Abstract
The utility model discloses a novel on-site calibration instrument voltage crimping device. Two corresponding groups of screw holes and fixing screws are located at the left and right sides of a shell respectively, each of the fixing screws is inserted in the corresponding screw hole, four corresponding groups of voltage connecting holes and voltage contacts are arranged, the front end of each phase of the voltage contact is fixed in the corresponding voltage connecting hole, the front and rear parts of each phase of the voltage contact are cylindrical conductors which are fixed by a spring at the middle part, and each phase of the voltage contact is sleeved by a corresponding sheath. The novel on-site calibration instrument voltage crimping device can completely avoids a problem that a voltage clamp falls off in the on-site calibration process of an electric energy meter, and has the characteristics of good reliability and high measurement precision.
Description
Technical field
The utility model relates to a kind of on-site calibrator voltage compression bonding apparatus.
Background technology
In Watt-hour meter's field test work, the current return of on-site calibrator need to be connected in series in the current return of tested table meter and gather current signal; The voltage circuit of tester is parallel on the voltage circuit of tested table meter and obtains voltage signal.Conventionally; the mode of utilizing crocodile clip to be fixed to terminal box voltage screw contact realizes the parallel connection of voltage circuit; but crocodile clip is subject to the impact of gravity and jaws snap-in force; phenomenons such as often can coming off or flick; not only affect work efficiency;, there is potential safety hazard in the risk of bringing out in addition Secondary Circuit of Potential Transformer short circuit.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model provides a kind of Novel site tester voltage compression bonding apparatus, its technical scheme of taking is: comprise housing, be located at respectively screw jack and voltage jack on housing front panel, and be located at respectively fixed screw and the voltage contact in housing, screw jack and fixed screw are corresponding two groups, lay respectively at the left and right sides of housing, each fixed screw is inserted in corresponding screw jack, voltage jack and voltage contact are corresponding four groups, the front end of every phase voltage contact is fixed on corresponding voltage jack, the front and rear part of every phase voltage contact is respectively cylindrical conductor, they fix by the spring that is positioned at middle part, on every phase voltage contact, cover has corresponding sheath.
The installation site of the utility model fixed screw is corresponding with electric energy meter tail screw-socket position, fixed screw is screwed to the firm installation that electric energy meter tail can implement device when Watt-hour meter's field test.Voltage contact adopts the form of cylindrical conductor afterbody welding spring, can realize on the one hand voltage contact and firm contact of showing between the voltage screw of tail, thereby effectively realize voltage acquisition after device is installed to electric energy meter tail; Voltage contact selects column formula also can increase as much as possible contact resistance on the other hand, improves the accuracy of measuring.Voltage socket is for connecting the pressure-wire of electric energy meter on-site calibrator, and the information of voltage that the collection of voltage contact is come passes to tester.Sheath is fixed on each voltage contact, plays the effect of protection voltage contact, can effectively prevent in checking procedure each voltage contact caused phase fault of colliding.
The utility model can thoroughly avoid voltage in the process of Watt-hour meter's field test to press from both sides the problem coming off, and has good reliability, feature that measuring accuracy is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, screw jack 2 and voltage jack 3 are located at respectively on housing 1 front panel, and fixed screw 4 and voltage contact 5 are located at respectively housing 1.Screw jack 2 and fixed screw 4 are corresponding two groups, lay respectively at the left and right sides of housing 1, and each fixed screw 4 is inserted in corresponding screw jack 2.Voltage jack 3 and voltage contact 5 are corresponding four groups, the front end of every phase voltage contact 5 is fixed on corresponding voltage jack 3, the front and rear part of every phase voltage contact 5 is respectively cylindrical conductor, they fix by the spring 6 that is positioned at middle part, and on every phase voltage contact 5, cover has corresponding sheath 7.
In the process of Watt-hour meter's field test, only fixed screw 4 need be tightened to the screw-socket of electric energy meter tail, voltage contact 5 will gather the information of voltage of tested electric energy meter by automatic impaction on the voltage contact of table tail, then the voltage jack 3 of the pressure-wire insertion apparatus of tester can will be obtained to required voltage information.
