Abstract

The utility model discloses a double-configuration relay protection verification auxiliary apparatus, comprising a housing, a current loop serial module and a voltage loop parallel module, wherein the current loop serial module and the voltage loop parallel module are arranged in the housing. Facts that current loops of two sets of relay protection apparatuses are connected in a current loop of a test instrument in series and voltage loops of the two sets of the relay protection apparatuses are connected in a voltage loop of the test in instrument in parallel, that the test interment inputs alternating quantity to the two sets of the relay protection apparatuses, that then the two sets of the relay protection apparatuses have current and voltage inputs at the same time, and that the two sets of the relay protection apparatuses can be verified at the same time are effectively achieved. Compared with a previous verification method, time for verifying relay protection apparatuses is shortened greatly, working efficiency is improved, time of line outage is shortened, comparison of performance parameters of the two sets of the relay protection apparatuses is enabled at the same time, and accuracy of verification results is guaranteed.
