GIS VT Supporting Products (JDQXFH)

Product overview

JD (S) QXFH products have two structural modes of three-phase common box and three-phase separate box. Usually, the basin and air valve are specified by GIS manufacturers or directly provided as customer parts, and the other sizes are designed by VT manufacturers themselves if they meet customer installation requirements.

◎ This type of transformer and GIS combined electrical appliances are used together, and are widely used in power systems with nominal system voltage of 66-1000kV and frequency of 50/60Hz, providing voltage signals for secondary measuring instruments, protection and control devices.

◎ Aluminum alloy shell, stainless steel nameplate and other components, long-term outdoor operation without corrosion.

◎ The dust-proof, waterproof and breathable sealing structure of the secondary outlet box meets the requirements of IP55. The secondary terminals for user wiring are Phoenix special terminal terminals, which makes the operation of inserting, pulling and wiring more convenient and fast.

◎ The product is suitable for areas with high and low temperature changes and harsh ambient temperature, and the annual leakage rate is less than 0.5%.

◎ The high voltage coil is wound with imported ringer glued polyester film and imported enamelled wire, with high insulation strength and stable performance

◎ The overall design is reasonable, it is capacitive under a certain voltage, and it is not easy to have ferromagnetic resonance.
