Product Description

JDJ2-35(38.5) Model outdoor Oil-Immersed Voltage Transformer

Product Description

General Summary:
JDJ2-35(38.5) model Potential Transformer is one-phase double-winding,oil-impregnated type outside product, suitable to be used at A.C.50Hz power line with rated voltage 35(38.5)KV for voltage & energy measuring and relay protection of associated equipments.

This model potential Transformer is suitable for power line of single-phase and three-phase. When it is used in three-phase power line, two potential transformers can be connected to be "V" line, see wiring drawing1&2.

JDJJ2-35(38.5) model potential transformer is an outside type single-phase three winding oil-impregnated product, applicable to be used at A.C.50Hz power line with rated voltage 35(38.5)KV which neutral point non-directly earthing for voltage & energy measuring and relay protection and power-supply of signal device.

First winding of This model potential transformer is used for neutral point earthing, so insulation level of two side of winding is different, power line side(A side) is completely insulated, and earthind side(X side) is imcompletely insulated, A side is fetched out by 35(38.5)KV porcelain sleeve, X side is fetched out by 0.5KV porcelain sleeve, second winding and residual voltage winding is fetched out by 0.5KV porcelain sleeve respectively.

This model potential transformer can withstand over-voltage caused one phase earthing without damage. This model potential transformer must be used at three whole set ,see its winding wiring diagram 3.


Structure Brief Introduction:
JDJ2-35 model potential transformer is made of silicon-steel piece type fold three-core pole type for its iron core. Second winding and first winding at middle pole. Second winding wind in insulation canister, first winding sub-sect symmetrically, wind in another insulation canister, two side of winding has static ring, outer-surface of head & end has static shield. Two winding is multi-layer cylinder type, first winding covers second winding, there's oil path between windings.
Machine is fastened at the oil-box cover by nip tool, box cover is equipped with oiling stuff and oil tank. Top of oil tank has breathing-hole stuff, bottom is equipped with oil stuff, its side is equipped with panel oil-meter, oil tank's cliff is equipped with earthing bolt and oiling stuff, box bottom is welded with bracket which has four installation hole.
