AI Technical Summary
Existing grounding clamp testing equipment relies on battery power. When the battery is depleted, it cannot detect the connection status between the grounding clamp and the grounding conductor, posing a safety hazard.
It employs a self-generating module and an RF transmitting module. The relative movement between the grounding clamp and the grounding conductor generates an induced current, which drives the RF transmitting module to send signals to indicate the connection status, thus avoiding dependence on an external power source.
It enables reliable detection of the connection status between the grounding clamp and the grounding conductor without external power supply, enhancing construction safety and avoiding the risk of detection failure due to power depletion.
