I. Maintenance of Shandong High Voltage Inverter Introducing Wiring of Main Circuit

1. The power supply should be connected to the R, S and T terminals of the input end of the high-voltage converter. It must not be connected to the output end of the high-voltage converter (U, V, W), otherwise the high-voltage converter will be damaged.

2、ZAIDUANZI+,PRJIAN,BUYAOLIANJIECHUJIANYIDEZHIDONGDIANZUQIXUANJIANYIWAIDEDONGXI,HUOJUEDUIBUYAODUANLU。

2. In the terminal +, PR, do not connect anything other than the recommended brake resistor selection, or never short circuit.

江西快33. Electromagnetic interference. The input/output of high-voltage converter contains harmonic components, which may interfere with communication equipment near high-voltage converter. Therefore, install the selected radio noise filter FR-BIF or FRBSF01 or FR-BLF line noise filter to minimize interference.

4、ZHANGJULIBUXIANSHI,YOUYUSHOUDAOBUXIANDEJISHENGDIANRONGCHONGDIANDIANLIUDEYINGXIANG,HUISHIKUAISUXIANGYINGDIANLIUXIANZHIGONGNENGJIANGDI,JIEYUERCICEDEYIQIWUDONGZUOERCHANSHENGGUZHANG。

4. In long distance wiring, due to the parasitic capacitor charging current, the fast response current limitation function will be reduced, and the instrument connected to the secondary side will malfunction.

5、ZAIGAOYABIANPINQISHUCHUCEBUYAOANZHUANGDIANLIDIANRONGQI,LANGYONGYIZHIQIHEWUXIANDIANZAOYINLVBOQI。

江西快35. Do not install power capacitors, surge suppressors and radio noise filters on the output side of high voltage converters.

江西快36、WEISHIDIANYAJIANGZAI2%YINEI,YINGSHIYONGSHIDANGXINGHAODEDAOXIANJIEXIAN。

6. In order to make the voltage drop less than 2%, appropriate type of wiring should be used.

7、YUNXINGHOU,GAIBIANJIEXIANDECAOZUO,BIXUZAIDIANYUANQIEDUAN10minYISHANG,YONGWANYONGBIAOJIANCHADIANYAHOUJINXING。

7. After operation, the operation of changing wiring must be done after the power supply is cut off for more than 10 minutes and the voltage is checked by a multimeter.

江西快32. Introduction to Maintenance of Shandong High Voltage Inverter and Connection of Control Circuit

江西快31、KONGZHIDIANLUDUANZIDEJIEXIANYINGSHIYONGPINGBIXIANHUOSHUANGJIAOXIAN,ERQIEBIXUYUZHUHUILU,QIANGDIANHUILUFENKAIBUXIAN。

江西快31. The terminal of the control circuit should be connected with shielded or twisted pair wires, and must be separated from the main circuit and the high-voltage circuit.

江西快32、YOUYUKONGZHIDIANLUDEPINLVSHURUXINHAOSHIWEIXIAODIANLIU,SUOYIZAIJIEDIANSHURUDECHANGHE,WEILEFANGZHIJIECHUBULIANG,WEIXIAOXINHAOJIEDIANYINGSHIYONGLIANGGEBINGLIANDEJIEDIANHUOSHIYONGSHUANGSHENGJIEDIAN。

江西快32. Because the frequency input signal of the control circuit is a small current, in the case of contact input, in order to prevent bad contact, two parallel nodes or twin contacts should be used for micro-signal contacts.

3、KONGZHIHUILUDEJIEXIANYIBANXUANYONG0.3~0.75PINGFANGMIDEDIANLAN。

3. The cable of 0.3-0.75 square meters is usually used in the connection of control circuit.

3. Shandong High Voltage Frequency Converter Maintenance Introduction Ground Wiring Connection

江西快31、YOUYUZAIGAOYABIANPINQINEIYOULOUDIANLIU,WEILEFANGZHICHUDIAN,GAOYABIANPINQIHEDIANJIBIXUJIEDI。

1. Because of leakage current in high voltage converter, in order to prevent electric shock, high voltage converter and motor must be grounded.

江西快32、GAOYABIANPINQIJIEDIYONGZHUANYONGJIEDIDUANZI。JIEDIXIANDELIANJIE,YAOSHIYONGDUXICHULIDEYAJIEDUANZI。

2. Special earthing terminal for grounding of high voltage frequency converter. The connection of grounding wires should be made by pressing terminals treated with tin plating.

3. The grounding cable should be as thick as possible, and the grounding point should be as close to the high voltage converter as possible. The shorter the grounding line, the better.
