Description

Technical Field

[0001] The utility model relates to the technical field of generator repair and maintenance, in particular to a generator water removal device. Background Art

[0002] After the generator is shut down, the cooling water in the stator coil needs to be drained. However, since the hollow wire rod structure inside the stator coil adopts Robert transposition in its design, there is a dead zone in the hollow wire rod inside the coil. The residual water in the hollow wire rod cannot be completely removed only through the generator's drain pipe.

[0003] In addition, a large amount of residual water film is attached to the inner surface of the generator outlet bushing, neutral point bushing, and ring lead. When a large generator is shut down for maintenance, it is necessary to perform stator winding insulation resistance measurement, DC withstand voltage and DC leakage current measurement, and AC withstand voltage test. Due to the residual moisture inside the generator, the surface creepage and leakage current will increase abnormally during the high-voltage electrical test of the generator, and the test result will fail.

[0037] Figure 1 This is a schematic diagram of the structure of a water removal device for a generator provided by an embodiment of the utility model, with reference to Figure 1As shown, the embodiment of the utility model provides a water removal device 10 for a generator, and the water removal device 10 includes: a gas pipeline 100, a generator 200, a heating module 300 and a solenoid valve 400; the gas pipeline 100 includes an intake manifold 110 and an exhaust manifold 120, the intake manifold 110 is connected to the steam end 201 of the generator 200, and the exhaust manifold 120 is connected to the exhaust end 202 of the generator 200; the purge medium a is transmitted to the generator 200 through the intake manifold 110, and then transmitted to the generator 200 through the exhaust manifold The air is discharged from the exhaust manifold 120; the heating module 300 is located on the intake manifold 110, and the heating module 300 is used to heat the purge medium; the solenoid valve 400 includes a first solenoid valve 410 and a second solenoid valve 420, the first solenoid valve 410 is located on the intake manifold 110, and the first solenoid valve 410 is located on a side of the heating module 300 close to the generator 200, and the second solenoid valve 420 is located on the exhaust manifold 120; the first solenoid valve 410 and the second solenoid valve 420 are used to adjust the flow rate of the purge medium.

[0038] Among them, cooling water is required during the operation of the generator 200. The cooling water flows continuously through the inside of the stator coil of the generator 200, thereby taking away the heat caused by the loss of the stator coil of the generator 200, so as to ensure that the temperature of the stator coil meets the relevant requirements of the operation of the generator 200. After the generator 200 is shut down, the cooling water needs to be discharged in time, so as to ensure the service life of the generator 200. Specifically, the cooling water can be purged by using the water removal device 10 of the generator provided in the embodiment of the utility model.

[0039] Among them, reference Figure 1 As shown, by blowing a purge medium into the generator 200, the cooling water is purged out of the generator 200, thereby realizing the dehydration process of the cooling water. Specifically, the dehydration device 10 includes a gas pipeline 100 and a generator 200, and the gas pipeline 100 includes an intake manifold 110 and an exhaust manifold 120, and the intake manifold 110 is connected to the steam end 201 of the generator 200, and the exhaust manifold 120 is connected to the exhaust end 202 of the generator 200, and the steam end 201 of the generator 200 refers to the end thereof close to the steam turbine. The purge medium ( Figure 1The purge medium a (shown as an example in FIG. 1 ) is transmitted to the generator 200 through the intake manifold 110, and the cooling water in the generator 200 is purged and removed by the continuous introduction of gas, and the removed cooling water is then discharged through the exhaust manifold 120. It should be noted that the purge medium entering the intake manifold 110 is shown as a1, and the gas discharged from the exhaust manifold 120 is shown as a2, and a1 and a2 can reflect different physical forms of the purge medium used for purging. It can be understood that the purge medium a is in the form of a compressed gas when it flows into the intake manifold 110, and through a complete set of purge processes, there may be a situation where the temperature drops and it is converted from a gaseous state to a liquid state, so that the purge medium discharged through the exhaust manifold 120 can be in the form of a liquid. That is, the physical forms of the purge medium flowing into the generator 200 and the purge medium flowing out of the generator 200 can be different.

[0040] Furthermore, the dewatering device 10 also includes a heating module 300, which is located on the intake manifold 110, and the heating module 300 is used to heat the purge medium flowing through the heating module 300, and can enter the generator 200 in the state of high-temperature gas, thereby directly heating and evaporating the cooling water in the generator 200. The evaporative purge in the prior art is based on the heat provided by a heating and drying circuit after the positive and negative pressure purge, and the residual water film can be evaporated and cleaned. The dewatering device 10 provided in the embodiment of the utility model does not need to rely on other purge processes, nor does it need to set up additional circuits. It can directly heat, evaporate and purge the generator 200, which ensures the simplification of the structure of the dewatering device 10 and also ensures the dewatering effect on the generator 200.

