Problems solved by technology

In the past power tunnels, there is usually no special layout of AC 220V or other power supply circuits dedicated to auxiliary equipment in the tunnel, which brings great challenges to the development and deployment of cable monitoring systems and tunnel lighting systems in this case. Inconvenient, so usually the battery can only be used as the main energy supply. On the one hand, the power consumption of the equipment is required to be extremely low. At the same time, the battery must be replaced regularly, which brings great inconvenience to the work.
[0003] Since the power tunnel is characterized by long d

Description

technical field [0001] The invention relates to a power tunnel cable non-contact induction power-taking device capable of obtaining electric energy through a non-contact induction power-taking method under the condition that there is no power supply line in the power tunnel. Background technique [0002] At present, the construction of auxiliary equipment (lighting, mechanical ventilation, and fire prevention warning) for power tunnels is gradually launched. In the past power tunnels, there is usually no special layout of AC 220V or other power supply circuits dedicated to auxiliary equipment in the tunnel, which brings great challenges to the development and deployment of cable monitoring systems and tunnel lighting systems in this case. Inconvenient, so usually the battery can only be used as the main energy supply. On the one hand, the power consumption of the equipment is required to be extremely low. At the same time, the battery must be replaced regularly, which brings...
