Background technology
Since use, the lightning-caused breaking of insulated conductor, lightning stroke trip problem annoying always 10kV insulated overhead conductors
Distribution operations staff.Area with more lightning activities and strong minefield in part, such as the Anhui south area in Anhui Province, even if installation lightning protection device, lightning protection effect
Fruit is not obvious, and lightning-caused breaking, lightning stroke trip, lightning protection device fire event and still happen occasionally.Lightning protection device is as aerial condutor
Important component part, core component are still distribution line arrester at present.Traditional distribution line 10kV zinc oxide
Residual voltage when arrester parameter is 5kA lightning impulse currents should be not more than 50kV, and residual voltage when switching impulse current should be not more than
42.5kV, residual voltage when steep impulse current are not more than 57.5kV.But when such as encountering small energy direct lightning strike, which just can not
Meet route protection requirement.Main cause, which is that nominal discharge current capacity is too small, causes arrester that can not protect.

Mixture and prefabricated silastic material tight bond, are finally packaged into arrester with shielding end cap；Arrester nominal discharge current
8/20 nominal discharge current of selection criteria is 10kA；The composite sheath of lightning-arrest element, including full skirt that at least five diameter is equal,
Full skirt is convex design, using the full skirt of convex design, can further increase creepage distance, is copied short caused by climbing electricity
Road；Plug in lightning-arrest element is by concatenated zinc oxide nonlinear resistance slice（Or valve block）It is made, and coated with coupling agent, through height
Temperature sulphurated siliastic vacuum pouring molding, makes the plug of lightning-arrest element and composite sheath form an entirety；Lightning-arrest element
Zero-clearance zinc oxide lightning arrester is used to carry out lightning protection, rated voltage 17kV, residual voltage 49kV for distribution suspended insulated guide wire；It keeps away
Thunder device uses the high-k resistor disc bigger than conventional, electric-resistance piece dielectric constant.
