[0002] Box-type substation is a kind of power distribution equipment. In humid weather, since box-type substation is generally installed in outdoor environment, if the air in the high-voltage room of the box-type substation is directly connected to the outside, the high-humidity air outside will flow directly into the high-voltage room, causing the humidity in the high-voltage room to increase, affecting the safe operation of electrical equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0068] See also Figures 1 to 13 , an intelligent environment monitoring system for a high-voltage room of a substation provided in an embodiment of the present application comprises: a support component 1 and a monitoring component 2;

[0069] The support assembly 1 includes: a high-voltage chamber 11, a chamber door 12 and a first return plate 13. Among them, multiple high-voltage chambers 11 are arranged in a body according to a certain wiring scheme to form a substation. An installation cavity 14 is arranged inside the high-voltage chamber 11; an opening 15 connected to the installation cavity 14 is arranged on the front face of the high-voltage chamber 11; the chamber door 12 can be flipped and arranged on the opening 16 to control the opening and closing of the opening 15; the first return plate 13 is arranged on the opening 15, and the outer periphery is in contact with the wall surface of the opening 15. Through the first return plate 13, the chamber door 12 can be abutted when the chamber door 12 is closed, so as to play the role of closing the opening 15.

[0070] The monitoring component 2 includes: a return pipe 21, a flexible hose 22, a monitoring box 23, a humidity sensor 24, an air pump 25, a heating wire 26, and a controller (not shown in the figure); the return pipe 21 is arranged on the inner circumference of the first return plate 13, and a first solenoid valve 211 communicating with the inside of the pipe is arranged on the return pipe 21; the flexible hose 22 is arranged in the installation cavity 14, and a second solenoid valve 221 communicating with the inside of the pipe is arranged on the flexible hose 22; the monitoring box 23 is arranged in the installation cavity 14; the air pump 25, the controller, the heating wire 26, and the humidity sensor 24 are all arranged in the monitoring box 23; the air pump 25 is connected to the flexible hose 22 and the return pipe 21 through an air pipe 251, and the air pump 25 is connected to the inside of the monitoring box through an air port 251; the controller is electrically connected to the heating wire 26, the air pump 25, the humidity sensor 24, the first solenoid valve 211, and the second solenoid valve 221.

[0071] Specifically, both the first return plate 13 and the return pipe 21 are in a return shape; moreover, a plurality of first solenoid valves 211 can be arranged around the inner circumference of the return pipe 21, so that gases at multiple positions on the inner circumference of the opening 15 can be collected, improving the uniformity of detection. The controller can be arranged in the monitoring box 23 or independently arranged outside the support component 1. The controller is used to control the humidity sensor 24 to detect the humidity values at different positions in the high-pressure chamber 11 by controlling the opening and closing of the first solenoid valve 211 and the second solenoid valve 221. During detection, the controller can control the air pump 25 to suck air, so that the gas at the opened first solenoid valve 211 or second solenoid valve 221 will be sucked into the air pump 25 and discharged into the monitoring box 23 through the air port 251, and the humidity sensor 24 will perform humidity detection to obtain the humidity value. When the humidity value exceeds the preset humidity value, the controller can control the heating wire 26 to start, heating the gas inside the monitoring box 23 to protect the electrical components inside the monitoring box 23.

[0072] In a further improved embodiment, please refer to Figures 1 to 12 , a ventilation opening 17 communicating with the installation cavity 14 is arranged on the side end face of the high-pressure chamber 11; the monitoring component 2 further includes: a ventilation pipe 27; the ventilation pipe 27 is adapted to the shape of the ventilation opening 17, and the ventilation pipe 27 is arranged in the installation cavity 14 corresponding to the position of the ventilation opening 17; the ventilation pipe 27 is connected to the air pipe, and a third solenoid valve 271 communicating with the inside of the pipe is arranged on the ventilation pipe 27; the controller is electrically connected to the third solenoid valve 271.

[0073] By arranging the ventilation opening 17 on the side end face of the high-pressure chamber 11, it is beneficial for the high-pressure chamber 11 to ventilate and dissipate heat. At the same time, through the ventilation pipe 27, when the third solenoid valve 271 is opened, the humidity sensor 24 can collect the humidity at the position of the ventilation opening 17. Among them, the ventilation pipe 27 can be in a mesh shape. Correspondingly, the ventilation opening 17 is in a four-square shape. Correspondingly, a support plate 19 is also arranged in the high-pressure chamber 11. The support plate 19 is clamped with the inner wall of the high-pressure chamber 11 and is used for installing the ventilation pipe 27.

