The safe operation and service life of baoding dry-type transformer depend on the safe and reliable insulation of transformer winding to a great extent. It is one of the main reasons that the transformer can not work normally that the winding temperature exceeds the insulation tolerance temperature and causes insulation damage. Therefore, it is very important to monitor and alarm the operating temperature of the transformer. The cooling modes of baoding dry transformer are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, the transformer can run continuously for a long time under rated capacity. When forced air cooling, transformer output capacity can be increased by 50%. Suitable for intermittent overload operation or emergency overload operation; Since the load loss and impedance voltage increase are large when overloading, it is in a non-economic operation state, so it should not be in a long-term continuous overloading operation.
Baoding the overload capacity and environmental temperature, the dry type transformer overload before load, dry-type power transformer insulation cooling and heating time constant and so on, if necessary, consult factory for dry a load curve, with the application of dry type transformer, its manufacturing technology is also obtained great progress, predictable, baoding dry type transformer in the future will be in the following several aspects to obtain further development, many areas of development: From mainly distribution transformer, power transformer factory, excitation transformer, metro traction rectifier transformer, the big electric current electric furnace transformer, power plant, Marine and petroleum platform with special transformer and multipurpose development, baoding of dry type transformer used in urban metro and rail transit dry traction transformer, voltage is 10, 20 and 35 kv at three levels, 800, 2500 and 3300 kva capacity, in order to reduce the harmonic pollution, and from 12 pulse rectifier to 24 pulse rectifier.
