Detailed description of the invention
Understandable, below in conjunction with the accompanying drawings to this practicality for enabling the purpose of this utility model, feature and advantage to become apparent from Novel detailed description of the invention is described in detail.Elaborate a lot of detail in the following description so that fully understanding This utility model.But this utility model can be implemented to be much different from alternate manner described here, art technology Personnel can do similar improvement in the case of this utility model intension, and therefore this utility model is not by following public The restriction being embodied as.
Upper and lower, right, top described in the utility model, bottom, inside and outside, it is according to lightning arrester live-line test aid For position in this accompanying drawing, the most therefore limit scope of the present utility model.
Refer to Fig. 1.Lightning arrester live-line test aid includes wire connecting portion 10, bindiny mechanism 20, insulating bar 30, transmission Mechanism 40 and handle 50.
Specifically, wire connecting portion 10 is for contacting the test point of counter of lightning arrester downlead.Wire connecting portion 10 includes the first pincers Mouth the 11, second jaw 12 and fixed frame 13.Wherein first jaw the 11, second jaw 12 is made by conductive material such as copper. Forming the cavity that can install two jaws in fixed frame 13, the first jaw 11 is fixedly mounted on the upper side wall of cavity.Second pincers Mouth 12 is movable jaw, and it is arranged in the lower wall of cavity by the elastic component such as spring or shell fragment, with the first mutual shape of jaw Become clamp structure, keep closing under the elastic force effect that elastic component provides.Two jaws stretch out in cavity, clamping spark gap counting Device downlead.
Bindiny mechanism 20 connects wire connecting portion 10 and insulating bar 30 respectively.In the present embodiment, bindiny mechanism 20 is the most permissible It is the Universal pipe of metal material, can arbitrarily change shape and there is shape self-retaining effect.Arrange bindiny mechanism 20 can realize connecing The angular adjustment in line portion 10, adapts to different operating environment.
Insulating bar 30 is round tube shape structure, is made up of insulant such as epoxy resin, or outside is by insulation material layer bag Cover.Bindiny mechanism 20 is installed in end, upper end, and lower end afterbody is provided with handle 50.
Handle 50 is articulated with on insulating bar 30 body of rod, stretches out from the body of rod.Handle 50 has insulation function equally, can Be use insulant such as epoxy resin make, it is also possible to be outer surface be coated with one layer of insulant.Handle 50 is curved, Pin joint is in the middle part of handle 50.The upper end of handle 50 connects drive mechanism, and drive mechanism 40 other end connects the of wire connecting portion 10 Two jaws 12.Squeeze grip 50 lower end, upper end is mobile outward pulls drive mechanism 40, under the pulling of drive mechanism 40, second Elastic component compression between jaw 12 and fixed frame 13 medial wall, the second jaw 12 moves down disengaging the first jaw 11, now wire connecting portion 10 is open configuration;After unclamping handle 50, under elastic force effect, the second jaw 12 resets, and pull handle 50 resets simultaneously.Now Wire connecting portion 10 is closure state.
In the present embodiment, drive mechanism 40 is specially steel wire.Insulating bar 30 inner hollow, and arrange along steel wire bearing of trend There is fixed pulley (not shown).Fixed pulley can be fixed on insulating bar 30 medial wall, and steel wire, from the beginning of handle, sequentially passes through hollow Insulating bar, attachment structure, fixed frame connects the second jaw 12, play gearing.
Additionally, drive mechanism can also be foil, insulating cord, or the driver being made up of multi-joint support Structure.It is outside that drive mechanism 40 can also be arranged on insulating bar 30.
Lightning arrester live-line test aid and test instrunment with the use of, during use, by the test of test instrunment Lead-in wire is connected with wire connecting portion 10, grips insulating bar 30 lower end, and tension handle 50 controls the open-shaped state of wire connecting portion 10, and clamping is lightning-arrest Device enumerator downlead test point.The test lead other end is guided to the test instrunment of flooring-safe position and is carried out wiring test, protects Card test safety.
The lightning arrester live-line test aid that the utility model proposes, utilize insulating bar 30 length increase safety away from From, prevent because of apart from too short and get an electric shock;Operating handle 40 can control wire connecting portion 10 and clamp counter of lightning arrester downlead, completes Wiring purpose, simple to operate, easy to use.
In the present embodiment, first jaw the 11, second jaw 12 is tip, to facilitate wiring.The clamping that two jaws are relative Face is zigzag.On the one hand can utilize irregular clamping face friction counter of lightning arrester downlead, remove downlead surface Scale crust and oxide layer, strengthen electrical connection;On the other hand can increase clamping dynamics, prevent from coming off.
Further, first jaw the 11, second jaw 12 lateral surface is all coated with insulation material layer, only exposes inside jaw As conducting surface.It is arranged such, causes the short circuit of test equipment in order to prevent jaw after accessing p-wire from holding contiguously.Separately In one embodiment, bindiny mechanism 20 can be bolt.Bottom fixed frame 13 and insulating bar 30 top is equipped with the hinge being mutually matched Ear, bolt inserts in hinge ear, makes wire connecting portion 10 be articulated with insulating bar 30 top, can realize angular adjustment equally.It is appreciated that and keeps away Thunder device live testing aid also can save bindiny mechanism 20, and wire connecting portion 10 is directly fixed in insulating bar 30 end.
It is also to be understood that without installing elastic component 14 in wire connecting portion 10.Now drive mechanism 40 is specially a foil, Insulating bar 30 is internal is provided with track (not shown), and foil moves along track, and handle 50 controls foil and pulls or jack-up Second jaw 12, makes the second jaw 12 move up and down to realize opening and Guan Bi of wire connecting portion 10.
See Fig. 1.In this embodiment, bottom the second jaw 12, drive mechanism 40 both sides be respectively connected with elastic component, cavity is right Sidewall is provided with track (not shown), the second jaw 12 end and this Orbit Matching, makes the second jaw 12 can glide along track Dynamic, and entirety keeps level when sliding.See Fig. 2~3.In other embodiments, only bottom the second jaw 12, driver Structure 40 side is provided with elastic component 14, and the second jaw 12 end is hinged with cavity right side wall, and the second jaw 12 is with pin joint as the center of circle Rotate upwardly and downwardly the opening and closing realizing wire connecting portion 10.
It should be noted that the second jaw 12 end is non-essential with the connection of cavity right side wall.In some embodiment In, the second jaw 12 can only rely on elastic component 14 and support, it is not necessary to arrange guide rail or pin joint on cavity right side wall.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
