Title:

LINE FAULT DETECTION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2023/098830

Kind Code:

A1

Abstract:

A line fault detection apparatus, comprising a housing (1000), a fault detection device (2000), a heat dissipation device (3000) and an air flow exhaust device (4000), wherein the housing (1000) has an inner cavity, a support plate (1100) is provided in the inner cavity, and divides the inner cavity into a detection cavity (1200) and a heat dissipation cavity (1300), which are in communication with each other, and an air inlet (1400) is provided on the heat dissipation cavity (1300); the fault detection device (2000) is mounted on the support plate (1100), is located in the detection cavity (1200), and is configured to detect a fault of a medium and low voltage distribution grid line; the heat dissipation device (3000) comprises an air intake drive assembly (3100), which is arranged in the heat dissipation cavity (1300), and can introduce external air into the heat dissipation cavity (1300) through the air inlet (1400) and blow the external air into the detection cavity (1200); and the air flow exhaust device (4000) is fixed to the housing (1000), and the air flow exhaust device (4000) can draw air out of the detection cavity (1200). The line fault detection apparatus can solve the problem that water circulating cooling and heat dissipation has an unsatisfactory heat dissipation effect during actual use, is inconvenient for a worker to maintain, and cannot effectively ensure continued normal operation of a broken conductor detector in high altitude environments.
