Q:How to classify fuses

Temperature fuse is divided into low melting point alloy and the temperature of the shape of the shape of the shape of the memory alloy and so on

Q:Why is the fuse broken

Too much electrical appliances, burn insurance, just like with a leakage protection switch, if the power is too large load will be too large trip.

Q:Fuses are generally not overloaded.

No limit measures can be taken after the load current has increased.

Q:What material is used for the fuse

fuse is made of lead and antimony alloy; the second part of the electrode, usually two, it is an important part of the melt and circuit connection, it must have Good conductivity, should not produce a significant installation of contact resistance

Q:What is a spiral fuse:

Once the melt is blown, the indicator pops up immediately and can be seen through the glass hole on the porcelain cap

Q:Fuse according to the breaking current range can be divided into several

This fuse is mainly used to protect power transformers and general electrical equipment.

Q:What is a quick fuse:

Fast fuses are mainly used for short circuit protection of semiconductor rectifier or rectifier devices

Q:Fuses should be repaired with the power distribution unit at the same time:

Check that the fuses are not allowed on the N-line of the TN grounding system and the grounding protection line of the equipment.

Q:What are the fuse, automatic repair fuse what principle

According to the protection of the form, can be divided into: over-current protection and overheating protection

Q:The fuse is to prevent the circuit

the circuit will produce a lot of current through the fuse, the fuse will heat cut off the power to achieve the role of protection circuit to prevent the circuit
