DGSN Type of Charged And fault monitoring and integrated indicator

DGSN-type-of-charged-and-fault-monitoring-and-integrated-indicator

DGSN  type of charged and fault monitoring and integrated indicator [tab] [tab_item title=”Specification”] The main function 1、Ground and short-circuit fault indication Ground and short circuit fault indicator is through the sensor detection circuit to circuit grounding or short circuit fault occurs, the value of the current reach or exceed the set alarm sensor current, short circuit sensor signal instantaneous alarm, through the optical fiber transmission to the host , the host receives the signal, a corresponding alarm indication signal; 2、High pressure charged instructions Sensors or cable casing extract signals and indicator active connections, through the long life of the light-emitting element to realize high-pressure electric luminous indicator. 3、Locking function Host access to extract the signal. Through the op-amp, by the signal processing and electromagnetic lock connection to realize mechanical locking function. 4、 High pressure and electric examination Nuclear phase inverter with test electricity through the high-pressure core hole on the front panel to check two high voltage electric cabinet put oneself in another’s position of phase and check electrical operation; 5、Low pressure alarm indication: Fault indicator part on battery power, when the battery voltage is lower than the normal operating voltage, will produce low voltage alarm indication signal, to remind staff to replace batteries, ensure timely and accurately reflect the high voltage line fault condition. 6、 Automatic reset: After the alarm signal indicator, if no manual reset, after the setting time, indicator can be reset automatically. “Gear” optional, reset time (8 seconds, 6 h, 12 h, 24 h, 48 h, default reset time of 12 h). 7、 Manual reset When after the alarm indicator, indicator that is triggered by main board on the front panel “reset / test” button to cancel the alarm. 8、Remote reset operation Indicator to generate the corresponding alarm indication signal, alarm signal can be output far eastone . Reset signal indicator can also accept the distance, the indicator for the remote reset operation. 9、Automatic test By host panel reset / test button panel L1, L2, L3 and L4 indicator light flashes instructions, flashing automatically reset after nine times, at the same time can also be manually reset, two adjacent self-checking operating time is 2 to 5 seconds.
