An embodiment of the utility model provides a three-phase
refrigeration socket phase sequence
verification device, which comprises a measurement box, a phase sequence meter, wiring terminals, a connecting lead and a three-phase
refrigeration plug, the three wiring terminals L1, L2 and L3 are fixedly installed in the measurement box, the phase sequence meter is fixedly installed on a panel of the measurement box, a measurement result observation surface of the phase sequence meter is arranged outwards, and the three wiring terminals L1, L2 and L3 are fixedly installed on the panel of the measurement box. Three measuring leads L1, L2 and L3 of the phase sequence meter are correspondingly connected and fixed on three wiring terminals L1, L2 and L3, the three-phase
refrigeration plug is matched with a refrigeration socket to be tested, and three pins L1, L2 and L3 of the three-phase refrigeration plug are correspondingly connected and fixed on the three wiring terminals L1, L2 and L3 through connecting wires respectively. According to the embodiment of the utility model, the phase sequence
verification process is simplified from the original seven processes to three processes, so that the
verification efficiency is effectively improved, the
electric shock condition is avoided, and the safety of verification personnel is ensured on the premise of ensuring the verification precision.
