Abstract

The invention discloses a rapid changeover controller of a double-power-source switch. The controller comprises a voltage transformer module, a current transformer module, a voltage limit protection module, an operation amplification module, a low-pass filtering module, a control module, a relay output module, an ON quantity collection module, a display module, a button module, a power source module, a power source end isolation module, a voltage stabilizing module and a grounding end isolation module. According to the invention, the controller can carry out millisecond-level operation via anti-interference treatment in different positions, and the relay output module is used so that the controller can be adapted to different models of changeover switches.

Description

technical field [0001] The invention relates to the technical application field of a dual power switching controller, in particular to a dual power switching fast switching controller. Background technique [0002] The dual power supply controller is mainly used in occasions where the load has high requirements on the continuity of power supply. When one of the power supplies fails, it will quickly switch to the other power supply to ensure the continuity of the load power supply. The dual power supply switching controller automatically realizes the switching of ATS by collecting parameters such as the voltage, frequency, phase, and phase sequence of one (A side) and two (B side) power supplies, and realizes continuous power supply for loads. The switching speed requirements are different. The switching time of traditional dual-power controllers is usually more than 2-3 seconds, which cannot meet the requirements for some occasions that require higher switching time. Conte...
