Problems solved by technology

The subsidence of the foundation will cause the support frame or transmission line tower of electrical equipment such as circuit breakers and isolating switches in the substation to tilt. When the support frame or transmission line tower tilts slightly, the monitoring should be strengthened; When the level is too high, it will lead to serious consequences such as poor electrical connection or broken wires due to tilting of the tower, threatening the safe and stable operation of power equipment.
The monitoring of the prior art realizes the monitoring of the foundation settlement by periodically measuring the change of the altitude of the foundation settlement monitoring point by the operation and maintenance personnel; this monitoring method has different effects on the inclination degree of a specific support frame or transmission line tower. Able to make accurate judgments, but does not have the function of real-time monitoring

Abstract

The invention discloses an on-line monitoring device for inclination of a disconnecting switch supporting frame, and solves the difficulty in on-line real-time monitoring of the inclination of the disconnecting switch supporting frame. A gap (3) which is shaped like half a Chinese character KOU is formed in the center of the inner side of a semicircular supporting base plate (2); monomer hydraulic supporting columns (4) and a horizontal tray (5) are fixedly arranged on the top surface of the semicircular supporting base plate (2); a semicylindrical barrel body (6) is fixedly arranged on the horizontal tray; a liquid capacitor is arranged in the semicylindrical barrel body (6); a pressure measurement device is arranged on the vertical surface of a triangular-prism-shaped slot (7); a disconnecting switch supporting frame vertical column (1) is arranged in the gap (3) formed in the center of the inner side of the semicircular supporting base plate (2); the inner side surface of a contact pin swing rod (15) presses against the side surface of the disconnecting switch supporting frame vertical column (1). The on-line monitoring device is simple in structure and convenient for on-site combination, so that the aim of measuring the inclination of the disconnecting switch supporting frame immediately and accurately is achieved.

Description

technical field [0001] The invention relates to an on-line monitoring device, in particular to an on-line monitoring device for the inclination of a disconnector support frame. Background technique [0002] In the operation and maintenance of substations and transmission line towers, the problem of foundation settlement is often encountered. The subsidence of the foundation will cause the support frame or transmission line tower of electrical equipment such as circuit breakers and isolating switches in the substation to tilt. When the support frame or transmission line tower tilts slightly, the monitoring should be strengthened; To a certain extent, it will lead to serious consequences such as poor electrical connection or broken wires due to tilting of the tower, threatening the safe and stable operation of power equipment. The monitoring of the prior art realizes the monitoring of the foundation settlement by regularly measuring the change of the altitude of the foundatio...
