Abstract

The utility model discloses an insulating resin casting type smoothing reactor, which comprises an iron core, a winding group is wound around the outer side of the iron core, and a gap slot is directly left between the turns of the winding group. The outer side of the winding group is wrapped with insulating resin, the outer side wall of the iron core is provided with a groove, the groove is filled with a cooling pipe, and the two ends of the cooling pipe are respectively provided with an inlet end and an outlet end, so the The inlet end and the outlet end extend out of the iron core. The insulating resin cast smoothing reactor can greatly prevent the coil from vibrating and greatly reduce the noise generation by filling the foamed rubber in the gap slot; The core and the winding group conduct direct heat exchange to reduce the temperature of the reactor without affecting the normal operation of the reactor.

Description

Insulating resin pouring type smoothing reactor

Technical Field

The utility model relates to a reactor technical field specifically is an insulating resin pouring type smoothing reactor.

Background

The well-known smoothing reactor consists of an upper iron core, a lower iron core, an iron core column, a copper coil sleeved outside the iron core column and a coil clamping frame; after the rectifier circuit part in the main circuit in the induction heating power supply equipment, the pulse number of the rectifier circuit is always limited, ripples always exist in output voltage, the ripples are harmful and need to be suppressed by a smoothing reactor, but the smoothing reactor with a simple structure is not only defective in appearance, but also has high noise, and often exceeds the limit of national standard environmental noise emission standard of industrial enterprise and plant boundary, and the insulation performance is not good, an insulation layer formed by an insulation sleeve on a coil is damaged due to heating, vibration and the like, and further causes harm of overlarge leakage current and the like, and the existing reactor has poor heat dissipation effect and cannot meet the use requirement.
