Abstract
The invention discloses a connecting plate special for connecting a transmission line pole tower and a grounding network, which solves the problem that remote resistance detection has difficulty and hidden danger when the 35KV or more transmission line pole tower and the grounding network are connected and grounded. The connecting plate is characterized in that butted ends of a pole tower connecting plate 1 and a grounding network connecting plate 5 are provided with a link ring 8 and a connecting ring 7 respectively, one phi 18*50 screw 3 passes through the link ring 8 and the connecting ring 7, the other end of the screw 7 is provided with a matched phi 18*20 nut theft-proof ring 4, the pole tower connecting plate 1 is provided with a screw hole 2 for connecting the pole tower, and the grounding network connecting plate 5 is provided with two screw holes 6 for connecting the grounding network. The connecting plate can ensure quick and convenient operation, reduces various hidden dangers when the grounding network is connected with the pole tower, has positive effect on lightning protection of a transmission line, and is adaptive to connecting the 35KV or more transmission line pole tower and the grounding network.
Description
Technical field:
The present invention is specifically related to a kind of connecting plate special for connecting transmission line pole tower and grounding network, belongs to transmission line pole tower lightning-protection drainage ground network technical field, is adapted to 35KV and above electric power line pole tower and is connected with ground network and uses.
Background technology:
Known to inventor, current 35KV and above transmission line, due to the reasonability of the particularity of its designing technique and the restriction of modern society's rural and urban construction plans and joint Zhi Zengxiao, for a long time, the many places, location of overhead line structures are on high mountain high hill and between ridge slight slope, owing to being located in wilderness, geographical environment is in a disadvantageous position, guarantee unimpeded, the anti-lightning strike breaking work of circuit then become transmission line put into operation after important topic.For preventing thunderbolt, the every base shaft tower of builders to founded a capital circuit has carried out thunder and lightning drainage work---bury ground network underground, (according to engineering requirement, ground network generally adopts φ 8-φ 10 round steel to be welded by drawing, bury underground in the underground that 0.6M-0.8M resistivity is little subsequently, simultaneously termination reserves ground lead-in wire and connects with shaft tower, drainage object is reached) with this, earth mat drainage thread need connect with shaft tower, traditional manufacturing technique is that the other end welds with grounded round steels with the punching of 4mm*40mm*150mm band steel one end, punching one end and the pre-hole of shaft tower are formed by bolted.According to the requirement of line security operating standard, production division regularly should carry out ground network ground resistance to administrative circuit and shake survey work, and to overflowing, earth mat should be transformed in time, to prevent thunderstorm season circuit, thunderbolt breaking accident occurs.Shake in survey process at ground network ground resistance, we find that the earth mat drainage thread (being particularly in the earth mat in goaf and the soft district of geology) originally buried underground sinks due to geology change or backfill soil, often cause drainage thread to bounce back.Staff opens earth mat lead-in wire and shakes and survey after end-of-job, and it is quite difficult to recover connection work, and part earth mat lead-in wire even needs again to cut off after long earth mat lead-in wire is drawn in welding again can resume work.And the drainage thread previously recovered is due to human factor, the flexural deformation of part drainage thread, thus produce eddy current before causing thunder and lightning to flow into ground, impedance increases, and have a greatly reduced quality to the earial drainage function of earth mat, line thunder protection work exists numerous hidden danger.Not yet find that there is the device improving its operation principle at present, also there are no pertinent literature report and record.
Summary of the invention:
Object of the present invention is exactly for overcoming above defect, and what provide a kind ofly solves current ground network ground resistance and shake the difficulty and hidden danger that exist in survey work, alleviates a kind of connecting plate special for connecting transmission line pole tower and grounding network of the labour intensity of working member simultaneously.
The present invention adopts following technical scheme to realize: described a kind of connecting plate special for connecting transmission line pole tower and grounding network, comprise a block length square connection shaft tower yoke plate 1 to be connected earth mat yoke plate 5 with one piece and to form, it is characterized in that being respectively arranged with chain T-Ring 8 and connecting ring 7 at connection shaft tower yoke plate 1 with the docking termination being connected earth mat yoke plate 5, φ 18*50 screw rod 3 one is set through chain T-Ring 8 and connecting ring 7, the φ 18*20 nut anti-theft circle 4 of coupling is set in another termination of screw rod 3, connection shaft tower yoke plate 1 arranges a connection shaft tower screw hole 2, connection earth mat yoke plate 5 arranges two and connects earth mat screw hole 6, it is 5*50*100mm that connection shaft tower yoke plate 1 arranges specification, it is 5*50*150mm that connection earth mat yoke plate 5 arranges specification.Electric power line pole tower lightning protection drainage ground network device of the present invention, be specially 35KV and above connecting plate special for connecting transmission line pole tower and grounding network, the many difficulties and actual hidden danger that exist in survey work is shaken in order to solve current ground network ground resistance, alleviate intensity of workers simultaneously, increase work efficiency.
A kind of connecting plate special for connecting transmission line pole tower and grounding network of the present invention, has yoke plate length and meets the on-the-spot syndeton length requirement of ground network drainage, reach between two band steels and overturn freely, simple and direct economy, and work advantage that is flexible, practical and effect.
Accompanying drawing illustrates:
Accompanying drawing is a kind of connecting plate special for connecting transmission line pole tower and grounding network structure chart
In figure: 1. connect shaft tower yoke plate, 2. connect shaft tower screw hole, 3. lead screw, 4. nut anti-theft circle, 5. connect earth mat yoke plate, 6. connect earth mat screw hole, 7. chain T-Ring, 8. connecting ring,
Embodiment:
Below in conjunction with accompanying drawing, the present invention is described in further detail for embodiment, a kind of connecting plate special for connecting transmission line pole tower and grounding network as shown in the figure, first by one piece of band steel (5*50*150) and the band steel φ 16*35 screw joints that ground network drainage thread welds during installation, and then be connected with another block band steel (5*50*100) with φ 18*50 bolt, it is fastening that bolt passes band steel welded nut part φ 18 pilfer band, because yoke plate length meets the on-the-spot syndeton length requirement of ground network drainage, reaching between two band steels overturns freely, simple and direct economy, flexible and the practical effect of work.
The presentation quality and the working stress that check each pad is needed before installation.
Need during installation to smear enough conductive pastes at each interface place, to guarantee conductivity and the flexibility of each connection place.
