Description

High-voltage reactor with low noise

Technical Field

The utility model relates to a reactor specifically is a high-voltage reactor that noise is little.

Background

Reactors, also called inductors, are electrical conductors that, when energized, generate a magnetic field in a certain spatial area occupied by a conductor, so that all electrical conductors capable of carrying current are inductive in the general sense. However, the inductance of the electrified long straight conductor is small, and the generated magnetic field is not strong, so that the actual reactor is in a mode that a conducting wire is wound into a solenoid, and is called as an air-core reactor; in order to make this solenoid have a larger inductance, a core, called a core reactor, is sometimes inserted into the solenoid. Reactance is divided into inductive reactance and capacitive reactance, and the more scientific classification is that inductive reactance and capacitive reactance are commonly called reactor, however, since the inductor is existed in the past and is called reactor, so now the capacitor is called reactor, and the reactor is specially called inductor, and the reactor adopted in the power system is commonly the series reactor and parallel reactor. Series reactors are used primarily to limit short-circuit currents and also in filters in series or parallel with capacitors to limit higher harmonics in the network. The reactor in the power network is used for absorbing the charging capacity reactive power of the cable line. The operating voltage can be adjusted by adjusting the number of shunt reactors. The ultrahigh voltage shunt reactor has multiple functions of improving reactive power related operation conditions of a power system, and mainly comprises a capacitance effect on a light no-load or light load circuit so as to reduce power frequency transient overvoltage. Improve the voltage distribution on long transmission lines. The reactive power in the line is balanced as far as possible in the light load, so that the unreasonable flow of the reactive power is prevented, and the power loss on the line can be reduced. When a large unit is parallel to a system, the power frequency steady-state voltage on a high-voltage bus is reduced, the generators are conveniently parallel at the same time, and the self-excitation resonance phenomenon possibly occurring in a long circuit of the generators is prevented.

However, due to the unreasonable structural design, the noise of the reactor is high during operation, and the noise of the reactor is increased along with the time. Therefore, a high-voltage reactor with low noise is provided.
