Abstract
The utility model discloses a novel structure of a circuit breaker instantaneous tripper, which has the characteristics that: a fine tuning base is arranged on a yoke, and a fine tuning screw is arranged on the fine tuning base, and an armature pressure plate is additionally arranged on the armature, in the way, when the circuit breaker checks short circuit, the fine tuning screw can be rotated, so as to change the gap of the armature and the iron core, lead the short-circuit tripping value of the instantaneous tripper to be controlled in a small error range and effectively improve the short circuit protective performances of the circuit breaker.
Description
Technical field:
The utility model relates to a kind of circuit breaker instantaneous release new construction, and it is the improvement to existing mold cased circuit breaker instantaneous release.Belong to low-voltage electrical apparatus manufacturing technology field.
Background technology:
Existing breaker of plastic casing instantaneous release as shown in Figure 1, it mainly is made of armature 1, yoke 2, coil 3, unshakable in one's determination 4, axle 5, spring 6, conductive plate 7, its effect is to make circuit breaker tripping device separating brake.When circuit breaker is in "on" position, circuit outlet short trouble, produce electromagnetic attraction with armature 1 and 4 adhesives unshakable in one's determination, armature 1 is rotated to an angle after, the draw bar of bump circuit breaker reaches the purpose of dropout separating brake.This instantaneous release owing to the error of part manufacturing, can't carry out reasons such as fine adjustments, makes the short-circuit current value of instantaneous trip very unstable, thereby causes short circuit dropout protection value error range bigger, influences the short-circuit protection performance of circuit breaker.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of rational in infrastructure, and can effectively dwindle the circuit breaker instantaneous release new construction of circuit breaker short circuit protection value error range.
For achieving the above object, the utility model has been taked following measure:
The utility model has improved the structure of yoke, on yoke, is provided with a fine setting seat, on the fine setting seat, is provided with micrometer adjusting screw; Simultaneously; on armature, be equipped with the armature pressing plate; like this; when circuit breaker carries out short-circuit calibration; can rotate micrometer adjusting screw; can change the gap between armature and the iron core, the short circuit drop-away value of instantaneous release is controlled in the very little error range, thereby effectively improve the short-circuit protection performance of circuit breaker.
Description of drawings:
Fig. 1 is the structure of existing circuit breaker instantaneous release
Fig. 2 is a structural representation of the present utility model
Wherein: 1-armature 2-yoke 3-coil 4-5-pivot pin unshakable in one's determination 6-spring 7-conductive plate 8-micrometer adjusting screw 9-fine setting seat 10-armature pressing plate
Embodiment:
A kind of circuit breaker instantaneous release new construction described in the utility model includes parts such as armature 1, yoke 2, coil 3, unshakable in one's determination 4, axle 5, spring 6, conductive plate 7, on yoke 2, is provided with a fine setting seat 9, on fine setting seat 9, is provided with micrometer adjusting screw 8; Simultaneously; on armature 1; be equipped with armature pressing plate 10; like this; when circuit breaker carries out short-circuit calibration, can rotate micrometer adjusting screw 8, can change the gap between armature 1 and unshakable in one's determination 4; the short circuit drop-away value of instantaneous release is controlled in the very little error range, thereby has effectively improved the short-circuit protection performance of circuit breaker.
