Description

technical field [0001] The invention relates to a substation, in particular to an intelligent box-type substation. Background technique [0002] In the urban construction in recent years, combined and pre-installed box-type substations have been widely used in order to meet the needs of high-rise building electricity users and not affect the city's appearance. However, most of these power distribution equipment adopt traditional combination methods, coupled with backward equipment technology, low degree of automation, and high equipment damage rate, which directly affects the normal electricity consumption of power users. In the actual power supply process, the traditional box-type substation does not use high-efficiency energy-saving transformers, no automatic on-load voltage regulation and capacity regulation devices, the quality of power supply is poor, and the loss of the transformer itself is large, and the traditional distribution transformer and high-voltage metering ...

Problems solved by technology

However, due to the traditional combination of these power distribution equipment, coupled with backward equipment technology, low degree of automation, and high equipment damage rate, it directly affects the normal power consumption of power users.

In the actual power supply process, the traditional box-type substation does not use high-efficiency energy-saving transformers, no automatic on-load voltage regulation and capacity regulation devices, the quality of power supply is poor, and the loss of the transformer itself is large, and the traditional distribution transformer and high-voltage metering device 2 The voltage and current transformers and circuit breakers used mostly adopt the oil-immersed insulation method. Once an electrical fire occurs, it is not conducive to fire protection; in the traditional box-type substation power supply mode, there is generally only one 10KV power supply on the high-voltage side. When the 10K power supply fails In the end, it will inevitably cause power outages in high-rise buildings or residential areas, and the reliability of power supply is very low. Moreover, the traditional box-type substation lacks communication equipment such as monitoring and management. Difference
