What are the applications of fuse?
Fuse Applications
- Used to protect transformers, motors and power system from over-current conditions.
- In feeders, power transformers, and solar circuits.
- Electrical appliances and house distribution boards use fuse for domestic purposes.
- Used in automotive cars, electric vehicles, racing cars, rails.
What is the working principle of HRC fuse?
Working Principle Of HRC Fuse As element melts it vaporized and scattered, as arc form the chemical reaction between element vapor and quartz powder, forming high resistance substance which helps in quenching the arc thus fault current interrupts.
What is HRC cartridge fuse?
An HRC fuse is a type of cartridge fuse, in which the fuse element is enclosed within a transparent capsule, usually made up of steatite–a ceramic material having good mechanical strength. Manufacturers are now using epoxy resins instead of ceramic material. The capsule is provided with two end caps.
What type of fuse is used in most low current applications?
Rewirable
Rewirable or Kit – Kat Type Fuses are a type of Low Voltage (LV) Fuses. They are most commonly used in house wiring, small industries and other small current applications. Rewirable Fuses consists of two main parts: a Fuse Base, which contains the in and out terminal, and a Fuse Carrier, which holds the Fuse Element.
What are HBC fuses?
High breaking capacity (HBC) fuse is today one of the most used low and medium voltage protective devices. These fuses, in general are not able to break any current that begins the melting process. An introduction about the HBC fuse design characteristics and operation modes is given.
Which powder used in HRC fuse?
Also, constrictions in the fuse element are provided which play a very vital role in the operation of Fuse. The space between the body surrounding the Fuse element is filled filling powder such as with Silica Send, Chalk, plaster of peris etc.
What is the use of a fuse with a HRC fuse?
HRC Fuse is kind of fuse wire that carries short circuit large current for a defined period. If the fault, during this time is removed, it stays intact. On the other hand, if the error persists, the fuse blows off or melts quickly. Its applications include:-
What is a high rupturing capacity fuse?
HRC Fuse (High Rupturing Capacity Fuse) and its Types This type of fuse contains a fuse wire in it, which carries the short circuit current safely for a given time period. During this period, if fault is removed, then it does not blow off otherwise it will melt and remove the circuit from electrical supply hence, the circuit remains safe.
Why do we use a fusefuse?
Fuse is used in electrical circuits only to prevent this defect. Thus a copper wire is used when if the current exceeds its capacity it melts and further the working device overload from it is saved from loss of views. There are so many types of fuss in the market today we have to talk.
What is the use of a short circuit protection fuse?
It is used for short circuit protection in medium voltage (up to 33KV) and low voltage (up to 400V).. In modern this type fuse (HRC) provides reliable discrimination and accurate characteristics. • It is used in meter board in residential application. It is also protected different electrical device as like that.
