What are the advantages of the DC Molded Case Circuit Breaker?
First of all, the DC Molded Case Circuit Breaker has a very good application in the power system. Especially in some power plants or substations, it is widely used. Because these areas have large-capacity and high-voltage power systems. The applied DC system generally provides a very reliable power supply for relay protection and control operations. The importance of the small device is needless to say for the corresponding DC system. The DC Molded Case Circuit Breaker can ensure the safety of the power system to the greatest extent.
What is the difference between a DC Molded Case Circuit Breaker and an AC molded case circuit breaker?
The difference between a DC Molded Case Circuit Breaker and an AC circuit breaker is the ability to extinguish the arc. Since each cycle of the exchange has a zero-crossing point, it is easy to extinguish the arc at the zero-crossing point, while the DC switch has no zero-crossing point, and the ability to extinguish the arc is very poor, so it is necessary to add a rated In general, it is difficult for DC to extinguish the arc, and the exchange has zero-crossing, and the arc is easy to extinguish.
A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions, and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use.
What are the uses of DC Molded Case Circuit Breaker in daily life?
1. DC power supply:
DC Molded Case Circuit Breaker is widely used in communication power supply, EPS, UPS and other DC power supplies in the information industry
2. Rail transit and electric locomotives:
At present, the urban rail transit system is powered by DC system. The DC Molded Case Circuit Breaker for rapid analysis is an important component in rail transit.
3. Ships:
DC Molded Case Circuit Breaker is one of the very important components in ship power system and electric propulsion system. It protects the failure of the power distribution system and electrical equipment to ensure the safety of the ship's power supply system and electrical equipment.
Zhejiang Shilong Electric Technology Co., Ltd has worked for several years to meet the need of customers from the world. They can create a 24-hour engineering and development environment for DC Molded Case Circuit Breaker production.
