Description

The short-circuit grounding wire that has electroscope function

The utility model relates to a kind of electric equipment (particularly electric line, below identical) maintenance safety device, especially a kind of short-circuit grounding wire with electroscope function.

Short-circuit grounding wire is the basic security measure that must take when carrying out interruption maintenance on electric equipment, it is except discharging the residual electric energy of high-voltage electrical equipment, prevent to respond to outside the harm with distant place thunder and lightning, more important be when the misdelivery electricity occurring (when sending a telegram here suddenly) it is last one outpost of the tax office of guaranteeing staff's personal safety.Therefore, short-circuit grounding wire is referred to as " line of saving one's life ".Pertinent regulations according to " electrical safe working order " of promulgated by the ministries or commissions of the Central Government of state's household electrical appliances industry: on the electric equipment that has a power failure before the installing short-circuit grounding wire, must be at first with qualified, the special-purpose electroscope of relevant voltage grade is to the electric equipment electrical verification, have only after identifying true no-voltage, could install the short circuit ground wire.Obviously, electrical verification, to articulate short-circuit grounding wire be requisite safety measure in the interruption maintenance process.But at present because electroscope and short-circuit grounding wire are two covering devices independent of each other, in actual mechanical process in the especially work high above the ground process, often need to transmit electroscope and short-circuit grounding wire back and forth with rope, and the operation of the electrical verification that need make two bites at a cherry, ground connection, thereby operator's the labour intensity and the danger of work high above the ground have been increased.Existing in addition electroscope action bars does not have earthing device, has unsafe factor yet.Particularly in actual mechanical process, owing to leave behind electroscope, dislike trouble and be reluctant electroscope pulled on and leave behind, or shift working face again after the electrical verification for the first time, ground connection and inconvenience is taken multiple reasons such as electroscope again, cause without the electrical verification phenomenon ubiquity of suspension earth connection on electric equipment just.And this bad habit is difficult to radical cure to a great extent for the moment, consequently step on charged shaft tower etc. because of mistuning degree, misoperation, mistakenly entering charged chamber, mistake, accidents such as the loss of life or personal injury that lead to therefrom happen occasionally, and cause loss and the disaster that can't retrieve for society, enterprise and family.

The purpose of this utility model is to overcome above defective, provides a kind of and can effectively avoid accident such as loss of life or personal injury to take place and can alleviate operator's labour intensity, reduces the short-circuit grounding wire that has electroscope function of the danger of work high above the ground.

The purpose of this utility model is achieved in that a kind of short-circuit grounding wire that has electroscope function, comprise: the ground connection action bars that is provided with the hanging wire wire clamp, two ends connect the short-circuit line and the ground lead of hanging wire wire clamp and earth electrode respectively, be characterized in: the other end at the hanging wire wire clamp of ground connection action bars is that afterbody is provided with electroscope, electroscope and hanging wire wire clamp are the part of two mutually insulateds, and electroscope and ground connection action bars afterbody are for flexibly connecting.

Described electroscope can adopt an acoustooptical electroscope and a rotation electroscope to connect mutually.

Described electroscope and ground connection action bars afterbody flexibly connect and can adopt in the movable centre bore that inserts ground connection action bars afterbody of electroscope plug, and by the structure of spring pearl location.

Can adopt folding joint to be connected between electroscope plug and the electroscope.

Be respectively equipped with an insulated handle and retaining ring (the spacing sign of handle) at the ground connection action bars near the position that the position and the action bars hanging wire wire clamp other end of hanging wire wire clamp is afterbody.

During operation, the operator is at first with short-circuit line and the ground lead and earth electrode (tower grounding net) reliable ground of attended operation bar hanging wire wire clamp, then, the insulated handle of hand-held operation bar hanging wire wire clamp one end, electroscope is contacted electric equipment (lead that comprises circuit) electrical verification towards the top, after the electrical verification action bars fallen turnback, action bars and short circuit ground wire are hung on the electric wire.If three-phase operation is then dialled down the tail end that electroscope inserts the another action bars again, so by phase electrical verification, ground connection.

Owing to adopt above structure, the utlity model has following remarkable advantage and good effect: the most appropriate position of action bars that, electroscope reasonably is installed in short-circuit grounding wire, two kinds of security apparatus are combined together, two operations unite two into one, reduced the present intermediate link that both separate, thereby eliminated because of personnel's carelessness of working waits and not to be with or need not galvanoscopic possibility, for radical cure just provides material guarantee in the bad habit of (particularly on the electric line) suspension earth connection on the electric equipment without electrical verification.Reduced present electrical verification simultaneously, (in the operating process) time interval that ground connection needs that two procedures, two steps finish, can avoid the danger of incoming call suddenly in the operating process effectively, comprehensive These characteristics can fundamentally be avoided the generation of accidents such as loss of life or personal injury effectively.Two, because each end of the hanging wire wire clamp of electroscope and earth connection at action bars, two operations of electrical verification and short circuit ground connection are not disturbed mutually, therefore, handling safety is reliable, simple and easy to do, and this short-circuit grounding wire that has electroscope function has limited from utensil and will connect earth terminal (earth terminal that connects earlier that meets " electric industry safety regulations " defined connects conductor wire end again) earlier, therefore action bars is a ground connection in the process of electrical verification, this moment is if the charged and action bars of circuit is because of making moist or reason such as material own causes under the situation of dielectric strength reduction, can avoid the injury of induced electricity effectively to the operator, with the special-purpose electroscope of present use essential difference and significant advantage are arranged relatively, eliminated potential safety hazard.Three, reduce operator's labour intensity to a great extent, reduced the danger of high aerial operating personnel's repeatable operation simultaneously.Four, since electrical verification, ground connection shared an action bars, compare with present employed electroscope short-circuit grounding wire, cost only is half.
