Currently, in order for the circuit to work in the best way, it is necessary that the devices work in sync with each other, but it is still necessary to have the best circuit protection devices to protect the circuit from the damage. problems that adversely affect electrical circuits such as overloads or short circuits in the system. A fuse is a device used to protect an electrical system or circuit. Read this article to know more about the effect of fuse and where to install fuses in electrical circuits.

What is a fuse used for?

What are fuses used for? A fuse is a device used to protect an electrical system or circuit by breaking the circuit. In an electrical circuit, the electrical system when installing a fuse will be protected from phenomena in the circuit such as overload or short circuit causing fire and explosion in the circuit or electrical system.

A fuse is a device used to TTTT protect information, so it is widely used in household electrical circuits and transmission lines. In the electrical circuit of household appliances, disposable fuses are often used for easy replacement when there is a problem: dryer, kettle, coffee maker, etc.

What is the structure of the fuse and where is the fuse installation position in the circuit?

State the structure of a fuse

What is the structure of a fuse? The main structure of a fuse is a fuse connected in series with two conductors in an electrical circuit. The main components of the fuse include: A plastic box or insulating material to fix the fuse, the pins to connect the fuse and the two ends of the electrical circuit conductor, the fuse cap is where the fuse is placed inside, … .

The fuse of the fuse is not in a certain form, but depending on the needs of the user, it can be used on substations, high voltage poles or for civil and electronic use, so fuses have many sizes. , designs, specifications are different for each type of application.

Where is the position of the fuse in the circuit?

Fuse installation position in a circuit is the first to be installed, after the total input source and before the electrical equipment that needs to be protected, usually an electrical circuit or an electrical system only needs 1 fuse but has special equipment. In particular, separate fuses are required for devices to protect the entire circuit or the entire electrical system.

Fuses also have many types, so they can be placed in different specific positions such as: high-voltage fuse, low-voltage fuse, thermal fuse, porcelain fuse, pipe fuse, box fuse, blown fuse, fuse falls by itself…

What is the effect of fuse and technical data written on fuses?

The effect of a fuse in an electrical circuit is to protect the electrical system or protect a device or part of the circuit to ensure the safety of the device, the circuit and the entire circuit. But high-voltage power lines often use special fuses to withstand high currents and can save money on self-falling fuses.

Technical data written on the fuse is the indicator showing the parameters of the fuse, including:

  • Limit the current the fuse can withstand under normal operation.
  • Fuse tripping time when short circuit or overload is encountered.
  • The effective protection of fuses for electrical circuit failures.
  • The operating voltage of the fuse.
  • The ability to adapt to different environments of the fuse.
  • Ambient temperature difference affects the performance of the fuse.
