Dustproof coil protection shell

The invention discloses a dustproof coil protection shell in the field of coil protection shells, which comprises a protection shell, the protection shell comprises an outer shell and an inner shell, a coil is placed in a placement cavity between the outer shell and the inner shell, the placement cavity penetrates through the upper end of the protection shell to form a heat dissipation hole, and the upper end of the protection shell is provided with a dustproof device covering the heat dissipation hole; the coil is placed in the placement cavity to be protected, the formed heat dissipation holes are beneficial to heat dissipation of the coil, the heat dissipation effect of the annular continuous heat dissipation holes is better, the dustproof device can prevent dust from entering the protective shell from the heat dissipation holes, and the dust is prevented from interfering with normal work of the transformer. 本发明公开了线圈防护壳领域的一种能够防尘的线圈防护壳，包括防护壳，防护壳包括外壳和内壳，线圈放置于外壳和内壳之间的放置腔内，放置腔贯穿防护壳的上端形成散热孔，防护壳上端安装有覆盖散热孔的防尘装置；将
