Problems solved by technology
[0002] With the full coverage of electricity information collection systems, the problem of damage to collection systems and terminals by lightning strikes has become increasingly prominent. However, existing lightning protection products cannot provide absolutely safe and unlimited lightning protection, nor can they be used online. Actively report lightning strike information in the event of a lightning surge; and once a lightning surge occurs on the signal line, although the signal collection terminal or power collector is not damaged, the lightning interrupter may not be able to withstand the next lightning surge Surge, that is, the lightning breaker has lost its lightning protection function, and after a thunderstorm, the inspection personnel of the power department cannot check every collector point, even if the inspection is time-consuming. Therefore, it is self-evident to study the role of intelligent lightning protection devices

Embodiment Construction
[0023] Below in conjunction with accompanying drawing, the present invention will be further described:
[0024] Such as figure 1 As shown, a data signal line RS-485 intelligent lightning protection device is installed on the signal line for lightning protection monitoring of the signal line. It includes a lightning breaker 6 connected through a power information transmission signal line 9, a current Inductor 4, A / D converter 3, single-chip microcomputer 2, RS-458 chip 8, etc., the above-mentioned components are all connected with power supply 1, powered by power supply 1, grounding wire is set on the described lightning breaker 6, when the signal line When the M terminal detects a lightning surge, the lightning breaker 6 acts instantaneously to pass the current down the ground through the grounding wire. At the same time, the induction coil 5 set on the grounding wire senses the signal, and the current sensor 4 connected to the induction coil 5 senses the signal. Current, th...

The invention discloses a data signal line RS-485 intelligent anti-lighting device and method, and belongs to the technical field of intelligent signal lightning protection. The data signal line RS-485 intelligent anti-lighting device comprises a lightning blocker and a lightning monitoring unit. The lightning monitoring unit comprises a current inductor, an A / D converter and the like. An embedded chip is arranged on the lightning blocker, a grounding wire is provided with an induction coil, the induction coil is connected with the current inductor, the A / D converter, a single-chip microcomputer, an RS-485 chip and a photoelectric coupler in sequence, the photoelectric coupler is connected with a wireless collection terminal, and the wireless collection terminal transmits data to a data monitoring center of an electric power company. According to the data signal line RS-485 intelligent anti-lighting device and method, the intelligent anti-lighting device is added on a signal wire, electricity workers can effectively confirm whether each lightning blocker is stroked by lightning or not and anti-lightning times in the power data monitoring center according to data information fed back by a system in the electric power data monitoring center , the lightning blockers can be replaced before damage, work efficiency is high, safety is good, and popularization and application are facilitated.
Description
technical field [0001] The invention belongs to the technical field of intelligent signal lightning protection, and specifically relates to a data signal line RS-485 intelligent lightning protection device which can timely feed back the lightning strike signal back to the data monitoring center of the electric power company when a lightning surge occurs on the signal line and method. Background technique [0002] With the full coverage of electricity information collection systems, the problem of damage to collection systems and terminals by lightning strikes has become increasingly prominent. However, existing lightning protection products cannot provide absolutely safe and unlimited lightning protection, nor can they be used online. Actively report lightning strike information in the event of a lightning surge; and once a lightning surge occurs on the signal line, although the signal collection terminal or power collector is not damaged, the lightning interrupter m...
