Abstract
The utility model relates to an earth wire with the electric testing function. The earth wire is mainly composed of an insulating rod (4), a hook (6) and an electroscope (1) (as the accompanying drawing of a specification shows), wherein, the hook (6) is installed on one end of the insulating rod (4), and the electroscope (1) is installed on the other end of the insulating rod (4). When the electroscope works, the hand holds one end of the insulating rod (4) to enable the electroscope (1) to contact a conducting wire and the end of the insulating rod (4) is provided with the hook (6). Afterward, the hand holds one end of the insulating rod (4) to enable the hook (6) to be hung the conducting wire and the end of the insulating rod (4) is provided with the electroscope (1).
Description
The utility model relates to a kind of short-circuit grounding wire that is used for high-voltage electric power system.
In electric power system, when the high-tension line interruption maintenance, in order to ensure maintainer's personal safety, regulation must be used earlier the electroscope electrical verification, after the confirmation circuit has had a power failure really, hangs up properly earth connection in the both sides, job site then, just can enter work on the spot at last.But in practical operation,, often save with this operating procedure of electroscope electrical verification because operating personnel follow the line of least resistance, and direct hanging earthing conductor on the circuit, so that cause the serious accident of charged hanging ground-wire sometimes.
For preventing the generation of this type of accident effectively, I have proposed technical scheme that electroscope and earth connection are made of one in 91223718.X.Though this scheme can be finished " first electrical verification is hanging earthing conductor again " these two job steps for operating personnel and bring certain convenience, use and carry inconvenient this shortcoming but still exist.
The purpose of this utility model is exactly that a kind of improved earth connection with electroscope function will be provided, and it not only can prevent the generation of charged hanging ground-wire accident effectively, and easy to use and carry.
The purpose of this utility model is achieved in that and adopts an insulating bar, and the hook that annealed copper wire is housed is contained in an end of insulating bar, electroscope is contained in the other end of insulating bar.During electrical verification, hand-held insulating bar is equipped with an end of hook, electroscope is contacted with lead get final product; Then, hand-held again insulating bar is equipped with a galvanoscopic end, and hook is hung on the lead.
The utility model is compared with 91223718.X, because electroscope is retrofitted to the insulating bar lower end, so its structure is more simple, and cost is lower, uses and carry also to make things convenient for.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is according to a kind of structural representation that the utility model proposes, below in conjunction with its general configuration of description of drawings and using method.
In the accompanying drawing: electroscope (1) is housed in the lower end of insulating bar (4); Metal contact (2) and acousto-optic indicating device (3) are housed on electroscope (1); The upper end of insulating bar (4) joins by threaded portion and the hook (6) that has annealed copper wire (7); The top of pressing plate (5) and insulating bar (4) be engaged togather ［ annotate: the top of insulating bar (4) turns pressing plate (5) below ］.When needing electrical verification, hand-holdable insulating bar (4) has an end of hook, and metal contact (2) is contacted with lead.By the acousto-optic indicating device, whether charged with regard to the decidable lead.When needing hanging ground-wire, hand-holdable electroscope (1) one end will be linked up with (6) and hang on the lead, and firmly rotate insulating bar (4).Because insulating bar (4) adopts between (6) with hook and is threaded, so along with the relatively rotating of insulating bar (4), its top promptly promotes pressing plate (5) and moves up, until lead is compressed.Behind the end-of-job, turn insulating bar (4) again, drive pressing plate (5) and move down, so that hook (6) is taken off from lead.
For pressing plate (5) and hook (6) are kept in one plane, be provided with gathering sill at the left end of pressing plate (5), so that pressing plate (5) can only move up and down.
From the above mentioned, finish " first electrical verification, back hanging earthing conductor " these two courses of work, only need be switched earth connection once in hand and get final product.
Electroscope belongs to present existing procucts, and its concrete structure omits at this.
Claims (1)
- A kind of earth connection with electroscope function, this earth connection mainly are made up of insulating bar, electroscope and hook, it is characterized in that linking up with an end that is contained in insulating bar, and electroscope is contained in the other end of insulating bar.
