Abstract

The invention provides a displacement sensor error detection method for high-voltage switch equipment. The method comprises the steps as follows: (S1) a host computer sets a rotary motion curve of a motion process of an analogue high-voltage switch contact, converts the rotary motion curve into a control parameter of a servo motor drive controller and transmits the control parameter to the servo motor drive controller; and a servo motor is driven to rotate; (S2) the servo motor drive controller compares the rotary motion curve set by the host computer with an actual rotary motion curve of the servo motor and adjusts output of the servo motor drive controller, so that the actual rotary motion curve of the servo motor is consistent with the rotary motion curve set by the host computer; and (S3) the host computer analyzes, calculates and displays the rotary motion curves, measured by a standard displacement sensor and a detected displacement sensor, of the servo motor, calculates the error of the standard displacement sensor. According to the method, adaptability and accuracy detection of the detected displacement sensor can be quickly, simply and conveniently finished; and the detection time and cost are greatly reduced.

Description

technical field [0001] The invention relates to an error detection method, in particular to a displacement sensor error detection method for high-voltage switchgear. Background technique [0002] The contact position and motion parameters of high-voltage switches are directly related to its electrical performance, so manufacturers and users pay more and more attention to this. With the development of smart grid technology, accurate and reliable monitoring of the mechanical state of high-voltage switches is an important means to ensure the normal operation of high-voltage switches. At present, in the method of monitoring the mechanical state of the high-voltage switch, it is more commonly used to install a related linear displacement sensor on the moving contact transmission rod of the high-voltage switch or to install a rotary displacement sensor on the transmission shaft of the moving contact. [0003] The accurate measurement of the displacement sensor is an important pre...
