When the rainy season comes, the influence of moist air on electrical appliances can not be ignored. It will not only cause various faults, but also greatly shorten the service life of electrical appliances. Oil smoke purifier installed outside should be specially protected. Install an awning over the oil fume purifier. The canopy can shade the sun and prevent rain from entering the oil fume purifier. Lampblack purifier The power box can cause electrical failure; in addition, when installing the fume purifier, it is necessary to use the iron rack or other platforms to pad the equipment so as to prevent the rain from splashing into the power box from the ground.
Kelan environmental protection Two 018 The utility model improves the working environment of the power supply, improves the moisture proof and sun protection performance, and is dust-proof and waterproof. IP55 level is achieved under IEC 60529:2013 standard. This protection level can reduce the impact of rainwater on electrical appliances, ensure the stability and service life of the fume purifier, and make users more comfortable.
The design of the heat sink at the top of the electric box not only improves the heat dissipation and waterproof performance of the equipment, but also greatly improves the aesthetic appearance of the equipment.
Attachment: description of IP protection level (data from Baidu)
The IP (INGRESS PROTECTION) protection rating system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION), which classifying electrical appliances according to their dust-proof and moisture resistance characteristics. The IP protection level is made up of two numbers. The first numbers indicate the level of electrical dust prevention and prevention of foreign objects invasion. The outer parts, including tools, human fingers, etc., can not be touched into the live part of the appliance, so as not to be electrocuted). The second numbers indicate the degree of sealing of the electric appliance against moisture and water immersion. The larger the number, the higher the protection level.
First digit dust-proof level after IP
No special protection for people or objects outside.
Prevention of solid foreign invasion greater than 50mm diameter
Prevent the human body (such as palm) from touching the interior parts of the appliance due to accidents, and prevent the invasion of larger objects (larger than 50mm diameter).
Prevention of solid foreign invasion greater than 12.5mm diameter
Prevent human fingers from touching parts inside electrical appliances to prevent foreign objects from entering in medium size (larger than 12.5mm).
Prevention of solid foreign invasion greater than 2.5mm diameter
Tools to prevent diameters or thicknesses larger than 2.5mm, wires and similar small objects to enter and touch parts inside electrical appliances.
Prevention of solid foreign invasion greater than 1.0mm diameter
Tools to prevent diameters or thicknesses larger than 1.0mm, wires and similar small objects to enter and touch parts inside electrical appliances.
Prevention of foreign objects and dust
While preventing foreign matter from intruding, it can not completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of electrical appliances.
Prevention of foreign objects and dust
Completely prevent foreign matter and dust intrusion.
Second digit after IP: waterproof grade
No special protection for water or moisture.
Prevent immersion of water droplets
Vertical drops of water, such as condensate, do not damage electrical appliances.
When you tilt 15 degrees, you can still prevent water droplets from flooding.
When the electrical appliance inclines to 15 degrees vertically, the dripping will not damage the electrical apparatus.
Prevent sprinkler water immersion
To prevent rain or prevent damage caused by electrical water sprayed in the direction with a vertical angle less than 60 degrees.
Prevention of splashing water immersion
Prevent splashing water in every direction from damaging electrical appliances and causing damage.
Prevent water from spraying
Prevent low-pressure water spraying for at least 3 minutes.
Prevent big waves from entering
A large amount of water that lasts for at least 3 minutes.
Prevention of water immersion during immersion
Immersion in water for 30 minutes in a depth of 1 meters
Prevent immersion of water when sinking.
In the depth of more than 1 meters of water to prevent continuous immersion effect. The exact conditions are specified by the manufacturer for each device.
