[0002] The distribution cabinet is an important device for distributing electrical energy in the power system. It is responsible for receiving electrical energy from the upper power supply and distributing it reasonably to various electrical equipment or lower-level distribution devices.

[0003] For outdoor distribution cabinets in flood-prone areas, if water enters the cabinet during a flood, it can cause internal damage, leading to power outages in the area. To maintain normal power distribution during a flood, remote real-time monitoring of the distribution cabinet environment is required.

[0004] For example, the remote detection and control system for distribution cabinets recorded in the invention CN201810462157.4, the existing remote detection and control system for distribution cabinets does not dynamically adjust the state of the distribution cabinet according to the flood conditions outside the distribution cabinet and the current conditions inside the distribution cabinet when performing remote detection on the distribution cabinet. As a result, when the external flood and the current inside the distribution cabinet change, the state adjustment cannot be made in time, and the normal working state inside the distribution cabinet cannot be maintained by switching between different states. Therefore, a method and device are needed that can intelligently control and adjust the state of the distribution cabinet when changes in the external and internal environments are detected, so that the control distribution cabinet can make different working adjustments according to different flood depth environments. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a remote detection intelligent control method and device for a power distribution cabinet.

[0006] In a first aspect, the present invention provides a remote detection intelligent control method for a power distribution cabinet, comprising the following steps:

According to the real-time detected water accumulation information, the control unit controls the sealing system to adjust the corresponding sealing height H, so that when the sealing system is adjusted to the sealing height H, it can block the external water accumulation, so that the external water accumulation will not enter the interior of the distribution cabinet body after being blocked by the sealing system. The sealing system for blocking the water accumulation is adjusted according to the detected water accumulation information, which is beneficial for the distribution cabinet body to block the water accumulation through the sealing system, so that the water accumulation will not directly enter the interior of the distribution cabinet body, so that the equipment inside the distribution cabinet body can work normally, which is beneficial for the distribution cabinet body to work normally for power distribution;

[0067] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0068] like Figure 1 A remote detection intelligent control method for a power distribution cabinet is shown, comprising the following steps:

[0069] Step A1: The control unit obtains water accumulation information of the water accumulation outside the power distribution cabinet body 1, and controls the sealing height H of the sealing system inside the power distribution cabinet body 1 according to the water accumulation information to form a ventilation area S;

[0070] Step A2: The control unit obtains the current change flowing inside the power distribution cabinet body 1 to generate current information I, and controls the cooling unit to adjust the ventilation speed V through the ventilation area S according to the current information I and the ventilation area S;

[0071] Step A3: The control unit obtains temperature information inside and outside the power distribution cabinet body 1, and controls the cooling unit inside the power distribution cabinet body 1 to switch between air cooling and water cooling according to the temperature information and water accumulation information;

[0072] Step A4: The control unit obtains humidity information outside the power distribution cabinet body 1, and when the ventilation area S is formed, controls the drying system inside the ventilation area S to run or stop according to the humidity information;

[0073] For outdoor distribution cabinets in flood-prone areas, if water enters the cabinet during a flood, it can cause internal damage, leading to power outages in the area. To maintain normal power distribution during a flood, remote real-time monitoring of the distribution cabinet environment is required.

[0074] The existing remote detection and control system for distribution cabinets does not dynamically adjust the state of the distribution cabinet according to the flood conditions outside the distribution cabinet and the current conditions inside the distribution cabinet when performing remote detection on the distribution cabinet. As a result, when the external flood and the current inside the distribution cabinet change, the state adjustment cannot be carried out in time, and the normal working state of the distribution cabinet cannot be maintained by switching between different states. Therefore, a method and device are needed that can intelligently control and adjust the state of the distribution cabinet when changes in the external and internal environments are detected, so that the control distribution cabinet can make different working adjustments according to different flood depth environments;

[0075] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: when a flood occurs and water accumulates in the environment, the control unit obtains water accumulation information of the water accumulation outside the distribution cabinet body 1. According to the real-time detected water accumulation information, the control unit controls the sealing system to adjust the corresponding sealing height H, so that when the sealing system is adjusted to the sealing height H, it can block the external water accumulation, so that the external water accumulation will not enter the interior of the distribution cabinet body 1 after being blocked by the sealing system. The sealing system for blocking the water accumulation is adjusted according to the detected water accumulation information, which is beneficial for the distribution cabinet body 1 to block the water accumulation through the sealing system, so that the water accumulation will not directly enter the interior of the distribution cabinet body 1, so that the equipment inside the distribution cabinet body 1 can work normally, which is beneficial for the distribution cabinet body 1 to work normally and distribute power;

[0076] When the sealing system blocks the distribution cabinet body 1, the area above the sealing system through which air can pass is the ventilation area S. When the sealing height of the sealing system increases, the area of the ventilation area S decreases.

