The switch cabinet is equipped with custom-developed electronic code locks (including switch operation holes, grounding knife switch holes and rear cabinet door operation holes). The electronic code locks adopt dual numbering, and the preset position information -KKS is encoded into the electronic code locks to identify the necessary conditions for unlocking. Integrate the gis map of 6kV switches with equipment information, preset the corresponding position information and KKS coding information, and construct a digital graphic system for factory-use switches. The system is equipped with typical electrical operation tickets, featuring built-in five-proof logic interlocks. Operators are authorized according to the operation ticket process to complete the invoicing process, and the operation information is sent to the mobile APP terminal for execution. The operator holds a mobile terminal and the position information of the switch cabinet to mutually identify each other, completing the necessary conditions for the operation of the switch cabinet. Meanwhile, the intelligent encoded lock, under the condition of meeting the five-prevention logic setting, completes the unlocking and has a voice prompt function, effectively preventing the risk of misoperation such as incorrect intervals and live grounding knife (grounding wire) closing.
