What is liquid fuse?

Liquid fuses are intended for the protection of 11 and 33KV pole or pad mounted transformers on rural systems and also for Spurs, feeding a number of transformers. The fuse has the glass tube which fills with carbon tetrachloride. The fuse element places inside the glass tube.

Do fuses have liquid in them?

The liquid inside the fuse is perchloroethylene, better known as “dry-cleaning fluid,” with a colorant so that you can see the level.

What is HFC fuse?

Definition: HRC fuse (high rupturing capacity fuse) is one kind of fuse, where the fuse wire carries a short circuit current in a set period. If the fault occurs in the circuit then it blows off. The HRC fuse is made with glass otherwise some other kind of chemical compound.

What are the four types of fuse?

Different Types of Fuses – Constriction, Working & Characteristics

• DC Fuses.
• AC Fuses.
• Cartridge Fuses.
• D – Type Cartridge Fuse.
• HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
• High Voltage Fuses.
• Automotive, Blade Type & Bolted Type Fuses.
• SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.

What is liquid type HRC fuse?

The liquid type HV HRC fuse is mostly used in the high voltage circuit. It is used for the transformer protection or for the circuit having a rating higher than 400A. The fuse has the glass tube which fills with carbon tetrachloride. The fuse element places inside the glass tube.

What is the liquid in a fuse box?

The liquid inside the fuse is perchloroethylene, better known as “dry-cleaning fluid,” with a colorant so that you can see the level. The installation instructions for the fuse suggest that you “avoid contact of liquid with red-hot surfaces […].”

What is the function of a power fuse?

Fuses are the protectors, these are the safety devices which are used to protect the home appliances like televisions, refrigerators, computers with damage by high voltage.

What is the replacement for liquid filled fuses?

For the most part, the liquid-filled fuses have been replaced by a modern, liquid-free version, the boric acid expulsion fuse ( example ). These work in a similar fashion— just without the liquid. A heavy spring is held taut by a fusible silver element.

What is the difference between a garden fuse and a liquid fuse?

The big difference between that little fuse and our liquid-filled monstrosity here is that while the “garden variety” one is rated for a modest (but still potentially lethal) 250 V, the liquid-filled fuse is rated for 23 kV at 15 A.
