The invention relates to the test equipment of a group control system control cabinet. The equipment comprises a plurality of test circuits under different test processes and a change-over switch. Theplurality of test circuits are connected to the change-over switch. The plurality of test circuits are connected to the tested controller of a control cabinet. The change-over switch is used for switching the test processes of the tested controller. The test circuits are used for carrying out simulation testing corresponding to the test processes on the tested controller according to the test process of the change-over switch lock switching. The test equipment is taken as the simulation equipment of an electric butterfly valve. The tested controller is connected to the test circuit corresponding to the test process of the test equipment. According to the switching state of the change-over switch, the test circuit corresponding to the test process carries out the simulation test corresponding to the test process on the tested controller. Through the test equipment, the control conditions of the tested controller to the electric butterfly valve under various field conditions can be simulated and detected, and test convenience is improved.
