Abstract

The embodiment of the invention discloses a high-voltage line proximity early warning method. The high-voltage line proximity early warning method comprises the following steps that: a plurality of displacement distances and actually-measured electric field intensity corresponding to the displacement distances on a displacement line are obtained; high-voltage line voltage level is determined according to the obtained distances and electric field intensity; safety electric field intensity at a safe distance corresponding to the high-voltage line voltage level is determined according to the high-voltage line voltage level; the magnitudes of the obtained actually-measured electric field intensity and the safety electric field intensity are judged; if the actually-measured electric field intensity is stronger than or equal to the safety electric field intensity, it is determined that a construction worker is in a danger range. With the high-voltage line proximity early warning method provided by the invention adopted, whether the construction worker is in the danger range can be effectively determined, and the safety of the construction worker can be ensured.

Description

technical field [0001] The invention relates to the technical field of electric power safety, in particular to a method and device for early warning of near-electricity of high-voltage lines. Background technique [0002] With the development of society, the development of all walks of life is increasingly dependent on stable power supply. Safe and reliable power supply is of great significance to ensuring social stability and promoting economic development. The primary task in the process of various power project construction and equipment maintenance. The construction and maintenance of transmission lines and equipment is an important link in the supply of stable power. Damage to transmission lines or equipment often means that the power supply in a certain area is interrupted. Therefore, the safe operation of transmission lines and equipment is inseparable from the maintenance of electric workers. Electric workers often need to maintain and repair some electric facilitie...
