The DTBP-II series three-phase combined overvoltage protection device is a new overvoltage protection device for limiting the atmospheric overvoltage and operating overvoltage caused by various vacuum switches. While protecting the phase-ground overvoltage, the phase-to-phase overvoltage can be reduced by 60% to 70%, which is impossible for the traditional lightning arresters. In addition, a protection device can replace multiple arresters, and has become a **** substitute for traditional lightning arresters. The product is suitable for different types of KYN, XGN, GBC, JYN, GZS and other 3~35kV complete switchgears or box-type substation (outdoor products can be used in the open air).
DTBP-II series three-phase combined overvoltage protection device is ideal to protect the transformers, motors, shunt compensation capacitors, busbars, vacuum switches and other electrical equipment in the power system against the atmospheric overvoltage and operating overvoltage, especially the phase-to-phase overvoltage. It is widely used in the electric power, metallurgy, chemical, coal, light industry, construction, electrified railway and other industries.
