Circuit breakers are essential pieces of equipment used in power grids all around the world, but few people know the technical details behind their operation. The LELK1-1RS4-30452-15 is one example of a modern circuit breaker, and this article explains how it works and the field in which it can be used.

Introduction

When a power system experiences an overload or surge in power, it must be protected from the sudden rise in electricity, or serious damage to components downstream or even fires on the premises can occur. That\'s where circuit breakers come in as they provide a way to automatically detect system overloads or faults and open the circuit, thus protecting the system.
Circuit breakers range from the most basic of devices that detect a single point of failure to sophisticated systems that can monitor an entire network for systems disturbances. The LELK1-1RS4-30452-15 is one example of a modern circuit breaker, developed by Siemens, which provides reliable protection for medium voltage networks.

Application Field

The LELK1-1RS4-30452-15 is designed for use in medium voltage networks that have an operating voltage range of 6-24kV and a rated current of 160A. It is suitable for a variety of different applications, including small utility power plants, distribution cabins and substations. It is also suitable for use in the mining and oil and gas industries, as well as other power-intensive applications.

Working Principle

The LELK1-1RS4-30452-15 is a vacuum circuit breaker, which works by using an arc-quenching gas to extinguish any electric arcs that may form as the breaker is opened or closed. When the breaker is closed, the movable contacts make contact with each other and the electric current flows through the breaker, enabling power to be supplied to downstream components. When the breaker is opened, the movable contacts move apart and the electric arc is quickly extinguished by the arc-quenching gas. This ensures that the breaker can be opened quickly and safely without damaging the contacts.

The LELK1-1RS4-30452-15 is designed to have a high short-circuit breaking capacity of 25.2kA and a short-circuit making capacity of 25kA, as well as a fast breaking time of less than 0.13 seconds. This ensures that the breaker can be operated quickly and efficiently in the event of an overload or system fault. Additionally, the breaker is designed with a high mechanical endurance at up to 6,000 operations.

Conclusion

The LELK1-1RS4-30452-15 is a modern and reliable circuit breaker, designed for use in medium voltage networks. It has a high breaking and making capacity, as well as a fast breaking time and can be used in a variety of different applications. It provides reliable protection for electrical systems and is an effective way to protect systems from overloads and faults.
