Capacitance
compensation digital controlled thrown-and-cut unit
|
| |
Product use£º |
|
The unit is widely used in capacitance compensating
cabinet and is the ideal replacing product for traditional
capacitance compensating thrown-and-cut unit. With a reasonable
structure and low failure rate, it can also prolong the
service life of the compensating capacity. |
|
Operating principle£º |
| The unit carries out thrown action without
surge current and cuts off without high voltage because
it operates at the moment when the voltage crossing zero.
The unit operates upon receipt of action command from
capacitance compensator, the chip-microcomputer controls
the SCR by command to switch in the compensating capacity
and the red indicator turns on. Then the contactor initiates
the attracting immediately and the green indicator turns
on. The SCR quits running according to the command and
the red indicator turns off. When the capacitance compensator¡¯s
switching command is accepted, the red indicator turns
on, the SCR throws in again, the constactor quits running
and the green indicator turns off. Immediately after that
the SCR quits running, the red indicator turns off and
the compensating capacity quits from the compensation
process. |
