Abstract

The utility model belongs to high-voltage power transmission and distribution devices, and relates to a busbar connection structure between switch cabinets, which comprises an original switch cabinet, an added switch cabinet and a transition cabinet, wherein the original cabinet and the added switch cabinet are arranged in parallel; the transition cabinet is disposed between the top of the original switch cabinet and the top of the added switch cabinet; a vertical three-phase original switch cabinet busbar and a vertical three-phase added switch cabinet busbar are respectively led out from the top of the original switch cabinet and the top of the added switch cabinet and extend into the transition cabinet; the upper end of the three-phase original switch cabinet busbar is connected with the upper end of the three-phase added switch cabinet busbar respectively through three-phase horizontal transition busbars; the three-phase original switch cabinet busbar keeps a certain insulation distance with the three-phase added switch cabinet busbar in the cabinet width direction and the cabinet depth direction; and each of the three-phase horizontal transition busbars keeps a certain insulation distance with each other in the height direction. When the busbar connection structure between switch cabinets is applied to extension and modification of substations, manufacturers of added switch cabinets do not need power interruption measurement, and power-off time in construction process can be reduced.

Description

Bus connection structure between switch cubicle

Technical field

The utility model belongs to the high pressure equipment for power transmission and distribution, relates to a kind ofly in transformer station's extending capacity reformation process, is used for bus connection structure between original switch cubicle and switch cubicle that the bus of newly-increased switch cubicle is connected.

Background technology

In the extension project of transformer station, the manufacturer of the newly-increased switch cubicles of great majority is different with former switch cubicle manufacturer.Because it is relatively more difficult to seek the inner structure size of former producer switch cubicle, generally in the design phase, new switch cubicle manufacturer can require on-the-spot the power failure, the bus-bar room of taking switch cubicle apart is checked the spread pattern of three-phase bus, is measured the bus position dimension, so that newly-increased switch cubicle docks with the direct of former switch cubicle bus, because the in-site measurement bus needs substation busbars to have a power failure, and electric power system is very strict for the examination of reliability and the management that has a power failure, so each extention project all can be met difficulty on the measurement bus problem that has a power failure.

Summary of the invention

Technical problem to be solved in the utility model is, provide a kind of can the enlarging in the transformation process that the bus that increases switch cubicle and original switch cubicle newly is connected in transformer station, and need not have a power failure to measure, can reduce bus connection structure between the switch cubicle of interruption duration that bus connects operation process simultaneously.

Bus connection structure includes original switch cubicle and the newly-increased switch cubicle of settling side by side between switch cubicle of the present utility model, is provided with a transition cabinet between the top of original switch cubicle and newly-increased switch cubicle; Draw former switch cubicle bus of vertical three-phase and the newly-increased switch cubicle bus of three-phase respectively by former switch cubicle top and newly-increased switch cubicle top, the newly-increased switch cubicle bus of former switch cubicle bus of three-phase and three-phase all stretches in the transition cabinet, and the former switch cubicle bus of three-phase upper end interconnects by the transition bus of three-phase level respectively with the newly-increased switch cubicle bus of three-phase upper end; The newly-increased switch cubicle bus of former switch cubicle bus of described three-phase and three-phase all has certain insulation distance on cabinet Width and depth direction, simultaneously three-phase transition bus on short transverse also at a distance of certain insulation distance.

When structure applications of the present utility model is transformed in transformer station's enlarging, the manufacturer of newly-increased switch cubicle can arrange bus according to the product of oneself, the former switch cubicle bus size of measurement no longer needs to have a power failure, when construction, can finish the overlap joint of early stage and current period bus the shortest time, reduce the interruption duration of work progress.

Embodiment

As shown in the figure, bus connection structure includes original switch cubicle 1 and the newly-increased switch cubicle of settling side by side 2 between this switch cubicle, is provided with a transition cabinet 3 between the top of original switch cubicle and newly-increased switch cubicle; Draw former switch cubicle bus 4 of vertical three-phase and the newly-increased switch cubicle bus 5 of three-phase respectively by former switch cubicle top and newly-increased switch cubicle top, the newly-increased switch cubicle bus of former switch cubicle bus of three-phase and three-phase all stretches in the transition cabinet 3, and newly-increased switch cubicle bus 5 upper ends of three-phase former switch cubicle bus 4 upper ends and three-phase interconnect by the transition bus 6 of three-phase level respectively; The newly-increased switch cubicle bus of former switch cubicle bus of described three-phase and three-phase all has certain insulation distance on cabinet Width and depth direction, simultaneously three-phase transition bus 6 on short transverse also at a distance of certain insulation distance.

Claims
