Abnormal monitoring mechanism for high-voltage current detection equipment

Abstract

The invention provides a high-voltage current detection equipment abnormity monitoring mechanism which comprises a shell, power transmission lines are fixedly connected to the two sides of the shell, a melt is arranged in the shell, monitoring mechanisms are arranged in the shell and located on the two sides of the melt, and power saving mechanisms are arranged in the monitoring mechanisms. According to the abnormity monitoring mechanism for the high-voltage current detection equipment, when a fuse is used, current enters the interior of the shell through the power transmission line and passes through the melt, the temperature of the melt is increased along with the current, when the current is close to fusing current, the temperature of the melt is high, and the melt is softened, and at the moment, the monitoring mechanism monitors the deformation degree of the melt; and when the use of the voltage transformer is influenced by the deformation of the melt, a worker is reminded to replace the fuse, so that the purposes of monitoring the deformation degree of the melt and preventing the use of the voltage transformer from being influenced by the deformation of the melt when the fuse works are achieved.

Description

technical field [0001] The invention relates to the technical field of voltage transformers, in particular to an abnormal monitoring mechanism for high-voltage current detection equipment. Background technique [0002] Similar to a transformer, a voltage transformer is an instrument used to transform the voltage on the line, mainly to measure the voltage, current, power and electric energy of the line, or to protect valuable equipment, motors and transformers in the line when the line fails. In order to prevent the voltage transformer from being damaged by high voltage, a high voltage fuse needs to be installed inside. [0003] When the high-voltage fuse is used, its internal melt will fuse when the current reaches a certain level, which will cause the circuit to break. However, when the current is close to the fuse size, the melt will soften. When the vibration force of the device is applied, the melt will gradually deform, resulting in a decrease in the diameter of the me...
