Description
Technical field
The present invention relates to a kind of intelligent electric energy meter and examine and determine/have good luck integrated device.
Background technology
Along with the development of electric power and metering, electric-power metering and relevant departments are more and more higher to the demand and the cry of the electric energy meter calibrating apparatus of the electric energy meter calibration/function integration of having good luck, and its purpose mainly is to be convenient to equipment control, is convenient to data sharing.Electric energy meter calibration/the integrated device of having good luck is of electric energy meter calibrating apparatus, and it combines the have good luck all functions of device of electric energy meter calibrating apparatus and electric energy meter, is for electricity consumption measurement centre and the metrological supervision check the most general a kind of equipment that uses.And the electric energy meter calibration of routine in the prior art/have good luck integrated device as shown in Figure 1, be a kind of accurate integrative machine, on first dial framework, be fixed with a pair of first electrician source binding post 11A ', a pair of first electric energy meter circuit connection post 13A ', a pair of first electron source binding post 12A '.On second dial framework, be fixed with a pair of second electrician source binding post 11B ', a pair of second electric energy meter circuit connection post 13B ', a pair of second electron source binding post 12B '.Electrician source C1 ' and electron source C2 ' are installed on the clothes closet.One of the first electrician source binding post 11A ' is connected with electrician source C1 ', and one of another root and the second electrician source binding post 11B ' is connected, and another root of the second electrician source binding post 11B ' is connected with electrician source C1 '.One of the first electron source binding post 12A ' is connected with electron source C2 ', and one of another root and the second electron source binding post 12B ' is connected, and another root of the second electron source binding post 12B ' is connected with electron source C2 '.Be connected with the interior ammeter loop of first dial framework between the two first electric energy meter circuit connection post 13A '.Be connected with the interior ammeter loop of second dial framework between the two second electric energy meter circuit connection post 13B '.
Electrician source C1 ' mainly is made up of stepup transformer, current lifting device, pressure regulator, and the utility appliance of electrician source C1 ' is made up of stepper motor, measurement mutual inductor and a little electrons components and parts and electrical fuse.Electrician source C1 ' is used for output voltage, electric current.
Electron source C2 ' is by program-controlled derived digital signal, power amplifier and boost, current lifting device forms, and the utility appliance of electron source C2 ' comprises standard scale, central authorities' control power supply, keyboard, error checking instrument, Communications Interface Unit, relay array, measuring equipment or the like.Electron source C2 ' is used for output voltage, electric current, also may command frequency modulation rate, phase modulation position, output harmonic wave.
The output of electrician source C1 ' and electron source C2 ' electric weight is all according to the accuracy requirement and the stability requirement of national regulation.
The two stage mechanisms of prior art 48 epi-positions, must do certificate test simultaneously or have good luck test, and can not realize that a dial framework is done certificate test, another dial framework is done this function of test of having good luck, that is to say the all-in-one that is not standard, if the user purchases a calibrating installation and though the device of having good luck can be finished above two functions calibrating,, this obvious cost of equipment gets obviously to be increased, the hold facility area also obviously increase, thereby inadvisable.So have only and realize two dial frameworks when electric energy meter calibrating apparatus and examine and determine/have good luck test simultaneously respectively, and can two functions switch smoothly, save a large amount of loading, unloading table times, can greatly increase work efficiency, but realize that such function must have two cover power sources, from saving cost, an optional cover electronic power source, for inspection purpose, the precision index requirement is arranged; One cover electrician source, the usefulness of having good luck, index request is low.Such cost uses producer to bear.It is as follows that each big manufacturer adopts conventional solution two function switching methods at present: use universal switch or relay, require to reach 100A in view of the device output current is general.If adopt the universal switch method, generally need 4 pairs of contacts and connect, use as one pair of contact; And adopt the relay method, and be to consider device output stability and long term reliability, generally adopt single-contact magnetic latching relay, two and connect use.In principle, can reach the Design of device requirement.But still deposit the weak point of following several respects:
1, it is too many that current return increases the contact, just increased contact resistance simultaneously, to high-precision electric energy meter calibrating apparatus, will have a strong impact on precision and stability, also has carrying load ability.
2, additionally increased a large amount of connecting lines, and these connecting lines must be more than 20 squares, allow big electric current line, increase material cost, increase time cost, also increase technologic manufacture difficulty, influence attractive in appearance by 100A.
3, use the universal switch method, each switch needs the contact chip number:
6 (paying the contact) * 4 (contact also connects)=24,
Its length is considerable, and switching universal switch is not that common people can pull, and the operating personnel of equipment are generally in the majority with the women, its result can to and know, so very impracticable.
4, use the relay method, magnetic latching relay costs an arm and a leg, and also needs control module and working power, and cost is a big problem, and wiring is more.In use also there is integrity problem or the like, inadvisable.
