Abstract
The utility model relates to a gap adjusting mechanism for a 500kV pure air gap lightning arrester, which can resolve the problems that the pure air gap lightning arrester is relatively complicated in mounting and difficult in gap distance adjustment. The gap adjusting mechanism comprises one lightning arrester fixing upper clamping plate fixed on a tower cross arm, and a plurality of lightning arrester fixing lower clamping plates, wherein the left end of the lightning arrester upper clamping plate is provided with a discharge counter, etc. The gap adjusting mechanism for a 500kV pure air gap lightning arrester can be used for interruptedly or continuously adjusting the distance between an discharge gap upper electrode and a discharge gap lower electrode, and is reasonable in structure, convenient in mounting, easy in use and high in reliability.
Description
Technical field
The utility model relates to the lightning arrester field, is specially the pure air gap arrester clearance adjustment mechanism of a kind of 500kV.
Background technology
After the nineties, domestic and international 500kV transmission line adopted lightning arrester to do lightning protection device, obtained good effect.Usually wire (12) is to utilize line insulator (13) to hang in cross arm of tower (14) below.Lightning arrester has two kinds of versions: a kind of is insulator supporting gap type; A kind of is pure air gap type.Two kinds of lightning arresters respectively have pluses and minuses.With regard to its electric property and operation stability and operation detection property, pure air gap type lightning arrester is far superior to composite insulator supporting gap type.Can not affect system safety operation because any abnormal failure lightning arrester occurs, therefore adopt in large quantities pure air gap type abroad.Even all there is not composite insulator support type lightning arrester in the standard of IEC.But relative complex when installing owing to pure air gap type lightning arrester, clearance distance adjustment are difficult, bring certain difficulty to use.
Summary of the invention
Relative complex, the difficult problem of clearance distance adjustment provided the pure air gap arrester clearance adjustment mechanism of a kind of 500kV when the utility model was installed in order to solve pure air gap type lightning arrester.
The utility model is to adopt following technical scheme to realize: the pure air gap arrester clearance adjustment mechanism of 500kV, comprise the fixedly fixing lower plate of train wheel bridge and some lightning arresters of a lightning arrester being fixed on the cross arm of tower, lightning arrester fixedly train wheel bridge left end is provided with discharge counter, lightning arrester is the protruding cantilever that is provided with of train wheel bridge left end fixedly, the lightning arrester main body has been hung in the cantilever below, the lightning arrester body below is fixed with the discharging gap top electrode, be provided with some C type adjustment blocks between lightning arrester main body and the discharging gap top electrode, be fixed with the gap rod on the wire of discharging gap top electrode below, be fixed with the discharging gap bottom electrode on the rod of gap, the discharging gap bottom electrode comprises the bottom electrode supporting bracket that is supported on rod top, gap, utilize the Height Adjustment bolt to be supported with bottom electrode discharging rod supporting bracket on the bottom electrode supporting bracket, be fixed with the bottom electrode discharging rod on the bottom electrode discharging rod supporting bracket.
Adjusting mechanism is divided into two parts, and the some C type adjustment blocks between lightning arrester main body and the discharging gap top electrode are adjusted the height of discharging gap top electrode as the coarse adjustment part by the quantity that changes C type adjustment block; The Height Adjustment bolt is as the fine setting part, by turning the height of the continuous trickle adjustment bottom electrode discharging rod of Height Adjustment bolt; Thereby realize the adjustment of discharging gap.C type piece is according to calculative determination quantity, and the Height Adjustment bolt is according to the calculative determination height, and distance is adjusted suitable rear locking Height Adjustment bolt.
The beneficial effects of the utility model are as follows: utilize a clearance adjustment mechanism that comprises coarse adjustment part and fine setting part, realized the distance between interruption or continuous setup discharging gap top electrode and the discharging gap bottom electrode.The utility model is rational in infrastructure, easy for installation, easy-to-use and reliability is high.
