PILZ皮爾茲繼電器原理特點(diǎn)
1、空氣阻尼式時(shí)間繼電器又稱為氣囊式時(shí)間繼電器,它是根據(jù)空氣壓縮產(chǎn)生的阻力來(lái)進(jìn)行延時(shí)的,其結(jié)構(gòu)簡(jiǎn)單,價(jià)格便宜,延時(shí)范圍大(0.4~180s),但延時(shí)精確度低。
2、電磁式時(shí)間繼電器延時(shí)時(shí)間短(0.3~1.6s),但它結(jié)構(gòu)比較簡(jiǎn)單,通常用在斷電延時(shí)場(chǎng)合和直流電路中。
3、電動(dòng)式時(shí)間繼電器的原理與鐘表類似,它是由內(nèi)部電動(dòng)機(jī)帶動(dòng)減速齒輪轉(zhuǎn)動(dòng)而獲得延時(shí)的。這種繼電器延時(shí)精度高,延時(shí)范圍寬(0.4~72h),但結(jié)構(gòu)比較復(fù)雜,價(jià)格很貴。
4、晶體管式時(shí)間繼電器又稱為電子式時(shí)間繼電器,它是利用延時(shí)電路來(lái)進(jìn)行延時(shí)的。這種繼電器精度高,體積小。皮爾茲時(shí)間繼電器可分為通電延時(shí)型和斷電延時(shí)型兩種類型。
德國(guó)PILZ皮爾茲時(shí)間繼電器類型及特點(diǎn)/*皮爾茲時(shí)間繼電器原理以空氣阻尼式時(shí)間繼電器為例來(lái)說(shuō)明時(shí)間繼電器的工作原理
空氣阻尼型時(shí)間繼電器的延時(shí)范圍大(有0.4~60s和0.4~180s兩種),它結(jié)構(gòu)簡(jiǎn)單,但準(zhǔn)確度較低。當(dāng)線圈通電時(shí),銜鐵及托板被鐵心吸引而瞬時(shí)下移,使瞬時(shí)動(dòng)作觸點(diǎn)接通或斷開。但是活塞桿和杠桿不能同時(shí)跟著銜鐵一起下落,因?yàn)榛钊麠U的上端連著氣室中的橡皮膜,當(dāng)活塞桿在釋放彈簧的作用下開始向下運(yùn)動(dòng)時(shí),橡皮膜隨之向下凹,上面空氣室的空氣變得稀薄而使活塞桿受到阻尼作用而緩慢下降。經(jīng)過(guò)一定時(shí)間,活塞桿下降到一定位置,便通過(guò)杠桿推動(dòng)延時(shí)觸點(diǎn)動(dòng)作,使動(dòng)斷觸點(diǎn)斷開,動(dòng)合觸點(diǎn)閉合。從線圈通電到延時(shí)觸點(diǎn)完成動(dòng)作,這段時(shí)間就是繼電器的延時(shí)時(shí)間。延時(shí)時(shí)間的長(zhǎng)短可以用螺釘調(diào)節(jié)空氣室進(jìn)氣孔的大小來(lái)改變。吸引線圈斷電后,繼電器依靠恢復(fù)彈簧的作用而復(fù)原??諝饨?jīng)出氣孔被迅速排出。
時(shí)間繼電器:當(dāng)加上或除去輸入信號(hào)時(shí),輸出部分需延時(shí)或*到規(guī)定的時(shí)間才閉合或斷開其被控線路的繼電器。
皮爾茲繼電器分類:
a,電磁時(shí)間繼電器:當(dāng)線圈加上信號(hào)后,通過(guò)減緩電磁鐵的磁場(chǎng)變化而后的延時(shí)的時(shí)間繼電器。
b,電子時(shí)間繼電器:由分立元件組成的電子延時(shí)線路所構(gòu)成的時(shí)間繼電器,或由固體延時(shí)線路構(gòu)成的時(shí)間繼電器。
c,混合式時(shí)間繼電器:由電子或固體延時(shí)線路和電磁繼電器組合構(gòu)成的時(shí)間繼電器。
