Abstract
The utility model relates to a transmission line type lightning protection counter-net type air gap lightning arrester which comprises a supporting frame, a lightning protection counterattack net, the connection point of the supporting frame and the lightning protection counterattack net, a conducting wire cross arm, a grounding wire of the supporting frame and the conducting wire cross arm, an insulator string, a conducting wire, the insulating distance of the lightning protection counterattack net and the conducting wire, a reinforced concrete tower, the connection point of the supporting frame and the reinforced concrete tower, etc. When the conducting wire cross arm bears lightning over voltage, the lightning over voltage acting on the conducting wire between the conducting wire cross arm and the lightning protection counterattack net is enabled to be minimal for the reason that the conducting wire cross arm is in equipotential connection with the supporting frame and the lightning protection counterattack net, and accordingly, the utility model can achieve the function of lightning protection.
Description
Title of the present utility model is: the anti-thunder and lightning counterattack of transmission line type net formula air gap arrester.
The utility model is used for the shocking preventing technology field of transmission line.
The major defect of existing transmission line type lightning arrester has two, and the first belongs to charging operation equipment, complex structure, construction, operation maintenance difficulty; It two is cost height, is difficult to large scale application.
The purpose of this utility model is that the anti-thunder and lightning counterattack of transmission line type net formula air gap arrester will be provided, and this lightning arrester can overcome the existing existing above-mentioned defective of transmission line type lightning arrester.
Design of the present utility model is to realize like this, it comprises support, anti-thunder and lightning counterattack net, the tie point of support and anti-thunder and lightning counterattack net, the lead cross-arm, the earth connection of support and lead cross-arm, insulator string, lead, air gap insulation distance between anti-thunder and lightning counterattack net and the lead, the armored concrete shaft tower, ten parts such as tie point of support and armored concrete shaft tower, it is characterized in that support and anti-thunder and lightning counterattack net are connected with lead cross-arm equipotential, anti-thunder and lightning counterattack net is positioned at the below of lead, lead has the air gap insulation distance that satisfies insulating requirements between anti-thunder and lightning counterattack net and the lead between lead cross-arm and anti-thunder and lightning counterattack net.When being struck by lightning in the head of mast of transmission line, when causing the lead cross-arm to bear lightning overvoltage, because the lead cross-arm is connected with support and anti-thunder and lightning counterattack net equipotential, make the lightning overvoltage on the lead that acts between lead cross-arm and the anti-thunder and lightning counterattack net minimum, thereby play lightning-arrest effect.In addition, when insulator string fell the string accident, support of the present utility model and anti-thunder and lightning counterattack net can also have to be accepted because of insulator string falls the lead that string falls, and prevented the fall function on ground of lead.
Therefore, than existing transmission line type lightning arrester, the utlity model has following remarkable advantage:
1, do not belong to charging operation equipment, design, manufacturing, construction and installation, operation maintenance are easy, lightning-arrest better effects if.
2, can be only with made such as galvanized steel or stainless steel, copper, aluminium alloys, simple in structure, the mechanical strength height, long service life, low price is convenient to large scale application.
3, can be applied to the transmission line of existing various electric pressures, have wide range of applications.
4, when insulator string falls the string accident, can have and prevent the fall function on ground of lead, make transmission line more safe and reliable.
Below in conjunction with accompanying drawing the utility model is specifically described.
