1.背(bèi)景信息Background

現代(dài)化工(gōng)工(gōng)業(yè)中，電動(dòng)機(jī)作(zuò)為一種(zhǒng)拖動機(jī)械(xiè)，成為所有動力機(jī)械基礎(chǔ)，科(kē)學(xué)技術(shù)不(bù)斷進步和(hé)工(gōng)藝控製(zhì)不斷*，尤(yóu)其(qí)是(shì)自動(dòng)化生(shēng)產(chǎn)要求，迫(pò)切(qiē)需(xū)要(yào)開(kāi)發和(hé)*電動(dòng)機控(kòng)製和保(bǎo)護設備(bèi)，實(shí)現(xiàn)對(duì)生(shēng)產(chǎn)過程和大(dà)型機(jī)械(xiè)遙(yáo)控，遙(yáo)測，遙調，故障(zhàng)診斷(duàn)以(yǐ)及集中控製等(děng)功(gōng)能(néng)。

In modern chemical industry,  as a mechanical drag, electric motor become the foundation of all machinery. Improvement of science and technology progress and process control, especially the automation production requirements, make it urgent to develop and improve the motor control and protection equipment , so as to realize the function remote control, remote sensing, remote setting, fault diagnosis, and centralized control of of the production process and large machinery.

  同(tóng)時，化(huà)工(gōng)行業具(jù)有大(dà)通量，滿(mǎn)負荷(hé)連(lián)續(xù)運(yùn)轉特點(diǎn)，對電機(jī)設備(bèi)可靠性(xìng)和穩(wěn)定(dìng)性要求較高，一旦(dàn)發(fā)生(shēng)事(shì)故，須馬上查找故障(zhàng)原(yuán)因(yīn)並及時除(chú)掉，以(yǐ)保證及時恢復生產，對(duì)於過(guò)去一直采用熱繼電器作為電(diàn)動機(jī)過(guò)載保護(hù)和(hé)控製(zhì)元件，受(shòu)到(dào)元件(jiàn)質(zhì)量和(hé)工(gōng)藝限(xiàn)製(zhì)，已(yǐ)無法(fǎ)滿足(zú)日(rì)益發展(zhǎn)化(huà)工工業自動化(huà)要(yào)求，而(ér)新型的智(zhì)能電(diàn)動(dòng)機保(bǎo)護(hù)器，能夠滿足對電動(dòng)機的(dí)保(bǎo)護控(kòng)製要(yào)求(qiú)，作(zuò)為(wéi)電動機保(bǎo)護元件，電動(dòng)機保護器(qì)合理(lǐ)保障(zhàng)了(liǎo)電機安全運行，取代了熱繼電(diàn)器(qì)，利用通(tōng)訊(xùn)技術，實(shí)現(xiàn)了電機(jī)控(kòng)製自(zì)動化(huà)，並(bìng)取了顯(xiǎn)著(zhù)經(jīng)濟(jì)效益.

At the same time, the chemical industry have the characteristics of large flux, full load continuous operation, has high requirements for electrical equipment reliability and stability.Once there is an accident, the cause of the problem must been quickly checked and problems must been promptly eliminate, in order to timely recover to produce.In the past ，thermal relay have been used for motor overload protection or use as control components, but limited by component quality and technology, have been unable to meet the development of chemical industrial automation requirements, and new type of intelligent motor protector, can meet the requirement of the protection of motor control. As a motor protection device, motor protector effectively guarantee the safe operation of the electric motor, replaced the thermal relay, By using advanced communication technology, has realized the motor control automation, and take the significant economic benefits.
