DGSN Type of Charged And fault monitoring and integrated indicator

The cable short circuit and ground fault indicator is a real-time monitoring device installed in the ring network switch cabinet, cable branch box, box transformer and outdoor switchgear in the power distribution network system to indicate the short circuit and single-phase ground fault of the corresponding cable section. When a line fails, the staff can use the alarm indication of the indicator to quickly determine the fault section and find the fault point. At the same time, the alarm information can be sent to the server of the monitoring center in real time, and the area and specific location of the fault will be displayed on the screen of the monitoring computer, guiding the line patrol personnel to quickly determine the fault section and find the fault point. It is of great significance to improve work efficiency, shorten power outage time, quickly restore power supply, improve power supply reliability and reduce economic losses.

The main function of  DGSN  type of charged and fault monitoring and integrated indicator

1Ground 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.

3Locking 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.
