Description

A kind of outdoor high-voltage drop type fuse
Technical field
The utility model relates to field of circuit breakers more particularly to a kind of outdoor high-voltage drop type fuses.
Background technique
At present outdoors high-voltage electricity in use, due to needing to protect high-tension line, will use fuse, Fuse fuses when short circuit occurs for route, disconnects circuit, and current fuse has one is fuse switch, when When short circuit current passes through fuse failure, electric arc is generated, the vulcanized fiber tube of cartridge fuse liner generates a large amount of gas under arcing Because cartridge fuse upper end is shut, gas is sprayed to lower end, blows out electric arc.Due to fuse failure, the upper lower moving contact of cartridge fuse is lost The fastening force for removing fuse, under the action of cartridge fuse self gravity, cartridge fuse falls rapidly, disconnects circuit, cuts off faulty section Route or faulty equipment.But above-mentioned apparatus needs service personnel to repair after disconnecting circuit, and since fuse is logical It is often mounted on higher position, is difficult to determine bottom to be which fuse blows from external observation fuse, in turn results in work Make efficiency reduction, increases the difficulty of maintenance work.Therefore, it is not easily distinguishable and just seems after solving the problems, such as fuse switch work It is particularly important.
Utility model content
In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kind of outdoor high-voltage drop type fuse, By indicating that block follows cartridge fuse, when cartridge fuse falls, indicate that the position of block changes, and then judge that fuse is It is no already off, and assist keeping result more intuitive with contact sensor and alarm lamp, solving fuse switch work After the problem of not being easily distinguishable.
The utility model provides a kind of outdoor high-voltage drop type fuse, including cartridge fuse, the cartridge fuse top It is provided with upper bracket, the cartridge fuse lower part is provided with lower bracket, and the cartridge fuse is connected to upper branch by slip collar On frame and lower bracket, the cartridge fuse top is fixedly installed instruction block, and when cartridge fuse fusing is fallen, instruction block is followed Cartridge fuse is fallen.
Further improvement lies in that: contact sensor is provided on the lower bracket, the contact sensor setting is indicating Immediately below block, the upper bracket is provided with alarm lamp, and the contact sensor is associated with alarm lamp.
Further improvement lies in that: it is provided with telescopic cylinder between the upper bracket and lower bracket, is adjusted by telescopic cylinder Spacing between upper bracket and lower bracket.
Further improvement lies in that: the contact sensor lower end is provided with buffer spring, the buffer spring lower end setting There is adjusting block, by adjusting cylinder connection between the adjusting block and lower bracket.
Further improvement lies in that: it is provided with cooling blower on the upper bracket, position biography is provided on the cartridge fuse Sensor, the cooling blower are associated with position sensor.
The beneficial effects of the utility model are:, when cartridge fuse falls, indicating block by indicating that block follows cartridge fuse Position change, and then judge whether fuse already off, and assist making result with contact sensor and alarm lamp More intuitive, personnel easy to repair judge whether fuse disconnects, and by buffer spring and adjust block protection sensing contact Device, and electric arc is blown out from external auxiliary by cooling blower, improve security and stability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1- cartridge fuse, 2- upper bracket, 3- lower bracket, 4- slip collar, 5- indicate block, 6- contact sensor, 7- Alarm lamp, 8- telescopic cylinder, 9- buffer spring, 10- adjusting block, 11- adjust cylinder, 12- cooling blower, 13- position sensor.
Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment further detailed It states, the present embodiment is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
As shown in Figure 1, a kind of outdoor high-voltage drop type fuse is present embodiments provided, including cartridge fuse 1, it is described molten 1 top of fracture of wire pipe is provided with upper bracket 2, and 1 lower part of cartridge fuse is provided with lower bracket 3, and the cartridge fuse 1 passes through sliding Lantern ring 4 is connected on upper bracket 2 and lower bracket 3, and 1 top of cartridge fuse is fixedly installed instruction block 5, when cartridge fuse 1 Instruction block 5 follows cartridge fuse 1 to fall when fusing is fallen.Contact sensor 6 is provided on the lower bracket 3, the contact passes For the setting of sensor 6 immediately below instruction block 5, the upper bracket 2 is provided with alarm lamp 7, the contact sensor 6 and 7 phase of alarm lamp Association.It is provided with telescopic cylinder 8 between the upper bracket 2 and lower bracket 3, upper bracket 2 and lower bracket are adjusted by telescopic cylinder 8 Spacing between 3.6 lower end of contact sensor is provided with buffer spring 9, and 9 lower end of buffer spring is provided with adjusting block 10, it is connected between the adjusting block 10 and lower bracket 3 by adjusting cylinder 11.It is provided with cooling blower 12 on the upper bracket 2, Position sensor 13 is set on the cartridge fuse 1, and the cooling blower 12 is associated with position sensor 13.Pass through instruction Block 5 follows cartridge fuse 1, and when cartridge fuse 1 falls, whether the position of instruction block 5 changes, and then judge fuse Through disconnecting, and assist keeping result more intuitive, personnel easy to repair judge that fuse is with contact sensor 6 and alarm lamp 7 No disconnection, and contact sensor 6 is protected by buffer spring 9 and adjusting block 10, and pass through cooling blower 12 from external auxiliary Electric arc is blown out, security and stability is improved.
