Introduction of BK/HBH-I Fuseholders

BK/HBH-I fuseholders are a type of fuseholders designed for specific applications, primarily to protect circuits from overloads, short circuits, and other electrical faults. They consist of a metal casing, a fuse, and an actuator. The metal casing contains the fuse and actuator, which are activated when an electrical fault occurs. The fuse blows, breaking the circuit and preventing further damage.

Application Fields

BK/HBH-I fuseholders are commonly used in the electrical and electronics industry as well as in telecommunications, instrumentation, and other industrial applications. They can be used to protect sensitive electronics such as computer systems, automation systems, switches, and high voltage equipment from potential faults. They are also used for appliances such as electric ovens, dryers, and electric motors. Finally, they are commonly used in both military and aerospace applications.

Working Principle

BK/HBH-I fuseholders use a current-activated mechanism to detect any electrical fault and interrupt the current flow. This is done by a metal strip which is mounted between the two metal casing pieces. When an overload or short circuit occurs, the current increases and the metal strip is forced against the actuator, which is set to a certain pre-determined value. The actuator then opens a switch which breaks the circuit and prevents further damage.

The metal strip is connected to a spring, which automatically resets the actuator once the fault has been cleared. This process ensures the fuseholders remain safe and accurate even during multiple short circuits or overloads. Additionally, the fuseholder can also be reset manually using a reset key, which allows the device to be brought back to normal operation.

In addition to protecting circuits from overcurrents and short circuits, BK/HBH-I fuseholders also provide protection from voltage fluctuations. The voltage-sensitive metal strip has two bias lines which detect a voltage that exceeds the pre-set value. When an overvoltage occurs, the metal strip will once again be forced against the actuator, opening the switch and breaking the circuit.

Conclusion

BK/HBH-I fuseholders are a versatile and reliable means of protecting sensitive electronics from faults and voltage fluctuations. They are used in a wide range of industries, from military and aerospace to consumer electronics, and are designed to be both accurate and reliable. Additionally, their current-activated mechanism, combined with the manual reset key, allows for quick and easy operation.
