[0002] Electrical cabinets contain numerous components, enabling the control, connection, and power supply of equipment through a single cabinet. They are also one of the main components of modern power equipment. Because electrical cabinets contain many electronic components, they need to be kept relatively dry inside. Excessive moisture will affect the operation of the electronic components.

[0003] Current electrical cabinets lack moisture monitoring mechanisms, relying instead on regular switching and maintenance by staff to release moisture. This is detrimental to the long-term operation of the equipment, and since moisture accumulates gradually, untimely release can easily lead to circuit safety issues. Therefore, a humidity monitoring and alarm device for the internal environment of electrical cabinets is proposed. Utility Model Content

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figure 1-3 This utility model discloses an internal humidity monitoring and alarm device for an electrical cabinet, comprising a cabinet body 1, an installation box 2 detachably connected to one side outer wall of the cabinet body 1, an inner groove 5, a plug-in plate 6 fixedly connected to one side wall of the inner groove 5, a humidity sensor inserted into the plug-in plate 6, a through hole 7 through the side wall of the inner groove 5 located in the middle of the plug-in plate 6, and the inner groove 5 communicating with the inside of the cabinet body 1 through the through hole 7, and the sensing end of the humidity sensor extending into the cabinet body 1 through the through hole 7;

[0016] A sealing plate 9 is rotatably connected to one side edge of the opening of the inner tank 5. A dehumidification port 10 is detachably embedded in the middle of the sealing plate 9. A small exhaust fan is connected inside the dehumidification port 10. A connecting groove 8 is opened in the middle of the bottom side wall of the inner tank 5. A controller and two relays are connected inside the connecting groove 8. A warning light 11 is detachably connected in the middle of the top side wall of the mounting box 2. The warning light 11 is electrically connected to the relay inside the inner tank 5.

[0017] The technical benefits of this solution are as follows: The humidity sensor is inserted into the connector board 6, ensuring its sensor head extends into the cabinet 1 through the connecting hole 7. After powering on and starting operation, when the humidity inside the cabinet 1 is too high, the controller and relay will activate the warning light 11. The illuminated warning light 11 alerts staff, prompting them to intervene promptly and prevent safety issues. This eliminates the need for periodic activation, reducing staff workload. Furthermore, the warning function allows staff to respond quickly, significantly reducing problems caused by excessive humidity in the cabinet 1.

[0018] A fan cabinet 3 is detachably connected to the top side wall of cabinet 1. A blower is connected inside the fan cabinet 3, and the air outlet of the fan cabinet 3 is connected to the inside of cabinet 1. An exhaust port 4 is opened through the side wall of cabinet 1 away from the installation box 2 and near the bottom. A filter screen is embedded in the exhaust port 4. An outer frame 12 is detachably connected to the bottom of the fan cabinet 3. Electric heating tubes 13 are evenly and detachably connected inside the outer frame 12. The blower of the fan cabinet 3 is connected to the relay in the inner groove 5. The bottom of the cabinet 1 is set with an inclined structure.

[0019] The technical effect of this solution is as follows: A fan cabinet 3 connected to the top of the cabinet 1 can blow air into the cabinet 1. The relay can automatically turn on when the humidity is too high, thereby blowing the humid air in the cabinet 1 downward and finally expelling it from the exhaust port 4, thus realizing the cleaning function and ensuring the dryness of the cabinet 1. When the humidity reaches the standard, the operation of the fan cabinet 3 can be turned off by the relay.

[0020] Specifically, in use, a rubber pad is fixed to the inner wall of the plug-in plate 6 to increase the stability of the humidity sensor after plugging in. At the same time, the elasticity of the rubber pad ensures that the transmission end of the humidity sensor is stably plugged into the connecting hole 7. The humidity sensor and the corresponding control and relay are powered on. When the humidity is too high, the controller will activate the relay to turn on the warning light 11. The illumination of the warning light 11 reminds the staff to intervene in time. At the same time, the relay can also turn on the blower in the fan cabinet 3. The blower blows air into the cabinet 1. The air blown into the cabinet 1 expels the humid air inside the cabinet 1 from the exhaust port 4 to ensure that the cabinet 1 is dry. To improve the drying effect, an outer frame 12 and an electric heating tube 13 are added to ensure that the air blown into the cabinet 1 has a temperature. This can better change the original humid environment. By setting the bottom of the cabinet 1 into an inclined structure, the blown air can be guided to make the humid air expelled more smoothly.

[0021] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0022] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
