I. Overview 
The DXN(GSN)-Q/T indoor high-voltage live display is suitable for indoor high-voltage switchgear with AC 50Hz and rated voltage of 7.2kV to 40.5kV. It is used to display the live status of high-voltage lines and can lock related equipment as needed. The high-voltage live display device consists of two parts: the display unit and the sensor. For different voltage levels, the display unit is the same, but the sensor must be selected according to the voltage level.
II. Functional Description
1) DXN-T is an indicative type, mainly used to monitor the live status of high-voltage equipment; DXN-Q is a mandatory type, which not only displays the high-voltage live status but also outputs a locking signal to forcibly lock devices such as disconnectors, cabinet doors, and grounding switches, preventing electrical misoperation and accidental entry into live compartments.
2) Electrical Locking: The DXN-Q display can be used in conjunction with the DSN3 series indoor electromagnetic locks produced by our company. The locking signal from the live display is connected in series with the working circuit of the electromagnetic lock. When the high-voltage line is live, the electromagnetic lock cannot be operated, ensuring that the unit controlled by the electromagnetic lock is not misoperated. Electrical unlocking is only provided when the high-voltage line is de-energized and the display has auxiliary power.
3) For displays with a push-button function, pressing the button shows the live status of the high-voltage equipment. After testing, the button should be reset.
III. Installation and Use
The display is generally installed on the switchgear panel. The protective cables connected to the display are connected to the sensor voltage divider terminals and the corresponding display terminals, respectively. The grounding wire must be reliably grounded.
