  一、產品特點 Product features

1. 斷路器功能復合，安全可靠 Circuit breaker is safe and reliable with composite functions

主開關ZN118縱旋隔離真空斷路器是集真空斷路器、隔離開關及連鎖機構于一體的功能復合斷路器，它將開斷、隔離、連鎖三大功能有機集成為一體，既具有斷路器功能，還具有隔離開關功能，操作簡單，安全可靠。

ZN118 longitudinal rotation isolating vacuum circuit breaker, as the main switch-gear, is a composite electrical equipment with multiple functions integrated by vacuum circuit, disconnecting switch and interlocking mechanism, having the characteristics of easy operation and reliable properties.

2. 簡單可靠的主回路，利于散熱 Main circuit is reliable and simple with effective heat dissipation

主回路由縱向水平布置的匯流主母線，縱旋隔離真空斷路器、電流互感器、接地開關及電纜頭等元件組成，從上至下垂直互聯(lián)，元件之間無過渡支母線及其支撐件連接，導電路徑短，功率損失小，氣流通道上下貫通，加速熱量散發(fā)，降低了溫升。

Main circuit consists of bus master with longitudinally horizontal arrangement, longitudinal rotation isolating vacuum circuit breaker, current transformer, grounding switch, cable head and other components. The components connected each other longitudinally without transition branch bus and supporting elements, but with short conductive path , low power loss, clear air passage that can fasten the heating dissipation and lower the temperature rise.

3. 明顯可見的隔離窗口 Visible isolation window

縱旋隔離真空斷路器手車從工作位置到試驗位置（隔離位置），無需移動手車，可手動和電動操作，操作者可通過柜前面板上的觀察窗，直接看到動觸頭與靜觸頭咬合和隔離動作的全過程，使操作者的安全更有保障。

The handcart of longitudinal rotation isolating vacuum circuit breaker can shift from working position to testing position(disconnecting position) without moving it. It can be operated by hand or electric. The whole process of connection and disconnection between moving contact and static contact can be observed by users from the sightglass on the front panel,which can guarantee the safety of the users.

4. 小型化柜型設計的典范 Classic design of miniaturized cabinet

主要配套元件都進行了功能復合化設計和相應的優(yōu)化設計，額定電流1250A 及以下的柜寬做到650mm，額定電流1600-2500A的柜寬做到850mm，額定電流3150A（自然風冷）、4000A（強制風冷）的柜寬做到1000mm，開關設備既可靠墻安裝，又可雙面安裝，是同類空氣開關設備小型化的典范。主回路所有的空氣絕緣距離均大于125mm。

Main supporting components are developed the design of composite function and other optimization designs by our technical section. The cabinet with 1250A or below current can be made 650mm in width, the 1600-2500A can be made 850mm , the 3150A(natural ventilation) and the 4000A (forced ventilation) can be made 1000mm. The switch-gears, becoming the model of miniaturized air switching equipment, apply to wall arrangement or double-sided installation.

5. 更具智能化 More intelligent

 可遠程電動操作縱旋隔離真空斷路器、接地開關，方便故障線路快速隔離，非故障線路快速恢復，實時在線溫升監(jiān)測、機械特性監(jiān)測、狀態(tài)監(jiān)測、局放監(jiān)測、遠程計算機監(jiān)控、手機APP監(jiān)控功能，滿足無人值守變電站和智能電網的要求。

Longitudinal isolation vacuum circuit breaker and grounding switch can be remotely operated by electricity, which will quickly disconnect the fault circuit and restore the non-fault circuit. It also can conduct a series of detection of temperature rise ,mechanical properties , machine’s condition and partial discharge under the monitoring via computer and APP in phone , which meets the demands of unattended substation and intelligent power network.
