The utility model belongs to nuclear power plant's moving emergency power technique fields, is specifically related to press in a kind of nuclear power plant mobile diesel-oil electric generator wagon.
Background technique
Nuclear power plant's emergency power supply is the necessary equipment of alleviating the station blackout event, and after the Fukushima, Japan event occured, State Bureau of Nuclear Safety had issued " after the Fukushima nuclear accident, nuclear power plant improves the action current techique and requires (trying) ".According to the rules, nuclear power plant need to configure the mobile emergency diesel generating set.
According to usual diesel fuel generator set design code, pressing diesel engines at present designs with the parameter matching that generator power equates substantially, be that diesel engine and generator power ratio is less than or equal to 1:1, as 1:0.9,1:0.8, can not satisfy large motor load starting resistor under nuclear power station station blackout state falls≤and 25% band carries requirement, and namely the generator voltage that causes of motor start-up falls excessive.
Particularly, the diesel generator parameter that generally adopts in prior art is as shown in the table:
In addition, the radiator of water tank volume that the larger requirement of diesel generation acc power matches is larger, and therefore, portable diesel generator size mainly is limited by the size of diesel engine radiator radiator.Diesel generator size of the prior art is difficult to satisfy the requirement of portable diesel generator.
The model utility content
The utility model technical issues that need to address are: diesel generator of the prior art, its diesel engine and generator power ratio are less than or equal to 1:1, can not satisfy large motor load starting resistor under the nuclear power station off-position falls≤25% requirement, and namely the generator voltage that causes of motor start-up falls excessive.
The technical solution of the utility model is as described below:
Press mobile diesel generator in a kind of nuclear power plant, comprising: diesel engine, generator, generator outlet circuit breaker, starting storage battery and Trolley; Starting storage battery is used for starting diesel engine, diesel engine is connected with generator by shaft joint, the output of generator is transferred to external equipment by the generator outlet circuit breaker, and diesel engine, generator, generator outlet circuit breaker, starting storage battery are arranged on Trolley, can move power supply.
Described diesel engine and generator power are 1:1.4 than between 1:1 ~ 1:2 as diesel engine and generator power ratio.
The beneficial effect that the utility model is obtained is:
(1) press mobile diesel-oil electric generator wagon in nuclear power plant of the present utility model, its diesel engine and generator power are than between 1:1 ~ 1:2, reduced the generator voltage that motor start-up causes and fallen, satisfying large motor load starting resistor under the nuclear power station off-position falls≤and 25% band carries requirement;
(2) press mobile diesel-oil electric generator wagon in nuclear power plant of the present utility model, in the situation that do not change diesel engine power, power by suitable increase generator, and generator is less on the boundary dimension impact of whole unit, thereby can satisfy the requirement of mobile diesel generator boundary dimension, for pioneering, extremely has promotional value both at home and abroad.
