Abstract
The utility model relates to a lightning protection device for transmission lines, which is composed of a lightning rod, a support frame, a base, etc., wherein, the base is fixed on the top board of the support frame, the lightning rod is inserted in a cylindrical iron cylinder which is arranged on the base, the lightning rod can be provided with double rods and can be provided with a single rod, and the included angle between the double rods is 25.3 DEG. The single rod is perpendicular to a backplane. The utility model has good lightning protection effect, 100% of upgoing thunder can be eliminated, and the utility model has a restriction on main discharge current of downgoing thunder. The utility model has the advantages of large protection range, convenient installation and construction.
Description
The utility model belongs to high voltage technique, particularly the shocking preventing technology field
The lightning protection device that present people adopt on transmission line still adopts the lightning rod of Franklin invention, and this is directly to be fixed on the iron tower, does not also use special transmission line lightning protection device.Although lightning rod can attract thunder and lightning effectively, its harm of high induction voltage excessively is bigger, therefore protects effect good inadequately, and installation is also inconvenient.
The utility model is exactly the lightning protection device effect shakiness at the current power transmission circuit, and the shortcoming that installation does not just make provides a kind of installation easy, the lightning protection device of the transmission line that lightning protection effect is good.
The purpose of this utility model realizes by following scheme.
The lightning protection device of this transmission line is sat back and waited by lightning rod, support, the end and forms that support is made up of two half-cylindrical iron plates, and respectively there are two edges on half-cylindrical iron plate both sides; Some screws are respectively arranged on the edge, two half-cylindrical iron plates connect with screw rod, nut by screw, an angle bar is respectively welded in two semicircle iron plate outsides, angle bar is longer than cylinder, stretch out the cylinder end face, the angle bar end face respectively welds an iron plate, iron plate is parallel with the cylinder end face, and iron plate is provided with some screws.
Sit and be made of base plate and lightning-arrest syringe at the end of the utility model lightning protection device; also be provided with screw on the base plate and iron plate passes through Bolt Connection; syringe is made up of two cylindrical work durms; the plane of two syringe compositions is vertical with base plate; two syringes equate with angle between the base plate, and the angle between two syringes is 25.3 °.
The employed lightning rod of the utility model lightning protection device is that semiconductor lightning rod, lightning rod insert respectively in two syringes, is screwed.
As required, the end of the utility model transmission line lightning protection device seat also can be made up of base plate and a cylindrical work durm, and cylindrical work durm is vertically welded in base plate central authorities, and the semiconductor lightning rod inserts in the work durm and with screw lightning rod fixed.
Have better lightning protection effect by theory analysis and field operation experiences proof the utility model transmission line lightning protection device, can 100% eliminate up thunder; Lightning stroke process had consumption; To the restricted effect of the discharging current of descending thunder, also have that protection range is big, the easy advantage of installation
Accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 are the utility model embodiment schematic diagram.Accompanying drawing 1, accompanying drawing 2 are the supporting structure schematic diagram, and Fig. 3 is a bitubular crosspointer base plate schematic diagram.
An embodiment of the lightning protection device of the utility model transmission line is shown in attached Fig. 1 and 2: be made up of two half-cylindrical iron plates 1; respectively there are two edges 3 on half-cylindrical iron plate both sides; two pairs of screws are arranged on the edge 3; two semicolumn iron plates are by the screw screw rod; nut connects; an angle bar 4 is respectively welded in two semicircle iron plate outsides; angle bar 4 is than the Gao Yaochang of cylinder iron plate; stretch out the cylinder end face; iron plate 5 of angle bar end face weldering; iron plate 5 is parallel with the cylinder end face, and iron plate 5 is provided with two pairs of screws 6, as shown in Figure 3; the end, sit 2 by base plate 7; lightning-arrest syringe 8 constitutes, and clothing plate 7 also is provided with two pairs of screws and matches with iron plate 5, and is fixed together by the spiral shell inspection; syringe 8 is made up of two cylindrical work durms; the plane that two syringes 8 are formed is vertical with base plate 7, and two syringes equate with angle between the base plate 7, and the angle between two syringes is 25.3 °; the semiconductor lightning rod inserts respectively in two syringes 8, and is screwed.
