Outdoor Shed

Abstract

The present invention discloses an outdoor switching station, comprising a ring main unit group, distribution automation cabinets and a housing, wherein the ring main unit group and the distribution automation cabinets are arranged in the housing, the distribution automation cabinets are arranged at the same side of the ring main unit group, the distribution automation cabinets are provided with a plurality of function modules, and each function module forms a drawer unit module in the distribution automation cabinet by being assembled in the form of drawer. Compared with the prior art, the outdoor switching station provided by the present invention can effectively solve a safety problem existing in an outdoor switching station in the prior art, and simultaneously can improve power supply continuity of the outdoor switching station, in addition, the outdoor switching station can be produced as a standardized product, and the function modules in the outdoor switching station also can be produced and designed as standardized products, thus development and management of a smart power grid of our country can be facilitated, therefore, the application prospect of the outdoor switching station of present invention is very wide.

Description

technical field [0001] The invention relates to a power distribution automation system, and more specifically relates to an outdoor switching station, 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

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.

Some improvements have been made to the outdoor opening and closing station in the prior art: for example, CN 202509989 discloses an outdoor opening and closing station, only a simple structural improvement is made on the door, and the original folding door is changed to a left and right sliding door; Chinese patent CN103715616 discloses a ring network cabinet, which simplifies the overall design of the ring network cabinet to simplify the internal wiring and reduce the installation workload, and does not improve the internal structure of the microcomputer protection and control module placed on the top of the ring network cabinet; For example, Chinese patent CN203367797 discloses a kind of intelligent power distribution automation terminal box. The automation terminal box is divided into a primary room and a secondary room. 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 have not been improved; as Chinese patent CN103579946 discloses a distribution network automation integrated The ring network cabinet integrates the distribution network automation intelligent terminal and switchgear, but does not improve the structure of the automation intelligent terminal

[0007] To sum up, the improvement of the outdoor switching station in the prior art is nothing more than improving the connection mode of the line, or only improving a certain part for simple structural improvement, and does not reduce the power failure area and reduce the power failure time. fundamental improvement

[0008] 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
