Description
Technical Field
[0001] The invention relates to the technical field of transformers, in particular to an anti-waterlogging transformer which is easy to maintain. Background Art
[0002] The transformer converts AC power of one voltage level into AC power of another voltage level of the same frequency through electromagnetic induction between coils and using the law of electromagnetic induction. When the primary coil of the transformer is connected to an AC power source, an alternating magnetic flux is generated in the iron core. This alternating magnetic flux passes through the primary coil and the secondary coil at the same time, and due to the effect of electromagnetic induction, an induced electromotive force is generated in the secondary coil. By changing the turns ratio of the primary and secondary coils, the voltage can be increased or decreased.
[0003] There are various types of transformers, which are mainly divided into oil-immersed transformers and dry-type transformers according to the cooling method. The body (coil and core) of the oil-immersed transformer is installed in an oil tank filled with transformer oil. Once a problem occurs with the transformer, maintenance is more troublesome.
[0004] Once a fault occurs in some existing oil-immersed transformers, the transformer oil must be drained from the bottom of the transformer tank, and then the transformer body must be lifted out of the transformer tank for maintenance by external equipment. After maintenance, the transformer body must be lifted back into the transformer tank by external equipment. Not only are the maintenance steps cumbersome, resulting in low maintenance efficiency, but also the need to use external equipment, which increases maintenance capital investment. The wiring terminals of some existing oil-immersed transformers are exposed outside the transformer housing. Since the top of the transformer is flat, on rainy days, sometimes rainwater cannot be drained in time and easily accumulates at the root of the wiring terminals, causing damage to the wiring terminals and leakage, which is extremely unsafe.
