Description
Technical field
The present invention relates to a kind of device for circuit breaker antiarcing-over, belong to Low Voltage Electrical Apparatus.
Background technology
Circuit breaker is a kind of device for switching that is applied to be used for distributing in distribution network electric energy and protection circuit and power-supply device, when line fault meets circuit breaker and sets protective condition, and circuit breaker disjunction.The disjunction of circuit breaker relies on separately realizing of moving contact and fixed contact, when moving contact and fixed contact separate, can produce electric arc, only has when arc extinction and just can reach real disjunction.Arc extinction mainly relies on arc control device, and under the effect of arc extinguishing grid pieces, electric arc is introduced into arc control device, utilizes proximal pole pressure drop to make arc extinction.Along with the development of electric power system, transformer capacity is increasing, more and more higher to the disjunction requirement of circuit breaker, yet the volume of circuit breaker is but more and more less, and it is more difficult that the limitation in space makes to realize high breaking.Wherein the focus of technology is in striking and heat radiation.
At present, the development trend of circuit breaker is high breaking, miniaturization, without arcing, and, when improving basic mechanical design feature, emphasis improves complex art economic index.As when improving short circuit breaking capacity, answer special concern to reduce flashover distance or realization " without arcing ".In prior art, the device of antiarcing-over generally only has part of protective cover to form.And the different mounting means (wiring after wiring before plate, plate, plug in type connection) of circuit breaker, the area that need to carry out arcing protection is different.Therefore, prior art can not provide reliable arcing protection for the different mounting means of circuit breaker.Because only having part of protective cover, the device of antiarcing-over forms, if the difference for the mounting means of circuit breaker, make different protective covers, can greatly reduce the flexibility that user uses circuit breaker mounting means, also increased production, the cost of transportation of enterprise.
Summary of the invention
In order to overcome above-mentioned the problems of the prior art, the object of the present invention is to provide a kind of device for circuit breaker antiarcing-over, when guaranteeing user for circuit breaker mounting means requirement on flexibility, realize the reliable arcing protection of breaker safe.
To achieve these goals, the present invention is by the following technical solutions:
A device for circuit breaker antiarcing-over, comprises protective cover, wherein: on the protection face of this protective cover, open vertical cut (V. cut); This protective cover with for blocking the sheet arc insulating apparatus of its breach, be flexibly connected, to realize the antiarcing-over effect of the different modes of connection of user.
Grooved guide rail is vertically set on the protection face of described protective cover, and described arc insulating apparatus can slide up and down and be connected with protective cover by inserting this guide rail.
On described protective cover, steam vent is set.
Described arc insulating apparatus is provided with locator protrusions, and this locator protrusions can rest in the steam vent of protective cover.
Described arc insulating apparatus and protective cover clamping.
Draw-in groove or buckle are set on described protective cover; Described arc insulating apparatus correspondingly arranges buckle or draw-in groove; Described arc insulating apparatus and arc insulating apparatus are realized clamping by draw-in groove and buckle structure and are coordinated.
The present invention is owing to having increased the arc insulating apparatus that can be flexibly connected on the basis of protective cover, can according to the variation of circuit breaker mounting means, change arc insulating apparatus relatively and the link position of protective cover at any time, realize the effect that the different mounting means of circuit breaker is provided to reliable protection arcing.

Embodiment
The present invention is for the device of circuit breaker antiarcing-over, comprises protective cover, on the protection face of this protective cover, opens vertical cut (V. cut); This protective cover with for blocking the sheet arc insulating apparatus of its breach, be flexibly connected, to realize the antiarcing-over effect of the different modes of connection of user.
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Case study on implementation 1:
See Fig. 1-Fig. 3, on the protection face of protective cover 1, have three vertical cut (V. cut)s 11, on the protection face of protective cover 1, in each vertical cut (V. cut) 11 both sides, grooved guide rail 12 is vertically set, the arc insulating apparatus 2 of piece shape shape can slide up and down and be connected with protective cover 1 by inserting this guide rail 12.Steam vent 13 is set on protective cover 1.
One end of arc insulating apparatus 2 is provided with locator protrusions 21, and this locator protrusions 21 can rest in the steam vent 13 of protective cover 1.
Wherein the guide rail mating surface 23 of arc insulating apparatus 2 both sides can interiorly at the guide-track groove 11 of protective cover 1 move along O-O axis (perpendicular to paper direction) direction, the locator protrusions 21 of arc insulating apparatus 2 is limited in the steam vent 13 of protective cover 1, make the arc insulating apparatus 2 can be static with respect to protective cover 1 at O-O axis direction, play the effect of circuit breaker antiarcing-over.In the situation that manpower makes arc insulating apparatus 2 in E-E direction generation strain, the restriction protrusion 21 of arc insulating apparatus 1 deviates to enter another one steam vent in the steam vent 13 of protective cover 1, realizes the variation of two stop places.The variation of these two stop places has adapted to front wiring (seeing Fig. 4) the preventing arc needs different with back connection of circuit breaker (seeing Fig. 5) of breaker plate.In figure, 3 is circuit breaker internal wiring plate, and 4 is external terminal board or binding post.
Case study on implementation 2:
Fig. 6 and Fig. 7 have shown a kind of position relationship schematic diagram of the device for circuit breaker antiarcing-over, and it comprises protective cover 1 and arc insulating apparatus 2.Wherein on the back side of arc insulating apparatus 2, there is buckle 23, on the breach both sides of protective cover 1, have draw-in groove 14.Arc insulating apparatus is realized clamping with protective cover by buckle 23 and draw-in groove 14 and is coordinated.The independent use of protective cover and protective cover and arc insulating apparatus clamping are used in conjunction with, and can realize the preventing arc needs of circuit breaker different installation.
In addition, also can buckle be set on protective cover, draw-in groove is correspondingly set on arc insulating apparatus, arc insulating apparatus and arc insulating apparatus are realized clamping by draw-in groove and buckle and are coordinated.
Above-mentioned case study on implementation does not form any type of restriction to protection range of the presently claimed invention, and claims of the present invention have covered all modifications and changes.