[0074] Furthermore, it also includes a blocking component 3; the blocking component 3 includes: a first elastic tube 31; the ventilation tube 27 is arranged in the first elastic tube 31 and is connected to the interior of the first elastic tube 31; the third solenoid valve 271 extends out of the first elastic tube 31; the controller is used to receive the humidity value detected by the humidity sensor 24, and is also used to control the air pump 25 to blow air into the air pipe 251 when the humidity value exceeds the preset humidity value, so that the first elastic tube 31 expands to block the vent 17.

[0075] When the humidity value exceeds the preset humidity value, it indicates that the humidity of the external air is too high. The first elastic tube 31 expands to block the vent 17 to prevent external air from entering the high-pressure chamber 11 .

[0076] Furthermore, the blocking assembly 3 further includes: a second elastic tube 32 and a second return plate 33; the second return plate 33 is arranged in the first return plate 13, and the outer periphery is in contact with the inner periphery of the first return plate 13; a return groove 322 is provided on the front end surface of the second return plate 33; the second elastic tube 32 is arranged in the return groove 322; the return tube 33 is arranged in the second elastic tube 32, and is communicated with the inside of the second elastic tube 32; the first solenoid valve 211 extends out of the second elastic tube 32; the controller is also used to control the air pump 25 to blow air into the air pipe when the humidity value exceeds the preset humidity value, so that the second elastic tube 32 expands and abuts against the chamber door. In addition, an air gap 321 is formed between the second elastic tube 32 and the return tube 21. The return tube 21 is communicated with the air gap 321.

[0077] Similarly, the second elastic tube 32 cooperates with the air pipe 251, when the humidity value exceeds the preset humidity value, it indicates that the humidity of the external air is too high, and the second elastic tube 32 can abut against the inner wall of the chamber door 12 to prevent the external air from entering the high-pressure chamber 11 through the gap between the chamber door 12 and the first return plate 13. It should be noted that the first return plate 13, the second return plate 33 and the return tube 33 are all in the shape of a Chinese character "Yu", and correspondingly, the second elastic tube 32 is also in the shape of a Chinese character "Yu".

[0078] Furthermore, the front end surface of the first return plate 13 protrudes forward than the front end surface of the second return plate 33. Thus, the second elastic tube 32 does not abut against the chamber door 12 when it is not expanded. After the second elastic tube 32 expands, it abuts against the chamber door 12 to form a sealing layer.

[0079] Furthermore, the monitoring assembly 2 further includes: a rain sensor; the rain sensor is arranged on the top of the high-pressure chamber 11. The controller is electrically connected to the rain sensor, and can sense whether it is raining outside through the rain sensor, so as to blow air into the first elastic tube 31 and the second elastic tube 32 in advance through the air pump 25 to expand the two.

[0080] For further information, see Figure 7 A partition 231 is provided in the monitoring box 23; the partition 231 divides the monitoring box 23 into an upper chamber and a lower chamber, and a through hole 232 connecting the upper chamber and the lower chamber is provided on the partition 23; a through hole 233 connecting the upper chamber is provided on the top of the monitoring box 12; the humidity sensor 24 is provided in the upper chamber; the air pump 25 and the heating wire 26 are provided in the lower chamber.

[0081] The monitoring box 23 is divided into an upper chamber and a lower chamber by the partition 231. When the air pump 25 discharges air through the air port 252, the gas will flow from the lower chamber to the upper chamber for detection by the humidity sensor 24. When the heating wire 26 is started, the heated gas will also flow from the lower chamber to the upper chamber, and then the gas will flow away from the perforation 233 to prevent the electrical components inside the monitoring box 23 from getting wet.

[0082] For further information, see Fig.11 A hook 18 for the hose 22 to be hung is provided in the installation cavity 14. When the staff opens the door 12 for maintenance, the hose 22 can be hung on the hook 18 to avoid interference with the maintenance work.

[0083] The second aspect of the present application provides an intelligent environment monitoring method for a high-voltage room 11 of a substation, which is applied to the above-mentioned intelligent environment monitoring system for a high-voltage room of a substation;

[0084] The method comprises the following steps:

[0085] S1, control the air pump 25 to suck air into the air pipe 251.

[0086] When the humidity in the high pressure chamber 11 is monitored, the air pump 33 is first controlled by the controller to suck air into the air pipe 251 .

[0087] S2. Control the first solenoid valve 211, the second solenoid valve 221 and the third solenoid valve 271 in sequence according to a preset order and a preset time interval to open for a preset time and then close, and collect the humidity values ​​of the gases collected by the first solenoid valve 211, the second solenoid valve 221 and the third solenoid valve 271 detected by the humidity sensor 24 in sequence, wherein the preset time length is less than or equal to the preset time interval.