[0041] For further reference, Figure 1 As shown, the dewatering device 10 also includes a solenoid valve 400, which may include a first solenoid valve 410 and a second solenoid valve 420. The first solenoid valve 410 and the second solenoid valve 420 are used to control the flow rate of the flowing purge medium, so as to ensure that the heating evaporation purge process implemented by the dewatering device 10 can be finely regulated. Specifically, the first solenoid valve 410 is located on the intake manifold 110, and the first solenoid valve 410 is located on the side of the heating module 300 close to the generator 200. The opening size of the first solenoid valve 410 can be adjusted to adjust the flow size of the purge medium heated by the heating module 300. It can be understood that the first solenoid valve 410 adjusts the flow rate of the purge medium flowing into the generator 200. The second solenoid valve 420 is located on the exhaust manifold 120, and the flow rate of the purge medium flowing out of the generator 200 can be adjusted by adjusting the opening size of the second solenoid valve 420.

[0042] Optionally, the dewatering device 10 may be further provided with a safety valve (not specifically shown in the figure), which is used to ensure the normal operation of the entire purge circuit when an abnormality occurs in the first solenoid valve 410 and / or the second solenoid valve 420. That is, the safety valve is equivalent to the safety device of the solenoid valve 400, thereby reflecting the safety and reliability of the dewatering device 10 provided by the embodiment of the utility model.

[0043] In general, the dewatering device 10 provided in the embodiment of the utility model can directly heat, evaporate and purge the cooling water in the generator 200 by setting the heating module 300 on the intake manifold 110. Furthermore, by adding a solenoid valve 400 on the gas pipeline 100, the heating, evaporation and purging process achieved by the dewatering device 10 can be finely regulated, thereby ensuring the dewatering effect on the generator 200.

[0044] In summary, the dewatering device for a generator provided in the embodiment of the utility model directly heats the purge medium through the heating module, so as to directly heat the generator for evaporation and purge, thereby ensuring the dewatering effect of the generator.

[0045] Figure 2 This is a schematic diagram of the structure of another water removal device for a generator provided by an embodiment of the utility model, referring to Figure 2 As shown, the water removal device 10 also includes a detection module 500 and a host computer 600; the detection module 500 includes a temperature detection unit 510, a humidity detection unit 520 and a pressure detection unit 530, and the temperature detection unit 510, the humidity detection unit 520 and the pressure detection unit 530 are all located on the gas pipeline 100; wherein, the temperature detection unit 510 is connected to the host computer 600, and the host computer 600 is used to obtain the gas temperature information detected by the temperature detection unit 510; the humidity detection unit 520 is connected to the host computer 600, and the host computer 600 is used to obtain the gas humidity information detected by the humidity detection unit 520; the pressure detection unit 530 is connected to the host computer 600, and the host computer 600 is used to obtain the gas pressure detected by the pressure detection unit 530.

[0046] For further reference, Figure 2As shown, the dewatering device 10 may also include a detection module 500, which can detect the purge medium circulating in the gas pipeline 100, further improving the safety and reliability of the dewatering device 10. The dewatering device 10 may also include a host computer 600, which is connected to the detection module 500, and can timely feedback the purge medium situation of the detection module 500, and adjust the purge medium in time in combination with the feedback situation in combination with the parameters and programs pre-set by the host computer 600. Exemplarily, the host computer 600 may also include a human-computer interaction interface, such as a computer terminal, through which the user can adjust the purge medium in real time according to the obtained detection results, reflecting that the adjustment of the dewatering device 10 is flexible, and it can also reflect that the dewatering effect of the dewatering device 10 is guaranteed to a certain extent.

[0047] Specifically, the detection module 500 includes a temperature detection unit 510, a humidity detection unit 520, and a pressure detection unit 530, and the temperature detection unit 510, the humidity detection unit 520, and the pressure detection unit 530 are all located on the gas pipeline 100, so as to detect the temperature, humidity, pressure, etc. of the purge medium in the gas pipeline 100. And the different detection units are all connected to the host computer 600, so as to ensure that the host computer 600 can obtain the purge medium in multiple dimensions, so as to make more accurate adjustments to the purge medium, so as to ensure a better purge effect on the cooling water of the generator 200.

[0048] Continue to refer Figure 2 As shown, the temperature detection unit 510 is located on the intake manifold 110 and on the side of the heating module 300 close to the first solenoid valve 410; the heating module 300 is connected to the host computer 600; wherein the host computer 600 adjusts the heating temperature of the heating module 600 according to the gas temperature information, and / or the host computer 600 adjusts the opening of the solenoid valve 400 according to the gas temperature information.

[0049] For further reference, Figure 2 As shown, the temperature detection unit 510 is located at the intake manifold 110 and at a side of the heating module 300 close to the first solenoid valve 410. The gas temperature information detected by the temperature detection unit 510 may refer to the gas temperature after heating by the heating module 300. It can also be understood that the gas temperature information detected by the temperature detection unit 520 refers to the gas temperature information flowing into the generator 200. Exemplarily, the temperature detection unit 520 may be a temperature sensor.

