      Cutler Hammer KD3400F 斷路器

      時間繼電器在控制電路中用于時間的控制。其種類很多，按其動作原理可分為電磁式、空氣阻尼式、電動式和電子式等，按延時方式可分為通電延時型和斷電延時型?？諝庾枘崾綍r間繼電器是利用空氣阻尼原理獲得延時的，它由電磁機構(gòu)、延時機構(gòu)和觸頭系統(tǒng)3部分組成。電磁機構(gòu)為直動式雙E型鐵心，觸頭系統(tǒng)借用I-X5型微動開關(guān)，延時機構(gòu)采用氣囊式阻尼器。步，安裝操作系統(tǒng)后，首先應(yīng)該裝上操作系統(tǒng)的Service Pack（SP）補丁。我們知道驅(qū)動程序直接面對的是操作系統(tǒng)與硬件，所以首先應(yīng)該用SP補丁解決了操作系統(tǒng)的兼容性問題，這樣才能盡量確保操作系統(tǒng)和驅(qū)動程序的無縫結(jié)合。 第二步，安裝主板驅(qū)動。主板驅(qū)動主要用來開啟主板芯片組內(nèi)置功能及特性，主板驅(qū)動里一般是主板識別和管理硬盤的IDE驅(qū)動程序或補丁，比如Inb芯片組的INF驅(qū)動和VIA的4in1補丁等。如果還包含有AGP補丁的話，一定要先安裝完IDE驅(qū)動再安裝AGP補丁，這一步很重要，也是很多造成系統(tǒng)不穩(wěn)定的直接原因。 第三步，安裝DirectX驅(qū)動。這里一般推薦安裝版，DirectX的版本是DirectX 9.0C。可能有些用戶會認(rèn)為：“我的顯卡并不支持DirectX 9，沒有必要安裝DirectX 9.0C”，其實這是個錯誤的認(rèn)識，把DirectX等同為了Direct3D。DirectX是微軟嵌在操作系統(tǒng)上的應(yīng)用程序接口（API），DirectX由顯示部分、聲音部分、輸入部分和網(wǎng)絡(luò)部分四大部分組成，顯示部分又分為Direct Draw（負(fù)責(zé)2D加速）和Direct 3D（負(fù)責(zé)3D加速），所以說Direct3D只是它其中的一小部分而已。而新版本的DirectX改善的不僅僅是顯示部分，其聲音部分（DirectSound）——帶來更好的聲效；輸入部分（Direct Input）——支持更多的游戲輸入設(shè)備，并對這些設(shè)備的識別與驅(qū)動上更加細(xì)致，充分發(fā)揮設(shè)備的狀態(tài)和全部功能；網(wǎng)絡(luò)部分（DirectPlay）——增強計算機的網(wǎng)絡(luò)連接，提供更多的連接方式。只不過是DirectX在顯示部分的改進比較大，也更引人關(guān)注，才忽略了其他部分的功勞，所以安裝新版本的DirectX的意義并不僅是在顯示部分了。當(dāng)然，有兼容性問題時另當(dāng)別論。 第四步，這時再安裝顯卡、聲卡、網(wǎng)卡、調(diào)制解調(diào)器等插在主板上的板卡類驅(qū)動。 第五步，后就可以裝打印機、掃描儀、讀寫機這些外設(shè)驅(qū)動。 這樣的安裝順序就能使系統(tǒng)文件合理搭配，協(xié)同工作，充分發(fā)揮系統(tǒng)的整體性能。 另外，顯示器、鍵盤和鼠標(biāo)等設(shè)備也是有專門的驅(qū)動程序，特別是一些品牌比較好的產(chǎn)品。雖然不用安裝它們也可以被系統(tǒng)正確識別并使用，但是安裝上這些驅(qū)動程序后，能增加一些額外的功能并提高穩(wěn)定性和性能。
