 产品外形结构见图 1、图 2，安装尺寸如图 3 所示。本环网柜是以空气为绝缘介质的，主要配装 ZFN □ -10/630 型真空负荷开关，主要方案有进线柜和出线柜等。 

1. 进线柜方案 

柜内主回路有一台 ZFN □ -10/630 型真空负荷开关，它配装有隔离刀、酌情还配装接地刀所组成，三者共装在一个机架上，并互有联锁。因此可实现 接通母线、隔离、接地三个工位的操作，柜内还可灵活配装 CT、PT 等元件。 

2. 出线柜方案

柜内主回路有一台 ZFN □ -10/630 型真空负荷开关和带撞击器的熔断器 ( 有隔离开关的作用 ) 及接地刀所组成，也可实现三工位操作，柜内还可灵活 配装 CT/PT 和 ZNO 避雷器等元件，因此有时可省去计量柜。进、出线柜均配有与接地开关联锁的绝缘防护隔板，柜内各开关与隔板及柜门间采用机械 联锁，并达到“五防”要求，柜体外壳防护等级为 IP2X。

The outline structure of the product is referred to as diagram 1 and diagram 2; the installation dimension is referred to as diagram3. This ring network type cabinet makes air as the insulating medium,mainly assembled with ZFN □ -10/630 type vacuum load switch. And there are two cabinet schemes - incoming cabinet and outgoing cabinet. 

1.Incoming cabinet scheme

   There is a ZFN □ -10/630 type vacuum load switch on the main circuit inside the cabinet with isolating knife, and grounding knife conditionally. The three of them are all installed in one machine stand and there are interlocks among them, so that it is realized to connect the operation of three working stations of bus, isolation and grounding. Inside the cabinet the com-ponents such as CT, PY are available.

2.Outgoing cabinet scheme

   ZFN □ -10/630 type vacuum load switch, fuse with striker (used as isolating switch) and grounding knife on the main circuit inside the cabinet, and the three working stations oper-ation can be realized. Inside the cabinet the components such as CT/PT and ZNO arrester are available, so the metering cabinet can be omitted. Inside the incoming cabinet and out-going cabinet, there is insulating protecting baffle interlocked with grounding switch. And inside the cabinets ,the mechanical interlocks are adopted between each switch and baffle as well as the cabinet door with the requirement of “five-prevention” and IP2X of the protection degree of the cabinet enclosure.
