Description
Technical field
The present invention relates to a kind of balanced controls, especially a kind of balanced controls of the impact resisting vibrating for magnetictrip.
Background technology
Along with the development of electric utility, moulded case circuit breaker operation mechanism becomes the main flow of current development gradually, designs to miniaturized, intelligent direction development.Breaker of plastic casing is all contained in a plastic casing by contact, arc control device, release and operating mechanism etc., is applicable to the protection switch making branch road.As shown in Figure 1, existing release adopts magnetictrip usually, comprise the electromagnet spring 1 be arranged in support 1, electromagnet assembly 2, electromagnetic trip assembly 3 and dropout push rod 4, electromagnet assembly 2 is energized, electromagnetic trip assembly 3 overcomes electromagnet spring 1, clashes into the trip point position of dropout push rod 4, dropout push rod 4 is rotated along installation shaft 4-1, device is threaded off, realizes its function.
As its performance of naval vessel motor-operating mechanism except the basic function meeting motor-operating mechanism, also should tolerate the mechanical environment residing for naval vessel and weather environmental requirement, as impact resisting vibrating requirement.The traditional method realizing impact resisting vibrating is the confining force strengthening release spring or mechanism, and this method of curing the symptoms, not the disease often need the volume increasing operating mechanism, and reliability is poor simultaneously.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of balanced controls of the impact resisting vibrating for magnetictrip be provided, this mechanism structure is simple, dependable performance, improve the impact resisting vibrating of mechanism.
According to technical scheme provided by the invention, a kind of balanced controls of the impact resisting vibrating for magnetictrip, described balanced controls are arranged on the support of electromagnetic trip assembly side, comprise and push away pendulum, pressing plate, balance plate and spring, it is characterized in that: on balance plate, fix the first joint pin, support above the first joint pin is fixed the second joint pin, linking springs between the first joint pin and the second joint pin; Install pressing plate in the below of described balance plate, press plate rotary is connected on support; The described pendulum that pushes away is arranged on the axle head of the installation shaft of dropout push rod, and lay out the push and block face of setting pushing away, push and block face contacts with pressing plate.
Described second joint pin is directly over the first joint pin.
The present invention has the following advantages: structure is simple, dependable performance, and mechanism takes up room little; Easy to manufacture, cost is low; In normal state, its basic function is not affected; Adopting equilibrium principle to make actuating mechanism consistent with this balanced controls inertia when being subject to impact shock, fundamentally solving the failure mechanisms problem because impact shock causes; Avoid mechanism because anti-impact vibration and the produced limitation that lost efficacy, add the scope of application of mechanism.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the stress balance schematic diagram of impact resisting vibrating of the present invention
Embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 1 and Figure 2: the balanced controls of the described impact resisting vibrating for magnetictrip comprise electromagnet spring 1, electromagnet assembly 2, electromagnetic trip assembly 3, dropout push rod 4, installation shaft 4-1, push away pendulum 5, push and block face 5-1, pressing plate 6, balance plate 7, first joint pin 7-1, the second joint pin 7-2, spring 8, support 9 etc.
As shown in Figure 1, balanced controls of the present invention are arranged on the support 9 of electromagnetic trip assembly 3 side, comprise and push away pendulum 5, pressing plate 6, balance plate 7 and spring 8, balance plate 7 is fixed the first joint pin 7-1, support 9 directly over the first joint pin 7-1 is fixed the second joint pin 7-2, linking springs 8 between the first joint pin 7-1 and the second joint pin 7-2; Install pressing plate 6 in the below of described balance plate 7, pressing plate 6 is rotatably connected on support 9; Describedly push away the axle head that pendulum 5 is arranged on the installation shaft 4-1 of dropout push rod 4, arrange push and block face 5-1 pushing away on pendulum 5, push and block face 5-1 contacts with pressing plate 6.
Operation principle of the present invention and the course of work: in normal state, balance plate 7, under the effect of spring 8, is in static, is relatively independent with pressing plate 6, does not affect the normal work of miscellaneous part; Electromagnet assembly 2 is energized, and electromagnetic trip assembly 3 overcomes electromagnet spring 1, clashes into the trip point position of dropout push rod 4, dropout push rod 4 is rotated; Fixedly mount because push away pendulum 5 with dropout push rod 4, as shown in Figure 2, dropout push rod 4 with push away pendulum 5 and can be considered Same Part, and around axle central rotation; Dropout push rod 4 rotates, and push away pendulum 5 simultaneously and also rotate, and direction is identical, pushes away pendulum 5 and backs down pressing plate 6; Less and the flexible rotation of pressing plate 6 weight, when pushing away pendulum 5 and backing down, can not increase too much burden to whole rotary course, and dropout push rod 4 rotates and whole device is threaded off, realizes the function of this device dropout;
Be subject under external shock situation, balance plate 7 overcomes spring 8 and does inertia motion, and clash into pressing plate 6, pressing plate 6 withstands and pushes away pendulum 5, to the push and block face 5-1 power F1 pushing away pendulum 5; Electromagnetic trip assembly 3 overcomes electromagnet spring 1, does inertia motion, clashes into dropout push rod 4, to dropout push rod 4 one power F2; Push away pendulum 5 synchronous with dropout push rod 4, around central rotation; When being hit, as shown in Figure 2, the power F2 that electromagnetic trip assembly 3 applies dropout push rod 4 and pressing plate 6 are to pushing away power F1 that pendulum 5 applies at the two ends of center of rotation, cause dropout push rod 4 to be failure to actuate or the amplitude of action less, whole device can not be caused to thread off, produce misoperation, there will not be the phenomenon of failure of apparatus.
