Abstract
The utility model discloses an instrument is cut to overload protection device's screen top bar copper generating line, include the pincers body of constituteing by handle and round pin axle, the pincers body contains two arc chucks, and two arc clamping head group close and form cylindrical or prismatic structure, be provided with well flat groove at the middle part of two arc chucks, two well flat groove combination backs are on the coplanar, and be furnished with with the saw of well flat groove cooperation installation. The utility model discloses can cut the operation on protecting the stable basis of copper generating line, prevent and lead to the fact the short circuit or lead to the fact short circuit hidden danger problem because of copper generating line mode misplaces. And can improve cutting efficiency, and its simple structure, it is effectual.
Description
Technical field
This utility model belongs to aid in electric power renovation technique field and in particular to a kind of screen of protective relaying device
Top copper rod bus cutting tool.
Background technology
With the fast development of China's power system, integrated automation of transformation stations transformation accordingly steps up to carry out.However,
Old relay-set exits when carrying out relay protection transformation, needs to cut off the little bus of powered exposed operation.Traditional common side
Method be little bus is cut off in the middle of two sealers with cable clamp after, old relay-set could be exited, newly shield in place.
Shear history needs many people meticulously to coordinate, although staff is very conscientious, careful, careful, because little bus asks septal space
Little, exposed powered, little bus bar is asked, interlayer is too little, and shear history is time-consuming, laborious；Furthermore artificial processing ease produces deviation, cuts
Section very irregular it is easy to cause little busbar short-circuit；Operator also have Danger Electric shock risk；When newly screen is in place, there is touching two
The powered little bus in side and cause the danger of short circuit grounding.
Utility model content
This utility model is directed to relevant issues present in current protective relaying device transformation process, provides a kind of relay to protect
The shielding top copper bar bus cutting tool of protection unit.
The technical solution of the utility model：A kind of shielding top copper bar bus cutting tool of protective relaying device, including by handle
The caliper forming with bearing pin, described caliper contains two arc clamping heads, and two arc clamping heads combinations form cylindrical or prismatic knot
Structure；Rise as high as the banks in the middle part of two arc clamping heads is provided with, after combination of rising as high as the banks in two at grade；And be furnished with rise as high as the banks
The saw that cooperation is installed.
It is provided with enlarging at the opening risen as high as the banks in described.
Described saw for hand-held tool or be electric saw.
The beneficial effects of the utility model：This utility model can be cut on the basis of protection copper coin bus is stable
Operation, prevents and causes short circuit or cause short-circuit potential problem because copper coin bus mode misplaces.And cutting effect can be improved
Rate, its structure is simple, and effect is good.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure, label 1 be handle, 2 be bearing pin, 3 be arc clamping head, 4 be in rise as high as the banks, 5 be enlarging, 6 be saw.
Specific embodiment
Embodiment 1：The shielding top copper bar bus cutting tool of protective relaying device shown in Figure 1, caliper is by handle 1 and bearing pin
2 compositions.Caliper contains two arc clamping heads 3, and two arc clamping head 3 combination forms cylindrical or prismatic structures；Press from both sides in two arcs
The middle part of head rises as high as the banks 4 in being provided with, after 4 combinations of rising as high as the banks in two at grade；And be furnished with rise as high as the banks cooperation install
Saw 6.
In rise as high as the banks 3 opening at be provided with enlarging 4.
The saw 6 being adopted is hand-held tool or is electric saw.
