Lightning protection high-voltage live-line digital display and blocking apparatus

Abstract

The invention provides a lightning protection high-voltage live-line digital display and blocking apparatus. The apparatus comprises a sensor, an input protection unit, a lightning arrester, a filter, a signal processing unit, an output driving unit, an LED display screen and a blocking contact, wherein the sensor is connected with the input protection unit, the input protection unit is successively connected with the filter, the signal processing unit and the output driving unit through a lead wire, the output driving unit is respectively connected with the LED display screen and the blocking contact through the lead wire, and a self-check unit and the lightning arrester are respectively connected between the input protection unit and the filter through the lead wire. In case of stormy weather or normal weather, the apparatus can be used for indicating live-line conditions and size of voltages of high-voltage equipment and can also block correlation electrical equipment in a forced mode, so that the operation safety of switch electrical equipment is improved, output voltage data is synchronized to a monitoring room, and real-time monitoring is realized.

Description

technical field [0001] The invention relates to the technical field of safety protection devices, in particular to a high-voltage electrified digital display and locking device for lightning protection. Background technique [0002] With the rapid development of our country, electrical equipment has become an important tool that cannot be obtained in people's lives. Nowadays, people's dependence on electrical equipment has led to an increasing demand for electrical energy, which has a great impact on the safety and stability of power system equipment. Sex requirements are also getting higher and higher. In order to ensure the safe and stable operation of the power system, it is necessary to perform correct electrical operations on various electrical appliances and power devices, and to prevent accidents caused by the five vicious misoperations. [0003] The "five preventions" mentioned in the power system specifically refer to: preventing mis-distribution and mis-closing of...
