TVOC-2-240 1SFA664001R1001 ABB Arc Monitor

Product Description

The TVOC-2-240 1SFA664001R1001 ABB arc monitor is used to monitor arc flashover phenomena in industrial equipment.

feature

High sensitivity

Can effectively detect arcing phenomenon

The design of the TVOC-2-240 1SFA664001R1001 ABB arc light monitor adopts a modular concept,suitable for all types of low and medium voltage switchgear,and has obtained functional safety(SIL-2)certification,and complies with IEC61508 and IEC62061 standards.These standards ensure the reliability of the product.This certification is consistent with the d-level performance requirements in EN ISO13849-1.Security functions are handled by specialized hardware.In addition,the operation menus of the system,trip logs,and user-friendly interfaces are processed by the microprocessor.

The system can be set to trip the specified circuit breaker based on which light sensor detects light.This function can be set through a dial switch,and automatic reset and current sensing units can be set.The energy stored in the system can support operation for 0.2 seconds after power interruption,which is sufficient to ensure the tripping circuit operates,even in the event of a short circuit fault or voltage disappearance.Note:The circuit breaker still requires a backup power supply as the working power supply for the trip circuit.All wiring connections can be made on the front of the arc monitor.The plug-in terminal block helps to complete the wiring before TVOC-2 is installed in the switchgear.The solid-state tripping contact is an IGBT type,which can ensure fast and reliable tripping.

The TVOC-2 arc monitoring system adopts the famous TVOC design,which focuses more on the reliability,flexibility,and simplicity of the product.This system can provide reliable arc fault solutions for various devices,eliminate potential hazards,and protect personnel and equipment safety.Typical applications include all low-voltage switchgear and medium voltage switchgear.

The TOC-2 arc protection system is an arc protection relay that can slow down arc faults and help protect personnel and equipment.The arc monitor is the main unit of the arc protection system,which detects arc light and sends a telecommunications signal within the 1MS range to the nearby circuit breaker through a fast IGBT contact.The circuit breaker will cut off the power supply and extinguish the arc light.The arc monitor has 10 detector inputs and can selectively jump to three circuit breakers if needed.A maximum of 2 expansion units can expand the number of photodetectors to 30,including an HMI that can be placed outside the door.The sales range of detectors is wide to accommodate a complete switchgear design.Power supply voltage 100…250 V DC or 100 V 240 VAC 50/60 Hz.Accessories include current sensors,optical cables,cable straps,etc

application area

The TVOC-2-240 1SFA664001R1001 ABB radian monitor is widely used in power systems and equipment in industries such as power,petroleum,chemical,and steel.
