specific Embodiment 1

[0037] Specific embodiment 1: please refer to Figure 1-4 A voltage stabilizer with intelligent protection function, including coil 1, protection part 2 and drive part 3.

[0038] The driving part 3 is located in the middle of the upper side of the coil 1 , the output end of the driving part 3 is connected with the protection part 2 , and the driving part 3 drives the protection part 2 to rotate around the axis of the coil 1 .

[0039] The protection part 2 includes a casing 21, a copper block 22, a moving plate 24 and a soft cover 25; the casing 21 is hollow inside, the moving plate 24 is located in the casing 21, and the lower end of the moving plate 24 is fixedly connected to the copper block 22 and the copper block 22. Through the casing 21, a carbon brush 23 is embedded in the lower end of the copper block 22 located on the lower side of the casing 21. The output end of the protection part 2 is the carbon brush 23. The carbon brush 23 is always pressed on the upper surfac...

specific Embodiment 2

[0045] Specific embodiment 2: different from specific embodiment 1, please refer to Figure 5 A voltage stabilizer with intelligent protection function, the upper wall of the differential airbag is made of elastic material, and the elastic coefficient of the upper wall of the differential airbag is greater than the elastic coefficient of the side wall of the differential airbag, that is, when the differential airbag enters the gas, the difference The side wall of the supplementary airbag is deformed before the upper wall of the poor supplementary airbag.

[0046] Under the condition that the upper wall of the differential airbag does not deform, the maximum volume of the differential airbag is smaller than the rated working volume of the air cavity. When the end face is in contact with the upper end face of the lower sleeve, the volume of the air cavity is reduced;

[0047] In this embodiment, the heights of the upper sleeve and the middle sleeve are both smaller than the hei...

specific Embodiment 3

[0050] Specific embodiment three: different from specific embodiment one or two, please refer to Image 6 A kind of voltage stabilizer with intelligent protection function, there is a gap between the side edge of the moving plate 24 and the inner wall of the housing 21, which reduces the sliding friction of the moving plate 24 and improves the flexibility of the carbon brush 23 to move down automatically.

[0051] The lower end of the side wall of the lower sleeve is provided with an air outlet, and the height distance between the air outlet and the upper end of the lower sleeve is greater than the height of the middle sleeve, so as to ensure that the air outlet is always open.

[0052] In the initial state of no air intake of the differential airbag, the lower end face of the differential airbag is lower than the inner wall of the upper side of the housing 21, and the outer periphery of the differential airbag lower than the inner wall of the upper side of the housing 21 is pr...

Abstract

The invention discloses a voltage stabilizer with an intelligent protection function, which belongs to the field of voltage stabilizers. A voltage stabilizer with an intelligent protection function, comprising a coil, a carbon brush and a driving part, characterized in that: the pressure of the carbon brush pressing the coil is constant, and the pressure is regulated by the protection part; the protection part includes a repulsion unit, which is connected with the carbon brush Connect directly or indirectly, and provide the carbon brush with pressure toward the coil direction; and a differential compensation unit, connected with the repulsion unit, and adjust the pressure provided by the repulsion unit; wherein, the pressure value provided by the repulsion unit is the same as the pressure value of the carbon brush toward the coil. The movement value has a linear positive correlation; it can realize that the pressing force of the carbon brush on the upper surface of the coil is always constant, effectively avoiding the problem of excessive wear or poor contact of the carbon brush.

Description

technical field [0001] The invention belongs to the field of voltage stabilizers, and more particularly relates to a voltage stabilizer with an intelligent protection function. Background technique [0002] The voltage stabilizer keeps the output voltage stable by adjusting the position of the carbon brush and changing the turns ratio of the coil. [0003] Usually the carbon brush material is relatively soft, long-term friction makes the carbon brush gradually wear out, until the carbon brush is completely worn out, the copper block inlaid with the fixed carbon brush will directly contact the surface of the wire package, resulting in a short circuit between turns, and eventually the wire package will be burned. Therefore, the carbon brushes must be replaced in time. [0004] The current solution is to check regularly, but because the power and voltage stability in different regions and at different times is different, the degree of wear of the carbon brushes will also be di...
