Problems solved by technology

[0002] At present, the operation of substation equipment requires operators to go to the site to confirm or make judgments based on the information provided by the video system. Substation inspections also require operators to go to the site to collect relevant equipment information. Remote inspection and inspection of substations cannot be realized. As the scale of substations continues to Expansion, substation operation and inspection will consume a lot of manpower and material resources, causing staff tension

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] refer to Figure 1-2 , a grating displacement sensor system for detecting the position status of a switch in a substation, a grating displacement sensor and a background operation and maintenance system;

[0020] The grating displacement sensor collects the angular displacement change signal of the switch in the substation, and transmits it back to the background operation and maintenance system; the background operation and maintenance system compares the received angular displacement change signal with the preset maximum closing angle in the system Compare with the minimum closing angle; if the angular displacement change signal is greater than the minimum closing angle and smaller than the maximum closing angle, it is judged that the knife switch is closed. The maximum closing angle and the minimum closing angle are recorded by the s...

Abstract

The invention provides a pattern displacement sensor system for detecting the position state of a disconnecting link of a transformer substation. The system comprises a pattern displacement sensor and a background operation and maintenance system. The pattern displacement sensor is used for collecting angular displacement change signals of the disconnecting link of the transformer substation and transmitting the signals back to the background operation and maintenance system. The background operation and maintenance system compares the received angular displacement change signals with the maximum link closing angle and the minimum link closing angle which are preset in the system, and if the angular displacement change signals are larger than the minimum link closing angle and smaller than the maximum link closing angle, it is judged that the disconnecting link is closed. According to the pattern displacement sensor system for detecting the position state of the disconnecting link of the transformer substation, the position state of the disconnecting link of the transformer substation is automatically detected, the disconnecting link of the transformer substation is remotely patrolled and checked, and a large amount of labor and vigor are saved.

Description

technical field [0001] The invention relates to an optical fiber displacement sensor system, in particular to a grating displacement sensor system for detecting the position state of a switch of a substation. Background technique [0002] At present, the operation of substation equipment requires operators to go to the site to confirm or make judgments based on the information provided by the video system. Substation inspections also require operators to go to the site to collect relevant equipment information. Remote inspection and inspection of substations cannot be realized. As the scale of substations continues to Expansion, substation operation and inspection will consume a lot of manpower and material resources, causing personnel tension. Therefore, combined with sensor technology, it is very promising to carry out research and application of remote monitoring and automatic inspection of substation equipment remote monitoring and inspection. Mechanical failure, so as ...
