Abstract

The invention discloses a simulated motor load test device and a test method. The device includes a signal acquisition circuit for collecting the coil voltage of a contactor under test, and is used for controlling the subsequent circuit work according to the signal output control signal input by the signal acquisition circuit. The control system is used to simulate the load circuit of AC and DC motor loads, and the control circuit used to control the working state of the contactor coil under test. The device provided by the invention simulates a motor and can be used as a load of a tested contactor without purchasing a motor, thereby reducing enterprise costs. In addition, the device provided by the present application can also be simulated as different types of motors according to actual conditions, so as to meet different types of contactor tests.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for simulating the load of an AC and DC motor to test whether the tested contactor is working normally. [0002] Secondly, the present invention also relates to a test method, in particular to a test method for simulating motor load. Background technique [0003] A contactor is a device that can quickly cut off the AC or DC main circuit and can frequently connect to a large current control (some types can reach 800 amperes) circuits. The motor is one of its most operating control objects. In addition, the contactor can also be used to control electrical loads such as factory equipment, electric heaters, working machines and various electric power units. The contactor can not only connect and cut off the circuit, but also has the function of low-voltage release protection. The contactor has a large control capacity and is suitable for frequent operation and remote control. It is one...
