Description

Safe and reliable's vertical transformer substation

Technical Field

The utility model belongs to the technical field of the transformer substation technique and specifically relates to a safe and reliable's vertical transformer substation.

Background

The prefabricated transformer substation is a brand-new transformer substation rising up after civil engineering transformer substations, and is characterized in that the prefabricated indoor and outdoor compact distribution equipment is manufactured by factories which are integrated according to a certain wiring scheme, namely, the functions of transformer voltage reduction, low-voltage distribution and the like are organically combined together and installed in a moistureproof, antirust, dustproof, rat-proof, fireproof, antitheft and movable steel structure box. The prefabricated substation is suitable for mines, factory enterprises, oil-gas fields and wind power stations, replaces the original civil power distribution room and power distribution station, and becomes a novel complete set of power transformation and distribution device.

The prefabricated substation in the prior art is mostly a whole cabinet, and has the horizontal type, also has the vertical type, and horizontal box transformer substation is that the transformer is placed with function module parallel, and vertical substation is that the transformer is placed on the upper strata of cabinet, and the function module is placed in the lower floor of cabinet, however, whether horizontal or vertical all places transformer and function module inside the cabinet, and this has just brought the inconvenience for installation and transportation, is unfavorable for the heat dissipation of transformer moreover. Therefore, the industry has improved, for example, the vertical transformer substation disclosed by the Chinese patent has the following patent numbers: 201821830951.1, including the switch board with set up in the transformer of switch board roof top, be provided with a plurality of independent accommodation spaces in the switch board, the accommodation space is used for placing functional module for the distribution, on the switch board in each accommodation space department still be provided with one with the door plant of switch board pin joint, each the door plant is used for opening/closing the corresponding accommodation space. The cable-insulated power distribution cabinet is characterized in that a cable hole for a cable to enter the power distribution cabinet is formed in the top wall of the power distribution cabinet, and an insulating sleeve is arranged in the cable hole, so that the cable and the top wall of the power distribution cabinet are in an electric insulation state. Still the cover is equipped with a protection casing on the transformer, the protection casing is one end open-ended tubular structure, the lower extreme opening part of protection casing with the roof butt joint of switch board. The side wall of the protective cover is provided with a ventilation opening in a shutter structure, and the ventilation openings on the opposite side walls of the protective cover are arranged oppositely. And a gauze is further covered on the inner side wall of the protective cover at the vent. The protective cover comprises a base and a top, the base is in butt joint with the top wall of the power distribution cabinet, the height of the base is equivalent to that of the transformer, the top is located above the base, and the top is of a tip structure which is gradually narrowed from bottom to top.
