Multi-functional coil device integration parameter test device

Abstract

The invention discloses a comprehensive parameter testing device for multifunctional coil equipment, which comprises: a main control board; a program-controlled test power supply module and a measurement unit module respectively connected to the main control board, and a display control part; an isolation transformer whose input terminal is connected to the main control board. The output terminal of the program-controlled test power supply module is connected; the main control board controls the output voltage of the program-controlled test power supply module through the serial port to continuously adjust the sine wave test power supply and control the orderly operation of the measurement unit module; the sine wave test power supply is output through the output terminal of the isolation transformer; The output end of the isolation transformer is provided with a voltage sensor and a current sensor; the measurement unit module calculates the voltage and current signals collected by the voltage sensor and the current sensor in real time and outputs the calculation result; the display control part receives and displays, prints, and stores Calculation results. The invention has the advantages of reducing the number of test equipment, reducing the labor intensity on site, and making the test work more efficient and reliable.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a comprehensive parameter testing device for multifunctional coil equipment. Background technique [0002] Coil equipment (such as various transformers, transformers, etc.) occupies an extremely important position in various equipment in the power system, and its electrical test items are often more and more complicated than other equipment. At present, a set of special test instruments is required for each test of coil equipment in the market, and the test instruments are relatively heavy. Therefore, multiple instruments are often required to complete the test of a device. Restricted by factors such as the site and power supply, it is necessary to repeatedly move the instrument back and forth and repeat the wiring many times in the field work, and the work efficiency is low. [0003] In the prior art, when electrical tests are performed on transformers and power tran...

Problems solved by technology

[0005] At present, the research on comprehensive electrical test devices is still relatively rare at home and abroad. Most of the instruments still have a single function, and the formats of the output results of different manufacturers are not uniform, which also causes a lot of trouble for the later data analysis and filing.
