Description
Technical field
This utility model relates to field of switch equipment, the disconnecting switch interlocking of a kind of breaker anti-maloperation
Device.
Background technology
The moving contact at cartridge fuse two ends relies on fuse (melt) to fasten, after upper moving contact is pushed " duckbilled " projection,
The upper static contact that phosphorus bronze sheet etc. are made heads on moving contact, so cartridge fuse to be stuck in " duckbilled " securely inner.When short circuit current leads to
When crossing fuse failure, producing electric arc, the vulcanized fiber tube of cartridge fuse liner produces substantial amounts of gas because of on cartridge fuse under arcing
End is shut, and gas sprays to lower end, blows out electric arc.Due to fuse failure, what the upper lower moving contact of cartridge fuse lost fuse is
Clamp force, under the effect of cartridge fuse self gravitation and upper and lower static contact spring leaf, cartridge fuse falls rapidly, makes circuit disconnect, cuts
Except faulty section circuit or faulty equipment.
Fuse switch electric conductivity in use for some time is poor, it is difficult, easy to fall off to close a floodgate, it is tactile often to burn out for tradition
Head and fusion tube, fault rate is high.Not only add the workload of attendant, and too increase maintenance cost
Summary of the invention
The deficiency existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of breaker anti-maloperation
Disconnecting switch interlock.
To achieve these goals, this utility model be the technical scheme is that a kind of breaker anti-maloperation every
From switch interlocking device, including breaker body and disconnecting switch, described breaker body is provided with outer housing, described disconnecting switch
Being bolted insulating ceramics one end, the described insulating ceramics other end is fixed with angle steel and is fixed on angle by nut
Expansion link on steel, described expansion link connects has connecting plate, described breaker body shell to be provided with latch lever, described latch lever
In separated and be respectively equipped with screw at open end, described screw is provided with nut, and described nut is fixed with spring by tabletting,
Described connecting plate forms interlock with latch lever.
Preferably, it is characterised in that: described breaker body outer housing is provided with temperature sensor, and described temperature sensor is even
It is connected to LED display.
Preferably, described breaker body outer housing is provided with temperature sensor, and described temperature sensor connects has LED to show
Screen.
Preferably, described disconnecting switch thickness is 1-2cm.
Preferably, it is provided with cushion between described spring and tabletting.
Use after technique scheme, this utility model the most advantageously:
High voltage fuse described in the utility model, described installing plate is provided with fan, can effectively reduce fusing
Temperature during device work, described upper contact head fixes ferrum and is provided with thermometer, staff can be allowed to grasp the temperature of fuse,
Prevent from scalding, outside described fusion tube, be surrounded by protection against electric shock layer, be possible to prevent staff to occur when maintenance unexpected, described rain-proof cover
It is provided with flourescent sheet, convenient when night can overhaul fuse.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is connecting rod schematic diagram.
In reference: 1-breaker body, 2-disconnecting switch, 3-outer housing, 4-insulating ceramics, 5-angle steel, 6-expansion link,
7-connecting plate, 8-latch lever, 9-screw, 10-nut, 11-tabletting, 12-spring.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, the most therefore limits protection model of the present utility model
Enclose.
Embodiment, as depicted in figs. 1 and 2, the disconnecting switch interlock of a kind of breaker anti-maloperation, including chopper
Body 1 and disconnecting switch 2, described breaker body 1 is provided with outer housing 3, it is characterised in that described disconnecting switch 2 passes through bolt
Being fixed with insulating ceramics 4 one end, described insulating ceramics 4 other end is fixed with angle steel 5 and is fixed on angle steel 5 by nut
Expansion link 6, described expansion link 6 connects has connecting plate 7, described breaker body 1 shell to be provided with latch lever 8, described latch lever 8
In separated and be respectively equipped with screw 9 at open end, described screw 9 is provided with nut 10, and described nut 10 is solid by tabletting 11
Surely having spring 12, described connecting plate 7 to form interlock with latch lever 8, described breaker body 1 outer housing is provided with temperature sensing
Device, described temperature sensor connects LED display, is provided with protection against electric shock layer, described isolation inside described breaker body 1 outer housing
Switching 2 thickness is 1-2cm, is provided with cushion between described spring 12 and tabletting 11, when disconnecting switch 2 normally closes, connects
Plate 7 can not stop latch lever 8 to move, the normal work of chopper isolation interlocking.When disconnecting switch 2 closes not in place, latch lever 8
Connected plate 7 blocks and can not move, and breaker closing proceeds, and at latch lever 8, spring 12 is compressed, and breaker closing becomes
Merit, thus avoid the generation of accident.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
