Description
Technical field
The utility model relates to the preformed sub-lead spacer of a kind of overhead transmission line Anti-galloping Interphase interval, belongs to overhead transmission line and to transmit electric power technical field.
Background technology
Along with the frequent appearance of exceedingly odious weather, 500kV compact line frequently waves breaking in recent years, serious threat electric power netting safe running.Installing inter-phase spacer is between the conductors the effective measures that line oscillation is administered, by mutually pining down between wire, to reach the object destroying wire stable vibration.The inter-phase spacer six oidiospore lead spacer of background technology, comprise inter-phase spacer main body and support, and described support one end connects inter-phase spacer, other end connexon lead spacer main body.Inter-phase spacer is by connecting installation on overhead transmission line sub-lead spacer, in conductor galloping process, inter-phase spacer was both subject to tensile load, was also squeezed and bending load, and this active force is delivered on overhead line conductor by sub-lead spacer.Therefore the sub-lead spacer being provided with inter-phase spacer will be regular to overhead line conductor apply alternation/impulse machine load, waving the frequent region occurred, prevent overhead transmission line from waving even if installed inter-phase spacer, sub-lead spacer continuation, regular to wire apply alternation/impulse machine load will cause overhead line conductor fatigue damage or disconnected stock, even there is conductor cord disconnection when serious to land, jeopardize power grid security reliability service.
Utility model content
The utility model object is to provide the preformed sub-lead spacer of a kind of overhead transmission line Anti-galloping Interphase interval; with the stress disperseing inter-phase spacer to be delivered to wire; effectively protect overhead transmission line, guarantee overhead transmission line safe and reliable operation, solve Problems existing in background technology.
The technical solution of the utility model is:
The preformed sub-lead spacer of a kind of overhead transmission line Anti-galloping Interphase interval, comprises sub-lead spacer main body, preformed armor rods, preformed armor rods wire clamp and rubber packing layer; Sub-lead spacer main body is provided with between two adjacent aerial condutors; Aerial condutor wraps up rubber packing layer, preformed armor rods turns to helix, is wrapped in the aerial condutor outer surface having wrapped up rubber packing layer, and preformed armor rods and aerial condutor and rubber packing layer are fixed as one; Arrange preformed armor rods wire clamp outside preformed armor rods, rubber packing layer is positioned at preformed armor rods wire clamp place; Be connected by preformed armor rods wire clamp between sub-lead spacer main body with adjacent two aerial condutors.
Described sub-lead spacer main body and adjacent two aerial condutors are arranged vertically, and the two ends of sub-lead spacer main body are connected with the preformed armor rods wire clamp on adjacent two aerial condutors respectively.
The utility model is applied in the position needing to install inter-phase spacer, plays minimizing alternation/impulse machine load, the effect of fender bracket hollow wire.
Rubber packing layer of the present utility model is wrapped on aerial condutor, preformed armor rods turns to helical wound and is also fixed on the aerial condutor having wrapped up rubber packing layer, increase the lifting surface area between aerial condutor and sub-lead spacer main body preformed armor rods wire clamp, make aerial condutor stressed more even.Meanwhile, under the protection of wrapped up rubber packing layer and preformed armor rods, alternation/impulse machine load reduces greatly, plays the effect of available protecting aerial condutor.
The beneficial effects of the utility model: change sub-lead spacer main body and wire adopts rigidly connected mode, add preformed armor rods and rubber packing layer, connected mode is become and flexibly connects, effectively reduce overhead transmission line inter-phase spacer by sub-lead spacer main body continuation, regularly to alternation/impulse machine load that wire applies.Preformed armor rods is added between sub-lead spacer main body and aerial condutor; increase effectively the lifting surface area of aerial condutor; make alternation/impulse machine load diatibution more even, eliminate stress to greatest extent and concentrate, can mechanical damage and fatigue be avoided to break the situations such as stock by available protecting aerial condutor.Structure is simple, and reliability is high, and can adapt to strong wind and take place frequently, wave serious comparatively rugged environment, effective guarantee aerial condutor safety, guarantees overhead transmission line safe and reliable operation.
