Product Description

Product Description

The DXN8D - Q high - voltage charged display is a charged - state indication and safety - protection device used for indoor high - voltage electrical equipment. It mainly consists of two parts: a sensor and a display. The sensor is usually installed in the cable chamber or bus chamber and is connected to the high - voltage busbar, while the display is mounted on the instrument door of the switch cabinet, used to visually show whether the circuit is charged.

Main Functions

• Charged Indication: It visually shows whether the high - voltage circuit is charged through the display, reminding operators to pay attention to safety.
• Forced Locking: It cooperates with the electromagnetic lock to realize the forced locking function of the switch cabinet door, preventing accidental entry into the charged compartment or misoperation.

Features

• Non - contact Detection: The sensor adopts non - contact technology, which does not need to be in direct contact with the charged body, improving the safety and reliability of detection.
• Directionality: The sensor has obvious directionality and can accurately detect whether the line is charged.
• Self - test Function: The device has a self - test function, which can detect whether its working state is normal.
• Forced Locking Function: Through the locking contact and the electromagnetic lock, it realizes the forced locking of the switch cabinet door to ensure the safety of operators.
• Low Maintenance Cost: Since the sensor is not in direct contact with the charged body, there is no need to conduct partial discharge tests during installation and maintenance, reducing the maintenance cost.
• Long Service Life: It adopts advanced technologies and materials to ensure that the device has a long service life.

Technical Parameters

• Applicable Voltage: It is applicable to indoor high - voltage switchgear such as 6kV, 12kV, 20kV, 27.5kV, and 35kV.
• Operating Frequency: 50Hz.
• Ambient Temperature: Usually from - 25°C to + 40°C.
• Relative Humidity: The daily average is not more than 95%, and the monthly average is not more than 90%.
• Altitude: Not higher than 2,000 meters.

Application Scenarios

The DXN8D - Q high - voltage charged display is widely used in indoor high - voltage switchgear, distribution rooms, substations, and other places, providing important protection for the safe operation of power systems.
