Abstract
The utility model relates to a magnetic ring assembly of a watt-hour meter magnetic bearing with a compensation ring. A magnetic ring 2 is arranged in a magnetic ring lining 3, and a compensation ringThe utility model relates to a magnetic ring component of an electric meter magnetic bearing with a compensation ring. A magnetic ring 2 is arranged in a magnetic ring bushing 3 and a compensation rin is arranged on the outside diameter of the magnetic ring. The assembly is arranged on the kilowatt-hour meter with a ferrite bearing. The utility model has the advantages that the height of the dial g is arranged on the outer diameter of the magnetic ring. After the component is arranged on a ferrite bearing electric meter, the utility model has the advantages that the temperature of the electricplate of the kilowatt-hour meter is in the range of temperature variation of 50D DEG C-40 DEG C and can not be varied following with the variation of the temperature. The kilowatt-hour meter with a fe meter dial ranges from 50 DEG C to minus 40 DEG C and is not changed as a change of an external temperature. Therefore, in the temperature range, aluminum-nickel-cobalt bearing electric meter can be rrite bearing can replace a kilowatt-hour meter with an aluminum nickel cobalt bearing in the temperature area. replaced by the ferrite bearing electric meter.
Description
Technical field
The utility model relates to watt-hour meter magnetic bearing.Specifically, for being with the magnetic bearing magnetic ring component of compensated loop.
Background technology
The magnetic bearing watt-hour meter requires the height of dial plate not change with the change of temperature, because ferritic temperature coefficient is too big, temperature is bigger to the influence of dial plate height, thus need compensation, though China's patent 96103029.1 and 96205926.9 pairs of temperature once had compensation, but it is to be contained on the pole-face of magnet ring, be the series connection of magnetic circuit, can only be applicable to-10 degrees centigrade～+ 50 degrees centigrade area, if temperature is more than or equal to-10 degrees centigrade, dial plate just contacts with the damping magnet steel, causes that dial plate does not change.Because the serviceability temperature scope of China's ammeter is 50 degrees centigrade～-40 degrees centigrade, above-mentioned patent can not adapt to market demand.
Summary of the invention
The purpose of this utility model is a kind of magnetic bearing watt-hour meter that can normally use in 50 degrees centigrade～-40 degree celsius temperature scopes of design.
The watt-hour meter magnetic bearing magnetic ring component of the utility model band compensated loop comprises magnet ring lining, magnet ring, is contained in the compensated loop on the magnet ring external diameter.
The material of compensated loop can be the magnetic temp compensating magnetically soft alloy material, such as 1J
38With iron nickel complexing gold copper-base alloy, compensated loop should be the garden annular.
Make product, through test, it can both make dial plate in 50 degrees centigrade ,-25 degrees centigrade ,-40 degrees centigrade temperature range height not Yin Wendu change and change.Therefore, the ferrite bearing watt-hour meter with this utility model assembling can extensively replace aluminium nickel cobalt bearing watt-hour meter.Thereby it has following superiority.
1, ferritic price is low more than aluminium nickel cobalt, can reduce cost.
2, ferritic coercive force is the several times of aluminium nickel cobalt, can prolong the life-span of ammeter.
3, ferritic recovery is better than aluminium nickel cobalt, and promptly annual the need through the high temperature of associating to normal temperature returns the temperature cycles of normal temperature to low temperature, and the error of ammeter will change in this temperature cycles, but ferritic variation is littler.
4, the ferrite bearing can improve the stability of watt-hour meter.
Description of drawings
Accompanying drawing is the structural drawing of the magnetic ring component of the watt-hour meter magnetic bearing of band compensated loop.
Embodiment
With reference to the accompanying drawings, magnet ring 2 is contained in the magnet ring lining 3, and compensated loop 1 is contained on the external diameter of magnet ring 2, and links to each other with magnet ring lining 3.
Claims (2)
1, a kind of magnetic ring component of the watt-hour meter magnetic bearing with compensated loop comprises magnet ring (2), it is characterized in that magnet ring (2) is contained in the magnet ring lining (3) in addition, and compensated loop (1) is contained on the external diameter of magnet ring (2), and links to each other with magnet ring lining (3).
2, according to the magnetic ring component of the bearing of the watt-hour meter magnetic bearing of the described band compensated loop of claim (1), the material that it is characterized in that compensated loop (1) is the garden ring of magnetic temp compensating magnetically soft alloy material.
