Production of dry-type transformers

Dry-type power transformers are widely used in all walks of life in the city has basically replaced the oil-immersed transformers, dry type power transformers in order to ensure safe operation, and do not need special maintenance and management personnel, dry type power transformers need to configure the temperature Tour electri cenergy meter control device (referred temperature controller). However, when the country can  electric meter  transformers, it was not producing  Air circuit breaker  device, rely on imports. Until 1992 domestic production began, then uses a discrete component technology, performance is poor, less functional, low precision, bulky, high failure rate, operation trouble. If using chip technology made ​​into a dry-type transformer intelligent temperature controller.
