Description

A kind of cooling system of generating set
Technical field
This utility model relates to generator system, particularly relates to the cooling system of a kind of generating set.
Background technology
At present, the use of electromotor is very universal, and high-rating generator often continuous firing, drive motor is sent out The electromotor of electricity can persistently produce heat, if these heats are got rid of not in time, it will affect generating efficiency, Result even in engine damage, cause heavy losses.Because hydrogen has preferable cooling performance, lead at present If being cooled down by hydrogen cooler electromotor.
Usual enterprise can arrange two electromotors and generate electricity in turn, the most supporting hydrogen cooler of each electromotor And hydrogen dryer, by the enclosed cooling water pump cooling water supply of self correspondence, due to method of operation reason, General only one electromotor of unlatching, it is contemplated that sake of economy, the enclosed cooling water pump of the electromotor of stoppage in transit is not Opening, the hydrogen cooler of the electromotor so stopped transport just does not has chilled(cooling) water supply (CWS), it is impossible to normally put into operation. Do not put into hydrogen dryer during shutdown, the humidity of generator hydrogen can be affected, reduce the insulation of electromotor Property.So wherein a generator outage time, in order to corresponding hydrogen dryer normally comes into operation, close Formula water system is accomplished by reopening, and starting big closed Water System i.e. wastes electricity, adds again operation Operational ton.
Because above-mentioned defect, the design people, the most in addition research and innovation, a kind of do not opening to founding On the premise of open-close type water system, hydrogen dryer also can the cooling system of generating set of bringing normally into operation, make It has more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide the cooling water of a kind of two electromotors The cooling system of generating set that can be the most standby.
The cooling system of generating set of the present utility model, described generating set includes two electromotors, each described Electromotor all includes electromotor and connected motor, and described cooling system includes two hydrogen coolers, two Described hydrogen cooler carries hydrogen respectively through the housing of electromotor described in two, and is connected by pipeline respectively Having hydrogen dryer, the port of export of hydrogen dryer described in two is cold by hydrogen described in described pipeline and two respectively But device arrival end connect, the cooling water oral siphon of hydrogen cooler described in two pass through the first cross current, two The return pipe of described hydrogen cooler passes through the second cross current, and described first water pipe and the second water pipe are all provided with There are two stop valves.
Further, two air accumulators that described cooling system is provided hydrogen, air accumulator described in two are also included Outlet connects hydrogen cooler described in two respectively by described pipeline.
Further, the two described hydrogen dryers of connection further respectively have on the described pipeline of described air accumulator Hydrogen filter.
Further, hydrogen desiccation agent all it is filled with in hydrogen dryer described in two.
By such scheme, this utility model is by connecing the oral siphon of two hydrogen coolers respectively with return pipe Logical, the cooling water that can make two hydrogen coolers is the most standby, it is to avoid because of hydrogen when wherein an electromotor is stopped transport Gas dryer cannot the defect brought of regular supply because of cooling water, it is ensured that the bringing normally into operation of hydrogen dryer, Greatly strengthen hydrogen desiccation degree, improve the reliability of generator operation.
Described above is only the general introduction of technical solutions of the utility model, in order to it is new to better understand this practicality The technological means of type, and can be practiced according to the content of description, below with preferable reality of the present utility model After executing example and coordinating accompanying drawing to describe in detail such as.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail. Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
See Fig. 1, the cooling system of a kind of generating set described in this utility model one preferred embodiment, generating Unit includes two electromotors, the electromotor 11 being respectively connected and motor 12, the electromotor 21 being connected With motor 22, cooling system includes two hydrogen coolers 13,23, hydrogen cooler 13,23 respectively through Electromotor 11,21 housing conveying hydrogen, and respectively by pipeline 14,24 connect hydrogen dryer 15, 25, the port of export of hydrogen dryer 15,25 connects hydrogen filter 16,26 respectively, hydrogen filter 16, 26, the port of export be connected with the arrival end of hydrogen cooler 13,23 by pipeline 14,24 respectively.Hydrogen The cooling water oral siphon of cooler 13,23 is connected by the first water pipe 30, returning of hydrogen cooler 13,23 Water pipe is connected by the second water pipe 40, is equipped with two stop valves 50 on the first water pipe 30 and the second water pipe 40. So, when one of them electromotor such as stop transport with motor 12 by electromotor 11, hydrogen cooler 13 is supplied water Water pump also can stop transport, electromotor that another electromotor is i.e. connected 21 and motor 22 still work, phase Answering, the water pump supplying water hydrogen cooler 23 still supplies water, due to the cooling of hydrogen cooler 13,23 Water oral siphon is connected by the first water pipe 30, opens two stop valves 50 on the first water pipe 30, hydrogen_cooling The cooling water of device 23 is entered in hydrogen cooler 13 by the first water pipe 30, thus hydrogen cooler 13 can To cool down the hydrogen in pipeline 14, making hydrogen be maintained at relatively low temperature, hydrogen dryer 15 is also Can continue hydrogen is dried, it is ensured that the aridity of hydrogen, to guarantee the insulating properties of electromotor.Again because of hydrogen The return pipe of Gas Cooler 13,23 is connected by the second water pipe 40, opens two cut-offs on the second water pipe 40 Valve 50, the cooling water of hydrogen cooler 13 flows into hydrogen cooler 23 through its return pipe by the second water pipe 40 Return pipe discharge.
This utility model is respectively provided with two stop valves 50 on the first water pipe 30 and the second water pipe 40, be in order to In the case of preventing stop valve 50 inefficacy wherein, another stop valve 50 still can play cut-off Effect.
When utilizing hydrogen that electromotor is cooled down, need pipeline 14,24 loop being carried out mend hydrogen, this practicality Novel is to be all connected with air accumulator 16,26 on pipeline 14,24, and pipeline is passed through in the outlet of air accumulator 16,26 14,24 connect hydrogen cooler 13,23 respectively.
This utility model is respectively provided with hydrogen filter 17,27 on pipeline 14,24, is to ensure that the pure of hydrogen Degree, to guarantee cooling effect.
Hydrogen is dried by this utility model by filling hydrogen desiccation agent in hydrogen dryer 15,25, Low cost.
This utility model, by being respectively turned on return pipe by the oral siphon of two hydrogen coolers, can make two hydrogen The cooling water of Gas Cooler is the most standby, it is to avoid because of when wherein electromotor is stopped transport hydrogen dryer because of cooling Water cannot the defect brought of regular supply, it is ensured that the bringing normally into operation of hydrogen dryer, greatly strengthen hydrogen Aridity, improves the reliability of generator operation.
The above is only preferred implementation of the present utility model, is not limited to this utility model, should When pointing out, for those skilled in the art, without departing from this utility model know-why On the premise of, it is also possible to making some improvement and modification, these improve and modification also should be regarded as this utility model Protection domain.
