The role of arc suppression coil and domestic Application Comparison


Only discrete points in 2006 to No. 5 LI Jing-wei: the role of Circle Arc Application and Comparison of 73 stalls of domestic regulation, compensation is poor,[link widoczny dla zalogowanych], and has a high level over-voltage grid in the original direction of ground line selector is not available and there is the danger of series resistance and other shortcomings. Because technically backward. Have been frequent in the 6kV power cable joint insulation damage, cable blasting accident, it is difficult to adapt power distribution system safety requirements. Bayer aluminum plant in the Central first production line design. Owned thermal power stations in the main 6.3kVm, Ⅳ access to two paragraphs on the bus were automatic tracking bias Dynamic Compensation Arc, model: zDB a Ⅱ A, then the main 6.3kVI, Ⅱ segment will transfer the original turn-mounted compensation system has been transformed, now a total of four automatic tracking bias Dynamic Compensation Arc run. Automatic tracking bias Dynamic Compensation Arc, model: ZDB a capacity of Ⅱ A: 10kVA, Start voltage: 25V, adjustment range: 0 ~ 160A performance indicators: (1) Working voltage: 380V ± three-phase four-wire 10% (2) Communication Interface: RS232 or RS485 (3) communication: response type (4) capacitive current measurement accuracy: ± 5% (5) residual flow range: less than 5A. (6) File size: 128 New Books last three files and run the ground effect (1) January 22, 2006 of a capacitive current: 107A, inductor current: 101.7A, ground debris flow: 5.35A (2 ) 2005 6 January l2 a capacitive current: 109.3A, the inductor current: 103.8A, ground debris flow: 5.46A (3) 2004 年 9 月 16 Sun Mon capacitive current: 78.4A, the inductor current: 77 .2 A, ground debris flow: 3.16A equipment operation and stability, ground compensation accurately and rapidly (only 20ms), the dynamic auto-tracking compensation, without manual adjustment. Real-time display system capacitive current, earth fault and compensation when the residue after the inductor current flow,[link widoczny dla zalogowanych], with capacitive ground fault current recall function and recall functions. 5 Conclusion of Bias Arc device with a ratio of adjusted air gap and arc suppression device Multitap more superior technical performance,[link widoczny dla zalogowanych], to solve the shortcomings of the latter two can not be overcome, should in future projects to promote use.
