PRODUCTS

APS Arc Protection Device

Arc Protection Relay

市场价:0.00

价格:0.00

RIZNER-APS arc protection device provides fast protection for medium and low voltage busbars in substations, power plants, industrial enterprises and other occasions. When an arc short circuit occurs, the arc short circuit covered by the arc sensor can be quickly positioned, and the arc light protection system operates quickly, cutting off the fault current, and minimizing the damage of the arc light to the equipment and personal injury. RIZNER-APS arc protection system adopts the principle of arc detection and current detection double criterion, which has the characteristics of fast protection action and high reliability. RIZNER-APS arc protection system includes main unit RIZNER-APS100M, satellite device RIZNER-APS101LS (arc current satellite device), RIZNER-APS103LCS (arc satellite device), arc sensor, connecting fiber and so on.
APS II Arc Protection Device

Arc Protection Relay

市场价:0.00

The RIZNER-APS II system (ie RIZNER arc protection system) is a new generation of arc protection system designed for the RIZNER-EagleEye system and redesigned for many years of market and customer feedback. The RIZNER-APSII system consists of a main control unit, a power module, an arc sensor, and an optical fiber line. The system adapts to various operating modes of medium and low voltage busbars, and is flexible and stable.
EagleEye Arc Protection System

Arc Protection Relay

市场价:0.00

价格:0.00

The arc protection system protects the operator from damage and reduces property damage in the event of an arc fault in the switchgear. RIZNER-EagleEye photoelectric arc protection system has been adopted by all major power systems and power companies in the country and its output trip command time is less than 3ms, which can protect the safety of workers even during installation or maintenance . The system consists of a main control unit, an arc unit, an arc expansion unit, a current unit, a current expansion unit, a power module, an arc sensor, an optical fiber, and a data line. Using advanced processor technology and a complete integrated control system, the arc light protection system is logically programmable and adapts to various operating modes of the bus. The output uses Triac technology to ensure that the circuit breaker in the switchgear receives a trip command in the shortest time.
FAST Arc Protection Device

The FAST-Bus arc protection device provides fast protection for medium and low voltage busbars in substations, power plants, industrial enterprises and other applications. When an arc short circuit occurs, the arc short circuit covered by the arc sensor can be quickly positioned, and the arc light protection system operates quickly, cutting off the fault current, and minimizing the damage of the arc light to the equipment and personal injury. The FAST-Bus arc light protection system adopts the principle of arc detection and current detection double criterion, and has the characteristics of fast protection action and high reliability. RIZNER-FAST-BUS arc protection system includes main unit RIZNER-FAST-BUS, satellite device FAST-1S (arc current satellite device), FAST-2S (arc satellite device), arc sensor, connecting fiber and so on.
FLS Arc Sensor, Fiber and Fittings

Arc Protection Relay

The arc sensor can cover a much larger range than its end. Since there are no active or live parts, the sensor is easy to install and does not cause any malfunction, and does not require any maintenance. A lenticular arc sensor is recommended when installing an arc protection system. The illuminance setting of the arc protection system is adjusted on the unit. The illuminance is related to the arc sensor and the length of the fiber. The illuminance setting can be set between 10 – 50KLux. The passive arc sensor specially used for arc protection is installed on the bus line side of the switchgear, and is a light sensing element for detecting arc light. When an arc fault occurs, the illuminance is greatly increased, and the arc sensor directly transmits the optical signal to the main control unit or the arc unit.

OverviewRenewable energy generation, storage and DC loads have been growing significantly in recent years. It is recognised that such strong growth will last for years to come, as investments from government, commercial and private sectors are poured into the sector. However, challenges are also raised for seamless integration to the system. Firstly, the impacts brought into the existing distribution system by renewable energy e.g. PV penetration causes voltage fluctuation, rise, unbalance, harmonics, and islanding effects. These impacts not only cause power quality issue, but also affect system stability and integrity. The second issue is that generation of renewable energy falls out of the peak demand period. Hence better management and re-distribution are required, particular with more and more DC loads being brought into the system e.g. EV charging station and battery storage.The RIZNER FDN Control System includes micro controllers, AD/DC & DC/AC energy routers, seamless switches and sensitive load switch-gear, etc. The DC FDN Control System (DC FDNCS) is the best solution available today to overcome the issues and maximize efficiency of the distributed renewable energy generation and storage.
