High-voltage cable fault tester: safe distance for high-voltage electricity When other charged bodies are introduced near the electric body, the introduced charged body will be subjected to force, that is, there is an electric field in the space around the charged body. The electric field strength is a high-voltage cable fault tester: safe distance for high-voltage electricity When other charged bodies are introduced near the electric body, the introduced charged body will be subjected to force, that is, the space around the charged body There is an electric field in it. Electric field strength is a physical quantity that expresses the magnitude and direction of the force that the electric field acts on a charged body. It is represented by the letter E. There are positive and negative charges in nature. There is an electric field around the electric charge. These are static relative to observation. , an electric field whose charge does not vary with time.
So if you don't pay attention to the safe distance of high-voltage electricity, what kind of harm will it cause? High-voltage cable fault tester to introduce to you! (1) Causes explosions and fires. Although the static electricity is not large, the tantalum voltage is high, which is prone to discharge and electric sparks. In the workplace with flammable liquids, static sparks may cause fires; In areas with explosive mixtures, static sparks may cause an explosion. High-voltage cable fault tester: safe distance for high-voltage electricity (2) Electrostatic shock, although the energy of static electricity is very small, the electric shock caused by this will not directly kill people, but it can cause people to fall and fall, causing In the second accident, electric shock can also make people nervous and hinder work. (3) Static electricity hinders normal production.
Static electricity will interfere with some electronic control equipment and affect the normal control operation. Especially on the ground of high-voltage equipment, 220KV voltage level E=35KV/M330KV voltage level E=5~8KV/M500KV voltage level E=7~10KV/M1000 voltage level E=9~15KV/M The standard of electric field influence Most of the requirements are controlled below 10KV, and for substation switch places, individual locations should not exceed the 15KV/MO standard. Therefore, when doing high-voltage withstand voltage leakage current, especially when using a frequency-modulated series resonance withstand voltage test device, the high-voltage cable fault tester recommends that you keep a safe distance of more than 5 meters.
