Description

[Technical Field]

[0001] The present invention relates to a tamper-proof and theft-proof switchboard lock. [Background technology]

[0002] Ground-mounted solar power plants are being installed for the purposes of environmental conservation activities and effective land utilization. In many ground-mounted solar power plants, the solar power generation system that generates electricity is located away from the distribution board, so the solar power generation system and the distribution board are connected by copper wires buried underground. The distribution board is stored in a cabinet attached to a utility pole. In recent years, there have been cases of wire theft, where underground wires have been pulled out and stolen. Measures to prevent wire theft, such as reinforcing the locks on the cabinet, are necessary.

[0003] Locks with high security are known, such as the one disclosed in Patent Document 1, which has a stopper and a striker inside the main body to create a locked state for the door. [Prior art documents] [Patent documents]
