Description
Technical field
The utility model relates to the instrument of distribution line live working in a kind of electric power system, is specifically related to a kind of insulating bar that is used for the two ditch wire clamps of band of distribution line.
Background technology
The 10kV distribution line live working is divided into two kinds of methods---insulating gloves method and insulating bar method.The insulating gloves method is meant the operating personnel on workbench (adopting insulating ladder, insulation unipods barre and live line working overhead vehicle insulation bucket), by insulating gloves and with the suitable insulation blocking of different potentials on every side directly electrified body is carried out operation.The insulating bar method is meant that operating personnel and electro-mechanical part maintain a certain distance with insulating bar and carries out operation.
Utilize that the insulating gloves method is chargedly torn open, during joining seam, the direct contact electrification lead of operating personnel, with zero load lead-in wire overlap joint when electric lead being arranged or unloaded lead removed, because lead is a capacitive, instantaneous meeting produces electric arc, especially it is more obvious to prop up when connecing electric arc at the overlap joint long transmission line, has certain unsafe factor.If adopt the insulating bar method, fail safe can guarantee, but because personnel carry out operation to electrified body indirectly, the operation control performance is poor, and the overlap joint difficulty is big, overlap joint quality instability.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of safe, be used for the insulating bar of the two ditch wire clamps of band of distribution line reliably, easily, it can at overlap joint or be removed when lead-in wire easily produces electric arc and adopt, and realizes indirectly electrified body being carried out operation.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of insulating bar that is used for the two ditch wire clamps of band of distribution line, comprise two ditch wire clamps and the action bars that removably connects by connector, wherein,
Described pair of ditch wire clamp comprises:
One wire clip body, it is a hollow strip block, and its inner chamber is provided with screw body, and the screw mandrel bottom of this screw body passes the lower surface of wire clip body, and the lower end of this screw mandrel is provided with an oblateness and offers the cardan of threaded perforations;
One is the upper grip head of C font, the opening that the inner of its top pincers tongue is passed on the wire clip body side is connected with the nut of screw structure, the inner of its bottom pincers tongue is fixed on the side of wire clip body, and its top pincers tongue is realized and bottom pincers tongue opening and closing at the action bars of screw mandrel lower end by being rotatably connected;
One is the lower pliers head of the type of falling J of inclination, the inner of its top pincers tongue is fixed on the side of wire clip body and is positioned at the below of the bottom pincers tongue of upper grip head, offer a tapped through hole on the surface of its bottom pincers tongue, the adjusting screw(rod) that head has cap is connected in this tapped through hole;
The joint that the head connection one of described action bars and the cardan of two ditch wire clamp lower ends are complementary; Described connector is one to have the screw of handle.
The insulating bar of the two ditch wire clamps of the above-mentioned band that is used for distribution line, wherein, the length of described insulating bar is 0.6m.
The insulating bar of the two ditch wire clamps of the above-mentioned band that is used for distribution line, wherein, the surface of the cardan of described pair of ditch wire clamp is provided with pawl slot, and the joint surface of described action bars is provided with the ratchet with described pawl slot coupling.
The insulating bar of the two ditch wire clamps of the above-mentioned band that is used for distribution line, wherein, described pair of ditch wire clamp adopts high-strength aluminum alloy to make.
The insulating bar of the two ditch wire clamps of the above-mentioned band that is used for distribution line, wherein, described insulating bar adopts the expoxy glass steel to make.
Owing to adopted the technical scheme of the insulating bar of the two ditch wire clamps of the band that is used for distribution line of the present utility model, avoided when the operation of insulating gloves method, the capacitance current in an instant that lead-in wire contacts with lead can produce electric arc, avoid the operating personnel to contact two different potentials leads, the potential safety hazard of generation on the other hand.Use the insulating bar of the two ditch wire clamps of band,,,, have the distance of 0.4m at least, it is hereby ensured operating personnel's safety by being connected of insulating bar control lead-in wire and lead because the operating personnel is below circuit even produced electric arc.
