Abstract
The invention particularly relates to a gap adjusting mechanism for a 500-kV pure air gap surge arrester, which solves the problem that the pure air gap surge arrester is relatively difficult to mount, and a gap distance is difficult to adjust. A distance between a top electrode and a bottom electrode of a discharging gap can be intermittently or continuously adjusted through the gap adjusting mechanism which comprises a coarse adjusting part and a fine adjusting part. The gap adjusting mechanism provided by the invention has the advantages of reasonable structure, convenience in installation, easiness in utilization and high reliability.
Description
Technical field
The present invention relates to the lightning arrester field, be 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 occuring, 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 present invention installed in order to solve pure air gap type lightning arrester.
The present invention adopts 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.
Beneficial effect of the present invention is 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 present invention is rational in infrastructure, easy for installation, easy-to-use and reliability is high.
