/> < bb br Number of parts
bb The permanent magnet mechanism is mainly composed of the following parts:
, opening spring: it provides energy for opening
, non-magnetic backing plate: adjusting the stroke< br/> , permanent magnet:
, static iron core: forming a magnetic circuit
, coil
, moving iron core: realizing movement
, driving rod: making the arc extinguishing chamber realize relative movement< br/> bb The traditional spring mechanism has more than one various parts
< bb br Action characteristics
bb adopts a patented three-single-phase monostable permanent magnet operating mechanism, with only one movable part. Up and down linear motion, low power consumption, can realize the opening and closing function of the end position of the mechanism, short reaction time, and high action reliability.
bb The spring mechanism has more than one component, many transmission components, the structure is complex and unstable, the mechanism wear can easily lead to operation failure, and there are many failure points.
< bb br Action time
bb The inherent action time of the permanent magnet mechanism is only
, the online detection and judgment time is only
~
, and the entire switch group action time is only
/> ~
bb The action time of the spring mechanism is generally ~, and the action time of the entire group is generally ~
< bb br Action principle
bb Electromagnetic closing, spring opening, permanent magnet holding
bb The energy storage of the spring and the release of the spring energy by the energy storage motor
< bb br Mechanical life
bb The permanent magnet mechanism can reach the sub-mechanical life action test, but the industry recognizes that the number of actions of the permanent magnet mechanism can reach Thousands of times.
bb The spring mechanism generally reaches the sub-mechanical life test.
< bb br Mechanical
Tripping device
bb The permanent magnet mechanism can realize the opening and closing function of the circuit breaker without a tripping device
bb The spring mechanism has a mechanical tripping device , high power consumption and low reliability
