Description
Technical field
It is the utility model is related to measure training technique field, more particularly to a kind of for electric energy metering device accident analysis
Phasor combined appliance for teaching.
Background technology
With the continuous popularization and application of novel intelligent electric energy meter, the generation of all kinds of metering exceptions in scene so that metering working
Personnel must grasp the ability of field failure analysis.When generation metering device wiring error, i.e. man-made fault or equipment fault
When, it needs through theoretical means, in conjunction with field failure phenomenon, using the method for misconnection line analysis, is used during correct metering fault
Family uses the electricity electricity charge, and completion failure electricity, which chases after, moves back benefit.The phasor knowledge used in the analysis process is hard to understand, is unfavorable for learning
The understanding and grasp of member.
Utility model content
The purpose of this utility model is to provide a kind of phasor combined appliance for teaching for electric energy metering device accident analysis.
For this purpose, technical solutions of the utility model are as follows：
A kind of phasor combined appliance for teaching for electric energy metering device accident analysis, including dial, three phase voltage phasors
Item, three phase current phasor items and two line voltage phasor items；Dial is the round dish that surface is equipped with 12 evenly divided lines；
Three phase voltage phasor length are identical and are fixed on dial in the form of star-like distribution；Three phase current phasor items and two
One end of a line voltage phasor item is pivotally fixed on the center of dial, and the length of two line voltage vector items
Degree is adjustable.
Further, two line voltage vector items are draw and insert-type structure.
Further, further include the magnetic absorption part being arranged at the dial back side.
Further, described three phase voltage phasor strip adoptions, the three kinds of different colors distinguish, and three mutually electric
It is identical that stream phasor item distinguishes corresponding phase voltage phasor color.
Compared with prior art, which is conducive to improve teaching
Training quality can efficiently complete structure and the recovery of phasor diagram, promote student and grasp effect；The teaching aid is easy to operate, portable
Feature has very high plasticity, is easy to replicate and promote；Alternative original manual setting-out is not straight, is difficult to clearly observe and divide
The inconvenience of analysis；In addition to this, which has absorption fixed function, facilitates carry out teaching demonstration, keeps the content of courses more intuitive.
Description of the drawings
Fig. 1 is the structural representation of the phasor combined appliance for teaching provided by the utility model for electric energy metering device accident analysis
Figure.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment is described further the utility model, but following embodiments are right absolutely not
The utility model has any restrictions.
As shown in Figure 1, this is used for the phasor combined appliance for teaching of electric energy metering device accident analysis, including dial, three phases
Voltage phasor item, three phase current phasor items and two line voltage phasor items；Dial is that surface is equipped with 12 evenly divided lines
Round dish；The magnetic absorption part at the dial back side, it is convenient that teaching aid is fixed；Three phase voltage phasor length it is identical and
It is fixed on dial in the form of star-like distribution；One end of three phase current phasor items and two line voltage phasor items is with can
The mode of rotation is fixed on the center of dial, and the adjustable in length of two line voltage vector items, and line voltage vector item passes through
The mode of folding carries out length adjustment；Preferably, two line voltage vector items are draw and insert-type structure, and line voltage vector item passes through pumping
Slotting mode carries out length adjustment；Described three phase voltage phasor strip adoptions, the three kinds of different colors distinguish, and three
It is identical that phase current phasor item distinguishes corresponding phase voltage phasor color.
The application method of phasor combined appliance for teaching provided by the utility model for electric energy metering device accident analysis is as follows：
When being analyzed metering device using phasor diagram, first, which is passed through into the dial back side
Magnetic absorption part the teaching aid is fixed；Then, according to different metering faults, phase voltage phasor item, phase current are utilized
Phasor item and line voltage phasor item form different phasor diagrams, and during forming phasor diagram, three phase voltage phasor items begin
It remains stationary eventually, three phase current phasor items and line voltage phasor item can be around the center rotatings of dial, with this
Meanwhile two line voltage phasor items can carry out length transformation in a manner of pulling and pushing or in the way of folding.
