GCK Low voltage drawout switchgear indoor typeExtraction type low voltage switch
GCK series motor control center is mainly composed of some combined motor control units and other functional units.These units are mounted in a closed metal cabinet in an overlapping manner above and below.Use the horizontal bus set above the cabinet to connect each cabinet together, and the functional units of the same cabinet are in parallel on the vertical bus.The cabinet body is divided into four mutually isolated areas such as horizontal bus area, vertical bus area, cable area and equipment installation area. The functional units are installed in their respective small rooms. When any one functional unit has an accident, it will not affect other units to prevent the expansion of the accident.

This product conforms to the standard of JB tin 9661-1999.This product USES the IP40 protection grade that IEC114 sets, when all doors and guard plate are closed, or when the door is opened and the function unit is moved out of position, all can reach the corresponding protection grade, so as to ensure personal safety.

The product is equipped with reliable grounding system and protection circuit, and all functional units can break the short circuit current according to the specified performance requirements.The incoming line element has three protection features.Therefore, the reliability of power supply and the safety of equipment and system can be guaranteed.

All functional units can be connected with PC cable board (programmable controller) or microprocessor through the interface, which can be used as the execution unit of the automatic control system. According to the needs of users, functional units and function combinations of other contents can also be provided. This product is suitable for ac 380V and 50Hz circuits.

      

 

GCK系列電動機控制中心, 主要是由一些組合式電動機控制單元, 和其它功能單元組合而成。這些單元以上下重疊的方式安裝在封閉的金屬柜體內。 用設置在柜體上方的水平母線,將每個柜體聯結在一起,同一柜體的功能單元則并聯在垂直母線上。柜體共分水平母線區、 垂直母線區、 電纜區和設備安裝區等四個互相隔離區域,功能單元分別安裝在各自的小室內,當任何一個功能單元發生事故時,均不影響其它單元,防止事故擴大。

      本產品符合 JB汀9661-1999標準。該產品采用IEC114規定的IP40防護等級,當所有的門和護板關閉時, 或門開啟時以及功能單元外于移出位置時,均能達到相應的防護等級, 這樣可確保人身安全。
該產品設置有完獸可靠的接地系統和保護電路,所有功能單元均能按規定的性能要求, 分斷短路電流. 進線單元具有三段保護特性。因此,可以保證供電的可靠性,和設備與系統的安全。
      所有功能單元,均可通過接口件與 PC 線板(可編程序控制器)或微處理機連結,作為自動控制系統的執行單元,根據用戶需要還可以提供其它內容的功能單元和功能組合, 該產品適用于交流380V,頻率50Hz的電路中。
Key electrical properties comply with IEC standards of the international electrical commission and NEMA standards of the electrical manufacturers association of America.

Delta each cabinet can separate main and auxiliary circuit isolation transformer, auxiliary circuit operating power supply for 50Hz, 220V;The signal power supply is 50Hz and 6Va

Delta by the main switch with three sections (instant, short delay and overload) protection, for and the next level of the main switch (with instantaneous and overload two sections of protection) with the cancellation of an instant section, to avoid tripping.And has the self - technology, no self - throwing and switching devices for selection.

Horizontal bus with single bus section and not section two, when the use of single bus section, bus switch also has self - cast, no self - cast and switching devices.

Delta motor control circuit has short circuit instantaneous, overload, under voltage release and break bale protection.

The communication contact in each functional unit operates silently and has energy saving function.At the same time, there is a delay (greater than 0.3s, less than 0.5s) release when the power supply disappears.Therefore, if no motor is installed, the respective starting relay can be restored within 0.3s (reclosing or standby power source time is less than 0.3s) to ensure the motor to continue running.

Delta feeder main switch with instantaneous and overload protection, when the user needs, can be installed leakage protection.

Delta lighting and household electrical circuit main switch with instantaneous, overload and leakage protection, this circuit especially in the electric drill, portable grinder and other mobile electrical power supply.

The current circuit contains ammeter, active and reactive watt-hour meter.Ammeter and ammeter can be installed or not in 250A or above feeding circuit.Other circuits larger than 37kW or 60A are fitted with ammeters.A light and alarm device can be installed in case of accident.

 

△主要電器性能符合國際電工委員會IEC標準和美國電氣制造商協會NEMA標準。

△每臺柜 可用隔離變壓器將主、輔電路分開,輔助電路的操作電源為 50Hz, 220V;信號電源為50Hz、 6Va
△受電主開關具有三段 (瞬間、短延時及過載 )保護, 為與下一級主開關 (具有瞬時及過載二段保護)配合,取消瞬間一段,避免了越級跳閘。且具有自技、無自投和切換裝置供選用。
△水平母線具有單母線分段和 不分段兩種,當采用單母線分段時,母聯開關亦具有自投、無自投和切換裝置。
△電動機控制電路具有短路瞬時、 過載、欠壓釋放及斷捆保護。
△各功能單元中的交流接觸采用無聲運行時,具有節能功能。同時,當電源消失后具延時(大于0.3s、小于0.5s)釋放的特性。因此不加裝電機各自啟動繼電器亦能在0.3s以內(重合閘或備用電源自投時間小于0.3s)恢復供電時,保證電動機繼續運行。
△饋電電路主開關具有瞬時和 過載保護,當用戶需要時,可加裝漏電保護。
△照明及家用電器電路主開關具有瞬成時,過載和 漏電保護,本電路尤宣於電鉆、手提砂輪機等移動電器的供電。
