HXGN □ -12(SF6) Unit type AC metal-enclosed ring main unit(hereafter refer to as ring net cabinet) is a new generation of high-pressure electric appliance product designed and developed independently by our own company according to the requirement of the domestic agricultural electricity and the city net transformation after introduction of overseas advanced technology. Each technical performance index completely reaches the IEC298 and GB3906 standard.

The loop-net cabinet s main switch, the operating mechanism and the components is made of the ABB Corporation original piece or the SFL-12/24 switch equipment imported overseas and assembled at home. We can also install the ABB Corporation original piece of HAD/US type SF according to the request of users. The circuit breaker or the VD4-Svacuum circuit-breaker divide into two kinds: be operated manually and electrically according to the operating mode.

The cabinet body is riveted after processed by numerical control machine tool with reliable mechanical interlocking and the misoperating prevention function. The protection grade reaches IP3X.This product has the remarkable characteristics such as the small volume, light weight, artistic appearance, simple operation, long life, high parameter with no pollution and little maintenance.

HXGN□-12箱型固定式金屬封閉開關(guān)設(shè)備結(jié)構(gòu)特點及工作原理  Structural Characteristics and Working Principle

產(chǎn)品外形結(jié)構(gòu)見圖1、圖2，安裝尺寸如圖3所示。本環(huán)網(wǎng)柜是以空氣為絕緣介質(zhì)的，主要配裝ZFN□-10/630型真空負荷開關(guān)，主要方案有進線柜和出線柜等。

1. 進線柜方案

柜內(nèi)主回路有一臺ZFN□ -10/630 型真空負荷開關(guān)，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(lián)鎖。因此可實現(xiàn)接通母線、隔離、接地三個工位的操作，柜內(nèi)還可靈活配裝CT、PT等元件。

2. 出線柜方案

柜內(nèi)主回路有一臺ZFN□-10/630型真空負荷開關(guān)和帶撞擊器的熔斷器(有隔離開關(guān)的作用)及接地刀所組成，也可實現(xiàn)三工位操作，柜內(nèi)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(guān)聯(lián)鎖的絕緣防護隔板，柜內(nèi)各開關(guān)與隔板及柜門間采用機械聯(lián)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 components 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 operation 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 outgoing 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.
