When it comes to transformers, we all know that it is an important part of high-frequency induction heating equipment. It is connected to the induction coil and used to heat and heat treat the workpiece. But this is just the most basic and simple understanding of transformers. Today, the editor will lead you to have a deeper understanding of transformers.
The anode power transformers of high-frequency induction heating equipment are all step-up transformers. Those with power below 60KW are mostly natural air-cooling type, and those with high power are mostly oil-immersed self-cooling type.
No matter what form of transformer it is, it is beneficial to conduct preventive tests on the anode power transformer regularly according to the transformer operating procedures. For oil-immersed self-cooling types, the dielectric strength of the transformer oil should also be checked. If a major short-circuit accident occurs or a serious spark accident occurs inside the transformer, replacement of the transformer oil should be considered.
For naturally air-cooled transformers, dust on the transformer core and wire packages must be cleaned regularly. Check whether the connecting screws are loose. If the wire package fixing splint or wedge is loose or fallen off, it should be dealt with in time.
Special attention should be paid to the fact that the cooling water pipe of the equipment cannot pass directly over the high-voltage transformer to prevent water pipe leakage from dripping onto the transformer. In summer, it is even more important to prevent condensation water from the water cooling system from flowing to the transformer, causing moisture damage. High-voltage transformers are generally located in the lower part of the machine body and are prone to moisture. For this reason, the workspace of high-frequency induction annealing equipment must be dry, and water cannot accumulate on the ground. Especially when there is water under the machine, it must be wiped off immediately. The condensed water in summer must be well drained and cannot flow arbitrarily.
