Combined device used for reliably connecting double-loop cable terminals with equipment clamp

Abstract

The invention relates to a combined device used for reliably connecting double-loop cable terminals with an equipment clamp. The combined device used for reliably connecting the double-loop cable terminals with the equipment clamp comprises a hoop group and a post insulator, wherein the post insulator is fixedly installed on the hoop group; the hoop group comprises a hoop plate and a U-shaped hoop; the hoop plate is a polygonal plate, and the two ends of the hoop plate are bent outwards to form connection lugs; installation holes are symmetrically formed in the connection lugs; the U-shaped hoop is fixed to the hoop plate, and the two ends of the U-shaped hoop are fixedly installed in the installation holes of the connection lugs through a fastening nut separately; a connection seat is arranged on the top surface of the hoop plate; and one end of the post insulator is fixedly installed on the connection seat, and the other end of the post insulator is fixedly installed on an insulatorbottom plate through a bolt. The combined device used for reliably connecting the double-loop cable terminals with the equipment clamp is fixed to a pole-tower, the two double-loop cable terminals canbe directly connected with the equipment clamp, and meanwhile, a fixing effect is achieved; and the minimum safety distance is increased by the post insulator, and reliable and stable connection between the double-loop cable terminals and the equipment clamp is achieved, so that the safety running of a circuit is ensured.

Description

technical field [0001] The invention relates to a combined device for reliably connecting a double-circuit cable terminal and a device clamp, and belongs to the technical field of power transmission. Background technique [0002] The instantaneous current of the generator set in the power plant is large when it is started. In order to meet the needs of the self-provided power plant for grid-connected power generation, the line used is not only used as the starting power supply, but also for future grid-connected power generation. Therefore, the line can only be selected with a relatively large diameter type wire, and the single-circuit power cable, whether it is an aluminum core or a copper core, cannot match it in terms of ampacity. Therefore, this kind of line generally uses a double-circuit aluminum core power cable. [0003] The double-circuit aluminum core power cable needs double-circuit cable terminals. The double-circuit cables are climbed from both sides of the iron...

Problems solved by technology

[0003] The double-circuit aluminum core power cable needs double-circuit cable terminals. The double-circuit cables are climbed from both sides of the iron tower to the bottom of the cross-arm respectively, because the distance between the two cable terminals and the distance between the wire clamps and the conductor equipment are too large to be connected The three are directly connected together, and there is no transition device specially used for this connection in the prior art

However, not only must the connection be reliable at this place, but it also needs to be fixed in the horizontal direction of the pole tower to ensure the minimum safe distance between the live part and the pole tower, so as to prevent sideways swing caused by external forces such as wind, which will affect safe operation.
