[0002] With the development of society and the increase in electricity demand, electricity metering and billing technology is also constantly developing and innovating. The CT low-voltage branch monitoring terminal is a widely used electricity metering equipment. It has the advantages of high accuracy, good stability, and easy installation. It is a convenient and practical device that can monitor and alarm low-voltage branches.

[0003] In the prior art, a Chinese patent with announcement number CN212008797U discloses a low-voltage shunt monitoring device, which adopts the scheme of "including a monitoring body and an arc-shaped outer block, wherein the arc-shaped outer block is installed and fixed on both sides of the upper end of the monitoring body, a lower side protrusion is arranged above the right end of the monitoring body, a fixed concave block is arranged on the outer side of the lower side protrusion and on the monitoring body, and a lower side semicircular groove is arranged in the middle of the upper end of the monitoring body". The U-shaped buckle block composed of a U-shaped shell, a rotating ring, a connecting short column and a buckling groove is conveniently fixed in the fixed concave block. When closing the monitoring cover, the monitoring cover can be well fixed by the U-shaped buckle block, and the rotating ring of the U-shaped buckle block is sleeved and connected to the inside of the monitoring cover to effectively prevent it from falling off, and the connecting short column is effectively limited and fixed, so that the U-shaped shell can be well fixed on the fixed concave block through the buckling groove, so that the monitoring cover is effectively closed, so that it is not easy to fall off during use, which is convenient for use.

[0004] However, the above scheme still has some shortcomings. For example, the above scheme uses a U-shaped buckle block to clamp the monitoring cover and the monitoring body, and then fixes them with bolts. This connection and fixing method is too complicated and has too many installation steps, which increases the workload of the staff. In addition, the above scheme lacks a mechanism for separating and fixing two or more lines, which makes the lines easily entangled and knotted, causing inconvenience to the subsequent arrangement and maintenance of the lines. In view of this, the utility model proposes a low-voltage branch monitoring device using a double CT opening. Utility Model Content
