Factors Affecting Partial Discharge of Transformer in Electroslag Furnace

With the rapid development of my country's national economy, the demand for electric power is also increasing day by day. As the main equipment in the power transmission and transformation system, the transformer has also developed by leaps and bounds. In order to adapt and meet the market demand, many manufacturers are constantly improving their products Structure, improve product function, introduce advanced production technology and equipment from abroad, and make unremitting efforts in the exploration of new technology and new materials.

Many manufacturers do not pay attention to the processing of insulating parts, and the environment of the insulation workshop is not good. In this way, it is difficult to ensure the insulation strength of the coil. Even some small enterprises share the same equipment for the processing of insulating parts and metal parts. It should be constant temperature and humidity. .Insulation cardboard chooses high-density cardboard, otherwise it must be densified. Most manufacturers can do this. In this way, the functions of insulation, heat dissipation and mechanical force resistance can be ensured. , Chamfering treatment. Conditions should increase insulation machining center equipment.

The welding of lead wires is now commonly used flame brazing, or resistance brazing of copper welding machines, and some large enterprises use cold welding. Pressure welding, most of the foreign countries use cold pressure welding or high-frequency brazing, and now high-frequency brazing is still blank in China. The lead length must be moderate, that is, not too tight to cause vibration and stress, and not too long to avoid Vibration, short circuit discharge.

There are many factors that affect the partial discharge, but the cleanliness of the body is a very important link. Only by drying with kerosene vapor can the body be completely washed clean during the drying process, and the drying effect is very good. The fully automatic vapor phase drying equipment developed by the company is the most advanced equipment in China that can guarantee the function.
