Busbar PT protection measuring control device mainly used for 35KV、10KV、6KV such Protection and control of voltage level of single Busbarr PT cabinet, The protection device is provided with such Perfect protection function of Busbar over voltage、Busbar low voltage、Busbar PT line-break， Busbar PT no-voltage 、Busbar Insulation monitoring, Widely used in 35KV, 10KV, 6KV voltage level user engineering. If you need 35KV voltage level of the Busbar PT protection device, you can use our 965 Busbar PT measurement and control device
protection function:
01 Busbar overvoltage (alarm);
02. Busbar low voltage （Alarm);
03. Busbar PT line-break （Alarm);
04. Busbar PT no-voltage （Alarm);
05. Busbar Insulation monitoring（Alarm);
Description: under the conditions, the protection function can be increased to meet the needs of the field.
remote control function:
Busbar voltage：UA1、UB1、UC1、U01、UAB1、UBC1、UCA1；
Control function:
Separation of the knife gate.
Auxiliary function:
01. Operation instruction：When the device is running normally, "ok" indicator light has a regular flashing;
02. Power instruction:When the device is operating normally, the "power" indicator light is always on;
03. Abnormal device：checksum error-default, blocking relay out;
04 Device alarm:The voltage reaches the set initial value and remains to the set time;
05 Device trip: no;
06 close or break instruction: sub - joint instruction of the isolation knife gate;
07. Event record:Can 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.
Protective action principle
Over voltage, low voltage、PT Break、PT no-voltage 、Busbar insulation monitoring principle is the same as 9541 Busbar PT protection measurement and control device
