10kv intelligent high and low voltage prefabricated substation

Abstract

The invention provides a 10kV intelligent high and low voltage prefabricated substation, which includes a high voltage room, an automation room, a transformer room, a low voltage room, a communication room, a concentrator room and a casing. The high voltage room is equipped with a high voltage cabinet, and the high voltage cabinet uses fully sealed gas Insulated 10kV ring network cabinet, the ring-in and ring-out load switches of the ring network cabinet are respectively equipped with electric operating mechanisms and opening and closing position signal auxiliary contacts, and the 10kV line side of the ring network cabinet is equipped with a fault indicator with signal contact output and current The transformer and fault indicator have auxiliary contacts for fault signal output, the position signal of the load switch, the fault signal of the fault indicator and the current signal of the current transformer are output to the automation device; the substation can understand the real-time operation status of the box transformer, and Identify the existence of fault points, and take the faulty substation out of operation in the shortest time, effectively preventing the spread of fault points and other safety accidents.

Description

Technical field [0001] The invention relates to a 10kV intelligent high and low voltage prefabricated substation. Background technique [0002] Existing ordinary high and low voltage prefabricated substations, hereinafter referred to as box substations, when used for community ring network power supply, if one of the box substations in the ring network fails to make a timely judgment, the residents of the community need to find out When the home is out of power and call for repair, the power supply company can go to the site to find the fault point and eliminate the fault point. Early identification and elimination cannot be achieved, which greatly increases the time and cost of repair. The main reason is that the high and low voltage sides of the box change The operating data could not be uploaded, resulting in failure to discover and eliminate in advance. Summary of the invention [0003] The present invention is a 10kV intelligent high and low voltage prefabricated substation,...

AI Technical Summary

Problems solved by technology

[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 is impossible to 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 transformer The running data cannot be uploaded, so it cannot be detected and eliminated in advance
