Abstract
The utility model relates to a transmission line type equipotential ring-typed air space lightning arrester which comprises an equipotential ring, a lightening protection counterattack net, the connection point of the equipotential ring and the lightening protection counterattack net, a connecting head of the equipotential ring, a conducting wire cross arm, the connection point of the equipotential ring and the conducting wire cross arm, an insulator string, a conducting wire, an air gap insulated distance between the equipotential ring as well as the lightening protection counterattack net and the conducting wire, a transmission line tower, a grounding wire, etc. When the conducting wire cross arm bears lightning over voltage, because the conducting wire cross arm is in equipotential connection with the equipotential ring and the lightening protection counterattack net, the lightning over voltage acting on the conducting wire between the conducting wire cross arm and the lightening protection counterattack net is enabled to be minimal for achieving the action of lightning protection.
Description
Title of the present utility model is: transmission line type equipotential ring type 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 transmission line type equipotential ring type 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 the equipotential ring, anti-thunder and lightning counterattack net, the tie point of equipotential ring and anti-thunder and lightning counterattack net, the connector of equipotential ring, the lead cross-arm, the tie point of equipotential ring and lead cross-arm, insulator string, lead, air gap insulation distance between equipotential ring and anti-thunder and lightning counterattack net and the lead, electric power line pole tower, 11 parts such as earth connection, it is characterized in that equipotential ring 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 is between lead cross-arm and anti-thunder and lightning counterattack net, the equipotential ring has the air gap insulation distance that satisfies insulating requirements around conductor arrangement between equipotential ring and anti-thunder and lightning counterattack net and the lead.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 equipotential ring 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, equipotential ring 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, simple in structure, 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, 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.
