Description
Technical field
The utility model relates to a kind of current measuring equipment that is used for, and is specifically related to a kind of pointer alternating current ammeter.
Background technology
The mount type pointer-type alternating current ammeter such as the 6L2 type that in the electric power low-pressure system, use at present, 42L6 type etc., carry out CNS GB/T7676-98, this type of reometer comprises housing, surface plate, pointer and drives the current detecting mechanism of hand motion, described current detecting mechanism is electrically connected with binding post on the housing, and the surface plate subscript is shown with nonlinear scale mark and corresponding indicating value.Its weak point is that the amount limit of reometer is fixed, unadjustable, thereby for needing to change the user of reometer amount limit because of the change of tested value or because of adjusting range ability, can only be to select to change the reometer of appropriate amount limit more to satisfy requirement in the measurement, this have brought inconvenience to the user.
In fact, the normal indirect measurement of using current value is promptly adopted and the corresponding current transformer of reometer in the power measurement, the rated current of mutual inductor secondary side is consistent with the rated current of reometer, thereby, after the no-load voltage ratio that changes current transformer, can in fact change the amount limit of reometer; For example, carry out the LM type polytropic ratio current transformer of CNS GB1208-1997, in ac current measurement, be widely used because of easy to use, the rated current of the secondary side of this mutual inductor and the rated current of reometer are 5 amperes, are used the reometer that can constitute different ranges and realize ac current measurement.Yet reometer in the market is monotropic ratio, and the indicating value that indicates on its display board is determined, thereby when passing through to change the no-load voltage ratio change range of mutual inductor when using, the indicating value numeral on the reometer can not be suitable for, for avoiding error in reading, must change reometer.This both can make troubles to the user, also can cause waste.
Summary of the invention
The utility model purpose provides a kind of reometer that can regulate measuring amount limit marker value, when being used with the polytropic ratio current transformer to be fit to it, needs to regulate the requirement that the reometer amount is limit.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pointer reometer, the current detecting mechanism that comprises housing, surface plate, pointer and driving hand motion, described current detecting mechanism is electrically connected with binding post on being fixed on housing, the surface plate subscript is shown with nonlinear scale mark, the rectilinear motion adjusting mechanism that also includes display board and cooperate with it, the position that indicates indicating value on the described surface plate has window, the corresponding indicating value that is provided with different amount limits on the described display board, adjacent every group of indicating value equidistantly arranged along the display board moving direction.
In the technique scheme, described current detecting mechanism is a prior art, design of the present utility model is, the original local windowing that shows indicating value on surface plate, add a display board that can move at the rear of surface plate, be printed on many group numerals on the display board, indicating value corresponding to difference amount limit, because the position of each indicating value is not equally distributed, after consideration, each group indicating value numeral rectilinear direction is equidistantly arranged, thereby, by the rectilinear motion adjusting mechanism, corresponding indicating value is exposed from the surface plate window, become the indicating value of current amount limit.The change amount needs only the position of adjusting display board in limited time.In order to guarantee the rectilinear motion of display board, avoid being offset the display error that causes, can seat board be set at the rear of display board, but display board vertical direction or horizontal direction move relative to seat board, the both sides of display board adopt oat tail groove structure to be assemblied on the seat board.Certainly, the rectilinear motion adjustment of display board is a kind of prior art, and those skilled in the art can provide other fully and adjust structure.
In the technique scheme, described rectilinear motion adjusting mechanism is, is fixed with tooth bar on the display board, is provided with and described tooth bar meshed gears, and the outer knob of transmission shaft one end of gear and housing is fixedlyed connected.
Wherein, the spiral arm of described knob is provided with screw, and corresponding each amount limit marker indicating value display position is provided with the boss nut on the described housing, and described screw cooperates the location with the boss nut.
Perhaps, described rectilinear motion adjusting mechanism is a driving lever, and driving lever one end is fixedlyed connected with display board, and display board is spacing by chute, is provided with a plurality of elastic positioning structures in the chute, and each elastic positioning structure matches with each amount limit marker indicating value display position.
Further technical scheme, described rectilinear motion adjusting mechanism is the lengthwise movement adjusting mechanism.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. because the utility model is to reometer surface plate windowing and adds display board, realize that the demonstration of different amount limits is changed, thereby can directly apply on the existing reometer that can not change the element board and the gauge outfit of primary current table, it is convenient to realize;
2. the utility model can realize that same reometer shows that to the measurement of difference amount threshold currents the user is easy to use, and changing at electric current is more greatly to change table, and a kind of reometer can be fit to multiple current transformer simultaneously, uses convenient;
3. gear of the present utility model-tooth bar engaging structure, the rotation gear shift of knob is very easy, and can locate by screw, guarantees that the demonstration amount of window on indicatrix limit that knob locatees and the surface plate is limit consistent.
