Abstract

The application discloses a control method and a structure of hibernation of a control transformer. A comparison current and a no-load operation switch-off time t are set in a PLC logic control module; a plurality of current sensors respectively detect the practical current of control windings and the practical current of illumination windings of a secondary side of the control transformer and send the practical currents to the PLC logic control module, and the PLC logic control module performs statistics of the times T of the control windings and the illumination windings in the practical currents; and the times are compared, and the PLC logic control module selects whether to send signals to a relay module according to a comparison result. According to the control method and the structure of the hibernation of the control transformer, in the condition of satisfying corresponding load and guaranteeing stable power supply by the control transformer, a power supply of a primary side of the control transformer can be switched off during no-load operation, the loss of electric energy in the no-load operation stage of the control transformer is reduced more thoroughly, and more effective energy-saving effect and environmental protection are achieved.

Description

technical field [0001] The present disclosure generally relates to the field of energy-saving control of control transformers, and particularly relates to a sleep control method and structure for control transformers. Background technique [0002] At present, control transformers are widely used in machinery and elevators, which has greatly increased the number of control transformers. At the same time, because the control transformer is designed according to the long-term rated load, but in the actual working environment, it is in the no-load operation state most of the time, resulting in a large amount of power loss. Therefore, the control transformer should pay attention to the problem of energy saving and consumption reduction under the condition of satisfying the corresponding load and ensuring the stability of power supply. [0003] The current main methods for energy saving of control transformers are: 1. Optimizing manufacturing materials to reduce no-load running l...
