A kind of watt-hour meter is tested the table platform
Technical field
The utility model relates to a kind of watt-hour meter and tests the table platform, is applicable to check simultaneously two watt-hour meter.
Background technology
The manufacturer of electron watt-hour meter is different, and quality is uneven, card word phenomenon often occurs, even the ammeter that has occurs walking fast or walks slow phenomenon, going wrong all is directly to change at the scene table, and wherein the failure cause of some table is unclear, causes the manpower and materials waste.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly can test the table platform by the on-the-spot watt-hour meter that uses.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of watt-hour meter is tested the table platform, it is characterized in that: comprise power switch, on-load switch and latch plate; The upper end connecting power line of described power switch, lower end connect wire and according to the position of watt-hour meter input terminal connector lug are set at wire end; The upper end of described on-load switch connects wire and according to the position of watt-hour meter lead-out terminal connector lug is set at wire end, and the lower end of on-load switch is by wire connecting bolt plate.
The further improvement that the utility model is done is: also comprise deck plate, connector lug and wire, power switch, on-load switch and the latch plate of two watt-hour meter can be installed the setting of described deck plate.
The beneficial effect that adopts technique scheme to produce is: simple in structure, easy to carry, swift to operate.Two watt-hour meter are detected at the scene simultaneously, judge whether to change watt-hour meter according to testing result, use manpower and material resources sparingly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the circuit connection diagram that a kind of watt-hour meter of the utility model is tested the table platform.
As shown in Figure 1: 1 power switch, 2 on-load switches, 3 deck plates, 4 watt-hour meter, 5 latch plates.
Embodiment
Contrast Fig. 1 uses step to be described further to operation of the present utility model: a kind of watt-hour meter is tested the table platform, comprises power switch 1, on-load switch 2 and latch plate 5; The upper end connecting power line of described power switch 1, lower end connect wire and according to the position of watt-hour meter 4 input terminals connector lug are set at wire end; The upper end of described on-load switch 2 connects wire and according to the position of watt-hour meter 4 lead-out terminals connector lug is set at wire end, and the lower end of on-load switch 2 is by wire connecting bolt plate 5.Also comprise deck plate 3, at described deck plate 3 connector lug and wire, power switch 1, on-load switch 2 and the latch plate 5 that two watt-hour meter 4 can be installed is set.
During on-the-spot the use, the watt-hour meter 4 of preparing to detect is installed on the deck plate 3, after finishing, connection plugs electrical appliance at plug housing 5, according to the frequency of pulse in the fixing load current inspection sheet bit time and the number of degrees of walking, judge and to use according to the accuracy of institute's electrical verification kilsyth basalt 4, determine whether to change again watt-hour meter.
