Description
Technical field
The invention belongs to power safety technique fields, and in particular to a kind of middle-placed switch cabinet high-voltgae pothead tears anticreep when taking operation open
Ground line conduction clamp from ground protection.
Background technique
Middle-placed switch cabinet all takes high-tension cable as outlet method, when the current transformer in outlet switch cabinet carries out high pressure examination
When testing, need for current transformer and cable terminal to be detached from.As one of the safety measure of switchgear maintenance, switchgear interior lines
Road earthing switch blade closes.After busbar disengages in cable terminal and cabinet, cable just loses ground protection.As supplement
Safety measure, service personnel need to carry additionally ground line before disconnecting end on end.
Outlet cable head is located at the rear lower of switchgear, and space is narrow in cabinet, fails to be arranged between end and switchgear
Transition copper bars hang for ground line and are used.Cable terminal only has copper lug for the position of installing ground line, and copper lug has confession
It overlapped plate position and is formed for the round bar position of crimping, and crimps position and coated by pyrocondensation or shrinkage insulating part, electricity
The conductive contact surfaces that cable terminal sky stays are less.When copper lug is in overlap joint state, the collet being commonly grounded cannot be easily
It is installed on copper lug.Service personnel is when tearing open, as soon as every disconnection phase end, loads onto ground line on cable nose at once
Collet.Therefore tear open take during, cable short time be detached from grounding point, there are electric shock risks.
Ground line is divided into Special grounding wire and personal two kinds of safety wire.There are two types of the collets commonly connected wires: hook and duck
Nozzle type.The former is suitable for circular cross-section conductor, such as flexible circuit conductor, pipe mother；The latter is suitable for rectangular section conductor.Personal safety wire
Using jaw type chuck.Practice have shown that influencing tearing open for cable termination when these collets are attached on cable termination and taking, and install
Effect is bad.
Existing market has had already appeared cable termination ground protection pincers.The plier of this protection pincers has the saw of circular arc arrangement
Tooth form and linear jaw clamp round bar part and the pan section of the copper lug of cable termination by lever principle simultaneously,
The connection at round bar position or copper sheet face can individually be clamped.As previously mentioned, the round bar position of copper lug is often encased by insulating part, because
This this pliers can only be clipped in the connection in copper sheet face, after unloading overlap joint bolt, it is also necessary to remove pliers and just be able to achieve nose
With the separation of busbar, cable terminal is grounded again after separation.To prevent from sending a telegram here suddenly, this pliers has insulation handle.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of conductive chucks of cable termination ground protection line, realize
The temporary grounding of cable termination after conductive chuck installing, does not influence the dismounting of outlet cable terminal, and reduces electricity in middle-placed switch cabinet
Cable tears the number taken and assemble and disassemble ground line in work, the personal safety of effective guarantee service personnel open.
