GSN series indoor high-voltage live display deviceDetailed product description：

The GSN series indoor high-voltage live display device is suitable for indoor high-voltage electrical equipment with an AC frequency of 50Hz and a nominal system voltage of 3-35KV. It is used to reflect the live status at the device location and can forcibly lock the switch door and handle to prevent misoperation and entering the live interval, achieving the purpose of preventing errors.


Structural features:
The indoor high-voltage live display device consists of two parts: a sensor and a display, which are connected by outdoor wires as a whole. The sensor is an epoxy resin cast pillar insulator product, and the voltage sensing core rod is cast inside. Its shape can be made into pillar insulators of different heights, sizes, and skirts, and can be used as supporting insulators at the same time. There are two types of displays: prompt type (T) and forced type (Q). The prompt type is used to reflect the live status of the circuit, while the forced type not only has a display function, but also a forced locking function, thereby improving the anti misoperation performance of the supporting products. The forced type uses electronic switches to control electromagnetic locks and achieve forced locking. Voltage indication and forced locking operation are both controlled by the same high voltage signal, but the circuit system is independent and does not interfere with each other. As long as the high voltage circuit is live, even if the display circuit and locking circuit fail simultaneously, the electromagnetic lock is still in the locked state.
