Description
Technical field
The utility model is related to a kind of large distance porcelain insulators of spontaneous heating anti-ice-flashing.
Background technology
The icing phenomenon of transmission line of electricity often occurs due to winter cold for the city in China the north, in recent years, because of icing
It causes the major accident that insulator arc-over tripping occurs for transmission line of electricity repeated, not only causes huge economic loss, and
And the safe operation of power grid and the normal life of the masses are seriously affected.Therefore, delay to cover when transmission line of electricity forms icing
Ice ice slush bridging time and raising icing Power Flashover Voltage, the safe operation for ensureing transmission line of electricity are very necessary.At present
Cope with icing and caused by accident, counter-measure is mainly the length of lengthened insulative substring to improve flashover voltage, this mode
It is required that abolish original shaft tower then founds tower again, increases line corridor channel floor space, cause improvement cost higher, it is very multiple
Miscellaneous and inconvenient, simultaneously because birds stop falling above high voltage iron tower insulator, defecation pollutes insulator, cause single-phase earthing or
Make electrical body that the air gap be caused to puncture, line tripping accident is caused to occur again and again.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of large distance porcelain of spontaneous heating anti-ice-flashing
Insulator.
To achieve the above object, the technical solution adopted in the utility model is：The large distance porcelain insulating of spontaneous heating anti-ice-flashing
Son, including mandrel, be coated on the outside of mandrel full skirt group, heat absorption deicing device, support block, be fixed on dripping at the top of support block
Eaves, connecting rod, brush board, steel cap, bearing, flabellum and extension rod.It is equipped with steel cap, support on the outside of the mandrel successively from top to bottom
Block, full skirt group and heat absorption deicing device, the bearing are set on the outside of steel cap, and the flabellum is fixed on bearing two by extension rod
Side, the brush board are fixed by the connecting rod in the lower end of bearing.The full skirt group is evenly spaced to be set on mandrel, the heat absorption
Deicing device is set between adjacent full skirt group.The heat absorption deicing device includes the absorber plate set gradually from outside to inside, infrared
Line fever crystal, insulating layer and thermal conductive silicon, the exothermal infrared crystal outside are equipped with absorber plate, and inside is equipped with insulating layer, institute
It states and is coated on mandrel by thermal conductive silicon on the inside of insulating layer.
Preferably, the connecting rod is parallel with dripping eaves.
Preferably, the full skirt group includes the first umbrella piece and the second umbrella piece.
Preferably, the first umbrella piece and the second umbrella piece lower surface are uniformly provided with wavy male and fomale(M&F).
Preferably, the dripping eaves end is equipped with heat-absorbing block.
The utility model is simple in structure, reasonable design.Using the alternate full skirt group of large and small umbrella, while umbrella body bottom uses
Corrugated male and fomale(M&F) increases creepage distance in the case that umbrella piece quantity is identical, and pollutant is made to be not easy to fall on umbrella body
Centre, and the phenomenon that cause dust stratification, to keep the cleaning of insulator.Dripping eaves can help the evenly dispersed drop of the soiling solutions such as rainwater
It falls, and the heat-absorbing block of dripping eaves end can absorb heat and prevent from generating ice slush on dripping eaves.Wind-force is collected by flabellum, is driven
Birds droppings or sundries at the top of the brush board cleaning dripping eaves of bearing bottom, while brush board ceaselessly rotates can frighten birds, prevents
Birds are stopped.Heat absorption deicing device changes the phenomenon that insulator chain flashover trips caused by icing.
