Abstract
The invention relates to a 10kV-20kV distribution line discharge gap post porcelain insulator, which is characterized in that a wire clamp base is fixed at the upper part of the insulator in an adhesive mode, both sides of the wire clamp base are provided with a discharge arm, an arc groove at the middle of the wire clamp base is equipped with a plurality of ratchets, and two sides of the arc groove are screwed with two screws respectively; the screws are sleeved with a wire pressing plate, and an arc groove at the bottom part of the wire pressing plate corresponds to the arc groove of the wire clamp base; an insulated wire passes through the central arc grooves of the wire clamp base and the wire clamping plate, two torque nuts are tightened so as to clamp the wire, the ratchets can stab through an insulating layer of the wire so as to enable the discharge arms to be electrified; a lower steel feet of the insulator is provided with two arc striking balls which correspond to the discharge arms at the two sides of the wire clamp base above; and metal pieces such as the wire clamp base are covered by an insulating shield, and a discharge window is reserved at a discharge part of each bowl-shaped discharge arm. When lightning occurs, lightning stroke short-circuit arc energy is quickly transferred from the wire to a part between the discharge arm and the corresponding arc striking ball so as to trigger electric arc, thereby protecting the insulated wire from being damaged and protecting the porcelain insulator from being burned.
Description
Technical field
The present invention is the pillar porcelain insulator of distribution line, is directed to use with insulated conductor and prevents lightning-caused breaking.
Background technology
Along with the continuous propelling of distribution line insulating, the measure preventing insulated conductor breakage caused by lightning stroke is multifarious.Lightning surge punctures wire insulation and causes insulator arc-over, and puncturing place is Pinhole-shaped, and the arc root of lasting power frequency short circuiting arc burns at pin hole, and insulated conductor is very fast to be blown；Lightning-caused breaking has a strong impact on the safe operation of electrical network.The most thoroughly solve insulated conductor breakage caused by lightning stroke, be listed in relevant unit and capture one of emphasis.
Summary of the invention
The present invention is the pillar porcelain insulator that a kind of 10kV distribution line insulated conductor prevents lightning-caused breaking.
Technical scheme: it is characterized in that top wire pressing seat is fixed with porcelain insulator mucilage binding, wire pressing seat two side is respectively provided with electric discharge arm, its middle arc groove face is provided with in several little ratchets, two limit planes the two pieces of screw rods that are spirally connected；On its bottom screw, set is filled with wire pressing block, and bottom it, arc groove face is provided with several little ratchets；Insulated conductor, by the center arc groove of wire pressing seat with wire pressing block, is tightened two nuts and is held wire under the arm, and at this moment several little ratchets can pierce through the insulating barrier of wire up and down, makes wire pressing seat charged；The lower steel foot of porcelain insulator is provided with two striking balls, corresponding with the electric discharge arm of top wire pressing seat two side；When thunder and lightning hits then, thunderbolt short circuiting arc energy is transferred to discharge between arm and corresponding striking ball in very short time from wire, thus protects insulated conductor from damage, it is ensured that circuit is properly functioning.
Accompanying drawing explanation
Accompanying drawing 1 is present configuration figure.
In figure: wire pressing seat 1, wire pressing block 2, ratchet 3, insulating boot 4, insulated conductor 5, porcelain insulator 6, striking ball 7.
Detailed description of the invention
As it is shown in figure 1, porcelain insulator 6 is installed on cross-arm, its two side electric discharge arm towards should be same as wire trend,
Insulated conductor 5 is loaded on the middle arc groove of wire pressing seat 1, wire pressing block 2 is inserted on two pieces of screw rods of wire pressing seat 1, alternately tightens two torque nuts and holds wire under the arm to top fracture, it is ensured that ratchet punctures and puts in place, it is loaded on insulating boot 4, makes charged wire pressing seat 1, the capped protection of wire pressing block 2.
When being struck by lightning, the arc root of power frequency arc can be transferred to discharge on arm as quick as thought, and starting arc between electric discharge arm and striking ball 7, makes thunderbolt arc energy be exceedingly fast from wire and is transferred out, it is ensured that wire is from damage.
