Product Introduction
TXRW1 series and GHTZX1 series special high-voltage current-limiting fuses are one of the main components of DDDXK1 series high-current current limiting circuit breakers/DGXK1 series large-capacity high-speed switches. It is used to extinguish the arc, limit and finally cut off the short-circuit current, the product is safe and explosion-proof, and the end has an action indicator. After the action, the user will replace it by himself, and the manufacturer will provide the user with spare parts at a preferential price for a long time.
Feature
Main parameters
Rated voltage: 7.2~40.5kV
Rated current: 100~300A
Rated short-circuit breaking current: 63~200kA
This product is based on pyrotechnical technology and can be triggered in the initial stage of short-circuit current rise (<1ms) to quickly cut off and limit the peak fault current.
Especially suitable for bus tie section, when the system expansion results in the expected short-circuit current exceeding the breaking capacity of the existing circuit breaker, there is no need to replace the entire switchgear to ensure safety.
Its peak current limiting ratio is 15% to 50%, which means that the actual peak short-circuit current passing through is only 15% to 50% of the expected value, effectively protecting downstream equipment from thermal/dynamic stress damage.
