Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of power detection equipment, and in particular to the technical field of wireless inductive AC signal acquisition devices. Background Technology
[0002] During operation, electrical equipment or power lines typically require the acquisition of AC signals to determine their operational status. However, during operation, the following situations often occur: the AC current is small when the power consumption is low, and becomes large when the power consumption is high. When a line fault occurs, the AC current becomes even larger due to the fault. Therefore, it is necessary to acquire and analyze the AC current signal to determine the fault location and carry out timely repairs. Most existing AC signal acquisition devices are complex in structure, large in size, require multiple external lines for detection, and have large reading errors, which causes inconvenience to users and affects repair efficiency. Summary of the Invention

This device can wirelessly acquire AC signals from AC circuits at different locations, effectively preventing damage caused by collisions between AC signal transformers and AC circuits, and effectively preventing external interference from affecting the accuracy of AC signal acquisition and analysis. It has a simple and practical structure, small size, and is conducive to improving maintenance efficiency.
[0004] To achieve the above objectives, this utility model proposes a wireless inductive AC signal acquisition device, comprising a handheld terminal, a shielded outer shell, an electric telescopic rod, an AC signal transformer, a distance sensor, a voltage conversion module, an AD conversion module, a microcontroller, a touch screen, and a built-in power supply. The handheld terminal is covered by a shielded outer shell, and an electric telescopic rod is mounted on top of the shielded outer shell. An AC signal transformer is mounted on top of the electric telescopic rod, and several distance sensors are mounted on the side opening of the AC signal transformer. A voltage conversion module is housed inside the shielded outer shell. The input terminal of the voltage conversion module is connected to the AC signal transformer, and the output terminal of the voltage conversion module is connected to the input terminal of the AD conversion module. The output terminal of the AD conversion module is connected to the microcontroller, and the microcontroller is connected to the touch screen. The distance sensors are connected to both the electric telescopic rod and the microcontroller. The built-in power supply is located inside the shielded outer shell and is connected to each of the electric telescopic rod, AC signal transformer, distance sensor, voltage conversion module, AD conversion module, microcontroller, and touch screen via circuitry.
[0005] Preferably, the side of the AC signal transformer is provided with several miniature night vision cameras, which are respectively connected to the built-in power supply and the touch screen.
[0006] Preferably, the electric telescopic pole is an insulated hollow plastic telescopic pole, and the connection lines of the AC signal transformer and the distance sensor are hidden in the hollow part of the electric telescopic pole.
