劇場劇院電能質(zhi)量特(te)點:

現階段隨著人們物質(zhi)生(sheng)(sheng)活的(de)不斷(duan)(duan)提高(gao),對精神(shen)素質(zhi)生(sheng)(sheng)活的(de)要求也不斷(duan)(duan)提高(gao),各地文化中(zhong)心不斷(duan)(duan)增加(jia),而作(zuo)為文化中(zhong)心的(de)核(he)心項目劇(ju)場劇(ju)院也在普遍引入現代化的(de)演藝輔助調(diao)控(kong)系統(tong)。劇(ju)場劇(ju)院應用的(de)主要電(dian)氣設備(bei)中(zhong),含有大量(liang)的(de)舞(wu)臺燈光(guang)調(diao)光(guang)設備(bei)及變(bian)頻舞(wu)臺機(ji)械設備(bei)等(deng)(deng)(deng),這些負荷(he)由于其(qi)整流逆變(bian)等(deng)(deng)(deng)工(gong)作(zuo)特(te)性(xing),產生(sheng)(sheng)了大量(liang)的(de)諧波污(wu)染,諧波污(wu)染會引起配電(dian)系統(tong)電(dian)壓、電(dian)流波形畸(ji)變(bian),使得(de)配電(dian)系統(tong)電(dian)能(neng)(neng)質(zhi)量(liang)下降(jiang)。系統(tong)電(dian)能(neng)(neng)質(zhi)量(liang)的(de)低劣可(ke)能(neng)(neng)會影(ying)響(xiang)到(dao)劇(ju)場其(qi)他精密設備(bei)的(de)運行(xing);干擾音響(xiang)設備(bei);導致(zhi)控(kong)制系統(tong)失(shi)靈、紊亂(luan);無故斷(duan)(duan)電(dian);加(jia)大電(dian)氣火災隱(yin)患度;影(ying)響(xiang)通訊及轉(zhuan)播信號(hao)等(deng)(deng)(deng)等(deng)(deng)(deng),嚴重影(ying)響(xiang)劇(ju)院舞(wu)臺的(de)正常(chang)工(gong)作(zuo)、演出,存在巨大的(de)安(an)全隱(yin)患。

 

劇(ju)場(chang)劇(ju)院諧(xie)波污染的特點及現(xian)狀:

劇(ju)場主要(yao)的諧(xie)波(bo)源設備為可控(kong)硅調光設備,其產生(sheng)的諧(xie)波(bo)以3次諧(xie)波(bo)為主(zhu);另外,舞臺變頻機械設備也是系統主(zhu)要的諧(xie)波(bo)源,其產生的諧(xie)波(bo)以5、7次諧(xie)波(bo)為主(zhu); 

 

諧波對劇(ju)場劇(ju)院配(pei)電系統的(de)危害: 

劇(ju)場(chang)配電(dian)(dian)系統諧波(bo)污染將增加(jia)輸電(dian)(dian)、供電(dian)(dian)和(he)用電(dian)(dian)設(she)備(bei)(bei)的額外附加(jia)損耗,使(shi)設(she)備(bei)(bei)的溫度(du)過熱(re),降低設(she)備(bei)(bei)的利用率和(he)經濟效(xiao)益,并給劇(ju)場(chang)增加(jia)額外的電(dian)(dian)能(neng)損耗,嚴重時(shi)可能(neng)造成(cheng)電(dian)(dian)氣火(huo)災,具(ju)有極大(da)的安全隱患。 

 

希拓電氣建議(yi)您(nin)使用無功(gong)補償柜治理諧波:

電容柜工作原理:用(yong)電設備(bei)除電阻性(xing)(xing)負(fu)載外,大部分(fen)用(yong)電設備(bei)均屬感性(xing)(xing)用(yong)電負(fu)載(如日(ri)光燈、變(bian)壓(ya)(ya)器、馬(ma)達(da)等用電(dian)(dian)(dian)設備(bei))這(zhe)些感(gan)應負載,使(shi)供(gong)(gong)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)(ya)相位發生(sheng)改(gai)變(bian)(即電(dian)(dian)(dian)流(liu)滯后于電(dian)(dian)(dian)壓(ya)(ya)),因此(ci)電(dian)(dian)(dian)壓(ya)(ya)波動大(da)(da)(da),無功功率增大(da)(da)(da),浪費大(da)(da)(da)量(liang)電(dian)(dian)(dian)能。當功率因數過低時,以(yi)致(zhi)供(gong)(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)源輸出電(dian)(dian)(dian)流(liu)過大(da)(da)(da)而(er)出現超負載現象。電(dian)(dian)(dian)容(rong)補償柜內的(de)電(dian)(dian)(dian)腦(nao)電(dian)(dian)(dian)容(rong)控制系統可解決以(yi)上弊端(duan),它可根據用電(dian)(dian)(dian)負荷(he)的(de)變(bian)化,而(er)自(zi)動設置。電(dian)(dian)(dian)容(rong)組數的(de)投入(ru),進(jin)行電(dian)(dian)(dian)流(liu)補償,從而(er)減(jian)低大(da)(da)(da)量(liang)無功電(dian)(dian)(dian)流(liu),使(shi)線路電(dian)(dian)(dian)能損(sun)耗降到最低程(cheng)度,提供(gong)(gong)一個高素質(zhi)的(de)電(dian)(dian)(dian)力源。

 

經過諧(xie)波(bo)保護裝置對系(xi)統(tong)諧(xie)波(bo)污染(ran)的治(zhi)理,可以大大降(jiang)低(di)系(xi)統(tong)中諧(xie)波(bo)含量,降(jiang)低(di)系(xi)統(tong)故障率,消(xiao)除系(xi)統(tong)安全(quan)隱患,提高系(xi)統(tong)容量利用率,減少日(ri)常(chang)維(wei)護量,節約(yue)電能。

1、保持(chi)配電系統的供電可靠性(xing)和(he)連續性(xing),保障劇院(yuan)活動及(ji)演出(chu)安全(quan); 

2、降低因諧(xie)波導(dao)致(zhi)的設備(bei)升溫、老化,降容(rong)和(he)損壞,提(ti)高設備(bei)的使用效率,釋放系統容(rong)量(liang),減少電氣(qi)設備(bei)投資; 

3、消滅系統(tong)的一(yi)個安(an)全(quan)隱患點,使安(an)全(quan)防護升級; 

4、提(ti)高電能使用(yong)的功率因數(shu); 

5、提升電能(neng)質(zhi)量(liang),節(jie)能(neng)減排,保(bao)護環(huan)境; 

6、減少由于(yu)電能質(zhi)量(liang)問題帶(dai)來的演出故障及影響,提升服務質(zhi)量(liang)。
