Abstract
The invention relates to a combined type vacuum circuit breaker. Compared with the prior art, the combined type vacuum circuit breaker has the advantages that a high-voltage isolating switch, a grounding switch and a vacuum circuit breaker are fixedly and hermetically integrated by pouring, and are jointly poured in an epoxy-insulation pole unit cavity, and the combined type vacuum circuit breaker is simple in structure and small in size and is environment-friendly.
Description
Affiliated technical field
The present invention relates to the equipment for power transmission and distribution in a kind of high voltage switchgear, belong to electric power system mesohigh power transmission and distribution field, particularly a kind of modular breaker that primary cut-out, isolating switch, earthed switch is sealed into admittedly pole through epoxy resin.
Background technology
In high voltage switchgear power transmission and distribution field; High voltage load switch, high voltage load switch+fuse combined electric apparatus, vacuum circuit-breaker unit are as important turnover line unit, the tranformer protection unit in power transmission and distribution field. and generally; The vacuum circuit-breaker unit can not use separately; Must be used with isolating switch and earthed switch, purpose is that tangible isolation fracture will be arranged, and increases safety of operators; And will make that like this volume requirement of vacuum circuit-breaker unit is very big, thereby increased the space of switchgear house; Because of need are equipped with isolating switch and earthed switch separately, cost also can correspondingly increase in addition.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, volume is less, the insulating protection ability is strong, is convenient to solve the matching of existing combined high-voltage on-load switch.
Technical scheme of the present invention is achieved in that the composite type vacuum circuit-breaker, comprises ground connection fixed contact, moving contact, fixed contact, bus link, epoxy resin, vacuum bubbles, cable termination composition.
Said composite type design is meant that the integral type that has realized high voltage isolator, earthed switch, vacuum circuit-breaker seals cast admittedly, is cast in jointly in the chamber, pole unit of an epoxy insulation, and phase volume is merely 0.06 cubic metre.
Said isolating switch and earthed switch through moving up and down of same moving contact, have been realized combined floodgate, the separating brake action of isolating switch and earthed switch.
The invention has the beneficial effects as follows:
Composite type vacuum circuit breaker constructions of the present invention is simple, volume is little, matching, highly versatile; Realize supporting use with existing combined high-voltage on-load switch of my company and high voltage switchgear thereof, practiced thrift cost greatly.

Embodiment
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.Need to prove before this; Employed term or word can not limited interpretation be common implication or the implication in the dictionary in this specification and claims, and should be based on being interpreted as implication and the notion that meets technological thought of the present invention for the principle that can suitably define the notion of term with its inventor of best mode explanation.Thereupon; The structure of representing in embodiment that this specification is put down in writing and the accompanying drawing is one of most preferred embodiment of the present invention; Can not represent technological thought of the present invention fully, therefore should be understood that to have various equivalents and the variation that to replace for the present invention.
As shown in Figure 1; Composite type vacuum circuit-breaker of the present invention; Be made up of ground connection fixed contact (1), moving contact (2), fixed contact (3), bus link (5), epoxy resin (6), vacuum bubbles (8), cable termination (9), fixed contact (3) comprises moving contact guiding live end (4) and vacuum bubbles conducting end (7).
Said composite type design is meant that the integral type that has realized high voltage isolator, earthed switch, vacuum bubbles (8) seals cast admittedly, is cast in jointly in the chamber, pole unit of an epoxy resin (6) insulation.
Said isolating switch and earthed switch through moving up and down of moving contact (2), have been realized combined floodgate, the separating brake action of isolating switch and earthed switch.When moving contact (2) moves downward with after bus link (5) contacts, isolating switch closes a floodgate, and fixed contact (3) is charged; After moving contact (2) moves upward, separate with bus link (5), this moment the isolating switch separating brake, fixed contact (3) does not have; When moving contact (2) continues to move upward, and with after ground connection fixed contact (1) contacts, fixed contact (3) ground connection, i.e. cable termination (9) ground connection has guaranteed Operation and Maintenance personnel's safety.
Said fixed contact (3) is combined lead live end (4) and vacuum bubbles conducting end (7) of moving contact.
Described composite type vacuum circuit-breaker, combined high-voltage on-load switch and the supporting use of high voltage switchgear thereof that can research and develop voluntarily with my company.
Claims (2)
1. composite type vacuum circuit-breaker; Comprise ground connection fixed contact (1), moving contact (2), fixed contact (3), bus link (5), epoxy resin (6), vacuum bubbles (8), cable termination (9) composition, fixed contact (3) comprises moving contact guiding live end (4) and vacuum bubbles conducting end (7).It is characterized in that: the integral type that has realized high voltage isolator, earthed switch, vacuum circuit-breaker is sealed cast admittedly, is cast in jointly in the chamber, pole unit of an epoxy insulation.
2. composite type vacuum circuit-breaker according to claim 1 is characterized in that: through moving up and down of same moving contact (2), realized combined floodgate, the separating brake action of isolating switch and earthed switch.
