Document Type and Number:
WIPO Patent Application WO/2024/055365
Kind Code:
A1
Abstract:
The present invention relates to the technical field of circuit devices, and specifically comprises a three-phase inconsistent protector with extremely high reliability. The protector comprises: a box body having a lateral surface comprising an opening, and a box cover disposed on a side of the box body; the edge of the side of the box body comprising the opening being provided with a plurality of uniformly and equidistantly arranged securing insertion columns; the edge of the box cover being provided with securing insertion holes which are identical in number, at corresponding positions, of suitable dimensions, and matched for insertion connection with the securing insertion columns; an inner lateral wall of the box body having mounted thereon a desiccant box filled with a desiccant, the outer wall of the desiccant box having a mesh-like structure; and an outer wall of the box cover having embedded therein a transparent observation window. In the present invention, the protector is divided into a box body and a box cover, and the box body and box cover act in concert in insertion connection via securing insertion columns and securing insertion holes, thereby achieving convenient installation or disassembly, and allowing for periodic internal maintenance; and the desiccant box arranged in the box body can absorb internal air water vapor, preventing corrosion to internal components, and prolonging service life.
