Overhaul watch board of 35kV double-bus double-section wiring structure

Abstract

The invention discloses an overhaul watch board of a 35kV double-bus double-section wiring structure. The 35kV double-bus double-section wiring structure comprises a section I bus, a section II bus, asection III bus and a section IV bus, wherein a section I and III isolation cabinet and a section I and III switch cabinet are connected between the section I bus and the section III bus; a section II and IV isolation cabinet and a section II and IV switch cabinet are connected between the section II bus and the section IV bus; the section I and III isolation cabinet and the section I and III switch cabinet are positioned at one side of a vestibule; the section II and IV isolation cabinet and the section II and IV switch cabinet are positioned on the other side of the vestibule; and a circuitdiagram of the 35kV double-bus double-section wiring structure is shown on the overhaul watch board. The overhaul watch board has the advantages that the wiring structure of the system in the regioncan be clearly shown, so that overhaul and operation personnel can comprehensively master the wiring condition in the position, and know the charged dangerous source point positions and safety measurearrangement conditions; the operation and overhaul operation risk is reduced; the overhaul safety is improved; and the overhaul operation safety is ensured.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment maintenance, in particular to a maintenance kanban with a 35kV double-busbar double-section wiring structure. Background technique [0002] The structure of the 35kV dual-bus dual-section power supply system is complex, and the safety risks of switching operations and maintenance operations are high. In particular, the wiring structure of the 35kV double-busbar double-section switchgear and its isolation cabinet area is complex. Assume that when the equipment of the 35kVI section I and II busbar system is overhauled, the equipment of the 35kVI section I and II busbar system is powered off, but some equipment in the 35kVI section switchgear located in the area of ​​the 35kVI section I and II busbar system is electrified and cannot be repaired. In the 35kVIII and IV section busbar system area, the 35kVII and IV subsection isolation cabinets need to be overhauled (when the 35kVIII and...

AI Technical Summary

Problems solved by technology

[0002] The structure of the 35kV double-bus double-section power supply system is complex, and the safety risks of switching operations and maintenance operations are high

In addition, the four-section busbars are all fully enclosed structures, the switching operation and safety measures are complicated, and the maintenance equipment and live running equipment are intersected, so the risk of maintenance operations is very high

Under normal circumstances, the maintenance and cleaning operations here need to be supervised by special personnel
