Operation of oil immersed transformer

The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date,BalmazuvarosWarranty period of oil immersed transformer, sampling person, weather conditions and other materials of the oil sample.

Balmazuvaros.How to maintain dry-type transformer?

The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.

The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.

For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.

The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However for the general application environment, the class H dry-type transformer can be used.

What about oil immersed transformer fire?

middleman.After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.

If the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.

The raw materials of Fushi blue can be used for bonding so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
