Wherein, the temperature sensors include a first temperature sensor group, a second temperature sensor group and a third temperature sensor group, and the three temperature sensor groups are electrically connected with the micro control unit, and provide temperature data to the micro control unit. The micro control unit is electrically connected with the temperature adjustment module, the display module, the communication module and the storage module, and the micro control unit controls the operation of the temperature adjustment module, the display module, the communication module and the storage module according to the temperature sensor data.

As shown in FIG. 4 , FIG. 4 is a schematic diagram of the combined distribution of temperature sensors inside the power distribution cabinet and the cabinet body in this embodiment. The temperature sensors include a first temperature sensor group 21 , a second temperature sensor group 22 and a third temperature sensor group 23 . The first temperature sensor group 21 is arranged on the cabinet near the bottom surface of the cuboid cabinet, the third temperature sensor group 23 is arranged on the cabinet near the top of the cuboid cabinet, and the second temperature sensor group 22 is placed on the first Between the temperature sensor group 21 and the third temperature sensor group 23 . The three groups of temperature sensors arranged in this way can respectively monitor the specific temperature in the upper, middle and lower directions of the power distribution cabinet, improve the reliability of temperature monitoring, and avoid false alarms caused by local overheating. When it is too high, it can also give a targeted alarm, visually display the fault area, and improve the pertinence of maintenance. Of course, the arrangement of the three temperature sensor groups in this embodiment is only used to explain the concept of the present invention. In practical applications, the first temperature sensor group can be directly installed on the bottom of the power distribution cabinet, and the third temperature sensor group can be directly installed on the distribution cabinet. The top surface of the electric cabinet does not affect the advantages of the distribution cabinet of the present invention, and belongs to the protection scope of the distribution cabinet of the present invention. In practical applications, the three temperature sensor groups may include one or more temperature sensors to further improve the accuracy of temperature monitoring.
本发明配电柜的显示模块3包括标记正常、警告以及报警三种状态的三色背景灯，当配电柜的工作情况为对应状态时，显示模块3的背景灯为对应颜色。作为优选方案，在实际应用中，可以采用绿色、黄色以及红色背景灯标示正常、警告、报警三种状态。The display module 3 of the power distribution cabinet of the present invention includes a three-color background light marking three states of normal, warning and alarm. When the working condition of the power distribution cabinet is the corresponding state, the background light of the display module 3 is the corresponding color. As a preferred solution, in practical applications, green, yellow and red background lights can be used to indicate three states of normal, warning and alarm.
作为优选方案，为提高配电柜报警信息的实时、准确传输；同时将配电柜工作状态、内部温度等数据传递至外部终端进行数据的监控、分析，通信模块4可以设置为有线通信模块和/或无线通信模块。As a preferred solution, in order to improve the real-time and accurate transmission of the alarm information of the power distribution cabinet; at the same time, the data such as the working state of the power distribution cabinet and the internal temperature are transmitted to the external terminal for data monitoring and analysis. The communication module 4 can be set as a wired communication module and /or a wireless communication module.
为了避免配电柜内部温度过高，本发明配电柜的调温模块可以为空调或风扇或二者的组合。当然，为了降低能耗并且保证调温效果，在外部环境条件允许的前提下，优选地采用空调与降温风扇配合的方案。空调与降温风扇在微型控制单元的控制下，可以单独工作，也可以配合工作。如图2及图3所示，本实施例配电柜给出了一种优选的风扇分布方案。本实施例的配电柜的调温风扇设置于柜体上，柜体对应设置有避让孔，风扇安装于所述柜体避让孔内。风扇包括第一风扇51以及第二风扇52，如图2所示，第一风扇51设置于柜体靠近底面的位置，如图3所示，第二风扇52与第一风扇51斜对角设置于柜体靠近顶面的位置，第一风扇51为进气扇，第二风扇52为排气扇。一般来说，由于冷空气重于热空气，底部的空气温度会略低于顶部的空气温度，因此，将设置于柜体靠近底面的第一风扇51设置为进气扇，将冷空气抽入配电柜，将设置于柜体靠近顶面位置的第二风扇52设置为排气扇，将配电柜内部的热空气排出。斜对角设置的第一风扇51及第二风扇52使配电柜内的空气流通距离尽量最大化，通过气流带走配电柜内部的热量，提高降温效果。In order to prevent the internal temperature of the power distribution cabinet from being too high, the temperature regulation module of the power distribution cabinet of the present invention can be an air conditioner or a fan or a combination of both. Of course, in order to reduce energy consumption and ensure the effect of temperature adjustment, it is preferable to adopt the scheme of cooperating with air conditioners and cooling fans under the premise that external environmental conditions allow. The air conditioner and the cooling fan can work independently or in cooperation under the control of the micro control unit. As shown in FIG. 2 and FIG. 3 , the power distribution cabinet of this embodiment provides a preferred fan distribution scheme. The temperature-regulating fan of the power distribution cabinet in this embodiment is arranged on the cabinet body, and the cabinet body is correspondingly provided with avoidance holes, and the fan is installed in the avoidance holes of the cabinet body. The fan includes a first fan 51 and a second fan 52. As shown in FIG. 2, the first fan 51 is arranged at a position near the bottom of the cabinet. As shown in FIG. 3, the second fan 52 is arranged diagonally to the first fan 51. At a position close to the top surface of the cabinet, the first fan 51 is an intake fan, and the second fan 52 is an exhaust fan. Generally speaking, because cold air is heavier than hot air, the air temperature at the bottom will be slightly lower than the air temperature at the top. Therefore, the first fan 51 that is arranged on the cabinet near the bottom surface is set as an air intake fan, and the cold air is sucked in. For the power distribution cabinet, the second fan 52 disposed near the top surface of the cabinet body is set as an exhaust fan to discharge the hot air inside the power distribution cabinet. The first fan 51 and the second fan 52 arranged diagonally maximize the air circulation distance in the power distribution cabinet as much as possible, and the heat inside the power distribution cabinet is taken away by the air flow to improve the cooling effect.
