Description

Technical Field

[0001] The present invention relates to the technical field of voltage stabilization, and in particular to a voltage stabilization control device. Background Art

[0002] Reactive power compensation cabinets are usually composed of capacitors, reactors, controllers, etc.

[0003] Capacitor: One of the most important components in the reactive power compensation cabinet, used to provide reactive power compensation. The capacity and quantity of capacitors are selected according to the needs of the power system;

[0004] Reactor: used to limit the surge current generated when the capacitor is put into the power grid, protecting the capacitor and other equipment from damage due to overcurrent;

[0005] Controller: Responsible for monitoring the power factor, reactive power and other parameters of the power system, and controlling the switching of capacitors according to the set target values. The controller can realize functions such as automatic switching and automatic adjustment.

[0006] The working principle of the reactive power compensation cabinet is to use the reactive power generated by the capacitor to compensate for the inductive reactive power, thereby improving the power factor. The reactive power compensation cabinet can adjust the reactive power in the power system to stabilize the voltage within the allowable range and prevent the occurrence of voltage collapse accidents. When the inductive loads in the power system (such as motors, transformers, etc.) consume reactive power, the capacitors in the reactive power compensation cabinet will be put into the power grid to provide reactive power, so that the reactive power in the power grid is balanced, thereby improving the power factor. The controller will automatically adjust the switching of the capacitor according to the parameters such as the power factor monitored in real time to keep the power factor within the set target range.

[0007] The Chinese patent with announcement number CN205544308U discloses a reactive power compensation voltage device, including a shell and a switch door connected to the shell, a controller is arranged inside the switch door; a heat dissipation hole is arranged at the bottom of the outer side of the shell; a reactor is arranged inside the shell, a capacitor is arranged on the top of the reactor, and a semiconductor device is arranged on the top of the capacitor; a circuit breaker is arranged at the top of the shell, and a transformer and a lightning arrester are arranged on one side of the circuit breaker; a current transformer is arranged between the capacitor and the circuit breaker. The above-mentioned reactive power compensation voltage device plays a role in improving the power factor of the power grid in the power supply system, reducing the loss of the power supply transformer and the transmission line, increasing the service life of components, and improving the power supply efficiency.

[0008] However, the above-mentioned reactive power compensation voltage device only uses the heat dissipation holes opened at the bottom of the outer shell for passive heat dissipation, and the heat dissipation effect is poor. Moreover, if it is used outdoors, a large amount of outdoor dust will enter the reactive power compensation cabinet through the heat dissipation holes. A large amount of dust accumulates in the reactive power compensation cabinet, further reducing the heat dissipation effect. Moreover, the dust accumulated on the lines in the reactive power compensation cabinet can easily cause line short circuit, resulting in poor safety.

[0009] Therefore, a voltage stabilization control device is proposed. Summary of the invention

[0061] The ventilation mechanism 3 includes a blower 301, a first ventilation pipe 302, a first three-way valve 303, and a second air distribution pipe 304. Two second air distribution pipes 304 are provided, and the two second air distribution pipes 304 are respectively arranged in the corresponding filtering areas. The blower 301 is fixedly installed inside the assembly box 2. The air outlet of the blower 301 is connected with the first ventilation pipe 302. The first three-way valve 303 is installed on the first ventilation pipe 302. The two air outlets of the first three-way valve 303 are respectively connected with the air inlet of the corresponding second air distribution pipe 304.

[0062] The drying mechanism 5 includes a water vapor separator 501, which is fixedly installed on the top of the water storage tank 401 through supporting legs. A third three-way valve 505 is installed at the air inlet of the water vapor separator 501. The upper ends of the two filtering areas are connected with air supply pipes 504, and the lower ends of the air supply pipes 504 do not contact the filtered water in the filtering area. The upper end of the air supply pipe 504 is connected to the air inlet of the third three-way valve 505. A second three-way valve 503 is installed at the water outlet of the water vapor separator 501. The two water outlets of the second three-way valve 503 are connected with return pipes 502. The lower ends of the two return pipes 502 extend into the interior of the corresponding filtering area respectively. The lower ends of the return pipes 502 do not contact the filtered water in the filtering area. The air outlet of the water vapor separator 501 is connected with an air outlet pipe, and the upper end of the air outlet pipe penetrates the assembly box 2 and then extends into the lower end of the interior of the reactive power compensation cabinet body 1.

[0063] A first air distribution pipe 7 is fixedly installed on the inner bottom of the reactive compensation cabinet body 1. The first air distribution pipe 7 is arranged in a spiral line, and a number of air injection holes are equidistantly opened on the first air distribution pipe 7; a temperature sensor 10 is fixedly installed on the inner top of the reactive compensation cabinet body 1, and a control panel 6 is embedded on the door panel of the reactive compensation cabinet body 1. A PLC controller is fixedly installed on the inner side of the control panel 6. The temperature sensor 10 is electrically connected to the signal input end of the PLC controller. The blower 301, the first three-way valve 303, the second three-way valve 503, and the third three-way valve 505 are all controlled by the PLC controller. A touch display screen 11 is installed on the control panel 6, and the touch display screen 11 is electrically connected to the PLC controller. By operating the touch display screen 11, it can be set to use one of the filter areas for air filtering and the other filter area for receiving water separated by the water-gas separator 501.

