Description

The quick short-circuit device of a kind of power line DC ice-melting
Technical field
The utility model provides a kind of power line DC ice-melting quick short-circuit device especially, belongs to power circuit equipment gold utensil technical field.
Background technology
Mostly the mode that present ice-melt operation is adopted is the ice-melt of direct current short circuit; Need the staff that the short circuit cable is sling and carry out the high-altitude installation; Because big electric current of ice-melt and the requirement of conduction time are arranged; Wiring requirement to the high-altitude is more careful, and workload is big, needs to adorn, tear open being connected of Stranded cable joint and high-tension line.In order to reduce interruption duration; New rules require to reduce the ice-melt time (the ice-melt actionable total time was controlled in 4 hours) as far as possible; And it is more when adopting retractable and the fixed charge of present technological short-circuiting cable; Fatigue takes place in staff easily, and the operational environment general summer coolness is wet and slippery in addition, and operating time length and fail safe also are inversely proportional to.A large amount of ice-melt operations that the icing phenomenon of the high-voltage lines that exist in a large number winter at present causes will have a strong impact on job safety.Therefore; The exploitation of carrying out novel ice-melt design for scheme and novel ice-melt gold utensil has important practical value; Can reduce solve extensively exist carry out the spent a large amount of manpower, material resources and financial resources of line ice-melting operation; Improved the operational security under harsh weather, operation quality and efficient solve the high-altitude application of original dependence relative complex and the limited insoluble de-icing technology problem of operation means.For solving the problem of above-mentioned situation, many new technology new products have appearred.Their structure, material have nothing in common with each other, and have also reached the purpose of protection circuit to a certain extent.
Not only require metal fixture that enough intensity, impact resistance will be arranged in actual use, and require under bad weather conditions such as high height above sea level heavy icing area, can have very strong durability, the compactness of connection, the flexibility of operation, and the high efficiency of operation.Domestic in recent years each relevant unit has all carried out development to it and has improved, but its ruuning situation is also not fully up to expectations.
Summary of the invention
The technical problem that the utility model will solve has provided a kind of novel structure, material is reasonable, weight is little, be convenient to the quick short-circuit device of a kind of power line DC ice-melting of installation exercise, can overcome the deficiency of prior art.
The technical scheme of the utility model is: it comprises spliced cables, goes up fixture block and following fixture block; One end of last fixture block and following fixture block adopts hinge to be connected; At the other end of the lower plate locking nut that has been connected through the hinge, on last fixture block, offer the grooved mouth that cooperates with locking nut; On the opposite face of last fixture block and following fixture block, offer the cable bayonet socket that matches, be connected with the clamping head that is connected fast with spliced cables on the fixture block down, spliced cables is connected on the clamping head.
Between the two cable bayonet sockets that coincide, be provided with the beryllium copper intermediate plate.
On locking nut, be connected with the rotating ratchet spanner.
Be connected with the coupling mechanism force adjusting rod on the fixture block down.
The clamping head is connected with beryllium copper intermediate plate on being connected down fixture block.
On the clamping head, be provided with screw thread, be connected with the fast connector that cooperates with the clamping head in the end of spliced cables.
Compare with prior art; The utility model main part employing lightweight, the metallic aluminium that resistance is little and through-current capacity is big; Overall weight≤3kg, ratchet spanner handled easily personnel tighten anchor clamps fast, can significantly shorten operating personnel's operating time through the application of this lap joint.It is the fixture block of material that beryllium copper is adopted in the transition of transmission line and jig main body structure; Guarantee that lap joint contacts and minimum contact resistance with the lead maximum area; Coupling mechanism force adjusting rod scalable fixture block up and down prevents the excessive damage conductive line surfaces of pressure to the pressure of cable, and the beryllium copper intermediate plate can be according to the size of required ice-melt cable; Select not install all size, guarantee that the maximum contact face of cable and lap joint connects and minimum contact resistance.
The utility model also has the following advantages:
1, the press-hang type structure is adopted in the technological design of short circuit gold utensil, can dismantle quick and convenient laborsaving according to the thickness rapid adjustment of ice-melt cable under round-the-clock situation; And the stable time is long, and maintenance cost is little.Under the condition of construction that operating time length and fail safe also are inversely proportional to, reduce the work high above the ground time, increased working security.
2, short-circuiting cable changes lightweight soft copper cable into by original normal cable, guarantee through-flow, convenient lifting, and the temperature that this material has also guaranteed the ice-melt cable is within the temperature range that ice-melt requires.
3, the design of this metal fixture has taken into account the convenience design of joint under the index request that satisfies the big electric current of ice-melt short circuit; In light weight; Mechanical strength is big, and the anti-aging time is long, also can normally carry out when swing takes place overhead wire under harsh weather even guaranteed the whole erection operation.
The application of the utility model simultaneously can improve the ice-melt operating efficiency greatly, greatly reduces ice-melt operations labor intensity and operating time, can short circuit lead installation effectiveness be enhanced about more than once.For present southern area be about to carry out a large amount of ice-melt operations and facilitate, reduce expending of manpower and materials.The technological design of novel in addition ice-melt gold utensil with transform also to the utensil of other work high above the ground and operation scheme provide improved reference, can extensively improve the operating efficiency of this type of operation, obtained good economy and society benefit.
