ABB TVOC-2-240

Description

ABB TVOC-2-240 is an arc monitoring system,also known as an arc protection relay,produced by ABB.The following is a detailed introduction to the product:

I.Product Overview

TVOC-2-240 is part of the ABB TVOC-2 arc protection system,designed to mitigate arc faults and protect the safety of personnel and equipment.It detects the light of the arc and uses fast IGBT contacts to send an electrical signal to the nearby circuit breaker in a very short time(within 1 millisecond)to disconnect the power supply and extinguish the arc.

II.Technical Features

Arc Detection:

TVOC-2-240 is equipped with an optical sensor for detecting arcs,which can monitor arc faults in the power system in real time.

Fast Response:

When an arc is detected,the system sends an electrical signal to the circuit breaker within 1 millisecond through fast IGBT contacts to achieve rapid power disconnection and arc extinguishing.

Scalability:

TVOC-2-240 has 10 detector inputs,and the number of light detectors can be expanded to 30 through up to 2 expansion units to adapt to power systems of different sizes.

Multiple installation methods:

The product supports rail or screw installation,providing flexible installation options.

Easy to operate and maintain:

The product has a clear and easy-to-read interface and a simple startup menu,which is convenient for users to install,set up and operate.

No calibration required:

TVOC-2-240 is reliable,quick to install,and does not require calibration,reducing maintenance costs.

3,system composition and working principle

System composition:

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

Working principle:

The working process of the system can be divided into three stages:detection,identification and action.First,the optical sensor detects 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 identified,the trip contact closes and disconnects the power supply to extinguish the arc.

IV.Application Scenarios

TVOC-2-240 is suitable for various occasions where arc faults need to be prevented,such as low-voltage and medium-voltage switchgear.Its design focuses on product reliability,flexibility and simplicity,and can provide reliable arc fault solutions for various equipment.
