Description
Grounding position indicator is another important signal device of high voltage switchgear. Its main function is that show the actual working status of the grounding switch. It provides a direct remind for the operator, the grounding switch is closed, grounded,open or isolated.Grounding position indicator can avoid the wrong operations, and maintain the safety of the entire power system.
Its principle is based on mechanical linkage and simple circuit control. The grounding switch has its own special auxiliary contacts, these auxiliary contact connet with its mechanically interlocked. When the grounding switch is closed and grounded, the mechanical movement triggers the matching auxiliary contacts to close, which then turns on the indicator circuit. When the grounding switch is opened and isolated, those auxiliary contacts disconnect the circuit and switch over to the other signal circuit instead.
Grounding position indicator uses high-brightness LEDs as its light source.There are built-in parts that lower the voltage and limit the current in it. It works with the control power supply in the cabinet, There are built in parts that lower the voltage and limit the current in it. It works with the control power supply in the cabinet, converting the higher voltage into the safe working voltage of light. This way, the indicator can run stably for a long time
Different colors are used to distinguish its status: indicator is on that the grounding switch is completely closed and the equipment is grounded; Another color display the disconnected state of the grounding switch
In addition, the grounding position indicator has good insulation performance, voltage resistance, and anti-interference ability. Grounding position indication can adapt to voltage fluctuations in complex power environments,It has a long service life. By real-time circuit switching, continuous and accurate position signal feedback can be achieved, effectively preventing safety accidents such as false grounding and live working, and providing reliable visual support for the daily operation, maintenance, and distribution management of high-voltage electrical equipment.
