35kv voltage instrument transformer

Description

The voltage transformer of the type JDJ(J)2-35 is single phase and oil-filled product. It is used for metering electric energy, voltage control and relay protection in the electric system up to rated frequency 50Hz or 60Hz and rated voltage 35kV.

This voltage transformer has three poles and the iron core is made of sheet. The body is fixed on the box cover by clamping. There have the primary nd secondary busing also on the box cover.

Overall Dimension

ollowing three-phase five-pole type voltage transformer, this model voltage transformer is one new type anti-ferromagnetic resonance volt transformer developed for preventing transformer's burn danger because of ferromagnetic resonance resulted from different- degree earthing of power system, this product can run normally for long-term and drive protective winding produce 10Ov volt for starting relay even if 100% earthing fault taken place for system. This product could supply standard volt to voltage meter’ power and wait -hour meter, besides, it also can supply volt to earthing relay and earthing leak hunting device, so as to realize earthing alarm and leak-hunting function, consequently, it will replace earthing voltage transformer composed of JSJW and JDZJ model product. This model volt transformer is applied to indoor device's power system of AC frequency 50Hz, rated volt being 10kv or lower, to be used for volt and electric energy measuring as well as relay protection.
