[0002] ‌Distribution network power loss‌ refers to the power loss in the distribution link during the transmission of power from power plants to users. These losses mainly include transformer loss, impedance loss of busbars and connection points, electromagnetic radiation loss, etc.‌

[0003] The power loss monitoring device for distribution network is a device used to monitor the power loss in the distribution network (a power network that receives power from the transmission network or regional power plant and distributes it locally or step by step according to voltage to various users through distribution facilities) in real time. It can accurately measure, record and analyze the power loss of the distribution network during the transmission and distribution of power, including various losses such as line loss and transformer loss.

[0004] For example, the power loss monitoring device for the distribution network with application number 202322597942.X fixes a clamping assembly on each of the two conductors at the upper end of the ammeter, and sets an upper clamping block and a lower clamping block that can be close to each other in the clamping assembly to fix the power lines; and sets a connecting assembly between the two clamping assemblies, and sets a connecting rod between the connecting assembly and the ammeter to fix the ammeter and the casing, so that the conductor is no longer stressed, avoiding damage to the conductor caused by long-term tension under long-term monitoring. However, the device still has certain defects; When the power loss monitoring device is used for a long time, a lot of dust will accumulate on the display screen of the flow meter, making it inconvenient to observe the contents on the display screen. When cleaning the dust on the display screen, it is necessary to find cleaning parts on the spot to clean it, so the humidity makes it inconvenient to clean the display screen. At the same time, the connecting rod on the ammeter is long, which makes it inconvenient to store it, so that the device occupies a large area when idle.
