The present invention discloses an integrated multistage transformation emergency power supply device for a generator set. The device comprises a low-voltage output circuit breaker, a transformer input circuit breaker and a first switching circuit breaker which are electrically connected with the output end of the generator set, the low-voltage output circuit breaker is connected with a low-voltage output interface, the transformer input circuit breaker is connected with the low-voltage side of a transformer, the high-voltage side of the transformer is connected with the high-voltage output circuit breaker, the high-voltage output circuit breaker is connected with the high-voltage output interface, and the input end of the generator set and the first switching circuit breaker are respectively connected with the second switching circuit breaker; and the generator set is provided with a voltage selection switch capable of controlling the first switching circuit breaker and the second switching circuit breaker to be switched on and switched off, so that the connection mode of all windings in the generator set is changed, the output voltage of the generator set is controlled to be changed, and the problem that an existing common generator set needs multi-voltage output can be solved.
Description
technical field [0001] The invention relates to the field of emergency power supply, in particular to an integrated multi-stage transformer emergency power supply device for a generating set. Background technique [0002] In areas where disasters such as typhoons and floods occur, power equipment will generally be damaged, resulting in large-scale power outages and cannot be repaired in a short time; and for urban drainage stations that need to quickly drain urban water, generally need generator sets to provide Emergency power supply; due to the different water pumps in the drainage station, the power supply provided by the generator set has different voltage levels; at present, there is no such multi-voltage level generator set in China. At present, ordinary generator sets on the market are aimed at a single electric load, and their output voltage is fixed, mostly 400V and 10.5kV, while general large-scale drainage stations have different pumping stations in different locat...
