YNYDJ series power frequency withstand voltage test device (oil-immersed test transformer) is an improved replacement product of our company on the basis of the original TDM type test transformer.

Compared with traditional test transformers, this series of products have the following characteristics:

1. In terms of edge structure, according to the principle of the "distance effect" of transformer oil, multi-layer insulation is adopted to divide the internal insulation of the transformer into multiple oil passages, thereby improving the degree of insulation and reducing the volume.

2. Solve the oil leakage problem of TDM series transformers. Since TDM series transformers have no oil reservoir, when the temperature is too high, the oil will leak out from the oil nozzle after expansion, and this series of products will install the oil injection hole in the bushing At the top, the oil in the casing is communicated with the oil in the body. Therefore, the casing has a silicon stack in addition to it. In addition to the functions of short-circuit bar and series excitation bar, it is also equivalent to a transformer oil reservoir.

3. This series of products adopts metal fixed lead wires and equalizing voltage to eliminate the discharge phenomenon.

4. The stain box is compact in structure, novel in appearance and small in size. Lightweight.

5. The iron core is a single frame core type, using DQ type, 0.30mm cold-rolled oriented silicon steel sheets laminated, and fastened with new special materials, replacing the traditional core-through screw. The coil is a concentric cylinder. Multi-layer tower structure.
