Stable direct current does not produce electromagnetic radiation. Since it only produces an electric field and not an alternating magnetic field, even if it is ultra-high voltage direct current, its electric field is only strong enough to ionize the air and emit light. The optical radiation at this time is air ionization. What is emitted is not a wire and does not produce electromagnetic waves. The so-called electromagnetic radiation is the phenomenon in which energy is emitted from a radiation source into space in the form of electromagnetic waves. The flow of electric current in a conductor will generate an electric field, and the change of electric current in a conductor will generate a magnetic field, so the radiated waves are called electromagnetic waves.
In a DC transmission line, each level is adjusted and works independently without affecting each other. When one pole fails, you only need to shut down the faulty pole, and the other pole can still transmit no less than half the power. If a permanent fault occurs in any phase of an AC transmission line, the entire line must be powered off. The circuit through which DC power passes is called a DC circuit, which is a closed conductive loop composed of a DC power supply and a resistor. In this DC circuit, a constant electric field is formed. Outside the power supply, positive charges flow from high potential to low potential through the resistor. Within the power supply, the electrostatic force is overcome by the non-electrostatic force of the power supply, and then from low potential to high potential. This cycle forms a closed circuit. Current wire. Therefore, in a DC circuit, the role of the power supply is to provide a constant electromotive force that does not change with time to supplement the Joule heat consumed on the resistor. In a relatively simple DC circuit, the relationship between the power supply electromotive force resistance current and the voltage at any two points can be obtained based on Ohm's law and the definition of electromotive force. Complex DC networks can be solved based on Kirchhoff's equations. It includes two parts: the node current equation and the loop voltage equation. The former points out that the algebraic sum of the currents flowing into and out of the node at the intersection of one or more branches at any node is zero. This is a requirement of constant conditions. The latter points out that , the algebraic sum of the voltage drops in each part of any closed loop grid is zero, which is the result of the electrostatic field loop theorem, and the two form a complete system of equations.
