Description
Technical field
The utility model relates to electrical equipment technical field, in particular to a kind of supply lines compact suspension clamp.
Background technique
In high voltage power transmission wire terminal, by supply lines, mutually mistake 600mm uses the parallel groove clamp of two same materials by two breakpoint joints
Get up, realize breakpoint electral junction, wire jumper is carried out using the connection type of " saddle " plus suspension insulator at the middle part of wire jumper
Suspension.Saddle hangs aluminium material (and the lower material of hardness) power transmission line, because of wind swing, excitation current swing, vibration etc.
Factor is easy to damage electric wire, may break when serious and cause power supply trouble.
As power industry becomes basically universal the pre- mode for cutting with scissors formula connecting strip connector at home, wire jumper hang is also by saddle
Suspension is changed to suspension clamp hang.
Suspension clamp is hung after wrapping up clue by nylon gum cover, then after winding clue with aluminium alloy stranded conductor package gum cover
On the insulator, hitch point is avoided to damage to clue bring.Pre- hinge formula connecting strip joint clamp reduces suspension after using
The problem of point set weight, and tensile strength improves about 8 times on the basis of parallel groove clamp.Above-mentioned suspension and clue continuation method
It is generallyd use in national power industry.
In railway power supply, for wire jumper by casting anchor and hitch point is limited, which can only meet installation 500- mostly
The pre- hinge formula joint clamp of 800mm, the pre- hinge formula joint clamp that domestic market is able to satisfy regulation electrical strength all exist
1000mm or more.In this case unit in charge of construction just by the truncation of the joint clamp of 1000mm type be 2 sections come using.It had been truncated
Wire clamp deformation itself is easily caused in journey, contact pressure halves after truncation, and transition resistance is multiplied, and tensile strength is seriously lost
It loses, occurs the power supply troubles such as Joint's falling off occur because the reasons such as burning, shaking in actual operation.
Formula connecting strip is cut with scissors in advance for 500mm the results showed being truncated, and electric current reaches 1010 peaces, at the duration 45 seconds, connects
Temperature reaches 152 degree when reaching 80 degree of aluminium material maximum operating temperature, 82 seconds, and specific test parameters is as follows:
| Current duration S | Connecting strip tap points temperature DEG C | Test current A |
| 0 | 25.4 | 0 |
| 45 | 80 | 1010 |
| 82 | 150 | 1010 |
| 135 | 160 | 1010 |
| 148 | 175 | 1010 |
| 178 | 180 | 1010 |
| 228 | 188 | 1010 |
| 282 | 191 | 1010 |
| 308 | 200 | 1010 |
| 338 | 220 | 1010 |
| 508 | 223 | 1010 |
| 556 | 235 | 1010 |
| 600 | 240 | 1010 |
Therefore it is badly in need of proposing the device together with the wire clamp reasonable combination of a kind of wire clamp by suspended portion and connecting part,
To solve the steady demand of hitch point and meet the mechanical strength and electrical strength of joint.
