Fuses: BK/AGC-3-2/10 Application Field and Working Principle

Fuses are an important protective component in electrical systems and are used in various fields. The BK/AGC-3-2/10 fuse, in particular, is one of the most popular fuses used in the solar photovoltaic industry. This article will provide a detailed description of the application field and working principle of the BK/AGC-3-2/10 fuse.

Application field of BK/AGC-3-2/10 fuse

The BK/AGC-3-2/10 fuse is one of the most popular high-voltage fuses in the solar photovoltaic industry. It is used for string photovoltaic systems with DC output voltages of up to 1000V. The fuses are usually installed at the junction box of each string of photovoltaic cells, and provide overcurrent protection for string circuits. It is suitable for use with photovoltaic modules rated up to 1000V and currents up to 2A. Apart from solar photovoltaic applications, this fuse may also be used for other applications where overcurrent protection with low DC voltage is required.

Working principle of BK/AGC-3-2/10 fuse

The BK/AGC-3-2/10 fuse is a low dropout fuse used in the solar photovoltaic industry. It is a thermal cutoff device that uses a thermal element to protect circuits against overcurrent. The thermal element in the fuse is designed to open the circuit as soon as the current reaches a certain level. As the current increases, the element heats up and is eventually opened by its own temperature rise. This type of fuse is designed to operate at a lower current rise than other types of fuses, meaning that it can protect the circuit even at lower overcurrent conditions.

When the BK/AGC-3-2/10 fuse is used in a photovoltaic system, it is usually placed in series with the circuit. As the current increases, so does the voltage drop across the fuse. This will result in the voltage at the load being lower than the rated voltage, increasing the efficiency of the system. If a short circuit or an overcurrent occurs, the fuse will detect it and open the circuit, protecting the rest of the system from any possible damages.

Conclusion

The BK/AGC-3-2/10 fuse is a popular high-voltage fuse used in the solar photovoltaic industry. It is suitable for use with photovoltaic modules rated up to 1000V and currents up to 2A. The fuse operates using a thermal element that opens the circuit when the current reaches a certain level. It provides overcurrent protection for string circuits and increases the efficiency of the system by reducing the voltage at the load.