[0077] When the power distribution cabinet body 1 performs normal power distribution, the control unit obtains current information I for detecting current changes inside the power distribution cabinet body 1, and generates a ventilation speed V based on the current information I and the ventilation area S. The ventilation speed V is the flow speed of the airflow passing through the ventilation area S during ventilation. When the current in the current information I increases, the heat generated by the equipment increases. At this time, the ventilation speed is increased. When the ventilation area S decreases, the area that can be ventilated decreases. At this time, the ventilation speed is increased, which is conducive to maintaining the cooling efficiency inside the power distribution cabinet body 1 and is conducive to the power distribution cabinet body 1 performing normal power distribution.

[0078] The control unit obtains the internal and external temperatures of the power distribution cabinet body 1. When the indoor temperature is higher than the outdoor temperature, it can drive the airflow so that the low-temperature outdoor air flows through the interior of the power distribution cabinet body 1, so that the interior of the power distribution cabinet body 1 is air-cooled. When the indoor temperature is lower than the outdoor temperature, the cooling efficiency of air cooling is low. If the temperature of the accumulated water is lower than the indoor temperature, the control switches to water cooling, which is beneficial to cooling the interior of the power distribution cabinet body 1 through the accumulated water, thereby improving the cooling efficiency of the power distribution cabinet body 1, and thus facilitating normal power supply distribution of the power distribution cabinet body 1.

[0079] The control unit obtains the humidity information outside the distribution cabinet body 1. When the humidity outside the distribution cabinet body 1 is too high, when air cooling is used, the flowing airflow will drive the moisture in the external air into the interior of the distribution cabinet body 1, thereby causing the internal humidity of the distribution cabinet body 1 to increase, resulting in an increased risk of damage to the equipment inside the distribution cabinet body 1. At this time, the control unit controls the operation of the drying system, so that the drying system dries the airflow entering the interior of the distribution cabinet body 1, so that the interior of the distribution cabinet body 1 remains dry, which is conducive to the normal power distribution of the distribution cabinet body 1.

[0080] As an optional embodiment, step A1 specifically includes:

[0081] The control unit obtains the water depth information h and the water temperature information T detected by the water accumulation detection mechanism after water accumulates outside the power distribution cabinet body 1. The water accumulation information includes the water depth information h and the water temperature information T.

[0082] The control unit obtains a height difference value a from the input end;

[0083] The control unit substitutes the water depth information h into the calculation formula H=h+a to obtain the sealing height H. The space above the sealing height H of the sealing system forms the ventilation area S;

[0084] Send the sealing height H to the sealing system to control the start of the sealing system;

[0085] The water accumulation detection mechanism can detect the water depth and water temperature of external water accumulation in real time to generate water accumulation depth information h and water accumulation temperature information T. The water accumulation detection mechanism then sends the water accumulation depth information h and water accumulation temperature information T to the control unit, so that the control unit obtains the water accumulation depth information h and water accumulation temperature information T. The water accumulation information includes the water accumulation depth information h and water accumulation temperature information T, that is, the control unit obtains the water accumulation depth information h and water accumulation temperature information T when obtaining the water accumulation information. The staff can input the height difference a through the input end of the control unit;

[0086] It should be noted that the height difference a is adjusted by the staff according to needs. The height difference a is the difference between the sealing height of the sealing system and the height of the external water accumulation;

[0087] After the control unit obtains the height difference a from the input end, it puts the water depth information h and the height difference a into the calculation formula H=h+a, thereby obtaining the sealing height H=water depth information h+height difference a. After obtaining the sealing height H, since the maximum ventilation area of the sealing system is fixed, after removing the blocked area after the sealing system is adjusted to the sealing height H, the remaining ventilation area is the ventilation area S. The control unit then sends the sealing height H to the sealing system, so that the sealing system starts to adjust to the position corresponding to the sealing height H after receiving the sealing height H.

