Description
Technical Field
[0001] This utility model belongs to the field of electrostatic detection technology, and in particular relates to an electrostatic detection device for power transmission and distribution. Background Technology
[0002] A power transmission and distribution system refers to a system in which the transmission and distribution of electrical energy is accomplished. In such systems, electrostatic discharge (ESD) detection equipment is typically used to detect static electricity in equipment such as electrical boxes. Currently available ESD detection equipment is usually a non-contact ESD voltmeter. Before use, this type of voltmeter requires connecting a grounding wire to the grounding terminal and the other end to an external grounding point. Therefore, when the user moves the voltmeter, the wire may detach. Furthermore, the probe of this type of non-contact voltmeter needs to be a certain distance from the object being measured, and the user needs to check the voltmeter reading to determine if the detection distance is within the effective range. This lengthy detection process results in low efficiency. Utility Model Content

While adjusting the distance between the probe 11 and the object being tested, the infrared ranging sensor 33 detects the distance and transmits the data to the microcontroller. The microcontroller displays the data on the display screen 32, allowing the user to intuitively see the distance value, thus enabling the user to find the effective distance for electrostatic detection more quickly and improving detection efficiency.
