Embodiment Construction
[0012] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0013] A type aging process of a three-phase electric meter, characterized in that the steps of the aging process are as follows:
[0014] (1) Safely and reliably hang the three-phase ammeter that needs to be aging on the aging table;
[0015] (2) Connect the live wire and neutral wire of the three-phase electric meter to the live wire and neutral wire connectors on the burn-in station respectively;
[0016] (3) Turn on the power switch of the aging station, adjust the voltage to 220V, and stabilize for 15 minutes;
[0017] (4) Set the current of the aging station to Imax, 200%Ib, 100%Ib, 10%Ib, 5%Ib;
[0018] (5) When the counter goes back to 0, observe that the operation of each three-phase electric meter should be normal, and the movement should be correct...

The invention relates to a three-phase electric meter counting aging technology. The three-phase electric meter counting aging technology is characterized by comprising the following steps: safely and reliably hanging a three-phase eclectic meter in need of counting aging on an aging bench; respectively connecting the live line and the zero line of the three-phase eclectic meter with a live line joint and a zero line joint on the aging bench; switching on the power switch of the aging bench, and adjusting a voltage to be 220 V for stabilized 15 minutes; respectively setting the currents of the aging bench to be at an Imax, 200%Ib, 100%Ib, 10%Ib and 5%Ib shift for counting; when a meter walks to return to zero, it is observed that the operation of the three-phase eclectic meter should be normal and counting should be correct; and switching off the power supply of the aging bench, and removing the three-phase eclectic meter. According to the invention, through improving conventional counting aging technology, the counting stability of the three-phase eclectic meter can be guaranteed, and the reliability and practicality of the three-phase eclectic meter are ensured.
Description
