configuration of multi-voltage genset
1.1 Summary of multiple voltage genset

Due to the different requirements of the power generator set application or the diversity of the input power supply voltage of the user terminal load.At this time, it is necessary to have a generator set with multiple voltage AC power outputs.

GTL 1500KW/220V 3P/4W--380V 3P 4W multiple voltage Generator set
1.2 Classification of multiple voltage output generator sets
a. The load method of the small power section can be realized by a universal transfer switch. This way can support switching of 3 different voltages.
b. Users who have professional electrical maintenance of generator sets on site can choose manual modification. It can be realized by changing the connection point of the copper bar, this method can support the changing of 3 different voltages.
c. Optional application of dual power switch, it can be realized by changing the wiring mode of the generator winding and automatically switching the voltage. This method can support the switch of 2 different voltages.


Universal conversion manual switching mode Manually change the copper bus way Dual power switching changes winding wiring

1.3 configuration of multiple voltage generator sets

A. Universal conversion manual switching mode: the main circuit breaker of the generator set (the rated current is calculated according to the minimum voltage segment and the minimum number of phases),universal transfer switch, the main circuit breaker to the universal transfer switch and the universal transfer switch to the generator connection cable, the control system has a variety of voltage properties protection, AVR wiring adjustment.

B. Manual change the copper bus way:The main circuit breaker of the generator set (the rated current is calculated according to the minimum voltage segment and the minimum number of phases), a variety of voltage switching insulation boards, the main circuit breaker to the insulation board and the insulation board to the generator connection cable, the control system has a variety of voltage properties Protection, wiring adjustment for AVR

C.Dual power switching to change the winding wiring method: The main circuit breaker of the generator set (the rated current is calculated according to the minimum voltage segment and the minimum number of phases), 2 double power switches and their control components, the main circuit breaker to the double power switch and the double power switch to the generator connection cable, the control system has A variety of voltage properties protection, AVR wiring adjustment.

1.4 Alternator selection requirements for multiple voltage generator sets

The working principle of various voltage switching: Since the 12-wire generator winding can be adjusted, according to the generator winding wiring schematic diagram, it can output: 1. The series star winding wiring output:380V-415V/50Hz and 380V-480V/60HZ;2. Parallel star winding wiring output:190V-208V/50HZ and190V-240V/60HZ: Double delta winding wiring output: 220V-240V/50HZ and 220V-240V/60HZ.
