Description

technical field [0001] The invention relates to a testing device, in particular to a testing device for a die-cut electromechanical cabinet. Background technique [0002] The electric cabinet test refers to testing all the wiring in the electric cabinet. The basic principle is to simulate multiple independent current loops to perform point-to-point sequential output and monitor the state changes of the input terminals. Through this method, the test of the wiring in the electric cabinet is realized. At present, a known test method is to simulate multiple independent current loops, add an electrical appliance (such as an LED light) to each branch, and monitor whether the electrical appliance is working by controlling the status switch at the output end. The way to measure the continuity of the circuit and whether the wiring is correct. But its defect is that this method only simulates the current loop only, and cannot control the circuit board in the electric cabinet, such a...

Problems solved by technology

But its defect is that this method only simulates the current loop only, and cannot control the circuit board in the electric cabinet, such as activating the output of the circuit board, reading the input state of the circuit board, and cannot control the contact action of the contactor. And to identify the phase of the three-phase electricity, so it is not possible to completely test all the wiring in the electric cabinet, which has certain limitations
