1 Check the appearance of the transformer, see if there is oil leakage in the transformer, or smoke and discharge. Timely discovery and solving problems can avoid the occurrence of fire houses. In addition, it is necessary to check whether the parts are loose. If any accidents are found, the transformers should be disconnected immediately after inspection and maintenance to avoid any hidden dangers;
2Strengthen the measurement of the electric load. During the peak period of power consumption, strengthen the load measurement for each distribution transformer, increase the number of measurements if necessary, and adjust the transformer in time to prevent the neutral current from being too large to blow the lead, resulting in users. The equipment is damaged and the distribution is damaged;
3 Regularly replace the fuse, the fuse selection must be compatible with the transformer capacity;
4 Listen carefully to the sound from the transformer, whether it is the sound produced during normal operation. If not, take appropriate measures in time to find the cause of the problem, solve the problem, and avoid causing greater losses;
5 Regularly check whether the leads are firm. It is necessary to pay special attention to whether the contact at the low-voltage outlet connection is good and the temperature is abnormal.
6 Regularly check the oil temperature and oil color, temperature and climate will cause oil changes, so you need to keep the oil temperature not more than 95 degrees.
