更具弹性的电力系统设计方案

您设施的弹性取决于系统架构设计水平。

采用断路器设备的集中式系统设计，可能导致客户侧出现单点故障风险。由于该系统不具备故障隔离能力，任一区域出现问题都可能导致整个园区断电：

Animated gif of a two-story building with a centralized electrical system design. A fault occurs on one of the two electrical lines that are connected to the system’s circuit breaker. The fault causes all the building’s lights to turn off.

One-line diagram of a two-source centralized electrical system. The upper left source, in blue, feeds into a large square, which feeds into four smaller squares, each with a blue arrow descending from it. The upper right source, in orange, feeds into a separate large square and then into four smaller squares with orange arrows descending. In the middle of the line that connects the two large squares is another large square, labeled “N.O.”

但采用Vista开关设备分散部署的分布式系统：

将故障隔离在受影响区域内
通过备用电源重新供电，确保未受影响区域持续运行

Animated gif of the same two-story building used in the centralized design gif. This building has a distributed electrical system design, with six green Vista switchgear boxes distributed around the building’s outside, connected by orange and blue lines. A fault occurs on one of the electrical lines and causes all the building’s lights to turn off momentarily. The distributed system re-energizes the faulted lines using the alternate power source and the building’s lights come back on.

One-line diagram of a two-source centralized electrical system. The upper left source, in blue, feeds into four discrete green rectangles, each with an icon that represents switchgear and each with a blue arrow descending from it. The upper right source, in orange, mirrors this configuration. In the middle of the two sources is text that reads “N.O.”
