Art, economical synthesis benefit.The whole series of APG technologies are introduced from abroad in the later stage 1980s, electrician's industry in China
Equipment, formula and mating chemical materials make China's epoxy resin integral insulation structural quality greatly increase a step.
But current APG technologies application is mainly also limited to the production of electrical apparatus insulation component, and become when being used for dry type
Also many problems demands solve when the technique of depressor and mutual inductor manufactures, due to transformer, mutual inductor first and second coil,
Iron core etc. is all enclosed in epoxy resin, so having higher insulation and performance requirement, although domestic many producers through attacking for many years
It closes, but the product that can produce the whole technical conditions of really satisfaction is also very rare so far.This is because pouring into a mould mutual inductance using APG
When the large products such as device, since APG is easy solidification in the case of a high temperature, the material solidification in die cavity center is just relatively slow, when relatively outer
After part and sprue channel open are cured, inside just slowly cures, and epoxy resin will produce volume contraction when solidification, and at this time because of running channel
It is cured, supplement material can not press-in die again, therefore easily generate cavity because shrinking in inside, and this part is exactly often mutual inductance
The major insulation region of device primary coil and secondary coil, causes dielectric strength to reduce, and Characteristics of Partial Discharge is deteriorated.So when cast
It is required that mixture is just rapidly heated before entering mold, but according to the characteristic of epoxy resin, under high temperature it can rapid curing, institute
Higher material temperature should be kept it cannot to be allowed to be solidificated in pipeline again, just at an awkward thing.
