fault indicator is a kind of real-time monitoring device which is installed in the power distribution network system, which is a kind of real-time monitoring device for the short circuit and single phase grounding fault in the power distribution network system. Line failure, the staff can use the indicator of the alarm, quickly determine the fault section, and find out the fault point. At the same time, the alarm information can be sent to the monitoring center of the server, in the monitoring of the computer's screen shows the location of the fault location and location, guide line patrol personnel quickly identify the fault section and find out the fault point. The indicator provides the best way to solve the problem of fault finding. It is very important to improve the working efficiency, shorten the time of power supply, recover power supply and improve the reliability of power supply and economic benefit.

two, the main function of

1. short circuit warning:%d%a short circuit sensor detection circuit in the work, when the line short-circuit fault current to achieve or exceed the current value of the short circuit, the short circuit sensor sends out the alarm signal, through the wire (fiber) transmitted to the host, the host receives the signal, resulting in the corresponding alarm signal. %d%a grounding alarm indicator:

2. ground sensor detects the zero sequence current in the work, when the line is connected to the ground current to meet or exceed the ground current setting value, the ground sensor sends out the alarm signal, through the wire (fiber) transmission to the host, the host receives this signal to generate the corresponding alarm signal

3..

4. worker: when the indicator is generated, it can be maintained by pressing the "reset / test" button on the host panel for 2 seconds.

5. automation: indicator generates alarm indication signal corresponding to the alarm signal output, remote. The indicator can also receive a remote reset signal, and remote reset operation for the indicator.

6. test: the indicator can be self check.

installation

1. Installation of the host: host

can be installed in the ring network cabinet (power distribution cabinet, cable branch box, etc.) on the front panel, the disassembly of the host must press the metal clips on the machine shell.

host size: mm 96*48*80 size: mm

2 92*44. Short circuit sensor installation:

short circuit sensor must be installed in the cable of the single phase, the installation can be directly installed on the cable, and the fastening, to prevent slipping and cause off.

3. Ground sensor installation:

ground sensor installation should pay attention to when the cable is surrounded by three wires, cable

grounding wire must be back through the sensor, and fastening, to prevent slipping caused by falling off.
