Furthermore, in the following description, when referring to the drawings, the same reference numerals in different drawings denote the same or similar elements unless otherwise explained.
According to one embodiment of the present disclosure, a wind turbine control cabinet is provided, which may include a cabinet body 1, and a first vent 111 and a second vent 112 provided on the cabinet body 1. The cabinet 1 has a housing chamber formed by a top wall, a bottom wall and a plurality of side walls, a dry-type transformer 10 is arranged in the housing chamber, and one side wall of the cabinet 1 is a cabinet door 11 which can be opened and closed. The first air vent 111 may be provided at an upper portion of the cabinet door 11, and the first fan 2 is provided in the first air vent 111. The second air port 112 may be disposed on the cabinet door 11 below the first air port 111, and the second fan 3 is disposed in the second air port 112. The first air vent 111 may be located at the same height as one of the second air vents 112 and the dry-type transformer 10, and disposed opposite to the dry-type transformer 10, and one of the first fan 2 and the second fan 3 is used for guiding the air in the cabinet 1 to the outside of the cabinet 1, and the other is used for guiding the air outside the cabinet 1 to the cabinet 1.
The opposite arrangement here means that the dry-type transformer 10 is not offset from one of the first air vent 111 and the second air vent 112, and, for example, the dry-type transformer 10 and the second air vent 112 are seen at least partially from the inside of the cabinet 1 in the horizontal direction of the second air vent 112 when the second air vent 112 is not shielded.
Through the above technical scheme, the first air vent 111 and the second air vent 112 are arranged on the cabinet door 11 of the control cabinet, and the first fan 2 and the second fan 3 with different wind directions are arranged in the first air vent 111 and the second air vent 112 so as to accelerate the circulation of air in the cabinet body 1 and radiate heat to internal components. Meanwhile, as the part with the largest heat source in the cabinet body 1, namely the dry-type transformer 10 is closer to one of the air vents, the dry-type transformer 10 can be cooled better by the arrangement, so that the problem of heat dissipation of the control cabinet is solved, and the control cabinet can continuously operate in an environment with overhigh temperature to ensure that the corresponding wind turbine generator can operate without faults.
Further, the first fan 2 may be used to guide the air in the accommodation chamber to the outside of the cabinet 1, and the second fan 3 may be used to guide the air outside of the cabinet 1 to the accommodation chamber. Namely, the second air vent 112 is an air inlet, the first air vent 111 is an air outlet, and the temperature of the air is increased after the air enters the cabinet body 1 because the temperature of the air is reduced by the parts inside the cabinet body 1, so that the air inlet is arranged at the bottom because the density of the high-temperature air is smaller and can automatically move upwards under the condition of no external interference, the air outlet is arranged at the top so as to conform to the air flow direction inside the cabinet body 1, so that the high-temperature air is prevented from being reversely blown to the parts to be cooled, meanwhile, the high-temperature air is lost in the rising process, the temperature can be reduced by 1-2 ℃, and the heat exchange can be fully performed with the side wall of the cabinet body 1, so that a weak heat dissipation effect is provided for the internal parts. In addition, regarding the arrangement of the first fan 2 and the second fan 3, the installation direction of the first fan 2 may be opposite to the installation direction of the second fan 3, or the first fan 2 and the second fan 3 may be installed in the same direction but in opposite rotation directions, which is not limited in the present disclosure.
Further, as shown in fig. 1 to 4, the dry-type transformer 10 may be disposed on the bottom wall adjacent to the second ventilation opening 112. The dry-type transformer 10 is closer to the air inlet so as to obtain air with lower temperature at the first time, and the heat dissipation effect of the dry-type transformer 10 is better.
According to one embodiment of the present disclosure, as shown in fig. 3 and 4, the side wall of the cabinet body 1 opposite to the cabinet door 11 is further provided with a third ventilation opening 113. The cabinet 1 may be rectangular, where the opposite side walls refer to the side walls that are not connected to the cabinet door 11. The third air vent 113 may be configured to accelerate the flow of hot air from the cabinet 1, thereby improving the heat dissipation effect, and the third air vent 113 may be configured to have a fan or not.
