Abstract
The utility model relates to a prestress electric pole with a ground wire, which comprises a pole body, the ground wire and a lightning rod arrester fixedly arranged on the top end of the pole body. The ground wire is arranged among prestress main ribs inside the electric pole; the lead-wire top end of the ground wire is connected with the lightning rod arrester; and the lead-wire root end of the ground wire is connected with a grounding downlead wire. In the utility model, a built-in lightning-protection grounding lead-wire electric pole is connected with the arrester and the downlead wire, so as to enable the electric pole to achieve better lightning-protection effect when the electric pole is applied to the line, and avoid the electric power facilities and the related devices from being damaged due to lightning, and overcome the shortcomings that the electric pole uses an external lightning-protection lead wire or an external crawling ladder as the lightning-protection lead wire; the prestress electric pole has advantages of attractiveness, durableness, no loss caused by corrosion, low manufacturing cost, maintenance free and being convenient to install.
Description
Technical field
The utility model relates to and a kind ofly destroys and to be applied in the cement electric pole that uses on the power transmission and transformation line, particularly a kind of prestressed electric wire pole with lightning conducter for exempting from thunderbolt.
Background technology
Existing prestressed concrete electric pole cage of reinforcement longitudinal rib is a compressor wire, because of compressor wire thunder and lightning by after can cause the steel wire stress loss to make electric pole impaired, so prestressed concrete electric pole is forbidden the muscle by the electric pole master---compressor wire is made the lead-in wire of conduction thunder and lightning.If but prestressed electric wire pole is not provided with the lightning protection earthing line, runs into thunderbolt, will conduct thunder and lightning because of circuit, power equipment is damaged, cause outage even cause personal injury accidents.If oil field supply line damages oil well is scrapped, be resulted in greater loss.Usually take along electric pole peripheral hardware lead-in wire on the existing engineering or do the method for lead-in wire by cat ladder, solve this problem, but the not only corrosion and lose but also not attractive in appearance easily of peripheral hardware lead-in wire, the peripheral hardware cat ladder increases cost again, also report the loss easily, this puzzlement power department difficult problem for many years fails to solve all the time.
Summary of the invention
Task of the present utility model is to overcome the defective that existing external lightning-arrest lead-in wire electric pole exists, design a kind of prestressed electric wire pole with lightning conducter, this built-in lightning conducter prestressed electric wire pole, avoided because of thunder and lightning causes damage to electric power facility damage and relevant device facility, have both artistic and practical, not corrosion is lost, cost of manufacture is low, advantage such as easy for installation.
The utility model adopts following technical scheme for achieving the above object: a kind of prestressed electric wire pole with lightning conducter, comprise the body of rod, lightning conducter and be fixedly arranged on the lightning rod arrester on body of rod top, it is characterized in that described lightning conducter places between the interior prestressing force master muscle of electric pole, the top of lightning conducter is connected with the lightning rod arrester, and the butt of lightning conducter is connected with down conductor.
When the described body of rod is the segmentation electric pole, connect the external metallic interconnects in end at two of the segmentation electric pole, this junction plate is connected and fixed by preformed hole and connecting bolt and lightning conducter.
Be provided with the upright circle of skeleton frame in the electric pole, be used for fixing combining to steel wire in the electric pole, this upright circle is connected with lightning conducter and is closed in the electric pole wall.
For avoiding prestressing force master muscle and lightning conducter distance too near, cause main muscle conduction thunder and lightning, leave the gap of 10～20mm between lightning conducter and the prestressing force master muscle.
The built-in lightning protection earthing lead-in wire electric pole that the utility model is designed, by with being connected of arrester and down lead, make the electric pole application circuit reach lightning-arrest preferably effect, avoid causing damage to electric power facility damage and relevant device facility because of thunder and lightning, overcome prestressed electric wire pole and made the drawback of lightning-arrest lead-in wire with external lightning-arrest lead-in wire or peripheral hardware cat ladder, have attractive and durable, not corrosion is lost, cost of manufacture is low, advantage such as easy for installation, non-maintaining.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the arrester structural representation.
Among the figure: the upright circle of 1 body of rod, 2 arresters, 3 arrester holes, 4 lightning conducters, 5 metallic interconnects, 6,7 down lead connecting holes.
The specific embodiment
Referring to accompanying drawing, between the prestressing force master muscle in the electric pole body of rod 1, an indented bars is set makees lightning conducter 4, the top of lightning conducter 4 is connected with arrester 2 by arrester hole 3 and bolt, and the butt of lightning conducter 4 is connected with down conductor by down lead connecting hole 7 and bolt.Before electric pole was shaped, this lightning-arrest lead-in wire welded together with the upright circle 6 of the skeleton frame in the electric pole, and during electric pole was shaped, lightning conducter 4 also was closed in the electric pole wall simultaneously.For fear of prestressing force master muscle and lightning conducter hypotelorism, cause main muscle conduction thunder and lightning, should leave the gap of 10～20mm between lightning conducter and the prestressing force master muscle.
For whole electric pole, at the end slightly of lightning conducter, default two attaching nuts, it is connected with arrester 2, butt at lightning-arrest lead-in wire presets nut, and it can be connected with down conductor, each nut should with preset the upright circle of lightning conducter 4 and electric pole skeleton frame 6 firm welding.Lightning rod arrester 2 general employing length are for the galvanizing round steel of 1-2mm or the top is flattened and the hot galvanized steel pipe of solder up is made, and are connected firmly with two preset nuts on bolt and the lightning-arrest lead-in wire of masthead.Down conductor should satisfy the requirement of mechanical strength, corrosion-resistant and heat stability, and down lead must be connected firmly with bolt and nut on the lead-in wire.
For the segmentation electric pole, the attaching nut is preset at the steel plate ring place that is used to connect electric pole in epimere electric pole bottom, holds the steel plate ring place that is used to connect electric pole slightly at the hypomere electric pole, also presets nut, each nut must with lightning conducter 4 and the upright circle of electric pole skeleton frame 6 firm welding; Connect with metallic interconnect 5 between the segmentation electric pole, this junction plate 5 can adopt galvanized sheet.During the electric pole assembling, the lightning conducter 4 of two sections electric poles should be on same straight line; On galvanized sheet, preset attaching nut's spacing by two sections electric poles in advance and get preformed hole, the lightning conducter 4 of two sections electric poles is connected firmly with bolt by this galvanized sheet and preset nut, the lightning protection earthing lead-in wire of two sections electric poles is connected.Being connected of arrester 2 and down lead is identical with whole electric pole connected mode.
