US 12,555,723 B2 · Electric power disconnect switch with integrated bypass switch

Abstract

A disconnect switch including a main disconnect switch integrated with a bypass switch. The purpose of he bypass switch is to provide a parallel path for temporarily closing the disconnect switch so that the main disconnect switch can be tested (i.e., opened and closed) without interrupting the power flow through disconnect switch. The bypass switch is integrated with the main disconnect switch and supported by the same insulator structure, which avoids duplication of parts and provided for a compact unit suitable for deployment on a pole or other mounting structure outside a substation. The bypass switch also includes a frame-mounted linkage at ground voltage operated by an actuator at ground voltage, which avoids the use of “hot sticks” to operate the bypass stitch.

Dependent claims

An electric power disconnect switch with integrated bypass switch for an electric power line operating at a line voltage, comprising:

a frame at a ground voltage;
an insulator structure comprising a ground voltage end connected to the frame and a line voltage end spaced apart from the ground voltage end;
a main disconnect switch supported by the line voltage end of the insulator structure;
a bypass switch supported by the line voltage end of the insulator structure connected in parallel with the main disconnect switch;
a bypass switch drive linkage supported by the frame at the ground voltage;
an insulated link connected between the bypass switch at the line voltage and the bypass switch drive linkage at the ground voltage;
an actuator at the ground voltage for operating the bypass switch drive linkage to open and close the bypass switch independently of the main disconnect switch.

4 more elements
