Abstract

The invention discloses a control cabinet inspection method and device for a cold water machine room group control system. The device comprises a unit loop test module, a motor loop test module, an electric butterfly gate loop test module, an analog quantity test module, and a communication test module. According to the invention, with the inspection device having the existing water system equipment function, running conditions of the water system equipment under control of the controller under various working conditions are simulated; the test result is convenient to observe; and the test cost of the control cabinet is lowered.

Description

technical field [0001] The invention relates to the field of unit technology, in particular to a method and device for inspecting a control cabinet of a chiller room group control system. Background technique [0002] At present, the inspection methods for the control cabinets used in the chiller room group control system in the industry are mainly divided into two parts. One is the insulation withstand voltage, electrical clearance, creepage distance, EMC electromagnetic compatibility, and strong current discharge for electrical safety. The second is the inspection and correction of the wiring, wiring and routing of the electrical control lines inside the control cabinet. The inspection industry for electrical safety is very mature, but for the inspection and correction of the wiring and wiring of the electrical control lines inside the control cabinet, most of the industry still stays in the traditional methods of comparing drawings and manual calibration. The inspections...
