Description

A kind of high pressure sulfur hexafluoride gas insulated high voltage current transformer
Technical field
The present invention relates to a kind of high pressure sulfur hexafluoride (SF with ultrahigh frequency partial discharge monitoring function 6) gas insulated high voltage current transformer.
Background technology
Write Report on the Work of the Government first from intelligent grid construction in 2010, rise to national strategy, in March, 2011, intelligent grid formally lists country " 12 " development plan in, " intelligent grid " one the concerned degree of word improve constantly.On the pilot work basis of 2009,2010 2 years, China's intelligent grid construction heats up once again.Along with the enforcement of the strong intelligent grid plan of State Grid Corporation of China, transformer station will develop to intelligent substation, and primary equipment will upgrade to intelligent power equipment, and secondary device then becomes intelligent control unit, and this is a revolutionary change.For the product such as transformer, instrument transformer, will make the transition to representing intelligentized self-diagnostic function.At present, China's high pressure SF 6the intellectuality transition of gas insulated high voltage current transformer or blank.At high pressure SF 6gas insulated high voltage current transformer erecting bed, due to limited conditions, generally all cannot carry out the test of product partial discharge quantity, therefore affect to the safe and reliable operation of product and network system.
Summary of the invention
The object of this invention is to provide a kind of high pressure sulfur hexafluoride gas insulated high voltage current transformer with ultrahigh frequency partial discharge monitoring function, can meet on-the-spot high pressure SF 6the on-line testing of gas insulated high voltage current transformer partial discharge quantity needs.
A kind of high pressure sulfur hexafluoride gas insulated high voltage current transformer with ultrahigh frequency partial discharge monitoring function, comprise the base, insulator, support insulators and the secondary coil radome that connect successively, in this insulator, secondary line shielded-plate tube is also installed, its special feature is: on described secondary coil radome, be provided with ultrahigh frequency partial discharge transducer, the output of this ultrahigh frequency partial discharge transducer is connected to the binding post be arranged on base by cable, thus as output.
Its middle connecting terminal adopts radio frequency connector.
Wherein cable passes from secondary line shielded-plate tube.
Ultrahigh frequency partial discharge transducer installed by current transformer of the present invention, has solved on-the-spot high pressure SF 6the on-line testing problem of gas insulated high voltage current transformer partial discharge quantity, provides technical support for system mode analysis and aid decision simultaneously, makes electrical network possess self-diagnostic function.Carry out on-line monitoring by Systematical control simultaneously, original traditional high pressure SF6 gas insulated high voltage current transformer is made the transition as the "smart" products with self-diagnostic function.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of high pressure sulfur hexafluoride gas insulated high voltage current transformer with ultrahigh frequency partial discharge monitoring function, comprise the base 6, insulator, support insulators 4 and the secondary coil radome 1 that connect successively, in this insulator, secondary line shielded-plate tube 5 is also installed, improvements of the present invention are mainly, secondary coil radome 1 is provided with ultrahigh frequency partial discharge transducer 2, the output of this ultrahigh frequency partial discharge transducer 2 is connected to the binding post 7 be arranged on base 6 by cable 3, thus as output.
As shown in Figure 1, its middle connecting terminal 7 adopts radio frequency connector, and cable 3 passes from secondary line shielded-plate tube 5.
