Abstract
The invention discloses a wire box special for a voltage-withstanding test and relates to a wire box. The wire box comprises a detachable box body. A supporting shaft is arranged in the center of the box body, a coiling wheel which rotates around the supporting shaft is arranged on the supporting shaft, and three width-equal wire grooves for placing of lead wires are formed in the coiling wheel. A plurality of locating holes are correspondingly formed in the end face of one side of the coiling wheel, and a handle is arranged on the end face of the other side of the coiling wheel. A locating pin matched with a circular hole is arranged on the box body. Three wire outlets are formed in the box body. The wire box has the advantages that a special short circuit wire can be stretched and located, voltage-withstanding test short circuit operation can be carried out easily, operation time of testing personnel is effectively shortened, working efficiency is improved, meanwhile, potential safety hazards caused by the fact that iron wires can be easily wound, knotted and lost are avoided, and safety risks are reduced.
Description
Technical field
The present invention relates to a kind of line case, specifically a kind of withstand voltage test industrial siding case, is particularly suitable for electricity
In the withstand voltage test of all kinds of electrical equipments of power system.
Background technology
In recent years, continuous expansion along with electrical network scale, electric system is to high voltage, large capacity, internet development, maintenance is as the necessary means that guarantees the healthy operation of power equipment, be related to utilization factor, accident rate, the serviceable life of equipment, the consumption of manpower, material resources and financial resources, and the problems such as overall efficiency of electric power enterprise.Electrical test, as the soldier at the head of a formation of maintenance, is being born more and more heavier mission, and withstand voltage test occupies very important status in high-voltage electrical apparatus test.While carrying out withstand voltage test work, teams and groups all need to use iron wire as aid at every turn.In work on the spot, found three large shortcomings: the first, in work, be all temporarily by estimating from iron wire rod around getting short-circuit line in testing ground, randomness is very large, before this has just caused test setup time long, after test, tidy up on-the-spotly slow, often there is incuring loss through delay the situation of test period; The second, iron wire gets rusty easily and easy tangled up and knotted, causes to throw out that to leave about phenomenon serious without care, can not get effectively putting in order and reclaiming after use, does not meet the requirement of lean production, and easily causes loose contact, easily affects test findings; The the 3rd: test is careless slightly afterwards just may be retained in short-circuit line on equipment, once power transmission, consequence is hardly imaginable, does not meet safety in production requirement.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the invention provides a kind of withstand voltage test industrial siding case, scalable, location Special short line, can carry out withstand voltage test short-circuit operation like a cork, effectively shortens the testing crew running time, increases work efficiency; Meanwhile, avoided the easy tangled up and knotted of iron wire easily to lose the potential safety hazard causing,
Reduced security risk.
The present invention realizes with following technical scheme: a kind of withstand voltage test industrial siding case, comprise a dismountable casing, at the center of casing, one back shaft is installed, a reel rotating around back shaft is installed on back shaft, reel be provided with three wide for placing the wire casing of wire; On one side end face of reel, correspondence is provided with a plurality of pilot holes, on opposite side end face, handle is installed; One register pin matching with circular hole is installed on casing; On casing, be also provided with three line outlets.
The invention has the beneficial effects as follows: according to scalability principle, testing crew accurately firmly completes short circuit operation fast, test is front without intercepting iron wire by estimation again, after test, also avoided leaking the operation of getting and be wound around iron wire, thereby can effectively shorten the clearance time after setup time before test and test, increase work efficiency, reduce labor intensity, improve test reliability.Simultaneously, the always easily distortion of former iron wire, tangled up and knotted, the phenomenon of recycling have repeatedly been avoided, the different requirements of the different electrical equipments of different electric pressures to shorting stub length have been met, the utilization factor of extension type shorting stub is improved greatly, there is popularization, the spending of largely having saved short-circuit line, has improved economic benefit.

Embodiment
as illustrated in fig. 1 and 2,a kind of withstand voltage test industrial siding case has a dismountable casing 1, one back shaft 3 is installed at the center of casing 1, one reel 2 rotating around back shaft is installed on back shaft 3, and described reel 2 is ring-type, on reel 2, have three wide for placing the wire casing 21 of wire; On one side end face of reel, correspondence is provided with a plurality of pilot holes 22, and handle 6 is installed on opposite side end face; One register pin matching with circular hole 5 is installed on casing 1.On casing, be also provided with three line outlets 7.
As in Figure 3-5, described casing is comprised of base for supporting 11 and the shell 12 that is mated; Described base for supporting 11 is " L " type, in the limit portion junction of base for supporting 11 and shell 12, is provided with a plurality of threaded holes 6, with screw, shell is arranged on base for supporting.
Described back shaft 3 is arranged on the riser center of " L " type base for supporting 11, and described register pin is arranged on the riser below of base for supporting 11 by spring 4.The structure of register pin as shown in figure 12, by register pin and pilot hole, realizes the existing location to the length of U, V, W shorting stub.
Wherein, described base for supporting 11 is used the corrosion resistant plate of 6mm to make, and height is 319mm, wide 180mm, the thick 16mm in limit.
As shown in Fig. 6-8, the top, both sides that is arranged on shell of described line outlet 7 symmetries.
The cross section of described reel 2 is circular (as shown in FIG. 10 and 11) or octagon (as shown in Figure 13 and 14).The width of described wire casing 21 is 35mm.On one side end face of reel, be evenly provided with 8 pilot holes 22.
As described in Fig. 1 and Fig. 9, described back shaft 3 is realized support and the rotation of reel by the interference fit of four bearings.
The present invention is designed by two parts split, and a part of for back shaft and reel divide fixed main shaft, another part is that demountable lower box completes the replacing of short-circuit line and breakdown maintenance.By the driving of handle, drive the rotation of reel, reel is provided with the wire casing of three wires, can effectively avoid mutually crosstalking of U, V, W three-phase conducting wire, because one end of three-phase conducting wire is fixed on the same place of reel, so can guarantee that the wire of outlet and take-up is isometric.Use by 8 pilot holes and register pin can realize the location to the length of U, V, W shorting stub.Shorting stub adopts the quality of soft copper, flexural deformation after having avoided using, difficult puzzlement of reclaiming.The crocodile clip of collocation suitable size, is reliably connected with electrical equipment, has guaranteed test accuracy.
For handled easily, from jiont treatment one crocodile clip of three line outlets shorting stub out.When carrying out vacuum circuit breaker withstand voltage test short-circuit operation, first testing crew pulls open register pin, and swinging handle carries out unwrapping wire.Another testing crew is clipped in the shorting stub of stretching on isolating switch U, V, W three-phase contact with crocodile clip, and after short-circuit operation, the register pin that closes, fixes shorting stub, forbids stretching, and has completed whole short-circuit operation.
