Abstract
The utility model relates to a connecting tool for a power transmission cable, in particular to a quick-connecting tubular cable clamp. The utility model is particularly applicable to quickly connecting a power transformer, an ice melting device and an ice melting circuit of a mobile AC (alternating current) ice melting device for a 66kV power transmission line. The quick-connecting tubular cable clamp comprises two elastic clamp handles, wherein the middle parts of the two elastic clamp handles are hinged, tong heads of the two clamp handles are respectively connected with a clamp plate, so that an effective contact area is ensured; and a locking nut and a bolt are arranged between the two clamp plates, so that the clamping force between the two clamp plates is increased, and a good contact state is ensured. Arc-shaped, elliptical or semicircular concave wire slots can be correspondingly processed in the two clamp plates, and the quick-connecting tubular cable clamp is a tubular fixture and is applicable to quickly connecting a special soft copper wire and a steel reinforced aluminum strand conductor of an overhead line. The locking nut and the bolt are respectively a shoe-shaped nut and a screw rod and can be directly screwed without a wrench, so that the quick connection is realized. The quick-connecting tubular cable clamp has the characteristics that the contact state is good, the connection is firm, and the application range is wide.
Description
Technical field
The utility model relates to a kind of power transmission line fastening means, and promptly quick connecting pipe formula wire clamp is specially adapted to the portable quick connection that exchanges power transformer, deicing device and DC ice-melting in the deicing device of 66kV transmission line.
Background technology
In the prior art, behind the powerline ice-covering, possibly cause device damage such as conductor cord disconnection, shaft tower topple; In icing comes off process; Possibly cause that circuit waves repeatedly short circuit tripping operation, the operation of serious threat substation safety, influence is to the reliable electricity consumption of user's security.The Northeast's daily temperature changes greatly, and because of there's a sudden fall in temperature, the icing time is long behind the wire icing, removes very difficulty.Present portable deicing device adopts the DC ice melting scheme more, needs high current power electronic rectifier equipment, complex equipments, and cost is high; Exchange deicing device and adopt stationary structure more, equipment disposition point is many, and cost is high.In conjunction with on-the-spot actual, the 66kV transformer station of operation does not have the ice-melt facility at present, receives on-the-spot restriction to build relatively difficulty of special-purpose ice-melt facility, and this patent has proposed concrete settling mode to this.Power transmission line connected to adopt usually between wire clamp and wire clamp and was connected with bolt in the past; Its shortcoming is that the screw hole between wire clamp and wire clamp is very accurate apart from requiring; Be connected with former wire clamp like need, because wire clamp is charged in operation, accurate measured hole distance; Need on-the-spot have a power failure back measured hole distance, boring when causing the ice-melt wire clamp to be connected with former wire clamp; Wasted a large amount of human and material resources and time, and the ice-melt wire clamp that has formed the fixing hole distance can't be connected again with the wire clamp of other pitch-row, need change again the ice-melt wire clamp and with ice-melt conductor compression jointing, boring.
The utility model content
The purpose of the utility model be provide to above-mentioned deficiency a kind of contact well, be connected firmly, quick connecting pipe formula wire clamp applied widely.
The technical solution of the utility model is: quick connecting pipe formula wire clamp comprises middle two hinged resilient holding arm, and two clamp holder binding clips are connected with clamping plate respectively, have guaranteed effective contact area; Lock nut and bolt are arranged between two clamping plate, can increase the clamping force between the clamping plate, guarantee that contact is good.
Can correspondence be processed with arc, ellipse garden shape or semicircle concave groove in two clamping plate, be the tubular type anchor clamps, be applicable to that special-purpose annealed copper wire is connected with the quick of overhead transmission line steel reinforced aluminium conductor.
Lock nut and bolt are butterfly nut and screw rod, need not prepare spanner, directly twist to connect, and realize connecting fast.
The utility model has the advantages that: be mainly used in 1, that the interim of device clamp and device clamp is connected fast in the electric power system.2, device clamp need not boring, has solved pitch-row problem inconsistent or that do not hole between wire clamp, and the scope of application is very extensive, and flexibility is strong.3, under the double action of clamp holder spring and ingot bolt, make between clamping plate pressure enough big, guaranteed that the device clamp contact is good.4, this wire clamp is as a whole, need not any Work tool and can accomplish fastening to device clamp, and conventional bolt connects relatively, has avoided carrying the trouble of Work tool, multiple parts and has been prone to lose, be prone to the equivalent risk that comes off.5, thickness and the length of conduction clamping plate have guaranteed the contact area with lead and device clamp, thereby have guaranteed the water conservancy diversion amount.
To combine accompanying drawing that the execution mode of the utility model is described in further detail below.
Description of drawings
Fig. 1 is the utility model working state structure sketch.
Fig. 2 is Fig. 1 plan structure sketch.
Embodiment
Referring to Fig. 1,2; Two resilient holding arm 1,2 of quick connecting pipe formula wire clamp hinged in the middle of comprising (centre have be wound with spring 6 on connecting axle 5, the axle); Two clamp holder binding clips are connected with metal splint 3,4, two clamping plate 3 respectively, locking butterfly nut 7 and screw rod are arranged between 4.Each clamping plate 3,4 inner face be to should there being semicircle concave groove 12, clamping plate 3, pressed from both sides the lead 13 of connection between 4, and connected device clamp 8 is below clamping plate 4.This tubular type quick wire clamp is mainly used in that the interim of device clamp and lead is connected fast in the electric power system.The wire clamp of said structure is specially adapted to the portable quick connection that exchanges power transformer, deicing device and DC ice-melting in the deicing device of 66kV transmission line.
Claims (2)
