But, when gauging table meter process mutual inductor (current transformer, voltage transformer (VT)) incoming transport electrical network, can't utilize multimeter inspection.
The utility model content
The utility model aims to provide a kind of gauging table meter testing device, to solve the problem that can't carry out wiring check in the prior art behind the gauging table process mutual inductor incoming transport electrical network.
To achieve these goals, the utility model provides a kind of gauging table meter testing device, comprising: power supply, and its first end is connected with first test pencil; And loudspeaker, its first end links to each other with second end of power supply, and second end of loudspeaker is connected with second test pencil.
Further, power supply and loudspeaker are for being fixedly connected.
Further, first end of power supply is anodal, and second end of power supply is a negative pole.
Further, power supply is connected through flexible circuit conductor with first test pencil.
Further, loudspeaker is connected through flexible circuit conductor with second test pencil.
Further, power supply comprises battery case and is positioned at the interconnective a plurality of batteries of battery case.
Further, battery is four joints, and battery is 1.5V, and loudspeaker is the loudspeaker of 6V.
Use the technical scheme of the utility model; Through first test pencil and second test pencil different voltages with different, current coil are measured; Loudspeaker produces high pitch and bass in the measuring process; Whether the wiring of judging the gauging table meter in view of the above is correct, like this, effectively solves the problem that can't carry out wiring check in the prior art behind the gauging table meter process mutual inductor incoming transport electrical network.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the structural representation according to the embodiment of the gauging table meter testing device of the utility model.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
As shown in Figure 1, as can be seen from the figure, the gauging table meter testing device of present embodiment comprises: power supply 10, loudspeaker 30, first test pencil 51 and second test pencil 53.Wherein, the positive pole of power supply 10 is connected with first test pencil 51, and the negative pole of power supply 10 is connected with first end of loudspeaker 30, and second end of loudspeaker 30 is connected with second test pencil 53.Measure through first test pencil 51 and second test pencil 53 pairs of different voltages with different, current coils; Loudspeaker 30 produces high pitch and bass in the measuring process; Whether the wiring of judging the gauging table meter in view of the above is correct, effectively solves the problem that can't carry out wiring check in the prior art behind the gauging table meter process mutual inductor incoming transport electrical network.
Specifically, for three-phase circuit, one being example mutually wherein; Suppose that this is the A phase; During current return detected, the positive pole of reometer meter did not pass through mutual inductor coil, utilized first test pencil 51 of the gauging table meter testing device of present embodiment to connect the positive pole of A phase current lines; Second test pencil 53 connects the positive pole of mutual inductor A phase, representes that then wiring is correct if send high pitch; The negative pole of reometer meter is through mutual inductor coil, utilizes first test pencil 51 of the gauging table meter testing device of present embodiment to connect the negative pole of A phase current lines, and second test pencil 53 connects the negative pole of mutual inductor A phases, representes that then wiring is correct if send bass.
During voltage circuit detects, mainly be whether the wiring that the A phase voltage end of meter scale meter is connected with AC power has cut-off point.Utilize first test pencil 51 of the gauging table meter testing device of present embodiment to be connected to wiring place near gauging table meter A phase voltage end, wiring place that second test pencil 53 is connected near AC power, if loudspeaker are sounded, it is that wiring is correct that the expression wiring does not have cut-off point.
In the said process, loudspeaker send high pitch and represent the secondary circuit wiring not pass through coil, and resistance is little to be high pitch; Bass represents the secondary circuit wiring through coil, and resistance is bass greatly.
In the above-described embodiments, preferably, power supply 10 and loudspeaker 30 are for being fixedly connected.Make gauging table meter testing device Stability Analysis of Structures, easy to use.
Preferably, power supply 10 is connected through flexible circuit conductor with first test pencil 51, and loudspeaker 30 is connected through flexible circuit conductor with second test pencil 53.It is convenient to use flexible circuit conductor to connect use.
Preferably, power supply 10 comprises battery case and is positioned at the interconnective a plurality of batteries of battery case.As shown in Figure 1, preferably, battery is four joints, and battery is 1.5V, and loudspeaker 30 is the loudspeaker of 6V.Structure is less, has good portability.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
