Description

Technical Field

[0001] The invention belongs to the technical field of power quality analysis, in particular to a power quality analyzer. Background Art

[0002] A power quality analyzer refers to a special product that detects and analyzes the quality of power grid operation. It can generally provide harmonic analysis and power quality analysis in power operation, and can also conduct long-term data collection and monitoring of power grid operation.

[0003] The use of the power quality analyzer requires the use of a flexible current probe. The flexible current probe is used to wrap around the line, and the connecting wire at the other end of the flexible current probe is connected to the power quality analyzer for detection. The flexible current probe is generally in a circular shape and connected to a connecting wire. One end of the circular ring of the flexible current probe can be opened to facilitate encircling the line for detection.

[0004] When the existing power quality analyzer is in use, in a narrow sense, people will think that the power quality analyzer only refers to the power quality analyzer body, but the device is generally equipped with several flexible current probes and a packaging bag after purchase. Therefore, in a broad sense, people will think that the power quality analyzer not only has the power quality analyzer body but also includes flexible current probes and packaging bags. Because its main panel and buttons are exposed to the outside, generally when it is not needed, the user will generally put it in the packaging bag and store it in a backpack, but this situation will cause the panel of the device to be squeezed, and the buttons of the device will be pressed for a long time and cannot rebound. After this situation continues for a period of time, it will cause the device to malfunction, and it is easy for the buttons to fail to rebound and the display panel to be damaged, and some positions cannot display. In this case, a protection device needs to be designed to protect it. Summary of the invention
