Abstract

The invention discloses a composite post insulator. The composite post insulator comprises a first solid post insulator, a hollow post insulator and a second solid post insulator. The hollow post insulator is arranged between the first solid post insulator and the second solid post insulator. The first solid post insulator is arranged at the upmost portion of the composite post insulator. The first solid post insulator, the hollow post insulator and the second solid post insulator are sequentially and fixedly connected. The invention further provides an electric reactor of the composite post insulator. The mechanical properties and reliability of the composite post insulator can be further improved, and the composite post insulator is high in using flexibility.

Description

technical field [0001] The invention relates to a composite post insulator and a reactor, in particular to a composite post insulator used for a dry reactor. Background technique [0002] In my country, with the increase of UHV lines, the consumption of post insulators for power transmission and transformation is also increasing. At present, the post insulators used in dry-type reactors for power transmission and transformation are mostly composed of multiple solid post insulators connected in series with metal flanges. Among them, as one of the solid post insulators, the proportion of composite material mandrel plus silicone rubber shed type solid post insulators is increasing. [0003] However, most of the insulators used in current reactors are composed of multiple solid post insulators connected in series with metal flanges. Therefore, this solid cylinder structure has the problems of heavy weight, long processing time, high manufacturing cost, inconvenient transportat...
