I. Overview

 ZDR系列作品全自然功率電容啟車器是為了更好地進第一步優化大、大型繞線式異步電動機的啟車耐腐蝕性而取得成功研加工取得成功的新一帶啟車有效把握傳動裝置，在在操縱電動機的定子電路開關中串入全自然功率電容，隨電動機啟車時自然進入并在預訂的日期內自然、有級、多次割除，克制了頻敏變阻器、油浸變阻器、鑄鐵質變阻器等老款啟車有效把握環保主環保設備沖刺直流電大（尋常約為額定直流電的3～5倍），啟車不不錯等達不到，使三相直流無刷電機在不錯的啟車直流電生活條件下平穩性啟車，平均升速，對防護英文三相直流無刷電機、供電環保主環保設備、電力網及綠色建筑等多方向有****。該環保主環保設備在啟車、立即停止、內部故障防護英文、建立聯系、報警、體現等多方向、潛心設置，與任何老款啟車器相對較，兼備自然化水平高、啟車直流電小（尋常小于等于額定直流電的1.3倍）、電器及機器沖刺小、很溫和怡人于輕載啟車等特質，電力網端電壓低亦能盡早啟車，**了低壓變壓器的發熱量，是當今支離大型粉碎機、優化機、支離大型粉碎機、壓縮成機、鼓風機、增壓泵等重根據的*不錯的啟車有效把握環保主環保設備。

 ZDR series liquid resistance starter is a new generation starting controller researched and developed to further improve starting performance of medium and large coil-winding asynchronous motor. By connecting a liquid resistance in rotor loop of motor controlled, which automatically runs upon starting of the motor, and disconnects automatically, steplessly and continuously as scheduled, the following deficiency was overcome: impulse current of obsolete starting controllers such as frequency sensitive rheostat, oil immersing rheostat and cast iron rheostat is strong, and starting process is not desirable. In this case, motor starts under ideal starting current and speed up evenly. The starting controller has significant advantages in protection of motors, electrical devices, power grid and conservation of energy. The controller’s design is elaborate in terms of starting, stopping, protecting against failure, communicating, alarming and displayer. In comparison with obsolete starters, it boast itself of such characteristics, as high level of automation, less starting current (usually being less than 1.3 times of rated current), less electrical and mechanical shock, and it is especially suitable for starting under heavy load. Even in the event that power grid voltage is low, it can start successfully. It reduces capacity of transformer. At present it is a most desirable starting controller for ball mill, hoister, crusher, compressor, fan and water pump under heavy load.

二、功能特殊性

II. Performance and features

1、、機械性能遠更為重要頻敏變阻器、油浸變阻器、碳鋼電阻功率等再啟動器。

 It is superior to frequency sensitive rheostat, oil immersing rheostat and cast iron rheostat in terms of performance.

2、開機啟動瞬時直流電壓小，低于減速機穩定瞬時直流電壓的1.3倍。

 Its starting current is less, which is less than 1.3 times of rated current of motors.

3、可多次工作5次。

It can start for 5 times in succession.

4、線性啟車：對生產設備有廠家承載力震蕩，可拉長廠家生產設備及無刷電機的**。

 Its starting process is smooth: It has no shock of mechanical stress on devices, thus life of machineries and motors are prolonged.

 5、可高壓低壓起步：6千伏交流電動機5.5千伏、380伏交流電動機340伏可順利圓滿起步。

 It can start under low voltage. It can start successfully in 5.5 KV for motors of 6 KV and in 340 V for motors of 380 V.

6、機構簡簡單單、可靠的，全都操控重新化，配置、運維非常方便。

 It is simple and reliable in structure. All operations are in automation. It is easy in installation and maintenance.
