Abstract
A vacuum circuit breaker is provided. With the vacuum circuit breaker adopted, the problem of potential safety hazards caused by incapability of realizing de-energization when a high-voltage circuit breaker is under maintenance can be solved. The vacuum circuit breaker comprises a circuit breaker body; a side portion of the circuit breaker body is provided with a disconnector; an interlocking device is arranged between the circuit breaker body and the disconnector; the disconnector is hinged with an operating handle and a switching-on/switching-off handle respectively; the operating handle is in linkage with the switching-on/switching-off handle through a connecting rod mechanism; the connecting rod mechanism comprises at least one insulating rod; and the switching-on/switching-off handle has a first position formed when switching on is performed and a second position formed when switching-off is performed. According to the vacuum circuit breaker of the utility model, the disconnecting component exists and is arranged at the outer side of the circuit breaker body in a built-in mode, such that the product can reliably switch off a circuit at a wire outgoing end when the product is under maintenance or performs segmented power outage, and therefore, the safety of workers can be ensured; and with the interlocking device adopted, misoperation of the workers can be avoided, and thus, the safety performance of the product can be improved.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker.
Background technology
Along with improving constantly of vacuum circuit-breaker technical merit, vacuum circuit-breaker more and more is widely used in electric power system as the switching device of controlling and distributing electric energy to use, and use department also has higher requirement to vacuum circuit-breaker.Vacuum circuit-breaker because of its arc-extinguishing medium and arc extinguishing after the dielectric in contact gap all be that high vacuum is gained the name; It has advantages of that volume is little, lightweight, be applicable to frequent operation, arc extinguishing need not overhaul, and uses comparatively universal in power distribution network.Primary cut-out will be guaranteed the outage of circuit breaker and leading-out terminal when maintenance or segmentation power failure, can be by the realization of cut-offfing of circuit breaker.But cut-offfing of circuit breaker is internal actions, as insulated connecting rod occurs and damage, and still occurs that certain is mutually charged after circuit breaker is disconnected, and has certain potential safety hazard.Install independently that isolating switch then exists volume excessive, install and troublesome poeration, and can't realize the mechanical anti-misoperation operation interlocking.
Summary of the invention
Can not realize reliable outage for existing primary cut-out in the solution background technology when overhauling, have the problem of certain potential safety hazard, the utility model provides a kind of vacuum circuit-breaker.
The technical solution of the utility model is: a kind of vacuum circuit-breaker, comprise breaker body, described breaker body sidepiece is provided with isolating switch, be provided with interlock between described breaker body and the isolating switch, be hinged with respectively operating grip and deciliter handle on the described isolating switch, described operating grip links by linkage and a deciliter handle, comprise at least one eradication edge connecting rod in the described linkage, the second place the when primary importance when described deciliter handle has connection and disconnection.
As a kind of improvement of the present utility model, described insulated connecting rod is provided with a plurality of external sheds.
As further improvement of the utility model, described external shed is equally spaced on insulated connecting rod.
As further improvement of the utility model, be fixed with connector on the described deciliter handle, described connector is threaded with insulated connecting rod.
As further improvement of the utility model, described operating grip is provided with draw ring.
As further improvement of the utility model, the described insulated connecting rod of described insulated connecting rod adopts the silica gel integrated injection molding.
The beneficial effects of the utility model are, separator is set and separator is built in the breaker body outside, so that the circuit at product reliable disjunction leading-out terminal place of energy when maintenance or segmentation power failure, guaranteed staff's safety, thereby and the setting of interlock avoid staff's misoperation to improve the security performance of product.And the utility model exists simple in structurely, and volume is little, is convenient to the advantages such as the installation of product and maintenance.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure, 1, breaker body; 2, isolating switch; 3, interlock; 4, operating grip; 5, deciliter handle; 6, linkage; 7, insulated connecting rod; 71, external shed; 8, connector; 9, draw ring.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By shown in Figure 1, a kind of vacuum circuit-breaker, comprise breaker body 1, described breaker body 1 sidepiece is provided with isolating switch 2, be provided with interlock 3 between described breaker body 1 and the isolating switch 2, be hinged with respectively operating grip 4 and deciliter handle 5 on the described isolating switch 2, described operating grip 4 links by linkage 6 and deciliter handle 5, comprise at least one eradication edge connecting rod 7 in the described linkage 6, described deciliter handle 5 has the primary importance when being communicated with and the second place when disconnecting (provide among the figure be deciliter handle second place time state diagram).The beneficial effects of the utility model are, separator is set and separator is built in the breaker body outside, so that the circuit at product reliable disjunction leading-out terminal place of energy when maintenance or segmentation power failure, guaranteed staff's safety, thereby and the setting of interlock avoid staff's misoperation to improve the security performance of product.And the utility model exists simple in structurely, and volume is little, is convenient to the advantages such as the installation of product and maintenance.
Described insulated connecting rod 7 is provided with a plurality of external sheds 71, and described external shed 71 is equally spaced on insulated connecting rod 7, and described insulated connecting rod 7 adopts the silica gel integrated injection molding.Such structure can not produce the condensation phenomenon, can prevent from making moist fully, so work in the rugged environment out of doors, the setting of external shed can change the creepage route of outer wall into shaped form by linear pattern, has increased the withstand voltage level of outer wall.
Be fixed with connector 8 on the described deciliter handle 5, described connector 8 is threaded with insulated connecting rod 7.Like this relatively simple for structure, exist connect reliable, the advantages such as easy accessibility.
Described operating grip 4 is provided with draw ring 9.Such structure makes things convenient for staff's operation.
Every technical staff's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
