Abstract
The utility model discloses a vertical isolating vacuum breaker, comprising a three-station isolating switch, a vacuum breaker matched with the three-station isolating switch, and an operating mechanism, wherein the three-station isolating switch and the vacuum breaker matched therewith are arranged in a manner of three-phase longitudinal arrangement, each upwards-going wire of the vacuum breaker extends to a bottom frame plate to form a hinged joint supporting point and is electrically connected with the bottom end of the disconnecting link of a corresponding isolating switch, and the disconnecting link rotates about the hinge joint supporting point to respectively and conductively contact with an isolating static contact and a grounding contact or to be in a standby state under the control of a linkage main shaft and the operating mechanism. The vertical isolating vacuum breaker is not only provided with the function of a vacuum breaker, but also provided with the function of an isolating switch, and a vacuum arc extinguish chamber is provided with an excellent capability of turning-off a short circuit current, thereby enabling the turning-off capability of the grounding fault of a switch device to be high, thoroughly eliminating the damage caused by electric arc exposure, and enabling the maintenance after the grounding fault to be reduced or omitted, the structure to be simplified, the cost to be reduced, and the dimension of a switch cabinet to be reduced.
Description
Technical field
The utility model discloses a kind of vertical isolated vacuum breaker, divides by International Patent Classification (IPC) (IPC) to belong to electric switch manufacturing technology field, especially relates to a kind of tri-station isolating switch and vacuum circuit-breaker unit switch.
Background technology
Electric switches such as traditional isolating switch, vacuum circuit-breaker and earthed switch all are independently, and in electric power system, require each switch combination to increase the security performance of high-tension apparatus, therefore, occur the unit switch that various switch junctions are integrated on the market.
China document CN 102055142A discloses a kind of novel all-in-one combined electrical apparatus; Comprise tri-station isolating switch; Vacuum circuit-breaker supporting or on-load switch or switch-fuse combination with it, operating mechanism, described tri-station isolating switch switch is arranged on the top of integrated combined electrical apparatus; Other electric elements are enclosed in the epoxy resin seal pole admittedly, are arranged on the below of isolating switch.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of rational in infrastructure, safe and reliable vertical isolated vacuum breaker, can be widely used in all kinds of box-type substations, ring main unit and fixed switch cubicle.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of vertical isolated vacuum breaker; Comprise tri-station isolating switch, vacuum circuit-breaker and the operating mechanism supporting with it; Tri-station isolating switch is that three-phase is vertically arranged with the vacuum circuit-breaker that cooperates; And the last outlet of each phase vacuum circuit-breaker extends on the underframe plate and to form hinged support and electrically connect with the disconnecting link bottom of corresponding isolating switch, disconnecting link under the control of interlock main shaft and operating mechanism around hinged support rotate and respectively with isolate fixed contact, the grounding contact conduction contacts or be the separating brake vacant state.
Further; Described vacuum circuit-breaker is positioned at the above part of underframe plate and is provided with the different umbrella leaf of diameter; Itself and lower part vacuum circuit-breaker are enclosed in the epoxy pole admittedly; Underframe plate rear end links to each other with three isolation mounts through gusset, and outlet row on the three-phase is installed respectively in the insulation tank of three isolation mounts, and outlet row also is connected with insulating contact on each.
Further; Described operating mechanism is arranged at isolated vacuum breaker left side or right side; Comprise the isolating switch mechanism of mechanical through transport and combined floodgate, separating brake and ground connection and the vacuum circuit-breaker that breaker mechanism is respectively applied for the control isolating switch, breaker mechanism adopts plane scroll spring device control vacuum circuit-breaker.
The utility model is the compound integration product of function; The function that not only has vacuum circuit-breaker also has the function of isolating switch, and circuit breaker could close a floodgate when isolating switch and main bus bar (going up outlet row) on-position; Isolating switch ability separating brake behind breaker open operation; The utlity model has following beneficial effect: because vacuum interrupter has the ability that short circuit current was closed and cut-off in good pass, make that the making capability of switchgear earth fault is high, fundamentally got rid of electric arc and exposed the destruction of causing; Realized few (exempting from) maintenance after the earth fault; Realized discrete component compoundization of function, simplify the structure, reduced cost, the more important thing is the size of having dwindled switch cubicle.
