In the arc flash detection system, the V-pin interface fiber optic connector connects the special light detection sensor to the signal transmission fiber. When an arc flash occurs, the strong light generated is sensed by the light detection sensor, which converts the light signal into an electrical signal, and then transmits the electrical signal to the control unit or monitoring equipment through the optical fiber connected to the V-pin interface fiber optic connector for processing and analysis.

The following is a detailed introduction to its characteristics and application scope:
Features：
1. High-precision connection
The V-Pin interface can achieve high-precision docking between optical fiber and arc sensors, arc units and other equipment, ensuring the stability and accuracy of optical signal transmission and reducing signal attenuation and loss.
2. Strong anti-interference ability
Optical fiber transmission itself has good anti-electromagnetic interference performance. The V-Pin interface is used with optical fiber to effectively avoid the interference of external electromagnetic fields on arc detection signals and ensure the reliable operation of arc protection system in complex electromagnetic environments.
3. Compact structure
The interface is usually designed to be compact and occupies little space. It is suitable for installation and use in equipment such as switch cabinets with limited space, which is convenient for the integration and layout of arc protection systems.
4. Good sealing
It has good sealing performance, which can effectively prevent dust, water vapor, etc. from entering the interface and affecting the transmission of optical signals. It can adapt to relatively harsh working environments and ensure the long-term stable operation of the interface.
Application Scope
1. Medium and low voltage busbar protection
It is widely used in medium and low voltage busbar protection systems with voltage levels of 35kV and below. It can quickly detect arc faults in the busbar area, send out trip signals in time, cut off the fault source, and protect the busbar and connected equipment.
Switch cabinet arc protection
2. Installed in the switch cabinet and connected to the arc sensor, it is used to monitor the arc situation inside the switch cabinet. When an arc short circuit fault occurs, it will act quickly to protect the switch cabinet equipment and operator safety.
3. Industrial power system protection
In the power system of industrial sites such as factories and mines, it can be used for arc protection of important electrical equipment and lines, ensure reliable power supply for industrial production, and reduce production interruptions and equipment damage caused by arc faults.
4. Commercial building power supply system
It is suitable for the power supply system of commercial buildings such as shopping malls and office buildings to ensure the stability and safety of power supply and avoid the impact of arc faults on normal commercial operations and personnel safety.
