用途及性能

HXGN系列環(huán)網(wǎng)固定式交流金屬封閉開關(guān)設(shè)備（簡(jiǎn)稱環(huán)網(wǎng)柜）是三相交流額定電壓12KV、額定頻率50HZ的環(huán)網(wǎng)供配電系統(tǒng)和輻射式供配電系統(tǒng)中的開關(guān)成套設(shè)備、作為變壓器、電纜、架空線等電力設(shè)備的保護(hù)、控制之用。其主要開關(guān)元件采用壓氣式負(fù)荷開關(guān)及組合電器和真空負(fù)荷開關(guān)及組合電器。

Application and performance

HXGN series ring fixed AC metal enclosed switchgear (referred to as ring switchgear cabinet) is a complete set of switchgear equipment in the ring power supply and distribution system with rated voltage of 12KV and rated frequency of 50HZ, which is used for protection and control of transformers, cables, overhead lines and other power equipment. The main switching components are pneumatic load switch and combined electrical appliance and vacuum load switch and combined electrical appliance.

結(jié)構(gòu)特點(diǎn)

1、柜體結(jié)構(gòu)為組裝式，穩(wěn)固可靠，組合方便，可構(gòu)成環(huán)網(wǎng)供電單元及各種接線方式。

2、尺寸小，重量輕，占地面積少，便于安裝。

3、環(huán)網(wǎng)柜有母線室、開關(guān)室、儀表隔室三個(gè)安全獨(dú)立分隔區(qū)。柜體及各元件有可靠的安全接地，確保操作和檢修工作者的人身安全。

4、環(huán)網(wǎng)柜可配用FZN21-12D、FZN25-12D等負(fù)荷開關(guān)。

5、機(jī)械聯(lián)鎖先進(jìn)可靠，完全滿足“五防”要求。

Structural characteristics
