Description
Technical field
The utility model relates to a kind of isolator lightning arrester, particularly a kind of arc blowing type isolator lightning arrester.
Background technology
Along with the development of urban economy, more and more higher to the requirement of distribution line reliability.But distribution line branch is many, topological structure is complicated, and insulation level is low, is very easily subject to lightning overvoltage harm, affects user's normal power supply.Lightning arrester is safeguard measure conventional on distribution line, that effectively prevent lightning overvoltage infringement.China is used lightning arrester comparatively widely to adopt the mode in parallel with insulator to install at present.This pattern to install and use device many, increased the cost of equipment, and needed larger space, increased the difficulty of global design.Circuit is beautified requirement more and more higher now, the integrated design of lightning arrester and insulator is more attractive in appearance.And existing lightning arrester cannot complete arc extinguishing automatically, easily form power frequency continued flow and cause ground short circuit fault.
Summary of the invention
The utility model provides a kind of arc blowing type isolator lightning arrester, cannot automatic distinguishing power frequency continued flow electric arc to solve in prior art isolator lightning arrester, and the problem that tower head space availability ratio is low.
The technical scheme that the utility model is taked is: a kind of arc blowing type isolator lightning arrester, comprise insulator umbrella, insulator umbrella upper end is connected with wire clamp, and insulator umbrella lower end connects plug upper end, plug lower end connects lightning arrester top, lightning arrester bottom connection metal base.Described lightning arrester comprises a plurality of chamber electrodes, and a plurality of chamber electrodes are wrapped with insulating sleeve, and the gap between a plurality of chamber electrodes forms arc control device, and described arc control device both sides respectively have fumarole.
Described chamber electrode is ball-type hardware.
Upper end and the gap between plug lower end at the chamber electrode at top form arc control device; Upper end and the gap between a chamber electrode above it at the chamber electrode of bottom form arc control device, are positioned at the lower end connection metal base of the chamber electrode of bottom.
Described insulating sleeve comprises plug lower end.
Described metab is provided with hold-down nut.
A kind of arc blowing type isolator lightning arrester of the utility model, compares with existing lightning arrester, the high temperature producing by electric arc between chamber electrode, and the air in heating arc control device, utilizes the high velocity air forming that the interelectrode electric arc of chamber is blown disconnected.The excessive problems such as counterattack that cause of power frequency continued flow or residual voltage have been avoided.And lightning arrester of the present utility model and insulator are integrated, not only saved tower head space, reduced shaft tower design difficulty, also made tower head more attractive in appearance.
