Abstract
The utility model discloses a detection device for judging watt hour meter and ammeter wiring, comprising a watt hour meter and/or an ammeter, wherein the front of the watt hour meter and/or the ammeter is serially connected with an incandescent bulb as a load. The detection device can effectively solve the technical problems that the detection on the accuracy of wiring and the quality of an element is complex, low in efficiency and not easy to realize when the watt hour meter and the ammeter are installed in a low-voltage apparatus cabinet. In addition, compared with the prior art, in the detection process, magnetic watt hour meter and ammeter are detected phase by phase through taking the incandescent bulb as the load to generate current added on a current terminal of a secondary circuit, and the accuracy of wiring and the quality of the element can be rapidly judged through the rotation direction of the indictors of the watt hour meter and the ammeter, thereby achieving maximum results with little effort.
Description
Technical field
The utility model belongs to a kind of device to electric elements and wiring check thereof, specifically, relates to a kind of pick-up unit that is used to judge watt-hour meter and reometer wiring.
Background technology
At present, in low-voltage electrical cabinet, often need to install watt-hour meter and reometer, want in the checkout procedure, the method that past adopts is that the electric current that utilizes current feedback circuit to produce is added on watt-hour meter, the reometer with the correctness of check wiring and the quality of components and parts itself, this mode is checked complexity, and efficient is low, and is difficult for realizing.
The utility model purpose
Technical problem to be solved in the utility model is, when in low-voltage electrical cabinet, watt-hour meter and reometer being installed, the check of the quality of the correctness of butted line and components and parts itself, it checks complicated, efficient is low, and be difficult for the technical matters of realization, and a kind of pick-up unit that is used to judge watt-hour meter and reometer wiring is provided.
Technical scheme provided by the utility model is, a kind of pick-up unit that is used to judge watt-hour meter and reometer wiring comprises watt-hour meter and/or reometer, and incandescent lamp bulb of series connection is as load before described watt-hour meter and/or reometer.
Described incandescent lamp bulb is 100-200 watt, and the voltage at described incandescent lamp bulb two ends is 220 volts.
Described incandescent lamp bulb produces the current terminal that electric current is added in secondary line as load.
Adopt technical scheme provided by the utility model, can effectively solve when in low-voltage electrical cabinet, watt-hour meter and reometer being installed, the check of the quality of the correctness of butted line and components and parts itself, it checks complicated, efficient is low, and the technical matters that is difficult for realization, simultaneously, compared with prior art, in checkout procedure, to the magnetic-type watt-hour meter, reometer directly produces the current terminal that electric current is added in secondary line by incandescent lamp bulb as load, by check mutually, pass through watt-hour meter, the rotation direction of ammeter pointer is judged the correctness of its wiring and the quality problems of components and parts fast, thereby reaches the effect of getting twice the result with half the effort.
Description of drawings
Fig. 1 is the utility model circuit connection diagram;
Wherein, 1 is bulb, and 2 is reometer.
Embodiment
Technical scheme provided by the utility model is, a kind of pick-up unit that is used to judge watt-hour meter and reometer wiring comprises watt-hour meter and/or reometer 2, and incandescent lamp bulb 1 of series connection is as load before described watt-hour meter and/or reometer 2; Described incandescent lamp bulb 1 is 100-200 watt (comprising 100 watts and 200 watts), and the voltage at described incandescent lamp bulb 1 two ends is 220 volts; Described incandescent lamp bulb 1 produces the current terminal that electric current is added in secondary line as load.
To be solved in the utility model is to adopt to utilize incandescent lamp bulb 1 to produce the current terminal that electric current is added in secondary line as load, reaches quick judgement watt-hour meter, reometer 2 wiring correct method, as shown in Figure 1 (is example mutually with A).The difference of itself and other test is to use quick and convenient, realizes easily.
The concrete implementation of the utility model (Fig. 1) following (with A is example mutually, and B, C phase study method are identical):
1, at first check watt-hour meter wiring on request, promptly the A phase voltage is got in the watt-hour meter voltage loop, and current return is got the electric current of A phase current mutual inductor.
2, incandescent lamp bulb 1 is sealed in watt-hour meter A phase current loop behind the voltage of getting the A phase on the voltage terminal, correctly then incandescent lamp bulb 1 is normally luminous as wiring, and watt-hour meter just changes; Otherwise can judge to have wiring error, treat that further butted line checks.
Claims (3)
1, a kind of pick-up unit that is used to judge watt-hour meter and reometer wiring comprises watt-hour meter and/or reometer (2), it is characterized in that, at described watt-hour meter and/or reometer (a 2) incandescent lamp bulb of preceding series connection (1) as load.
2, a kind of pick-up unit that is used to judge watt-hour meter and reometer wiring according to claim 1 is characterized in that described incandescent lamp bulb (1) is 100-200 watt, and the voltage at described incandescent lamp bulb (1) two ends is 220 volts.
3, a kind of pick-up unit that is used to judge watt-hour meter and reometer wiring according to claim 2 is characterized in that, described incandescent lamp bulb (1) produces the current terminal that electric current is added in secondary line as load.
