Description

Filter series reactor

Technical Field

The utility model belongs to the technical field of the reactor technique and specifically relates to a filter series reactor.

Background

The series reactor is mainly applied to inhibiting inrush current caused by switching-on impact and frequency harmonic waves, and can effectively reduce the influence on a power grid and an electric switch, so that the series reactor is widely applied to the field of electric power.

However, the reactor can produce vibrations in the use, and the too big loss that can increase self of vibration amplitude, the magnetic leakage is big to sound can be bigger and bigger, and the final three-phase is unbalanced, burns out the reactor, and the solution of solution mainly has a plurality of pull rods of installation and fastens, but the pull rod of current demand needs 6, and the installation degree of difficulty is high, thereby still causes unbalance easily and makes vibration amplitude weaken lessly.

In addition, the existing series reactor in the prior art has poor heat dissipation effect and is easy to cause accidents.
