Hệ thống tạo điện áp xung sét UHV(V) chủ yếu bao gồm Máy phát điện áp xung sét, tủ điều khiển đo xung sét, v.v. Nó được sử dụng để kiểm tra điện áp chịu đựng xung sét toàn sóng, sóng cắt và sóng hoạt động cho GIS, Chất cách điện, Máy biến áp, Bushing, thiết bị đóng cắt HV, cầu dao, công tắc tải, tủ mạng vòng.
It has the features:
1.Adopting PLC technology and using two core optical fibers to transmit control commands and feedback device status, thereby avoiding electromagnetic interference and improving the safety of the control system and computer.
2.The control function has manual, fully automatic, and program control functions, and each level of function is relatively independent to ensure the reliability of the system.
3.Adopting thyristor voltage regulation method and equipped with a charging voltage feedback measurement system.
4.The ignition ball gap and cutoff ball gap distance can be manually and fully automatically adjusted, and displayed on the LCD panel.
5.A cutoff trigger pulse with adjustable time delay and a feedback system with generator ignition trigger.
6.By using a function controlled constant current charging method, the stability of the charging voltage can reach 0.5%.
7.The LCD panel can indicate the charging voltage and charging process of the impact generator, with an accuracy of 1%.
8.The charging voltage and time can be directly input from the LCD panel.
9.Equipped with abnormal charging protection function, capable of fully automatic or manual triggering of ignition pulses
10.Indication of the working status of the impact generator, such as spontaneous combustion, not triggered, abnormal charging, stable charging, etc.
11.The grounding and grounding release control of the equipment body and charging part.
12.The charging voltage polarity can be automatically switched through the buttons on the controller
13.Charging process with automatic or manual control of charging voltage
14.Can automatically or manually sound the alarm bell
15.Equipped with automatic protection for overcurrent and overvoltageØ
16.Isolation filter shielding design
