High Voltage Disconnect Switch

HGW4 series AC high voltage disconnector includes three single poles, each pole is of double column structure, which is mainly composed of base, post insulator and conductive part.

Overview

HGW4 series AC high voltage disconnector includes three single poles, each pole is of double column structure, which is mainly composed of base, post insulator and conductive part. Each pole has two insulating pillars, which are respectively installed on the bearing seats at both ends of the base and connected by cross connecting rods, which can rotate horizontally. The conductive knife switch is divided into two parts, which are respectively fixed on the post insulator, and the contact is in the middle of the two porcelain columns

Room.

When the operating mechanism acts, one post of the post insulator is driven to rotate by 90 degrees, and the other insulating post is also rotated by 90 degrees due to the transmission of the connecting rod, so the knife switch is opened and closed to the same side. In order to ensure the correct operation sequence between the disconnector and the grounding switch, a mechanical interlocking device is installed on the product or mechanism to ensure the sequential action of main opening and ground closing, ground opening and main closing.
