Description
Technical field
The present invention relates to a kind of line case, specifically a kind of pressure test dedicated line case, be particularly suitable for electricity
In the pressure test of all kinds of electrical equipment of Force system.
Background technology
In recent years, continuous expansion along with electrical network scale, power system is to high voltage, Large Copacity, internet development, overhaul as the necessary means ensureing that power equipment health is run, it is related to the problems such as the consumption of the utilization rate of equipment, accident rate, service life, manpower, material resources and financial resources, and the overall efficiency of electric power enterprise.Electrical test, as the soldier at the head of a formation of maintenance, is born increasingly heavier mission, and pressure test is occupied very important status in high voltage electrical test.When carrying out pressure test work, teams and groups are required for using iron wire as aid every time.In work on the spot, it was found that three big shortcomings: first, work is all in testing ground temporarily by estimating from iron wire rod around taking short-circuit line, randomness is the biggest, before this has resulted in test, time is long, tidies up on-the-spot slow after test, often occurs being delayed the situation of test period；Second, iron wire gets rusty easily and easy tangled up and knotted, causes to throw out without care leaving about phenomenon seriously, can not get effectively putting in order and reclaiming, do not meet the requirement of lean production, and easily cause loose contact, easily affect result of the test after using；3rd: careless slightly it is possible to be retained on equipment by short-circuit line after test, once power transmission, consequence is hardly imaginable, does not meets safety in production requirement.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the present invention provides a kind of pressure test dedicated line case, scalable, location Special short line, can easily carry out pressure test short-circuit operation, effectively shorten the testing crew operating time, improve work efficiency；Simultaneously, it is to avoid iron wire easy tangled up and knotted easily loses the potential safety hazard caused,
Decrease security risk.
The present invention realizes with following technical scheme: a kind of pressure test dedicated line case, including a dismountable casing, installing a support shaft at the center of casing, support shaft is installed a reel rotated around support shaft, reel is provided with three wide wire casings for placing wire；It is correspondingly provided with hole, multiple location on one side end face of reel, opposite side end face is provided with handle；One alignment pin matched with circular hole is installed on casing；Three line outlets it are additionally provided with on casing.
The invention has the beneficial effects as follows: according to scalability principle, testing crew is the most firmly rapidly completed short circuit operation, without again by estimating to intercept iron wire before test, the operation Lou taking and being wound around iron wire is it also avoid after test, it is thus possible to the time before effective shortening test and the clearance time after test, improve work efficiency, reduce labor intensity, improve test reliability.Simultaneously, before avoiding iron wire be always easily deformed, tangled up and knotted, can not the phenomenon of repeatedly recycling, meet the different electric pressure difference electrical equipment different requirements to shorting stub length, the utilization rate making extension type shorting stub is greatly improved, there is popularization, largely save the spending of short-circuit line, improve economic benefit.

Detailed description of the invention
As illustrated in fig. 1 and 2,A kind of pressure test dedicated line case has a dismountable casing 1, one support shaft 3 is installed at the center of casing 1, installing a reel 2 rotated around support shaft in support shaft 3, described reel 2 is ring-type, and reel 2 has three wide wire casings 21 for placing wire；It is correspondingly provided with hole, multiple location 22 on one side end face of reel, opposite side end face is provided with handle 6；One alignment pin 5 matched with circular hole is installed on casing 1.Three line outlets 7 it are additionally provided with on casing.
As in Figure 3-5, described casing is from supporting base 11 and the shell 12 that coordinates with it forms；Described support base 11 is " L " type, is provided with multiple screwed hole 6 in the edge junction supporting base 11 and shell 12, is arranged on support base by shell with screw.
Described support shaft 3 is arranged on " L " type and supports the riser center of base 11, and described alignment pin is arranged on by spring 4 and supports below the riser of base 11.The structure of alignment pin as shown in figure 12, by alignment pin and hole, location, it is achieved the location of the existing length to U, V, W shorting stub.
Wherein, the described base 11 that supports uses the corrosion resistant plate of 6mm to make, a height of 319mm, wide 180mm, limit thickness 16mm.
As shown in figs 6-8, being arranged on above the both sides of shell of described line outlet 7 symmetry.
The cross section of described reel 2 is circular (as shown in FIG. 10 and 11) or octagon (as shown in Figs. 13 and 14).The width of described wire casing 21 is 35mm.Hole 22,8 location it is uniformly provided with on one side end face of reel.
As described in Fig. 1 and Fig. 9, described support shaft 3 realizes 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 divides fixed main shaft for support shaft and reel, and another part is that demountable lower box completes the replacing to short-circuit line and breakdown maintenance.By the rotation driving drive reel of handle, reel is provided with the wire casing of three wires, can effectively avoid the mutual crosstalk of U, V, W three-phase conducting wire, owing to one end of three-phase conducting wire is fixed on the same place of reel, therefore can ensure that the wire of outlet and take-up is isometric.The location of the length to U, V, W shorting stub can be realized by the use in 8 holes, location and alignment pin.Shorting stub uses the quality of soft copper, it is to avoid flexural deformation after using, the puzzlement being not easily recycled.The alligator clamp of collocation suitable size, is reliably connected with electrical equipment, it is ensured that test accuracy.
Operate for convenience, from the joint of three line outlets shorting stub out, one alligator clamp is installed.When carrying out vacuum circuit breaker pressure test short-circuit operation, first testing crew pulls open alignment pin, and swinging handle carries out unwrapping wire.The shorting stub alligator clamp of stretching is clipped on chopper U, V, W three-phase contact by another testing crew, and after short-circuit operation, close alignment pin, shorting stub is fixed, and forbids stretching, i.e. completes whole short-circuit operation.
