10 kv intelligent high-and-low-voltage prefabricated substation

Abstract

The invention provides a 10 kV intelligent high-and-low-voltage prefabricated substation which comprises a high-voltage chamber, an automatic chamber, a transformer chamber, a low-voltage chamber, a communication chamber, a concentrator chamber and a housing, wherein a high-voltage cabinet is arranged in the high-voltage chamber and adopts a full-sealed gas insulating 10 kV ring main unit; an electric operating mechanism and a breaking-closing position signal auxiliary contact are respectively mounted on charge switches for ring in and ring out of the ring main unit; a fault indicator with a signal contact output and a current transformer are arranged on the 10 kV line side of the ring main unit; the fault indicator is provided with an auxiliary fault signal output contact; position signals of the charge switches, a fault signal of the fault indicator and a current signal of the current transformer are output to an automatic device. The substation can learn about a real-time operation condition of a box transformer substation so as to judge the existence of a fault point as early as possible and enable a fault box transformer substation to stop operation within the shortest time, so that spreading of the fault point and other safety accidents can be effectively prevented.

Description

technical field [0001] The invention relates to a 10kV intelligent high and low voltage prefabricated substation. Background technique [0002] The existing ordinary high and low voltage prefabricated substations, hereinafter referred to as box transformers, are used for ring network power supply in the community. If a box transformer in the ring network fails to make a timely judgment, it is necessary for residents of the community to find out When there is a power outage at home and a repair call is made, the power supply company can only go to the scene to find the fault point and eliminate the fault point. It cannot make early identification and elimination, which greatly increases the time and cost of maintenance. The main reason is that the high and low voltage side of the box substation The running data cannot be uploaded, so it cannot be detected and eliminated in advance. Contents of the invention [0003] The present invention is a 10kV intelligent high and ...
