Description
Technical field
The utility model relates to one ± 800kV UHVDC Transmission Lines cage jumper pattern.
Background technology
The wire spacing of strain tower of transmission line mainly by wire span central authorities approach distance and wire jumper determines the gap of iron tower construction member.For extra high voltage direct current transmission line, because wire jumper spacing increases, cause that wire jumper sag increases, and after wire jumper windage yaw, the gap of iron tower construction member is often being determined the wire spacing of shaft tower, and the economic index of shaft tower in final decision.The strain tower wire jumper pattern of therefore economical rationality, safe and reliable, easy construction, can effectively reduce the size of strain tower, reduces project cost, ensures the safe operation of circuit.
What strain tower drainage way use was at present maximum is flexible jumper.Because UHVDC Transmission Lines strain insulator string is longer, adopt flexible jumper drainage distance long, wire jumper sag is larger, therefore needs to lengthen steel tower cross-arm and meets the gap to iron tower construction member after wire jumper windage yaw, and waste steel, improve cost.
Utility model content
The purpose of this utility model is to provide one ± 800kV UHVDC Transmission Lines cage jumper pattern, and the side-play amount can reduce the sag of wire jumper and windage yaw time, can dwindle tower head size, reduces shaft tower height, and saving steel reduces cost.
For achieving the above object, the utility model provides one ± 800kV UHVDC Transmission Lines cage jumper structure, it is characterized in that: flexible jumper one side is connected with strain clamp, opposite side is fixed on cage spider by multiple hood type jumper wire spacing rods, cage spider is connected on steel tower by double V-shaped wire jumper insulator string, cage spider is connected by overhead support bracket with V-type wire jumper insulator string simultaneously, and every side flexible jumper is all installed multiple six bundle jumper spacers, and six conductors is equally spaced.
The utility model flexible jumper one side is connected with strain clamp, opposite side is fixed on cage spider by multiple hood type jumper wire spacing rods, cage spider is connected on steel tower by double V-shaped wire jumper insulator string, side-play amount can reduce the sag of wire jumper and windage yaw time, can dwindle tower head size, reduce shaft tower height, saving steel, reduces cost.Mechanical strength is high, and substantially without amount of deflection, whole system of jumping line does not have field intensity centrostigma, and corona is all right, easy for installation.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is V-type wire jumper insulator string subtended angle structural representation.
Embodiment
With reference to Fig. 1, Fig. 2, flexible jumper 6 one sides are connected with strain clamp 7, opposite side is fixed on cage spider 2 by multiple hood type jumper wire spacing rods 1, cage spider 2 is connected on steel tower by double V-shaped wire jumper insulator string 3, wire jumper V-type string angle is got 90 °, cage spider 2 is connected by overhead support bracket 4 with wire jumper insulator string 3, cage spider 2 is plurality of sections of steel pipes, connect with flange, adjustable-length scope is 12m～16m, on spider, can increase the weight of on demand hammer leaf, every side flexible jumper 6 is all installed 3 six bundle jumper spacers 5, six conductors is equally spaced, heading spacing 450mm.
Whole cage jumper system does not have joint, and transition is more smoothly attractive in appearance, and cage spider mechanical strength is high, substantially without amount of deflection, there is no field intensity centrostigma, and corona is all right, and pattern is succinct, and finished product is attractive in appearance, and construction technology is easily grasped and controlled, and installs more convenient.
