Product Description

Product Description

HXGN-12 Overview
      HXGN ] -12(SF6) Unit type AC metal-enclosed ring main unit(hereafter refer to as ring net cabinet) is a new generationof high-pressure electric appliance product designed and developed independently by our own company according to therequirement of the domestic agricultural electricity and the city net transformation after introduction of overseas advancedtechnology.

     The cabinet body is riveted after processed by numerical control machine tool with reliable mechanical interlocking andthe misoperating prevention function. The protection grade reaches iP3X.This product has the remarkable characteristics suchas the small volume, light weight, artistic appearance, simple operation, long life, high parameter with no pollution and litlemaintenance.

Specification

HXGN -12 Structural features and working principle

                     The outline structure of the product is referred to as diagram             1 and diagram 2;, the installation dimension is referred toas diagram3. This ring network type cabinet makes air as the insulating medium,mainly assembled with ZFN  -10/630 typevacuum 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 groundingknife conditionally, The three of them are all installed in one machine stand and there are interlocks among them, so thatit 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. 0utgoing cabinet schemeZFN  -10/630 type vacuum load switch, fuse with striker (used as isolating switch) and grounding knife on the main circuitinside the cabinet, and the three working stations oper-ation can be realized. inside the cabinet the components such asCT/PT and ZN0 arrester are available, so the metering 

HXGN -12 Use environmental conditions

1. The altitude should not exceed 2000m.
2.Surrounding airtemperature:-25C~+40°C
3. Relative temperature: the daily average value is not higher than 959, the the monthly average value is nothigher than 90%4. Surrounding air without caustic gas or ignitable gas, steam and other obvious pollution
5.Without fierce vibration
