Abstract
The utility model relates to an easily mounting and regulating watt-hour meter calibrating device, comprising a frame and a calibrator, a meter hanging frame, a photometer head and the regulating frame of the photometer head which are installed in the frame. The calibrator is composed of a plurality of functional modules, wiring terminals are all arranged on the functional modules, and the interconnection of the wiring terminal of each functional module can be realized according to requirements. A module box is arranged in the frame, and each functional module is inserted and installed in the module box. The utility model has the advantages of convenient installation, convenient regulation and convenient maintenance.
Description
The utility model belongs to pick-up unit, relates in particular to the pick-up unit to electric energy meter.
Electric energy meter checking device generally adopts work desk-top, and a meter hanging frame promptly is set on a big worktable, and the verification object is suspended on the meter hanging frame, and photometer head to the pre-check object, is carried out verification by the checker that is contained in below the worktable to it.The layout of the checker in the desk-top calibration equipment of this work is in a mess and this device heaviness, and volume is very big, moves inconvenience, can not satisfy the requirement of the calibration of going out at all, calibrated meter can only be taken the fixed location verification.Rural area and backcountry needs of calibration of going out for convenience, so some adopts box calibration equipment, it is that checker is contained in the casing, overcome the defective of the desk-top calibration equipment of working to a great extent, but still having circuit arrangement and the mixed and disorderly deficiency of line in the case, these calibration equipments all are not easy to produce and maintenance.
The purpose of this utility model provides a kind of installation, debugging and electric energy meter checking device easy to maintenance.
For achieving the above object, the utility model adopts following technical scheme: this electric energy meter checking device of being convenient to debug installation, comprise framework and be contained in framework interior checker, meter hanging frame, photometer head and adjusting bracket thereof, checker is made up of plurality of function modules, be equipped with connection terminal on the functional module, the connection terminal of each functional module is according to requiring to interconnect.
Be provided with module cage in the framework, each functional module is inserted in the module cage.
Locating slot is all arranged before and after each functional module lower end, and there is the reference column corresponding with locating slot the inwall lower end before and after the module cage, and locating slot is held on the reference column.
Each functional module surface is equipped with heat radiator.
Each functional module front and back end by screw retention on module cage.
The plurality of function modules that the utility model is made function opposite independent with checker is contained in the case, each functional module is only connected by limited connection terminal, changed the present situation that circuit configuration is mixed and disorderly, line is complicated in the existing product case, make production run standardization more, debug easier for installation.Because functional module can plug easily, also make maintenance become simple.In addition, adopt modular design can also produce whole device miniaturization and portability more, lift convenient calibration equipment.
Further specify the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the module cage rear view that functional module is housed;
Fig. 3 is that figure cuts open in the module cage forward sight office that functional module is housed.
Embodiment: in this is convenient to debug the framework 1 of electric energy meter checking device of installation, checker is housed, checker is made up of several Elementary Function modules 9, module is installed in the module cage 7, is fixed on the module cage by screw 9 ' a before and after each Elementary Function module, and module cage 7 is packed in the framework 1.On each functional module, be equipped with connection terminal 12, connect according to designing requirement between the connection terminal of disparate modules.Be equipped with heat radiator 8 above the Elementary Function module 9 at each, in the present embodiment on the module 9 the heat radiator of adorning 8 be the peak shape.All there is locating slot 9 ' front and back of each Elementary Function module lower end, have in the lower end of module cage 7 front and back and locating slot 9 ' the corresponding reference column 10, and locating slot 9 ' is stuck on the corresponding reference column 10 when packing into.Casing back shroud 7 ' is pull-type for inserting, and back shroud and connection terminal correspondence position have open slot 7 ' a.
Screw is laid down, and functional module can easily be extracted from the top of module cage, keeps in repair very convenient.
The form that this checker is made up of functional module can be used for using now desk-top, box or improve after portable.
