Research and analysis on the dustproof structure of low voltage switchgear

Abstract

This study improves the dustproof effect by changing the appearance structure of the low voltage switchgear. The exterior structure of the low-voltage switchgear adopts S profile to prevent dust from entering the cabinet body and make dust proof treatment at the connection of the cabinet board parts. Through the dust experiment, compare the protective effect of low-voltage switchgear with common appearance structure, low-voltage switchgear with common appearance structure after dust-proof processing and the new type of structure. Finally, it is concluded that the low-voltage switchgear can effectively reduce the entry of dust by increasing the complexity of dust entry channels, and the S-shaped appearance structure can reduce more than half of the dust entering compared with the ordinary appearance structure.
