摘要:
环网柜是一组高压开关设备装在钢板金属柜体内或做成拼装间隔式环网供电单元的电气设备，其核心部分采用负荷开关和熔断器，具有结构简单、体积小、价格低、可提高供电参数和性能以及供电安全等优点。因此，它被广泛使用于城市住宅小区、高层建筑、大型公共建筑、工厂企业等负荷中心的配电站以及箱式变电站中。随着国内城市电网建设与改造的加快，高压进入市区，直接深入负荷中心，环网供电成为解决城市负荷密度增加而呈现的必然结果。本次设计的内容是根据已有的10KV充气环网柜的样机及其说明书，对其进行测绘重构与动作分析。
环网柜属二次配电设备。二次配电设备是指将高压变压器受电的一次配电设备的电能进行再分配的中压开关设备。二次配电设备基础元件为负荷开关和限流熔断器，不但经济，而且保护特性好（如限流熔断器保护变压器）。我国传统二次配电设备是用断路器，不但价格贵，保护性也不好。此次设计的主要目的是以已有的参考资料为依据，对环网柜样机的组成零件进行测绘重构,三维建模并进行精度设计从而改进其工艺，进一步完善其性能。
本次设计内容主要包括样机零件的测绘重构，精度设计以及工艺改进。对样机进行有序的拆卸并记录,对每个零件进行测绘以及三维建模。由于样机大多数零件为钣金件,其加工多采用激光切割，所以我们针对若干典型零件进行精度设计。改进零件的加工工艺使其在功能不变的情况下结构更加简单，操作更加方便，保护性更加稳定，成本更加低廉。

PROE software based 10kV gas-insulated RMU mapping reconstruction

Abstract：
RMU is a group of high-voltage switchgear cabinet mounted on a metal plate made of assembled or interval-type ring network power supply unit of electrical equipment, the core of the use of load switch and fuse, has a simple structure, small size, low price, can be improve power supply and power supply safety parameters and performance advantages. Therefore, it is widely used in power distribution stations, and box-type substation urban residential areas, high-rise buildings, large public buildings, factories and enterprises, such as load centers. With the acceleration of domestic urban power grid construction and transformation of high pressure into the city, directly load center, ring network load power becomes resolved to increase urban density and showed the inevitable result. The design is based on the contents of the existing 10KV RMU inflatable prototype and specification, its mapping reconstruction and motion analysis.
RMU is a secondary distribution equipment. Secondary power distribution equipment refers to the power of a high-voltage transformer and distribution equipment redistribution of medium voltage switchgear. Basic components of the secondary power distribution equipment load switch and current-limiting fuses, not only economic, but also protect the characteristics of a good (such as limiting fuses protect the transformer). China's traditional breaker secondary distribution equipment is not only expensive, protection is not good. The main purpose of this design is based on the existing reference as a basis for RMU prototype parts for mapping the composition of the reconstruction, 3D modeling and design to improve the accuracy of its technology, to further improve its performance.
This design mainly includes mapping reconstructed prototype parts, precision design and process improvements. Ordered the demolition of the prototype and records, conduct mapping and three-dimensional modeling of each part. Since most parts of prototype sheet metal parts, the processing of multi-use laser cutting, so we designed for a number of typical precision parts. Improved processing technology to make parts in the function unchanged structure more simple, more convenient, more stable protection, cost more affordable.
