Abstract
The utility model relates to a miniaturized vacuum circuit breaker. The utility model is characterized in that an insulating pillar is arranged on the left side of an insulating sleeve; and a current transformer coil is pre-arranged in the insulating sleeve. When in use, an isolating moving contact(1) is arranged on the insulating pillar(7A) which is arranged on the left side of the insulating sleeve(7), and forms an isolating switch with an fixed isolating contact(5) through a contacting knife(4). The main body of the breaker consists of the insulating sleeve(7), a vacuum arc extinguish chamber(6) and a current transformer coil(8). The utility model has the advantages of compact structure, less main loop connectors and small overall size.
Description
Affiliated technical field
The utility model is a kind of vacuum circuit-breaker, belongs to the high-voltage switch gear field, is applicable to outdoor 12KV circuit.
Background technology
At present, the current transformer of known vacuum circuit-breaker is contained in a side of breaker body, is positioned at the outside that is flexible coupling or farther; Installation isolating switch elbow will be mixed special-purpose insulation column and be fixed insulating contact.Such circuit breaker major loop contact is many, and loop resistance is big, and the switch overall structure is loose, and size is big, and spare and accessory parts are many.
Summary of the invention
The utility model is loosely organized at existing circuit breaker, and spare and accessory parts are many, size is big, and problem designs more than the major loop contact etc., and purpose provides a kind of miniaturization, vacuum circuit-breaker easy to assembly, that reliability is high.
The technical scheme that its technical problem that solves the utility model adopts is: make an insulating sleeve, a short insulation column is with in the left side of sleeve, current mutual inductor coil of inside prepackage of sleeve.The moving contact of isolating switch can be directly installed on the insulation column in sleeve left side, forms isolating switch with contact knife and the isolation fixed contact that is contained in the sleeve top; The mutual inductor coil of prepackage can save independently a current transformer and an accessory in the sleeve.
The beneficial effects of the utility model are
1, breaker structure compactness, overall dimensions are little, simple installation.
2, the quantity of spare and accessory parts is few, has improved the reliability of switch.
3, the major loop contact is few, can effectively reduce loop resistance.
