This paper introduces several common shortcomings of work gloves in electric energy measurement, and focuses on the disadvantages of the spandex gloves; it expounds the method and technique principle of multifunctional gloves for electrical work and introduces the main parameters and field application effect of the gloves. Therefore, it is concluded that the multifunctional glove for electrical work not only solve the security problems, but also saves time and effort, greatly improving the work efficiency, and can strengthen the quality and quantity of the calibration task for the company.
In order to solve the existing high voltage switch gear when the voltage difference method using core phase, due to the different switch gear supporting capacitive sensor indicators are inconsistent, resulting in phase sequence check misjudgment and other issues, this paper uses the phase difference between the two high voltage switch gear method of phase sequence check, this method has the versatility to determine the exact characteristics such as the actual test to fully meet the requirements of high voltage switch gear core phase.
Abstract. In order to solve the problem of GIS equipment structure and limited space, the paper develops the fixed device for rotary ultrasonic sensor based on the actual situation, expounds the principle of ultrasonic testing, and introduced the partial discharge defects, corona defects, free metal particle defects can be found by testing ultrasonic partial discharge test. It discusses that the device can effectively solve the problems of the prior test GIS ultrasonic partial discharge, and ensure the safety of the test personnel.
The infrared leak detection technology of SF6 equipment can detect and locate the gas leakage without power failure, and realize the real-time transmission of fault image, improve the efficiency of maintenance, ensure the safe and stable operation of SF6 electrical equipment. In this paper, the problem of SF6 gas leakage in Benxi Hedi 220kV substation and Liaoyang Shoushan 66kV substation is discussed. The infrared leak detection technology of SF6 equipment is studied and analyzed. This paper discusses the harm, advantage, principle and field application of infrared leak detection technology. According to different leakage reasons, the relative solutions are summarized.
This article illustrates the characteristics and proportion of GIS system failure through the introduction to GIS system structure and characteristics; In order to make the GIS in the safe operation of the power system, It is necessary to test AC withstand voltage at the scene.
