ABB TVOC-2-240

Description

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

1.Product Overview

ABB TVOC-2-240 is a device launched by ABB brand for monitoring and protecting arc faults in electrical systems.It uses advanced arc monitoring technology,which can monitor arc faults in electrical systems in real time,and issue alarm signals or execute tripping instructions in time when faults are detected to protect the safety of personnel and equipment.

2.Technical Features

High reliability:

Adopt high-quality materials and manufacturing processes to ensure stable operation in harsh industrial environments and reduce failure rates.

Certified by functional safety(SIL-2)standards,it complies with IEC 61508 and IEC 62061 standards to ensure product reliability and safety.

ABB TVOC-2-240

High sensitivity:

Equipped with optical sensors for detecting arcs,it can monitor tiny arc faults in electrical systems in real time.

Fast reaction speed,it can send electrical signals to nearby circuit breakers within 1 millisecond to disconnect the power supply and extinguish the arc.

Easy maintenance:

With self-diagnosis function and fault prompt function,it is convenient for users to perform maintenance and troubleshooting.

Simple design,easy to install and configure.

Multi-function:

It can be connected with a variety of control systems and equipment to realize real-time data transmission and control.

Support remote communication function,convenient for remote monitoring and operation.

Wide voltage range:

Suitable for power supply voltage range of 100250V DC or 100240V AC 50/60Hz.

III.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.

4.Application scenarios

ABB 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.
