Method and apparatus for electric field alarming

Abstract

The invention discloses a method for electric field alarming. The method comprises: the current field intensity is detected and a field intensity detection value corresponding to a field intensity signal is obtained; whether the current field intensity detection value is larger than a first preset field intensity value is determined; if so, a first alarm signal is outputted; when the first alarm signal is received, alarm prompting is carried out; whether the current field intensity detection value is larger than a second preset field intensity value is determined; if so, a second alarm signal is outputted; and when the second alarm signal is received, alarm prompting is carried out. The first preset field intensity value is smaller than the second preset field intensity value. Therefore, segmented prompting is realized by outputting alarm signals twice. Compared with the existing method of sending out one piece of alarm prompting information by setting one preset field intensity value, the provide method enables the humanization effect to be improved and the functions to be diversified. In addition, the invention also discloses an apparatus for electric field alarming.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a method and device for electric field alarm. Background technique [0002] When troubleshooting the power equipment of the distribution network, it must be carried out in accordance with the prescribed procedures. For example, when the 10KV overhead line is overhauled, the basic process is "disconnect the switch at both ends of the line for power failure-electric test rod inspection-hook the ground wire-start the maintenance work. Among them , The electric inspection step of the electric probe is to ensure that the 10KV line is powered off to ensure the safety of the staff. However, due to the influence of the high-voltage line, there is a large electric field around it. When the staff enters the high-voltage dangerous area, they cannot perceive the potential of the electric field. The danger of causing the staff's body to be affected, such as headache, fatigue, insomnia; or even caus...

Problems solved by technology

However, due to the influence of the high-voltage line, there is a large electric field around it. When the staff enters the high-voltage dangerous area, they cannot perceive the potential danger of the electric field, which will affect the staff's body, such as headache, fatigue, insomnia; even cause more serious injury

[0003] There is only one preset field strength value in the current alarm method, because the strength of the field strength is increasing when the staff is approaching the generator body, when there is only one preset field strength value, the value is set too much If the value is too high, the staff may suffer greater injuries. If the value is set too low, the alarm will start when the value is far away from the generator, causing unnecessary tension

It can be seen that this method does not have a transitional buffer stage, which is not humane enough
