Product Description

Product Description
JDJJ2-35(38.5) type voltage transformer is an external single-phase three-winding oil-immersed product, suitable for power lines with AC 50Hz, rated voltage 35(38.5)KV, and the neutral point is not directly grounded. Voltage monitoring,  energy metering and power supply for relay protection and signalling devices. This product complies with IEC60044-2 and  GB1207 "Voltage Transformer" standards
The first winding of this type of voltage transformer is used for grounding the neutral point,  so the insulation levels on both sides of the winding are different. The power line side (A side) is completely  insulated, the grounding side (X side) is not completely insulated,  and the A side is insulated by 35 (38.5) The KV porcelain sleeve is drawn out, the X side is drawn out by the 0.5KV porcelain sleeve, and the secondary winding and the residual voltage winding are drawn out by the 0.5KV porcelain sleeve respectively.
This type of voltage transformer can withstand one-phase grounding caused by overvoltage without damage. This type of  voltage transformer must be used in sets of threeJDJJ2-35(38.5) type voltage transformer is an external single-phase three-winding oil-immersed product, suitable for power lines with AC 50Hz, rated voltage 35(38.5)KV, and the neutral point is not directly grounded.

Product features and scope of use
JDJJ2-35 oil-immersed voltage transformer,  the product consists of a fuel tank and a porcelain sleeve installed on it. The bottom of the lower fuel tank is  provided with an oil drain plug,  a grounding bolt and a 4-∮4mm mounting hole . The oil conservator is installed on the top of the high-voltage porcelain  sleeve on the upper part of the product tank,  and the transformer oil conservator is attached with the terminal A of the primary winding (the primary N end is  installed in the secondary junction box). The body fixed in the lower fuel tank consists of an iron core and a coil. The  iron core is made of strip-shaped silicon steel sheets stacked into a three-column type,  the middle core is covered with a coil, and the residual voltage winding,  the secondary winding and the primary winding are wound on the insulating skeleton close to the core in turn,  and the windings are separated by insulating cardboard. , The product is a fully sealed structure,  which can effectively prevent the agingof the insulation.
