Description
Technical field
This utility model relates to earth rod device field, particularly a kind of labour-saving same tower double back transmission line earth rod.
Background technology
Transmission line of electricity breaks down, and not only can affect commercial production and the daily life of the mankind, goes back the safe and stable operation of entail dangers to power system time serious.And same tower double back transmission line is less than single back line due to phase spacing, therefore run at multiple-circuit on same tower primary Ioops, during secondary circuit maintenance, due to electrostatic and electromagnetic coupled effect, operating loop can produce bigger induced voltage and faradic current in maintenance loop, can bring danger to maintainer.High-voltage earthing rod is one of common tool during ultra-high-tension power transmission line maintenance, is to be coupled together with the earth by power supply temporarily, to prevent the power circuit having had a power failure from due to former incoming call or faradisies suddenly of thus resulting in such as maloperations, maintainer is caused danger.Multiple-circuit on same tower one loop line road is run, and it is the important technical realizing safety inspection that two loop line road interruption maintenances hang high-voltage earthing rod.
Chinese patent " a kind of electric power overhaul with high-voltage earthing tool (CN103956595A) ", will be connected by a universal drive shaft between insulating bar and wire-hanging hook；Such that it is able to the angle changed between wire-hanging hook and insulating bar, can personnel convenient to operate at the wire of transmission line of electricity mounting different directions, improve the limitation of high-voltage earthing rod setting angle；Chinese patent " a kind of high-voltage earthing rod (CN202957369U) ", wire folder is connected on insulating bar by it by transition connector, wire folder is screwed connection with transition connector, wire folder can rotate in a circumferential direction on transition connector arbitrarily, it is easy to be aligned with transmission line wire, workable.But it does not all consider how to reduce operational forces when installing high-voltage earthing rod.
Existing high-voltage earthing rod patent, discharge because of the existence of induced voltage when all focusing on the operation of same tower double back transmission line one loop line road, two loop line road interruption maintenances, transmission line of electricity is made damage to occur, break in the problems such as stock, all do not consider that existing high-voltage earthing rod is to need certain dynamics success to install in installation process, especially when staff is on iron tower of power transmission line operation, easily allow staff have the retroaction of surplus energy to occur health unbalance, thus bring Personal Risk.The present invention is directed to how to make staff use the least strength just high-voltage earthing rod can be connected, propose a kind of labour-saving same tower double back transmission line earth rod, staff can be enable when working on tower, to keep balance, it is ensured that the life safety of staff.
Utility model content
This utility model provides a kind of for the operation of same tower double back transmission line one loop line road, two loop line road interruption maintenances, it is possible to operational forces required during effective reduction mounting earth rod, thus preferably ensure that the earth rod of the balance of operator.
In order to solve above-mentioned technical problem, the utility model proposes techniques below scheme: a kind of labour-saving same tower double back transmission line earth rod, it includes insulating bar, the top of described insulating bar is provided with metallic power wire clamp, the internal two sides of the coupler body of described metallic power wire clamp are separately installed with spring leaf, the lateral surface of described spring leaf is fitted with roller, and described roller constitutes rolling with power transmission line and coordinates, and described spring leaf is adopted and is made from an insulative material.
Described metallic power wire clamp is U-shaped hook-shaped.
Described roller uses high-abrasive material to make.
Described metallic power wire clamp is arranged on the top of insulating bar by the way of plug-in mounting, and is fixed it by pin, it is simple to dismounting.
Said two spring leaf is the most protruding, it is possible to clamping power transmission line.
The projecting portion height that described roller is arranged on spring leaf is less than 3-4mm.
Described roller is arranged on spring leaf as closely coupled installation 5-7.
This utility model has the advantages that:
1, pass through that multiple roller is installed on spring leaf and ensure that spring leaf is converted into rolling friction with power transmission line contact process by traditional friction that contacts, thus effectively reduce frictional force.
2, by by using dismountable pin feature to be attached between metallic power wire clamp and insulating bar, facilitating the dismounting of metallic power wire clamp.
3, the spring leaf being mounted opposite by design can effectively clamp power transmission line, and then ensures that in work process, metallic power wire clamp can effectively clamp power transmission line.
4, multiple-circuit on same tower one loop line road is run, two loop line road interruption maintenances easily install the problem that high-voltage earthing is excellent to use this device to be capable of, and can effectively reduce operational forces required when staff installs, enhance the safety of staff.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: spring leaf 1, metallic power wire clamp 2, insulating bar 3, roller 4, power transmission line 5, pin 6.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
As shown in Figure 1, a kind of labour-saving same tower double back transmission line earth rod, it includes insulating bar 3, the top of described insulating bar 3 is provided with metallic power wire clamp 2, the internal two sides of the coupler body of described metallic power wire clamp 2 are separately installed with spring leaf 1, the lateral surface of described spring leaf 1 is fitted with roller 4, and described roller 4 constitutes rolling with power transmission line 5 and coordinates, and described spring leaf 1 is adopted and is made from an insulative material.
Further, described metallic power wire clamp 2 is U-shaped hook-shaped.Ensure that normal spring leaf 1 of installing by U-shaped hook shape, and then ensure that device can clamp with power transmission line 5.
Further, described roller 4 uses high-abrasive material to make.Improve the service life of device by high-abrasive material, reduce the friction between itself and power transmission line 5.
