Abstract

The invention relates to an outdoor on-post wide-voltage vacuum breaker which is of a three-phase standing post structure. The standing post structure comprises an insulating sleeve, a vacuum arc-extinguishing chamber and an insulating pull rod. The vacuum arc-extinguishing chamber is mounted on the top inner side of the insulating sleeve. One end of the insulating pull rod is connected with the bottom of the vacuum arc-extinguishing chamber while the other end of the insulating pull rod is connected with a drive shaft. An upper cable connector is disposed at the top end of the insulating sleeve. A lower cable connector connected with a mutual inductor is disposed on the lateral side of the insulating sleeve. By the outdoor on-post wide-voltage vacuum breaker, technical requirements of different voltage classes can be met.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breakers, in particular to an outdoor post-mounted wide-voltage vacuum circuit breaker. Background technique [0002] The vacuum switch on the outdoor pole has been developed to this day, and it has become an indispensable electrical equipment for urban and rural power grids, and its market share continues to expand. At present, when many domestic equipment manufacturers design and produce such electrical appliances, they are still traditionally classified into three categories according to the voltage level: 10kV level, 24kV level and 33kV level, which can be described as strict and insurmountable. The upper limit of the rated current of outdoor pole-mounted switches is generally 630A, but it seems to be divided into three levels in terms of voltage, which is very inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to pr...
