In this article, we will discuss in detail the application field and working principle of the IULHB11-35040-40 circuit breaker.

IULHB11-35040-40 Application Field

The IULHB11-35040-40 circuit breaker is a type of high-voltage switchgear, and its application fields have been widely used in various industrial and commercial power systems. The rated voltage of this circuit breaker is up to 40.5 kilovolts and the rated current up to 4000 amperes. It is suitable for load breaking, line isolation and line opening/closing operations in three-phase AC power systems. It can also be used in distribution networks, industrial and mining power systems, energy storage systems, photovoltaic systems and electric vehicle charging systems.

Furthermore, its features, such as easy and convenient installation, small size and flexible connection mode also increase its widespread popularity. It is equipped with diagnostic functions and can be connected to the remote monitoring systems for online monitoring of its switchgear, ensuring the over-voltage, under-voltage, phase imbalance and earth leakage protection of the power system.

IULHB11-35040-40 Working Principle

The IULHB11-35040-40 circuit breaker is usually composed of a arc extinction chamber, a main operating mechanism, a cylinder containing gas, an operating switch, a pressure adjusting device, an arc extinction auxiliary switch and an adjustable closing mechanism. When the switch is triggered, the arc extinguishing chamber is filled with a gas that can quickly block the arc within the chamber. The main operating mechanism is controlled by a handle, which can switch the circuit breaker ON/OFF. When the switch is in the ON position, the electrical contact is connected and the circuit is allowed to flow currents.

The pressure adjusting device is used to control the pressure of the gas. The higher the pressure, the faster the circuit breaker can close or open the circuit. Moreover, the adjustable closing mechanism can be adjusted to a different speed, which allows more flexibility for the circuit breaker to adjust for different situations. In addition, the arc extinction auxiliary switch can be used to create a dead period between the activation and activation time, thus providing an additional level of security to the circuit.

Conclusion

In conclusion, the IULHB11-35040-40 is an efficient circuit breaker with wide application fields and advanced protection functions. Its working principle is also well designed, which provides the circuit breaker with ultimate security and reliability. Therefore, the IULHB11-35040-40 is an ideal choice for various industrial and commercial power system.
