Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 to Fig. 4, in the present embodiment, a kind of adjustable instantaneous characteristic for breaker of plastic casing it is de-
Buckle device includes mounting bracket 1, thermal element 2, yoke 3, armature 4, fixed seat 5, sliding seat 6 and spring 7, the He of thermal element 2
Yoke 3 is installed on the mounting bracket 1, and fixed seat 5, the fixation are provided with the side of the yoke 3 on the mounting bracket 1
The overall L-shaped structure of seat 5, the bottom of the fixed seat 5 is corresponding with the bottom of the mounting bracket 1 to offer fixing hole, fixes
Fixed seat 5 is fixed on the bottom of the mounting bracket 1 through both fixing holes by screw 8.
The two bottom sides of the fixed seat 5 are correspondingly arranged on hinged seat 9, and the two bottom sides of the armature 4, which are provided with, to be hinged
Correspondence offers hinge hole on portion 10, the hinged seat 9 and articulated section 10, and both are flexibly connected by steady pin 11, described
Armature 4 can be rotated along the hinged seat 9.
The sliding seat 6 freely up and down can be actively arranged in fixed seat 5 along fixed seat 5, the sliding seat 6 and fixation
The spacing hole 12 of strip is offered on seat 5 along the vertical direction, the spacer pin 13 is installed on the sliding seat 6 and fixed seat 5
On spacing hole 12 in sliding seat 6 is carried out in fixed seat 5 unidirectionally spacing, i.e., sliding seat 6 is along in the presence of spacer pin 13
Moved up and down along fixed seat 5.
The top of the fixed seat 5 is extended with contiguous block 14, the contiguous block 14 to side and offers adjustment hole, described
The top of sliding seat 6 is extended with adjustable plate 15 to side, and the adjustable plate 15 is located at the lower section of the contiguous block 14, branch head screw
16 one end is resisted against the end face of the adjustable plate 15 through the adjustment hole, and regulation branch head screw 16 can promote the edge of sliding seat 6
Fixed seat 5 is moved up and down, and nut is installed on branch head screw 16 after regulating, to ensure that it will not loosen.
The bottom of the sliding seat 6 is extended with the first spring coupling part 17 to side, and the top of the armature 4 is to close to sliding
The side of dynamic seat 6 is extended with second spring connecting portion 18, and the two ends of the spring 7 are connected to first spring coupling part
17 and second spring connecting portion 18 on.
When fault current is by thermal element 2, yoke 3 can produce magnetic force, attract armature 4, armature 4 is overcome spring 7
Pulling force, the hinged seat 9 around fixed seat 5 rotates, during rotation, and can hit draw bar makes circuit breaker tripping,
So as to reach the effect of instantaneous protection.
Because spring 7 is linked up with armature 4 and sliding seat 6, the regulation force value of spring 7 only needs to twist branch head screw 16
.By adjusting the path increment of branch head screw 16, to promote the upper and lower displacement that sliding seat 6 is carried out, exist so as to have adjusted hook
The length of the spring 7 of armature 4 and sliding seat 6, so as to have adjusted the force value of spring 7, carries out the wink dynamic regulation of electrical apparatus release.
Above example is the general principle and characteristic for elaborating the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
