The discharging gap of tradition overvoltage protection device is fixed, and can not adjust arcing distance according to the difference of environment for use, limitation is larger.
In addition, the design antifouling capacity of the current limiting element of traditional overvoltage protection device is poor, and insulation property are low.
Utility model content
The utility model proposes a kind of overvoltage protection device, solve the nonadjustable problem of overvoltage protection device discharging gap in prior art.
The technical solution of the utility model is achieved in that
A kind of overvoltage protection device, comprising: pillar insulator, current limiting element and mounting bracket, described pillar insulator and current limiting element are fixed on described mounting bracket; The top of described current limiting element is provided with lead-in wire, and its bottom is provided with ball discharge; Described mounting bracket is provided with adjustable striking ball and fixed striking ball; Described lead-in wire is connected with aerial insulated wire by wire clamp.
As preferably, described current limiting element is the current limiting element that large, medium and small full skirt combines.
As preferably, described ball discharge is provided with a little full skirt.
As preferably, described mounting bracket is stainless steel mounting bracket.
As preferably, the port of described lead-in wire is provided with block water skirt and heat-shrinkable T bush.
The beneficial effects of the utility model are:
By arranging adjustable striking ball and fixed striking ball on mounting bracket, the function automatically regulating discharging gap can be realized, so just can adjust different arcing distances according to the difference of the antifouling grade of different regions and environment humidity, the automatic arc extinguishing of current limliting original paper can be passed through after electric discharge, prevent aerial insulated wire from the generation of broken string and insulator sudden strain of a muscle road accident occurring, this discharging gap is solid and reliable, prevents the crust breakage caused owing to expanding with heat and contract with cold.
By current limiting element being designed to the form that large, medium and small full skirt combines, can not only Anti-ice-and-snow and bird pest, greatly can also increase antifouling capacity, increase insulated protective.
By increasing a little full skirt on the ball discharge of current limiting element, add the insulating properties of current limiting element.
The skirt that blocks water is set by the port carrying lead-in wire in current limiting element upper end, prevents rainwater from entering; Increase heat-shrinkable T bush in lead-in wire port, enhance protective, overvoltage protection device is become from open type closed, decrease accident point.
