Abstract
The utility model relates to an electronic A-type after-current action breaker having a permanent magnet tripper and belongs to a leakage breaker. The breaker comprises a handle, a release link, a push rod, a transmission connecting rod, a tripping rod, a moving contact separating mechanism, an electronic element board, a permanent magnet tripper, and a lock rod. The utility model is characterized in that the power consumption is low, the volume is small, the primary power supply can be cut off quickly when the power grid voltage is in fault and the breaker can reliably pass EMC test.
Description
Technical field
The utility model relates to a kind of residual current circuit breaker, particularly a kind of A type residual current action breaker of electronic type band permanent magnet releaser.
Background technology
The electronic type residual current action breaker (residual current circuit breaker) of people's use at present, its holding function is relevant with line voltage, in case line voltage breaks down, residual current circuit breaker does not just have protective effect.
Notification number CN201178296Y that Patent Office of the People's Republic of China is authorized and CN201360136Y patent have reached and have solved this hidden danger, but exist: 1, power consumption height; 2, the circuit breaker break-time is long when the supply voltage fault; 3, the poor reliability during verifying electromagnetic compatibility (EMC).
The utility model content
The utility model is to overcome above defective, the technical scheme that adopts is a kind of A type residual current action breaker of electronic type band permanent magnet releaser, comprise: handle 1, kinematic link 4, moving contact deciliter mechanism 6, described handle 1 and moving contact deciliter mechanism 6 usefulness kinematic links 4 are linked, one end of described release lever 5 cooperates with an end of locking-bar 9, the other end of release lever 5 cooperates with moving contact deciliter mechanism 6, locking-bar 9 and release link 2 are coaxial equipped, one end of release link 2 is between the push rod external part of the other end of locking-bar 9 and permanent magnet releaser 8, be provided with push rod 3 between the other end of release link 2 and the moving contact deciliter mechanism 6, permanent magnet releaser 8 is connected with the electronic component plate.
The utility model advantage is low in energy consumption, and is simple in structure, and volume is little, and breaking speed is fast, stability and good reliability.
Description of drawings
Fig. 1 is the A type residual current action breaker separating brake schematic diagram of the utility model electronic type band permanent magnet releaser.
Fig. 2 is the A type residual current action breaker combined floodgate schematic diagram of the utility model electronic type band permanent magnet releaser.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
Shown in Figure 1, when residual current circuit breaker was in gate-dividing state, the A point left side of moving contact deciliter mechanism 6 was cut out face release lever 5 and push rod 3 is pushed away left simultaneously, and release link 2 makes permanent magnet releaser 8 push rods stretch under the effect of push rod 3, permanent magnet releaser 8 is in closure state, and makes locking-bar 9 toward release lever 5.
Shown in Figure 2, when residual current circuit breaker is in "on" position, the A point left side of moving contact deciliter mechanism 6 is cut out and is moved towards the right, make between the left sanction face of A point of push rod 3 and release lever 5 and moving contact deciliter mechanism 6 and produce the space, when main power source residual current or line voltage occur and breaks down, electronic component plate 7 gives permanent magnet releaser 8 energisings, permanent magnet releaser 8 gets electric release push rod and stretches out 5 releases of promotion locking-bar 9 release levers, the 6 action separating brake outages of moving contact deciliter mechanism, face is cut out simultaneously push rod 3 and release lever 5 reduction in the A point left side of moving contact deciliter mechanism 6, and residual current circuit breaker is in gate-dividing state.
