Introduction

In the field of electrical engineering, circuit breakers are an essential component used to protect circuits from the effects of overloads, overheating, and current leakage. The 1D2UM circuit breaker is an advanced type of circuit breaker designed specifically for use in high voltage and high power applications, such as those found in power plants and factories. This article will explain the application field of the 1D2UM circuit breaker and its working principles.

Application Field

The 1D2UM circuit breaker is a high voltage and high current circuit breaker that is widely used in industrial applications. Specifically, it is suitable for the distribution of up to 15kV AC power and up to 600A short-circuit current in three-phase networks. It has excellent protection capabilities, even under extreme conditions such as high temperatures, strong electromagnetic fields, as well as fluctuating voltage. In addition, this high-end circuit breaker can also be used in other applications such as motor control, high speed railways, industrial automation, and so on.

Working Principle

The 1D2UM circuit breaker works on the principle of electromechanical separation, in which the breaker is composed of two main parts, the contacts and the arcing chamber. The contacts are responsible for connecting or breaking the circuit, while the arcing chamber is used to safely remove current and/or voltage surges that can damage the system. First, when current flows through the arcing chamber, it is interrupted by the air gap between the contacts and the arcing chamber, which is filled with insulating gas. The gas helps to reduce the voltage across the gap, allowing the current to pass without causing any damage to the circuits. Next, when a current surge or overload occurs, the contacts open up, breaking the circuit and preventing the surge from travelling further. In addition to breaking the circuit, the 1D2UM circuit breaker is also designed to detect the presence of a load on the circuit. When it senses a load, it automatically trips the breaker, thereby disconnecting the circuit and protecting it from damage. The circuit breaker is equipped with two detection systems: first, a thermal detection system; second, an electronic detection system. The thermal detection system senses the amount of current flowing, while the electronic detection system uses an electrode to detect the presence of a load.

Conclusion

The 1D2UM circuit breaker is a powerful, reliable, and versatile tool for protecting electrical circuits in high voltage and high current applications. It works on the principle of electromechanical separation, in which the breaker is composed of two main parts, the contacts and the arcing chamber. The contacts are responsible for connecting or breaking the circuit, while the arcing chamber is used to safely remove current and/or voltage surges that can damage the system. In addition, it is also equipped with two detection systems, a thermal detection system and an electronic detection system, to provide additional protection.
