The load current of binding post 104,105 measurement, and compare with the parameter setting, then according to comparative result drive output
109th, 110 control 2# high-voltage board closing coil 2FK1 energising, and 2# high-voltage board closes a floodgate, 2# transformer station high-voltage side bus；Now, 2# low pressure inlet wire
The CDK-Y1 intelligent power monitor controller installed on cabinet to low-tension supply phase shortage, under-voltage detection, by input terminal 220,221,
222nd, 223 the signal transmission of 2# on off state, power detecting Y, power detecting H is detected distribution control device to intelligent load,
If abnormity of power supply, 2# transformator carries out fault alarm, if power supply is normal, controls 2# by lead-out terminal 120,121,122
Low voltage incoming line cabinet energy storage, combined floodgate；Exit 1# transformator simultaneously, all loaded by 2# transformator, now, transformer station high-voltage side bus capacity is
The substation capacity of two transformer capacities is 66% about.
When continuing to increase with electric loading, during more than 2# transformer economic operation point, intelligent load detection distribution controls dress
Put lead-out terminal 106,107 and control 1# high-voltage board closing coil 1FK1 energising, 1# high-voltage board closes a floodgate, and 1# transformator adds operation；
Lead-out terminal 106,109 controls network interconnecting circuit tripping operation, 1# transformator and 2# transformator split operation, and now substation capacity is
100%.
When being reduced with electric loading, during less than two transformer economic operation points, intelligent load detection distribution control device
By comparing with the parameter setting, control network interconnecting circuit breaker closing, 1# transformator is out of service, 2# transformator continues fortune
OK, now, transformer station high-voltage side bus capacity is again in 66% about operation of two capacity.
When continuing to reduce with electric loading, during less than 2# transformer economic operation point, intelligent load detection distribution controls dress
Put by comparing with the parameter setting, control 1# transformator to put into operation, 2# transformator is out of service, now substation capacity is again
In 33% about operation, go round and begin again.
This utility model can make 1# transformator and 2# transformator run in the state of economizing on electricity most by such scheme,
Reach distribution transformer loss and reduce 50-60%, effect highly significant.
Above-described is only preferred implementation of the present utility model it is noted that for those skilled in the art
For, under the premise of without departing from this utility model general idea, some changes and improvements can also be made, these also should be considered as
Protection domain of the present utility model.
