AI Technical Summary

Technical Problem

Existing outdoor current transformers suffer from problems such as low cleaning efficiency and difficulty in disassembly due to dust accumulation and housing installation, which affect their accuracy and stability.

Method used

A high-precision outdoor current transformer was designed, which adopts a linkage structure between the removable housing and the base plate. Combined with the air extraction pipe, the chip collection box and the air extraction unit, it realizes automatic dust cleaning. The continuity and stability of the air extraction process are ensured by the one-way valve and the return spring. At the same time, the housing is clamped by the airbag to ensure stable installation.

Benefits of technology

It enables automatic dust cleaning of the transformer body, improves accuracy and stability, simplifies the disassembly and installation process of the housing, and meets the needs of long-term outdoor use.

Abstract

本发明属于电流互感器技术领域,尤其为一种高精度户外电流互感器,包括底板,所述底板的顶部安装有互感器主体,所述底板的顶部安装有可移除的壳体,所述壳体用于对互感器主体表面的防护;本发明通过壳体的防护以及抽气管、存屑盒、抽气部和限位部的联动配合,实现了对互感器主体灰尘的自动清理。当壳体向下移动盖住互感器主体时,由于限位部随着壳体一起向下移动,因为限位部对抽气部处进行推动,促使抽气部抽取存屑盒处空气,使抽气管处产生负压,从而将互感器主体处的灰尘抽取到存屑盒内。这种自动清理灰尘的方式,避免了灰尘在互感器主体表面堆积,有效提高了互感器在户外使用的精度和稳定性,确保其能长期准确可靠地工作。
