technical field

The invention relates to an energy-saving and environment-friendly dehumidification device for electrical equipment boxes, which is applied to the field of energy-saving and environment-friendly dehumidification and drying of equipment in various industries across the country.

Background technique

The existing equipment boxes such as mechanism boxes, terminal boxes, distribution boxes, communication signal boxes, inspection and maintenance distribution boxes, protection terminal boxes, fire alarm boxes, etc. Substation mechanism boxes, terminal boxes, distribution boxes, and on-site electrical equipment boxes frequently enter water, causing electrical equipment tripping and direct economic losses. Spring rain, substation mechanism boxes, terminal boxes, distribution boxes, on-site electrical equipment boxes, etc. have poor sealing quality and seepage of rainwater to the terminal block or excessive water accumulation at the bottom of electrical equipment or large rainwater humidity in the wiring. The surface of the row is damp and causes short circuit or ground loss. Frequent circuit breaker trips and electrical equipment alarms cause large-scale power outages. To deal with leakage of electrical equipment wiring drains requires a lot of manpower, material resources, and financial resources. Power outages bring great inconvenience to the lives of residents, and even cause significant direct or indirect economic losses to some electricity users, factories, and enterprises. Therefore, it is the object of the present invention to study the above problems.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed ways

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

Referring to Fig. 1, the present invention relates to an energy-saving and environment-friendly dehumidification device for an electrical equipment box, comprising a dehumidification tank 1 arranged in an electrical equipment box 11, the bottom of the dehumidification tank is provided with a number of ventilation holes 3, and the inside of the dehumidification tank There are silica gel particles 4 used to absorb moisture in the air as a hygroscopic agent. The top of the dehumidification tank is provided with an air intake pipe 5 communicating with the air in the inner cavity of the electrical equipment box. The air intake pipe is provided with a first solenoid valve. 6. The air inlet pipe of the dehumidification tank is also connected with a moisture discharge pipe 7, and the moisture discharge pipe is provided with a second electromagnetic valve 8, and the moisture content buried in the air is also provided inside the dehumidification tank. Hygroscopic silica gel particles inside the electrically heated helical tube 9.

A filter screen 10 of silica gel particles for blocking the moisture absorbent in the air is provided on the air hole at the bottom of the dehumidification tank.

The above-mentioned dehumidification tank is also provided with a temperature and humidity sensor 2 for sensing the temperature and humidity in the dehumidification tank.

During the implementation process, during normal work, open the first solenoid valve on the dehumidification tank and close the second solenoid valve to make the dehumidification tank communicate with the inside of the electrical equipment box, so that the humid air in the electrical equipment box can be released from the air in the dehumidification tank. The moisture absorbent is absorbed by the silica gel particles, and then the internal conditions are monitored in real time through the temperature and humidity sensor. When the air moisture absorbed by the silica gel particles exceeds the set value of humidity, the humidity can be adjusted at any time according to the needs. Dry silica gel (such as 80%), Then the first electromagnetic valve of the closed dehumidification tank is closed, the second electromagnetic valve is opened, and the electric heating coil is driven to start heating, so that the water absorbed in the silica gel particles is heated by the heater, the silica gel water is evaporated, the silica gel is dried, and the silica gel is heated and released. The moisture evaporates and is discharged to the outside air from the moisture discharge pipe, completing the self-recovery process of the silicone.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