Further, as shown in fig. 3 and 4, the third air vent 113 may be disposed opposite to the second air vent 112 to enhance the heat dissipation effect of the dry-type transformer 10. It should be noted that, the opposite arrangement herein means that the third air opening 113 and the second air opening 112 are not arranged in a staggered manner, that is, in the case that the third air opening 113 is not shielded and the components inside the cabinet 1 are removed, the outside of the cabinet 1 can be at least partially seen through the second air opening 112 when the cabinet 1 is seen in the right front direction of the third air opening 113 in the horizontal direction.
According to an embodiment of the disclosure, as shown in fig. 1 and 2, the wind turbine control cabinet further includes a temperature monitoring element 4 disposed on a cabinet door 11, so as to monitor a temperature condition of the control cabinet, and when the temperature exceeds a preset value, the control parts of the first fan 2 and the second fan 3 may be alarmed and stopped, and may also be communicated so as to cool the control cabinet.
Further, as shown in fig. 1 to 3, a temperature monitoring element 4 is provided at the first vent 111 for detecting the temperature of the gas led out at the first vent 111. When the first fan 2 and the second fan 3 are operated, that is, external air is blown in from the second air port 112 to cool the interior of the cabinet body 1, and then blown out from the first air port 111, the temperature of the air will rise at this time, if the temperature of the air is too high, the temperature of the components in the cabinet body 1 is too high, the cooling does not reach the predetermined effect, and at this time, the wind speeds of the first fan 2 and the second fan 3 can be increased to improve the cooling effect. The temperature monitoring element 4 may include a display portion and a detection portion, both may be integrally disposed on the outer side of the cabinet door 11, or may be disposed inside the cabinet body 1, and the display portion is disposed on the outer side of the cabinet door 11, so that an operator can watch and record the temperature at the first air vent 111 in real time.
According to an embodiment of the disclosure, a temperature control element and a control unit of a wind turbine control cabinet may be further disposed in the accommodating cavity, the temperature control element is connected with the temperature monitoring element 4 and the control unit, respectively, and the temperature control element may be further connected with the first fan 2 and the second fan 3. When the temperature monitoring element 4 monitors the temperature of the corresponding position, the temperature information of the corresponding position is transmitted to the control unit, if the temperature information acquired by the control unit exceeds a preset value, the control unit transmits a signal to the temperature control element, and the temperature control element can control the wind speed of the first fan 2 and the wind speed of the second fan 3 to be increased so as to improve the heat dissipation effect. In this process, the temperature monitoring element 4 always transmits temperature information to the control unit, and if the temperature information acquired by the control unit falls back within a preset range, the temperature control element can control the wind speeds of the first fan 2 and the second fan 3 to be reduced so as to reduce energy consumption while meeting the requirement of heat dissipation. If the temperature information acquired by the control unit exceeds the warning value, the control unit can alarm or stop according to a preset program to wait for subsequent overhaul of staff. The following table is the measured temperature according to the actual use condition when different fan wind speeds are different from the loads of the wind turbine corresponding to the control cabinet, the wind speeds of the first fan 2 and the second fan 3 can be equal, and the fan wind speeds refer to the wind speeds of the first fan 2 and the second fan 3 at the same time.
According to one embodiment of the present disclosure, the first fan 2 and the second fan 3 may be disposed in series, so as to ensure that the first fan 2 and the second fan 3 may be started and stopped simultaneously, which is convenient for control.
Further, as shown in fig. 1 and 2, the wind turbine control cabinet may further include a switch 5 disposed on the cabinet door 11, the switch 5 may be disposed on an outer side of the cabinet door 11, and the switch 5 is disposed in series with the first fan 2 and the second fan 3. When the first fan 2 and the second fan 3 need to be turned on or turned off, the first fan 2 and the second fan 3 can be turned on or turned off manually only by pressing the switch 5 outside the control cabinet, so that on-site emergency can be dealt with.
