Abstract
The utility model discloses a kind of lightning protection system for wind energy turbine set, including: fall insurance, spark gap and drain earth lead, described fall insurance, described spark gap and described drain earth lead are sequentially connected with according to the direction from the top of wind power equipment terminal tower to bottom, wherein, one end of described fall insurance connects the upper connecting line of described wind power equipment terminal tower, the other end of described fall insurance connects one end of described spark gap, and the other end of described spark gap connects described drain earth lead.Thus, in view of wind power equipment terminal tower spark gap is arranged on ground connection one side of corresponding fall insurance, i.e. fall insurance is arranged on the top of spark gap, the most once certain spark gap breaks down, by being disconnected by connected fall insurance, it can be carried out malfunction elimination, and not affect the properly functioning of remaining Fan Equipment.
Description
Technical field
This utility model relates to field of wind power equipment, especially designs a kind of lightning protection system for wind energy turbine set.
Background technology
Wind energy is as the regenerative resource of a kind of cleaning, and its amount of accumulateing is huge, is increasingly paid attention to by countries in the world.So
And, at thunderstorm season, outdoor wind power equipment is highly prone to thunderbolt impact and therefore damages, to this end, these wind power equipment (examples
As: transformator) it is generally provided with lightning arrester.
Wind energy turbine set is in actual motion, and once the lightning arrester of certain transformer terminal tower itself breaks down, need to be to whole
Returning line outage to carry out troubleshooting, power failure range is big, has severely impacted the generating efficiency of wind energy turbine set.
And, when earth fault occurs in lightning arrester, maintenance work personnel can not failure judgement point accurately and rapidly
Position, troubleshooting efficiency is the lowest.
Utility model content
This utility model is intended to solve one of above-mentioned technical problem of the prior art the most to a certain extent.To this end,
A purpose of the present utility model is to propose a kind of lightning protection system for wind energy turbine set.
According to the lightning protection system for wind energy turbine set of the present utility model, including: fall insurance, spark gap and drain ground connection
Line, described fall insurance, described spark gap and described drain earth lead according to the top from wind power equipment terminal tower to bottom
Direction is sequentially connected with, and wherein, one end of described fall insurance connects the upper connecting line of described wind power equipment terminal tower, described in fall
The other end of insurance connects one end of described spark gap, and the other end of described spark gap connects described drain earth lead.
According to lightning protection system of the present utility model, the spark gap of wind power equipment terminal tower is arranged on corresponding fall insurance
Ground connection one side, i.e. fall insurance are arranged on the top of spark gap, and once certain spark gap breaks down, can be by being attached thereto
The fall insurance connect disconnects and it is carried out malfunction elimination, and does not affect the properly functioning of remaining Fan Equipment.Meanwhile, when lightning-arrest system
When earth fault occurs in system, by fall insurance is disconnected one by one, corresponding spark gap is investigated one by one, can accurately, quickly
Positioning both ground trouble point, ground, improves the troubleshooting efficiency of wind energy turbine set.
It addition, can also have a following distinguishing feature according to the lightning protection system for wind energy turbine set of the present utility model:
In examples more of the present utility model, the described lightning protection system for wind energy turbine set, also include chopper, its string
It is associated between upper connecting line and the described fall insurance of described wind power equipment terminal tower.
In examples more of the present utility model, described spark gap and described drain earth lead are carried out even by device clamp
Connect.
