The utility model is an overhead insulated wire lightning protection device, which includes an insulated circuit, an insulator on the insulated circuit is used as a support, a connecting plate is fixed on the lower end of the insulator by bolts, and a non-linear current limiting device is fixed on the other end of the connecting plate by bolts Components, the upper end of the nonlinear current-limiting element under the insulating line is provided with a drainage bracket, a lightning rod is arranged on the drainage bracket, and a drainage block is installed on the insulating line corresponding to the drainage bracket, that is, the insulating layer is placed on the insulated wire where the drainage block is set. Peel it off, and stick a conductive drainage block on it. With the above structure, the utility model has the following advantages: when the overhead insulated wire encounters a lightning current impact, the high voltage of the lightning current first breaks down the series gap between the wire and the drainage bracket, and guides the lightning current to the current limiting element through the lightning rod , by limiting the lightning residual voltage above the overvoltage, and cutting off the power-frequency continuous flow caused by lightning current, preventing the overhead insulated wire from being disconnected by lightning, and fundamentally solving the occurrence of lightning disconnection accidents.
Description
Technical field
The utility model relates to a kind of lightning protection device, relates in particular to a kind of insulated overhead line overvoltage lightning protection device.
Background technology
A large amount of suspended insulated guide wire circuits that adopt have solved tree line contradiction and circuit corridor contradiction effectively in the 10KV distribution network.But the statistical magnitude of insulated circuit generation lightning-caused breaking and insulator breakdown accident is in rising trend in recent years, and sharply rises along with the increase of insulated conductor line length, has become the main root of serious threat line security operation.Present existing insulated overhead line overvoltage protection; zinc oxide arrester is arranged; overhead ground wire etc., but there are the following problems respectively: and the zinc oxide arrester protection range is little, increases protection range as need; must on every electric pole, install; increased cost of investment on the one hand, also needed to install additional on original circuit affiliated facilities such as cross-arm, difficulty of construction is big; this mode has superiority for the protection of power consumption equipment class, but should not adopt on distribution line.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency a kind of aerial insulated wire lightning protection device is provided.
The technical solution of the utility model is as follows:
A kind of aerial insulated wire lightning protection device, comprise insulated circuit, with the insulator on the insulated circuit is support, lower end at insulator is provided with connecting plate by bolt, the other end at connecting plate is provided with non-linear current limiting element by bolt, non-linear current limiting element upper end below insulated circuit is provided with drainage stent, drainage stent is provided with lightning rod, the drainage piece is set on the insulated circuit of drainage stent correspondence, promptly at the insulated conductor place that the drainage piece is set with the insulating barrier strip off, conductive drainage piece on the card.
Above-mentioned aerial insulated wire lightning protection device also is provided with drainage needle on the drainage piece.
The utility model adopts said structure, the utility model has following advantage: when suspended insulated guide wire meets the lightning current impact, the high voltage of lightning current at first punctures the series gap between lead and the drainage stent, guide lightning current into current limiting element by lightning rod, by it thunder and lightning residual voltage is limited on the overvoltage, and cut off the power frequency continued flow that lightning current causes, prevent that aerial insulated wire from suffering lightning-caused breaking, fundamentally solve the generation of lightning-caused breaking accident, the drainage needle that is provided with on the drainage piece simultaneously can be accelerated lightning current and flow to current limiting element.
