Technical field
The utility model relates to a kind of electric power system controller switching equipment, specifically is meant a kind of lightning protection pillar insulator.
Background technology
Prevent both at home and abroad at present that the measure that 1-35KV suspended insulated guide wire lightning-caused breaking is taked from mainly containing suspended insulated guide wire installation oxide lightning arrester, installs arc-preventing metal utensil in the post insulator load side.The former uses lightning arrester, though protection effect is good, and the construction and installation complexity, investment is big.A kind of preventing arc puncture gold utensil that is used to prevent the suspended insulated guide wire lightning-caused breaking of the latter, it mainly comprises penetrating cable clamp, arcing electrode, ground connection arc electrode and insulating shield etc., there is the shortcoming that is subject to ring network power supply load side variable effect in this mode, and can only play the preventing arc effect.
For this reason, at present, occurred a kind of lightning protection pillar insulator on the market, post insulator and arc-preventing metal utensil have been united two into one, as Chinese patent publication number CN101325104B, its structure comprises insulating shield and is arranged at the clamp gold utensil that is made of upper holder block and lower lock block in the insulating shield, this clamp gold utensil side connects starting rod, and this clamp gold utensil lower end connection insulator, and insulator is arranged with antifouling full skirt outward, the insulator lower end is provided with down the steel pin, and the lower end of starting rod is near steel pin setting down.But there is following defective in the lightning protection pillar insulator of this structure:
(1) upper holder block of clamp gold utensil and lower lock block adopt clamp nut and are equipped with the jack panel lead that clamps and puncture, in the process for the clamping puncture lead that prevents upper holder block and lower lock block, damage wires, need set the torque of wrenches of a scope according to factors such as the cross section of lead and weather temperature, and in actual mechanical process, often because workman's operate miss, torque of wrenches is excessive or too small, and cause lead impaired or lead in clamping process not reach best electro-contact effect, have a strong impact on the performance of lightning protection pillar insulator;
(2) antifouling umbrella skirt construction is provided with unreasonable, its back side is designed for level, in use, the back side of antifouling full skirt tends to pile up dirts such as dust, but in rainwater weather, the antifouling full skirt structure of this level design can't drain into rainwater the back side of antifouling full skirt, and to washing away of dirt, antifouling ability is relatively poor.
(3) the line ball mode is unreasonable, needs periodic maintenance.Lead compresses and adopts 2 nuts
Lock, if lead expands with heat and contract with cold when changing, the contact-making surface of lead and puncture tooth will have the space, causes contact-making surface generation oxidation reaction, and contact resistance increases; Influence result of use.Need the attendant regularly to safeguard.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provide a kind of can guarantee to install the time clamp gold utensil be in the best with lead and contact unlikely damage wires of effect and the lightning protection pillar insulator non-maintaining, that anti-fouling effect is fabulous.
For achieving the above object, the technical solution of the utility model is to comprise insulating shield and be arranged at the clamp gold utensil that is made of upper holder block and lower lock block in the insulating shield, this clamp gold utensil side connects starting rod, and this clamp gold utensil lower end connects insulator, the insulator lower end is provided with down the steel pin, and the lower end of starting rod is near steel pin setting down, described upper holder block is connected with the effective torque nut by bolt with lower lock block, constitutes the effective torque nut and rotates and drive that upper holder block is relative with lower lock block to be clamped or unclamp action.Realize the clamping of upper holder block and lower lock block and unclamp by the effective torque nut is set, when mounted, select the effective torque nut of form-fit torque parameter according to factors such as the cross section of lead and weather temperature, the puncture force and the lead pull-off force that can guarantee upper holder block and lower lock block are constant, guarantee that lead is in best contact condition, operate miss in the time of preventing again that the workman from installing, damage wires.
Further being provided with is that an end of described bolt is fixed on the lower lock block, and described upper holder block is provided with the through hole adaptive with bolt, and the outer end of described bolt passes through hole, and is threaded the effective torque nut is set.Originally be set to concrete a kind of way of realization of above-mentioned setting, the utility model bolt also can be fixed on the upper holder block by an end certainly, and corresponding lower lock block is provided with the through hole adaptive with bolt, locks by the effective torque nut again.In addition, also can adopt lower lock block and upper holder block all to be provided with through hole, and pass through wherein by bolt, and at least one end connection effective torque nut in two outer ends of bolt, above-mentioned these modes all belong to the identical design of the present invention.
Further be provided with is to be arranged with disk spring on the bolt between described effective torque nut and the upper holder block.By this setting, adopt the clamping force that lead is applied of dish-shaped pad upper holder block and lower lock block to carry out the sufficient force compensation, remedy that lead expands with heat and contract with cold and long-time running and the creep problem takes place, thereby effectively guarantee the contact condition of lead the best.And be in operation and do not need periodic maintenance.
Further being provided with is that described bolt is provided with two, and the two space is provided with.This is provided with and adopts diaxon location upper holder block and lower lock block, guarantees the stability that compresses.
Further being provided with is that the lower surface of described upper holder block and the upper surface of lower lock block are provided with some grooves, is provided with the puncture tooth in this groove.
Further being provided with is that described insulator is gone back fixed cover outward and is provided with antifouling full skirt, and the lower surface of this antifouling full skirt is the taper surface setting.By this setting, because the mobile performance of rainwater, by this setting, can guide to the lower surface that rainwater flow into antifouling full skirt, thereby the dirt that will be piled up in herein washes away, thereby reduced the corrosion of pollutant full skirt, anti-soil power is strong, is fit to coastal and high pollution area.
Further being provided with is that described starting rod is with an insulating sleeve outward.Described starting rod is provided with starting rod extinguishing arc head near a side of this time steel pin.Following steel pin is provided with down steel pin extinguishing arc head near a side of starting rod.
The utility model has the advantages that when guaranteeing to install that clamp gold utensil and lead are in bestly contacts the unlikely again damage wires of effect, but also has good antifouling effect, non-maintaining advantage.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
