AI Technical Summary

Technical Problem

The existing through-hole rectangular current transformer is cumbersome to install, cannot be quickly assembled, and is not easy to flexibly adjust the installation position, which reduces its applicability.

Method used

The design employs a clamping slide and connecting spring, which automatically engages with the base of the embedded block through spring force. Combined with the adjustment of the L-shaped slide plate and the mounting plate, it enables quick assembly and flexible adjustment of the installation position. The sealing cover and base are fixed by snap-fit, eliminating the need for screws.

Benefits of technology

It enables convenient assembly and flexible installation of the through-hole rectangular current transformer, improves the flexibility of use, and simplifies the disassembly and maintenance process.

Abstract

The utility model relates to the technical field of straight-through type current transformers, in particular to a straight-through type rectangular current transformer which comprises a straight-through type rectangular current transformer body, an embedded block is connected to the lower side of the straight-through type rectangular current transformer body in a clamped mode, and a base is fixedly connected to the lower side of the embedded block. The inner side face of the straight-through type rectangular current transformer body is slidably connected with two clamping sliding seats used for fixing the embedded block, and the two clamping sliding seats are automatically clamped to the two ends of the embedded block through the elastic force of the first connecting spring and used for clamping and fixing a base at the position of the embedded block. Therefore, the whole straight-through type rectangular current transformer can be quickly assembled, then the positions of the two L-shaped sliding plates can be flexibly adjusted to adapt to installation positions with different requirements, and meanwhile the straight-through type rectangular current transformer can be fixed through cooperation with grooves and screws in the positions of the installation rotating plates. And the use flexibility of the straight-through type rectangular current transformer can be improved.
