Abstract
The invention discloses a novel ground wire preventing inducted electricity damage. The ground wire comprises a grounding end, a three-phase single-conductor short-circuit ground wire is divided from the grounding end, two phase wires are also divided from each phase of the single-conductor short-circuit ground wire, and a first head restraint, a second head restraint, a third head restraint, a fourth head restraint, a fifth head restraint and a sixth head restraint are connected with the phase wires. According to the novel ground wire preventing the induced electricity damage, one phase wire and one head restraint are additionally arranged at each phase of a conventional three-phase single-conductor short-circuit ground wire, each phase of the ground wire is provided with two head restraints, single-phase double-wire dual grounding is realized, the problem of damage caused by inducted electricity to people is effectively solved, and the life safety of maintenance personnel is effectively protected.
Description
Technical field
The present invention relates to power domain, be specially a kind of anti-induced electrical injury Novel connecting ground wire.
Background technology
Electric power safety working regulation specifies: for ensureing staff's life security, prevent power failure equipments from sending a telegram here suddenly or produce the faradism injury to people, working on power circuit or high pressure equipment and must install earth lead, installing earth lead is also to ensure that important technical measures in work about electric power safety.In recent years; there is a lot of life casualty accident caused due to faradism in grid maintenance work at home; through accident analysis, the main cause of faradism personal injury is caused to have 3 points: one is to cause maintenance circuit or repair apparatus to lose ground protection owing to the dop of earth lead is surprisingly come off by external force；Two is owing to maintainer's mobile grounding line card head without authorization causes maintenance circuit or repair apparatus moment to lose ground protection；Three is due to job demand, and joint or the repair apparatus of maintenance circuit are connected wire clamp and open by maintainer accidentally, cause the side of maintenance circuit or repair apparatus to lose ground protection.Through Investigation and Analysis: the earth lead that current domestic high-voltage fence inspection and repair shop is selected is all for the three-phase single line short circuit earth lead made by multiply annealed copper wire, a dop is installed in i.e. every mutually single shorting stub, the side of three shorting stubs is equipped with three dops respectively, and three shorting stub opposite side short circuits merge one as earth terminal.The life security of protection maintainer when the type earth lead is widely used in the maintenance of domestic high-voltage fence at present; and the type earth lead is in use; when running into 3 reasons of above accident analysis, it is impossible to safely and effectively protect the life security of maintainer.
Summary of the invention
It is an object of the invention to provide a kind of anti-induced electrical injury Novel connecting ground wire, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of anti-induced electrical injures Novel connecting ground wire, including earth terminal, described earth terminal separates three-phase single line short circuit earth lead, every phase single line short circuit earth lead separates again two phase lines, and described card is first, dop two, dop three, dop four, dop five and dop six are connected in phase line.
Preferably, described card is first, on dop two, dop three, dop four, dop five and dop six point
It is not provided with buckle.
Compared with prior art; the invention has the beneficial effects as follows: this anti-induced electrical injury Novel connecting ground wire; every at traditional three-phase single line short circuit earth lead is further added by a phase line and dop mutually; every phase earth lead installs two dops; realize single phase two-line dual grounds; efficiently solve the problem that faradism is hurted sb.'s feelings, thus effectively protect the life security of maintainer.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
In figure: 1-earth terminal, 2-card are first, 3-dop two, 4-dop three, 5-dop four, 6-dop five and 7-dop six.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1; the present invention provides a kind of technical scheme: a kind of anti-induced electrical injures Novel connecting ground wire; including earth terminal 1; described earth terminal 1 separates three-phase single line short circuit earth lead; every phase single line short circuit earth lead separates again two phase lines, and so every phase earth lead installs two dops, it is achieved single phase two-line dual grounds; efficiently solve the problem that faradism is hurted sb.'s feelings, thus effectively protect the life security of maintainer.Described card is first 2, dop 23, dop 34, dop 45, dop 56 and dop 67 are connected in phase line.Described card is first 2, be respectively arranged with buckle on dop 23, dop 34, dop 45, dop 56 and dop 67, the more easily handling of dop.
Operation principle: during maintainer's service work; two phase lines often gone up mutually are connected on three circuits respectively by two dops; the other end of phase line is connected on the ground by earth terminal; thus realize single phase two-line dual grounds; solve the problem in background technology, such as: cause maintenance circuit or repair apparatus to lose ground protection owing to the dop of earth lead is surprisingly come off by external force；Owing to maintainer's mobile grounding line card head without authorization causes maintenance circuit or repair apparatus moment to lose ground protection；Due to job demand, joint or the repair apparatus of maintenance circuit are connected wire clamp and open by maintainer accidentally, cause the side of maintenance circuit or repair apparatus to lose ground protection, and the present invention each joint both sides are respectively arranged with two dops i.e. will not produce faradism.
Although an embodiment of the present invention has been shown and described, for member of ordinary skill in the art, being appreciated that and these embodiments can carry out multiple change without departing from the principles and spirit of the present invention, revise, replace and modification, the scope of the present invention be defined by the appended.
