工頻耐壓實(shi)驗設計實(shi)驗設計實(shi)操重視法定程序

1）疲(pi)勞(lao)試驗考生應搞(gao)好明(ming)確的分工(gong)，明(ming)確的充(chong)分間的方(fang)式。并(bing)有專(zhuan)業書籍(ji)人監管現場報道(dao)安全性高(gao)及(ji)觀測(ce)試品程(cheng)序。

2）被試品(pin)時先清理掉，并低(di)溫干(gan)燥(zao)，立即傷(shang)害被試品(pin)和試驗裝置帶(dai)來了的誤(wu)差度。

3）而對于中大型耐(nai)壓應力測(ce)(ce)試，基本(ben)都前先(xian)對其進(jin)行空(kong)升耐(nai)壓應力測(ce)(ce)試。即不接試品時升壓至耐(nai)壓應力測(ce)(ce)試端電壓，校對很(hen)多表計，更改球厚度。

4）升壓(ya)(ya)快速不要太快，并必需以防忽然(ran)(ran)后加壓(ya)(ya)。隨后調壓(ya)(ya)器沒有在零位(wei)時忽然(ran)(ran)分閘。我不要忽然(ran)(ran)截斷(duan)電(dian)源模塊，通常情況(kuang)下(xia)應在調壓(ya)(ya)器降低零位(wei)時拉閘。

5）當電(dian)阻升為現(xian)場實驗(yan)檢測(ce)(ce)電(dian)阻時，展開手表，到(dao)1min后，飛速穩壓到(dao)1/3現(xian)場實驗(yan)檢測(ce)(ce)電(dian)阻以內時，才(cai)可以往上拉開關(guan)電(dian)源。

6）在升壓或抗壓實(shi)驗全(quan)過程中(zhong)，如出現(xian) 下類一(yi)(yi)高(gao)一(yi)(yi)低常情況發生時，應隨(sui)時降血壓，立即切斷電(dian)。關閉實(shi)驗并核實(shi)原由：①電(dian)阻表表針搖動太大；②出現(xian) 絕緣帶燒(shao)掉(diao)或燒(shao)焦；③被試(shi)品內有一(yi)(yi)高(gao)一(yi)(yi)低常的(de)手機聲音。

7）耐壓校(xiao)正(zheng)校(xiao)正(zheng)前后輪應測試隔絕電容，檢杳隔絕問題。

一、的產品概要

變壓器和互感器的感應耐壓試驗是保證變壓器質量符合國家標準的一項重要試驗。變壓器繞組的匝間、層間、段間及相間絕緣的縱絕緣感應耐壓試驗，則是變壓器絕緣試驗中的重要項目。基于縱絕緣試驗中的特殊性，需要通過施加倍頻電源裝置，以提高繞組間絕緣的試驗電壓，從而達到耐壓試驗的目的。
是為滿足上述要求而設計制造，經過廣大用戶使用證明：其操作簡單、性能可靠、能較好地滿足變壓器、互感器感應耐壓試驗的需要。

二、上班的原理

由三臺單相變壓組成，其工作原理如圖一

三、高技術基本參數

容 量KVA	插入工作電(dian)壓(三相四(si)線制)	轉換線電壓	輸出精度電流值	外觀形狀的尺寸	質 量
3	380V	260V	20A	450×250×320	40kg
5	380V	400V	20A	470×260×320	50KG
12	380V	560V	25A	490×260×335	78kg
24	380V	640V	30A	680×280×400	150kg

四、SFQ使用方法

為分體式式儀器(qi)。即幾倍比較嚴重生(sheng)器(qi)和(he)幾倍頻控住(zhu)(zhu)設(she)備，并(bing)包括濾過呵護，交流電表(biao)、幾倍頻導出、線電壓表(biao)，以(yi)(yi)開始(shi)跟蹤和(he)有利于運行(xing)，其控住(zhu)(zhu)設(she)備的面版上接線兩端柱(zhu)與(yu)服務器(qi)拼(pin)接手(shou)段以(yi)(yi)下圖圖甲中：

（按布線(xian)圖將本控制系統連通配電線(xian)路中，注(zhu)重設配的接地）

事情電源模塊輸入	五倍頻相電壓放入	二相150HZ	220V150HZ	保護接地
單相電220V	380V	錄入	輸出精度

按下列步驟(zou)去操作的：

１、接通電源，合上空氣開關，則控制裝置綠色指示燈亮。
２、將調壓器回零，啟動紅色按鈕，則三倍頻發生器通電運行，調壓器等待升壓。
３、將調壓器調壓至試驗所需電壓值且嚴密監視控制裝置中的電流和電壓值，并作好詳細記錄。

４、需在實驗室(shi)檢(jian)測(ce)(ce)環(huan)節中，被試(shi)品造成匝間(jian)、層間(jian)或(huo)段(duan)間(jian)、兩色相間(jian)接地(di)電(dian)壓(ya)擊(ji)穿(chuan)跡(ji)象，則控住漏電(dian)開關(guan)中實驗室(shi)檢(jian)測(ce)(ce)交流電(dian)加大，接觸器設備可即(ji)時脫(tuo)扣，關(guan)機。

５、耐壓再次，將調壓器退回(hui)去零(ling)位(wei)。

五、外接補償問題：
對容性負載如高壓試驗變壓器、電容式電壓互感器可不外接補償，或外接感性補償。對感性負載，一般外接容性補償，其補償值為感性負載容量的50％。
