Abstract
The utility model relates to a power transmission line connecting tool, in particular to a quick-connection plate type wire clamp which is particularly applicable to quick connection of a power transformer, an ice melting device and an ice melting line in a movable alternating current ice melting device with a 66kV power transmission line. The quick-connection plate type wire clamp comprises two elastic clamp handles with hinged middles, and jaws of the two clamp handles are respectively connected with a clamp plate, so that effective contact area is ensured. A locking nut and a bolt are arranged between the two clamp plates, so that clamping force between the clamp plates can be increased, and fine contact is ensured. At least one clamp plate is connected with the jaw of the corresponding clamp handle through a rotary shaft to form a rotatable structure, layers are parallel after being clamped, and the quick-connection plate type wire clamp is applicable to quick connection of special soft copper wires and copper bars. The locking nut and the bolt are a wing nut and a screw respectively and are directly screwed without preparing a wrench, and quick connection is realized. The quick-connection plate type wire clamp has the advantages of effectiveness in contact, firmness in connection and wide applicable range.
Description
Technical field
The utility model relates to a kind of power transmission line fastening means, i.e. rapid connection plate formula wire clamp is specially adapted to that the 66kV transmission line is portable to exchange that power transformer, deicing device and the quick of DC ice-melting are connected in the deicing device.
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, rapid connection plate formula wire clamp applied widely.
The technical solution of the utility model is: rapid connection plate 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.
Wherein be connected through rotating shaft between at least one clamping plate and the clamp holder binding clip, be turnable structure, guaranteed to be in parallel position after each interlayer clamps, be board-like anchor clamps, be applicable to quick connection of special-purpose annealed copper wire and copper bar (transformer connection plate).
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: 1, this board-like quick connecting clamp is mainly used in 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 effect of fixed hub and movable rotation-shaft, guaranteed ambulatory splint no matter under great angle (in the folder mouthful maximum travel limit), can both keep level with strap, thus guaranteed with device clamp contact and to the pressure of device clamp.4, 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.5, 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.6, 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.

Embodiment
Referring to Fig. 1,2; Two resilient holding arm 1,2 of rapid connection plate 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.Be connected through rotating shaft 9 between clamping plate 3 and clamp holder 1 binding clip.Fig. 1 middle clamp plate 3, pressed from both sides the device clamp 10,11 of connection between 4.This board-like quick wire clamp is mainly used in that the interim of device clamp and device clamp is connected fast in the electric power system.
Claims (3)
1. a rapid connection plate formula wire clamp comprises middle hinged two resilient holding arm (1,2), it is characterized in that two clamp holders (1,2) binding clip is connected with clamping plate (3,4) respectively, and two clamping plate have lock nut and bolt between (3,4).
