The automatic pressure gel technology(APG) of liquid epoxy resin is a kind of pressure gel technology(PG), which is developed on the basis of vacuum casting technology of epoxy resin. Pressure gel process(PG) is a technology developed by Ciba-Geogy in Switzerland in 1957. In the early seventies, PG technology was further integrated and an automatic pressure gel(APG) technology was developed.
APG technology is suitable for liquid epoxy resin, unsaturated polyester resin, polyurethane resin and organic silicone resin, but in the electrical, electrical and electronic industry, a large number of applications are liquid epoxy resin.Through the cabinet drive mechanism and circuit breaker chassis car to achieve the electrical operation of the "five-prevention" function. Under some new electrical conditions and operation mode, the part of "five-guard" function in the cabinet can not meet the requirements, and the "five-guard" function must be improved.
