Rn Series 3-40.5kv 50ka 2023 Made in China New Type Indoor Medium and High Voltage Fuses Link

Basic Info

Product Description

This series of high-voltage AC fuses is suitable for indoor AC 50Hz, rated voltage 3kV-35kV power systems.RN1 and RN3 indoor high-voltage current limiting fuses are used for overload and short circuit protection of power lines. The so-called circuit is the function of a fuse to cut off the short-circuit current before it reaches its peak. RN2 indoor high-voltage current limiting fuse is used for short-circuit protection of voltage transformers, with a breaking capacity of 10002MVA. During a short circuit, momentary disconnection should be carried out by limiting the line current to the minimum value, and the fusing current should be within the range of 0.6~1.8A within 1 minute.

RN1, RN3 and RN2 indoor quartz sand filled fuses are applicable to:(1) The altitude shall not exceed 1000 meters.(2) The temperature of the surrounding medium shall not be higher than+40 ºC and not lower than -40 ºC.RN1 and RN3 type fuses cannot operate in the following environments:(1) Indoor places with a relative humidity greater than 95%.(2) Some places with explosive hazards due to burning goods.(3) Places with severe vibrations, oscillations, or impacts.(4) Areas with an altitude exceeding 2000 meters.(5) Air pollution areas and special humid areas.(6) Special locations (such as for X-ray devices)
