1.Outline
PST 645U transformer protection and monitoring device applies to the non-direct grounding
system or low resistance grounding station which voltage level is below 110KV.It can be screened or installed grounding.
1.1Protective function configuration
1) three ctions of the composite voltage lockout over-current protection (III gment can be t to the inver time)
悠然惬意
2) The three ctions of high-pressure side of the zero-quence over-current protection (III gment alarm / trip option)
3) The three ctions the low pressure side of the zero-quence over-current protection (III gment can be t to the inver time)4) overload (alarm / trip option)合欢花花语
5) zero quence overvoltage protection (alarm / trip option)6) Low voltage protection 7) Hand accelerate protection 8) 4-way non-power protection教育孩子的书
1.2 monitoring and controlling functions configuration 1) 22-way external switch input and tele-signal collection;
2) The circuit breaker position, manual switching accident tele-signal collection;3) normal breaker which switching is remote;4) 2 pul input, accumulated electrical;5) time of GPS is adaptive when input.
2Technical parameters
