The calibration system comprises a laser measurement sampling device, a mathematical modeling system and an expert analysis decision system, wherein the mathematical modeling system and the analysis system are installed in a debugging computer;the laser measurement sampling device collects various position parameters of a target isolation switch in a space coordinate system; the mathematical modeling system establishes a mathematical modelof the isolation switch space by using the position parameters collected by the laser sampling device; and the expert analysis decision system compares the actual mathematical model of the isolationswitch to be debugged with a standard spatial position model of the isolation switch stored in a database and gives an error and calibration scheme. Compared with the prior art, the ultra-high voltageisolation switch intelligent debugging and calibration system has the following advantages: the debugging process is completed in one step, the work efficiency is improved, and the debugging accuracyis improved.

Description

technical field [0001] The invention relates to the field of isolating switch debugging, in particular to an intelligent debugging and calibrating system for ultra-high voltage isolating switches based on laser measurement technology. Background technique [0002] With the development of our country's economy, the national power construction is also developing continuously, the power grid is constantly expanding, the capacity is constantly improving, and the number of substations is constantly increasing. Isolating switch is the most widely used type of high-voltage power transmission and transformation equipment, and its usage is also increasing accordingly. The investment period of equipment is increasing, a large number of isolating switches are facing the situation of dismantling and overhauling, and the workload of maintenance is constantly increasing. [0003] During the operation of the isolating switch, it is subjected to mechanical stress and thermal stress for a l...

AI Technical Summary

Problems solved by technology

[0003] During the operation of the isolating switch, it is subjected to mechanical stress and thermal stress for a long time, which causes the transmission mechanism to wear and deform, resulting in faults such as the opening and closing of the isolating switch is not in place, and the three phases are out of phase. Therefore, it is necessary to check the position of the switch knife during maintenance. Adjustment

[0004] The traditional disconnector debugging method is relatively backward, and requires power-off measurement. Traditional tools such as tape measure, level ruler and plumb are widely used. The error range is large, the time required is long, and the requirements for personnel experience are high.

At present, there is no relevant research on intelligent debugging methods of isolating switches at home and abroad
