Abstract
The invention relates to an integrated vacuum circuit breaker. Compared with the prior art, the integrated vacuum circuit breaker has the advantages: 1, the integrated design of a high-voltage isolating switch, a grounding switching and a vacuum circuit breaker is realized, and the above devices are sealed an SF6 stainless steel air chamber with the volume being less than 100L; 2, and the simultaneous operation of the isolating switch and the grounding switch is carried out on the same operating spindle, and reaches the interlocking requirement forcibly so as to be safer and more reliable; 3, the integrated design that an operating spindle of a switching-on/off brake and an operating spindle of an isolating grounding switch are operated by vacuum bubbles is realized to save the space greatly; 4, by combining an operating mechanism, when the vacuum circuit breaker is taken as an outgoing-line-side loop, an outgoing line side is grounded after the vacuum bubbles of the vacuum circuit breaker are switched on, thus ensuring the safety of operational maintenance personnel; and 5, the vacuum circuit breaker can be matched with SF6 products in a company and international SF6 products in the same industry for use and a cabinet unit of the vacuum circuit breaker is shortened to be 375mm in width while a cabinet unit of an original vacuum circuit breaker is 750mm-800mm in width, thus decreasing the mounting space greatly.
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.
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, increase safety of operators, and will make that like this volume requirement of vacuum circuit-breaker unit is very big, thereby the space of the switchgear house that increases; 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 existing SF
6The matching of product switchgear.
Technical scheme of the present invention is achieved in that integrated vacuum circuit-breaker, comprise the stainless steel upper shell, go up insulator, vacuum bubbles, stainless steel lower house, down insulator, quiet terminals, isolate moving contact, earthed switch assembly, isolate the ground connection operating axis, main shaft, vacuum bubbles pull bar operating assembly form.
Described integrated design is meant and has realized that high voltage isolator, earthed switch, vacuum bubbles are sealed in SF
6Stainless steel gas is indoor, and volume is less than 100 liters, and spaced apart is 230mm, through the once-forming welding of stainless steel casing, and the integrated function of realization vacuum circuit-breaker unit.
Described isolating switch and earthed switch have realized that the same isolation ground connection operating axis of isolating switch and earthed switch is operated.
Described integrated vacuum circuit-breaker has realized that the main shaft of operation vacuum bubbles on/off switch is isolated the disjunctor design of ground connection operating axis with operation, has saved the space greatly.
Described integrated vacuum circuit-breaker has been realized when vacuum circuit breaker during as the outlet side loop, by with the cooperating of operating mechanism, the outlet side has guaranteed Operation and Maintenance personnel's safety directly by ground connection behind the combined floodgate of vacuum circuit-breaker vacuum bubbles.
Described integrated vacuum circuit-breaker, the supporting use of producer that can already produce the SF6 product with my SF6 of company product and international counterparts, the width of former design breaker cabinet body unit is that 750mm ~ 800mm is wide, narrows down to wide widely for 375mm, has reduced installing space greatly.
The invention has the beneficial effects as follows:
Integrated vacuum circuit breaker constructions of the present invention is simple, volume is little, matching, highly versatile; With the existing SF of my company
6High voltage load switch and high voltage switchgear thereof have been realized supporting use, saved cost greatly, and the switchgear house space that reduces greatly, because isolation, ground connection, vacuum bubbles are by integrated design in the vacuum circuit-breaker unit, five anti-interlocks are apart from more reliable because of shortening.
