Product Description

  ZY-PDM1000U-C high frequency partial discharge, partial discharge / temperature / circulation online monitoring system
  ZY-PDM1000U-C UHF partial discharge on-line monitoring system consists of sensors, digital processing acquisition and communication unit, and background analysis software. It can realize on-line monitoring of partial discharge, temperature, and vibration of three-core cables. On-line monitoring of discharge, circulation, temperature, and vibration. The system can use CT to take power on the high-voltage side of the cable or directly connect to 220V.
  The system can monitor the circulating current of the metal sheath of the cable, the current of the accidental return line, the high-frequency current signals generated by the partial discharge, the cable surface and joint temperature, the vibration of the intermediate and terminal joints, and realize line monitoring, so as to realize the early warning of the slow aging of the outer insulation of the cable, Cable outer sheath rapid damage alarm, accident return line theft alarm, connector failure temperature abnormal alarm, connector failure vibration alarm, main insulation high frequency defect manual identification alarm, etc.

Intelligent detection is a major issue for the planning and construction of the ubiquitous electric power Internet of Things system by the State Grid Corporation of China. It is also a key application for solving the problem of interconnection and data sharing of the operation inspection system. It is also an important basis for the practical application of big data analysis for equipment inspection.

A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. It is a key device in the power system. Generally, transformers rarely fail. Once a certain defect occurs inside the transformer equipment, equipment failure is extremely easy to occur. Therefore, strengthening and improving the operation monitoring of transformer equipment is of great significance for ensuring the safe operation of transformers.
