In modern society, whether in industry, agriculture, transportation, defense, culture, education and health, finance, commerce, tourism and other services, and people's lives are inseparable from power. Electricity generation, transportation, use, Harbin high voltage vacuum circuit breakers, power distribution is an extremely important part. Distribution system including transformers and a variety of high and low voltage electrical equipment, Jilin high-voltage vacuum circuit breakers, low-voltage circuit breaker is widely used as a surface using large appliances. Welcome to inquire buy! As we all know, because of the vacuum breaker closure will cause closure of over-voltage, especially when negative emotional breaking small cut such as motors, under normal circumstances, to limit the over-voltage and over-voltage to the vacuum circuit breaker with absorbing devices such as SicRC Road, ZnO arrester, which makes large-scale structure and the complexity of the circuit breaker Dalian high-voltage vacuum circuit breakers, and some over-voltage limit is not ideal. Fourth, the main advantage EA9R leakage protection circuit breakers, for a pre-assembled earth leakage circuit breaker (earth leakage circuit breaker + attachments), is the maximum to avoid the risk of misuse assembled drain attachment. Can also provide overload, short circuit, leakage protection. In the event of leakage protection device operation, the device has a red front mechanical indication distinguishing leakage failure and other protection. Dalian high-voltage vacuum circuit breakers, Huayi Electric Power (certified), high-voltage vacuum circuit breaker is provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future.
