9561 capacitor protection relay

9561 capacitor protection relay

9561Capacitor protection measuring control device mainly used to the voltage levels of high voltage such as 35KV, 10KV, 6KV. The protection device provided the protection for current instantaneous trip, the time limit protection for current instantaneous trip, over current, over current back time limit.(general / very / extreme)、Over load, Zero sequence time delay current instantaneous trip, Zero sequence time delay current instantaneous trip , Zero sequence time delay current instantaneous trip ,Zero-Sequence definite time over-current anti time limit (general / very / extreme), Zero sequence time delay current instantaneous trip , over voltage, low voltage, PT disconnection, PT no-voltage , control circuit disconnection such perfect protection device,widely used in 35KV and the below voltage level ,you can put it to good use to the municipal projects that has no special requirements.

04. Zero sequence time delay  current instantaneous trip :i0(Twice times value);
05. frequency:f;
06. power:P、Q(sampling value*N2);
07.power factor:cos Ф;
 
Control function:
01.the local closing and local tripping of Circuit breaker
02. The remote closing and remote tripping of Circuit breaker
 
Auxiliary function:
01. Operation instruction:When the device is running normally,“run”Indicator light flashes regularly;
02. Power instruction:When the device is running normally,“Power Supply”The indicator light is always on;
03. Abnormal device:checksum error-default,Blocking relay is Open;
04.Device alarm:electric current、Voltage达To set the initial value and keep to the set time;
05. Device trip:Current, voltage Achieve the set trip value and keep it to the set time;
06. Close and brake instructions:the instruction of close or brake ;
07.Event record:Record 32 protection events, 32 remote events, 8 self test events;
08. Online modification:“Protection and retreat”and“Protection fixed value”Modify can be directly modified by computer communications to save;
   09.Online print:Any interface in the protection menu can be printed directly after computer communication;
   10. Communication function:With 485 communication mode.
