Inspection and maintenance of diesel generator electronic control system
Diesel generatorsThe electrical control system of the generator is mainly composed of important equipment such as electrical control cabinets, excitation cabinets, synchronization cabinets and UPS cabinets. With the support of relevant advanced equipment and technology, the electrical control system of the generator has parameter detection, status control, unit starting, Information display and automatic protection functions. During the operation of the electronic control system, the diesel engine control cabinet will automatically start the diesel engine and detect and evaluate various parameters of the diesel engine. When it is detected that the operating data or effects deviate from the predetermined plan, the equipment An early warning message will be automatically issued and protective measures will be taken to prevent damage to the diesel engine. The 220VAC power supply required for the diesel engine control cabinet is mainly provided by the UPS cabinet. Based on the above structural characteristics, when performing maintenance on the electrical control cabinet, staff should follow the following procedures Operate according to standard procedures:
First, when overhauling the electric control cabinet, key checks should be made on the connection status of the power cord of the electric control cabinet, the wiring of the connecting wires, the wiring of the control cabinet, etc., to ensure that the power supply wiring is accurate, the grounding wire is consistent and reliable, and the control cabinet wiring is scientific Correct. Maintenance personnel need to detect the steering conditions of each pump in the auxiliary system, detect the actual temperature of the high-temperature cooling water on the display screen of the diesel generator control cabinet, and detect the protective actions of the electric control cabinet to ensure that the diesel power generation Functions are effectively protected.
2. When maintaining the diesel generator electric control cabinet, the following maintenance plan should be formulated: 1. Do daily maintenance work, mainly including wiring inspection, tightening the loose wiring with a screwdriver; fuse inspection, If any fuse is burned, replace it with a new one in time; check and handle the wiring. For the fallen wiring, connect it accurately in strict accordance with the drawing. 2. Carry out some preventive maintenance work regularly, such as regularly checking the terminals of the diesel generator Check whether the wiring terminals and components in the cabinet are loose, and whether the components are firmly installed.
