Abstract
The invention discloses a kind of middle Disjunction type fuse switch, including upper terminals（1）, upper static contact（2）, upper moving contact（3）, pipe cap（4）, operation ring（5）, fusion tube（6）, fuse（7）, lower moving contact（8）, lower static contact（9）, lower terminals（10）, insulating support（11）, metal mounting plate（12）And insulator（13）；Wherein insulating support（11）Insulator（13）Be divided into two sections, respectively with metal mounting plate（12）Connection；Metal mounting plate（12）One end and insulating support（11）Connection, other end ground connection.Work as insulating support（11）Insulaion resistance do not reach standard requirement, ground short circuit signal will be produced, whole system is operated a switch power-off.
Description
Technical field
The present invention relates to fuse field, more particularly, to a kind of middle Disjunction type fuse switch.
Background technology
Fuse switch is 10kV distribution lines branch line and a kind of the most frequently used protective switch of the short circuit of distribution transformer,
It has the characteristics that economical, easy to operate, adaptation outdoor environment is strong, is widely used in 10kV distribution lines and distribution transformer
Device primary side is used as protecting and carry out equipment throwing, cut operation.
But there occurs the ordinary accident that power supply station's employee's upper stage repairing is got an electric shock and died in actual application, it is real
Test results verification B phase fuse switch insulating support internal breakdowns.It can thus be appreciated that when stand works, in part, drop type melts
Disconnected device is in the case where fuse tube has pulled open, if insulating support causes to insulate by the thunderbolt reason such as internal breakdown or aging
Support turns on, and staff is grounded without electrical verification during rushing to repair, and direct upper stage work will touch charging equipment by mistake and cause
The person gets an electric shock.
The content of the invention
To realize above goal of the invention, the technical scheme of use is：A kind of middle Disjunction type fuse switch, including it is upper
Terminals 1, upper static contact 2, upper moving contact 3, pipe cap 4, operation ring 5, fusion tube 6, fuse 7, lower moving contact 8, lower static contact 9, under
The insulator 13 of terminals 10, insulating support 11, metal mounting plate 12 and insulator 13, wherein insulating support 11 is divided into two sections,
It is connected respectively with metal mounting plate 12；The one end of metal mounting plate 12 is connected with insulating support 11, other end ground connection.
In such scheme, the insulator 13 of the insulating support 11 of fuse switch is divided into two sections, uses metal mounting plate
12 connect two sections of insulators 13.Metal mounting plate 12 serves the effect that plate is fixedly mounted, meanwhile, by metal mounting plate
12 ground connection, when the insulator 13 in insulating support 11 is punctured or aging causes not reach the standard requirement of insulaion resistance by thunder and lightning,
Metal mounting plate 12 is turned on insulator 13, produces ground short circuit signal, and whole system is operated a switch power-off.
Compared with prior art, the beneficial effects of the invention are as follows：
1）It is adapted to the installation of various stands and distribution branch line；
2）Fixed metal plate is grounded, and increases operational security；
3）The structure of existing 10KV fuse switches is improved, designs and develops that cost is low, and technology easily replicates popularization.
Brief description of the drawings
Fig. 1 is fuse structure figure；
Fig. 2 is fuse explosive view.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；
Below in conjunction with drawings and examples, the present invention is further elaborated.
Embodiment 1
Fig. 1, Fig. 2 are refer to, Fig. 1 is fuse structure figure, and Fig. 2 is fuse explosive view.
A kind of middle Disjunction type fuse switch, including upper terminals 1, upper static contact 2, upper moving contact 3, pipe cap 4, behaviour

End is connected with insulating support 11, other end ground connection.
The air gap is left between wherein described two insulators 13.
Wherein described insulator 13 is the member structure of epoxy resin material.
Wherein described metal mounting plate 12 is connected one end with insulating support 11 and moved up and down.
Wherein described metal mounting plate 12 is connected one end covering insulating material with insulating support 11.
In use, the insulator 13 of the insulating support 11 of fuse switch is divided into two sections, uses metal mounting plate
12 connect two sections of insulators 13.Metal mounting plate 12 serves the effect that plate is fixedly mounted, meanwhile, by metal mounting plate
12 ground connection, when the insulator 13 in insulating support 11 is punctured or aging causes not reach the standard requirement of insulaion resistance by thunder and lightning,
Metal mounting plate 12 is turned on insulator 13, produces ground short circuit signal, and whole system is operated a switch power-off.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not pair
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.It is all this
All any modification, equivalent and improvement made within the spirit and principle of invention etc., should be included in the claims in the present invention
Protection domain within.
