Problems solved by technology

[0002] Substations need to be repaired and constructed every year, but some substations have a special operation mode, which is the operation mode of "single busbar segmented and double arrangement". When the construction range is very close to the electrified distance, the risk factor is large, and there are many construction safety risks, so it brings great difficulties to the construction

Embodiment 1

[0025] On-site survey: Combined with the power outage sequence of the substation, for example, when the substation section I is powered off and the branch bus is replaced, investigate the intersection of the branch bus bar of section I and the live bus bar of section II, the height of the branch bus bar of section I and the live bus bar of section II, And the height difference at the intersection of the busbars of sections I and II; investigate the intersection width, intersection angle and terrain.

[0026] 1. Set up the insulation spanning bracket:

[0027] 1) The insulation crossing bracket is made of insulating material. The height of the shelf is 7.5 meters based on the height of the switchyard door frame. The top of the shelf is equipped with a chute 4 made of insulating material with a height of 300mm and a width of 400mm. All assembly parts are connected by bolts, and the height of the shelf can be adjusted, and the on-site assembly is flexible and convenient.

Abstract

The invention discloses a construction method for exchanging the bus of an electric power substation with the single bus arranged in double rows. The method comprises the following steps: 1, building an isolated spanning bracket; 2, dismounting a lead; 3, mounting the bus; 4, dismounting an isolated frame. The method is suitable for the operation of exchanging the buses of the switch yard of the electric power substation 'with the single bus arranged in double rows', saves the manpower and material resources during the project construction, shortens the project period and reduces the project construction risks; moreover, the manufactured construction device has the advantages of flexible application, convenient dismounting and repeated use, thus saving the cost.

Description

Technical field: [0001] The invention relates to a method for replacing busbars in the field of oil field electric power construction, in particular to a construction method for replacing busbars in substations with single busbars segmented and arranged in double rows. Background technique: [0002] Substations need to be repaired and constructed every year, but some substations have a special operation mode, which is the operation mode of "single busbar segmented and double arrangement". When the construction range is very close to the electrified distance, the risk factor is large, and there are many construction safety risks, so it brings great difficulties to the construction. Invention content: [0003] In order to overcome the deficiencies in the background technology, the present invention provides a substation bus replacement construction method with single-bus section double-arrangement arrangement. , save manpower and material resources in engineering constructi...
