Description
Technical field
The utility model relates to a kind of lightning arrester, relates in particular to the multi-functional lightning arrester of a kind of overhead transmission line adjustable clearance.
Background technology
Lightning arrester is mainly used in limiting atmospheric over-voltage, is generally used for distribution system, circuit and inlet wire of substation segment protect.
In reality, when overhead transmission line meets with after thunderbolt, lightning voltage can find an insulation weak link that insulating barrier moment is punctured, and produces thunder and lightning electric arc.Electric arc, on plain conductor, can, because of electrodynamic effect, be moved to load side by mains side, and the heat that electric arc produces is disperseed rapidly, generally can not make in this case plain conductor cause fatal damage; But on insulated conductor, due to the obstruct of insulating coating, electric arc cannot move, and power frequency arc concentrates on the breakdown point of insulating barrier, therefore as easy as rolling off a log initiation circuit fusing broken string and trip accident, and and then affect the performance of equipment and the operation process of factory.
Prevent at present that the major measure that suspended insulated guide wire is taked by thunderbolt from having both at home and abroad: zinc oxide arrester is installed, set up overhead ground wire, install striking wire clamp etc. additional, although above measure also can effectively reduce thunderstruck risk, then the product structure more complicated being applied to due to above-mentioned measure, concerning staff, install extremely inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provides a kind of simple in structure, and at the aerial simple installation of height, quick, the safe and reliable to operation multi-functional lightning arrester that is applicable to overhead transmission line, this lightning arrester has the adjustable function in protection gap.
For achieving the above object, the utility model adopts the multi-functional lightning arrester of a kind of overhead transmission line adjustable clearance, comprise lightning arrester main body, upper support plate, lower support plate, stud, abnormity puncture bolt clamp and upper ball discharge and lower striking ball, between described upper support plate and lower support plate, fixedly mount and form fixed support by stud, described abnormity puncture bolt clamp is arranged on described support bracket fastened upper support plate, described upper ball discharge and lower striking ball are arranged in described fixed support, and between described upper ball discharge and lower striking ball, form protection gap, in conjunction with practical experience, the distance in general protection gap is between 15-25mm, the two ends up and down of described lightning arrester main body have respectively the first threaded post and second threaded post of protrusion, described the first threaded post is through described lower support plate and fix this lower support plate by the first nut, and then form the fixed installation of described fixed support in described lightning arrester main body upper end, in described the first threaded post, be also provided with adjustable nut, on described lower striking ball, offer screwed hole, and this screwed hole and described the first threaded post adaptation, described adjustable nut is arranged between described the first nut and lower striking ball, and this adjustable nut forms the position-limiting action to lower striking ball.
Further preferred, described abnormity puncture bolt clamp has wire clamp pedestal and clamp nut and circular cone acupuncture, described wire clamp pedestal has U-shaped trunking, and described hold-down bolt forms adjustable being threaded with described wire clamp pedestal, and described circular cone acupuncture is arranged on described clamp nut below.
By the above-mentioned improvement to prior art, the multi-functional lightning arrester of overhead transmission line adjustable clearance of the present utility model has reached the beneficial effect of following three aspects:: 1, because being threaded connection successively, adjustable nut and lower striking ball be fixed in the first threaded post, therefore can form effectively spacing (because the protection gap in reality is generally just enough between 15-25mm to lower striking ball by the mode of adjustable nut being carried out in the first threaded post to precession or back-out, the adjustable extent of the adjustable nut that therefore we set is generally in 10mm left and right), and and then realize to protection clearance distance adjusting, known in sum, because protection of arrester clearance distance of the present utility model is adjustable, therefore engineering staff can carry out discharging gap adjusting according to local geographical conditions and weather condition, make the applicability of lightning arrester of the present utility model stronger, 2,, lightning arrester of the present utility model is because there being the buffer action in protection gap, so can not cause short circuit grounding, move more safe and reliable, during without overvoltage, unit of an arrester body is at ordinary times in " rest " state, so also extended the useful life of lightning-arrest component body, 3, due to the abnormity puncture bolt clamp employing clamp nut of lightning arrester of the present utility model and the compressing structure of circular cone Acupuncture, therefore, in the time that lightning arrester need to connect wire, do not need the insulating barrier of wire to peel off, and can directly wire be put into trunking, then drive circular cone acupuncture guiding line position to exert pressure by hold-down bolt, and then circular cone acupuncture insertion wire insulating barrier and realize effective connection, the setting of this structure efficiently solves the bad problem of wire water-tight, can not affect wire machinery carries and stretches performance and used life simultaneously, and minimizing obviously installation personnel need the operation of wire stripping, improve greatly the operating efficiency of installation personnel.
