PowerHV-800kV SF6 Resonant system for 550kV GIS Dielectric withstand voltage test

Application

The system is used to do AC voltage test and PD measurement on electric apparatus, speciallyfor GIS combined apparatus, suitable for high voltage lab or site application,especially suitable for locations with limited space such as under-groundsubstations and hydropower stations.

Thesystem could be specially designed for metal enclosed type electric devicessuch as GIS combined apparatus, GIS VT, etc. Also could equipped output bushingfor combined apparatus, insulation products, circuit breakers, isolatingswitches, instrument transformers, capacitors, etc.

Resonance circuit is takenuse of to generate high voltage output.

Features

l Low source power consumptiondue to high quality factor of reactor,

l low PD: metal enclosureisolated interference form outside, the system PD<3pC

l Easy transportation: thetotal height is less than 1.8mwhile transportation. It is able to go across bridges and tunnels.

l No need of connecting cables:since the exciter transformer, variable frequency power supply and reactorcombines to one modular. The connecting cables between are avoided.

l Low noise: using high qualitycore, with special seismic reduction structure, the reactor brings very lownoise less than 60dB in operation.

l Good insulation performance:insulated by SF6, with relatively high safety factor. The system runs reliablyand safe.
