Problems solved by technology

[0003] At present, there is no industry standard for the human body to be subjected to induced electric shocks under high-voltage transmission lines. For example, in the "Environmental Impact Assessment Technical Guidelines for Power Transmission and Transformation Projects", corresponding predictions have been made on the impact of power-frequency electric fields and power-frequency magnetic fields under high-voltage transmission lines. and evaluation, but does not involve the test and measurement of the human body being subjected to induced electric shock under the high-voltage transmission line

specific Embodiment

[0021] At the lowest point of sag under a 500kV double-circuit EHV transmission line, the measured electric field strength is 5.8kV / m, which is enough to cause some induced electrical phenomena. Among them, the current threshold of the human body's physiological response to the power frequency steady-state current is shown in Table 1, the charge threshold of the human body's physiological response to the transient electric shock is shown in Table 2, and the energy threshold of the human body's physiological response to the transient electric shock as shown in Table 3.

Abstract

The invention discloses a wearable real-time monitoring device for human body induced electricity under a high-voltage transmission line. The wearable real-time monitoring device comprises a metal conductor, an insulating stick, ankle bands and insulating boots capable of being worn on feet. The ankle bands are connected with a ground lead. The other end of the ground lead is connected with a ground rod. A current probe is arranged on the ground lead and connected with a monitor. The monitor is further connected with a voltage probe. A static electricity leakage resistor is arranged on the ground lead in a serial connection mode. The wearable real-time monitoring device serves as the erecting reference of a high-voltage circuit and the safety reference of the work under the transmission line, and is simple in structure and convenient to operate and use.

Description

technical field [0001] The invention relates to a wearable real-time monitoring device for human body induction electricity under a high-voltage transmission line. Background technique [0002] There is a strong power frequency electric field under the high-voltage transmission line, and the main impact on the ecology is the current. When people or animals touch the conductors insulated from the ground in the electric field, a tingling current may be generated, that is, electric shock. , as the amount of current increases, this stimulation may range from a feeling of stinging or burning due to the electric shock, to being unable to shake off and breathing difficulties, and if the current is very strong, ventricular fibrillation will occur. Electric shocks can be divided into transient electric shocks and steady state electric shocks according to the time of action. Among them, transient electric shock refers to the electric shock caused by the electric charge accumulated on...
