Description
Technical field
The present invention relates to a kind of high pressure sulfur hexafluoride (SF that monitoring function is put in hyperfrequency office that has
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 is formally listed country " 12 " development plan in, and the attention rate that receives of " intelligent grid " speech improves constantly.On the pilot work basis in 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 variation.For products such as transformer, instrument transformers, will make the transition to the intelligentized self-diagnostic function of representative.At present, China's high pressure SF
6The intellectuality of gas insulated high voltage current transformer is still blank transition.At high pressure SF
6The gas insulated high voltage current transformer erecting bed because condition is limit, generally all can't be carried out the test of product partial discharge quantity, and therefore the safe and reliable operation to product and network system affects.
Summary of the invention
The purpose of this invention is to provide a kind of high pressure sulfur hexafluoride gas insulated high voltage current transformer that monitoring function is put in hyperfrequency office that has, can satisfy on-the-spot high pressure SF
6The on-line testing of gas insulated high voltage current transformer partial discharge quantity needs.
A kind of have a high pressure sulfur hexafluoride gas insulated high voltage current transformer that monitoring function is put in hyperfrequency office; Comprise the base, insulator, support insulators and the secondary coil radome that connect successively; The secondary line shielded-plate tube also is installed in this insulator; Its special feature is: on said secondary coil radome, hyperfrequency office is installed and puts transducer, the output that transducer is put in this hyperfrequency office is connected to the binding post that is installed on the base through cable, thereby as output.
Its middle connecting terminal adopts radio frequency connector.
Wherein cable passes from the secondary line shielded-plate tube.
Hyperfrequency office has been installed on current transformer of the present invention has put transducer, solved on-the-spot high pressure SF
6The on-line testing problem of gas insulated high voltage current transformer partial discharge quantity simultaneously for system mode analysis and aid decision provide technical support, makes electrical network possess self-diagnostic function.Can carry out on-line monitoring through system's control simultaneously, original traditional high pressure SF6 gas insulated high voltage current transformer is made the transition to having the "smart" products of self-diagnostic function.
