Embodiment Construction
[0025] The technical solutions of the present invention will be described in detail below in combination with specific implementation methods and accompanying drawings.
[0026] The present invention includes a ground wire pile body 11, a ground wire head 14, a non-contact ground wire detection module, a photoelectric sensor 52, a wireless communication LoRa module, and a motion unit; wherein, the motion unit includes a tumbler lock, an electromagnet module 34, and a mechanical unlocking device; The pin lock includes a pin lock ball 31 and a pin lock spring 32 .
[0027] The non-contact ground wire detection module is used to identify the installation state of the ground wire head 14, and trigger the external control system from the standby state to the working state according to the installation state of the ground wire head 14. The non-contact ground wire detection module uses radio frequency identification technology for data communication, including RFID tags and readers; ...

The invention discloses an anti-misoperation locking device for wireless intelligent ground wire management. The anti-misoperation locking device comprises a ground wire pile body, a ground wire head, a photoelectric sensor and a motion unit, wherein the motion unit comprises a spring lock, an electromagnet module and a mechanical unlocking device; and the pin tumbler lock comprises a pin tumbler lock bead and a pin tumbler lock spring. According to the invention, the modular mechanical design, the wireless radio frequency identification technology and the LoRa wireless communication technology are adopted at the same time, so that the reliability of the suspended ground wire is ensured, and meanwhile, the real-time detection and acquisition of the state of the ground wire on an operation site can be realized; and the cable laying construction amount is reduced, and long-distance wireless communication is carried out without being influenced by other equipment.
Description
technical field [0001] The invention belongs to the blocking technology for preventing electrical misoperation in a power system, and in particular relates to a wireless intelligent ground wire management anti-misoperation blocking device. Background technique [0002] In the power system, most of the accidents are caused by the wrong operation of electrical equipment. In substations and power plants, hanging ground wires is a necessary safety measure in on-site maintenance. By hanging the ground wires on the incoming side of the equipment, a reliable grounding point is formed to protect people and equipment. Among the currently used anti-misoperation locking devices, the communication mode of the ground wire management machine mostly adopts two modes of cable communication and wireless communication. In the cable communication mode, a large number of cables need to be buried to provide power and communication for the device, and the construction volume is very large; in th...
