According to the technical scheme, the praseodymium neodymium dysprosium damper for an electric meter is excellent in magnetic property, high in coercive force, simple in structure and convenient in use.
Description
Technical field
The utility model relates to a kind of kilowatt-hour meter permanent-magnet material damper that is used for the electric energy metrical field, and what be specifically related to is a kind of kilowatt-hour meter praseodymium neodymium dysprosium damper.
Background technology
Existing watt-hour meter damper all is that what to adopt is aluminium nickel class permanent magnetic material mostly, and these material price general chargeds are expensive, and the permanent magnet volume of support is big; Handy more noble metal, cost certainly will increase, the damper of these made; Coercive force is lower, and magnetic property is stable inadequately.Because the physics and the machining characteristic of above-mentioned material, the damper of manufacturing often comparative structure are complicated, assembling difficulty, principle of work are to realize adjusting damping torque through the magnetic flux that changes the gap, so setting range is restricted.
The utility model content
The utility model is according to above-mentioned deficiency, provides that a kind of magnetic property is good, coercivity is high, to regulate the kilowatt-hour meter praseodymium neodymium dysprosium damper of damping action point.
For realizing above-mentioned purpose; The technical scheme of the utility model is a kind of kilowatt-hour meter praseodymium neodymium dysprosium damper; Be made up of rare-earth permanent magnet, magnetic temperature controller and sliding support, on the described magnetic temperature controller temperature-adjusting device be housed, temperature-adjusting device is made up of thermoelectric heating device and refrigerator.
Describedly constitute damping body, be mounted with inductive probe on it, be mounted with hummer on the adjustment screw by the magnetic temperature controller.
Described rare earth permanent magnet body and function Pr-nd-dy alloy material.
The beneficial effect of technique scheme is:
1) adopts the application point that changes damping force, realize adjusting the mode of damping torque, abandoned the mode of the magnetic flux in the adjustment yoke distance fully.Magnetic flux is stable, and dependable performance is adjusted meticulous.
2) adopt the Pr-nd-dy alloy material, coercivity is high, and magnetic property is stable.
3) on the magnetic temperature controller temperature control equipment is housed, temperature control equipment is made up of thermoelectric heating device and refrigerator, guarantees the stable, easy to adjust of magnetic flux.
4) be mounted with inductive probe on the damping body, be mounted with hummer on the adjustment screw.Remind the user to note the rhythm of regulating, make the location of damping body reach the best located point.
Description of drawings
Fig. 1 is the utility model one-piece construction synoptic diagram.
Fig. 2 is the utility model cross-sectional view.
Embodiment
Do bright specifically below in conjunction with accompanying drawing and embodiment to the utility model.
By illustrated in figures 1 and 2, a kind of kilowatt-hour meter praseodymium of the utility model neodymium dysprosium damper, operation principle is to adopt the application point that changes damping force, realizes adjusting the mode of damping torque, has abandoned the mode of the magnetic flux in the adjustment yoke distance fully.Constructed by the magnetic plate 2 sliding support 9, dysprosium praseodymium neodymium permanent magnets 3 and 11, the magnetic temperature controller 4 and 10, T-shaped iron 5, spring 6,? Slide bracket and screws 8 and 9 rails 7 and other parts composed of magnetic plate 2 is fixed to the bracket 12, and praseodymium neodymium permanent magnets 3 and 11 dysprosium, magnetic temperature controller 4 and 10 are symmetrically placed in the holder 12 on the guide rail 7, the sliding support 9 can be moved, Pr Nd Dy the permanent magnet 3 and the magnetic plate 2 magnetic gap formed between the slide holder 9, T-shaped iron 5, dysprosium praseodymium neodymium permanent magnet 3, the magnetic temperature controller 4 and the sheet 6 is composed of a spring damping body 14, with the adjusting screw 8 can adjusting the damping body 14 the position of the rail 7, the damping body 14 are arranged on the sensor probe 13, the adjusting screw 8 is arranged with a buzzer 15, when the adjusting screw 8 adjusted so that the damping member 14 does not reach the optimal positioning, the sensor probe signal 13, the buzzer 15 has been working, when the damping body 14 reaches the optimal positioning, the buzzer 15 stops, positioning the end, so as to adjust the effect, the spring plate 6 can ensure that the process of adjustment of the damping body 14 stability.T sections 5 can magnetic conduction, forms magnetic loops with praseodymium neodymium dysprosium permanent magnet 3, magnetic conductive board 2; Magnetic temperature controller 4 is provided with temperature-adjusting device 1 is housed, and temperature-adjusting device 1 is made up of thermoelectric heating device and refrigerator, the temperature in balance magnetic field, if temperature is too high, and refrigerator work; If temperature is low excessively, the work of some heating element.Can guarantee that magnetic field does not change with variation of temperature, realize stablizing the effect of magnetic flux.