[0064] By adopting the above technical scheme, when in use, the ventilation mechanism 3, filtering mechanism 4, drying mechanism 5 and first air distribution pipe 7 can filter the outside air through water, and leave the dust in the air in the water body. The filtered air is then separated from the water vapor by the drying mechanism 5, and the dry air is sent into the reactive compensation cabinet body 1, so that the inside of the reactive compensation cabinet body 1 is circulated and quickly dissipated to effectively prevent the outside dust from entering the inside of the reactive compensation cabinet body 1.

[0065] During operation, first pre-set one of the filter areas for air filtration and one of the filter areas for receiving the water separated by the water vapor separator 501 by operating the touch display screen 11. For example, one of the filter areas is recorded as A and the other filter area is recorded as B. When A is used for air filtration, the third three-way valve 505 is controlled to connect the air supply pipe 504 on A with the air inlet of the water vapor separator 501, and the first three-way valve 303 is controlled to connect the air outlet of the blower 301 with the second air distribution pipe 304 in A. The water outlet of the water vapor separator 501 is connected to the return pipe 502 on A by controlling the second three-way valve 503. At this time, A is used to receive the water separated by the water vapor separator 501. The second three-way valve 503 can also be controlled to connect the water outlet of the water vapor separator 501 with the return pipe 502 on B. At this time, B will be used to receive the water separated by the water vapor separator 501. After the setting is completed:

[0066] When the temperature inside the reactive compensation cabinet body 1 exceeds the set temperature threshold, the temperature sensor 10 transmits the temperature signal to the PLC controller, and the PLC controller controls the blower 301 to start, and the outside air enters and exits A through the second air distribution pipe 304. By setting the second air distribution pipe 304 to a serpentine shape, the air and the water body can be fully in contact, thereby improving the dust filtering effect. The air after water filtration enters the water-gas separator 501 for water-gas separation, and the dried air enters the reactive compensation cabinet body 1 through the first air distribution pipe 7, thereby allowing the heat in the reactive compensation cabinet body 1 to dissipate to the outside through the heat dissipation port 1011.

[0067] In this embodiment, an opening and closing mechanism 8 is provided on the outside of the heat dissipation cover 101, and the opening and closing mechanism 8 includes a baffle plate 802, and the upper end of the baffle plate 802 is hinged to the upper end of one side of the heat dissipation cover 101. When the ventilation mechanism 3 does not ventilate the inside of the reactive compensation cabinet body 1, the baffle plate 802 can cover the heat dissipation port 1011 under the action of its own gravity. When the ventilation mechanism 3 ventilates the inside of the reactive compensation cabinet body 1, the baffle plate 802 can be lifted up by the air pressure inside the reactive compensation cabinet body 1, so that the heat dissipation port 1011 is connected with the outside world. Through the baffle plate 802, when there is no need to dissipate heat inside the reactive compensation cabinet body 1, the heat dissipation port 1011 can be covered by the baffle plate 802 to prevent external dust from entering the reactive compensation cabinet body 1 through the first filter 103, and also to prevent some small insects from biting the first filter 103.

[0068] In this embodiment, the opening and closing mechanism 8 also includes an extrusion component 801, which includes an upper hinge seat 8011 and a lower hinge seat 8017. The upper hinge seat 8011 is fixedly installed on the inner side of the rain cover 102, and the lower hinge seat 8017 is fixedly connected to the side of the shielding plate 802 away from the heat dissipation port 1011.

[0069] By adopting the above-mentioned technical scheme, when the reactive compensation cabinet body 1 does not need to dissipate heat, the baffle plate 802 can be forcibly squeezed through the extrusion component 801 to ensure that the baffle plate 802 can completely cover the heat dissipation port 1011; when the reactive compensation cabinet body 1 is dissipating heat, the air pressure entering the reactive compensation cabinet body 1 can lift the baffle plate 802 to connect the heat dissipation port 1011 with the outside world; at this time, under the blowing of air pressure, external dust cannot enter the reactive compensation cabinet body 1 through the first filter 103, and some impurities and insects cannot adhere to the first filter 103.

[0070] Specifically, in this embodiment, a mounting groove 204 is opened on one side of the assembly box 2, and the air inlet 203 is located inside the mounting groove 204. A second filter 205 for preliminary filtering of the external air is fixedly installed on the mounting groove 204. The second filter 205 can be used to perform preliminary filtering of the external air to prevent large particles of impurities such as leaves from entering the blower 301.

