Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric reactors, and particularly relates to an explosion-proof electric reactor. BACKGROUND

[0002] An electric reactor is a kind of power equipment used to generate inductive reactance in a circuit to control current or voltage. Its main function is to limit the fluctuation of current by increasing inductance, thereby playing a role in protecting power systems and electrical equipment. The basic working principle of the electric reactor is based on Faraday's law of electromagnetic induction, which generates inductive resistance (i.e. inductive reactance) in the circuit through an inductor coil. This inductive reactance can suppress overcurrent or adjust reactive power. In power systems, the main uses of electric reactors include current limiting, voltage regulation, reactive power compensation, and filtering. Current limiting reactors can limit the size of fault current to prevent equipment damage or larger-scale power system failures, and are usually installed between the incoming line or bus of a substation; voltage regulating reactors are used to stabilize the voltage of the power grid to prevent voltage fluctuations; reactive power compensation reactors are used to compensate for reactive power to maintain voltage stability; and filter reactors are used to filter out harmonics of a specific frequency to prevent the influence of harmonics on the system.

[0003] However, traditional electric reactors mostly use core and winding structures, which are prone to heat accumulation under high load or sudden current changes, especially in sudden situations such as short-circuit faults, which may cause insulation material degradation, leakage, and even explosion risks. At the same time, traditional electric reactors mostly rely on passive heat dissipation, relying on natural air cooling or environmental cooling, and cannot actively dissipate heat, which may cause internal temperature to rise during high-load operation, thereby affecting the service life and operating efficiency. To solve the above problems, we propose an explosion-proof electric reactor. SUMMARY
