body test, a kind of oil-gas type transformator of invention and GIS (Gas Insulated
The gas-insulating and fully-enclosed combined electrical apparatus of Substation) the connection air chamber cover plate assay device that connects, it is possible to light
Easily solve an above-mentioned difficult problem.
Explanation of nouns:
Oil-gas type transformator: so-called oil-gas type transformator, also referred to as transformer bank combined electric appliance (are used
T-GIS represents), refer to that transformer high-voltage lead-out wire is not drawn by condenser-type terminal, but direct and GIS
(the gas-insulating and fully-enclosed combined electrical apparatus of Gas Insulated Substation) connects, and by GIS (Gas
The gas-insulating and fully-enclosed combined electrical apparatus of Insulated Substation) 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-insulating and fully-enclosed combined electrical apparatus) between connect an independent air chamber, plenum interior removably connects
Oil-gas type transformator and the ABC of GIS (the gas-insulating and fully-enclosed combined electrical apparatus of Gas Insulated Substation)
Three-phase major loop conducting rod.If needing oil-gas type transformator carries out delivery test or on-the-spot check inspection
When test is tested, then need to remove this air chamber, install at oil-gas type transformer high-voltage outgoing position special with outward
After the assay device of sleeve pipe, just can be according to standard GB/T 50,150 2006 " electric device installing engineering
Electrical equipment commissioning test standard " high-potting project and method oil-gas type transformator is carried out an acceptance inspection test；
If need oil-gas type transformator is carried out periodic detection test, then need to get rid of the SF6 of this plenum interior
Gas, then opens cover plate, removes ABC three-phase major loop conducting rod, then draws hole by cover plate, according to row
The high-potting project of industry standard Q/GDW1168 2013 " power transmission and transformation equipment state overhauling testing regulations " and
Method carries out routine test to oil-gas type transformator.
