Vacuum switch tube for circuit breaker and manufacturing method of shell of vacuum switch tube
The invention discloses a vacuum switch tube for a circuit breaker and a manufacturing method of a shell thereof, and belongs to the technical field of vacuum switch tubes. The vacuum switch tube for the circuit breaker comprises a shell (1), a moving end assembly and a static end assembly, the shell (1) comprises an outer insulation part (11) and an inner insulation part (12) arranged in the outer insulation part (11), the static end assembly and the moving end assembly are both arranged in the outer insulation part (11), the moving end assembly and the static end assembly are in contact to achieve an electrical access, the moving end assembly and the static end assembly are separated to achieve an electrical open circuit, and the inner insulation part (12) is arranged in the outer insulation part (11). The outer insulation part (11), the inner insulation part (12), the moving end assembly and the static end assembly form a sealing cavity for arc extinguishing, the creepage distance can be increased as much as possible through the arrangement of the inner insulation part (12), the size of the vacuum switch tube can be reduced to a large extent, and the manufacturing cost is further reduced.
一种断路器用真空开关管及其外壳的制作方法，属于真空开关管技术领域。所述断路器用真空开关管包括壳体(1)、动端组件和静端组件，壳体(1)包括外绝缘部(11)和设于外绝缘部(11)内的内绝缘部(12)，静端组件和动端组件均设于外绝缘部(11)内，动端组件和静端组件相接触以实现电学通路，动端组件和静端组件脱离以实现电学开路，外绝缘部(11)、内绝缘部(12)、动端组件和静端组件之间形成可用于灭弧的密封腔室，可以通过内绝缘部(12)的设置，尽可能增加爬电距离的同时，较大程度的减小真空开关管的体积，进而使得制造成本降低。
