              中高壓微型斷路器有什么特性?

              中壓斷路器:中壓路斷路器額定電壓在0-7.2KV之間,可使用1組裝成金屬制成品室內封閉開關設備線,也可以在室外安裝組件個別變電站??諝鈹嗦菲魅〈蚱茊挝坏氖覂葢贸溆?,但現在已取代了真空斷路器(約35千伏)。像高壓斷路器那樣,這也是保護電流感應繼電器通過操作電流互感器。中壓斷路器的特點都是通過國際標準,如IEC 62271。中壓斷路器幾乎總是使用不同的傳感器和電流保護繼電器,而不是依靠內置的熱過電流或磁場傳感器。

              Medium voltage circuit breaker: the rated voltage of the medium voltage circuit breaker is between 0-7.2kv. It can be assembled into a metal finished indoor closed switchgear line by 1, and individual substations can also be installed outdoors. The air circuit breaker replaces the indoor application oil filling of the breaking unit, but now it has replaced the vacuum circuit breaker (about 35 kV). Like the high-voltage circuit breaker, it also protects the current sensing relay by operating the current transformer. The characteristics of medium voltage circuit breakers are through international standards, such as IEC 62271. Medium voltage circuit breakers almost always use different sensors and current protection relays instead of relying on built-in thermal overcurrent or magnetic field sensors.
              中壓斷路器,按撲滅電弧的介質可分為:
              Medium voltage circuit breaker can be divided into:
              真空斷路器,額定電流至3000A,這些斷路器電流中斷的容器創建和真空電弧熄滅的研究。這是普遍適用的電壓高達約35,000A, 對應的范圍大致電力系統中電壓。 真空斷路器之間往往有預期壽命比較大的空氣斷路器。
              Vacuum circuit breakers, rated current up to 3000A, these circuit breakers create containers with current interruption and study the extinction of vacuum arc. This is generally applicable to voltages up to about 35000a, corresponding to roughly the range of voltages in the power system. There are often air circuit breakers with long life expectancy between vacuum circuit breakers.
              空氣斷路器,額定電流至10,000A,特征往往是完全可調行程包括可配置的閾值和延誤。通常通過電子控制,雖然有些型號的微處理器控制單元通過一個完整的電子流程。 通常用于易于維護的地方,主要分布在大型工業廠房。
              Air circuit breakers, rated to 10000 a, are often characterized by fully adjustable travel, including configurable thresholds and delays. Usually through electronic control, although some models of microprocessor control units through a complete electronic process. It is usually used in places easy to maintain, mainly distributed in large industrial plants.
              六氟化硫斷路器氣體滅火用硫磺充滿弧一室。
              Sulfur hexafluoride circuit breaker gas fire extinguishing fills the arc chamber with sulfur.
              中壓斷路器,可連接到電路由螺栓連接母線或電線,尤其是在戶外。在開關線制成品中壓斷路器在構建時常常抽出建設,使斷路器被刪除,而不會干擾主電路連接,采用電動操作或手搖機制,以脫離其外殼斷路器。
              Medium voltage circuit breakers can be connected to the circuit by bolted bus bars or wires, especially outdoors. During the construction of the medium voltage circuit breaker of the finished switch line, the construction is often pulled out, so that the circuit breaker can be deleted without disturbing the connection of the main circuit. The electric operation or manual mechanism is adopted to separate the circuit breaker from its shell.
              高壓斷路器:電氣輸電網絡得到定義高電壓不一,但在動力傳輸工作通常被認為是72.5KV或更高,根據最近的定義由一個國際電工委員會(IEC)的。 高壓斷路器的人幾乎都是電磁式,與電流感應保護繼電器通過操作變電站的繼電保護計劃可能會很復雜,保護接地故障類型的設備和公共汽車超載或地面不同。
              High voltage circuit breaker: electrical transmission network is defined as high voltage, but in power transmission work, it is usually considered to be 72.5kV or higher, according to the recent definition by an International Electrotechnical Commission (IEC). The people of high-voltage circuit breakers are almost electromagnetic, and the relay protection plan through the operation of current sensing protection relay in the substation may be very complex. The equipment of protective grounding fault type is different from that of bus overload or ground.
