結構特點及工作原理   Structural features and working principle

 產品外形結構見圖 1、圖 2，安裝尺寸如圖 3 所示。本環網柜是以空氣為絕緣介質的，主要配裝 ZFN □ -10/630 型真空負荷開關，主要方案有進線柜和出線柜等。 

1. 進線柜方案 

柜內主回路有一臺 ZFN □ -10/630 型真空負荷開關，它配裝有隔離刀、酌情還配裝接地刀所組成，三者共裝在一個機架上，并互有聯鎖。因此可實現 接通母線、隔離、接地三個工位的操作，柜內還可靈活配裝 CT、PT 等元件。 

2. 出線柜方案

柜內主回路有一臺 ZFN □ -10/630 型真空負荷開關和帶撞擊器的熔斷器 ( 有隔離開關的作用 ) 及接地刀所組成，也可實現三工位操作，柜內還可靈活 配裝 CT/PT 和 ZNO 避雷器等元件，因此有時可省去計量柜。進、出線柜均配有與接地開關聯鎖的絕緣防護隔板，柜內各開關與隔板及柜門間采用機械 聯鎖，并達到“五防”要求，柜體外殼防護等級為 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.

吊運、安裝、調試和熔斷器的更換  Lifting, installation, commissioning and replacement of fuses

1. 吊運

3. 調試 

    如發現柜內元件達不到其技術要求或聯鎖不到位時，需按下列過程調試： (1) 對負荷開關和接地或隔離開關，可通過調節拉桿長度和變換拉桿與操作桿角度和位置來達到技術要求。 (2) 若有聯鎖不到位時，可微調相應的操作拉桿長度來改變聯鎖孔的位置，使聯鎖到位。 

4. 更換熔斷器 

    必須嚴格按停電順序操作，將負荷開關分閘，然后打開熔斷器到隔離位置，并將接地開關合上，在插入絕緣防護隔板后，柜門方可打開，才能進 行更換熔斷器。

1. Handling 

    Before handling, undertake check before opening the cabinet according to the regulations. When thecabinet is handling delivered, it's a must to operate according to the operation marking demands.Handle with care and without shake.

2. Installing 

    After opening the cabinet, check whether the cabinet body and the components inside are good,whether they work normally, and whether they are moistened. Only after definite confirmation can the installation be undertaken. 

3. Debugging

    It's necessary to have a debugging according to the following steps if the components inside thecabinet don't meet the technical requirements or the interlocks don't locate well: (1) For the load switch, grounding switch or isolating switch, you can make them meet the technical demands by adjusting the drag rod length, changing the angle and position of drag rod and operating rod. (2) If there is any interlock that doesn't locate well, you can make it locate by fine adjusting relevant operating rod length to change the position of interlock hole.

4. Fuse replacing 

    It must operate strictly according to the sequence of power off. First, turn off the load switch, turn on the fuse to the isolating position and then turn on the grounding switch. Only after plugging the insulating protecting baffle can the cabinet door be opened and can the fuse be replaced.
