Background

In the prior art, with the continuous development of an intelligent power grid, the application of a microcomputer protection light tester of an intelligent substation is more and more common. The intelligent substation microcomputer protects the use of the optical tester, so that the on-site relay protection debugging work is more convenient, but the problems of connection, placement and storage of corresponding test optical fibers are solved, before each experiment, the optical fibers of the optical tester need to be connected, the optical tester comprises an optical tester end and a protection screen protection device back plate side, the optical fibers of different types can be used differently according to the optical port types of the back plates of various types of devices, in the connection process, the optical fibers cannot be placed orderly, and the optical fibers are inconvenient to check if the connected optical fibers need to be searched; after the test is finished, various optical fibers need to be dismantled and then arranged in a test coil, and when the next test is carried out, the optical fibers are connected and placed again as before. Therefore, when the optical fiber splicing device is used for field work, testers need to reconnect, arrange and place various functional optical fibers irregularly at each time, the problems that wiring influences test progress and the like easily occur to the workers, test errors are caused, and the smooth operation of the work is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the aforesaid not enough and provide a simple structure, be convenient for put, convenient to use, reliable scalable fiber test case of intelligent substation.

The technical solution of the utility model is that: scalable fiber test box of intelligent substation, its characterized in that includes a box, and the box has the lift case lid, has the pivot in the box, has a plurality ofly in the pivot and lean on and independent rotatory spiral cylinder, and the winding has two ends of a thread and winding opposite direction's optic fibre on every spiral cylinder, and two end of a thread optic fibre draw forth the mouth outside the box at the tail optical fiber on the box both sides respectively, and the tail optical fiber draws forth a mouthful top and corresponds every optic fibre and have the flexible locking button of optic fibre.

In the above-mentioned scheme, the first step of the method,

the two side surfaces of the box body are provided with optical fiber protective covers which are turned outwards, and tail optical fiber leading-out ports are arranged on the optical fiber protective covers.

Two opposite handles are projected from two sides of the upper part of the box body.

The device can be directly applied to relay protection tests, and can stretch or shrink test optical fibers according to test requirements, so that optical fibers of various types and functions are isolated from each other and do not interfere with each other. If the field work is with scalable optic fibre test box of intelligent substation, when experimental the end at every turn, experimental optic fibre can shrink, and every optic fibre can be mutually independent, can not produce the phenomenon that the test wire knotted, was crisscross. The device is convenient to arrange and reduces the time wasted in the early stage of the test. The test wire of the telescopic optical fiber test box achieves the effect of attractive appearance and neatness.

The utility model has the advantages that: 1. the multifunctional intelligent substation protection device can meet the test of various intelligent substation protection devices. 2. Can hold the optical fiber of multiple model function, conveniently carry. 3. The optical fibers at the two ends of the test box can be freely stretched and retracted, and the test box is very convenient to use. 4. The optical fiber head protection device is convenient for daily maintenance of the optical fiber and prevents the optical fiber head from being damaged due to the fact that the optical fiber head is not protected.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1-5, the part names are as follows: the optical fiber winding device comprises a box body handle 1, a box cover 2, a box body 3, a box body lock catch 4, an optical fiber telescopic locking button 5, a tail optical fiber leading-out port 6, an optical fiber protective cover 7, a winding roller 8, optical fibers 9, an optical fiber head 10, a rotating shaft 11, a spring 12, a slide rail 13, a locking button upper baffle plate 14 and a fixed locking buckle 15 on the box body.

Referring to fig. 1 and 2, scalable fiber test box of intelligent substation, including a box 3, box 3 has lift case lid 2 (the back is surveyed and is had the hinge, the front side has box hasp 4), there is pivot 11 in the box 3, have eight on the pivot 11 and lean on and independent rotatory spiral cylinder 8, the winding has two ends of a thread and winding opposite direction's optic fibre 9 on every spiral cylinder 8, two end of a thread optic fibre 9 respectively outside tail optical fiber outlet 6 on box 3 both sides stretches out box 3, can both ends elongate. And an optical fiber telescopic locking button 5 is arranged above the tail optical fiber leading-out opening 6 and corresponds to each optical fiber 9.
