Description
Technical field
The present invention relates to a kind of loop resistance p-wire jointing clamps.
Background technology
In the test job of 500kV substations contact surface loop resistance, used p-wire wire clamp head is main at present
There are crocodile mouth formula and scissors hair style.Either crocodile mouth formula or scissors hair style wire clamp measuring head, in the test to contact surface,
Often there is problems with：
1. for flat-shaped contact surface, surface oxide layer must be brushed with wire brush, then is clamped on aluminum or copper terminal plate.
But for non-flat-shaped contact surface, such as tubulose, polyhedral etc., it is easy for occurring grip force not with the clamping of old wire clamp measuring head
It is enough, clamping is not tight, be difficult to break by the teeth surface layer oxide film the problems such as, to make occur on voltage or electric current in loop resistance test process
Not phenomena such as not going so that during loop resistance measures back and forth, delayed the repair time of a large amount of preciousnesses.
2. when test surfaces are located at thinner narrow position, and loop resistance investigate when detecting, with old line
Folder measuring head is stretched not into the exiguous space, or is put in jaw and be but difficult to open, and at this moment can only remove external component, such as outer
Cover, catch, baffle etc., then loop resistance measurement is carried out, unnecessary overhaul process together that this is undoubtedly again more.
3. in the test process of loop resistance, what most loop resistance borrowed is high altitude vehicle, but in high-altitude wagon box
When arm falls short of or high altitude vehicle is opened not into battery limits meadow, the loop resistance of certain extreme positions is tested, such as largely
Vertical knife in 1 disconnecting link of 220kV line bus side or 2 disconnecting links can only borrow at this moment if to measure whole group disconnecting link loop resistance
Scaffold, and commutation measures and removes simultaneously movable Scaffold again, which results in the dissipation for no reason of a large amount of repair times.And high-altitude
Measuring nearby lines or wire jumper induced electricity again can adversely affect measurement.
