SUMMARIZE
AFR-3S Arc flash relays are mainly used to detect arc faults in electrical systems and protect equipment and personnel in electrical systems from arc faults. The arc flash protection relay can detect arcs by monitoring parameters such as current, voltage, and electric power, and quickly disconnect the power supply before an electrical fire occurs, thereby reducing the risk of fire.

AFR-3S Arc flash relay is usually used in medium and high-voltage power distribution systems, control cabinets, transformers, generators, motors, and other electrical equipment. They adopt the dual-criteria principle of arc light detection and overcurrent detection and have the characteristics of fast protection action and high reliability.

Function Introduction

Arc protection function
The device is equipped with 3 arc points, which are used to monitor the internal arc faults of the busbar room, circuit breaker room and cable room in the monitoring cabinet, and can choose to configure arc criterion, arc + current dual criterion for protection.

When the optical fiber transmits the light signal from the CT to the host, the host unit will issue an early warning. At the same time, the current sampling element inside the device will determine the real-time current value and the set value. If the real-time protection current is greater than the set value and an arc signal occurs at the same time, the device will send a trip signal to trip the cabinet.

Sensor introduction
Arc sensors are light sensing elements that detect arcs. When no arc fault occurs, the light intensity increases greatly, and the arc sensor converts the optical signal into an electrical signal and sends it to the arc protection or arc extension unit. Arc sensor wiring has no polarity.
The arc light sensor is installed in the relevant parts of the switchgear to monitor those fragile and important parts. Such as the busbar interval in the switchgear, the CT and PT components in the lower part of the switchgear, the contacts of the circuit breaker, the cable connector, etc.

At present, there are three main types of arc light probes in the market: arc light probes, white light arc light sensing probes and ultraviolet arc light sensing probes. Among them, the ultraviolet arc light sensor has the strongest photosensitive ability, and is also the most effective in sensing arc ultraviolet light inside the switchgear. No interference and influence on visible light.

The ultraviolet arc light sensor is designed for arc light spectral characteristics, using special optical materials, polymer blending and doping technology, and optical lens technology. It can filter out the arc light detection sensor probe that interferes with visible light. The ultraviolet arc light probe can quickly detect the arc light that occurs within a range of more than 240 degrees, and transmit it to the control equipment through the optical fiber, so as to quickly cut off the fault at the millisecond level and avoid serious consequences.

Arc sensor parameter comparison:

Circuit breaker failure protection function
The device is equipped with circuit breaker failure protection. when the arc trip occurs, the device will judge the real-time value of the protection current. when the current is lower than the set value, the failure protection will not operate.

When delay occurs after the action, the current value is still higher than the set value, the device will activate the failure protection and output an independent trip signal to the upper level switch to cut off the fault.
