[0002] The power distribution system is an important project in urban construction. It transmits electric power from the substation to the interior of users' homes, enabling the stable operation of the city. In the power distribution system, a wattmeter is often set to measure electric power. Electric power includes active power, reactive power, and apparent power, and it is one of the important tools to ensure the safe operation of the power system. In addition, the wattmeter is also applicable to product tests in fields such as electric propulsion, motors, fans, water pumps, and wind power generation.

[0003] The prior art discloses a wattmeter for a power distribution system that is convenient for installation with the publication number: CN217332558U, which includes a wattmeter main body and an installation base box arranged outside the wattmeter main body. A placement groove is provided inside the installation base box. Installation pieces are symmetrically installed on both sides of the installation base box respectively, and the installation pieces are welded to the installation base box; a lifting head is provided on the front end face of the installation base box. There are two lifting heads, and the two lifting heads are symmetrically arranged above and below the wattmeter main body respectively. A lifting groove is provided on the front end face of the installation base box, and the lifting head extends into the lifting groove. A top pressing plate is arranged on both sides of the placement groove inside the installation base box. Thus, when installing the wattmeter main body, through the elastic top pressing action of the top pressing plate, the two sides of the wattmeter main body can be restricted to prevent the wattmeter main body from shaking, improving the stability of the wattmeter installation. This wattmeter for a power distribution system that is convenient for installation realizes the ability of the wattmeter to be quickly installed and disassembled, increases the flexibility and practicality of the wattmeter installation, and solves the problem that it is very troublesome to use bolts for installation and during disassembly and maintenance.
