Abstract
The utility model relates to a vacuum circuit breaker on an outdoor lamppost, comprising upper insulating cylinders, lower insulating cylinders, vacuum arc-extinguishing chambers, operation transmission mechanisms, and a box. The vacuum arc-extinguishing chambers are disposed in the upper insulating cylinders. The operation transmission mechanisms are fixed in the box. Breaker contacts are disposed in the vacuum arc-extinguishing chambers. Incoming line contacts are disposed on upper end faces of the upper insulating cylinders, and outgoing line contacts are disposed on side walls of the lower insulating cylinders. The upper insulating cylinders and the lower insulating cylinders are connected in a totally closed manner. The lower insulating cylinders are fixed on the box to form a three-phase column type structure. The vacuum circuit breaker on the outdoor lamppost is advantaged by stable on-off performance and high insulation class, and is suitable to be used in a 24KV/50Hz three-phase current electrical power system.
