Circuit breakers are essential components in any power system. They are used to protect against overvoltage, overcurrent and short circuits. 1C6UL is an encapsulated outdoor high voltage circuit breaker. It is a type of air blast circuit breaker which operates at a relatively high voltage level. This article will discuss the 1C6UL application field and working principle.

The 1C6UL circuit breaker is mainly used in 220 kV and 500 kV power system. It can also be used in overhead line and transformer substations. It is also used as a protection device in power plants, substations, urban power grids and industrial parks. The 1C6UL is designed to protect against both current faults and overvoltage conditions. It is also designed to provide safe operation and reliable protection in harsh environments.

The 1C6UL circuit breaker is an air blast breaker. It uses compressed air to open and close the circuit. The breaker uses a pneumatic cut-off system to rapidly and effectively open the circuit. The compressed air is stored in a tank and then released when the breaker is tripped. This rapidly opens the arc chamber and brings the electrical circuit to a safe state.

The 1C6UL breaker operates according to a four-stage sequence: interruption, short-circuit back-up, arc-extinction and contacts-charging. In the interruption stage, the arc is initially extinguished and the contacts are opened. In the short-circuit back-up stage, the contacts close and transfer the current from the breaker contacts to the circuit breaker contacts. In the arc-extinction stage, the arc is extinguished by the compressed air and the contacts are opened. In the contacts charging stage, the arc is extinguished and the contacts are closed.

The 1C6UL is designed so that it can be operated manually or electronically. The manual operation is done by pushing a button which activates the tripping mechanism. The electronic operation is done using a relay. The relay is connected to the tripping mechanism and when a fault is detected, the relay sends an electrical signal which activates the tripping mechanism. The relay can be programmed to detect different types of faults and tripping times can also be adjusted.

The 1C6UL is a reliable air blast circuit breaker which can provide safe and effective protection in high voltage applications. It is designed for long-term use in difficult operating conditions and can ensure reliable protection. It is also easy to operate and maintain due to its simple design. The 1C6UL is a reliable and cost-effective choice for power systems.
