Abstract

The invention provides a lightning protection system for a wind generating set, and relates to the field of lightning protection of wind generating sets. The lightning protection system for the wind generating set comprises a tower drum, a generator room is arranged at the top of the tower drum, a lightning protection base is arranged at the top of the generator room, and the generator set is fixedly connected to the bottom in the generator room. According to the lightning protection system for the wind generating set, thunder sound is recorded through a sound sensing element, when a lightning rod is pressed down by lightning stroke and thunder sound appears in a time period around the pressing work, the lightning stroke is recorded as one time, when the number of lightning stroke times reaches an early warning value, a maintenance signal is sent out, and the maintenance time is determined when a client receives the maintenance signal, so that maintenance resources are reduced; and meanwhile, a maintenance period is set, when the lightning protection system for the wind generating set is subjected to regular maintenance detection, a detection signal can be transmitted, a processing element receives the signal, and recorded data is sent to the client, so that the service life of the wind generating set is ensured, the maintenance work is more accurate, and excessive maintenance is avoided.

Description

technical field [0001] The invention relates to the technical field of lightning protection for wind power generators, in particular to a lightning protection system for wind power generators. Background technique [0002] A wind turbine is a kind of electrical equipment that can convert wind energy into mechanical energy, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are installed outdoors, and the actual height is relatively high. At the same time, wind turbines are installed on mountain tops or plain areas , Lightning strikes are prone to occur in thunderstorm weather, and it is necessary to use a lightning protection grounding device to protect the wind turbine. The lightning protection grounding device is usually composed of a lightning rod, a down conductor and a grounding device. The wire is conducted into the grounding device, and the grounding body in the grounding device is a conductor buried in the soil and directly in co...
