Description

Technical Field

[0001] The utility model relates to a reactor, in particular to a reactor for preventing the iron core from falling off. Background Technique

[0002] A reactor, also called an inductor, is widely used in circuits. Due to the effect of electromagnetic induction in the circuit, there is a certain inductance, which can play a role in preventing current changes. When a conductor is energized, a magnetic field will be generated in a certain space range it occupies. Therefore, all current-carrying conductors have inductance in a general sense. However, the inductance of a long straight energized conductor is small, and the generated magnetic field is not strong. Therefore, the actual reactor is a wire wound in the form of a solenoid, called an air-core reactor; sometimes, in order to make this solenoid have a larger inductance, an iron core is inserted into the solenoid, called an iron-core reactor. Reactance is divided into inductive reactance and capacitive reactance. A more scientific classification is that inductors (inductors) and capacitors (capacitors) are collectively called reactors. However, because there were inductors first in the past and they were called reactors, the capacitors people talk about now are capacitors, and reactors specifically refer to inductors. In the power system, a reactor is an important electrical equipment, mainly used for limiting short-circuit current, absorbing high-order harmonics of the power grid, filtering, shunt compensation, series compensation, etc.

[0003] However, in the traditional reactor design, the iron core cannot be in direct contact with the ground. Direct contact with the ground will cause adverse effects due to multi-point grounding of the iron core. During the overall baking process of the reactor, the iron core is prone to sink and come into contact with the ground. Therefore, designing a safe and simple fixing device for the reactor base is of great significance for improving the use efficiency of the reactor and ensuring safety during use. Content of the Utility Model

[0004] The utility model provides a reactor for preventing the iron core from falling off to solve the technical problem that the iron core is prone to sink and come into contact with the ground during the overall baking process of the reactor.

The cross-section of the plug pin is L-shaped and is made of a 4mm steel plate.

[0007] Further, the cross-section of the lower clamping member is L-shaped.
