Abstract
The present utility model provides a link bar working head which relates to the electric power construction technology field. The working head comprises a first operation arm (1), a second operation arm (2), a third operation arm (3) and a transition end connected with an insulation rod of the link bar. By adopting the link bar working head, falling of a fuse tube, ring tripping and unhooking of a vacuum switch can be prevented during the practical operation, and operation can be successfully completed at once.
Description
Technical field
The utility model relates to the power construction technical field, relates in particular to a kind of link rod working head.
Background technology
Link rod claims again brake pull-rod, insulating rod, insulated tension pole.Its is for closed or pull open high voltage isolator, the mounting or dismounting Portable ground wire, and use when measuring and testing.The 10kV link rod claims again the 10kV insulating bar, consisted of by working head, insulating bar and lever three parts, and be the insulating tool that charging equipment is operated for the short time.As closed or pull open the aspects such as high voltage isolator, fuse switch, mounting or dismounting Portable ground wire.
When adopting traditional 10KV link rod to falling type switch, vacuum switch operation, because the restraint of labour personnel's such as weather effect and the order wire that sets up on every side, dense branch or building operating space, often cause the falling of cartridge fuse, vacuum switch decylization, unhook phenomenon, not only wasted the operating time, damage electric equipment, and strengthened the economic cost of distribution network line operation maintenance.
The traditional 10kV link rod longitudinal axis is long, and transverse axis is short and smooth and be to cause the key that can not operate smoothly without blocking mechanism, and the bad weathers such as strong wind, thunderstorm are the main causes that causes fault multiple, and switch is operable to power very large impact.
Therefore, instantly need a urgent technical problem that solves to be exactly: how can propose a kind of effective measures, to solve problems of the prior art.
The utility model content
Technical problem to be solved in the utility model provides a kind of link rod working head, can evade the falling of cartridge fuse, vacuum switch decylization, unhook phenomenon in practical operation, thereby realize disposable smooth complete operation.
In order to solve the problems of the technologies described above, the utility model provides a kind of link rod working head, comprises the first motion arm (1), the second motion arm (2), the 3rd motion arm (3) and the transitioning end that is connected with the insulating bar of link rod.
Further, described the second motion arm (2) is provided with anti-skidding annular knurl and anti-drop head.
Further, described the 3rd motion arm (3) is provided with anti-drop head.
Further, the mode that employing runs through and the riveter nail welds again between the each several part of described link rod working head.
Further, described link rod also comprises transitioning end, adopts threaded rod to be connected between described excessive end and the insulating bar.
To sum up, the link rod working head that the utility model provides can be evaded the falling of cartridge fuse, vacuum switch decylization, unhook phenomenon, thereby realize disposable smooth complete operation in practical operation.
Description of drawings
Fig. 1 is the structure schematic diagram of the utility model link rod working head.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, provide a kind of structural representation of link rod working head, specifically comprise the first motion arm (1), the second motion arm (2), the 3rd motion arm (3) and the transitioning end that is connected with the insulating bar of link rod.
Wherein, described the second motion arm (2) is provided with anti-skidding annular knurl and anti-drop head 1.Described the 3rd motion arm (3) is provided with anti-drop head 2.The mode that employing runs through and the riveter nail welds again between the each several part of described link rod working head.Described link rod also comprises transitioning end, adopts threaded rod to be connected between described excessive end and the insulating bar.
Scheme described in the utility model, according to the structure situation of present high and low voltage switch operating mechanism, and original link rod working head structure often causes operation disposablely not finish smoothly.Cixi platform commonly used in the circuit operation maintenance is joined the RW-12 type, rises HPRWG-12F type falling type switch Ningbo day; Situation during four kinds of switching manipulations such as Linhai ZW6-12 type, Zhejiang China instrument ZW43A-12D type vacuum switch is investigated.
Link rod working head described in the utility model can be used for the charging equipment of high-low pressure is carried out the insulating tool of handled easily, as is switched on or switched off high voltage isolator, dropping fuse tool etc., is widely used in practice power industry, the power department in factory mine.
More than a kind of link rod working head provided by the utility model is described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
