Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric reactors, in particular to an electric reactor. BACKGROUND

[0002] Electric reactors are also called inductors, and are widely used in circuits. Because of the effect of electromagnetic induction in circuits, there is a certain inductance, which can play a role in resisting current changes. A conductor will produce a magnetic field in a certain space range when it is energized, so all current-carrying conductors have inductance in the general sense. However, the inductance of a long straight conductor is small, and the magnetic field generated is not strong, so the actual electric reactor is a wire wound into a solenoid form, called a hollow electric reactor. Sometimes, in order to make the solenoid have greater inductance, an iron core is inserted into the solenoid, called an iron core electric reactor. Electric reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is inductors (inductors) and capacitors (capacitors) collectively referred to as electric reactors. However, because in the past there were inductors first, and they were called electric reactors, so now people call capacitors capacitors, and electric reactors refer specifically to inductors.

[0003] During the long-term operation of the electric reactor, if the internal heat cannot be effectively dissipated, it will cause a series of negative effects. The continuous temperature rise will gradually increase the temperature of the winding and the core, exceeding the design allowable range, accelerating the aging process of the insulation material, reducing its dielectric strength and mechanical properties, and in severe cases, it may cause partial discharge or even insulation breakdown, threatening the safe operation of the equipment. High temperature will also promote the oxidation and decomposition of mineral insulating oil to generate acidic substances and sludge, which not only affects the cooling and insulation performance of the oil, but also may block the oil way, further worsening the heat dissipation condition, forming a vicious cycle.
