When the generator rental Dongguan diesel generator set diesel generator [ratings] professional major business generator sales, leasing, maintenance and related works of a range of services. 200-3000KW stock company for many years about 500 various models of generators, generator Dongguan, Shenzhen, generators, generator rental business as a starting point Guangzhou, Dongguan and generator rental generator sets for the provision of ancillary services ...... (1) Rated power (pe): refers to the maximum active power diesel generators at nominal operating conditions can output in kilowatts (kW) or megawatts (MW). (2) Rated power factor (cosφ): refers to the power factor of the motor rated at runtime. (3) Rated voltage (Ue): refers to the diesel generator set during normal operation of the line voltage, in volts (V) or kilovolt (kW). (4) rated current (Ie): refers to the diesel generator set running at the rated line current state generator repair plant, the unit is safe (A) or kA (kA). (5) rated speed (nc): diesel generators to maintain the frequency of alternating current is 50Hz required speed in revolutions / min (r / min). (6) Rated efficiency (ηe): refers to the efficiency of the diesel generator set running at rated state. (7) Rated frequency (fe): China provides a nominal frequency of 50Hz. (8) the nominal temperature: running diesel generators allow the stator winding and rotor windings than the ambient temperature in degrees. China provides the ambient temperature is calculated to 40 ℃. Unattended automated microwave generators, cable repeater stations with generators unattended automation In addition to having an ordinary turbine technical indicators, but also has the following indicators of an automated, self-starting when the electricity is interrupted, or phase voltage exceeds 380V (-15- + 10%) after the open range or ground away 300kw generator maintenance instructions, the unit should be able to automatically start, start cycle includes three cat generator maintenance, start-up time 3 ~ 10s each generator maintenance, start interval lot in the 30s, the total time to start no more than 120s, start should be greater than 99% success rate. 2, automatic loading and unloading switching power cut, after the success of the unit from the start, the unit automatically switches to the main power supply load, if the main fault with the unit, the unit automatically switches to the backup power supply. When utility power is restored to normal, automatic back to the mains supply, then unload the unit automatically shut down after a delay 3 ~ 5min. 3, automatic protection shutdown occurs when one of the following breakdown by unit, the unit automatically shut down to protect and send messengers signal: (1) high voltage or low voltage (2) oil pressure (3) high temperature (water-cooled units) (4) high speed or low speed (5) high frequency or low frequency 4, the unit should be able to automatically maintain the oil temperature in the range of 20 ~ 30 ℃, the cooling water temperature is in the range of 30 ~ 50 ℃ 5, the battery unit should be able to start automatically charging, automatic supply of fuel, oil and cooling water should be able to meet the continuous (or cumulative) run 240h.
