Introduction
Circuit Breakers is an essential device in our electrical power system, and 3120-F32K-P7T1-W14DR3-6A is one type of them. This article will discuss the application field and working principle of 3120-F32K-P7T1-W14DR3-6A circuit breaker.
Application Field of 3120-F32K-P7T1-W14DR3-6A Circuit Breaker
3120-F32K-P7T1-W14DR3-6A circuit breaker is a high voltage isolating switch, suitable for sections switching and insulation in power systems with AC voltage up to 40.5 KV. It is widely used in power distribution systems, to limitation of fault current, capacitance current, overload current, reverse current and voltage. Non-sinusoidal AC current such as inverter power of frequency inverter and temporary outgoing from UPS can also be blocked by 3120-F32K-P7T1-W14DR3-6A circuit breaker, besides switching on and off circuit in normal condition.
Overcurrent protection devices such as circuit breaker should not be connected directly with communication signals and zero line, so that the possible communication interference signals can be avoided. Therefore, in the modern integrated electrical power control system, the 3120-F32K-P7T1-W14DR3-6A circuit breaker can be applied in the section switching devices of power distribution and the power generation system Automation devices.
Working Principle of 3120-F32K-P7T1-W14DR3-6A Circuit Breaker
3120-F32K-P7T1-W14DR3-6A circuit breaker is a type of high voltage switchgear device for breaking and making high voltage circuits. The circuit breaker consists of breaker arc extinguishing chamber, support spring and fixing bracket etc. conducted by the drive mechanism and under the drive of piston or spring, the circuit breaker can break or close the power supply.
When the load current and short circuit current is over the rated current of the breaker, the thermal relay in the drive mechanism will be operated, thus the breaker is opened by releasing the drive mechanism. The movement of the breaker is driven by the electromagnetic force in its interior.
When the current reaches its rated current, correspondingly the current in the electromagnet increases and form the electromagnetic repulsion force, then the movement of the circuit breaker is completed. The breaker arc arises between contacts when the circuit breaker is opened due to the current of the electric arc, meanwhile, it is removed by arc extinguishing medium in the arc chamber.
When a fault occurs, the circuit breaker should be used to break the power in a very short period of time, which could prevent the further spread of the fault current.
Conclusion
The application field and working principle of 3120-F32K-P7T1-W14DR3-6A circuit breaker has been introduced in this article. The 3120-F32K-P7T1-W14DR3-6A circuit breaker is a high voltage isolating switch, which is widely used in power distribution systems. Its working principle is driven by the electromagnetic force, and when the load current over the rated current, the circuit breaker will be opened. That is all for the introduction of 3120-F32K-P7T1-W14DR3-6A circuit breaker\'s application field and working principle.
