Embodiment 1
[0039] An automatic test system for a phase-change switch-type three-phase load unbalance automatic adjustment device, which is equipped with an industrial computer, program-controlled simulated power grid equipment, an intelligent explosion-proof switch matrix box, a phase-change switch, a program-controlled three-phase load, monitoring equipment and a main control agency.
[0040] Such as figure 1 As shown, the industrial computer is connected to the program-controlled analog grid equipment, intelligent explosion-proof switch matrix box, phase change switch, program-controlled three-phase load and monitoring equipment, one end of the intelligent explosion-proof switch matrix box is connected to the program-controlled analog grid equipment, and the intelligent explosion-proof switch matrix box The other end of the switch is connected to the phase change switch, and the phase change switch is also connected to the program-controlled three-phase load and monitoring equipment re...
Embodiment 2
[0055] An automatic test system for a commutation switch type three-phase load unbalance automatic adjustment device, the other structure is the same as that of Embodiment 1, the difference is that the monitoring equipment includes a temperature inspection instrument and an oscilloscope.
[0056] It should be noted that the temperature inspection instrument is used to monitor the temperature data of the commutation switch in real time, and send the monitored temperature data to the industrial computer. When the monitored temperature data exceeds the set temperature value, the industrial computer will Immediately stop the program-controlled analog grid equipment output.
[0057] It should be noted that an oscilloscope is an instrument used to measure the shape of alternating current or pulsed current waves, and can convert electrical signals into images. In this example. The oscilloscope is used to collect the data of commutation switch commutation time, zero-crossing switchin...
Embodiment 3
[0060] An automatic test system for a phase-change switch-type three-phase load unbalance automatic adjustment device, other structures are the same as those in Embodiment 1 or 2, the difference is that the matrix switch of the intelligent explosion-proof switch matrix box is provided with two or two more than one.
[0061] Set the above matrix switch to 10;
[0062] Such as image 3 As shown, the above-mentioned matrix switches are respectively defined as KM1, KM2, ..., KM10, and the corresponding interface commutation switches are defined as interface 1, interface 2, and interface 3;
[0063] Among them, matrix switches KM1, KM2, and KM3 are three-line incoming or loop switches, matrix switches KM4, KM5, and KM6 are three-line outgoing switches or loop switches, and matrix switches KM7, KM8, KM9, and KM10 are inter-loop contact switches or loops. switch;
[0064] When the above-mentioned matrix switches KM1 and KM2 are closed at the same time, interface 1 is connected to ...