[0050] Furthermore, the host computer 600 judges the acquired gas temperature information by comparing it with the temperature parameters pre-stored in the host computer 600. If the detected gas temperature information is less than the pre-stored temperature parameters, it proves that the current purge medium temperature is relatively low. The host computer 600 is connected to the heating module 300, and the heating temperature of the heating module 300 is increased by controlling the temperature of the heating module 300 to ensure that the purge medium is heated; and / or, the host computer 600 is connected to the first solenoid valve 410 and the second solenoid valve 420, and the opening of the first solenoid valve 410 and the second solenoid valve 420 is reduced by controlling the opening of the first solenoid valve 410 and the second solenoid valve 420 to ensure that the flow rate of the purge medium is slowed down, so that sufficient time can be used for heating. The judgment method can also be that the user directly judges that the detected gas temperature information is low through the temperature information fed back by the human-computer interaction interface connected to the host computer 600. Similarly, the host computer 600 is connected to the heating module 300, and the heating temperature of the heating module 300 is increased by controlling the heating temperature of the heating module 300 to ensure that the purging medium is heated; and / or, the host computer 600 is connected to the first solenoid valve 410 and the second solenoid valve 420, and the opening of the first solenoid valve 410 and the second solenoid valve 420 is reduced to ensure that the flow rate of the purging medium is slowed down, so that there is enough time for heating. The above is only an example of the case where the temperature of the purging medium is detected to be low. If the temperature of the purging medium is detected to be high, the heating temperature of the heating module 300 can be reduced, or the opening of the first solenoid valve 410 and the second solenoid valve 420 can be increased. In general, the heating module 300 and / or the solenoid valve 400 are adjusted in combination with the detected temperature to ensure the dewatering effect of the generator 200.

[0051] Optional, reference Figure 2 As shown, the heating module 300 includes a heating unit 310 and a constant temperature unit 320 .

[0052] For further reference, Figure 2 As shown, the heating module 300 includes a heating unit 310, which can ensure the efficiency of heating the purge medium.

A first humidity detection unit 521 is set on the intake manifold 110, and a second humidity detection unit 522 is set on the exhaust manifold 120.

[0059] Optional, continue to refer to Figure 2 As shown, the water removal device 10 further includes a pressure reducing valve 700 ; the pressure reducing valve 700 is located on the intake manifold 110 and is located on a side of the heating module 300 away from the generator 200 .

[0060] For further reference, Figure 2 As shown, the water removal device 10 may also include a pressure reducing valve 700, which is a valve that automatically maintains a stable outlet pressure by relying on the energy of the circulating medium itself. The pressure reducing valve 700 is set on the intake manifold 110 and is located on the side of the heating module 300 away from the generator 200. The pressure of the purge medium flowing into the intake manifold 110 can be adjusted within a certain limit. If the pressure of the purge medium circulating in the intake manifold 110 is abnormal, the pressure reducing valve 700 can be automatically adjusted within a certain limit to ensure that the gas pressure of the purge medium flowing into the generator 200 is stable. Further, combined with the opening adjustment of the first solenoid valve 410 and the second solenoid valve 420, the pressure of the gas in the entire gas pipeline 100 can be better adjusted, thereby ensuring the effect of purging the cooling water of the generator 200.

[0061] Continue to refer Figure 2As shown, the water removal device 10 further includes an air-water separator 800 ; the water separator 800 is located on the air intake manifold 110 and on a side of the heating module 300 away from the generator 200 .

[0063] Continue to refer Figure 2 As shown, the water removal device 10 further includes a condenser 900 ; the condenser 900 is located on the exhaust manifold 120 and is located on a side of the second solenoid valve 420 away from the generator 200 .

In combination with the dewatering device 10 provided in the embodiment of the utility model, the condenser 900 is responsible for condensing the superheated gas flowing out of the generator 200.

Further, the water removal device 10 may also include a water storage tank (not specifically shown in the figure), which is responsible for collecting the residual water discharged from the exhaust main pipe 120.

[0066] Figure 3 This is a schematic diagram of the structure of another water removal device for a generator provided by an embodiment of the utility model, referring to Figures 1 to 3 As shown, the exhaust main pipe 120 also includes at least one exhaust branch 121, one end of the exhaust branch 121 is connected to the exhaust end 202 of the generator 200, and the other end of the exhaust branch 121 is connected to the exhaust main pipe 120; the number of exhaust branches 121 corresponds one-to-one to the number of exhaust ends 202 of the generator 200.

[0067] Specifically, the generator 200 may have different numbers of exhaust ports 202. Figure 1 and Figure 2 In the description, the generator 200 includes an exhaust port 202 as an example.
