Description
Technical field
The utility model relates to a kind of generator that has whole sheet string type hydrogen cooler.
Background technology
Along with China's rapid economic development, entire society increases day by day to the demand of the energy.Electric energy is in the state of supply relative deficiency as current a kind of most important energy always.In order to guarantee sufficient supply of electrical energy, at first just must guarantee to produce the stable high loaded process of the generator of electric energy.
As everyone knows, when the generator high loaded process, body temperature will sharply raise, in case body temperature surpasses certain restriction, generator just can not continue to keep steady operation, therefore must lower the temperature to generator by cooling system.
For the current hydrogen-cooled generator that generally uses, its cooling system comprises the hydrogen cooling system of the water cooling system of stator winding and stator core, rotor, and the circulating water cooling system of auxiliary special cooled hydrogen.
In spring, autumn, three seasons of winter, because ambient temperature is lower, the cold hydrogen temperature in the rotor cooling system of generator can be above 40 ℃.But because ambient temperature is very high, the circulating water temperature in the auxiliary circulating water cooling system is higher in summer, the highlyest can reach 38 ℃, over proof 33 ℃ restriction.Therefore, generator is in summer during high-load operation, and the cold hydrogen temperature potential of cooler must surpass 40 ℃ of its rated temperatures, can reach 46 ℃.If want to control cold hydrogen temperature maintenance in prescribed limit, just must reduce the generator live load, and this certainly will will have influence on generating quantity.
For these reasons, be necessary to design a kind of generator in fact with novel type of cooling, so that more effectively generator is lowered the temperature, thus the stable high loaded process of assurance generator.
The utility model content
The purpose of this utility model is to provide a kind of and can be effectively generator be lowered the temperature with the generator of the stable high loaded process that guarantees generator.
To achieve these goals, the generator that has whole sheet string type hydrogen cooler of the present utility model is design like this:
A kind of generator that has whole sheet string type hydrogen cooler, it comprises:
An inside is full of the housing of hydrogen;
A hollow stator that is arranged on the described inner walls;
A rotating shaft that is arranged on rotationally in the described housing, its end stretch out and pass described housing, are provided with potted component at its penetration site place;
In the cavity that is arranged at stator and be fixed on can be with the rotor of its rotation in the described rotating shaft;
Two fans that are separately fixed at described two ends of rotor;
A plurality of whole sheet string type hydrogen coolers that are fixed on the described inner walls,
The recirculating cooling water system that links to each other with described hydrogen cooler.
By using, can guarantee the stable high loaded process of generator and improve generating quantity effectively according to generator of the present utility model.
Description of drawings
Below, will be described in more detail embodiment of the present utility model in conjunction with the accompanying drawings, wherein:
Fig. 1 is the generator Structure schematic diagram that has whole sheet string type hydrogen cooler of the present utility model.
Embodiment
As shown in Figure 1, comprise according to a kind of generator that has whole sheet string type hydrogen cooler of the present utility model: the sealing generator housing 1, that inside is full of hydrogen is fixed on hollow stator 2 on the described housing, one and is arranged in rotating shaft 3 in the described housing, the cavity that is arranged at stator 2 rotationally and is fixed on whole sheet string type hydrogen cooler 5 that can be fixed on 4,4 of the rotors of its rotation in the described rotating shaft on four jiaos of the described inner walls and the recirculating cooling water system 6 that links to each other with described hydrogen cooler 5; Wherein, the end of rotating shaft 3 stretches out and passes described housing 1, is provided with potted component in its position that penetrates housing 1, and the sealing element is a sealing bearing bush.
Described whole sheet string type hydrogen cooler 5 radiating efficiencys are higher, and its volume is little under the condition of same capability, and the tube bank part is a whole string sheet, the whole total length pipe that rises, have enough cooperating tightly to measure between fin and cooling water pipe, because area of dissipation big than other types, whole heat exchange efficiency is higher.
Efficiently radiates heat in order to ensure generator, at first 4 whole sheet string type hydrogen coolers 5 firmly are installed on four jiaos of generator housing 1 inwalls, for example can fix by the mode that is spirally connected, and the recirculating cooling water system 6 of hydrogen cooler 5 with generator connected, for example by using the mode of Inlet and outlet water flange.In order to prevent the cold and hot wind short circuit of generator, can also adopt the oil-resisting type stripper rubber to seal.
Sheet string type hydrogen cooler 5 overall dimensions in the utility model are preferably squeezed the chip cooler with original bimetallic and are consistent.Those of ordinary skills should be known in can increase and reduce the quantity that is arranged on whole sheet string type hydrogen cooler 5 on the generator housing 1 according to the cooling needs of generator reality.
In actual use, the operating pressure of described whole sheet string type hydrogen cooler 5 is set at 0.441MPa, discharge is set at 260m
3/ h, air quantity is set at 10.5m
3/ s.After generator is started working, thereby rotor 4 rotates in stator 2 with armature spindle 3 and produces alternating current, and producing a large amount of heat energy causes the stator 2 of generator and rotor 4 temperature to raise, near adjacent stator 2 and the rotor 4, the hydrogen of sealing constantly absorbs above-mentioned heat energy in the housing 1, its gas temperature also correspondingly increases.The fan (not shown) that is installed in described rotor 4 two ends constantly blows to high-temperature hydrogen 4 hydrogen coolers 5 that are arranged on four jiaos of housing 1 inwalls, and the recirculated cooling water in this moment recirculating cooling water system 6 flows in the cooling water pipe of hydrogen cooler 5 lowers the temperature and make it become low temperature hydrogen so that can absorb rotor 4 once more and heat that stator 2 produces blowing near the cooler 5 hot hydrogens.Because fan blows away near the hydrogen the rotor 4, make near the gas pressure intensity the rotor 4 reduce, automatically flowed near the area of low pressure rotor 4 by the hydrogen after the cooling near the hydrogen cooler 5, absorb the unnecessary heat of rotor 4 and stator 2 once more, just can reduce the temperature of generator unit stator 2 and rotor 4 and so forth effectively.
Preferably, the copper pipe of whole sheet string type hydrogen cooler 5 of the present utility model adopts the manufacturing of B10 White Copper Tubes, and hydroecium adopts the stainless steel manufacturing so that have corrosion resistance.The highest inflow temperature of described hydrogen cooler 5 is 37 ℃, and minimum inflow temperature is 15 ℃, and the highest leaving air temp is 40 ℃.
When using generator of the present utility model to generate electricity, the heat exchange effect of whole sheet string type hydrogen cooler 5 is monitored.When generator load is 494MW, when circulating water temperature reached 33.1 ℃ of specified water temperatures, cold hydrogen temperature was up to 34.5 ℃; When load was 500MW, circulating water temperature was 37 ℃, and cold hydrogen temperature does not surpass 40 ℃ yet, and above-mentioned data prove absolutely that the heat exchange efficiency according to whole sheet string type hydrogen cooler 5 in the generator of the present utility model obviously improves.
By using according to the generator with whole sheet string type hydrogen cooler of the present utility model, Can effectively solve the cold hydrogen temperature of generator during the summer large load operation is above standard and asks Topic is guaranteed the stable heavy-duty service of generator, and and then improves the generating total amount of generator.
