10kV Short Circuit Current Limiter

Listing date: 2018-04-28

DDX1 short-circuit current limiter (abbreviated as current limiter) is an ultra-high-speed switch with strong short-circuit current breaking ability. The short-circuit fault can be completely cut off within 10ms after the short-circuit fault occurs and before peak value of the pre-expected short-current is arrived. It combines blasting cutting technology, current-limiting fuse technology, high voltage insulation technology, electronical measurement and control technology perfectly. It realizes quick current-limiting cutting-off of short-circuit current of power generation, power distribution and power consumption systems, and prevents main equipment of the electric system such as generators, transformers from being impacted by catastrophic short-circuit current. At the same time, the operation mode of the power distribution system can be improved to achieve the effects of saving energy, improving power quality and improving power supply reliability.

Product Characteristics and advantages

◆ Strong short-circuit breaking capability ( large capacity ): rated breaking short-circuit current is 50kA~200kA

◆ Breaking speed is fast ( high speed ) :Total breaking duration:<10ms

◆ The breaking process has obvious current limiting characteristics ( current limiting )

◆ The action criterion adopts current instantaneous value and current change rate instantaneous value

◆The current sensor is integrated with the fast-speed disconnector, and the structure is simplified

◆ The electronic controller works independently in three phases through high temperature and strong interference tests to ensure the overall reliability of the product.

Product Usage

◆ Bypass current limiting reactor (energy saving, consumption reduction, reactive power elimination and power supply quality improvement)

◆ Parallel operation of sectionalized buses in large-capacity distribution system (optimizing load distribution and reducing network impedance)

◆ Short circuit protection of generator outlet or transformer low voltage side

◆ Short - circuit Protection of Branch Busbar and High Voltage Transformer in Power Plant
