電梯安全回路(lu)：

三、西安別墅電梯安(an)全回路的安(an)全部件開關：

1、限(xian)速(su)(su)器(qi)開(kai)關(包括限(xian)速(su)(su)器(qi)斷(duan)繩開(kai)關)——當(dang)電梯(ti)的(de)速(su)(su)度(du)超過額定(ding)速(su)(su)度(du)一定(ding)值(至少等于額定(ding)速(su)(su)度(du)的(de)115%)時，其動作(zuo)能導(dao)致安全鉗起作(zuo)用的(de)安全裝置。

2、檢(jian)(jian)修(xiu)開(kai)關——分為控制柜檢(jian)(jian)修(xiu)開(kai)關、轎內檢(jian)(jian)修(xiu)開(kai)關和轎頂(ding)檢(jian)(jian)修(xiu)開(kai)關。三處檢(jian)(jian)修(xiu)開(kai)關互(hu)鎖，防(fang)止誤動作，保證維(wei)修(xiu)人(ren)員的安(an)全。

3、底坑緩(huan)沖器開關——該裝(zhuang)置位于井道(dao)底部，設置在(zai)轎廂(xiang)和對重的(de)行(xing)程(cheng)底部極限(xian)位置。在(zai)緩(huan)沖器(一種用(yong)來吸收(shou)轎廂(xiang)和對重動能(neng)的(de)彈(dan)性緩(huan)沖安全裝(zhuang)置。)動作后(hou)回復至其正(zheng)常伸長位置后(hou)電梯才能(neng)正(zheng)常運行(xing)，為檢查緩(huan)沖器的(de)正(zheng)常復位所采用(yong)的(de)開關裝(zhuang)置。

4、上、下極(ji)限聯鎖開關(guan)——當轎廂運行超越平層磁感應裝(zhuang)(zhuang)置(zhi)(zhi)(zhi)時，在(zai)轎廂或對重(zhong)裝(zhuang)(zhuang)置(zhi)(zhi)(zhi)未接(jie)觸緩(huan)沖(chong)器(qi)之前，強(qiang)迫切斷主電(dian)(dian)源(yuan)和(he)控制(zhi)電(dian)(dian)源(yuan)的(de)非自(zi)(zi)動復位的(de)安全(quan)裝(zhuang)(zhuang)置(zhi)(zhi)(zhi)。該(gai)裝(zhuang)(zhuang)置(zhi)(zhi)(zhi)設(she)置(zhi)(zhi)(zhi)在(zai)盡可能接(jie)近端站時起作(zuo)用而無誤動作(zuo)危險的(de)位置(zhi)(zhi)(zhi)上。應在(zai)轎廂或對重(zhong)(如(ru)有)接(jie)觸緩(huan)沖(chong)器(qi)之前起作(zuo)用，并在(zai)緩(huan)沖(chong)器(qi)被壓縮(suo)期間保(bao)持(chi)其動作(zuo)狀(zhuang)態。對強(qiang)制(zhi)驅(qu)動的(de)電(dian)(dian)梯(ti)，極(ji)限開關(guan)的(de)作(zuo)用是(shi)直(zhi)接(jie)切斷電(dian)(dian)動機(ji)和(he)制(zhi)動器(qi)的(de)供電(dian)(dian)回(hui)路。極(ji)限開關(guan)動作(zuo)后，電(dian)(dian)梯(ti)不能自(zi)(zi)動恢復運行。

5、安(an)全鉗開(kai)關(guan)——檢測(ce)限速器是否動作。若限速器動作時，使轎廂或對(dui)重(zhong)停止運行保持靜(jing)止狀態，并能夾緊在(zai)導軌的機械(xie)安(an)全裝(zhuang)置。

6、安全窗開關(guan)——指轎廂安全窗設(she)有手(shou)動上鎖的安全裝置，如果鎖緊失效，該裝置能(neng)使電梯停止。只有在重新(xin)鎖緊后，電梯才有可能(neng)恢復(fu)運行。

7、廳門(men)、轎門(men)聯(lian)鎖(suo)開關——廳門(men)、轎門(men)關閉后鎖(suo)緊(jin)，同時(shi)接通(tong)控制(zhi)回(hui)路，轎廂方可運行(xing)的(de)機電(dian)聯(lian)鎖(suo)安全(quan)裝置(zhi)。其(qi)(qi)作(zuo)用(yong)是(shi)當電(dian)梯(ti)轎廂停靠在某層(ceng)站(zhan)(zhan)時(shi)，其(qi)(qi)它層(ceng)站(zhan)(zhan)的(de)廳門(men)是(shi)被有效鎖(suo)緊(jin)的(de)，如果一旦(dan)被開啟電(dian)梯(ti)則不(bu)能正常啟動或保持運行(xing)。

8、盤手(shou)輪開關(可選)——當電梯發生(sheng)故障，轎廂(xiang)停靠在兩層站之間時，切斷盤手(shou)輪開關，松(song)開安全鉗(qian)，轉動(dong)盤手(shou)輪，可使轎廂(xiang)到達較近(jin)的層站。

9、超速(su)保護開(kai)關(可(ke)選)——能檢測出(chu)上行(xing)轎(jiao)廂的速(su)度(du)失控，并能使轎(jiao)廂制停，或(huo)至少使其速(su)度(du)降低至對重緩沖器的設計范圍。 四、安全回路作用
