Problems solved by technology

Since there is no temperature and humidity monitoring module in the outdoor terminal box, the operation and maintenance personnel generally follow the regulations of Wutong and the maintenance plan in the station. For normal work, the operation and maintenance personnel need to check the working conditions of the dehumidifiers one by one for many times. This work needs to open each box one by one for checking, and the faulty dehumidifier cannot be found in time; for the dehumidifier that cannot operate normally, it needs to be replaced. When the terminal box needs to be opened for a long time, the humid air enters the terminal box and affects the equipment in the terminal box.

Embodiment 1

[0030] Such as Figure 1-5 Shown is the first embodiment of the present invention, an outdoor terminal box 1 temperature and humidity control platform, such as figure 1 shown, including:

[0031] The outdoor terminal box 1 is equipped with a heating dehumidifier 2 inside the outdoor terminal box 1, such as image 3 As shown, the heating dehumidifier 2 is fixedly installed on the mounting plate 3, the mounting plate 3 is a cuboid plate-shaped structure, a mounting hole 19 is cut out on the side wall of the outdoor terminal box 1 by a cutting machine, and the mounting plate 3 is detachable through the connecting component It is connected outside the outdoor terminal box 1, and the heating dehumidifier 2 is located in the outdoor terminal box 1 through the installation hole 19 at this time.

[0032] The structure of the connected component is as Figure 4 As shown, the connection assembly includes a stud 8, and the bottom end of the stud 8 is rotated to set a rotating block 9....

Embodiment 2

[0038] Such as Figure 5 Shown is the second embodiment of the present invention. The difference between this embodiment and Embodiment 1 is that a torsion spring 16 is arranged between the rotating shaft 15 and the rotating block 9, and one end of the torsion spring 16 is statically connected to the rotating shaft 15, and the other end of the torsion spring 16 is One end is statically connected to the rotating block 9 (not marked in the figure), when the rotating block 9 is not in contact with the stud 8, the angle between the rotating block 9 and the stud 8 is 0, which facilitates the insertion of the stud 8 into the through hole; When the stud 8 is taken out in the through hole, the bolt 11 is first screwed on. During the screwing process of the bolt 11, under the action of the torsion spring 16, the rotating block 9 automatically rotates from a position perpendicular to the stud 8 to the position aligned with the stud 8. The position where the angle is 0 facilitates the ex...

Embodiment 3

[0040] Such as Figure 6 Shown is the third embodiment of the present invention, the difference between this embodiment and the first embodiment is that the size of the limiting ring 20 is the same as that of the nut 10, the area of ​​the top of the bolt 11 is smaller than the limiting ring 20, and the size of the limiting ring 20 Holes are all drilled at the six corners, and when the nut 10 is screwed, two pointed ends of the snap ring pliers can be inserted into the through holes to fix the stud 8.

Abstract

The invention discloses a temperature and humidity control platform for an outdoor terminal box, comprising: an outdoor terminal box, a heating dehumidifier is arranged in the outdoor terminal box, the heating dehumidifier is arranged on a mounting plate, and the mounting plate can be connected through a connecting component. Disassemble and connect outside the outdoor terminal box; wireless temperature and humidity collector, the wireless temperature and humidity collector is located in the outdoor terminal box, used to collect the temperature and humidity in the outdoor terminal box; signal repeater, the signal repeater is used It is used to receive and integrate the temperature and humidity signals sent by the wireless temperature and humidity collector; the remote server is used to receive the temperature and humidity signals sent by the signal repeater and convert them into data signals; the monitoring host uses Based on receiving the data signal sent by the remote server and displaying the temperature and humidity data, the present invention can find and replace the faulty dehumidifier in time, without opening the box door when the faulty dehumidifier is replaced, ensuring the normal operation of the equipment inside the terminal box.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an outdoor terminal box temperature and humidity control platform. Background technique [0002] The substation terminal box is the intermediate link between outdoor electrical equipment and indoor measurement and control, protection, communication and other equipment, and is generally installed next to the equipment. When the air is humid, especially in the rainy season, moisture and condensation in the outdoor switch terminal box will easily lead to a decrease in the insulation resistance of the DC secondary circuit to the ground. In severe cases, the insulation resistance will drop to zero, thereby forming a DC positive or negative power supply. . If the two points of DC are grounded, the DC fuse will be blown, the protection will refuse to operate or malfunction, and even damage the equipment, seriously threatening the safe operation of the power grid. If the ter...
