What are the unique features of the encapsulated transformer?

The potting transformer has the function of temperature setting, supports manual/automatic fan startup and shutdown, and has the functions of sending out fault, overtemperature audible and visual signal alarm, overtemperature automatic trip, etc. Of course, the features of the potting transformer are more than that. The following section will give you a detailed introduction. Let’s continue to look:

1. It has good performance and low partial discharge value. Due to its unique structure and advanced manufacturing technology, the encapsulated transformer has low partial discharge value.

2. It has strong lightning impulse resistance. Because the high and low voltage windings are all wound with copper tape (foil), the interlayer voltage is low, the capacitance is large, and the initial voltage distribution of the foil winding is close to linear, it has strong lightning impulse resistance.

3. It has strong short circuit resistance. Because the high and low voltage windings have the same reactance height without spiral angle, the ampere turns between coils are balanced, and the axial force caused by short circuit of high and low voltage windings is almost zero, it has strong short circuit resistance.

4. The anti cracking performance is good. The encapsulated transformer uses epoxy resin “thin insulation technology”, which meets the requirements of low temperature, high temperature and large temperature range, meets the anti cracking requirements after long-term operation, solves the cracking problem that is difficult to solve with “thick insulation technology”, and makes the encapsulated transformer technically reliable.

5.The encapsulation protection level of the encapsulated transformer is relatively high, that is, dust-proof and waterproof. Epoxy resin has good bonding strength and dielectric properties with metal and non-metallic materials.

The cured epoxy resin has small shrinkage, good dimensional stability, high hardness and good flexibility. After the transformer is filled with glue, the product has the functions of impact resistance, insulation, fixation and noise reduction; After the transformer is tested and sealed, the stability of the transformer is good, and other changes are not easy to occur, and the working conditions are not easy to change.
