Abstract

Provided is a three-phase type ring network cabinet secondary phase checking device, comprising a phase checking device housing, LED indicating lamps, a switch and contacts. The phase checking device housing is a square three-dimensional structure; the contacts comprise contact A1, contact B1, contact C1, contact A2, contact B2, and contact C2; the LED indicating lamps comprise lamp L1, lamp L2, lamp L3, lamp L4, lamp L5, and lamp L6; the LED indicating lamps are arranged on the front surface of the phase checking device housing in two rows and three columns; one side of the phase checking device housing is provided with the contact A1, contact B1, and contact C1, and the other side of the phase checking device housing is provided with the contact A2, contact B2, and contact C2; the phase checking device housing is internally provided with a phase checking device which is in connection with the contacts, the switch and the LED lamps. The invention also discloses a phase checking method utilizing the three-phase type ring network cabinet secondary phase checking device. The device and method can directly observe which phase breaks down, enhance phase checking accuracy, and greatly simplify operation.

Description

technical field [0001] The invention relates to the technical field of power system power distribution engineering, in particular to a secondary phase checking device of a three-phase ring network cabinet and a phase checking method thereof. Background technique [0002] Phase verification refers to the approval of the phase sequence of two power sources or loops in the power system to ensure that the three-phase phase sequence of the entire system is unified. The wrong phase sequence is very harmful. Parallel operation will cause serious short-circuit accidents, burn out transformers, and cause serious consequences such as motor reversal, electrical damage, and meter measurement failure. Therefore, the relevant operation and management requirements of the power system clearly stipulate that all work involving new, rebuilt, expanded or changed lines and substations (distribution) must be verified after the work is completed. [0003] According to the position of the nuclear...
