Abstract

The invention discloses a portable fault detecting device and method for a high voltage shunt reactor, and the device comprises a main control module and further comprises a thermal imaging module, avibration collecting module, a display module, a storage module and a power module which are electrically connected to the main control module, wherein the thermal imaging module is configured to collect surface temperature information of the reactor and send the information to the main control module; the vibration collecting module is configured to collect a vibration signal of the reactor and send the signal to the main control module for processing; and the main control module is configured to process the temperature information and the vibration signal and judge whether the reactor is abnormal or not. The portable fault detecting device provided by the invention is light and portable, and can realize the detection of problems such as abnormal vibration, looseness of awinding and acore, and local overheating of the high voltage shunt reactor. The diagnosis method uses the ratio of the amplitude of the frequency components of 200Hz and 100Hz as a principal component coefficient, andincludes measurement factors of vibration characteristics to improve the accuracy of the vibration test. The method is applicable to different types of reactors, and has high accuracy, low hardware requirements and good practicability.

Description

technical field [0001] The invention relates to a device for detecting faults of high-voltage electrical equipment, in particular to a portable fault detection device and method for high-voltage shunt reactors. Background technique [0002] With the development of the economy and the improvement of people's living standards, the scale of the power grid continues to expand, and the load on the power grid continues to increase. In order to enhance reactive power compensation and reactive power balance in the power system, suppress system overvoltage, improve power quality and power supply reliability, high-voltage parallel connection Reactors are widely used. There have been many reactor failures in UHV and EHV power transmission and transformation projects that have been put into operation, so it is necessary to pay enough attention. Due to structural reasons, existing high-voltage shunt reactors will inevitably vibrate during operation. Long-term operation will easily lead ...
