- Q: What is a closed fuse:
- for the voltage level 500V below the current level of 1KA the following circuit.
- Q: What is the working principle of the fuse
- with its own heat generated by the melt melt,
- Q: Why not tighten the fuse more easily blown
- Not tight or lead wire angle is too small, making the fuse and copper terminals between the contact area is not big enough, contact resistance, heat, easy to melt contact.
- Q: How do the use of circuit breakers in the end?
- The role of thermal relay is the motor overload automatically cut off the power supply
- Q: Why does the fuse fail when the electric shock is electric
- the use of electrical appliances connected to the parallel circuit, the line of fire through the fuse is generally less than the fuse required current, it will not blow
- Q: Why can not the neutral line fuse
- In the electrical safety work specification only provisions of the zero line is not allowed to install insurance,
- Q: Why the fuse resistance is large
- When the circuit fails or abnormal, accompanied by rising current, and the rising current may damage some important devices in the circuit or expensive devices, it is possible to burn the circuit or even cause a fire.
- Q: Why can not change the fuse when replacing the fuse
- Fuse is to limit the current to ensure that the meter does not burn
- Q: Are there any resistance to the fuse?
- Fuse blows and the principle is Joule's law
- Q: What is the use of the fuse?
- Low-voltage distribution system fuse is a security role in the protection of electrical appliances,
