Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of inductance coils, and particularly relates to an inductance coil for avoiding electrostatic short circuit. Background Art
[0002] A coil is formed by winding a wire around an insulating shaft one turn by one turn. The wires are insulated from each other, and the insulating tube can be hollow or can contain an iron core or a magnetic powder core;
[0003] An inductance coil is a device that works based on the principle of electromagnetic induction. When an electric current flows through a wire, a certain electromagnetic field will be generated around this wire, and the wire itself in this electromagnetic field will have an inductive effect on the wires within the range of this electromagnetic field. The effect on the wire itself that generates the electromagnetic field is called "self-inductance", that is, the changing current generated by the wire itself generates a changing magnetic field, and this magnetic field further affects the current in the wire; the effect on other wires within the range of this electromagnetic field is called "mutual inductance".
[0004] However, static electricity will be generated during the use of the inductance coil, and the inductance coil is directly exposed to the air. When the distance between adjacent wires is relatively close, static electricity is generated between the two wires, which is likely to cause the insulating layer of the wire to be broken down by the static electricity, resulting in a short circuit of the inductance coil.
