Description
Technical field
The present invention relates to station technical fields, and in particular to a kind of small for overhauling the maintenance power supply that power supply picks up
Line card.
Background technique
Currently, overhauled in substation, experiment work when need to pick up maintenance power supply, use power supply disks or power supply box
Deng power supply box and power supply disks are mainly made of two insulated copper cables, and cable terminations, which peel off, 2-3 centimetres of bare copper wire, are used
When directly by bare copper wire be inserted into maintenance power supply below air switch at be used to pick up power supply.
Situation is complicated in site examining and repairing power supply box, has plenty of air switch, has plenty of binding post, and there are also socket etc., maintenance
Air switch position is lower in power supply box, and the cable terminations exposed part of power supply disks is different in size, in use, need to ceaselessly adjust
It is whole, it is all folded for insertion into and is spaced apart lower part, outside forbids exposing core, otherwise be easy to cause electric shock and short circuit, therefore connect every time
It is rather time-consuming and laborious when taking power supply.
Summary of the invention
The present invention is to solve site examining and repairing power supply to pick up time-consuming and laborious technical problem, provides a kind of reply maintenance power box
The general small line card of maintenance power supply of interior various complex situations.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows: a kind of small line card of maintenance power supply, including line
Card division and hard copper pipe sleeve two parts；The line card portion includes insulating sheath, be fixedly connected on the insulating sheath there are two close
In symmetrical first conducting rod in insulating sheath center, first conducting rod includes the first crossbar being mutually connected vertically and
One vertical bar, one end of first vertical bar and one end of first crossbar are affixed, and the other end is fixedly connected on insulating sheath, and two
The first crossbar is located at two the first vertical bars and is formed by the outside of section；In being provided in the first crossbar and the first vertical bar
Threaded hole has simultaneously screwed lock-screw；Two first crossbars are connected with the second conducting rod, institute by lock-screw respectively
Stating the second conducting rod includes the second crossbar being mutually connected vertically and the second vertical bar, and strip-shaped hole is provided in the second crossbar, the
Two cross bars and first crossbar are oppositely arranged and are located at the lower section of first crossbar, and pass through strip-shaped hole and internal screw thread by lock-screw
Realize connection in hole；The lock-screw includes stretching to the conductive threaded body of threaded hole and being connected to holding for threaded body end
Portion is held, and grip part is insulator.
In use, the insulating sheath in line card portion is set on the oversheath of cable, hard copper pipe sleeve is set in the soft of cable
It is disposably fastened on copper core and with hand vice etc.；Hard copper pipe sleeve and line card portion opposite can move up and down, and two of line card portion
Second conducting rod opposite can move left and right, carry out the adjustment of line card portion openings of sizes, be suitable for wiring of different specifications and sizes
Column.
When encountering site examining and repairing power supply is binding post, unscrew lock-screw, by mobile second conducting rod, adjusts second
Lock-screw is tightened after line card portion openings of sizes is adjusted to consistent with binding post in the relative position of conducting rod and the first conducting rod,
Then the opening in line card portion is inserted into binding post；Then the lock-screw screwed on the first vertical bar is screwed again, make line card portion with
Hard copper pipe sleeve clamps, that is, can be used.The grip part of lock-screw is insulator, and the lower part in line card portion has also installed insulation shield additional
Set, ensure that the safety for picking up power supply.
In the case that the scene of encountering is socket and air switch, the lock-screw on the first vertical bar need to only be unscrewed, it will
Line card portion is drawn onto the oversheath for the cable for being located at hard copper pipe sleeve lowest part, hard copper pipe sleeve is used only, because of hard
Copper pipe set is harder, and insertion is spaced apart and socket is all more convenient, designs just suitable insertion depth, not exposed electro-mechanical part
Point, electrical contact is also the most reliable.
Compared with prior art the invention has the following advantages:
The present invention overhauls the small line card of power supply and is suitable for air switch, and the field conditions such as binding post and socket make scene pick up maintenance
Power supply time-varying it is more convenient, safety with it is convenient.The grip part of lock-screw is insulator, and the lower part in line card portion has also installed additional absolutely
Edge sheath ensure that the safety for picking up power supply.