[0088] Afterwards, the controller monitors and controls the opening of the first solenoid valve 211, the second solenoid valve 221, and the third solenoid valve 271 in a preset order and a preset time to avoid the three solenoid valves being opened at the same time, causing the absorbed gases to interfere with each other and affect the accuracy of humidity detection. Among them, the preset time interval and the preset duration can both be three minutes. The preset order can be to open the first solenoid valve 211 first, then open the second solenoid valve 221, and finally open the third solenoid valve 271.

[0089] When the first solenoid valve 211 is opened, the gas at the position of the return tube 21 is sucked into the air pipe 251, and then sucked into the monitoring box 23 for humidity detection. Three minutes after the first solenoid valve 211 is opened, the first solenoid valve 211 is closed and the second solenoid valve 221 is opened. During the time when the second solenoid valve 221 is opened, the gas sucked by the second solenoid valve 221 gradually replaces the gas in the air pipe 251, and then the replaced gas is measured by the humidity sensor 24, so that the gas humidity at the position of the hose 22 can be measured more accurately. Three minutes after the second solenoid valve 221 is opened, it is closed, and the third solenoid valve 271 is opened, and the cycle is repeated in sequence, so that the controller can obtain the air humidity at multiple positions in the high-pressure chamber 11, thereby improving the monitoring accuracy. After the third solenoid valve 271 is opened and closed, after a second preset time, such as half an hour, it can return to step S2 and perform a second gas collection.

[0090] When it rains outside, the gas mixed with rainwater will first flow into the high-pressure chamber 11 through the vent 17 and the gap between the chamber door 12 and the high-pressure chamber 11. At this time, the first solenoid valve 211 and the second solenoid valve 221 can immediately suck the air containing rainwater into the humidity sensor 23 for measurement, and obtain the gas humidity. Compared with the substation in the prior art in which only the humidity sensor is installed on the side wall of the high-pressure chamber 11, the gas humidity can only be measured after the gas mixed with rainwater has floated to the humidity sensor position in the high-pressure chamber 11. However, at this time, more moisture has entered the substation, thereby increasing the humidity in the high-pressure chamber 11.

[0091] At the same time, a rain sensor is provided on the top of the high-pressure chamber 11. When the humidity sensor 24 measures that the humidity of the gas at the outlet of the opening 15 and the vent 17 is significantly increased, or the rain sensor detects rain, the controller first controls all solenoid valves to close, and controls the air pump 25 to stop working, and then controls the air pump 25 to blow air into the air pipe 251. During the blowing process of the air pump 25, the gas above the monitoring box 23 will enter the upper cavity of the partition 23 through the perforation 233, and then enter the lower cavity through the through hole 232, and enter the air pump 25 through the air port 252, and then blow into the circular tube 21, the ventilation tube 27 and the hose 22 through the air pipe 251. After that, the gas blows the first elastic tube 31 and the second elastic tube 32 to expand the two, so as to prevent excessive moisture or rainwater from entering the high-pressure chamber 11.

[0092] When the air pump 25 blows gas into the first elastic tube 31 and the second elastic tube 32, and the two expand, the controller controls the first solenoid valve 211 and the third solenoid valve 271 to open, and the gas output of the opened solenoid valves is less than the gas blowing volume of the air pump 25. In this process, the first elastic tube 31 and the second elastic tube 32 are in an expanded state, so that the gas in the loop tube 21 and the ventilation tube 27 cannot be discharged and the gas circulation cannot be formed, thereby causing the air pump 25 to be unable to continuously blow gas into the first elastic tube 31 and the second elastic tube 32.

[0093] At the same time, since the gas blown out by the air pump 25 is the gas in the high-pressure chamber 11, the humidity sensor 24 can measure the humidity of the gas flowing into the monitoring box 23. If the humidity of the gas measured by the humidity sensor 24 is too high, the controller controls the heating wire 26 to work. During the operation of the heating wire 26, the gas can be dried to prevent the humidity in the gas from being too high and affecting the electrical components.

[0094] When the rain outside stops and the humidity in the high-pressure chamber 11 is in a normal state, the controller controls the air pump 25 to stop blowing and controls all the solenoid valves to close. At this time, the first elastic tube 31 and the second elastic tube 32 return to their initial states. Then the controller controls the air pump 25 to inhale air and controls the solenoid valves to open and close in sequence, so that humidity monitoring can be carried out.

[0095] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein.
