Embodiment 1

[0040] Such as figure 1 , 3 , 4, and 5, a management system for the use of temporary grounding wires for power lines or equipment, consisting of a microcomputer error prevention system 1, temporary grounding wires 2, grounding piles 3, a grounding wire bank 4 including fixed piles 40, and hanging points 5 . The microcomputer error prevention system 1 has functions of simulating operation sequences and directly or indirectly accessing, identifying or controlling the fixed stake 40, the ground stake 3, the temporary ground wire 2, and the hanging point 5. For the convenience of those skilled in the art to understand, in the present invention, the applicant illustrates in conjunction with prior art, but is not the restriction to described microcomputer error prevention system 1; For example: 1) described microcomputer error prevention system 1 adopts microcomputer error prevention system 1 Error system host (or claim five anti-error host) plus the control mode of computer key, ...

Embodiment 2

[0055] Such as figure 1 , 6 , 7, the difference between this embodiment and embodiment one is:

[0056] In this embodiment, the temporary grounding wire 2 adopts a one-to-one mode, that is, one of the chucks 23 is respectively connected to the hanging point connected to the power line or the three-phase conduction of the equipment, and the three plugs 21 are respectively connected to the The three ground stakes 3 are correspondingly connected; correspondingly, only one plug coupling coil 25 needs to be set on the plug 21, and only one ground stake coupling coil needs to be set in the ground stake hole slot 32 37. Of course, for the sake of production uniformity, it is also possible to set three ground pile coupling coils 37, but actually two of them will be idle.

[0057] In order to judge whether the plug 21 is mated and fastened with the ground stake hole 32 , the present embodiment adopts the following structure. A sleeve-type movable part 321' and a spring 322' are arra...

Abstract

The invention relates to the anti-misoperation technology field of transmission lines or equipment in the power system, more particularly a management system for temporary ground wires of the power transmission lines or the equipment. The management system comprises a microcomputer-based anti-misoperation system, suspending points, the temporary ground wires, grounding piles and a ground wire tank with fixed piles. The suspending points are connected with conductors of the power transmission lines or the equipment. Plugs, cables and grippers are connected in sequence to form the temporary ground wires. The grounding piles are fixed on the ground net of the power transmission lines or the equipment. The grounding pile comprises a grounding pile locking member, a grounding pile slot and a grounding pile holder. The fixed pile comprises a fixed pile body, a fixed pile slot and a fixed pile holder. The plugs are coupled to the grounding pile slots or the fixed pile slots, and accordingly the grippers are clamped on the suspending points, or idle.

Description

technical field [0001] The invention relates to the technical field of error prevention for power system lines or equipment, in particular to a system and method for managing the use of temporary ground wires for power lines or equipment. Background technique [0002] As we all know, the safe operation of power lines and equipment is becoming more and more important to national production and life. Abnormal power outages, even for a short period of time, will cause huge losses to power production and operation enterprises and users. Among them, people in the industry know that there are five main types of misoperations that threaten the safe operation of power lines and equipment: mis-dividing and mis-closing circuit breakers (switches); mistakenly entering live intervals; pulling and closing isolating switches (knife switches) with load; The live hook (close) grounding wire (grounding knife switch); the belt grounding wire (grounding knife switch) closes the circuit breaker...
