Knowledge of diesel Guangzhou generator
广州发电机 安全运用留意关键 The key to the safe use of diesel generators in Guangzhou It is necessary for diesel Guangzhou generating units to be operated by personnel who understand the structure of the unit and master the safe operating procedures. New or newly overhauled diesel units are required to run in for 60 hours in accordance with regulations and be properly maintained. Regarding new or long unused generators, it is necessary to undergo rigorous inspection before putting them into normal work. First, check the winding insulation and wiring conditions, and if necessary, take necessary measures. After the diesel engine is started, the speed should be gradually increased. Under the premise of inspection and acceptance, all no-load work can be performed from low speed to extra speed. When working at no load, focus on checking the oil pressure, whether there are abnormal sounds, excitation current, three-phase voltage changes, etc., if there are abnormal conditions-stop inspection immediately. After finding out the situation, start again. If everything is normal, you can put it into normal work. The operator should closely monitor the changes of the instruments on the control screen, whether they are planning, and make corresponding adjustments. During operation, the operator should keep a safe distance from live equipment and wear labor protection equipment. Please pay attention to the sequence of the switching operation. If there is a power failure, first switch off each branch switch, then switch off the main switch, and then switch the position of the four-pole double-throw knife switch. When transmitting power, the order is reversed. Normal shutdown should first unload part of the load, then turn off the main switch, and finally turn off the diesel engine. It is not allowed to not turn off the main switch, and power off as the diesel engine goes out. After the shutdown, make a routine inspection of the unit and record the work (operation diary). If someone gets an electric shock, you should sensitively block the power switch, or use an insulation appliance to sensitively disconnect or disconnect the power source. Then rescue, and ask the doctor to come to the scene to rescue. If there is a flood of electrical equipment, the relevant power supply should be blocked immediately, and the local power supply station should be reported, and then fire fighting should be carried out. For fire-fighting equipment, dry-type life-saving devices, carbon dioxide life-saving devices, etc. should be used, and water must not be used. Diesel Guangzhou generator set equipment pay attention to the key 1. The surroundings of the equipment ground should be kept clean to avoid placing nearby items that can cause corrosive gases such as acid and alkali. Conditions should be equipped with rescue equipment. 2. The equipment location should be well ventilated, the generator side should have a satisfactory air inlet, and the diesel engine side should have an excellent air outlet. The area of the air outlet should be more than 1.5 times the area of the water tank. 3. It is necessary for the two-way switch of the generator and the city power to be very reliable to prevent reverse power transmission. The wiring reliability of the two-way switch must be checked and approved by the local power supply department. 4. For indoor use, it is necessary to lead the exhaust pipe to the outside, and the pipe diameter must be ≥ the diameter of the smoke pipe of the muffler. The elbow of the connected pipe should not exceed 3, in order to ensure smooth smoke exhaust, Tilt the pipe downward 5-10 degrees to avoid rainwater injection; if the exhaust pipe is vertically upwards, it is necessary to install a rain cover. 5. When concrete is used for the foundation, the level must be measured with a spirit level when the equipment is used, so that the unit is fixed on the horizontal foundation. There should be special shock pads or foot bolts between the unit and the base. 6. The unit housing must have reliable protective grounding. For generators that require a neutral point to be directly grounded, it is necessary to have a professional grounded neutral and equipped with lightning protection equipment. It is strictly forbidden to use the grounding equipment of the city power supply. The ground point is directly grounded.
