Description
Technical field
The utility model relates to a kind of equipotential transferring stick, relates in particular to a kind of 1000kV extra-high voltage AC circuit strain tower Ω type equipotential transferring stick.
Background technology
Electric potential transferring stick is the metal tools that the equal potential working personnel use when passing in and out equipotential, is used for reducing electrical discharge arc to the impact of human body and the damage of avoiding pulse current may cause shielding clothing.According in " 1000kV transmission line of alternation current live line working technology guide rule " and " State Grid Corporation of China electric power safety work regulation " to the regulation of 1000kV ultra high voltage potential transfer, the staff carries out live line working in the 1000kV transmission line of alternation current and should use electric potential transferring stick to carry out potential transfer, and potential transfer length is 0.4m; The equal potential working personnel should obtain work director's license before potential transfer, when fastening the safety electric bit transition, human body face and electrified body distance must not be less than 0.5m; When equipotential electrician carried out potential transfer, electric potential transferring stick should be electrically connected with shielding clothing.
Through inquiry, at present the domestic 1000kV extra high voltage line of carrying out enters equal potential working along strain insulator string and only has Henan ehv power transmission fortune inspection company to carry out in extra-high voltage experiment base, Wuhan on June 22nd, 2011.In operation process, shifting current potential moment and the nearest electrified body of equal potential working personnel is the ring body of grading ring, ring body diameter 120mm, and existing equipotential transferring stick chuck opening is about 40mm, can't be stuck on the ring body of grading ring, can only be stuck on the ramuscule support of grading ring.The distribution because ring body and bracing frame meet at right angles substantially need to be passed ring body and be hooked bracing frame with electric potential transferring stick when the equal potential working personnel enter equipotential, install very inconveniently, the phenomenon that hook does not live occurs easily.Withdrawing from equipotential moment, the guiding line direction that needs electric potential transferring stick moves very large stroke and just can take off, equal potential working personnel's arm need to put in a part in the ring body, and at this moment the safe distance of the 0.5m of human body face and electrified body should not be controlled, and has great potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of 1000kV extra-high voltage AC circuit strain tower Ω type equipotential transferring stick, be applicable to the 1000kV extra-high voltage AC circuit and enter equal potential working along strain insulator string, can guarantee staff's personal safety, avoid security incident.
The utility model adopts following technical proposals:
A kind of 1000kV extra-high voltage AC circuit strain tower Ω type equipotential transferring stick, comprise that length is not less than the insulative tubular handle of 50cm, one end of handle is provided with the elastic metallic chuck of conduction, metal collet connects the copper cash that is arranged in the handle, the sectional area of copper cash is not less than 16mm2, and the tail end of copper cash is provided with the shielding clothing connecting hole.
Described metal collet is the Ω type elastic metallic chuck that is provided with opening.
Described Ω type elastic metallic chuck adopts austenitic stainless steel thin plate to make, and the thickness of austenitic stainless steel thin plate is 2mm, and width is 25mm.
The length of described insulative tubular handle is 50cm.
Be provided with strand copper wire in the described insulative tubular handle.
Described strand copper wire is arranged in the transparent sheath.
The utility model utilizes the electrically conductive elastic metal collet that arranges on the equipotential transferring stick to block press-ring body, effectively solved the problem that existing equipotential transferring stick can't use along strain insulator string at the 1000kV extra high voltage line, simple in structure, lightweight, be easy to carry, easy to operate, can guarantee staff's personal safety, avoid security incident.
