The portable telescopic test wire box has the advantages of being convenient to carry and use, and capable of effectively protecting the test wire.
Description
Technical field
The utility model relates to the utensil of retractable cable, particularly the retractable cable device of relay protection of power system test wire.
Background technology
At present, when constantly releasing novel high-performance microcomputer protective relay proving installation, do not have any improvement with the closely-related test wire of relay protection test work.The relay protection of power system test wire generally is made up of outsourcing insulation through stranded stranded copper wire.Because test wire is long, the time spent is not placed in the line bag after need rolling, and the line bag is flexible packaging, can not well play the effect of protection test line, and normal and other article load in mixture, and has increased wearing and tearing.In the process of the test, because debugging field activity complicated condition also can not get the actv. protection.Thereby often the problem owing to test wire increases burn in period, sometimes even delay the duration.
The utility model content
The purpose of the utility model provides a kind of portable telescopic test wire case that is convenient for carrying and uses.
This later-model purpose is achieved in that a kind of portable telescopic test wire case; The left and right two ends that comprise test wire all are connected with plug; Be fixed with an axis between the top board of rectangular casing and the base plate, change box and be positioned at casing, change box and be arranged on the axis rotationally; An end that is positioned at the disc spring that changes box is fixed on the axis, and the other end is fixed on to be changeed on the box internal face; Said test wire is wound on to be changeed on the box, and test wire is opposite at the coil direction that changes coiling direction and disc spring on the box, and draw beyond the casing from the left wire hole and the right wire hole of casing respectively at the left and right two ends of test wire.
Above-mentioned casing is a plurality of, and a plurality of casings are fixedly connected or detachable being connected as one, and all left wire holes of a plurality of casings are positioned at a side, and the right wire hole of all of a plurality of casings is positioned at opposite side.
The left and right side who changes box in the above-mentioned casing is provided with the pulley or the roller of drawing direction as the limit assay line.
The beneficial effect of the utility model is: this portable telescopic test wire case adopts telescopic automatic spiral, so that test wire is designed with the mode that the line bag combines, and inspection easily; Be convenient for carrying, and test wire can be effectively protected the probability that the minimizing test wire damages; Thereby can not increase burn in period, reduce the setup time before going on business yet, improve work efficiency because of the problem of test wire; And increased service life, reduced the business equipment maintenance cost.
This portable telescopic test wire case is specially adapted to the relaying debugging verification work of various occasions, has bigger dissemination at power department.
Description of drawings
Fig. 1 is the constructional drawing of this novel one unit casing.
Fig. 2 is the schematic perspective view after a plurality of casing assembly unit shown in Figure 1.
The specific embodiment
Fig. 1 illustrates; The left and right two ends of test wire 5 all are connected with plug; Be fixed with an axis 2 between the top board of rectangular casing 1 and the base plate, change box 4 and be positioned at casing 1, change box 4 and be arranged on rotationally on the axis 2; An end that is positioned at the disc spring 3 that changes box 4 is fixed on the axis, and the other end is fixed on to be changeed on box 4 internal faces; Said test wire 5 is wound on to be changeed on the box 4, and test wire is opposite at the coil direction that changes coiling direction and disc spring on the box, and draw beyond the casing from the left wire hole 1a and the right wire hole 1b of casing 1 respectively at the left and right two ends of test wire.The left and right side who changes box 4 in the said casing 1 is provided with the first pulley 6a, the second pulley 6b or the roller of drawing direction as the limit assay line.Referring to Fig. 2, casing 1 is a plurality of, and a plurality of casings are fixedly connected or detachable being connected as one, and all left wire hole 1a of a plurality of casings are positioned at a side, and the right wire hole 1b of all of a plurality of casings is positioned at opposite side.All be connected with plug on two of test wire leads among Fig. 2.
This portable telescopic test wire case is to improve test wire with the mode that the line bag combines, test wire adopts the telescopic automatic spiral design of symmetry, and practical implementation is following:
1, test wire and disc spring formula are changeed box and combine, form the test wire case, no longer need traditional line bag.The test wire case is rigid package, can actv. protection test line.The unification of case line need not periodic cleaning, and convenient inspection reduces the setup time before going on business, and has improved work efficiency.
2, the test wire case is made up of the individual unit box of nine (or ten) (being the test wire lattice), but such line case meet requirements is imported the test of three phase current, three phasevoltage and voltage of system simultaneously.Design ten line lattice, mainly be considered as subsequent use.
3, each test wire lattice all can independent installing/dismounting, changes separately to make things convenient for certain line lattice to damage, thereby effectively reduces maintenance cost.
4, test wire adopts the telescopic automatic spiral design of symmetry, and line case two ends are as broad as long, are retractable to suitable length during debugging, avoids long and drags on ground impairedly, and the debugging test wire rollback line case that finishes can not twine mutually, reduces unnecessary wearing and tearing.
