Problems solved by technology
In the relay repair test, it can be known from some media such as safety briefings and accident reports that many accidents occurred due to misconnection, mishandling, and wrong intervals during work, posing a serious threat to the safe operation of substations.
The losses caused are huge, ranging from light outages on one line to serious power outages in large areas, etc...
[0003] For a long time, when we are repairing and testing the secondary equipment, according to the safety measures of the work arrangement, we hang the signboard of "this work" on the repaired device, and in the running device The "in operation" signboard is hung on the top, and other devices and terminal blocks are exposed in the working range; sometimes the staff is easy to knock off the signboard, and the small wire of the instrument used for repair is easy to accidentally touch the line post on the device when taking it out , wire ends, and the secondary devices are arranged densely in the disk, which may easily lead to misconnection at the wrong interval, and the occurrence of mistakenly dismantling the secondary line, etc.

Embodiment Construction
[0010] Such as figure 1 As shown, the protective curtain device includes a frame 1, a transverse winder 2, a longitudinal winder 3, a molded curtain 4 and a longitudinal curtain 5, and a transverse winder is respectively installed at one transverse end and a longitudinal end of the frame 1. 2. The longitudinal winder 3, the mold direction cloth 4 and the longitudinal cloth 5 are wound on the transverse winder 2 and the longitudinal winder 3 respectively, forming a curtain cloth as a whole.
[0011] When repairing and testing, fix the curtain cloth device on the plate, turn the horizontal winder 2 and the longitudinal winder 3, and let the mold direction cloth 4 and the longitudinal cloth 5 move up and down, left and right, and leave corresponding windows for the cloth curtain , the devices that should be repaired and tested are left to the repairing personnel, and other non-repairing devices are completely covered.

Description
technical field [0001] The invention relates to a protective curtain, in particular to a special protective curtain device for relay repair and testing. Background technique [0002] When it comes to safety in the power supply system, everyone knows its importance. In the relay repair test, it can be seen from some media such as safety briefings and accident reports that many accidents occurred due to misconnection, mistouching, and wrong intervals during work, posing a serious threat to the safe operation of substations. The losses caused are huge, ranging from light outages of one line to serious power outages in large areas, etc... [0003] For a long time, when we repair and test the secondary equipment, according to the safety measures of the work arrangement, we hang the "this work" signboard on the repaired device, hang the "running" signboard on the running device, and other devices and terminal blocks. It is exposed in the scope of work; sometimes the staff is eas...
