XRNP HIGH VOLTAGE CURRENT LIMITING FUSE WITH HIGH BREAKING CAPACITY FOR VOLTAGE TRANSFORMER PROTECTION
Product Overview
This product is used in indoor AC 50Hz, rated voltage 3.6-40. 3.6-40.KV KV system as the overload and short circuit protection of voltage transformer. (Passed the type test of the National High-VoltageGBl5166.2 Electrical Apparatus Quality Supervision and Testing Center, and the IEC282-1)。 product complies with GBl5166.2 and IEC282-1)
Product structure
XRNP type high voltage fuse adopts plug-in structure, inserting the fuse into the base, which has the advantage of convenient replacement a melt composed of two different metal wires, high resistance and low resistance, and high purity quartz that has been chemically treated as an arc extinguishing medium The sand is sealed together in the melting tube，the melting tube is made of high-strength alumina porcelain with hig temperature resistance. When the line fails, the melt melts and an arc is generated. The quartz sand immediately extinguishes the arc and cuts off the circuit to protect the voltage transformer and its circuit.
