Problems solved by technology

Copper-aluminum equipment clamps include a fixed platen and multiple movable platens set at intervals. The movable platen is connected to the fixed platen by screws, and the power cord is tightened between the fixed platen and the movable platen. However, there is a gap between adjacent movable platens, causing the power cord to The contact area with the equipment clamp is relatively small, and the electrical conductivity is poor; and it takes about 4 minutes for a skilled worker to install a equipment clamp. The quality is not guaranteed. Poor installation may reduce the current carrying capacity of the line. Under heavy load, it will cause the temperature of the connection point of the power line to rise, and even burn the power line.

Abstract

The invention discloses an equipment line cleat of a distribution line, and belongs to the field of an electric network. The equipment line cleat solves the technical problems that in the prior art, the contact area of the equipment cable cleat and a power supply line is small, and the consumed time for mounting the equipment line cleat is long. The equipment line cleat provided by the invention comprises a connector, wherein a connecting hole is formed in the side wall of one end of the connector, and accommodating grooves are formed in the end surface of the other end of the connector; a fixing screw is connected to the connecting hole, and the fixing screw is connected with equipment of the distribution line; a power supply line of the distribution line is mounted in the accommodating grooves. The equipment line cleat disclosed by the invention is applied to the electric connection of the equipment and the power supply line in the electric network.

Description

【Technical field】 [0001] The invention relates to an equipment clamp of a power distribution circuit. 【Background technique】 [0002] In the construction of existing power distribution lines, copper-aluminum equipment clamps are used as transition connections for the connection between the equipment on the line and the power line. Copper-aluminum equipment clamps include a fixed platen and multiple movable platens set at intervals. The movable platen is connected to the fixed platen by screws, and the power cord is tightened between the fixed platen and the movable platen. However, there is a gap between adjacent movable platens, causing the power cord to The contact area with the equipment clamp is relatively small, and the electrical conductivity is poor; and it takes about 4 minutes for a skilled worker to install a equipment clamp. The quality is also not guaranteed, and poor installation may reduce the current carrying capacity of the line. In the case of heavy load, i...
