TVOC-2-240 Arc monitor ABB detects and alarms electrical wires

Description

The TVOC-2-240 arc monitor is a device produced by ABB for detecting abnormal conditions in electrical lines and making alarms. Here is a detailed breakdown of the device:

I. Product overview
Make and Model: ABB, model TVOC-2-240.
Product Type: Arc monitor, also known as arc protection relay or arc light monitoring system.
Main function: Detect the arc fault in the electrical line, and notify the user to take measures in time by sending an alarm signal to prevent accidents.
Second, functional characteristics
Fast response: The system disconnects the power supply and extinguishes the arc by detecting the light of the arc and using fast IGBT contacts to send an electrical signal to a nearby circuit breaker within 1 millisecond. This fast response time is essential to prevent damage to personnel and equipment caused by arc failures.
High-precision identification: The use of advanced light detectors and algorithmic analysis technology can accurately identify abnormal arc phenomena.
Modular design: The system has a modular concept and can be configured and expanded according to actual needs.
High reliability: It is certified to functional safety (SIL-2) standards and complies with IEC61508 and IEC62061 standards to ensure the reliability and safety of products.
Third, system composition
The TVOC-2-240 arc monitor mainly consists of arc monitors equipped with optical sensors for detecting electric arcs. For some special applications, additional current sensing units can be added to prevent external factors such as bright light (such as sunlight) from inadvertently triggering the system.

Four, the working principle
The working process of the system can be divided into three stages: detection, identification and action.

Detection: Optical sensors detect the light produced by the arc.
Identification: The arc monitor determines the intensity of the light to determine if it is an arc.
Action: When an arc is identified, the trip contact closes, disconnecting the power supply to extinguish the arc.
5. Application Scenarios
The TVOC-2-240 arc monitor is suitable for a variety of situations where arc failures need to be prevented, such as low and medium voltage switchgear. Its design focuses on product reliability, flexibility and simplicity, and can provide a reliable arc fault solution for a variety of equipment.

Six, use precautions
When using the TVOC-2-240 arc monitor, it is necessary to install it at a key location of the electrical line in order to monitor the operation of the line in real time.
It needs to be combined with the inspection system or equipment provided by ABB to ensure the safe and reliable operation of the electrical line.
Comply with relevant safety specifications and operating instructions to ensure the safety of personnel and the effectiveness of equipment use.
If there is any abnormal situation or failure, the personnel should be notified in time for inspection and maintenance.
