In recent years, with the development of economy and the continuous improvement of the living standard of people, the demand of people on electric power is higher and higher. The power grid system becomes more and more dense, and the high-voltage line of the power grid also brings some potential safety hazards while bringing convenience to life and production. Dense high-voltage lines are distributed in complex and complicated environments such as mountains, rivers, lakes, cities and the like, so that on one hand, inspection needs to cost a large amount of manpower and material resources, and on the other hand, the dense high-voltage lines are inevitably damaged by artificial or irresistible factors. The faults of the power line not only threaten personal and property safety, but also bring inconvenience to life.
While the rapid development of economy in China, the basic construction of township construction, rail transit, bridges and the like is also steadily carried out. Large construction facilities and construction vehicles can be seen anywhere in a construction site, and the condition of damaging a power line sometimes happens. According to incomplete statistics, safety accidents caused by the fact that construction vehicles cut and collide power transmission lines and related equipment account for more than 50% of total accidents, and the accidents mostly occur at night. From national statistical data, external force damage accidents are mostly caused by cranes, tower cranes and concrete pump trucks, and account for over 60 percent of overhead line accidents. At night or during construction in severe weather, the sight of constructors is blocked, and accidents of short circuit and open circuit of the high-voltage line caused by the fact that the specific position of the high-voltage line cannot be confirmed often occur, and account for more than 70% of external force accidents.

Is suitable for various severe scenes. Meanwhile, two power supply modes can be adopted, so that the product is more reliable, the power failure and the severe environment can be better tested, and the operation and maintenance cost of the equipment is reduced.
Current induction power-taking begins to supply power to equipment when a power transmission line reaches a starting current. When the circuit has no current due to disconnection, the built-in high-capacity lithium battery can maintain the normal work of the equipment until the power returns to normal. Meanwhile, a control chip inside the equipment specially carries out intelligent management on the opening and closing of each module, and the power consumption of the equipment is reduced. Two ways are used for supplying power, thereby ensuring that the front-end equipment 1 can work normally under any condition.

As shown in fig. 3, the power-taking CT is disposed on a single high-voltage power transmission line, i.e., the number of turns of the primary coil is N 11, make the number of turns of the secondary coil N2N, i.e. the number of turns of the coil of the power CT is N, and the current of the primary coil are I1、I2Then, there are:
however, when the current-taking CT coil works with small current, the core magnetizing current IμCannot be ignored, so there are:
then get the output power P of the electricity CT coil0May be expressed as:
wherein S is the sectional area of the iron core, mu is the magnetic conductivity, and L is the length of the magnetic circuit of the iron core.
In practical engineering applications of product design, U2The size of the excitation current, which is usually designed to be 5V or 3.3V, is determined by the voltage value; at the moment, if the iron core material and the related structure are selected, the iron core sectional area S, the magnetic conductivity mu and the iron core magnetic path length L are determined; after ensuring to reach the designed voltage value U2Under the condition of (3), the optimal value of the number of turns of the current-taking CT coil can be obtained by utilizing an extreme value principle and a correlation formula, and the practical number of turns of the coil can be obtained by performing engineering design and debugging according to the optimal value.
