Power failure detection device

Abstract

The invention discloses an electric power fault detection device. The device comprises a base and an outer shell, wherein the bottom of the outer shell is supported on the base so as to seal the outershell; an inner fence board located in the outer shell is installed on the base, a convection heat dissipation channel used for communicating the interior of the inner fence board with the exterior of the outer shell is formed between the inner wall of the outer shell and the outer wall of the inner fence board, and a plurality of semiconductor chilling plates located over the convection heat dissipation channel are installed on the inner wall of the outer shell. When the convection heat dissipation channel is opened; the semiconductor chilling plate enables airflow flowing downwards to be generated in the convection heat dissipation channel. Hot air rising to the top of the outer shell is sucked into the convection heat dissipation channel and is discharged; and after detection is finished, the outer shell descends to the base to close the convection heat dissipation channel, so that external air can be prevented from entering the outer shell when heat dissipation and detection are finished, the outer shell can be kept clean and dry, and the service life of the electric power detection instrument is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of power fault detection, in particular to a power fault detection device. Background technique [0002] Existing power equipment needs regular maintenance. During power maintenance, it is usually necessary to use a power detector to detect whether the power equipment is normal. Because the power line is long and there are many power equipment, the power detector often needs to perform detection work for a long time, and Since the electronic detection element will generate more heat, the long-term work of the power detector will cause the electronic detection element to work in a high temperature environment, which will not only affect the service life of the electronic detection element, but also affect the stability and detection accuracy of the electronic detection element. Negative effects, especially in summer when the temperature is higher. [0003] At present, the heat dissipation methods of electron...