[0088] As an optional embodiment, step A2 specifically includes:

[0089] Step B1: The control unit obtains current information I from the power distribution cabinet body 1;

[0090] Step B2: The control unit obtains the current threshold information I0 and the maximum ventilation area S from the input terminal. max , adjustment coefficient b, basic ventilation speed v0;

[0091] Step B3: The control unit substitutes the current threshold information I0 and the current information I into the judgment formula I0≤I. If the judgment formula is met, the current information I, the current threshold information I0, and the maximum ventilation area S are substituted. max , ventilation area S is substituted into the calculation formula V=[v0*S max (I + b - I0)] / (b * S) to obtain the ventilation speed V;

[0092] Step B4: The control unit sends the ventilation speed V to the cooling unit to control the cooling unit to start;

[0093] The power distribution cabinet body 1 detects the current when distributing power, thereby obtaining current information I, and then the power distribution cabinet body 1 sends the current information I to the control unit, so that the control unit obtains the current information I;

[0094] The staff can input the current threshold information I0 through the input terminal;

[0095] It should be noted that the current threshold information I0 is a value set according to the actual situation when the current inside the distribution cabinet body 1 reaches the current threshold information I0. The heat generated by the current passing through the distribution cabinet body 1 cannot be naturally dissipated. At this time, if the heat inside the distribution cabinet body 1 is not dissipated, the temperature inside the distribution cabinet body 1 will gradually increase. The current threshold information I0 is a constant adjusted by the staff according to the different ambient temperatures and is a value set according to needs.

[0096] The staff can input the maximum ventilation area S from the input port max ;

[0097] It should be noted that the maximum ventilation area S max The maximum area of the distribution cabinet body 1 that can accommodate airflow when the sealing system is fully open is a constant that varies according to the distribution cabinet body 1. When the distribution cabinet body 1 is fixed, the maximum ventilation area S max is a fixed constant;

[0098] The staff can input the adjustment coefficient b from the input terminal;

[0099] It should be noted that the adjustment coefficient b is the current that increases with the current information I each time the ventilation speed V is doubled, so that the ventilation speed V doubles each time the current information I increases with the adjustment coefficient b. The adjustment coefficient b is a value set as needed.

[0100] The staff can input the basic ventilation speed v0 from the input terminal;

[0101] It should be noted that the basic ventilation speed v0 is the basic ventilation speed when the distribution cabinet body 1 starts to ventilate, that is, the ventilation speed set when the cooling unit starts to cool down when the current information I reaches the current threshold information I0. The basic ventilation speed v0 is a constant adjusted by the staff according to the different ambient temperatures and is a value set as needed;

[0102] The control unit can obtain the current threshold information I0 and the maximum ventilation area S from the input terminal. max , adjustment coefficient b, basic ventilation speed v0, the current threshold information I0 and the current information I are substituted into the judgment formula I0≤I. When the judgment formula is met, it means that the current information I is greater than the current threshold information I0. At this time, the cooling unit needs to be started to actively cool the interior of the power distribution cabinet body 1. Therefore, at this time, the control unit will substitute the current information I and the current threshold information I0, the maximum ventilation area S max , ventilation area S is substituted into the calculation formula V=[v0*S max (I + b - I0)] / (b * S) to obtain the ventilation speed V, and then the control unit sends the ventilation speed V to the cooling unit, so that the cooling unit starts to adjust to the ventilation driving speed corresponding to the ventilation speed V;

[0103] V=[v0*S maxThe setting of (I+b-I0)] / (b*S) makes the basic ventilation speed v0 doubled every time the current information I increases the adjustment coefficient b, and the basic ventilation speed v0 doubled every time the ventilation area S is reduced by half, and the two are superimposed on each other, so that the ventilation speed V can be adjusted and controlled according to the different detected environments, which is beneficial to the normal power supply distribution of the distribution cabinet body 1.

[0104] As an optional embodiment, the following steps can be added between step B3 and step B4:

[0105] The control unit obtains the speed threshold information V from the input terminal max ;

[0106] The control unit sends the speed threshold information V max Substitute the ventilation speed V into the judgment formula V≤V max If it does not meet the judgment formula, then the assignment formula V=V max Reassign the ventilation speed V;

[0107] When the current threshold information I0 and the current information I do not meet the judgment formula I0≤I, the control unit reassigns the ventilation speed V through the assignment formula V=V0;

[0108] The staff can input the speed threshold information V from the input terminal max ;

[0109] It should be noted that the speed threshold information V max The maximum ventilation speed of the cooling unit inside the power distribution cabinet body 1 when cooling, when the ventilation speed reaches the speed threshold information V max When it no longer increases, the speed threshold information V max It is a constant that the staff adjusts according to the different ambient temperatures and is a value that is set according to needs;

