Abstract
The embodiment of the utility model discloses a shorting device, comprising a wire spool, a wire and metal collets, wherein three metal collets which are respectively connected to the two ends and any central location of the wire are provided, and the wire is wound on the wire spool. In comparison with one fuse in the prior art, the shorting device disclosed by the utility model is increased in size, therefore the shorting device is more obvious, and not easily ignored by a tester so that the short circuit phenomenon because a shorting stub is not taken off in the power transmission process is prevented, and safety factor is improved; the wire spool, the wire and the metal collets are all made of common materials, so the cost of the shorting device is low; and the metal collets can be directly clipped on three phases of a vacuum switch so that a shorting operation is simpler and faster, and working efficiency is improved.
Description
Technical field
The utility model relates to the electric power apparatus examination technical field, relates in particular to a kind of short-circuit device.
Background technology
When the maintenance power equipment, usually need to carry out the vacuum switch test.In the process of the test, require the three-phase of vacuum switch to be in the short circuit state.In the practical application, the common practice that realizes short circuit is the three-phase that directly connects vacuum switch with a fuse.There is huge potential safety hazard in this way: fuse is tiny, and is unobvious, after test is finished, very easily forgotten on switch by the test personnel, causes line short when sending electricity, causes major accident.
The utility model content
In view of this, the utility model embodiment purpose is to provide a kind of short-circuit device, to solve easily the pass into silence problem of short circuit on switch, when causing sending electricity of existing fuse short circuit mode.
For achieving the above object, the utility model embodiment provides following scheme:
A kind of short-circuit device comprises wire spool, wire and metal collet; Described metal collet has 3, is connected to the arbitrary position in two ends and middle part of described wire; Described wire is wound on the described wire spool.
Preferably, also be provided with anti-error hook on the described wire spool.
Preferably, described wire is annealed copper wire.
Can find out from above-mentioned technical scheme, the utility model is made short-circuit device by wire spool, wire and metal collet, a fuse with respect to the prior art use, volume increases, so that short-circuit device is more obvious, be difficult for being ignored by the test personnel, thereby do not take off the short circuit phenomenon that causes because of shorting stub when having avoided sending electricity, safety coefficient improves.In addition, wire spool, wire and metal collet are common materials, and cost is extremely low; Metal collet can directly be clipped on the three-phase of vacuum switch, makes more simple and fast of short-circuit operation, has improved work efficiency.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of short-circuit device, to solve easily the pass into silence problem of short circuit on switch, when causing sending electricity of existing fuse short circuit mode.
With reference to Fig. 1, the short-circuit device that the utility model embodiment provides comprises wire spool 1, wire 2 and metal collet; Wherein, metal collet has 3, i.e. the first metal collet 31, the second metal collet 32, the 3rd metal collet 33 are connected to the arbitrary position in two ends and middle part of wire 2; Wire 2 is wound on the wire spool 1.When carrying out switch test, only need 3 metal collets are clipped on the three-phase of vacuum switch, can realize short circuit.
Concrete, above-mentioned short-circuit device can be made by the following method: optional position at wire 2 middle parts, and such as the midpoint of wire 2, with wire 2 bendings.Two ends and bending place at wire 2 respectively connect a metal collet, and bending end is fixed on the wire spool 1, from the bending place, wire 2 are wrapped on the wire spool 1.Wire spool 1 can adopt the drum of the common cables such as fuse, to save cost.
By said structure as can be known, the utility model embodiment makes short-circuit device by wire spool, wire and metal collet, a fuse with respect to the prior art use, volume increases, so that short-circuit device is more obvious, be difficult for being ignored by the test personnel, thereby do not take off the short circuit phenomenon that causes because of shorting stub when having avoided sending electricity, safety coefficient improves.In addition, wire spool, wire and metal collet are common materials, and cost is extremely low; Metal collet can directly be clipped on the three-phase of vacuum switch, makes more simple and fast of short-circuit operation, has improved work efficiency.
Referring to Fig. 2, the short-circuit device that another embodiment of the utility model provides comprises wire spool 1, wire 2, metal collet and anti-error hook 4; Wherein, metal collet has 3, i.e. the first metal collet 31, the second metal collet 32, the 3rd metal collet 33 are connected to the arbitrary position in two ends and middle part of wire 2; Wire 2 is wound on the wire spool 1; Anti-error hook 4 is fixed on the wire spool 1.
As shown in Figure 3, during test, the A that the first metal collet 31 is clipped in vacuum switch 5 goes up mutually, and the second metal collet 32 is clipped in C and goes up mutually, and the 3rd metal collet 33 is clipped in B and goes up mutually.Anti-error hook 4 hangs on the connecting line 6 of testing equipment nearby.
The short-circuit device that present embodiment provides owing to be connected with the connecting line of testing equipment, in off-test, when removing this connecting line, is naturally noted by the test personnel, thereby has eliminated the potential safety hazard of existing fuse short circuit mode.
In addition, the distance between the three-phase of vacuum switch is not quite similar, and the fuse short circuit need to be selected according to actual range the length of fuse.And among all embodiment of the present utility model, because wire 2 is to be wrapped on the wire spool 1, so the first metal collet 31 and the second metal collet 32 extensile length are adjustable: the distance between the three-phase of vacuum switch hour, wire 2 is twined several circles more on wire spool 1, the first metal collet 31 and the second metal collet 32 are clipped on all the other two-phases just, avoid wire redundant; When the distance between the three-phase of vacuum switch is larger, then reduce the winding number of turn of wire 2 on wire spool 1, the first metal collet 31 and the second metal collet 32 are clipped on all the other two-phases just.Therefore, the short-circuit device that provides of the utility model embodiment is applicable to short circuit requirement in any case.
Among above-mentioned all embodiment, wire all can adopt annealed copper wire, and such as the enameled wire after the annealing, quality is soft, is convenient to crooked the winding.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
