Circuit breaker is an abbreviation for pole type circuit breaker. Circuit breakers are also vacuum circuit breakers, and compared to ordinary vacuum circuit breakers, the only difference is the packaging material. However, when it comes to deeper technical issues, circuit breakers have significant differences from ordinary vacuum circuit breakers.
Circuit breakers are encapsulated by pouring epoxy resin outside the original vacuum bubble. Compared with traditional assembled poles, pole poles have significantly reduced parts, simpler structure, and easier installation, simplifying the manufacturing process of circuit breakers and greatly improving their reliability and stability.
Due to the vacuum arc extinguishing chamber being embedded in epoxy resin insulation material, it transforms the original surface insulation into volume insulation, so no further treatment is required. The fixed sealing pole can achieve high insulation strength, which is more conducive to the miniaturization design of circuit breakers and switchgear.
The vacuum arc extinguishing chamber and related conductive components are simultaneously embedded in epoxy resin solid insulation material, shielding it from external environmental influences. It is completely maintenance free during the product's service life, making it highly adaptable and widely applicable in various fields such as chemical, metallurgical, mining, etc.
Although its production cost is relatively high, the main circuit that encapsulates the low resistance vacuum arc extinguishing chamber and outlet socket in epoxy resin improves the insulation level and anti pollution ability, eliminating the influence of condensation.
