Abstract
The invention discloses a new line bridging method and a special bridging line. The special bridging line comprises three bridging units and a special bridge insulating rod, wherein each bridging unit comprises two fixed line clamps which are connected with a line; the bridging line is arranged between the two fixed line clamps; and the special bridge insulating rod is movably connected with the lower ends of the fixed line clamps. The line bridging method and the special bridging line can meet the requirements of bridging of lines of 110KV or less. A device has light weight and high universality, can be conveniently and flexibly operated and is safe to bridge, does not have hidden trouble, and is easy and convenient to transport, assemble and store. Working personnel do not need to work high above the ground. The structure of the bridging device does not have influence on other running equipment and has a broad operating range.
Description
Technical field
The invention belongs to the operation power technical field, relate to 110KV and following defeated, distribution line jumper method and special use and stride on line.
Background technology
In the operation power link, usually can be, or load side has because primary cut-out because of the power equipment mains side, the fault of primary equipments such as high pressure isolation switch, voltage transformer or damage and cause the user to be forced to have a power failure.In this case, tend to because multiple factors such as personnel, spare part, construction environments, can't in time handle faulty equipment, even, perhaps send someone to handle, often need the electricity consumption client is had a power failure for a long time, NQF, so under such a case, be badly in need of designing, by the manipulable emergency wiring jumper of operations staff.
Summary of the invention
The invention provides a kind of program simple, only need to have a power failure in short-term, safe and reliable, need not work high above the ground, labor-saving circuit cross-over connection method and special-purpose jumper.
A kind of new circuit cross-over connection method, it comprises the steps:
A. with the special-purpose jumper of the circuit selected according to electric pressure, application is prepared stand-by;
B. check in the transformer station or two indicated complete display with institute for pipeline equipment outlet phase sequence for unit for circuit mutually;
C. with two mutually for circuit, have a power failure and to do measure;
D. check by for circuit with mutually for phase sequence sign between the circuit phase sequence, install respectively according to B phase, A phase, C phase sequence for the corresponding phase circuit of circuit cross-line with institute respectively and carry out;
E.B phase, A phase, C whenever join cross-line two ends, ground usefulness screw thread screw thread mutually with the wire clamp fixation.
F. check two consistent for circuit mutually with jumper for circuit phase sequence board and phase colored paint.
G. will be mutually remove, send electricity for circuit,, longitudinal difference protection is withdrawed from before sending electricity if institute is equipped with Protectors such as high frequency or optical differential for circuit to institute for both sides' circuit both sides safety measure.
A kind of special-purpose jumper of realizing above-mentioned new circuit cross-over connection method, it comprises that three are crossed over the unit, described each leap unit comprises two fixed line anchor clamps that are connected with circuit, between two fixed line anchor clamps crossover track is set, described special-purpose jumper also comprises crosses over the special isolation bar, and described leap special isolation bar and described fixed line anchor clamps lower end flexibly connect.
Circuit of the present invention connects Vietnamese side's method and special-purpose jumper is striden in special use, can satisfy 110KV and following circuit cross-over connection operation.This installation weight is light, and is flexible to operation, highly versatile, and cross-over connection safety, no hidden danger are transported, assemble, preserve simple and convenient.The staff does not need work high above the ground.The crossover assembly structure can not impact job area to other operational outfit.Owing to cross over particular design and processing that the wire clamp edge of a knife has made to increase contact area, but effectively improve the current capacity of jumper, with mechanical tensile strength, three-phase jumper three is used wrapped with insulation, and scribbling the phase colored paint is distinguished, three-phase is striden suitably control sag of lead-in wire, can not cause electric shock accidents because of the circuit radian.Need not ascend a height before and after the jumper and promptly finish cross-over connection work.Be specially adapted in the station owing to isolating switch, circuit breaker, CT fault, the fault that can't handle in short-term or unusual again, not only can realize the cross-over connection construction operation of not ascending a height, and can reduce leap labour intensity, the user is provided emergency power supply in short-term, has shortened the cross-over connection activity duration greatly, but improved power supply reliability, produce for saving oneself and the back accident treatment that has a power failure for power consumer, won the time.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is described further:
Fig. 1 is that the linked method schematic diagram is striden in special use of the present invention;
Fig. 2 is the structural representation that on line is striden in special use of the present invention.
Embodiment
As shown in Figure 1, a kind of circuit crossing method, it comprises the steps:
A. choose the circuit of leap, and be ready to corresponding circuit and stride the connection instrument;
B. should all be switched on for circuit with quilt for circuit and be done measure;
C. check the on line of striding of not selecting corresponding color after will be by two circuit phase colour code will correct, by installing mutually, insulating rod articulates strides on line mutually for A phase, B phase, C, during installation the wire clamp opening down, the fastening on line folder of striding.
D. check that institute's bridging line both sides phase sequence of adorn is correct, no legacy is striden on line and is pressed from both sides the fastening non-loosening of connection,
A, B, C three spaced apart remain on 80 centimeters distances and the possibility of collision mutually can not take place;
E. remove two line security measures of first, second, recover circuit and send.
A kind of special-purpose jumper of realizing above-mentioned new circuit cross-over connection method, it comprises that three are crossed over the unit, described each leap unit comprises two fixed line anchor clamps 1 that are connected with circuit, between two fixed line anchor clamps 1 crossover track 3 is set, described special-purpose jumper also comprises crosses over special isolation bar 2, and described leap special isolation bar 2 flexibly connects with described fixed line anchor clamps 1 lower end.
The use jumper for circuit can satisfy 110K and following various environment operation, and jumper is simple in structure, and is in light weight, flexible to operation, and highly versatile is crossed over safety, no hidden danger, and transportation, installation are assembled simple and convenient.The operations staff can operate, and need not to overhaul workmen's cooperation, need not work high above the ground and has saved a large amount of time, can reduce the loss of outage that brings because of device damage for the user, but improve the emergent accident disposal ability, be the single supply user, the emergent accident emergency power supply is provided.Because the design of jumper silkworm chrysalis aluminium large contact surface, its electric current through performance is good, in light weight, and after wire clamp compressed, mechanical strength was big.Stride on line and adopt the steel reinforced aluminium conductor of the band phase look japanning of outer insulation jacket parcel, connecting line is taken into account, and sag control has rationally been guaranteed the power supply fail safe behind the band mutually.Circuit is striden connection and need do not ascended a height and promptly finish leap work.Not only can reduce the labour intensity of cross-over connection, shorten greatly and cross over the activity duration, improve leap stringing construction safety coefficient and efficient greatly, reduce personnel and hurried back and forth, improve the emergency disposal ability, enrich the emergency disposal means.
