The utility model provides a low tension cable feeder pillar operating mode adjusts alarm system on line, includes power module 1, operating mode information acquisition module 2, temperature/humidity control system 3, operating mode indicator 4, front end controller 5, 4G communication module 6, backstage server end 7, alarm management application software, as shown in figure 1: the working condition information acquisition module 2, the temperature/humidity adjusting system 3 and the working condition indicator 4 are all connected with the front-end controller 5, the front-end controller 5 is connected with the 4G communication module 6, and the 4G communication module 6 is connected with the background server 7 through the channel 8.
The working condition information acquisition module 2 comprises a temperature/humidity information acquisition unit 2.1 and an in-box joint contact resistance acquisition unit 2.2;
the temperature/humidity information acquisition unit 2.1 mainly completes measurement of the internal temperature of the cable branch box and the humidity inside and outside the box, the temperature/humidity information acquisition unit 2.1 comprises a temperature/humidity sensor, and the temperature/humidity sensor is an SHT11 type digital sensor capable of outputting a fully calibrated relative humidity and temperature value. The contact resistance acquisition unit 2.2 of the in-box tap is used for carrying out on-line detection on index parameters aiming at the condition that the tap corrosion is caused by condensation or other factors of the box body and the contact resistance is overlarge due to the overcurrent of the tap; the implementation scheme is that the bridge voltage difference is obtained by detecting a resistance type strain gauge of BF120 type, and the numerical value of tap contact resistance is indirectly obtained by using the bridge principle. Finally, the temperature/humidity and tap contact resistance detection signals are transmitted to the front-end controller 5.
The front-end controller 5 adopts a 32-bit singlechip with low power consumption, and the model is STM32F 407. The signal transmitted by the detection end is compared with a plurality of temperature/humidity values set by the STM32F407 singlechip, and the judgment of the temperature/humidity working condition and the tap corrosion state of the box body is completed according to a preset logic algorithm and a preset program. When the temperature/humidity detection value is larger than the set early warning value and smaller than the alarm value, and the duration is longer than the set value, such as: and (3) starting the temperature/humidity adjusting system 3 by the controller after 20 minutes to realize automatic adjustment of the temperature/humidity in the box body.
After the temperature/humidity adjusting system 3 is started to work for a long time, such as: and when the temperature/humidity detection value is still larger than the set early warning value and smaller than the alarm value within 150 minutes, the controller sends an early warning signal outwards. Similarly, when the detected value exceeds the set alarm value for a long time, the temperature/humidity adjusting system 3 is immediately started to work, and after the adjusting system works for a period of time, such as: and (3) if the detection value is between the set early warning value and the set alarm value, continuing to wait for the adjustment system to work for a period of time, such as: 60 minutes; if the detected value is still above the set early warning value, the controller sends out an alarm signal.
The on-line working condition adjustment alarm flow chart of the cable branch box is shown in fig. 2, and the basic idea is to prevent condensation in the box by destroying the condensation generating conditions in the box body. Based on the general rule that when the temperature in the branch box is higher than 55 ℃, the condensation phenomenon cannot occur, whether the contact resistance of the branch box is too large due to corrosion or other factors of the tap or the busbar is considered primarily at this time to influence the performance of the branch box, and the contact resistance is used as a first judgment condition. The contact resistance is too high due to corrosion or other factors, and shows a slow change process. Therefore, the front-end controller 5 can acquire the temperature/humidity value once every 2 min and the contact resistance value once every 30 min so as to obtain the basic data information of the working condition adjustment alarm of the cable branch box. And then, according to the control conditions and strategies, starting the corresponding temperature/humidity adjusting system 3 to achieve the purposes of active prevention of condensation in the box and dynamic adjustment of the temperature. The reliability of the operation of the terminal box is improved, the service life of the terminal box is prolonged, and the online dynamic adjustment and the working condition monitoring are realized.
The temperature/humidity adjusting system 3 adopts a design scheme of combining refrigeration and heating, and is mainly based on two reasons. First, the installation mode of the low-voltage cable branch box outdoors is generally divided into two categories, namely a suspension type or a floor type (a foundation pile arranged at a certain height above the ground). When the branch box normally works, when the internal temperature of the branch box is usually higher than the ambient temperature and the relative humidity is less than 75%, condensation cannot occur, and whether the internal temperature of the branch box exceeds an allowable value is the key point to consider; and condensation can only occur when the current flowing through the branch box is small (no load or light load) and the temperature in the box is lower than the dew point temperature. Therefore, the low-voltage cable branch box installed in the open air has extremely low probability of simultaneous occurrence of cooling and anti-condensation requirements. Secondly, a semiconductor refrigeration technology based on the Peltier effect principle is adopted, when direct current is conducted, the cold end of a refrigerating semiconductor thermocouple absorbs heat, the hot end of the refrigerating semiconductor thermocouple releases heat, and if a heat dissipation device is installed at the hot end, heat in a box can be output through the cold end, so that the refrigerating purpose is achieved; on the contrary, to realize the heating effect, only the direction of the current flowing through the semiconductor needs to be changed. Therefore, the semiconductor refrigerating sheet 3.1 with the model number of TEC-12704 is selected in consideration of the condition that the refrigerating power of the branch box is not more than 45W and the applicability of the working current/pressure.

The hose 3.5 and the drain valve 3.6 are connected to the outside of the branch box. Wherein, the radiating fins 3.2 and the radiating fan 3.3 are selected from a whole set of devices with the model number of XH-X166; the water pan 3.4 is made of 40X 5mm aluminum material with a discharge spout in the middle, and the drain valve 3.6 is CWX-15Q-CR 2-01.
When the temperature/humidity adjusting system 3 works in a refrigeration anti-condensation mode, the drain valve 3.6 is powered on, and the hose 3.5 is smooth in water channel; water vapor molecules in the branch box are condensed on the semiconductor refrigerating surface, the water molecules are gathered on the surface of the metal block to form water drops, the water drops slide to the water receiving tray by virtue of self gravity, and the water drops are led out of the cable branch box through the hose 3.5 and are discharged; on the contrary, the power supply positive and negative electrodes of the semiconductor refrigerating sheet 3.1 are changed, the temperature/humidity adjusting system 3 works in a heating and cooling mode, the drain valve 3.6 is powered off, the water channel of the hose 3.5 is blocked, and heat in the branch box is transferred to the cold end through the hot end of the semiconductor refrigerating sheet 3.1, so that the cooling effect is achieved.

The 4G communication module 6 is selected, and the situation that the field use environment of the branch box is complex and large interference exists in practice is considered, so that an isolation type RS485 chip ADM2587E is adopted. When the front-end controller 5 sends an alarm signal to the outside, the isolated RS485 chip ADM2587E is used as a communication bridge between the front-end controller 5 and the background server 7 to complete information transmission.
Because transmitted data does not contain I and II type safety data of the power system in information transmission, the background Server end 7 adopts a B/S (Browser/Server) structure and comprises an application Server and application software for 'low-voltage cable branch box supervision management'; the monitoring device is used for allowing managers to log in and check monitoring data of the low-voltage cable branch box. In the B/S structure, client software is not required to be installed, and a line manager can log in and check the line manager as long as a browser and a computer can surf the internet, so that the convenience of use of a user is ensured.
