DEVICE FOR SHORT-CIRCUIT CURRENT LIMITATION IN POWER TRANSMISSION LINES |
摘要 |
FIELD: electricity.SUBSTANCE: device for short-circuit current limitation in power transmission lines contains transformer, which primary winding W1 is connected in series to the line; it represents a cable section. The line includes also a block of logic circuits which output is connected to switching element control device connected in series to secondary winding of transformer. Switching element is made as in-series bidirectional thyristors and resistor with surge suppressor connected in parallel to them; limitation level of surge suppressor is equal to thyristor class. Control device is connected to exterior power supply source located at potential of power transmission line; it is made as tertiary winding of transformer connected to input of non-controlled rectifier which output is connected to control device.EFFECT: reducing losses in the device in standard operation mode for power transmission; reducing weigh and overall dimensions of the device and preventing repair after each actuation.3 dwg |
