Prefabricated compact intelligent box-type substation

Abstract

The invention discloses a prefabricated compact intelligent box-type substation, which includes a prefabricated steel plate housing, a data acquisition and monitoring control system, and a temperature-sensing self-starting fire extinguishing device. The prefabricated steel plate housing is internally provided with a high-voltage cabinet, a transformer and a low-voltage distribution board in sequence in accordance with a line routing direction; the low-voltage distribution board adopts a fuse-type bar-type disconnector to be hooked on a plugging busbar and is connected with the transformer through a wiring busbar; the high-voltage cabinet adopts an environmental protection gas charging cabinet and is connected with the transformer through a high voltage cable; the temperature-sensing self-starting fire extinguishing device is arranged in the high-voltage cabinet and is in pipeline connection with the transformer and the low-voltage distribution board; and the prefabricated steel plate housing adopts a prefabricated structure, a two-layer box top is adopted, the two-layer box top comprises an upper box top and a lower box top, and the upper box top adopts a push-pull structure. The prefabricated compact intelligent box-type substation has the characteristics of high intelligence level, more compact volume, easy expansion and the like, the operation and the maintenance are convenient, and the power system can be effectively ensured to operate safely.

Description

technical field [0001] The invention relates to the technical field of power system substations, in particular to a prefabricated compact intelligent box-type substation. Background technique [0002] Box-type substation, which replaces the original civil power distribution room and distribution station, has become a more widely used complete set of power transformation and distribution equipment. Users can customize box-type substations according to different conditions of use and load levels, use and put in are more convenient. In recent years, the development of box-type substations is getting faster and faster, with small investment and quick results. Box-type substations can save a variety of expenses such as infrastructure fees for building conventional substation and distribution rooms, and can save a lot of infrastructure investment; box-type substations The substation also has the advantages of simple installation and rapid power supply. When the installation found...

Problems solved by technology

[0004] At present, although the box-type substation in my country has the advantages of smaller size than the traditional civil substation, there are still the following problems: 1) The volume is large, generally requiring an area of ​​10 square meters, and it is difficult to apply to places with small land requirements; 2) Intelligent level Low, mainly due to the operation status of the transformer, which must be checked manually on site, and the situation cannot be fed back in real time. If the transformer station fails, it will not be known for a long time, which will cause greater losses; The type transformer station is generally used outdoors. If it is raining, the operator will repair it in the rain, which will not only affect the health of the operator, but also cause safety accidents easily when operating in the rain.