[0110] The control unit can obtain the speed threshold information V from the input end max Then the control unit will send the speed threshold information V max Substitute the ventilation speed V into the judgment formula V≤V max If it does not meet the judgment formula, it means that the ventilation speed V reaches the speed threshold information V max At this time, the ventilation speed V no longer increases, that is, the ventilation speed V is not affected by the calculation formula V=[v0*S max (I+b-I0)] / (b*S) setting, at this time the control unit passes V=V max The ventilation speed V is reassigned so that the ventilation speed V is maintained at the speed threshold information V maxIt remains unchanged, which helps to avoid the situation where the ventilation speed inside the power distribution cabinet body 1 is too high, causing damage to the equipment inside the power distribution cabinet body 1;

[0111] When the current threshold information I0 and the current information I do not meet the judgment formula I0≤I, it means that the current information I is less than the current threshold information I0. At this time, the heat generated by the current can be naturally ventilated and dissipated. At this time, if the internal temperature of the distribution cabinet body 1 is too high and the interior of the distribution cabinet body 1 needs to be cooled, the control unit will reassign the ventilation speed V through the assignment formula V=V0, so that the cooling unit maintains the basic ventilation speed v0 to cool it down, which is beneficial to avoid the situation where the internal temperature of the distribution cabinet body 1 is too high and the heat is not dissipated in time when the current information I is less than the current threshold information I0, resulting in damage to the internal equipment of the distribution cabinet body 1.

[0112] As an optional embodiment, step A3 specifically includes:

[0113] The control unit obtains outdoor temperature information T1 and indoor temperature information T2 from the temperature detection system;

[0114] The control unit obtains the first temperature threshold T from the input terminal min ;

[0115] The control unit sets the first temperature threshold T min Compare with the indoor temperature information T2, when T2<T min When T2≥T min When the control unit obtains the second temperature threshold T from the input terminal max ;

[0116] The control unit processes the outdoor temperature information T1, the indoor temperature information T2, and the second temperature threshold T max , the accumulated water temperature information T is compared. When T1<T2, the cooling unit is controlled to switch to air cooling. When T1≥T2 and T<T2, the cooling unit is controlled to switch to water cooling. When T1≥T2 and T≥T2, the cooling unit is controlled to switch to air cooling and the indoor temperature information T2 and the second temperature threshold T are compared. max Perform real-time comparison until T2≥T max When the power distribution cabinet main body 1 is controlled to suspend operation;

[0117] The temperature detection system can detect the temperature outside and inside the power distribution cabinet body 1 in real time to obtain outdoor temperature information T1 and indoor temperature information T2. The temperature detection system then sends the outdoor temperature information T1 and indoor temperature information T2 to the control unit so that the control unit obtains the outdoor temperature information T1 and indoor temperature information T2.

[0118] The staff can input the first temperature threshold T through the input terminal min ;

[0119] It should be noted that the first temperature threshold T min The temperature inside the power distribution cabinet body 1 when heat dissipation is required is lower than the first temperature threshold T min When the temperature inside the power distribution cabinet body 1 is 10000mA, the heat dissipation inside the power distribution cabinet body 1 can be eliminated by natural ventilation, and the equipment inside the power distribution cabinet body 1 will not be damaged. The first temperature threshold T min It is a constant that the staff adjusts according to the different ambient temperatures and is a value that is set according to needs;

[0120] The staff can input the second temperature threshold T through the input terminal max ;

[0121] It should be noted that the second temperature threshold T max The maximum temperature at which the power distribution cabinet body 1 can operate normally is the temperature inside the power distribution cabinet body 1 greater than the second temperature threshold T max When the power distribution cabinet body 1 cannot work normally, the power distribution cabinet body 1 will be damaged if it continues to work. The second temperature threshold T max It is a constant that the staff adjusts according to the difference of the power distribution cabinet body 1, and is a value set according to the needs;

