Abstract
The utility model relates to a temporary grounding wire used for the switching-operation of an electric power line or equipment, belonging to the electric power line or equipment anti-mistake technical field, which comprises a plug, a wire cable and a clamping head. The plug, the wire cable and the clamping head are connected in sequence; when being used, the plug is accessed into a grounding peg fixed on a grounding grid, the clamping head is hung and clipped on the suspension point of the electric power line or the equipment; an identity identification label for presenting the unique identity of the temporary grounding wire is arranged at the position of the plug. Because the identity identification label is arranged at the position of the plug of the utility model, when the temporary grounding wire is arranged by the switching operation and the plug is just inserted in the right position, the identity identification label is read by a reader arranged in the grounding peg, and whether the temporary grounding wire accords with the operating requirements or not is directly or indirectly judged.
Description
Technical field
The utility model relates to power circuit or the anti-error technical field of equipment.Particularly a kind of temporary ground wire that is used for power circuit, equipment grid switching operation.
Background technology
The mistake of current threat power circuit, equipment safety operation behaviour has five classes: mistake is divided, mistake is closed circuit breaker (switch); Mistakenly entering charged chamber; On-load draws, closes isolating switch (disconnecting link); Charged extension (closing) earth connection (ground connection disconnecting link); Band earth connection (ground connection disconnecting link) closes circuit breaker (switch), and back three classes are abominable because of character, consequence is serious, is called pernicious misoperation fault.This wherein just have two roughly the same earth connection use with manage relevant.
As an important kind temporary grounding ray mode in the earth connection pattern of power circuit, equipment, it correctly makes and manages and becomes particularly important.Electrical safe working order is clearly stipulated: every winding ground wire all should be numbered, and leaves the fixed location in.The installing earth connection must connect earth terminal earlier, after connect conductor end, and must contact good.The order that disconnects ground wire in contrast.As seen, the sequence management of the identify label of temporary ground wire and use is extremely important.
Current power circuit or equipment are used for the temporary ground wire of grid switching operation, and what it mainly adopted is the outer adhesive sticker that pastes, and label even oil pen write general modes and next anti-error by the correct and conscious organiztion measures such as operation of educational training operating personnel such as mark.But these measures can not be guaranteed from technical measures: in case get wrong temporary ground wire or installation or remove and use wrong order to mistake, will make follow-up can not carrying out as operation lockings such as maintenance or combined floodgates technically.So the hidden danger that temporary ground wire uses just exists always.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of temporary ground wire that is used for power circuit or equipment grid switching operation is provided, and it can be read identification.
The problem that the utility model need solve is achieved like this:
