Description

Spool formula red cloth curtain

Technical Field

The utility model relates to a power maintenance technical field, in particular to spool formula red cloth mantle.

Background

The red cloth mantle is mainly used for transformer substation maintenance work, reminds maintainer equipment in live-line operation. The red cloth mantle can inform the position that the danger source was located very clearly with its striking color and typeface, avoids because the dangerous phenomenon such as electrified interval is gone into to the mistake that factors such as switchgear "five prevent" functional insufficiency or operating personnel energy dispersion influence emergence, mistake branch mistake closes the switch, effectual emergence that prevents the accident. The red cloth mantle used in the operation and maintenance at present is divided into a magnetic attraction fixed type, a rope tied fixed type and a nylon bonding fixed type.

The use, the recovery and the warning effect of present red cloth mantle all have more problems.

1. When outdoor safety measures are arranged, a large-area flat metal wall is rarely used for the magnetic suction type red cloth mantle to adsorb, the red cloth mantle is often required to be fixed on an equipment support, the lengths of the rope-tied red cloth mantle and the nylon bonding type red cloth mantle cannot be flexibly adjusted, and the supports with different section diameters and different section shapes cannot be fixed firmly and are easy to fall off;

2. the existing red cloth mantle has high labor intensity for arrangement and recovery, low working efficiency and influences the timely development of maintenance work;

3. the existing red cloth mantle is only a piece of red cloth, is easy to drop and not easy to fix, and leads the working site to be uneven and messy;

4. some red cloth curtains need to be arranged on equipment of a net door behind an operating protection screen, and especially for the rope-tied red cloth curtains, fixed points do not exist or the fixation is not firm, so that maintainers can easily touch electrified equipment by mistake, and great potential safety hazards exist;

5. the running character printed on the red cloth mantle used at present is clearer in the daytime, darker in light at night and poor in character definition.
