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 have an a large number of users equipment interruption maintenance, the earth connection chuck of use is not suitable with electric trestle column or does not meet the earth connection standard that electrical safety codes or grid company promulgate.In actual use, on side direction electricity row, long-term Misuse does not reach other alternative chucks of safety requirements and standard, causes potential safety hazard.
In operation, all kinds of electric pressure power transformation position in storehouse is put and side direction because of electric ranking, and former earth connection chuck is mostly right angle operation, is difficult to install, causes ground connection spacing inadequate.In existing various earth connection, sieve bar fastening-type chuck is right-angle type, and lever is lateral operation, is not suitable for the ground connection operation of existing power transformation, controller switching equipment.Domestic is at present all 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
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of safe and reliable, easy to operate straight and-clamping fastening earth connection of power transformation sieve bar is provided.
Object 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, arrange with equipment electricity and be connected, described earth connection comprises sieve bar, U-shaped main body, binding clip, wiring nose and earth lead, described sieve bar connects U-shaped main body and binding clip successively, described wiring nose one end is connected with U-shaped main body, the other end is connected with earth lead, and described binding clip is arranged with equipment electricity and is connected.
One end of described sieve bar is provided with screw thread, and described sieve bar is connected with U-shaped 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 matches, and the other end of wiring nose is fixed in U-shaped main body by set bolt.
One end that described binding clip is connected with U-shaped main body is provided with rise spring and cam block, and described cam block is arranged in U-shaped main body, and described binding clip is fixed in U-shaped 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, the contacting section arranged with equipment electricity is no less than specified value, there is reliable contact-making surface and the thermal stress and mechanical stress that amount fault current produces can be born, contact is good, substantially increase fail safe, have very important meaning to the person, device security;
2) easy to operate: the straight and-clamping fastening earth connection of power transformation sieve bar of the present invention can be installed on electricity row relatively easily, not only solve the position in storehouse problem with grounding of all kinds of distribution equipment, also can use this earth connection on the side direction electricity row equipment of any electric pressure simultaneously, also can operate from ground connection on 10 kv cable inlet wire bars.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is structural blast schematic diagram of the present invention.
Embodiment
