Q:Is the fuse the same as the fuse?
Fuses and fuses are the same principle, but the name is not the same, the product shape is not the same, the voltage level current specifications are not the same, the products are the first foreign fuses and domestic 60 years imitation fuse.
Q:What is the working principle of the fuse
with its own heat generated by the melt melt,
Q:When using low-voltage fuses, note that
fuse should be installed vertically to ensure that the socket and the knife holder in close contact,
Q:Why the fuse resistance is large
A fuse is also known as a current fuse, and the IEC127 standard defines it as a "fuse-link". It is mainly due to overload protection.
Q:Why is the fuse broken
There is a short circuit in the circuit, resulting in short circuit current, short circuit current is too large fuse fuse
Q:What is the significance of the voltage on the fuse?
The rated voltage of the fuse is the maximum voltage that can be tolerated when the fuse is disconnected, and the voltage at both ends of the fuse is far less than its rated voltage
Q:What are the characteristics of the fuse?
The rated current of the melt is selected according to the load current of the protected equipment
Q:Fuse tube selection fuse factor
In general, the fuse resistance is inversely proportional to its rated current value. In the protection circuit requires the fuse the smaller the better resistance, so that its loss of power is also small.
Q:Fuse always burn ! Is the line short circuit yet?
But it is best to find the electrician to help replace the appropriate fuse, the fuse is too thick too thick, are not conducive to the protection of home appliances and power.
Q:The choice of fuse tube can be based on the following process
pulse (impact current, surge current, starting current and current transient value) on the life of the fuse tube
We insist on the principle of "Service Supremacy, Quality Primacy" to provide high quality products and best service for the society. After several years' development, we have formed a certain scale in the production of exhaust fans. At present, our mainly products exhaust fans are used in graziery and gardening, cooling pad, automatic oil-burning heating machine, automatic coal-burning heating machine and electric blower fields.
