Check the DC operating voltage generators fell 80% Un, the Generator switch and circuit protection should be reliable and correct action. Check the generator circuit host operating correctly and reliably start and stop. Pre-commissioning test generator generator step-up from zero to 1.3 times the rated voltage withstand test induction generator, the generator voltage read point by point with the excitation voltage, generator voltage draw with excitation voltage characteristic curve. Generator switch three-phase short DSE7320, overcurrent protection inputs, smooth adjustment to the rated output current of the generator, the generator output current read point by point with excitation voltage, current draw and generator excitation voltage curve. Generator switch off the generator relay all put DSE5120, generator step-up to the rated load voltage, the output voltage of the generator at bus and sides with nuclear tests. Qualifying matches generator output voltage phase sequence identity with the bus. When the generator manually start an indoor temperature is below 20 ℃, the electric heater is turned on, the machine to warm up. 2, check the diesel generators around the presence of the body and hinder the operation of the debris, if any should be removed. 3. Check the crankcase oil level, fuel tank oil level, radiator water level. If the oil level is below the specified level value should be added to the normal position. 4. Check the fuel supply valve diesel generators and cooling water shut-off valve is in the open position. 5, check the starter battery electric voltage is normal. 6, testing and distribution of diesel generator sets screen test button, observe the warning light has turned shiny. 7. Inspect the electrical panel switch is placed in the OFF position, indicate whether the instrument is in the zero position. 8, start diesel generator sets inlet and exhaust fan. 9, press the engine start button DSE7110, it starts running. As the first starter to fail, you can press the reset button corresponding distribution panel DSE, let it alarm eliminate diesel generator set back to normal state before the second start. After starting the machine running sound normal, the cooling water pump running lights and road instrumented normal, successful start DSE5210_ faithful electromechanical (certified) _DSE provided by the Dongguan City, South City Zhongxin Electrical and Mechanical Services Department. Dongguan City, South City Zhongxin Electrical and Mechanical Services Department (zhongxin888.net.cn) is Dongguan, industrial products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
