变压器 也得到了长足的发展。 With the rapid development of China's national economy, the demand for electricity is also increasing. As a major equipment in power transmission and transformation systems, transformers have also been developed. In order to meet and meet market demands, many manufacturers have introduced advanced production technology and equipment from abroad in order to continuously improve the product structure and product performance, and have made unremitting efforts in the exploration of new processes and materials. At present, electroslag furnace transformers are mainly developed in two aspects.
Many manufacturers don't pay much attention to the processing of insulation parts. The environment of the insulation workshop is not good. In this way, it is difficult to ensure the insulation strength of the coil. Some small enterprises even share the same equipment for the processing of insulation parts and metal parts. Should be constant temperature and humidity. It is best to use high-density paper for insulation paperboards, or they must be densified. Most manufacturers can do this. This ensures insulation, heat dissipation, and mechanical resistance. The stay cushion must be depilated and chamfered. If conditions permit, you should add insulation processing center equipment.
In the quality accidents of the electroslag furnace transformer, there are many insulation and mechanical accidents caused by lead problems, so pay special attention to lead processing. Welding of the lead wire currently generally uses flame brazing or resistance brazing of a brazing machine. Large-scale enterprises use cold-press welding. At present, most of the foreign countries use cold-press welding or high-frequency brazing. Is blank. The length of the lead must be moderate, that is, it should not be stretched tightly to cause vibration and stress, but not too long to avoid vibration and short-circuit discharge.
There are many factors that affect the amount of partial discharge, but the cleanliness of the body is very important. Only the kerosene vapor phase can be used to thoroughly rinse the body during the drying process. The drying effect is very good and the drying cycle can be shortened. The fully automatic vapor phase drying equipment is a state-of-the-art first-class equipment that can guarantee performance in China.
