Problems solved by technology

At present, the voltage stabilization measures of various test benches are to take the average value of the voltage of each phase of the three-phase power supply as the sampling reference voltage, that is, to use a three-phase system-adjusted voltage stabilizer. Due to the imbalance of the three-phase voltage, there is an obvious oscillation phenomenon. It is bound to affect the accuracy of detection

Abstract

The invention discloses an explosion-proof electric apparatus performance test board which is formed in the following way: a three-phase separately-adjustable voltage regulator is connected with input ports of a three-phase electrical parameter measurement module, a voltage current input module, a single-phase electrical parameter measurement module and a temperature acquisition module by a Delphi communication interface; a solid-state relay is connected with the input ports of a digital input-output module, a frequency and pulse counting module and a relay input-output module; data ports of all the modules are connected with a data port of an RS485 bus module, the RS485 bus module is connected with a PLC (programmable logic controller) industrial personal computer, and the three-phase separately-adjustable voltage regulator is controlled by voltage-regulating software of the PLC industrial personal computer. The explosion-proof electric apparatus performance test board has an overall parameter measurement function such as device temperature rise and the like and can improve the detection accuracy of all parameters of the electric apparatus.

Description

technical field [0001] The invention relates to the technical field of mine electrical equipment testing, in particular to an explosion-proof electrical performance testing platform. Background technique [0002] The electrical appliances used in coal mines are all explosion-proof electrical appliances, such as electromagnetic starters, auto-coupling decompression starters, feed switches, explosion-proof buzzers, coal electric drills, etc. Due to the harsh working environment of coal mines, large temperature difference and humidity, electrical faults such as leakage and short circuit often occur, which can easily cause coal mine gas explosions, so the protection performance of explosion-proof electrical appliances should be checked regularly. [0003] At present, the detection content of the explosion-proof electrical test bench includes parameters such as short circuit, overload, undervoltage, leakage resistance, leakage blocking, and capacitance compensation. As we al...
