Introduction to LELK1-31818-15

The LELK1-31818-15 is a type of medium voltage circuit breaker manufactured by Lublin Electric Co. Ltd. It is a three-phase, air-break type of circuit breaker which can be used to control and protect the distribution equipment up to a voltage of 15 kV. Additionally, the LELK1-31818-15 can be used for electrically isolated networks, where a main and secondary network are isolated from each other, but still connected. It is well-suited for distribution transformer protection, as well as for distribution line protection.

Application Field of LELK1-31818-15

The LELK1-31818-15 circuit breaker can be used in a variety of applications. It is suitable for a wide range of power supplies, including alternating current (AC) and direct current (DC). This includes systems where the power supply is three-phase or single-phase. It is suitable for low, medium and high voltage systems. It is also suitable for electrical networks which are completely isolated from each other. Furthermore, it is suitable for utility and telecommunication systems, as well as for industrial, commercial and residential applications.

Working Principle of LELK1-31818-15

The LELK1-31818-15 is a type of circuit breaker which employs the arc quenching technique in order to break the circuit. The mechanism works by using an arc which is created when the contacts of the circuit breaker open. The arc is then extinguished by the use of air and gas which is forcibly in-rushed into the arc. This is known as the air-break process. The air-break process works to quickly dissipate the energy produced by the arc. This is done by forcing the arc to move away from the contact surfaces. At the same time, the air in-rushed into the arc helps to cool the electrodes. As the arc cools down, the vaporized material solidifies and the arc is extinguished. The LELK1-31818-15 can be used for both slow and rapid operation. The slow operation helps to reduce the contact wear, while the rapid operation helps to quickly disconnect the circuit in the event of a fault.

Advantages

The LELK1-31818-15 provides many advantages to users. It has a number of features which make it highly reliable and suitable for a variety of applications. It has a safe and efficient operation, as the air-break process helps to quickly extinguish the arc. Additionally, it has a high breaking capacity and low operating current. This means that it can safely break even large currents. The LELK1-31818-15 is also highly reliable and easy to maintain, as it has a long life expectancy and low maintenance requirements.

Conclusion

The LELK1-31818-15 is a type of medium voltage circuit breaker which can be used for a variety of applications. It employs an air-break process in order to quickly break the circuit. This process helps to reduce the contact wear and protect the circuit from damage. Additionally, the LELK1-31818-15 provides a number of advantages, such as a high breaking capacity, low operating current and a reliable, long-lasting operation.
