Problems solved by technology

[0002] During the transformation and construction process, when the substation cable pay-off vehicle is laying cables, the one-way oil cylinder of the hydraulic device of the existing substation cable pay-off vehicle will have frequent oil leakage during the lifting and falling process of the cable roll, resulting in frequent oil leakage during substation operations. On the other hand, the oil cylinder is not fully returned, and the line cannot be rolled down to the bottom. It is necessary to strengthen monitoring to prevent the line from rolling to the ground unstable and hurting people. The safety risks brought about by this increase accordingly

Abstract

The invention discloses a hydraulic device of a transformer substation cable drum carriage. The hydraulic device of the transformer substation cable drum carriage comprises an oil tank (1), wherein the oil tank (1) is connected with a manual one-way quantitative hydraulic pump (2) through an oil pipe. The hydraulic device of the transformer substation cable drum carriage is characterized in that the manual one-way quantitative hydraulic pump (2) is respectively connected with a pressure release valve (3) and a two-station two-way control valve (4) through oil pipes; the two-station two-way control valve (4) is respectively connected with two current regulating valves (5) through oil pipes; each current regulating valve (5) is connected with an oil cylinder (6) through an oil pipe; the oil cylinder (6) is connected with the oil tank (1) through the two-station two-way control valve (4) and an oil pipe. The hydraulic device of the transformer substation cable drum carriage is simple and practical in structure, a cable can be rolled and lifted safely and reliably, and the safety and the reliability of power supply are ensured.

Description

Technical field: [0001] The invention relates to a hydraulic device for a substation cable pay-off vehicle, which belongs to the field of power system substation operation and maintenance. Background technique: [0002] During the transformation and construction process, when the substation cable pay-off vehicle is laying cables, the one-way oil cylinder of the hydraulic device of the existing substation cable pay-off vehicle will have frequent oil leakage during the lifting and falling process of the cable roll, resulting in frequent oil leakage during substation operations. On the other hand, the oil cylinder is not fully returned, and the line cannot be rolled down to the bottom. It is necessary to strengthen monitoring to prevent the line from rolling to the ground unstable and hurting people. The safety risks brought about by this increase accordingly. Therefore, it is imperative to develop a cable pay-off car hydraulic device that has no oil leakage hidden danger, r...
