Abstract

The utility model discloses a special cable clamp for live installation of a lightning arrester at a ground potential, which comprises a cable clamp body, wherein one end of the cable clamp body is provided with a hole which is connected with the lightning arrester, the other end of the cable clamp body is provided with a groove which is used for hanging and connecting wires, a pressing block is arranged opposite to the groove, the pressing block is connected with a threaded rod, the threaded rod is fit with a screw hole on the cable clamp body, and a lifting lug is arranged outside one end of the groove and provided with a lifting hole. An operator at the ground potential lifts the cable clamp, hangs the cable clamp on a wire on which the lightning arrester is installed by using an insulating operation rod with a hook and then tightens the threaded rod by using an insulating operation rod with a socket spanner, so that the pressing block and the groove which is used for hanging and connecting wires are matched and the wire is clamped, and then the operator connects the lightning arrester and the cable clamp body. The special cable clamp is simple in structure and capable of achieving ground potential operation, so that the operator is not in direct contact with a charged body, the safety of staffs and devices is improved greatly, time for live installation of the lightning arrester is shortened to 16 minutes from the original 28 minutes, and manpower and material resources are saved.

Description

A kind of at the special-purpose wire clamp of earth potential live installation lightning arrester
Technical field:
The utility model relates to a kind of electric power facility apparatus for mounting, particularly relates to a kind of at the special-purpose wire clamp of earth potential live installation lightning arrester.
Background technology:
Chengde electrical network is located in many Leishans district, because the power grid accident that thunder and lightning causes is increasing, the power grid accident that the minimizing damage to crops caused by thunder of adopting an effective measure causes is particularly important.It is one of effective technology means of current power transmission circuit reduction tripping rate with lightning strike that leakage conductor is installed.Charged installation lightning arrester has improved power supply reliability, has avoided interruption maintenance and causes and send electric weight less.Also strengthen simultaneously maintenance scheduling property, after the employing hotline maintenance method, can keep the operational mode of system constant, guaranteed the safe operation of electrical network, reduced equipment and personal injury.Compare the equipment and the personal injury that greatly reduce fault rod climbing tower, mistakenly entering charged chamber, misoperation and cause because of formalities such as power failure repeatedly, electrical verification, hanging earthing conductors with the power failure operation.Live line working is meant the operation that high voltage electric equipment and facility are not had a power failure.The live line working method is divided into three kinds: (1) equal potential working: refer to that operating personnel and electrified body are in the operation of same current potential, equipotential electrician gets into current potential generally will use instruments such as flat ladder or rope ladder; (2) earth potential working: the operating personnel is in earth potential (standing on the shaft tower) state when referring to live line working, utilizes the operation of insulating tool indirect contact high-voltage charged body; (3) medial potential working: the operating personnel is in the operation on the current potential between electrified body current potential and the earth potential when referring to live line working.At present; China is in charged installation lightning arrester operation process, and the method for work of use all is the equal potential working method, and the equal potential working method needs the equal potential working electrician to climb rope ladder or flat ladder gets into current potential; Multiple insulation power tool need be set; And it is very loaded down with trivial details that these power tools are set, and task difficulty is big, and labour intensity is big.Through the activity duration of charged installation lightning arrester is added up, adopt the equal potential working method that the activity duration average out to 28 minutes of a lightning arrester is installed, and equal potential working require very high to electrician's physical efficiency, technical ability.Simultaneously the equal potential working method can only be confined in the part shaft tower that safe distance such as combinational gap meets the demands, and some little spacing shaft towers are owing to receive the restriction of air gap can not carry out charged installation lightning arrester to work.
The utility model content:
The utility model provides a kind of and at earth potential live the special-purpose wire clamp of lightning arrester is installed to the deficiency of prior art, and this wire clamp is rational in infrastructure; Can be implemented in earth potential live lightning arrester is installed, safety, convenient, time saving and energy saving; The utility model technical problem to be solved is to make the operating personnel use insulating tool easily wire clamp to be fixed on the lead at the earth potential place, and the technical scheme that the utility model is taked is following: the utility model comprises the wire clamp body, and an end of wire clamp body is provided with the hole that is connected with lightning arrester; The other end is provided with the groove that articulates lead; Relative with groove is a briquetting, and briquetting links to each other with screw rod, and screw rod cooperates with screw on the wire clamp body; It is characterized in that being provided with hanger in the outside of groove one end, hanger is provided with lifting hole(eyelet).
The method for using of the utility model is following:
Operating personnel's earth potential place uses the insulating bar of band hook that wire clamp is provoked and is suspended on the lead that lightning arrester is installed; The insulating bar that re-uses the band box spanner is tightened screw rod; Make briquetting and articulate the groove fit clamping wire of lead, lightning arrester is connected with the wire clamp body gets final product then.
Compared with prior art; The utlity model has simple and reasonablely, cost is low, can realize earth potential working; Make the not direct contact electrification body of operating personnel; The fail safe of personnel, equipment improves greatly, and the time of charged installation lightning arrester shortened to 16 minutes by original 28 minutes, saved manpower and materials.

Accompanying drawing 2 is the utility model left views
Embodiment:
The utility model comprises wire clamp clamp 6, and its effect is to connect lightning arrester and lead, and an end of wire clamp clamp is provided with the hole 1 that is connected with lightning arrester; The other end is provided with the groove 9 that articulates lead, to the lead 5 in collinear footpath not, can establish the grooves of different sizes; Relative with groove is a briquetting 4, and the surface of briquetting is an arc, and briquetting links to each other with screw rod 3; Screw rod cooperates with screw on the wire clamp body, also is provided with locking nut 2 on the screw rod, is provided with hanger 7 in the outside of groove one end; Hanger is provided with lifting hole(eyelet) 8, and the utility model can be realized earth potential working installation lightning arrester.
