Abstract
The utility model discloses a power cable emergency changeover plug. A main insulating material is wrapped outside a conductive body, the power cable emergency changeover plug is characterized in that one end of the conductive body is provided with a threaded hole, and the other end of the conductive body is provided with a needle type hole; an outer layer of the insulating material at one end of the threaded hole of the conductive body is tapered; and the outermost layer of one end of the needle type hole of the conductive body is provided with a shielding layer. The power cable emergency changeover plug solves the problems of operability and economical efficiency of fast connection between a power cable elbow-shaped plug and a bypass operation cable under the working condition that a bypass of a power distribution network operates without power failure, is convenient to build a bypass system quickly on the spot, and brings high efficiency for the bypass of the power distribution network to operate without power failure.
Description
Technical field
The utility model relates to a kind of cable changeover plug, relates in particular to the emergent changeover plug of a kind of power cable.
Background technology
In the process of power distribution network ring main unit bypass uninterrupted operation, often original power cable and bypass operation cable temporarily need be linked together fast, after the end of job, power cable returns to original connection status.Original power cable generally adopts elbow type plug, and elbow type plug kind is more not general mutually, causes to be connected to become fast a difficult problem between a set of bypass operation cable and multiple power cable.
Being connected between bypass operation cable and power cable, there are at present two kinds of modes: a kind of is that the original plug of power distribution network power cable is amputated, with one end be naked head bypass operation cable by field fabrication not plug type transition joint be connected, after completing construction, amputate again this transition joint section, again to power cable, withhold plug, this kind of operating type removed plug-in joint from and connected the protector needing, but field fabrication can not plug transition joint operation loaded down with trivial details, with duration, and labor intensive; Another kind of connected mode is the multiple bypass operation cable of preparation, its plug is applicable to respectively various power cables, according to operation field needs, the corresponding bypass operation cable of interim selection, this kind of operation form avoids that the first flow chart is loaded down with trivial details, the shortcoming of labor intensive, but because the many covers of need preparation are worth high bypass operation cable, economy is poor.
summary of the invention:
The utility model object is to provide the emergent changeover plug of a kind of power cable, this cable changeover plug can be realized quick connection the between bypass operation cable and multiple power cable, can solve the quick connectivity problem of the different elbow type plugs of power distribution network power cable and bypass operation cable, simple operation, good economy performance.
The technical scheme that realizes the utility model object is: a kind of power cable changeover plug of meeting an urgent need, in electric conductor coated outside, there is main insulation material, and it is characterized in that: one end of described electric conductor is provided with screwed hole, the other end of electric conductor is provided with pin type hole; Insulating material skin in screwed hole one end of electric conductor is provided with tapering; In one end, pin type hole of electric conductor, outermost layer is provided with screen.
Technique scheme has following prioritization scheme:
Described electric conductor, adopts copper electric conductor, or silver electric conductor, or aluminium matter electric conductor.Also can adopt the electric conductors such as stainless steel.
At described screen, be outside equipped with self-locking mechanism.
Described electric conductor screwed hole, adopts and directly in electric conductor end, bores the form formation that processes screwed hole.Or,
Described electric conductor screwed hole, adopts following nested bolt structure: nested double-screw bolt external screw thread is connected with electric conductor with unified screw thread, and the internal thread form of electric conductor is respectively arranged with various ways.
The beneficial effects of the utility model are, solve the quick operability being connected and economy problems between power cable elbow type plug and bypass operation cable under power distribution network bypass uninterrupted operation operating mode, bypath system is built rapidly at the scene of being convenient to, for the bypass uninterrupted operation of power distribution network brings high efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Embodiment 1, and the power cable changeover plug of meeting an urgent need, with reference to Fig. 1: electric conductor 1 one end is with nested double-screw bolt 2, one end is with pin type hole 6, and electric conductor 1 is outer covers main insulating layer 3, and main insulating layer 3 one end are provided with tapering, in pin type hole, 6 end outermost layers are provided with screen 4, at the outer self-locking mechanism 5 that arranges of screen 4.Nested double-screw bolt 2 external screw threads are M20, two kinds of specification M10 of internal thread house and M8.
Power distribution network power cable elbow type plug is connected with the nested double-screw bolt 2 on changeover plug by bolt, elbow type plug inwall coordinates closely with the main insulating layer 3 of tapering with this place, the pin type conductor of bypass operation cable plug inserts in the pin type hole 6 of changeover plug, screen 4 contacts conducting with bypass operation cable plug screen, then by self-locking mechanism 5, the locking of bypass operation cable plug and changeover plug is connected, by electric conductor 1, realizes being communicated with to putting of power distribution network power cable elbow type plug and bypass operation cable plug.
