Abstract
The utility model relates to an American box-type transformer substation, which comprises a transformer, a high-voltage chamber and a low-voltage chamber, and is characterized in that a load switch cabinet is arranged in the high-voltage chamber at the front side of the transformer, and consists of a cabinet body, a load switch of the transformer substation, a disconnecting switch, a grounding switch and a fuse; the cabinet body is fixed on a bottom plate of the high-voltage chamber; an incoming line cable is introduced into the load switch cabinet from the lower part of the high-voltage chamber and is connected with the load switch; after the load switch is connected with the disconnecting switch and the fuse, a connecting line penetrates through a high-voltage cabinet and is connected with the transformer, so that the high-voltage load switch can be conveniently disconnected and a power supply is cut off; the maintenance is easy, and the grid operation is very convenient and safe.
Description
Technical field
The utility model relates to a kind of transformer station, particularly relates to the box-type substation that a kind of American box-type substation high-pressure side is provided with loading switch cabinet.
Background technology
The structure of present American box-type substation is shown in Fig. 1～3: it comprises transformer, hyperbaric chamber, low-pressure chamber, the Chinese character pin-shaped layout of three, be divided into forward and backward two parts, the front is the high and low pressure cabinet, the rear portion is an oil tank of transformer, high voltage load switch is installed in oil tank of transformer 3 inside, and cable directly inserts transformer after entering the box-type substation station.Its weak point is: (1) is difficult to outlet and is incorporated into the power networks: because transformer station when outlet is incorporated into the power networks, can't connect the outlet cable joint; (2) inconvenient maintenance: keep in repair transformer and inner components and parts thereof if desired, must after the upper level switchyard disconnects the upper level switch, just can keep in repair; (3) maintenance is dangerous: the scene does not have visual fracture, must prevent misdelivery.
The utility model content
The purpose of this utility model provides a kind of American box-type substation that keeps in repair safe ready.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of American box-type substation, comprise transformer, high and low pressure chamber, it is characterized in that: loading switch cabinet is arranged in the hyperbaric chamber of transformer front side, it is made up of on-load switch, isolating switch, earthed switch, the fuse of cabinet, transformer station, cabinet is fixed on the base plate in hyperbaric chamber, the inlet wire cable is introduced the loading switch cabinet from the bottom, hyperbaric chamber, and be connected with on-load switch, after on-load switch connected isolating switch and fuse again, line passed high-voltage board and is connected with transformer.
The utility model can also be provided with cable joint in described loading switch cabinet, the outlet of fuse is connected with transformer by cable joint, perhaps adds bus row again and connect with the cable that conveniently is incorporated into the power networks before cable joint.
On-load switch described in the utility model can adopt three station SF6 on-load switches of isolation, earthing position, and it is positioned at the top of cabinet, thereunder connects fuse, and the below of fuse is provided with cable joint.Can be divided into branch, combined floodgate switch, divide, the combined floodgate switch can be manual, also can be electronic.
The utility model can install a ring main unit additional, connects ring main unit by the outlet of loading switch cabinet place, and the outlet of realization transformer station is incorporated into the power networks.
The beneficial effects of the utility model are: (1) cabinet is installed in oil tank of transformer outside, can be easily disjunction high voltage load switch on the spot, cut off the electricity supply, easily maintenance; (2) there is visual fracture at the scene, and being incorporated into the power networks, operation is very easy, safety; (3) loading switch cabinet can be installed very convenient with bolt or welded and installed on base; (4) divide, the combined floodgate switch can manual or electronic control, and is safe and reliable.
