Embodiment Construction

[0034] The following will describe in detail the implementation of the ring grid sub-area power supply system and method of the present invention with reference to the accompanying drawings.

[0035] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network. It includes three units of power transformation, power transmission and power distribution. The task of the power grid is to transmit and distribute electrical energy and to change the voltage.

[0036] Among the transmission and distribution voltage levels, 6, 10, 20, 35, and 66 kV are medium voltage, 110, 220 kV are high voltage, 330, 500, and 750 kV are ultra-high voltage, DC 800, AC 1000 kV and above for UHV.

[0037] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly. The operating voltage level of the power grid system has continued to increase, and ...

Abstract

The present invention relates to a power supply system for subregions of a ring power grid, comprising: a ring power grid mechanism, which is composed of a plurality of power grid structures connected end to end, and is arranged on a rectangular wall surrounding a rectangular working area of ​​a prison. The rectangular working area is composed of a plurality of working sub-areas The area of ​​each labor sub-area is equal, and the number of each power grid structure is the same as the number of the work sub-area it surrounds; the power grid control switch is used to electrify the power grid structure corresponding to each target number received, and is also used to De-energize grid structures corresponding to numbers that are not part of the target number. The invention also relates to a regional power supply method of the ring power grid. The regional power supply system and method of the ring power grid of the present invention are compact in design and intelligent in operation. Because it can provide high-voltage power supply to the area where only the human body exists in the prisoner's workplace, the intelligent level of power supply control can be improved.

Description

technical field [0001] The invention relates to the field of electric power supply, in particular to a ring power grid sub-area power supply system and method. Background technique [0002] Power supply refers to the safe, reliable, continuous and qualified sale of electric energy to the majority of power customers through power transmission and distribution devices, so as to meet the needs of customers for economic construction and domestic power consumption. Power supply organizations include power supply bureaus and power supply companies. [0003] Electric energy is the main energy and driving force of modern industrial production. It is easy to convert from other forms of energy, and easy to convert into other forms of energy for use; its transportation and distribution are simple and economical, and it is easy to control, adjust and measure, which is conducive to the automation of the production process. Therefore, electric energy is widely used in modern industry an...
