It sets.
Background technology
Gas insulated combined electrical equipment (Gas Insulated Switchgear, GIS) is since floor space is small, maintenance work
It is more and more extensive to measure use of the small reason in power grid.It is at present to pay close attention to its state of insulation for GIS more, utilize shelf depreciation
Its state of insulation is detected, a large amount of research has been carried out.
But mechanical body complicated as one GIS, machine performance are also the importance for being related to its safe operation.
There are disconnecting switch, breaker etc., there are the equipment of contact inside GIS, in the junction of contact since connecting rod size becomes
Change, electric current is shunk here, and vibration can be generated at contact, and vibration is transmitted to shell by components such as insulators, is produced in shell
Raw detectable vibration signal.The measurement that GIS machine performances are carried out using vibration signal has been obtained for applying at present.
But at present under study for action in order to simple and convenient, be apply single current signal without applying voltage signal, and
Be in the actual operational process of GIS voltage and current signals and meanwhile act on, therefore study one kind can apply simultaneously voltage and
The experimental provision of current signal is very necessary.
In addition, actual isolation switch contact is mostly used in current research, since the contact condition of practical contact is difficult to
Control, can not carry out careful research, therefore studies and a kind of can characterize the current constriction caused by guide rod is discontinuous
Test parts can then carry out more targeted research.
