This manual introduces the SHK‑TBP three‑phase combination overvoltage protector, describing its unique structure, operating principle, and advantages over conventional surge arresters. It outlines the product’s applications in power, metallurgy, chemical, welding and light‑industry sectors for protecting transformers, switchgear, busbars, motors and other equipment.
Detailed sections cover the device’s external dimensions, mounting methods, electrical parameters, test procedures, preventive maintenance, and the optional over‑voltage action counter modules. Installation safety distances, environmental limits, and recommended periodic discharge tests are also provided. This manual is written in Chinese.
| Operating temperature range | -40°C to +60°C |
|---|---|
| Input voltage | AC210‑AC230V |
| Withstand voltage | AC2000V (1 min) |
| Power consumption | <5 W |
| Weight | <2.0 kg |
The high‑voltage leads must maintain a safe air distance from other equipment as required by safety standards.
A preventive discharge test should be carried out every one to two years.
For a 10 kV system the allowed continuous operating voltage is 12.7 kV.
The device can operate from –40 °C up to +60 °C.
