Problems solved by technology
[0002] With the increase of power consumption, the load of the power generation system of the power company can no longer meet the needs of the power consumption of the power consumer, resulting in the power generation system of the power company often tripping due to the overload of power consumption, which is very easy to damage electrical products
[0003] At present, in order to save costs, factories and enterprises generally adopt single power supply control. When the single power supply is cut off, the equipment will not operate normally, production will be shut down, and the equipment may be stuck, which will bring certain economic benefits to factories and enterprises. Loss, the traditional dual power supply control is generally switched by pressing the switch. The delay time of pressing is longer, which will cause voltage sag and short-term power failure, which is easy to affect the quality of electric energy and has low applicability.

Embodiment Construction
[0026] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.
[0027] refer to Figure 1-6 , a power-off automatic switching power supply device, comprising a mounting plate 1 and a housing 17 matching the mounting plate 1, slide grooves 14 are provided on both side walls of the mounting plate 1, and the lower side walls of the housing 17 are provided with Through groove 18 is arranged, and the both side walls of through groove 18 are provided with the flanging 19 that matches with the size and position of chute 14, and housing 17 is installed by sliding in chute 14 by flanging 19, effectively It reduces the accumulation of dust falling on the mounting plate 1, and setting the through groove 18 facilitates the smooth passage of the components on the mounting plate 1 when the housing 17 is installed, and at the same time facilitates ventilation on both sides to ensure heat dissipation.
[0028] The mounting plate 1 ...

The invention discloses a power-off automatic switching power supply device, which comprises a mounting plate and a housing matched with the mounting plate, a main power supply and a standby power supply are arranged on the mounting plate, and a Switch agencies. The advantage is that the present invention magnetically adsorbs the permanent magnets after the two electromagnets are energized, and adjusts the size through the current regulator to realize the movement of the permanent magnets and the moving rod. When the main power supply fails, the magnetic adsorption of the electromagnets to the permanent magnets And the moving rod moves to the backup power supply, and then completes the connection between the electrical contact and the electrical contact end, thereby completing the automatic switching from the main power supply to the backup power supply. Driven by magnetic force, the switching speed is fast, avoiding the high delay of the traditional push switch, and the structure is stable. Guaranteed power quality.
Description
technical field [0001] The invention relates to the technical field of power supply control, in particular to an automatic switching power supply device when power is off. Background technique [0002] With the increase of electricity consumption, the load of the power generation system of the power company can no longer meet the needs of the electricity consumption of the power consumer, so that the power generation system of the power company often trips due to the overload of electricity consumption, and it is easy to damage the electrical products. [0003] At present, in order to save costs, factories and enterprises generally adopt single power supply control. When the single power supply is cut off, the equipment will not operate normally, production will be shut down, and the equipment may be stuck, which will bring certain economic benefits to factories and enterprises. Loss, the traditional dual power supply control is generally switched by pressing the switch. The...
