Swiss ABB arc light detector TVOC-2-240-C has arrived

Swiss ABB arc light detector TVOC-2-240-C has arrivedTransmit the control signal to the on-site actuator through AO.

TVOC-2-240 is an arc monitoring system from ABB brand, also known as arc protection relay. The system aims to alleviate arc faults and protect the safety of personnel and equipment. The following is a detailed explanation about TVOC-2-240:

Functional features: The system detects the light of the arc and uses fast IGBT contacts to send electrical signals to nearby circuit breakers within 1 millisecond to disconnect the power supply and extinguish the arc. This fast response time is crucial for preventing damage to personnel and equipment caused by arc faults.

System composition: TVOC-2-240 consists of arc monitors equipped with optical sensors for detecting arcs. For certain special applications, additional current sensing units can be added to prevent external factors such as strong light (such as sunlight) from inadvertently triggering the system.

Working principle: The working process of the system can be divided into three stages: detection, recognition, and action. Firstly, optical sensors detect the light generated by the arc; Then, the arc monitor determines the intensity of the light to determine whether it is an arc; Finally, when an arc is detected, the trip contact will close, disconnecting the power supply to extinguish the arc.

Application scenario: TVOC-2-240 is suitable for various occasions that require arc fault prevention, such as low voltage and medium voltage switchgear. Its design emphasizes the reliability, flexibility, and simplicity of the product, providing reliable arc fault solutions for various devices.

Certification and Standards: The TVOC-2 arc monitoring system has obtained functional safety (SIL-2) standard certification and complies with IEC61508 and IEC62061 standards. These standards ensure the reliability and safety of the product.
