Description
Technical Field

Background art (the technology is suitable for 10kV distribution lines)
The high voltage is an electric service wire of which the alternating voltage of a distribution line is more than 1000V or the direct voltage is more than 1500V. The low voltage is low voltage when the alternating current low voltage is below 1000V or the direct current voltage is below 1500V. The safe voltage does not exceed 36V of alternating current and 50V of direct current. The 1000kV and above alternating voltage class in the power system supplies extra-high voltage, and is generally only used as a large-power long-distance transmission line because the energy loss in the transmission process can be reduced. The voltage used in different fields is different, because according to the formula of P ═ IU, in order to reduce the loss of electric energy in the transmission process, the current must be reduced, and to ensure the total power is not changed, the voltage must be properly increased, and then the voltage is passed through the step-down transformer substation, and finally reaches the home of the user. High voltage electricity is particularly hazardous compared to ordinary power supplies. There are two special cases of high voltage shock: firstly, high-voltage electric arc electric shock and secondly, step voltage electric shock. Generally, the influence of high voltage electricity on the human body is electric shock and electromagnetic waves. The overhead power line protection area is a safety area which must be set for ensuring the safe operation of the built overhead power line and the normal electricity utilization of people's life. In densely populated areas such as factories, mines, towns, villages and the like, when an area in two parallel lines formed by the sum of the horizontal distance of a lead sideline after the windage yaw is calculated to the maximum and the horizontal safety distance of the lead sideline after the windage yaw from a building operates around high-voltage electricity, proper protective measures should be taken and the safety distance should be kept, otherwise, the high-voltage electricity should be cut off first and then constructed so as to avoid electric shock and death.
