Side line outgoing type vacuum post terminal and handcart type side-mounted circuit breaker

Abstract

The invention discloses a side line outgoing type vacuum post terminal which comprises an insulation barrel with a vacuum arc-extinguishing chamber inside, an upper line outgoing conductor and a lower line outgoing conductor. The upper line outgoing conductor and the lower line outgoing conductor are electrically connected with the vacuum arc-extinguishing chamber respectively. The upper line outgoing conductor is arranged in the axial direction of the insulation barrel. The lower line outgoing conductor comprises an inclined section and a vertical section, wherein the inclined section keeps an included angle with the axial direction of the insulation barrel, and the vertical section is parallel to the axial direction of the insulation barrel. The high-medium pressure side outgoing type vacuum post terminal is simple in overall structure and safe and reliable in operation, the arrangement way of the lower line outgoing conductor is changed, the overall size is smaller so that the side line outgoing type vacuum post terminal can be applicable to a side-mounted circuit breaker, meanwhile, handcart operation can be achieved, and the advantages of the side-mounted circuit breaker are brought into full play.

Description

technical field [0001] The invention relates to the technical field of poles, in particular to a side outlet type vacuum pole and a handcart type side mounted circuit breaker. Background technique [0002] At present, medium and high voltage circuit breakers generally use vacuum poles. Most of the vacuum poles of handcart circuit breakers are formally installed, and side-mounted ones generally adopt fixed installation. Due to insulation problems, side-mounted circuit breakers are difficult to install with handcarts. In this way, it is difficult to take advantage of the miniaturization of side-mounted circuit breakers, and the application is limited. Contents of the invention [0003] The object of the present invention is to provide a side outlet type vacuum pole suitable for medium and high voltages in view of the technical defects in the prior art. [0004] At the same time, the invention also provides a handcart type circuit breaker with a side outlet type vacuum pole....
