AI Technical Summary

Technical Problem

In the existing switchgear equipment, the heat dissipation design lacks physical isolation and forced convection cooling functions, resulting in low heat dissipation efficiency and easy high-temperature aging of components.

Method used

A highly sensitive protection device for arc temperature rise early warning of switchgear is designed. By setting up a heat dissipation protective box and fan assembly inside the switchgear, a unidirectional convection path is formed, which physically isolates the heat and forces convection to dissipate heat, thereby reducing the thermal impact of the early warning device itself.

Benefits of technology

It effectively removes a large amount of heat in a short time, ensuring that the equipment operates stably at a suitable temperature and preventing component aging.

Abstract

This utility model discloses a high-sensitivity protection device for arc temperature rise early warning of switchgear, comprising: a switchgear body, an early warning device body fixedly connected to the inner surface of the switchgear body, a monitoring probe fixedly connected to the front surface of the early warning device body, the early warning device body and the monitoring probe being electrically connected, a heat dissipation protective box fixedly connected to the inner surface of the switchgear body, the early warning device body located inside the heat dissipation protective box, an air duct connected to the rear surface of the heat dissipation protective box, a fan assembly installed on the inner wall of the air duct, and an air outlet on the top of the switchgear body. Through the above components and the physical isolation of the heat dissipation protective box, the direct thermal impact on the early warning device body is reduced. By drawing air through the fan assembly, forced airflow is formed, causing the air to flow rapidly within the heat dissipation protective box and fully contact the early warning device body, which can remove a large amount of heat in a short time and ensure stable operation of the equipment at a suitable temperature.
