Novel electric power detection device and method

Abstract

The invention relates to the technical field of power detection equipment, in particular to a novel power detection device and method.The novel power detection device comprises a shell, and an experiment groove is formed in the middle of the upper surface of the shell; two supporting columns are symmetrically mounted on the two sides of the bottom in the experimental tank, and the upper ends of the supporting columns are fixedly connected with electrode columns; a measuring oil cup is arranged in the middle of the bottom in the experiment groove; the positions, penetrating through the side wall of the measuring oil cup and connected with the measuring oil cup, of the two electrode columns are each provided with a sealing turnover mechanism used for facilitating turnover of the measuring oil cup, and meanwhile sealing connection between the measuring oil cup and the electrode columns can be guaranteed. According to the invention, dust can be prevented from falling into the measuring oil cup, and as the measuring oil cup is inverted, humid water vapor is not easy to attach to the inner wall of the measuring oil cup and the electrode column, so that the possibility of inaccurate test data caused by the influence of impurities or water vapor when an insulating oil sample enters the measuring oil cup is reduced; and meanwhile, the sealing performance between the measuring oil cup and the electrode column can be ensured during an experiment.

Description

technical field [0001] The present invention relates to the technical field of electric power detection equipment, in particular to a novel electric power detection device and method. Background technique [0002] Power testing equipment refers to the equipment for testing, verification, inspection and acceptance of power production and power grid operation, which provides a strong guarantee for the safety and reliability of power operation. [0003] Commonly used are: insulation withstand voltage test equipment, transformer test equipment (such as gas relay calibrator), electric energy meter verification device (such as three-phase electric energy meter field calibrator), transformer measurement monitoring and testing equipment, grounding device testing equipment, Relay protection test equipment, etc. [0004] Insulating oil is the most commonly used working medium for electrical equipment, and the withstand voltage test equipment for insulating oil is also common. , and ...

Problems solved by technology

[0007] However, although the above-mentioned patents have reduced the influence of dust and water vapor to a certain extent, there are still many deficiencies: first, the device only considers the cleaning and protection before oil entry, but after the end of the pressure test, it needs to When cleaning the measuring oil cup, it is necessary to disassemble the plugging cover and the entire hot air circulation mechanism to clean it, which makes it difficult to clean up in the later stage of the test. Carry out inflation and deflation operations to achieve the effect of scraping off the oil or impurities attached to the side wall of the electrode column during the process of being wrapped by the friction removal bag, although it has played a role in cleaning the side wall of the electrode column , but after the inside of the measuring oil cup is filled with oil, the oil will submerge the electrode column and the friction-removing bag wrapped around it, and the impurities that have been scraped off and stuck to the friction-removing bag will still be incorporated into the oil , which in turn affects the test accuracy. Finally, the overall structure of the device is relatively complicated, which will increase the manufacturing cost of the detection device and also bring difficulties to the test operation.
