Multifunctional microcomputer controller
The multifunctional microcomputer controller is the intelligence type equipment researched and developed by our company independently. It can monitor line current, voltage. While the high (low) voltage controlling box has the fault of on switch over-, over current, over voltage and line fault etc on working condition, it can automatically delayed off switch control, and automatically delayed switch on according to pre-settlement. This product can make high voltage controlling box realize part functions of minitype transformer substation.
1). Normal working current point: when reach or surpass the setting current point (means the second current of current inductance implement, the high voltage corresponding circuit should calculate according to CT ratio changing), it takes delayed over current cut off. Setting scope is 4-7A, real display is 4-7. It changes 1A while setting.
2) Fast cut off current point: when reach or surpass the setting current point (the second current of CT), that is the implementation of Quick Break Trip Delay. Setting scope is normal working current point +1-30A. Real display is 5-30. It changes to 1A while set every time.
3) Reclosing (Peak current) delayed period: During this period, over current is ignored. However, when reach settled quick break current point, which will undertake Quick Break Delayed reclosing. The Setting scope is 1-10s; real display is 1-10, change to 1s each time.
4) Quick break delayed: When over- current reach or surpass the setting period continuously which will trip soon . The setting scope is 0-2s; real display is 00-20, change to 1s each time.
