Circuit breaker trip；Second is that there is the electric discharge of breakdown in insulation, the part of conductor also will appear hot melten type fusing failure, insulation
Sub and breakdown fitting has the failure damaged in succession.
Power overhead network is generally made of bar (tower), conducting wire, insulator, in which: one end of insulator is fixed on bar
On (tower), other end support, fixed conducting wire.Insulator plays two basic roles in electric power overhead molded line road, that is, supports, is solid
Determine conducting wire and electrical body and ground connection isolated insulation.In normal working conditions, insulator can play support, fixed conducting wire and band
The effect of electric body and ground connection isolated insulation, but lightning stroke, operation is occurring or when Frequency Transient Overvoltage, it is defeated, distribution line is general
It will appear tripping property failure, it is also possible to cause decreasing insulating or the broken stock that breaks because electric discharge causes insulator surface flashover
Accident.
Therefore, a kind of lightning protection line insulator with pressure and discharging gap function how is provided, to avoid exhausted
The accident of edge and conducting wire by flashover and broken string is current those skilled in the art technical problem urgently to be resolved.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of with the lightning protection route pressed with discharging gap function
Insulator, the accident to avoid insulator and conducting wire by flashover and broken string.
In order to achieve the above object, the invention provides the following technical scheme:
A kind of lightning protection line insulator with pressure and discharging gap function, including insulator body further include

Seat be fixedly connected, the pedestal connect with ground terminal and the discharge ball setting on the pedestal, the discharge ball with it is described
Starting rod gap setting.
Preferably, above-mentioned grading ring is outer even formula grading ring.
Preferably, metallic channel and upper holder block are provided in above-mentioned insulator body, conducting wire is passed through from the metallic channel, institute
It states upper holder block to be fixed by screws in the insulator body, and the conducting wire is fixed in the metallic channel.
Preferably, it is arranged fluted on above-mentioned upper holder block, the groove and the metallic channel are to positive setting.
Lightning protection line insulator provided by the invention with pressure and discharging gap function, including insulator sheet
Body further includes grading ring, starting rod, pedestal and discharge ball, wherein the grading ring is set in the insulation of the insulator body
On cap, the side of the bottom of the insulator body is arranged in the starting rod, and the bottom of the insulator body passes through insulation
Bar is fixedly connected with the pedestal, and the pedestal is connect with ground terminal and the discharge ball is arranged on the pedestal, described to put
Electric ball and the starting rod gap setting.When lightning surge occurs, be grading ring on insulator cap first by overvoltage into
After row is uniformly distributed extension flashover path, then by the lower curve through the downward metal of starting rod, i.e. gap between discharge ball is put
The power frequency arc of electricity, connecting discharges overvoltage energy to ground terminal, to protect insulator and insulated conductor not by flashover and damage
Wound avoids insulator and conducting wire by the accident of flashover and broken string (broken stock).
