10KV high voltage line voltage dynamic regulator ESVR

Views:

Product description:
In the rural power grid, especially in remote mountainous areas, the grid structure is unreasonable, the wire section is thin, the feeder line is long, the power supply radius is large, and the reactive power compensation ability is insufficient. The problem of low power supply voltage is difficult to be fundamentally solved. The ESVR is installed at 1/2 or 2/3 of the head end of the line to ensure the voltage quality of the line, which can extend the power supply radius by 2 to 3 times. The ESVR line voltage dynamic voltage regulator is a power electronic device that ensures the output voltage is stable by automatically adjusting the ratio. It can quickly and automatically adjust the input voltage within 30%, especially suitable for large voltage fluctuations or large voltage drops. Line.

Working principle:
The high-voltage line voltage dynamic regulator compares the voltage on the output side with the reference voltage. If the line voltage deviates, the controller issues a lift command to the on-load tap-changer electronic switch to control the on-load tap-changer to switch from a tap. Go to another tap to change the transformer's ratio to achieve fast on-load auto-regulation.
