Circuit breaker having an encapsulated auxiliary coil assembly |
摘要 |
A circuit breaker which has an auxiliary coil fitted onto the primary bobbin adjacent the pole piece having a dielectric auxiliary bobbin and a dielectric bobbin housing encapsulating the auxiliary coil and forming an encapsulated auxiliary coil assembly. Both the dielectric auxiliary bobbin and the dielectric bobbin housing are comprised of a polymeric material, preferably a liquid-crystal polymer. Preferably, the liquid-crystal polymer is an aromatic liquid-crystal polyester which is reinforced with about 30% glass and has a nematic liquid-crystal structure. Furthermore, it is preferred for the dielectric strength of the liquid-crystal polymer to be about 32 KV/mm to about 35 KV/mm.
