Description

Small-sized idle opening and error closing prevention card hanging device

Technical Field

The utility model relates to the field of power plant overhaul, in particular to a small-sized idle opening anti-misoperation closing card hanging device.

Background

A large number of small-sized air switches are installed in an electric control panel cabinet of a power plant (transformer substation), and when loads corresponding to the switches need to be overhauled, safety measures need to be implemented: the switches are disconnected, and a 'forbidden closing, a person works' sign board is hung on an operation handle of the switches, so that the power is sent to a maintenance site by the false closing, and safety threat is caused to operators or equipment.

However, the "forbidden closing, someone" sign usually uses the rope to hang, because the operating handle of the small air switch is generally smaller, the rope of the sign has no force point, can only be hung by the tiny bulge on the surface of the operating handle, so the hung sign is very easy to drop (drop when touching) and causes the failure of the safety measures, which is not allowed by the electric industry safety working regulations; moreover, these small air switches are typically installed compactly in rows, there is little space between the operating handles of adjacent small air, resulting in a high likelihood of mishandling the adjacent small air switch when operating a certain switch, which can adversely affect the operating electrical equipment, which is also not permitted to occur by electrical power production.

The small-sized idle opening is generally provided with a closing prevention jack on the lug structure at two sides of the shifting handle, but the jack is small, if a transverse thin bolt is adopted, the small-sized idle opening is difficult to insert and pull, and the idle opening in the middle is difficult to operate the bolt.

In summary, it is necessary to optimize and improve the conventional signboards, so as to ensure reliable and effective field safety measures and prevent personal injury and misoperation.
