The invention discloses a novel gap lightning protection device and belongs to the field of electric power safety. The novel gap lightning protection device comprises a connector (2), a wiring electric conductor (4), a wiring electrode (6) and a grounding electrode (8). A gap m is reserved between the wiring electrode (6) and the grounding electrode (8) and is smaller than the length n of the wiring electric conductor (4). The grounding electrode (8) is driven by an automatic device to do linear motion. After a protection cable is stricken by the lightning stroke, lightning stroke over-voltage is led to the wiring electrode (6) through the protection cable, the connector (2) and the wiring electric conductor (4), the lightning stroke over-voltage breaks down the gap between the wiring electrode (6) and the grounding electrode (8) to cause an electric arc, and is led to the grounding electrode (8), and then led to the ground through a grounding electric conductor (5), the lightning stroke electric arc is transferred from the protection cable, and therefore a protective circuit is prevented from being damaged by the lightning stroke. According to the novel gap lightning protection device, the gap between the wiring electrode and the grounding electrode can be suitable for protection cables of various voltages and various models.
Description
technical field [0001] The invention relates to the field of electric power safety, in particular to a lightning protection device used for adjustable gaps in distribution lines of electric power systems. Background technique [0002] Surge protector, also called surge protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a peak current or voltage suddenly occurs in the electrical circuit or communication line due to external interference, the surge protector can conduct the shunt in a very short time, thereby avoiding damage to other equipment in the circuit caused by the surge [0003] The surge protectors in the prior art include gap surge protectors, and gap surge protectors, as the name implies, are surge arresters with gaps, and their function is mainly to break down the gap with a large current for conduction when there is an overvoltage. [0004] The announcement number is "CN2...
