Air circuit breaker

タイトルまたは説明

The rated power of SMW1(DW*5) Series Intelligent All-Purpose Type Circuit Breaker(referred to as circuit breaker hereinafter)is kind of breaker with AC *0Hz, **0V, or **0V, and its rated current is xxxxx is mainly used in power distribution network to allocate electric power and protect the line and supply equipment against overload, under voltage, short circuit, single phase grounding fault, xxxxx core part of the circuit breaker adopts intelligent type dropout device, which bears accurate alternative protection performance and can avoid unnecessary power failure, thus improve the reliability of power supply. Structure Character The product has two types of structure, namely, fixed type, which is mainly composed of contactor part, intelligent drop-out device, manual operation mechanism, electric operation mechanism, electric operation mechanism and drawer base. The circuit breaker is placed in three-D pattern and is characterized by its tight structure and small xxxxx contactor part is sealed in the insulation bottom plate, and contactors of every phase are separated with insulation board, hence several little chambers;while the intelligent dropout device, the manual-operation mechanism, and the electric operation mechanism are arranged before it in good order and form independent unit xxxxx case one of the units is damaged, it can be dismounted wholly to fix a new one.Among which: xxxxx part:AS one-step contactor is adopted, operating strength of the contactor is reduced because of the omitting of arc contactor transfer process, and the breaking process of short-circuit current is therefore xxxxx order to reduce the electric repelling force among contactors and improve the electric stability of the contactor part, the contactor part adopts multi-way parallel connection.
