Problems solved by technology

Therefore, only by improving the standardization and modularization of equipment can the commonality and interchangeability be improved. However, these manufacturers and the equipment in use have a long history, and cannot achieve high standardization and modularization for a while.
In the prior art, some improvements have been made to the outdoor switchgear and even the distribution automation cabinet: for example, CN202509989 discloses an outdoor switchgear, only a simple structural improvement is made for its door, and the original folding door is changed to a left and right one. Sliding door; as the Chinese patent CN103715616 discloses a ring network cabinet, the overall design of the ring network cabinet is simplified to simplify the internal wiring and reduce the installation workload, and it is not opposite to the inside of the microcomputer protection and control module at the top of the ring network cabinet The structure is improved; for example, Chinese patent CN203367797 discloses an intelligent power distribution automation terminal box, which divides the automation terminal box into a primary room and a secondary room with upper and lower structures, and it is still difficult to confirm the failure of the automation terminal box, resulting in difficulties in maintenance; such as the Chinese patent CN202997354 discloses a distribution network automation ring network cabinet, which includes several ring network cabinets, DTU cabinets and communication cabinets, but the structures in the DTU cabinets and communication cabinets are not improved; as Chinese patent CN103579946 discloses a The distribution network automation integrated ring network cabinet integrates the distribution network automation intelligent terminal and switchgear, but does not improve the structure of the automation intelligent terminal
[0006] To sum up, in the prior art, the improvement of the outdoor switching station, especially the distribution automation cabinet, is nothing more than improving the connection mode of the line, or only improving a certain part for simple structural improvement, which does not reduce the power failure. Fundamentally improved in terms of area and reduced power outage time
[0007] In addition, as the country standardizes the power industry, all power equipment must meet the national grid standards; but at present, because the manufacturers of power equipment are different, the power equipment produced is also different, resulting in With the development of the national grid, the national grid standards have been unified, so all manufacturers must transform the switch stations that have been put into use in accordance with the national grid standards, that is, rearrange the wiring of all equipment in the outdoor switch stations, which is equivalent to The equipment was pulled back to the factory for re-production, which brought certain difficulties to the unification of the national grid standards, and did not fundamentally solve the national grid's transformation requirements for distribution network automation

Embodiment Construction

[0043] The present invention will be described in further detail and completely below in conjunction with the embodiments and accompanying drawings.

[0044] Such as figure 1 As shown, the outdoor switching station is divided into two functional areas, which are composed of several primary equipment areas or incoming and outgoing line areas A and a power distribution automation cabinet 2 (ie secondary equipment area or control area B) and placed in a shell 3 within. The distribution automation cabinet includes a cabinet body and multiple drawer cabinets. The cabinet body and the drawer cabinets are movably connected, and the drawer cabinets are located in the cabinet. There are multiple functional modules on the distribution automation cabinet. Drawer-type assembly is used in the cabinet to form a drawer unit module. The cabinet body and the drawer-type cabinet are preferably plug-in electrical connections. At this time, when a functional module fails, the corresponding drawe...

Abstract

The invention discloses a distribution automation cabinet. The distribution automation cabinet comprises a cabinet body and a plurality of drawer type cabinets, the cabinet body is movably connected with the drawer type cabinets, the drawer type cabinets are positioned in the cabinet body, the distribution automation cabinet is provided with a plurality of function modules, and the function modules are assembled in the distribution automation cabinet in a drawer manner to form drawer unit modules. Compared with the prior art, according to the distribution automation cabinet, the distribution automation cabinet can be produced as standardized products, and the function module devices in the distribution automation cabinet can be produced and designed as standardized products so that the distribution automation cabinet can be employed with the cooperation of any ring main unit provided in the prior art or sold in the market; the problem of the security of the outdoor switching station in the prior art is substantially solved; besides, the power supply continuity of the outdoor switching station can be improved, the development and management of the national smart grid can be facilitated, and the application prospect is very wide.

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...
