Described insulation rod two ends are connected respectively by bolt one end with insulation rod attaching parts, and the other end of insulation rod attaching parts is embedded into the inner of bus-bar joint and is bolted fixing; The middle part of described long slide plate, short slide plate connects by double end stud, spacing screw collar the both sides being positioned at bus-bar joint respectively, and afterbody is separately fixed at the both sides of bus-bar joint by bolt.
Described long slide plate, short slide plate adopt Cu alloy material, and arcing born adopts stainless steel.
Described insulation rod is made up of Fiber glass rod core body and the sulphurated siliastic full skirt being coated on Fiber glass rod core surface.
Described insulating slide is supported by SMC compound material insulation slide way body and glass fiber reinforced polyester resin and anchor ear is formed.
The advantage that the utility model compared with prior art has and effect:
1, the utility model insulating slide is arranged on both sides immediately below composite insulation rod and discontinuous, not only simple and compact for structure, and mounting and adjusting is convenient, and particularly two insulating slides are provided separately, be disconnected leakage current, ensure that composite insulation rod creep distance reaches 1600mm.In addition ensure pantograph by time at least two-point contact, before avoiding bi-directional segmented single-contact cause pantograph by time deflection potential safety hazard; And bottom contact wire with slide plate bottom, contour bottom insulating slide, ensure that pantograph seamlessly transits, can not bow be made;
2, the utility model reasonably adds a. g. and improves arcing born size, avoids electric field and concentrates and the phenomenon that produces flashover, also extend the service life of section insulator simultaneously;
3, the insulation rod that the utility model uses adopts silicon rubber umbrella skirt parcel high-performance glass fiber rod core, not only can bear large loading, and there is excellent insulating power, corrosion stability and aging resistance, self-cleaning and hydrophobic nature, and do not contact with pantograph;
4, the insulating slide that the utility model uses adopts the body of SMC composite material to form with the support of glass fiber reinforced polyester resin and anchor ear, not only can bear large impact power, and have good resistance to abrasion and electrical insulation properties.
