Abstract

The invention provides a metering box arranged on a cable branch line. The metering box comprises a box body, a metering device and a load switch, wherein the box body is provided with a line incoming hole and a line outgoing hole; the metering device is arranged in the box body; the load switch is arranged in the box body; a first line outgoing column of the load switch is electrically connected with a second line incoming column of the metering device. The metering box provided by the invention has the advantages that the load switch is arranged in the box body, the first line outgoing column of the load switch is electrically connected with the second line incoming column of the metering device, the protection to the load switch is realized by the box body, and then the purpose of arranging the load switch on the cable branch line is realized, so that the power supply reliability of the cable branch line can be effectively improved; meanwhile the load switch and the metering device are arranged in the same box body, so that the internal space of the metering box is effectively utilized, and the installation of the load switch is convenient.

Description

technical field [0001] The invention relates to the technical field of cable branch line load switch installation, and more specifically relates to a metering box. Background technique [0002] High voltage lines on the ground are supported by columns. In order to ensure the reliability of power supply, it is necessary to set up a load switch. Usually, the load switch is a pole-mounted load switch, the load switch is arranged on a column, and the load switch is supported by the column. [0003] For the cable high-voltage line, the cable high-voltage line includes multiple cable branches. In order to measure the electricity and realize branch control, each cable branch is equipped with a metering box, and the metering box has a metering device. Since the cables need to be buried underground, the existing pole-mounted load switches cannot be installed on the cable branch lines, resulting in poor reliability of the power supply of the cable branch lines. [0004] To sum up, ...
