[0002] A multi-functional power meter is an intelligent instrument with programmable measurement, display, digital communication, and power pulse transmission output. It performs functions such as power measurement, power metering, data display, data acquisition, and transmission. Multi-functional power meters are widely used in substation automation, distribution automation, intelligent buildings, and enterprise internal power measurement, management, and assessment. The measurement accuracy is 0.5 class, and it features on-site LED display and remote RS-485 digital interface communication using the MODBUS-RTU communication protocol.

[0003] However, existing power meters often lack protective housings, failing to protect the front panel of the power meter. This makes the front panel easily damaged when bumped or struck. Furthermore, existing protective housings are often installed and fixed with bolts, which is time-consuming and labor-intensive. Moreover, existing protective housings often lack dustproof and splashproof functions, causing inconvenience during use. Therefore, there is an urgent need for a new type of electrical automation instrument protection component to solve the above problems. Utility Model Content

In addition, existing protective shells are often installed and fixed by fixing bolts, which is time-consuming and laborious to install, and existing protective shells often do not have dustproof and splashproof functions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel electrical automation instrument protection component, comprising an electrical instrument body, a protective shell, a fixing plate, and a fixing structure. The front end of the electrical instrument body is snapped into the protective shell. An observation window is fixedly connected to the middle of the protective shell. Four square holes are opened at the bottom of the protective shell. Buffer foam and sealing rings are fixedly connected to the inner walls of the protective shell. The fixing plate is fixedly connected to the outer wall of the front end of the electrical instrument body. The fixing structure includes a limiting plate. Grooves are opened on both the left and right sides of the protective shell, and the limiting plate is fixedly connected to the inner wall of the grooves.

The upper and lower ends of the rotating shaft are rotatably connected to hinge seats two. Pressing plates are fixedly connected to the two hinge seats two. A buckle is fixedly connected to the outer wall of the rear end of the pressing plate, and the buckle snaps into the outer wall of the fixing plate.

[0006] Preferably, the observation window is made of transparent acrylic material, and the position and size of the observation window correspond to the position and size of the display screen on the front panel of the electrical instrument body.

[0007] Preferably, the position and size of the square hole correspond to the position and size of the buttons on the front panel of the electrical instrument body.

[0008] Preferably, both the cushioning foam and the sealing ring are U-shaped, and the sealing ring is located at the rear end of the cushioning foam.

[0009] Preferably, a silicone pad is fixedly connected to the inner wall of the bottom end of the protective shell. The surface of the silicone pad is provided with an antistatic coating. The length of the silicone pad is greater than the length of the four square holes. A rubber sealing ring is provided at the joint between the square holes and the silicone pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This novel electrical automation instrument protection component is equipped with a fixing plate and a fixing structure. The fixing plate is first fixed to the outer wall of the front panel of the electrical instrument body with adhesive. The protective shell is then snapped onto the front panel of the electrical instrument body. When the fixing plate presses against the buckle, the buckle drives the pressing plate to rotate outward, causing the torsion spring to contract under pressure. When the protective shell abuts against the fixing plate, the spring force of the torsion spring pushes the pressing plate, causing the buckle to engage in the slot. When the protective shell needs to be removed, the front end of the pressing plate is pressed, causing the pressing plate to lift, allowing the protective shell to be pulled forward. Through the combined use of the fixing plate and the fixing structure, the protective shell can be quickly installed and removed, making the operation convenient and efficient, improving installation efficiency, and facilitating use.

[0014] 2. This novel electrical automation instrument protection component features a protective housing. The display screen of the electrical instrument body can be observed through an observation window. A silicone pad is adhered to the inner wall of the protective housing. A rubber sealing ring is fixed to the seam between the square hole and the silicone pad using adhesive. The button of the electrical instrument body can be installed by pressing the silicone pad through the square hole. The protective housing and cushioning foam protect the front panel of the electrical instrument body from impacts. The sealing ring seals the seam between the protective housing and the outer wall of the front panel of the electrical instrument body, creating a sealed environment inside the protective housing, providing dust and splash protection. The protective housing protects the front panel of the electrical instrument body from dust and splashes while allowing the display screen to be observed and the buttons to be pressed, making operation convenient and quick.
