Description
Technical field
The utility model relates to testing device for energy meter technical field, relates in particular to a kind of Simple electric-energy table proving installation that is easy to carry and uses.
Background technology
Electric energy meter, is for measuring the instrument of electric energy, claiming again watt-hour meter, energy meter, and kilowatt-hour table, refers to measure the instrument of various electrical quantities.When electric energy meter access circuit-under-test, in current coil and potential winding, just there is exchange current to flow through, these two exchange current produce respectively the magnetic flux of alternation in their iron core; Alternating flux, through aluminium dish, induces eddy current in aluminium dish; Eddy current You is subject to the effect of power in magnetic field, thereby makes aluminium dish obtain torque and rotate.The power of load consumption is larger, larger by the electric current of current coil, and the eddy current inducing in aluminium dish is also larger, and the moment that aluminium dish is rotated is just larger.The size that is torque follows the power of load consumption to be directly proportional.
Power is larger, and torque is also larger, and aluminium dish rotates also just faster.When aluminium dish rotates, be subject to again the effect of the braking moment of permanent magnet generation, braking moment and active moment opposite direction; The size of braking moment is directly proportional to the rotating speed of aluminium dish, and aluminium dish rotates sooner, and braking moment is also larger.When active moment and braking moment reach transient equilibrium, aluminium dish is by uniform rotation.The electric energy that load consumes is directly proportional to the revolution of aluminium dish.When aluminium dish rotates, drive counter, consumed electric energy is indicated.The simple procedure of electric energy meter work that Here it is.
Electric energy meter need to be done while running word test, pull down electric energy meter from user there, takes in measuring room and does.At present the electric energy meter test board volume in measuring room is large, heavier, can not take on-the-spot use, pulls down test electric energy testing process and expends time in longlyer, affects the normal electricity consumption of user.In addition, be transported in the process in measuring room after pulling down electric energy meter, inevitable because vibration in transit causes electric energy meter inaccurate, cause to test to lose meaning.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of portable electric meter and runs word proving installation, while using described device to run word test to user's electric energy meter, has easy to usely, does not affect user power utilization and work efficiency high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of portable electric meter runs word proving installation, it is characterized in that comprising fixed head, wire, the first connection terminal, the second connection terminal and electric energy meter, described electric energy meter is fixed on described fixed head, power supply is connected with the input end of electric energy meter through wire, the output terminal of described electric energy meter is connected with two the first connection terminals through wire, and two the second connection terminals connect load through wire.
Further, between described power supply and electric energy meter, be provided with power switch.
Further, described electric energy meter is prepayment meter.
The beneficial effect that adopts technique scheme to produce is: described device can on-the-spotly run word test to user's electric energy meter, easy to use, does not affect user power utilization, saves man-hour, reduces line management person's labour intensity, has improved work efficiency; Be conducive to investigate and prosecute at the scene and obtain the inner stealing evidence of electric energy meter, user is made to punishment, remedy the electricity charge, reduce line loss; Volume is little, and the use that is easy to carry, has further reduced tester's labour intensity; By running word, test, can grasp which electric energy meter should verification, and which electric energy meter does not need verification can continue to use, and avoids blindly verification electric energy meter, wastes time and energy; By scene, run word and test, can check and supervise the accuracy of metering calibration person verification electric energy meter and have or not corrupt practice, increase the transparency of verification electric energy meter; Word test is run at scene, avoids causing the inaccurate problem of electric energy meter because of vibration in transit, make to run word test more accurate.In addition, described device simple in structure, low cost of manufacture, has good popularization and prospect of the application.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, power supply 2, electric energy meter 3, wire 4, the first connection terminal 5, the second connection terminal 6, load 7, power switch.
