Background

At present, a single bus wiring scheme is popularized and used in a transformer substation in a large area, and in the application process, the defects and shortcomings of the single bus wiring scheme are continuously generated. (1) When a section of bus or a bus switch has a fault or needs to be overhauled, the loop of the section of bus has power failure in the overhauling period; (2) when the outgoing line is a double loop, the phenomenon of crossing and spanning of an overhead line often occurs; (3) and during extension, the extension needs to be balanced in two directions.

For the appearance of drawback more than reducing, during the design, be two bus bar cabinets with the high-voltage board design to can effectually avoid the appearance of above-mentioned drawback.

When the double-bus cabinet is used, compared with the connection of the disconnecting switch and the pull rod in the original single bus, when the switch cabinet is changed into the double bus, the position of the disconnecting switch can be correspondingly changed to adapt, and because the position of the disconnecting switch is changed and the operating mechanism is not changed, the length of the pull rod is changed along with the change, but when the existing pull rod is used, the length of the existing pull rod is always fixed, so that a new pull rod is needed to be redesigned to adapt to the double-bus cabinet, and the old pull rod cannot adapt to the double-bus cabinet, so that the existing pull rod cannot be used for replacement when the pull rod is damaged, a new pull rod needs to be remanufactured, when the bus cabinet is manufactured, the bus cabinet cannot be normally used, needs to wait for standby, is not beneficial to the normal use of equipment, and when the positions of the disconnecting switches are different, the lengths of the pull rods are changed, so that various pull rods with different lengths are manufactured according to different mounting positions of the disconnecting switch, a great deal of time and physical effort is also wasted.
