Abstract
The invention belongs to a live line work tool of a medium voltage transmission line, in particular to a lead clamp for a medium voltage live circuit which is used for leading out wiring from an overhead conductor when electricity is temporarily used. The lead lamp comprises a hook-shaped conductive seat, wherein the outside of the conductive seat is provided with a connecting terminal for connecting an external lead wire; the inside of the hook part of the conductive seat is provided with an elastic conductive clamp for clamping an overhead bare conductor; the lower end of the conductive seat is provided with a section of screw for connecting an insulating operating lever; the elastic conductive clamp comprises a pair of wafers arranged in a splayed shape; the lower ends of the two wafers are connected with the lower part of the conductive seat, while the upper ends are arranged in two empty slots of the upper part of the conductive seat respectively; spring strips are arranged between the outside of the two wafers and the conductive seat; and the elasticity of the spring strips makes the two wafers be close to each other. The lead clamp effectively solves the problems that electricity is hard to cut off or a live line work vehicle cannot be in place in lapping operation, is convenient for earth potential live line work lapping on the overhead bare conductor, and has high safety.
Description
Technical field
The tools for live working of pressure transmission line in the invention belongs to, specifically be a kind of when temporary electricity, be used for from aerial condutor draw wiring pressure zone electric line cable guide.
Background technology
Traditionally, middle pressure connects electric employed T binding clip with electric unit temporarily and must be contacted (have a power failure or equipotential live line working) by the workmen with aerial condutor and just can install, and not only influences circuit and normally moves, and its fail safe is also relatively poor.
Summary of the invention
Technical problem to be solved by this invention is, a kind of lead-in wire operation, simple to operate, middle pressure zone electric line cable guide that fail safe is good of can centering pressure zone electric line overlapping is provided.
Pressure zone electric line cable guide includes the conductive seat of a hook-shaped in of the present invention, be used for connecting the binding post of outside lead in the conductive seat arranged outside, the hook of conductive seat part is inboard to be provided with and to be used for the elastic conduction folder of the built on stilts plain conductor of clamping, and the conductive seat lower end is provided with one section and is used for the screw rod that is connected with insulating bar; Described elastic conduction folder comprises the contact that a pair of being " splayed " is provided with, the lower end of two contacts is connected with the conductive seat bottom, the upper end of two contacts is placed in respectively in two dead slots on conductive seat top, between the two contacts outside and the conductive seat spring leaf is installed, the elastic force of spring leaf makes two contacts close mutually.
The upper end of two contacts also is flexible coupling to conduct electricity with the conductive seat matrix by conduction respectively and is connected.
The present invention can operate charged overlap joint operation by insulating bar, realized that installation personnel does not contact (earth potential) and installs with aerial condutor, efficiently solve the problem that power failure difficulty or live line working car can't put in place in the overlap joint operation, made things convenient for and on built on stilts plain conductor, carried out earth potential live operation overlap joint and safe.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment
As shown in the figure, pressure zone electric line cable guide includes the conductive seat 1 of a hook-shaped in being somebody's turn to do, be used for connecting the binding post 2 of outside lead 5 in the conductive seat arranged outside, the hook of conductive seat part is inboard to be provided with and to be used for the elastic conduction folder 3 of the built on stilts plain conductor of clamping, and the conductive seat lower end is provided with one section and is used for the screw rod 4 that is connected with insulating bar.Elastic conduction folder 3 comprises the contact 6 that a pair of being " splayed " is provided with, the lower end of two contacts is connected with the conductive seat bottom, the upper end of two contacts is placed in respectively in two dead slots 7 on conductive seat top, between the two contacts outside and the conductive seat spring leaf 8 is installed, the spring leaf elastic force makes two contacts close mutually.The upper end of two contacts also is flexible coupling by conduction respectively and 9 conducts electricity with the conductive seat matrix and to be connected, the reliability that connects with further assurance conduction.
In the operating process, the operator uses the insulating bar that is connected with cable guide of the present invention that cable guide is articulated on the built on stilts plain conductor, screws off action bars then and can finish the overlap joint operation.Outside lead 5 is connected with conductive seat 1 by binding post 2 before operation.
