Abstract

The invention relates to a new type of multi-point grounding resistance measuring device, which consists of a grounding rod to be tested, an auxiliary grounding rod, a current measuring instrument, a voltage measuring instrument, a signal processing device, a control management device, an analysis and processing device, and the like. The current measuring instrument and the voltage measuring instrument are respectively connected between the rod and the auxiliary grounding rod, the current measuring instrument and the voltage measuring instrument are connected to the signal processing device through the transmission system, and the signal processing device and the control management device are connected through the transmission system , the control management device and the analysis and processing device are connected through a transmission system. The invention measures the grounding resistance and the soil resistivity at the same time, and can automatically measure multiple working points at the same time, and only needs one auxiliary grounding rod, which saves ground pile materials and avoids damage to the working environment to the greatest extent. Destruction; Compared with manual multiple measurements, it saves costs, improves measurement accuracy, and can update measurement data at any time.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to a device for measuring grounding resistance. Background technique [0002] Lightning is a special atmospheric phenomenon caused by the discharge of charged clouds in the air. Lightning is an important cause of damage to electronic equipment, which threatens the safe and stable operation of electronic information systems in various fields such as construction, railways, civil aviation, communications, industrial control, and military. Lightning protection is one of the measures to solve the above problems. In the current field of lightning protection, the setting of grounding devices has become one of the most critical links. It not only involves lightning discharge, but is more related to personal safety, equipment safety and system security. For normal operation, the current various technical specifications have express provisions on the specific settings of the groundin...
