Arc Splitter In Circuit Breaker

In order to avoid that the arc has to be safely and effectively extinguished.

Arc splitter in circuit breaker.

Air blast circuit breaker may be a single blast or double blast. A common arc control scheme used in many circuit breaker designs i e. The conduction of electric charges through gas produces plasma which glows. Here is the image of the arc chute.

The splitters increase the length of the arc even further. An electric arc is the discharge of electric current through gas or air. Electric arc produces heat that can melt the contacts of the breaker and even damage the circuit breaker itself. Circuit breaker which features a unique and innovative patent pending arc quenching configuration that allows the breaker to safely handle high amperage and high dc voltage applications in a compact package.

A 3 d simulation model of air arc plasma in a low voltage circuit breaker considering the production of iron vapor from splitter plate erosion is developed. The thing that you are asking is known as arc chute. Acb for example a miniature circuit breaker mcb. These arc splitter plates are also called arc chutes where arc is formed into a series of arcs and at the same time energy extracted and cools it.

Types of miniature circuit breakers mcb s. When the current is greater than 100a these gases get dissociated into atoms which changes the characteristics of the arc on account of the associated change in its thermal conductivity. The arc in the air circuit breaker runs in a mixture of nitrogen oxygen and copper vapour. Arc chute is used in low voltage circuit breakers or in air circuit breakers i e.

Axial blast air circuit breaker in the air blast circuit breaker the flow of air is longitudinal along the arc. By using a patent pending magnetic flux boosting terminal configuration a strong magnetic field is created. A typical arc baffle structure in a small circuit breaker is shown in figure 5 9. A method used to increase the total arc voltage across the main contacts is to force the arc into an arc baffle or splitter structure.

The air blast circuit breakers according to the type of flow of blast of compressed around the contacts are of three types namely axial radial and cross blast. The distributions of temperature and.
