Description
Technical field
The present invention relates to a kind of power station earth connection, especially relate to the straight and-clamping fastening earth connection of a kind of power transformation sieve bar.
Background technology
When transformer station, power distribution station had a large number of users equipment interruption maintenance, the inadaptable electricity of the earth connection chuck of use was arranged spacing or is not met the electric power safety standard or the earth connection standard of grid company promulgation.In actual use, long-term Misuse does not reach other alternative chucks of safety requirements and standard on side direction electricity row, has caused potential safety hazard.
In operation, all kinds of electric pressure power transformation positions in storehouse are put and side direction because of electric ranking, and former earth connection chuck is the right angle operation mostly, is difficult to install, and causes the ground connection spacing inadequate.Sieve bar fastening-type chuck is right-angle type in existing various earth connection, and lever is lateral operation, is not suitable for the ground connection operation of existing power transformation, controller switching equipment.At present domestic all is that spring directly presss from both sides, and its ground connection opening varies in size, and causes clamping section contact-making surface cross-sectional area of conductor not reach grounding requirement.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of safe and reliable, easy to operate straight and-clamping fastening earth connection of power transformation sieve bar for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
The straight and-clamping fastening earth connection of a kind of power transformation sieve bar, row is connected with the equipment electricity, described earth connection comprises sieve bar, U word main body, binding clip, wiring nose and earth lead, described sieve bar connects U word main body and binding clip successively, described wiring nose one end is connected with U word main body, the other end is connected with earth lead, and described binding clip is connected with equipment electricity row.
One end of described sieve bar is provided with screw thread, and described sieve bar is connected with U word main body by this screw thread, and the other end of described sieve bar is arranged with insulating case.
One end of described wiring nose is the hollow cylinder that the diameter of diameter and earth lead is complementary, and the other end of wiring nose is fixed on the U word main body by set bolt.
Described binding clip is provided with rise spring and cam block with the end that U word main body is connected, and described cam block is arranged in the U word main body, and described binding clip is fixed on the U word main body by two steady pins jointly with the spring that rises.
The maximum opening of described binding clip is 30mm.
The making material of described wiring nose is copper.
The making material of described binding clip is aluminium.
The Tightening moment of described binding clip is 14-28.
Compared with prior art, the present invention has the following advantages:
1) safe and reliable: the present invention adopts aluminium matter binding clip, be no less than specified value with equipment electricity row's contacting section, have reliable contact-making surface and can bear thermal stress and the mechanical stress that the amount fault current produces, contact is good, greatly improved fail safe, the person, device security have been had very important meaning;
2) easy to operate: the straight and-clamping fastening earth connection of power transformation sieve bar of the present invention can be installed on the electricity row relatively easily, not only solved the position in storehouse problem with grounding of all kinds of distribution equipments, also can on the side direction electricity row equipment of any electric pressure, can use this earth connection simultaneously, also can operate from ground connection on 10 kv cable inlet wire bars.
