Problems solved by technology

In the repair or power maintenance site, in order to ensure the safety of operation and maintenance personnel, it is necessary to use live indication equipment to indicate the liveness of the circuit; however, the existing live indication equipment has limited indication effect and is easily damaged by high voltage breakdown, which leads to the loss of indication function , and there are no relevant protective measures, which has buried hidden dangers for the life safety of operation and maintenance personnel.
[0004] In view of the poor indication effect and safety of the above-mentioned charged indicating device, no effective solution has been proposed

Abstract

The invention provides an electric indicating protection device and method and a high-pressure protection garment with the device. The device comprises a central processing module, a sensing module, an alarming module and a protection module. When the device is close to an electric high-voltage line or an electric high-voltage device, the propagation direction of polarized light emitted by a polarized light generating component deviates, the light transmission amount received by a polarized light receiving component is smaller than the conduction threshold value of a light-sensitive resistor or a light-sensitive diode, and the light-sensitive resistor or the light-sensitive diode is switched off. When the central processing module detects that the light-sensitive resistor or the light-sensitive diode is switched off, the central processing module triggers an alarming module to give an alarm. According to the protection module, when the device is in contact with the electric high-voltage line or the electric high-voltage device, an insulation unit is used for insulation, and a current dredging unit is used for conducting contact currents to the ground. The indicating accuracy of the electric indicating protection device is improved, and safety of personnel is improved.

Description

technical field [0001] The invention relates to the technical field of electrification indication, in particular to an electrification indication protection device, a method and a high-voltage protective clothing with the device. Background technique [0002] With the rapid development of the economy, electricity has become an inseparable source of energy for thousands of households, resulting in a substantial increase in total electricity consumption. During peak power consumption, power transmission and distribution lines will run at full load or even short-term overload; and power lines and transmission towers cover a wide area, and the natural environment is harsh, resulting in many transmission line failures. [0003] In order to ensure the continuity of power supply, power line operation and maintenance personnel need to repair power lines and equipment. In the repair or power maintenance site, in order to ensure the safety of operation and maintenance personnel, it i...
