Background technique

The main function of the switchgear is to open and close, control and protect the electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. Since the switchgear controls the circuit opening and closing of the electrical equipment, the inside of the cabinet A large number of circuit switching devices are included, so when the circuit is connected, it is necessary for the relevant switching components to generate heat, so it is necessary to dissipate heat inside the cabinet to ensure the normal operation of the internal devices.

There are two main ways to dissipate heat inside the existing switchgear; the first is to use natural ventilation for heat dissipation and ventilation, the convection circulation between the inside and outside of the cabinet, and the use of natural wind to exchange heat for the equipment in the cabinet. To a certain extent, the temperature in the cabinet can be reduced, but the corresponding cabinet needs to be provided with ventilation holes, and the exchange of internal and external air will engulf the dust in the air and accumulate inside the cabinet. At the same time, the efficiency of natural heat dissipation is very limited;

The second is to use related electrical cooling equipment to dissipate heat. The more common types are fans, heat exchangers and air conditioners to control the temperature in the cabinet.

S3: Work Execution

S3.1: The control module calls the current K value and judges whether it is within the K _{+ 1} range. If K<17, the control module calls the fan I, fan II, fan III, fan IV and the heating module to work. The real-time monitoring of the temperature and humidity sensor will stop the heating work until K belongs to _K2 .

If K belongs to K ₁ , the control module calls fan II and fan IV together or separately calls semiconductor cooling module I to work for 15-30 minutes to stop.

If K>27, the control module calls fan Ⅰ, fan Ⅱ, fan Ⅲ, fan Ⅳ and semiconductor refrigeration module Ⅰ to work. At this time, the temperature and humidity sensor monitors in real time until K belongs to K ₁ and then stops working;

At the same time, judge whether the difference between the currently retrieved K value and the last recorded K value exceeds 50% of the last recorded K value. If the current K value exceeds 50% of the last recorded K value, but K belongs to K ₁ , then Mark this K value as an outlier K ₂ ,

S3.2: The control module retrieves the current L ₁ value and judges whether it is within the L interval. If L ₁ does not belong to L, the control module calls the electric push rod to work, and removes the cover plate covering the exhaust pipe. At the same time, the control module calls Fan I, Fan II, Fan III, and Fan IV to start working. At this time, the temperature and humidity sensors monitor in real time, and stop working until L ₁ belongs to L;

S3.3: If the abnormal value K ₂ is determined to be no less than 3 times continuously after collecting the K value, the control module will send the abnormal data to the console to raise a warning.

A method for automatic temperature control of an automatic temperature control switch cabinet, as shown in Figure 11, specifically includes the following steps,

S1: Determine the range of constant temperature and humidity values in the cabinet

Set the internal temperature and humidity of cabinet 1 to include a temperature boundary interval and an air humidity interval as the execution trigger value. The normal temperature interval is 17-27°C, denoted as K ₁ , and the air humidity interval is 40-65%, denoted as L ;

S2: Intermittently obtain the temperature and humidity values in the cabinet

Every 2h, the internal temperature and humidity values of the cabinet 1 are obtained by the temperature and humidity sensor 6, recorded and stored in the control module 3, the temperature value is recorded as K, and the humidity value is recorded as L ₁ ;

S3: Work Execution

S3.1: The control module 3 calls the current K value and judges whether it is within the K ₊₁ range. If K<17, the control module 3 calls the fan I5a, the fan II5b, the fan III5c, the fan IV5d and the heating module 15 To work, use fans I5a, fans II5b, fans III5c, and fans IV5d to circulate hot air to all corners of the cabinet body 1. At this time, the temperature and humidity sensor 6 monitors in real time until K belongs to _K1 , then stop the heating work. It can reduce the occurrence of condensation caused by low temperature inside the cabinet 1, and ensure the stable operation of the equipment.

