Three-phase intelligent watt-hour meter inspection device and method

The invention relates to a watt-hour meter inspection device and method, in particular relating to a three-phase intelligent watt-hour meter inspection device and method. The existing watt-hour inspection device has long inspection time, and needs an extra instrument for inspecting the power consumption of a watt-hour meter; the existing watt-hour meter inspection device has low efficiency and can inspect only one watt-hour meter for one time; and in addition, the existing watt-hour meter inspection device is inability of testing the cost-control trip of the intelligent watt-hour meter. The three-phase intelligent watt-hour meter inspection device comprises a standard clock, a three-phase program-controlled source, a standard watt-hour meter, error calculators, power consumption testers and a communication module. The inspection device provided by the invention is characterized by comprising trip monitoring units, wherein the inspection device has a plurality of testing work positions; one power consumption tester, one trip monitoring unit and one error calculator are arranged on each testing work position; each error calculator is provided with a counting calculation module; and the standard watt-hour meter is used for metering an output module. The three-phase intelligent watt-hour meter inspection device is rapid in inspecting watt-hour meters, and can inspect the power consumption and the cost-control trip.
