繞線式水阻啟動柜工作原理？球磨機用水阻柜起動好不好？水阻柜能頻繁起動多少次？
繞線式水阻啟動柜概述
I. Overview
ZDR系列液體電阻起動器是為了進一步改善大、中型繞線式異步電動機的起動性能而研制成功的新一代起動控制裝置，通過在被控電動機的轉子回路中串入液體電阻，隨電動機起動時自動投入并在預定的時間內自動、無級、連續(xù)切除，克服了頻敏變阻器、油浸變阻器、鑄鐵變阻器等老式起動控制設備沖擊電流大（一般約為額定電流的3～5倍），起動不理想等不足，使電機在理想的起動電流條件下平穩(wěn)起動，均勻升速，對保護電機、用電設備、電網及節(jié)能等方面有****。該設備在起動、停止、故障保護、聯絡、報警、顯示等方面、精心設計，與其它老式起動器相比較，具有自動化程度高、起動電流小（一般小于額定電流的1.3倍）、電氣及機械沖擊小、特別適宜于重載起動等特點，電網電壓低亦能順利起動，**了變壓器的容量，是目前球磨機、提升機、破碎機、壓縮機、風機、水泵等重負載的*理想的起動控制設備。
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.
