Pincer-shaped mutual inductor with waterproof function

Abstract

The pincerlike mutual inductor with the waterproof function comprises a pincerlike shell, a fixed core mechanism, a movable core mechanism and a wiring group, a forward shell comprises a first shell body, a second shell body, a first cover plate, a second cover plate, a buckle and an epoxy glue filling layer, and an arc-shaped movable core strip in the movable core mechanism can move along the circle center and is matched with an elastic piece; during actual installation, when the buckle fastens the first outer shell and the second outer shell, the cutting surfaces on the two sides of the elastic piece can be in good contact with the cutting surfaces on the two sides of the arc-shaped core fixing strip, the measurement precision is improved, in addition, after the pincerlike mutual inductor is assembled, epoxy glue filling layers are poured into the first outer shell and the second outer shell firstly, and then the elastic piece can be fixed to the arc-shaped core fixing strip. Therefore, the waterproof effect can be improved.

Description

technical field [0001] The invention specifically relates to a clamp-shaped transformer with waterproof function. Background technique [0002] At present, the primary equipment and secondary equipment in the power system are still relatively separated from each other. The primary equipment in the primary and secondary integrated power system will contain some secondary equipment intelligent units, so that the primary equipment is more intelligent, and the primary equipment is more intelligent. The equipment has its own functions such as measurement, metering, relay protection, monitoring, and control. In this regard, it is required that the clamp-type transformer can meet the relevant requirements in terms of accuracy, installation scheme and waterproof. In order to ensure that the cutting surface of the iron core is not rusted and rusted, the clamping force on both sides of the clamp-type transformer is increased, resulting in difficult installation. The iron core is easi...

AI Technical Summary

Problems solved by technology

In this regard, the clamp transformer is required to meet the relevant requirements in terms of accuracy, installation scheme and waterproof. In order to ensure that the cutting surface of the iron core is not damp and rusted, the clamp transformer increases the fastening force on both sides, resulting in difficulty in installation. The iron core is easily shifted to both sides due to external force, resulting in the inability to fit the cutting surface, and the measurement accuracy is accurate

And if the fastening force on both sides is not increased, the cutting surface of the finished product will be easily damp and rusted during the operation of hanging the net.

Rust on the cutting surface of the iron core causes gaps in the bonding of the cutting surfaces, and deviations in the sensing accuracy of the transformer, which seriously cause misjudgment of the power grid and lead to tripping
