構建有競爭力的公司-武漢
武漢MOBIS 變速器經(jīng)過短短4年多的發(fā)展生產(chǎn)了優(yōu)秀的產(chǎn)品，因而在中國轎車零部件領域有著首屈一指的地位。
取得這種成果的理由是不僅擁有固有的先進技術而且也是因為重視人才的培養(yǎng)。
以〈信賴經(jīng)營，現(xiàn)場經(jīng)營，透明經(jīng)營〉為經(jīng)營方針；以〈勤勉，儉樸，親愛〉為企業(yè)文化提倡人文文化，致力于個人及企業(yè)的共同發(fā)展。
而且公司內通過現(xiàn)場培訓，海外總公司實習等各個方面的研修教育構成了創(chuàng)造性人才。
追求優(yōu)越工作環(huán)境的同時構建有競爭力的公司，為了培養(yǎng)家族似的人才毫無保留的傾注著所有力量。
此資料是以現(xiàn)代MOBIS管理方式，經(jīng)營方針為出發(fā)點展示了現(xiàn)代MOBIS變速器的新面貌，而且對公司各部門及業(yè)務進行了詳細的敘述。
生產(chǎn)部門把在手動變速器工廠工作的人員必須知道的變速器組裝零件現(xiàn)況和手動變速器變速構造及變速器的作用，對變速器的一般理論以及與生產(chǎn)有關的管理職及現(xiàn)場負責人們看到設備會提出的疑問以圖解的形式進行了說明讓人們更容易理解，而且是以現(xiàn)場管理中使用的樣式、各級別基本遵守的業(yè)務內容為基準整理的。
保全部門擁有對運行率影響最大的非常重要的業(yè)務內容，因此以設備的一般管理理論和對設備故障的事前預防等業(yè)務為重點內容構成，今后通過對設備的準確診斷及評價能使材料對生產(chǎn)活動有所幫助而準備了這些材料。
品質管理部門是以變速器有可能發(fā)生的所有問題為基準，以品質管理的一般業(yè)務及變速器擁有的特點，齒輪加工的主要核心齒形開發(fā)及理論構成，而且通過制作齒輪的切削工具研磨理論可以接觸到更完善的品質理論，因而由今后變速器品質不會發(fā)生誤差的資料所構成。
本書的特點是使讀者能對核心內容一目了然。這樣能在最短的時間內對現(xiàn)代MOBIS變速器培訓有所了解。
最近國家和企業(yè)都在迎接變革，這樣的時期希望此書能帶來一點幫助。
借此對編制此書時在原稿制作及監(jiān)修付出心血給與幫助的變速器職員和使我能像初次入社時的心態(tài)迎接業(yè)務毫無保留的鼓勵及支持我?guī)椭业目偣炯翱偨?jīng)理致謝。
根據(jù)‘稻子熟了會低頭’這句格言希望此教材能像不張揚默默地照亮工作崗位的現(xiàn)代人一樣把深遠的意義傳播出去。
最后祝愿學習此書的所有人借著知識的力量超越現(xiàn)代車繼續(xù)發(fā)展為對全世界重要的技術人才。

6.1 CSC-121A Digital Combined Recloser and Secondary Protection for Circuit Breaker
Function of Device
The device includes functional modules as combined recloser, failure protection, three phase inconsistent protection, charging protection and dead zone protection, etc.
Function & Principle
Protect Startup Component
Each functional module has different startup component. If any startup component of the module is started up, trip & close brake exit positive power supply of whole device will be turned on.
Current differential startup component: when any inter-phase current differential or zero-sequence current differential surpasses startup constant value for four times continuously, protection is started up.
Zero-sequence secondary startup component: zero-sequence secondary startup is mainly applied in functional module of failure protection.
Negative-sequence secondary startup component: negative-sequence secondary startup is mainly applied in functional module of failure protection, which is put into operation when failure function of negative-sequence startup generator transformer unit works.
Function of Combined Recloser
The device provides with four patterns including single phase recloser, three-phase recloser, combined recloser and recloser, being connected into startup recloser circuit on both sides of circuit breaker and satisfying requirement of middle circuit breaker of one and a half circuit breaker. Software and hardware for sidle circuit breaker and middle circuit breaker are the same.
