Substation ground grid grounding measurement line wiring and take-up process, take-up and release car

Abstract

The invention provides a technology for arranging and taking up a grounding measurement wire of a transformer substation grounding grid. The technology for arranging and taking up the grounding measurement wire of the transformer substation grounding grid comprises the following steps of determining the length of the current electrode and the length of the potential electrode according to the length of a diagonal of the grounding grid and the preset electrode arrangement method, determining the position of the current electrode and the position of the potential electrode, enabling a ground stud of the current electrode and a ground stud of the potential electrode to be earthed, leading out the measurement wire through a pay-off and take-up barrow and arranging the wire in the outward direction on the edge of the ground grid before ground resistance measurement of the ground grid, enabling the measurement wire of the pay-off and take-up barrow which is provided with a wire coil with the measurement wire coiled to be respectively connected with the ground stud of the current electrode and the ground stud of the potential electrode through test pincers, and taking up the wire through coiling the wire coil of the pay-off and take-up barrow in the inward direction on the edge of the grounding grid after the ground resistance measurement of the ground grid is finished. The invention further provides the pay-off and take-up barrow. The technology for arranging and taking up the grounding measurement wire of the transformer substation grounding grid and the pay-off and take-up barrow shorten the pay-off and take-up time, and therefore the efficiency of resistance measurement is improved.

Description

technical field [0001] The invention relates to the field of line wiring and take-up technology, in particular to the wiring and take-up technology of substation ground network grounding measurement lines, and a take-up and release vehicle. Background technique [0002] The substation ground grid is an important parameter to measure the effectiveness and safety of the grounding system. Before the substation is put into operation, the ground grid test should be carried out. After the substation is put into operation or when necessary, the ground grid resistance of the substation should also be checked regularly. [0003] At present, the three-pole method is a widely used test method for grounding resistance testing of large substation grounding grids at home and abroad. Wiring is required before measuring resistance, and wires need to be taken up after measuring resistance. Conventional substation grounding measurement line wiring and take-up process is the method of manually...
