Power distribution automation cabinet and application thereof

Abstract

The invention discloses a power distribution automation cabinet. The power distribution automation cabinet is composed of a cabinet body and a plurality of unit modules. Each unit module is movably connected with the cabinet body in a pulling-out manner and can be internally arranged in the cabinet body. Each unit module is provided with a plurality of secondary elements with different functions. The power distribution automation cabinet comprises a first power distribution cabinet and a second power distribution cabinet. The first power distribution cabinet is composed of a plurality of single-loop control protection unit modules. The second power distribution cabinet comprises a wiring terminal module, a DTU protection integration unit module, an ONU communication integration unit module and a power supply unit module. The first power distribution cabinet and the power distribution cabinet are electrically connected through the wiring terminal module. Compared with the prior art, the power distribution automation cabinet can be produced as a standard product, all function module equipment of the power distribution automation cabinet can also be produced and designed as standard products, and the power distribution automation cabinet can be matched with any kind of ring network cabinet group for usage; in addition, the safety problems of an outdoor switching station are solved, and the power supply continuity of the outdoor switching station is simultaneously improved.

Description

technical field [0001] The invention relates to a power distribution automation system, more specifically, to a power distribution automation cabinet, which belongs to the technical field of electrical equipment automation. Background technique [0002] The power system includes several main links of power generation, power transmission, power transformation, and power distribution, among which power distribution is a function that directly faces power users. In my country, the situation of "emphasis on power generation, light supply, and no use" has been formed for a long time. The distribution network system is seriously backward, resulting in high loss of residential wires, low voltage, and unreliable power supply, which has become a bottleneck in the power supply and consumption of the power system. In the early stage of power grid construction, more attention was paid to power generation and transmission, while power distribution and power consumption were often underes...

Problems solved by technology

But at present, because the manufacturers of power equipment are different, the equipment produced is also different; but because the national grid standards are now unified, each manufacturer must transform the switchgears that have been put into use in accordance with the national grid standards , that is, to rearrange the wiring of all equipment in the outdoor switching station, which is equivalent to pulling each equipment back to the factory for re-production, which brings certain difficulties to the unification of the national grid standards and does not fundamentally solve the problem of the national grid.
