YUANKY indoor permanent magnetic Vacuum circuit breaker 12-24 KV 630A 1600A 3150A VCB

Short Description:

This products use permanent magnetic mechanism for the operation , rated voltage 12KV, rated frequency 5OHZ, rated current 630A-3150A, short circuit current 16KA-4OKA. It can be directly used in KYN28 switch cabinet, without any change to the cabinet.

Technical features

This product is syncretized by several advanced technologies from vacuum, magnetic, itelligent control. Based on the original advantages of the ZN73 type indoor vacuum circuit breaker, it also have the below advantage: Advanced control technology and long service life.

As used the high performance permanent magnetic materials and the sophisticated microcomputer designed control, through our proprietary control technology, to adjust the driving power of the permanent magnetic coil, so that the breaker can reach the best open/close curve, and let the open/close end act as soft landing, drastically reduced the mechanical collision, improved the service life of the spare parts greatly. At the sarme time, it is avoided the change of the over-travelling and opening contacts caused by the mechanism deformation, which accumulated by the mechanical collision of the dynamic and static conductive rod during operating. And the user don’t need to do any change.

The performance of such circuit breaker has reached unprecedented heights in the industry, with a long service life of 20 years. During the operation in normal load current, no need any maintenance, adjustment and can be worked in frequently operation.shows its’ superiority characteristics.

Main technical parameters(12kv)

Simple Structure,High Reliability:

Adopting full new design of perrmanent magnetic operating mechanism,it has characteristics of big output force, light weight, easy operating and reliable operation.The quantity of spare parts is 90% less than the spring type mechanism. There are no any lock at opening and closing position. At closing position, permanent magnet uses the low magnetic impedance supplied from moving and static core to keep it at closing position. And at opening position , it keeps by opening spring. Simple mechanism transmission, vacuum chute contacts operating stable, without refusing opening or closing. and fault opening or closing.

Perfect Function:

Power adaptable, different external AC/straight through modern electric power by the controller The conversion of the source technology to make organizations work in the best eye-voltage conditions, the operating power of small Control Controller has a circuit breaker to provide the “anti-jump” , “ree trip” and complete “dosed Lock proltection” function. Upgrade the controller software can be “onlineprogramming” . making the controller Relay can easily meet the growing demand.

Facilitate communication

Standard communication in terface. to facilitate networking, remote data exchange. Can to the Central Circuit breaker controlroom sent all the information you can give and accept all the central contral room sent Kindsof instruction.

Anti-interference

Electromagnetic compatibility requirements to meet the national standard four, can avoid electromagnetic interference cited From the problem.
