Abstract

The invention provides an intelligent wiring device and examination method for online test of a gateway electric energy metering device, and solves the problems that frequent opening (closing) of contacts of a conjunction box in a present gateway electric energy metering device causes no-voltage and shunting faults and influences the gateway metering accuracy, and manual test via multiple devicesin multiple points causes high workload, low efficiency and high safety risk.

Description

technical field [0001] The invention relates to the field of electric energy metering, in particular to an intelligent wiring device and inspection method for on-line testing of an electric energy metering device at a gateway. Background technique [0002] The on-site test of the electric energy metering device at the gateway mainly involves the operation error test of the gateway meter, the secondary voltage drop test of the voltage transformer, and the secondary load test of the transformer. At present, the secondary circuit of the transformer for gate metering is mostly equipped with a joint junction box for electric energy measurement (hereinafter referred to as "junction box"), which is only used for the electrical connection and switching of the secondary circuit for metering, and has no other functions such as testing. The electric energy meter field tester can be connected to the secondary circuit through the split (close) connection to complete the test of the opera...
