Abstract
The utility model provides a current measurement tool based on Hall sensors connected in parallel, which comprises a power supply, a resistor R, two connecting wires and at least two Hall sensors. The power anode end of each Hall sensor is connected with the positive output end of the power supply, and the power cathode end of the Hall sensor is connected with the negative output end of the power supply. The feedback output ends of all the Hall sensors are connected with a power common terminal GND through the resistor R. The two ends of the resistor R are connected with one end of each of the two connecting wires respectively. The other ends of the two connecting wires are combined to serve as a male head. According to the technical scheme of the current measurement tool provided by the utility model, at least two Hall sensors are connected in parallel, so that a plurality of cables can be simultaneously inserted into the Hall sensors connected in parallel. Therefore, the current measurement tool is suitable for being used for measuring single-phase large currents.
Description
Technical field
The utility model relates to electricity field, refers to especially a kind of Hall element translocation electric current frock.
Background technology
In a lot of application scenarios, all need electric current to detect, Hall element and electric current loop are all conventional sampling sensor.The DC component of the current signal that electric current loop is measured can be filtered in the time that current quality is analyzed, can not measure DC component, and the diameter of Hall element is less, in the time need to measuring the electric current of single-phase multi-cable line, single Hall element is because diameter limits, multi-cable line can not be inserted simultaneously, single-phase large electric current cannot be measured.
Utility model content
The purpose of this utility model is for the problems referred to above, and Hall element translocation electric current frock are provided, and can in Hall element in parallel, insert multi-cable line simultaneously, is applicable to measure single-phase large electric current.
For achieving the above object, the Hall element that the utility model provides translocation electric current frock, comprise power supply, resistance R, connecting line and at least two Hall elements, the power positive end of described Hall element all connects the forward output terminal of power supply, power-extremely all connects the negative sense output terminal of power supply, feedback output end all connects power supply public terminal GND through resistance R, and described resistance R two ends are connected with two connecting line one end respectively, and described two connecting line other ends synthesize male.
Above-mentioned Hall element translocation electric current frock, wherein, comprise two to six Hall elements.
Above-mentioned Hall element translocation electric current frock, wherein, comprise two Hall elements.
Above-mentioned Hall element translocation electric current frock, wherein, described power supply is Switching Power Supply.
Above-mentioned Hall element translocation electric current frock, wherein, described connecting line is barrel shape connecting line.
Compared with prior art, the Hall element that the utility model provides translocation electric current frock: be connected in parallel by least two Hall elements, thereby can insert multi-cable line simultaneously in Hall element in parallel, be applicable to measure single-phase large electric current.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
As shown in Figure 1, the Hall element that the utility model provides translocation electric current frock, comprise power supply 1, resistance R, connecting line 3 and at least two Hall elements 2, the power positive end of described Hall element 2 all connects the forward output terminal (+V) of power supply, power-extremely all connects the negative sense output terminal (V) of power supply 1, feedback output end all connects power supply public terminal GND through resistance R, is about to 2 parallel connections of at least two Hall elements.Described resistance R two ends are connected with one end of two connecting lines 3 respectively, and the other end of described two connecting lines 3 synthesizes the male that can be connected with instruments such as oscillographs, the signal that is resistance R two ends is exactly the measuring-signal of at least two Hall elements of parallel connection, thereby can at least two of a parallel connection Hall element 2, insert multi-cable line simultaneously, realize the measurement of single-phase large electric current.
In practical application, the number of Hall element 2 can be added as required, in general the number of Hall element 2 is two to six, be preferably two Hall elements 2, can realize like this measurement of single-phase large electric current, can avoid again number when Hall element 2 more time, the current signal phase mutual interference of the collection of each Hall element 2, affects measuring accuracy.Preferably, power supply 1 is Switching Power Supply, and connecting line 3 is barrel shape connecting line.
Compared with prior art, the utility model has the advantage of: by least two Hall elements 2 are connected in parallel, thereby can in Hall element in parallel 2, insert multi-cable line simultaneously, be applicable to measure single-phase large electric current.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
