Various parameters in operation can be displayed by measuring instruments, and certain electrical parameters can also be adjusted, and prompts or signals can be issued for deviations from normal working conditions. It is often used in various power generation, distribution and substations.

[0003] The Chinese patent with the announcement number CN216819012U discloses an electric control cabinet with a dehumidification function, including a cabinet, a dehumidifier is installed on the upper end surface of the cabinet, the dehumidification port of the dehumidifier is detachably connected to a dehumidification pipe, a dehumidification seat is fixedly connected to the top of the cabinet, a dehumidification hole is provided on the lower end surface of the dehumidification seat, the dehumidification pipe is connected to the dehumidification seat, humidity sensors are installed on both sides of the inner wall of the cabinet, and an axial flow heat dissipation fan is installed on the right side wall of the cabinet. By providing a dehumidifier, a dehumidification pipe, a dehumidification seat, a humidity sensor and a control panel, the electric control cabinet can be dehumidified by using them in coordination with each other, and the humidity sensor monitors the humidity in the cabinet in real time. When the electric control cabinet needs to be dehumidified, the control panel controls the dehumidifier to start dehumidification, and the moisture in the cabinet enters the dehumidifier from the dehumidification seat for heat exchange and discharge, and the dehumidification seat improves the dehumidification efficiency, so that the electric control cabinet can maintain good dryness and improve the safety of the electric control cabinet.

[0029] An operating mechanism 6 is provided between the middle sash mechanism 2 and the top rail mechanism 5; The operating mechanism 6 includes a hand ring 601 adapted to fit the outer groove 205, a spring 602 wrapped around the outer groove 205 is fixedly connected to the lower end surface of the hand ring 601, and a pull ring 603 is fixedly connected to the side of the hand ring 601; The operating mechanism 6 also includes a tray 604 sleeved on the second connecting column 501 . The tray 604 is fitted on the lower side of the gear 503 . A pull rod 605 is evenly and equidistantly fixedly connected between the tray 604 and the bracelet 601 . The pull rod 605 passes through the middle tube 201 and the wind tube 301 .

[0030] The working principle of the present invention is as follows: The starting motor 202 drives the fan 203 to rotate, so that the moving component draws air from the wind tube 301 and guides it to the humidity control component for blowing air. The air in the electric control cabinet can be circulated up and down at the front side of the device, which can make the air inside the electric control cabinet uniform, improve the uniformity of the internal environment of the electric control cabinet, and improve the accuracy of the first humidity sensor 404 and the second humidity sensor 508 in detecting the humidity inside the electric control cabinet.

[0031] Through the arrangement of the bottom rail mechanism 4 and the top rail mechanism 5, the fan 203 rotates and drives the second connecting column 501 connected thereto to rotate, and then through the engagement of the gear 503 and the gear column 507, the moving component circulates along the top plate 505 and the ring rail 403, thereby circulating the air in the electric control cabinet left and right, thereby improving the comprehensiveness of the moving component in stirring the air.

[0032] The air quality inside the electric control cabinet is made uniform by stirring the air inside the electric control cabinet, and when the air inside the electric control cabinet is in cooperation with the dehumidifier 105, the air inside the cabinet can be quickly and comprehensively processed uniformly, thereby improving the rapidity and timeliness of humidity control.

[0033] Through the setting of the operating mechanism 6, under normal working conditions, the wristband 601 is in the upper position of the outer groove 205 under the support of the spring 602, and the gear 503 is in the upper end position of the column groove 502 under the support of the tray 604, keeping the gear 503 always in meshing with the tooth column 507 to ensure the stability of the circulation of the moving component. When it is necessary to load, unload and overhaul the device, the personnel pull down the wristband 601 through the pull ring 603, so that the gear 503 loses the support of the tray 604 and automatically falls to the lower end of the column groove 502. At the same time, the gear 503 loses the meshing with the tooth column 507. At this time, the personnel can move the moving component toward the side plate 104 along the ring rail 403, so as to avoid the blocking of the device by the moving component and improve the adaptability of the main component.

[0034] The air inside the electric control cabinet is often humid. When the first humidity sensor 404 and the second humidity sensor 508 detect the problem of humid air, the dehumidifier 105 is first turned on to absorb dry gas from the drying hood 107 through the dehumidification pipe 106 and introduce it into the cabinet 101 for dehumidification. Due to the existence of the drying hood 107, the air filled in the drying hood 107 absorbs the heat generated by the device on the back wall of the cabinet 101 for a long time under normal working conditions of the electric control cabinet, so as to keep the dryness of the air inside the drying hood 107 by utilizing the heat generated by the device, so that the moisture content of the air introduced into the cabinet 101 by the dehumidifier 105 is low, the air humidity can be adjusted in time and effectively, and the efficiency of humidity control is improved.

[0035] When the air inside the electric control cabinet is humid, the refrigerator 204 is turned on for cooling while the dehumidifier 105 is working, and the cylinder 303 is extended to align the connecting rod 306 with the refrigerator 204. The moisture in the air condenses into water droplets on the surface of the refrigerator 204, and slides through the surface of the refrigerator 204 into the opened cylinder layer 302, and is finally absorbed by the sponge 307 through the water-permeable layer 305 at the bottom of the spacer 304, thereby improving the recyclability of the sponge 307, increasing its service life, and saving energy.

[0036] When the first humidity sensor 404 and the second humidity sensor 508 detect that the air inside the electric control cabinet is dry, the cylinder 303 is started to extend so that the sponge 307 is aligned with the refrigerator 204. At this time, when the fan 203 rotates to guide the air again, part of the air will be blown into the opened cylinder layer 302, and return after contacting the sponge 307, so that the air is humidified, thereby gradually increasing the humidity of the air during the cycle, which can maintain the humidity in the electric control cabinet and enable the electric control cabinet to work better.

[0037] The air flow in the cabinet 101 can be enhanced by guiding the air through the mobile components, and the air inside can be dried by absorbing heat through the drying hood 107, which can effectively dissipate heat in the cabinet and improve the heat dissipation performance of the electric control cabinet.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
