In this way, when the rear door panel 3 is closed, the data processing device installation mechanism 4 and the data acquisition unit assembly mechanism 5 are in contact with each other. There is a certain distance between the structure 5 and the rear door panel 3 to facilitate air flow. The side panel 41 is installed on the front side of the load-bearing bottom plate 42. The side panel 41 is also movably connected to the support column 43 through a hinge. The support column 43 is fixedly installed on the inner wall of the box body 1. There are four support columns 43. A horizontal wiring rack 44 is installed on the support column 43. There are two wiring racks 44. The two wiring racks 44 are parallel to the load-bearing bottom plate 42. The two wiring racks 44 are respectively located above and below the load-bearing bottom plate 42.

The heat dissipation window panels 11 are detachable, and the bottom end of the heat dissipation window panels 11 is flush with the bottom end of the data processing device installation mechanism 4, wherein the data processing device installation mechanism 4 is used to install a data processing device. Due to the huge amount of data to be processed, the data processing device to be installed on the data processing device installation mechanism 4 has complex circuits and generates a lot of heat during operation. The heat dissipation window panels 11 on both sides of the data processing device installation mechanism 4 can be opened to facilitate heat dissipation. At the same time, the front door panel 2 and the rear door panel 3 are opened to make the data processing device installed on the data processing device installation mechanism 4 in a four-sided ventilation state to achieve the effect of rapid fanning and cooling. A heat dissipation mesh 24 and a dust-proof net 25 matched with the heat dissipation mesh 24 are provided on the side wall of the front door panel 2. A fan 31 is installed on the center line of the rear door panel 3. Of course, in order to improve air circulation and accelerate heat dissipation, the fan 31 can also be turned on.

The lower fan 31 is located between the data processing device installation mechanism 4 and the data acquisition unit assembly mechanism 5, and dissipates the heat generated by the data acquisition unit while assisting in dissipating the heat generated by the data processing device.

[0028] Since there are many power grid lines and the lines are frequently cut and changed, there are many abnormal phenomena. Therefore, it is necessary to collect many kinds of signals. Each signal needs to be processed by different chips and integrated circuits. For this purpose, six rows of guide rails and baffles 54 are installed at equal intervals. According to actual use requirements, corresponding data signal acquisition installation plates can be installed on each row of guide rails to assemble data acquisition units. Since the amount of collected information data is huge and the heat generated is large, the acquisition units of different detection signals are installed in layers, which can make the arrangement more reasonable, disperse the generated heat, and avoid heat accumulation and line burning. At the same time, a wire binding rack 6 is installed. The wire binding rack 6 is used to arrange the wiring of the data processing device and the data acquisition unit, so that the internal wiring is reasonable, more beautiful, and generates less heat, which is convenient for inspection and maintenance.

[0029] The data processing device is installed on the load-bearing base plate 42, and the support columns 43 at different positions support the overall structure and are used to install the wiring rack 44. The wiring rack 44 can be divided into a front wiring rack 44a and a rear wiring rack 44b. The side plate 41 is used to install control components connected to the data processing device, wherein the wiring is carried out through the front wiring rack 44a in the wiring rack 44, so that the signal line, control line and power line are neatly arranged and connected, reducing the large amount of heat generated by the cluttered lines and making the wiring clearer; similarly, the rear wiring rack 44b is also used for wiring, and the power line and signal line of the fan 31 are connected through the rear wiring rack 44b. Here, there is a distance difference of not less than 30 cm between the rear wiring rack 44b and the load-bearing base plate 42, and the wiring is carried out through the rear wiring rack 44b. Figure 2 And attached Figure 4 It can be clearly seen from the display that a large space is reserved between the data processing device installation mechanism 4 and the data acquisition unit assembly mechanism 5 and the rear door panel 3 in the closed state. Its functions include the following two points: first, the large space is convenient for the maintenance of the components installed inside; second, the internal space is increased, and the heat generated can be dissipated into the space without heat accumulation. The heat can then be dissipated by the fan 31 to achieve a good cooling effect.

[0030] To sum up: the data acquisition unit assembly mechanism 5 in the power grid equipment maintenance early warning device is used to collect various working signals in the line, and after processing the signal, transmit it to the data processing device installed on the data processing device installation mechanism 4 through the signal line arranged on the wire binding rack 6; after the data processing device analyzes and processes the signal, it will transmit the signal to the side panel 41 and the early warning light group 21 through the signal line laid on the front wiring rack 44a, and the data processing device can transmit the signal to the fan 31 through the power line and signal line laid on the rear wiring rack 44b; the internal wiring of the power grid equipment maintenance early warning device is reasonable, more beautiful and generates less heat, which is convenient for maintenance and repair; in the closed state, a large space is reserved between the rear door panel 3 and the components, which is convenient for maintenance of the components installed inside, increasing the internal space, and the generated heat can be dissipated into its space, and the heat will not accumulate. Then, the heat dissipation through the fan 31 can achieve a good cooling effect. The different installation positions of the fan 31 and the heat dissipation mesh 24 achieve the effect of air convection, ensure heat dissipation, and the overall heat dissipation effect is good.