[0071] In this embodiment, in order to prevent the second filter screen 205 from being blocked, an anti-blocking mechanism 9 is provided inside the assembly box 2 to prevent the second filter screen 205 from being blocked. The anti-blocking mechanism 9 includes a motor 901, a screw rod 902, a high-pressure air knife 904 and a guide rod 907.

The other end of the high-pressure air knife 904 is fixedly connected to a sliding sleeve 906, and the sliding sleeve 906 is slidably sleeved on the guide rod 907. The jet direction of the high-pressure air knife 904 is toward the second filter screen 205. A fourth three-way valve 305 is installed at the air outlet of the blower 301, and one of the air outlets of the fourth three-way valve 305 is connected to one end of the first ventilation pipe 302. The other air outlet of the fourth three-way valve 305 is connected to the second ventilation pipe 306, and one end of the second ventilation pipe 306 away from the fourth three-way valve 305 is connected to the air inlet of the high-pressure air knife 904. A pressure sensor 206 is fixedly installed inside the assembly box 2, and the pressure sensor 206 is electrically connected to the signal input end of the PLC controller. The motor 1 901 and the fourth three-way valve 305 are both controlled by the PLC controller. When the pressure sensor 206 detects that the pressure inside the assembly box 2 is lower than the set value, the PLC The controller controls the blower 301 and the motor 901 to start, and controls the fourth three-way valve 305 to connect the air outlet of the blower 301 with the second ventilation pipe 306. The wind blown by the blower 301 is blown from the high-pressure air knife 904 to the second filter 205 to clear the blockage of the second filter 205. At the same time, the PLC controller controls the forward or reverse rotation of the rotating shaft of the motor 901, and then the screw rod 902 drives the high-pressure air knife 904 to move up and down, so as to fully clear the blockage of the second filter 205.

[0072] Among them, in order to cooperate with the anti-blocking mechanism 9 to further improve the clearing effect of the second filter 205, a knocking device 11 is also fixedly installed on the high-pressure air knife 904. The knocking device 11 is provided with several groups, which are used to knock the second filter 205 with blocked meshes to force the foreign matter blocked by the meshes of the second filter 205 to be knocked off. Each group of the knocking device 11 includes a motor 1101 fixedly installed on the upper part of the high-pressure air knife 904, a disc 1102 fixedly installed on the output shaft of the motor 1101, a nylon rope 1103 fixedly installed on the disc 1102, and spherical rubber blocks 1104 fixedly installed at both ends of the nylon rope 1103. When working, Motor 2 1101 drives disc 1102 to rotate, and disc 1102 drives nylon rope 1103 to rotate. Nylon rope 1103 drives spherical rubber blocks 1104 at both ends to continuously knock the second filter 205, so that foreign objects blocked by the mesh are knocked off, and at the same time, the high-pressure wind knife 904 is used to blow the knocked-off foreign objects to the outside of the assembly box 2. Since the second filter 205 is located at the air inlet of the assembly box 2, the outer side of the second filter 205 is more easily blocked by foreign objects. Therefore, the high-pressure wind knife 904 can blow the knocked-off foreign objects to the outside of the assembly box 2, thereby improving the clearing effect of the second filter 205.

[0073] In this embodiment, the lower ends of one side of the two filtering areas are connected to a sewage pipe 404, and a sewage valve 4041 is installed on the sewage pipe 404.

The liquid level sensor 403 located at the upper end is used to measure whether the water level inside the filtering area is too high, and the liquid level sensor 403 located at the lower end is used to measure whether the water level inside the filtering area is too low. The liquid level sensor 403 is electrically connected to the signal input end of the PLC controller. The sewage in the filtering mechanism 4 can be discharged through the sewage pipe 404 and the sewage valve 4041. Clean water can be added to the water storage tank 401 through the water inlet pipe 405 and the water inlet valve 4051. The water level situation in the filtering mechanism 4 can be understood in real time through the liquid level sensor 403.

The cooling surface of the semiconductor refrigeration sheet 406 is arranged inside the filter area, and the heating surface of the semiconductor refrigeration sheet 406 is arranged outside. The semiconductor refrigeration sheet 406 is controlled by a PLC controller. By adopting the above technical scheme, when the heat dissipation effect of using external natural air is not good, the semiconductor refrigeration sheet 406 can be started to cool the water inside the water tank 401, and then the air passing into the water tank 401 can be cooled, and then the cooled air is separated from the water vapor and passed into the reactive compensation cabinet body 1 to ensure the normal operation of the heat dissipation work.

[0075] In this embodiment, in order to prevent the dust inside the water tank 401 from being deposited at the bottom of the water tank 401 and being inconvenient for subsequent discharge, a space is left between the bottom of the second air distribution pipe 304 and the inner bottom of the filtration area, and the nozzle on the second air distribution pipe 304 sprays air toward the bottom of the filtration area. Through this arrangement, the bottom of the water tank 401 can be continuously impacted by the introduced gas, thereby blowing away the dust accumulated at the bottom of the water tank 401 and preventing it from agglomerating.
