Transformers is a core part of power systems and industrial processes, in general, the work environment of transformer is harsh.Transformer's  malfunction effect  reliability of electricity supply chain, and may hurt the personal safety of users.Therefore,it's necessary to monitor the operating condition and performance of transformers in order to avoid or reduce disruption due to sudden unexpected failure.Zhejiang Xiecheng Electric Co.,Ltd  develop Remote Monitoring System for Transformer's operation condition.It also helps to save running costs by optimizing maintenance schedules.

• Schematic of System Application

• Brief Introduction of System Application Schematic

  1.Inputting the switching value and analog quantity of transformer and cooler to the detecting system, and also connect to high voltage switch cabinet microprocessor protection device.

   

  2.Every once in a while( customized ),  the system will send the running condition of transformer and cooler as a message to the administrator ( can set 5 persons). And The administrator also can edit message “CX”  send to the system while the system will report the condition of transformer and cooler soon.

   

  3.When the transformer and cooler abnormality running, the system will send the message to every administrator mobile phone within 5 seconds as soon as detected, and also will calling to the first administrator at first time. Meanwhile The switching value of abnormality will output to high voltage switch cabinet microprocessor protection device

• Test item of Operation condition as below：

  1.Switch value：

  a.Transformer high temperature alarm.

  b.Transformer super-high temperature trip.

  c.Transformer light gas trip.

  d.Transformer heave gas trip.

  e.Transformer high oil level alarm

  f.Transformer lower oil level alarm.

  g.Transformer pressure relief valve motion alarm

  h.Cooler oil flow failure alarm.

  i.Cooler water pressure decompression alarm

  j.Cooler water pressure over-pressure alarm.

   

  2.Analog quantity(digital display)

  a.Transformer load current value

  b.Transformer oil level temperature measured value.

  c.Customrized analog input according with the user requirement.

• The advantage of system：

  1.The Transformer detected by the system can let us know the problem immediately, and solve the problem soon.

  2.The system also can send the running condition of transformer to our after-service Monitor computer database, Let Xiecheng transformer and user together monitoring and managing the transformer.
