Cause analysis of air compressor tripping as soon as it is started

(1) Firstly, it is necessary to determine whether tripping refers to the bounce of the overload protector or the tripping of the air switch in the power supply circuit.
(2) If it is an air switch that jumps, first determine the size of the air switch and determine whether it can withstand the load of the machine. The conversion is as follows: For a 20A air switch, the machine power is 6KW, and 6000W/220V=27A. The selected air switch is too small, so it needs to be replaced with a larger air switch.
(3) If the specifications of the air switch are sufficient, there may be a short circuit in the wiring inside the machine. It is necessary to check the wiring of the machine to determine whether there is a short circuit.
(4) Another possibility is that the machine is leaking electricity. Currently, some air switches on the market are equipped with leakage protection switches. If the insulation layer of the live parts on the machine is damaged, it will lead to a large leakage current. Once the ground leakage current is greater than 30 MA, the air switch will jump off. If this is the case, it is necessary to use professional equipment to detect which electrical components fail to withstand voltage, or replace them one by one to check and confirm.