If K belongs to K ₁ , the control module 3 calls the fan II 5b, fan IV 5d and semiconductor cooling module I to work for 15 minutes and then stops. Since K belongs to K ₁ , it means that the temperature inside the cabinet 1 is within the normal range, but In order to avoid the possible local heating caused by the heating of the components on the component mounting plate 4, short-term cooling measures can be implemented to disperse the heat to all corners of the cabinet 1 to maintain the consistency of the internal temperature of the cabinet 1, and at the same time It can ensure that the internal temperature is always in the normal temperature range, so that the cooling equipment does not need to run for a long time

If K>27, the control module 3 calls the fan I5a, fan II5b, fan III5c, fan IV5d and semiconductor refrigeration module I10 to work, and if necessary, the control module 3 can be used to call the electric push rod 8 to work to cover The cover plate 9 of the exhaust pipe 7 is removed, and the high-heat air inside the cabinet 1 is discharged. At this time, the temperature and humidity sensor 6 monitors in real time, and the cooling operation can be stopped until K belongs to K ₁ ;

At the same time, judge whether the difference between the currently retrieved K value and the last recorded K value exceeds 50% of the last recorded K value. If the current K value exceeds 50% of the last recorded K value, but K belongs to K ₁ , then In the daily power consumption process, there may be situations where the circuit is overloaded and overheated during the peak period of power consumption, resulting in rapid temperature rise. At this time, it is necessary to mark such situations, so this K value is marked as an abnormal value K ₂ ,

If K>27, mark the K value this time as an abnormal value K ₂ , and the control module 3 calls the semiconductor refrigeration module I10, the semiconductor refrigeration module II112, the first electric guide rail 111, and the fan I5a, fan II5b, and fan III5c at the same time , fans IV and 5d work at the same time, the semiconductor refrigeration module I10 cools down the interior of the cabinet 1 globally, the first electric guide rail 111 moves up and down with the semiconductor refrigeration module II112, and cools down the component mounting plate 4 during the movement process, At this moment, the temperature and humidity sensor 6 monitors in real time until K belongs to K _and then stops working;

S3.2: The control module 3 retrieves the current L ₁ value and judges whether it is within the L range. If L ₁ does not belong to L, it means that the air inside the cabinet 1 is extremely dry or humid. It will affect the switching elements. At this time, it is necessary to use the control module 3 to call the electric push rod 8 to work, and remove the cover plate 9 covering the exhaust tube 7. At the same time, the control module 3 calls the fan Ⅰ5a, fan Ⅱ5b, fan Ⅲ5c, fan Ⅳ5d starts to work and replaces the air inside and outside the cabinet 1 in a cycle. At this time, the temperature and humidity sensor 6 monitors in real time, and under the real-time monitoring of the temperature and humidity sensor 6, the control module 3 calls the fan Ⅰ5a, fan Ⅱ5b, fan Ⅲ5c, and fan Ⅳ5d to start working After 6 minutes, if the L ₁ value fails to enter the L interval or the change in the L ₁ value compared with the real-time monitoring humidity value of the temperature and humidity sensor 6 is less than 20% after the 6-minute ventilation process, it is possible at this time It is because the humidity of the outside air itself is too high or too dry, which will cause the exchanged air to always fail to reach the predetermined range, which will make the fans Ⅰ5a, fan Ⅱ5b, fan Ⅲ5c, and fan Ⅳ5d always in the working state, so monitor within a fixed time If the air humidity still cannot meet the requirements after ventilation, the control module 3 needs to call the integrated humidification and dehumidification module 16 to work together with the fans Ⅰ5a, Ⅱ5b, Ⅲ5c, and Ⅳ5d. The integrated humidification and dehumidification module 16 can Humidification or dehumidification treatment is carried out through the air in the exhaust cylinder 7, and the ventilation work can be stopped until L ₁ belongs to L;

S3.3: If the abnormal value K ₂ is determined to be no less than 3 times continuously after collecting the K value, it means that the power consumption has been overloaded for a long time. At this time, it will cause a great burden on the circuit facilities and the circuit safety caused by heat The hidden danger is extremely dangerous, so the control module 3 can send abnormal data to the console to raise a warning. If the abnormal value exceeds 5 times, the control module 3 will shut down the relevant electrical equipment, or selectively shut down under human intervention Part of the electrical equipment, in order to ensure the safety of equipment.
