33kv 35kv THREE PHASE Automatic Circuit Recloser ACR

The AB-3S series circuit reclosers are recently-developed pole-mounted intelligent vacuum circuit reclosers of a new generation, which absorb the advanced domestic and foreign technologies adopted by our company, embody the design concept of being "intelligent, energy-saving, environemntally-friendly and maintenance-free". This product integrates such functions as control, protection, measurement, fault positioning, online monitoring and synchronous closing. With full functions and high digitalized and intelligent degree, they are top choices for equipment of power distribution network automation and intellectualization process.

This product conforms to IEC60044-1, IEC60060, IEC60068-2, IEC60099-4, IEC60255-27, IEC60270, IEC60280.1, IEC60529, IEC60694, IEC60815-1, IEC60870-5-101, IEC61000-4, IEC61243-5, IEC62271, standards, etc.

 Major Technical Parameters are shown below:
 
Our advantages:
1. Most parts are manufactured ourselves, like: frame, cabinet, permanent magnet mechanism, insulation part, control panel, etc. That means the process quality control is effectively controlled.
2. Adopt fast algorithm with national patent technology (patent number: ZL200720037710.7) so as to obtain fast breaking capacity of circuit breaker. As a result, it can isolate fault circuit rapidly. It takes less than 25ms from inspecting fault to cut fault circuit by separate circuit breaker. It can avoid the problem of override trip effectively.
3. Adopt single phase earthing protection system with national patent technology (patent number: ZL201020178325.6). It can realize on-line judgment to single phase earthing fault of low current earthing system without adding device. Releases warning or tripping action according to setting value
