Arc protection device HFBR 4503/4513Z Connector

What is an arc flash?

Human safety is critical to utilities and industries, including oil, gas, water, wastewater, and metals and mining.

Arc flash is a hazardous situation with a release of energy.

The energy from an arc flash event can cause injury.

How is the arc generated?

Arc flashes occur when the insulation or air separation between energized components within a circuit is compromised. Arc flash events can be caused by a number of factors, such as a two-phase short circuit, which can cause phase-to-phase faults.

Danger of Arc Flash

Arc flash events can result in dangerous and potentially lethal heat, ultraviolet radiation, explosion pressure, flying shrapnel, and deafening sound waves.

How to solve such problems?

Arc protection at the speed of light:

Protect people and equipment

• Technology and overcurrent detection

• To reduce the likelihood of injury

• Reduces arc incident energy levels by up to 88%

• To increase safety and minimize equipment damage

• Safely detect arc flash by using a combination of light sensors

Benefits of Arc Flash Protection

1. High speed trip:

Relays reduce the risk of arcing by reducing overall troubleshooting time.

2. Reduce accident energy:

The faster the arc flash event disappears, the lower the incident energy. The relay detects an arc flash hazard and sends a trip signal to the circuit breaker within 2 ms.

Shown here (before any cleanup is done) is the inside of a switchgear protected by SEL light sensing and overcurrent protection during a 6.6 kV arc flash event. Damage is limited to arcing on the cable termination bolts.arc protection device

Arc protection solutions

Bare fiber sensors detect light from arc flashes over the entire length of the fiber loop. This type of sensor is used for large areas,

Easy-to-install point sensors such as busbars detect light from arcs. This type of sensor is used in areas such as closed circuit breaker rooms.arc protection device

Shenzhen Jinzhi Optoelectronics Technology Co., Ltd. provides induction series products for arc protection solutions

1. Jinzhi provides: light detection point sensor

Model：KINZ-CG01&KINZ-CG02

Plastic Fiber Optic Connectors for Point Sensors

The light that meets the point sensor is captured and fed into a plastic optical fiber (POF). The self-supervision function is achieved through the built-in coupling between the two fibers.

For connecting duplex POF cables to point sensors. The special sensor design based on POF allows system engineers to avoid any galvanic contact between the arc flash area and the detection electronics.

Both KINZ-CG01 and KINZ-CG02 are part of a comprehensive arc inspection product portfolio. In combination with sensor transceivers, they are designed to detect arc flash events in electrical grids.arc protection device
