The utility model discloses a compact line jumper wire expander, comprising a screw type bayonet wire clamp, more than one insulating operating rod, and a locking device for fixing the compact line jumper wire expander; wherein a movable block of the screw type bayonet wire clamp is in movable detachable connection with an end portion of one insulating operating rod, movement of the movable block is controlled by the insulating operating rod, more than two insulating rods are connected together by adopting a connecting device, and the locking device is detachably and movably sleeved on one insulating rod. The compact line jumper wire expander of the utility model has the advantages of simple structure and convenient use and maintenance. After the complete set of the compact line jumper wire expander is installed, a jumper wire can be effectively expanded and fixed, thereby ensuring an enough safe distance between operating personnel and the live-line jumper wire, and preventing the operating personnel from electric shock.
Description
Technical field
The utility model relates to a kind of live working tools, and particularly a kind of compact strain rod tower wire jumper struts and effectively fixing compact line wire jumper expander.
Background technology
Progressively development along with power construction, in order to save the transmission line construction cost of investment, much more present 220kV common-tower double-return erects power transmission lines to adopt the compact lines design, the design of its steel tower is most of is the design of trourelle window, the arrangement mode of wire is vertical arrangement, due to its alternate and relatively the distance less than normal, operating type can't satisfy minimum safe distance and the combinational gap of stipulating in standard and rules routinely.Make live line working to carry out.Take 220SJ11 drum type tower as example, 6.5 meters of its phase spacings, the upper strata drainage thread is 2.2 meters (through in-site measurements) apart from lower floor's cross-arm minimum distance." State Grid Corporation of China's electric power safety working regulation (power circuit part) " relevant Generally Recognized as safe technical measures regulation that guarantees live line working: the 8.2.1(summary) when carrying out the earth potential live operation, the person must not be less than the regulation of table 8-1 with the safe distance of electrified body.Stipulate in table 8-1, when carrying out the earth potential live operation, the person must not be less than 1.8 (1.6) meters with electrified body minimum safe distance 220kV.Hence one can see that, leave operating personnel's maximum operating space for and only have 2.2-1.6=0.6 rice, suppose operating personnel's 1.8 meters of heights, ratio in 4:6, it also has 0.72 meter above the waist, add operating personnel's normal scope of activities of health when operating, its 0.6 meter＜0.72 meter can't be carried out operation at all.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provides a kind of applicable to above-mentioned circuit, widely applicable, safe and reliable compact line wire jumper expander.
A kind of compact line wire jumper expander, include spiral bayonet socket wire clamp, insulating bar more than one, the locking device that compact line wire jumper expander is fixing, the movable block of spiral bayonet socket wire clamp is movable dismountable motion that is connected and is controlled movable block by insulating bar with an end of thoroughly doing away with the edge action bars, adopt jockey to interconnect between insulating bar more than two, the dismountable movable set of described locking device is on an insulating bar.
The compact line wire jumper expander of this structure, at first select whether to select the radical of insulating bar according to the electric pressure of circuit, guaranteeing under the enough safe distance situations of human body and electrified body maintenance, hand-held insulating bar is hooked on spiral bayonet socket wire clamp on wire jumper, then rotating insulated action bars, be locked on wire jumper spiral bayonet socket wire clamp.To the direction away from the operating personnel, another people utilizes the locking device on expander, and insulating bar is fixed on the steel tower cross-arm securely, installs with the insulating bar support, and wire jumper is effectively strutted.
Connection between described insulating bar more than two or adopt between any two screw thread to connect, or adopt that the connectors such as latch, thread bush are auxiliary to be connected.
Adopting screw thread directly to connect it can be on the insulating bar of, external screw thread to be set, and internal thread is set to realize both connections on the insulating bar of another root.
Described employing connector is connected to or at the abutting end of two insulating bars, external screw thread is set all, and the two ends of inner chamber all arrange internal thread on connector.
Described locking device be sliding sleeve on insulating bar, be to be threaded connection part realize its locking or relatively be active on insulating bar.
The locking device that adopts this structure to connect can be according to the device of the needs flexible choice locking device that uses with respect to insulating bar.
Described locking device or be the hood type locking device, or for to be made of a fixed block and movable block, movable block is connected in fixed block by screw mandrel, and movable block fixed block is relatively done in opposite directions or opposing motion.
When needs are locked, first dehiscing between movable block and fixed block snapped in cross-arm, the rotary moveable piece makes its relative fixed block motion until cross-arm is clamped.
In sum, the utility model following advantage compared to existing technology:
Compact line wire jumper expander of the present utility model has simple in structure, and working service is advantage easily.After the installation of a whole set of compact wire jumper Expending device, can effectively strut and fix wire jumper, guarantee that operating personnel and charged wire jumper keep the safe enough distance, prevent that the operating personnel from getting an electric shock.
Description of drawings
Fig. 1 is the structural representation of the compact line jumpers expander of the utility model embodiment.
Spiral bayonet socket wire clamp 2 insulating bar 3 connector 4 locking devices of label declaration 1.
Embodiment
Below in conjunction with embodiment, the utility model is described in more detail.
Embodiment 1
With reference to accompanying drawing 1, compact line wire jumper Expending device includes spiral bayonet socket wire clamp 1, epoxy resins insulation action bars 2, connector 3, locking device 4.The operation principle of compact line wire jumper Expending device is: (1) spiral bayonet socket wire clamp is fastened on the epoxy resins insulation action bars, makes spiral bayonet socket wire clamp sting tight wire jumper by rotating ring epoxy resins insulating bar.(2) the epoxy resins insulation action bars forms by two, and the centre has connector, is used for connecting the epoxy resins insulation action bars more than two, with the length of control ring epoxy resins insulating bar.Electric equipment as following in 110KV uses single epoxy resins insulation action bars safe distance more than 1.7 meters, and the 220KV electric equipment uses two epoxy resins insulation action bars docking, and safe distance reaches more than 3.5 meters.The centre of epoxy resins insulation action bars is furnished with a locking device that can move flexibly up and down, locking device utilizes locking and the movement of threaded connector realization on insulating bar, also utilize simultaneously a fixed block and movable block to consist of, movable block is connected in fixed block by screw mandrel, movable block relatively fixed block do in opposite directions or opposing motion in order to the epoxy resins insulation action bars is fixed on cross-arm securely.After the installation of a whole set of compact wire jumper Expending device, can effectively strut and fix wire jumper, guarantee that operating personnel and charged wire jumper keep the safe enough distance, prevent that the operating personnel from getting an electric shock.
