A mounting frame 5 is mounted on the top of the three-phase bridge module body 2. Two dust screens 11 are symmetrically mounted on the top of the mounting frame 5. The two dust screens 11 are connected to each other, and the bottoms of the two dust screens 11 are hinged to the two side edges of the top of the mounting frame 5. The two dust screens 11 are inclined. The mounting frame 5 is provided with several wire entry holes, the number of which is the same as the number of bolt terminals 3. The three-phase bridge module body 2 is mounted on the module base plate 1. The dust screens 11 block dust in the air and prevent dust from settling on the top of the three-phase bridge module body 2.

Under the premise of ensuring the dustproof effect, excellent heat dissipation effect is also ensured, avoiding the problem of poor heat dissipation caused by the accumulation of a large amount of dust on the screen.
