Dry type transformer should avoid long-term inverted storage and transportation, and should not be subject to strong impact; avoid rain, moisture, high temperature, high temperature or direct sunlight. The distance between the heat dissipation vent and the surrounding objects shall not be less than 40cm; the operation shall be avoided in places with corrosive liquid, gas, dust, conductive fiber or metal chips, as well as in the places with oscillation or electromagnetic interference. The safe operation and service life of dry-type transformer largely depends on the safety and reliability of transformer winding insulation. It is one of the main reasons that the transformer can not work normally when the winding temperature exceeds the insulation withstand temperature. Therefore, it is very important to monitor the operating temperature of the transformer and control the alarm.
The microcomputer maintenance equipment for dry-type transformer is an economical maintenance for measuring, controlling, maintaining and communication integration. It is customized for the high-voltage distribution room at the distribution network terminal, with the three-stage non directional current maintenance as the center, and equipped with the function of monitoring and collecting the grid parameters, which can save the traditional ammeter, voltmeter, power meter, frequency meter, watt hour meter, etc., and can communicate with each other According to the characteristics of distribution network power supply, the equipment integrates the automatic switching function of standby power supply in the equipment, which can sensitively complete the function of incoming line standby power supply and bus distribution standby power supply.
