As an important part of power equipment, the small power distribution unit (SPDU)'s main function is to control, protect, distribute and monitor the power system. During use, due to the influence of environmental factors, such as dust, sand, fine particles, etc., it is easy to enter the inside of the small power distribution unit (SPDU), thereby affecting the normal operation and safety performance of the equipment.

Therefore, in order to ensure the stability and reliability of the small power distribution unit (SPDU) equipment, dust-proof measures need to be taken. Dust-proof measures can effectively prevent dust and other sundries from entering the small power distribution unit (SPDU), reduce the failure rate and maintenance times of equipment, and prolong the service life of equipment. At the same time, dust prevention measures can also reduce equipment maintenance costs, improve work efficiency, and reduce maintenance time and downtime losses.

Some common dust-proof measures include adding dust-proof devices such as filters and gaskets inside the small power distribution unit (SPDU). At the same time, external protection measures such as dust covers can be installed around the small power distribution unit (SPDU) to protect the equipment from dust, sand and other environments. factor damage.
