Manual and automatic integrated wire calibrating system and method of electrical equipment

Abstract

The invention relates to a manual and automatic integrated wire calibrating system and method of electrical equipment. Wire calibration is conducted by combining light, current and resistance as wellas information technologies, so that accuracy degree and credibility of wire calibration are improved, on-site use is facilitated, heavy wire calibration and cost burdens are reduced for workers, andfoundation is laid for zero-defect commissioning of the subsequent electrical equipment. The system comprises a first wire calibration module and a second wire calibration module which are the same; the positive or negative polarity output port of the first wire calibration module is connected to a to-be-calibrated wire on the same side of the electrical equipment; the rest other polarity output port of the first wire calibration module is connected with a ground wire; the second wire calibration module selects the opposite polarity output port connected with the first wire calibration moduleand the to-be-calibrated wire to be connected to the opposite side of the to-be-calibrated wire of the electrical equipment; the rest other polarity output port of the second wire calibration module is connected with the ground wire; the first wire calibration module and the second wire calibration module perform instruction and signal transmission as well as information sharing through the own wireless transmission modules and crossly judge the correctness and the integrity of the to-be-calibrated wire of the electrical equipment.

Description

technical field [0001] The invention belongs to the technical field of electrical primary and secondary equipment maintenance, transformation and debugging, and in particular relates to a manual-automatic integrated calibration system and method for electrical equipment. Background technique [0002] Electrical primary and secondary equipment is an important part of each link of power generation, transmission, transformation, and distribution. Whether the circuit connection is correct and perfect directly affects the safe and stable operation of the power system. In order to maintain the electrical primary and secondary equipment in service in the best condition, it is necessary to eliminate defects and debug during the various periods of infrastructure construction, maintenance, and transformation. As the most basic work, the calibration line directly affects the accuracy of the electrical primary and secondary equipment. Whether the equipment can be safely put into operati...

AI Technical Summary

Problems solved by technology

[0007] 1) The efficiency of the calibration line is low: at least two people are required to complete the calibration line, and at the same time, it is equipped with voice communication equipment. At present, the intelligent integrated electrical secondary equipment contains a large number of external wires, and it takes a lot of time to calibrate the external wires of the entire electrical equipment. Indirect increase in labor and equipment costs

[0008] 2) There are hidden dangers in the calibration line: the manual calibration line is susceptible to interference from the external environment and the staff themselves, including random factors such as poor communication and inattention of the staff, resulting in individual hidden dangers after the calibration of electrical equipment. Operational impact

[0009] 3) The calibration method is single: no matter whether the multimeter or the light is used to calibrate the line, only a single intuitive sound or light method is used to judge the line to be calibrated, and the two methods are not organically combined to further confirm the calibration situation

[0010] In addition, so far, there has been no report on the finished device and related application of a similar electrical equipment manual-automatic integrated calibration system on the market.
