Distribution automation cabinet and application thereof

Abstract

The invention discloses a distribution automation cabinet, which comprises a cabinet body and a plurality of unit modules, wherein each unit module is movably connected to the cabinet body in a drawing-out mode and can be arranged in the cabinet body, and each unit module is provided with a plurality of secondary elements with different functions; the distribution automation cabinet comprises a first power distribution cabinet and a second power distribution cabinet, the first power distribution cabinet is formed by a plurality of single-loop control protection unit modules, and the second power distribution cabinet comprises a wiring terminal module, a DTU protection comprehensive unit module, an ONU communication comprehensive unit module and a power supply unit module, wherein the firstpower distribution cabinet and the second power distribution cabinet are electrically connected through the wiring terminal module. Compared with the prior art, the distribution automation cabinet provided by the invention can be used as a standard product for production, each functional module device of the distribution automation cabinet can also be used as a standardized product for productiondesign, and the distribution automation cabinet can be matched with any ring network cabinet group for use; the safety problem existing in outdoor opening and closing is solved, and the power supplycontinuity of outdoor opening and closing is improved.

Description

[0001] This case is a divisional application of application number 2014106977354. technical field [0002] 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 [0003] 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...

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.
