Abstract

Provided is a built-in column type current limiter consisting of a zinc oxide resistor disc, an insulation core rod, an insulated umbrella skirt, a metal support, a clamp fitting and a steel foot. The metal support is led out of an insulation sleeve from the inner core, one end is provided with an arc ignition ball and an identifier that are corresponding to an arc ignition rod on the clamp fitting to form an external string discharge channel. When the lightning stroke threatens, the discharge channel discharges at first, due to the role of the zinc oxide resistor disc, the generation of power frequency freewheeling can be prevented, so that the insulator pollution flash is prevented, and the insulated lead is prevented from being burnt. The insulator function and the lightning arrester function are ingeniously combined, so that the lines are compact and beautiful, and the installation is convenient.

Description

Built-in pillar current limiter
Technical field:
The present invention relates to power overhead network safe operation field, can take precautions against and blow insulated conductor because of damage to crops caused by thunder, make aerial line Road pollution flashover accident significantly reduces.
Background technology:
Overhead transmission line using insulated conductor if do not taken lightning protection measures, once suffer from mines to break;At present, though respectively Class lightning-protected product with measure the more, but all has advantage and disadvantage;Just because of this, my department have developed with great concentration built-in pillar current limiter, wishes The damage to crops caused by thunder problem hoping overhead transmission line is taken on a new look.
Content of the invention:
Built-in pillar current limiter, by zinc oxide resistance sheet, insulation mandrel, insulating coating, metal rack, clamp gold utensil and steel Foot etc. is constituted;Metal rack therein by inner core from insulating coating draw, one end equipped with striking ball and mark, and with clamp gold utensil On arc ignition bar correspond to, form outer discharge channel of going here and there.
The technical scheme is that:
Built-in pillar current limiter (see Fig. 1), is propped up by the gold utensil of line containing toothholder 1, arc ignition bar 1.1, striking ball 2, mark 3, metal Frame 4, zinc oxide resistance sheet 5, insulation mandrel 6, compound full skirt 7, screw 8, steel foot 9, insulating boot 10 are constituted;Zinc oxide resistance sheet group The Du Lidun set closing is connected on insulation mandrel 6, contacts closely with steel foot by the lower aluminum head that the effect of screw 8 makes Du Lidunli, multiple Close full skirt 7 and be wrapped in whole core body, metal rack therein is drawn from insulating boot by inner core, and its one end is equipped with striking ball and mark Know, and corresponding with the arc ignition bar on clamp gold utensil, form outer string discharge channel, when having thunderbolt infringement, discharge channel first discharges, by In the effect of zinc oxide resistance sheet, power frequency continued flow is stoped to produce it is therefore prevented that insulator contamination, it is to avoid insulated conductor is blown.
Another kind of built-in pillar current limiter (see Fig. 2), the non-stripping of insulated conductor is installed on clamp gold utensil, insulated conductor bottom It is provided with long bonding jumper, two metal racks are drawn from insulating coating by inner core, and its termination is respectively provided with striking ball and mark, and point Not corresponding with bonding jumper, form outer discharge channel of going here and there.
Brief description:
Fig. 1 is built-in pillar current limiter assembling figure.
Fig. 2 is another kind of built-in pillar current limiter assembling figure.
Embodiment
Built-in pillar current limiter is arranged on the iron cross arm of 10kV distribution line, energy insulating supporting aerial line, can be effectively anti- Aerial line is blown in only thunderbolt;On clamp gold utensil, arc ignition bar is towards supply load side.
Built-in pillar current limiter, insulator function and spark gap function carry out ingenious combine, make circuit compact attractive in appearance, and It is convenient to install again;
The metal rack drawn in core body constitutes discharge channel, due to series gap with the arc ignition bar clamp gold utensil Electric discharge pressure low compared with normal the flashover voltage of the insulator, therefore, this discharge channel has leading discharging condition, simultaneously the electricity in core body Resistance piece have non-linear, can limit lightning surge stop power frequency continued flow produce, make aerial condutor exempt from scaling loss.
