Abstract
The utility model provides a novel lightning-proof overvoltage protector of a line insulator, which belongs to the technical field of the component of a power supply line. The utility model aims at solving the problems that the phenomena of aging and corrosion are easy to occur and the use is influenced because a conductive drainage ball of a traditional lightning-proof overvoltage protector of a line insulator and a drainage ball of a current limiting element are exposed to the outside. A current limiting element adopted by the novel lightning-proof overvoltage protector of the line insulator is an insulated current limiting element in which a conductive drainage ball and a drainage ball of a current limiting element are covered in an insulating sleeve body, and the conductive drainage ball and the drainage ball of the current limiting element are positioned on the same longitudinal axis. The novel lightning-proof overvoltage protector of the line insulator has a simple and practical structure and is suitable for preventing a line of an overhead insulated conducting wire of a power supply network from being damaged by lightning stroke.

Summary of the invention
In order to overcome the deficiency of prior art, it is exposed outside to solve existing line insulator lightning protection overvoltage protection device conduction drainage ball and current limiting element drainage ball, is prone to aging, corrosion, the problem that influence is used.The purpose of the utility model provides a kind of simple and practical, and is ageing-resistant anticorrosive, to connect supply line safe and reliable to operation, application life is long, installs and uses easy new-type line insulator lightning protection overvoltage protection device.
The utility model addresses the above problem the technical scheme that is adopted:
A kind of novel line insulator lightning protection overvoltage protection device, it is provided with: conduction drainage ball, conduction drainage ball connect electric wire clamping plate, current limiting element drainage ball, current limiting element, connecting struts plate.It is characterized in that: current limiting element is the insulation current limiting element that ladle cover conduction drainage ball and current limiting element drainage ball in the insulation body.
Above-mentioned novel line insulator lightning protection overvoltage protection device, said conduction drainage ball and current limiting element drainage ball are positioned on the same longitudinal axis.
Above-mentioned novel line insulator lightning protection overvoltage protection device, said connecting struts plate are that pair of L t shore plate is by connecting the adjustable connecting struts plate of height that screw is located by connecting.
Above-mentioned novel line insulator lightning protection overvoltage protection device is shaped on the plate body of arbitrary L t shore plate of said connecting struts plate and installs the rectangular adjustment hole that connects screw.
When the utility model uses, the same with existing line insulator lightning protection overvoltage protection device, this novel conduction drainage ball connecting cleat is linked on supply lines, screw gets final product the load of connecting struts plate in the insulator bottom of existing line.
Because technique scheme has been adopted in the utility model design, it is exposed outside to have solved existing line insulator lightning protection overvoltage protection device conduction drainage ball and current limiting element drainage ball effectively, is prone to aging, corrosion, the problem that influence is used.Also show that through testing result on trial for several times it compared with prior art has simple and practical; Ageing-resistant anticorrosive, to connect supply line safe and reliable to operation, application life is long; Install and use advantages such as easy, be applicable to that the strick precaution of supply network suspended insulated guide wire circuit suffers lightning damage.