[0122] The control unit obtains the first temperature threshold T from the input terminal. min , then the first temperature threshold T min Compare with the indoor temperature information T2, when T2<T min When the temperature inside the power distribution cabinet body 1 is lower than the threshold temperature for natural heat dissipation, there is no need to actively dissipate heat inside the power distribution cabinet body 1. At this time, the control unit controls the cooling unit to close. When T2≥T min When the temperature inside the power distribution cabinet body 1 is greater than or equal to the threshold temperature for natural heat dissipation, active heat dissipation of the inside of the power distribution cabinet body 1 is required. At this time, the control unit obtains the second temperature threshold T from the input end. max , and the outdoor temperature information T1 is combined with the indoor temperature information T2 and the second temperature threshold T max, and the accumulated water temperature information T. When T1<T2, that is, the internal temperature of the distribution cabinet body 1 is greater than the external temperature, the interior of the distribution cabinet body 1 can be cooled by air cooling. At this time, the control unit controls the cooling unit to switch to air cooling. When T1≥T2 and T<T2, that is, the internal temperature of the distribution cabinet body 1 is less than or equal to the external temperature, but the internal temperature of the distribution cabinet body 1 is greater than the accumulated water temperature. At this time, the interior of the distribution cabinet body 1 can be cooled by water cooling. At this time, the control unit controls the cooling unit to switch to water cooling. When T1≥T2 and T≥T2, the internal temperature of the distribution cabinet body 1 is less than or equal to the external temperature, and the internal temperature of the distribution cabinet body 1 is less than or equal to the accumulated water temperature. At this time, neither air cooling nor water cooling can fully cool the interior of the distribution cabinet body 1. However, air cooling is beneficial to drive airflow exchange, which is beneficial to suppressing the continuous increase in the temperature of the distribution cabinet body 1. Therefore, at this time, the control unit controls the cooling unit to switch to air cooling, and at the same time, the control unit controls the indoor temperature information T2 and the second temperature threshold T max Perform real-time comparison until T2≥T max When the temperature inside the distribution cabinet body 1 is greater than or equal to the maximum operating temperature of the distribution cabinet body 1, the control unit controls the distribution cabinet body 1 to suspend operation, thereby preventing the distribution cabinet body 1 from being damaged by continued operation.

When there is water accumulation outside, when the pressure of the accumulated water is applied to the first waterproof cover cloth 3, the first waterproof cover cloth 3 can be supported by the outer wall of the inner box body 2, thereby preventing the first waterproof cover cloth 3 from being deformed and collapsed under the action of the accumulated water pressure, thereby losing the effect of intercepting the accumulated water.

[0147] The driving mechanism can drive the movable platform 301 to move vertically, thereby driving the top edge of the first waterproof cover cloth 3 to move vertically through the movable platform 301, so that the first waterproof cover cloth 3 can adjust the interception height of the accumulated water by the vertical movement of the top edge, that is, the bottom of the first waterproof cover cloth 3 is fixed between the power distribution cabinet body 1 and the inner box body 2, and the first waterproof cover cloth 3 intercepts the accumulated water by being raised and lowered, so that the equipment inside the power distribution cabinet body 1 is wrapped inside the first waterproof cover cloth 3, which helps to prevent the accumulated water from entering the power distribution cabinet body 1 and causing damage to the equipment;

The setting of the one-way valve 705 allows the water to be discharged in one direction only, preventing the external accumulated water from entering the inside of the power distribution cabinet body 1 along the second plug-in pipe 704.

[0174] The working principle of the present invention is as follows: when a flood causes water accumulation in the environment, the control unit obtains water accumulation information of the water accumulation outside the distribution cabinet body 1. According to the real-time detected water accumulation information, the control unit controls the sealing system to adjust the corresponding sealing height H, so that when the sealing system is adjusted to the sealing height H, it can block the external water accumulation, so that the external water accumulation will not enter the interior of the distribution cabinet body 1 after being blocked by the sealing system. The sealing system for blocking the water accumulation is adjusted according to the detected water accumulation information, which is beneficial for the distribution cabinet body 1 to block the water accumulation through the sealing system, so that the water accumulation will not directly enter the interior of the distribution cabinet body 1, so that the equipment inside the distribution cabinet body 1 can work normally, which is beneficial for the distribution cabinet body 1 to work normally and distribute power;

[0175] When the distribution cabinet body 1 is performing normal power distribution, the control unit obtains the current information I for detecting the current changes inside the distribution cabinet body 1, and generates the ventilation speed V based on the current information I and the ventilation area S. The ventilation speed V is the flow speed of the airflow passing through the ventilation area S during ventilation, so that when the current in the current information I increases, the heat generated by the equipment increases. At this time, the ventilation speed is increased. When the ventilation area S decreases, the area that can be ventilated decreases. At this time, the ventilation speed is increased, which is beneficial to maintaining the cooling efficiency inside the distribution cabinet body 1 and is beneficial to the normal power distribution of the distribution cabinet body 1.
