Description
Technical field
The present invention relates to the lightning arrester field, relate in particular to a kind of Transmission Line Arrestor.
Background technology
Traditional insulator supports gap Transmission Line Arrestor structure: the insulator in lightning arrester and support gap is two independently individualities, lightning arrester and insulator link by bolt, on insulator, fix two discharging gap balls, air gap and compound inslation gapless metal-oxide lighting arrester are in series, the characteristic of lightning arrester is decided by the size in gap, the size of ball discharge, the gaseous state on every side and the voltage-current characteristic of lightning arrester, thereby, traditional insulator supports the gap Transmission Line Arrestor and has following defective: 1, the last ball discharge of discharging gap ball is guided to earth terminal with high pressure, last ball discharge has the high pressure floating potential, easily results in personal injury caused by an accident.2, the setting angle of ball discharge is a zero degree to horizontal direction, because clearance distance is less, easily causes gap shorting when drenching with rain with accumulated snow.3, the lightning arrester of this structure only can be used for the lead (straight line pole) of high-voltage conducting wires above the shaft tower cross-arm, and the shaft tower (disconnected link rod) of high-voltage conducting wires below shaft tower can't be installed.4, support the supporting bracket of discharging gap ball, adopt organic materials such as SMC, weatherability is poor, and service life is short out of doors, when drench with rain or accumulated snow after, supporting bracket may take place to be punctured, sphere gap does not discharge.5, the supporting bracket of lightning arrester and support discharging gap is for dividing body structure, and volume is big, site operation inconvenience.
Summary of the invention
In order to overcome the above-mentioned defective that conventional insulators supports the gap Transmission Line Arrestor, the invention provides a kind of composite insulator support fixation gap Transmission Line Arrestor.
The technical scheme that the present invention is adopted for achieving the above object is:
Scheme one, composite insulator support fixation gap Transmission Line Arrestor, comprise lightning arrester body, lead and insulating cover are installed in the lightning arrester body upper end, insulated conductor is drawn via the insulating cover upper end, composite insulator is installed in the lightning arrester body bottom, is provided with tap between lightning arrester body and the composite insulator, and last sparking electrode is connected with tap, ball discharge is installed in last sparking electrode lower end, and ball discharge down is installed on the composite insulator.
