(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a generation device for automatic switching of main and standby power supplies comprises a main and standby power supply, a relay and a power load, wherein the relay is provided with two auxiliary outputs CJ-1 and CJ-2, each path of relay is provided with two groups of contacts of normally open and normally closed contacts, a relay coil CJ is powered by a main power supply, the main power supply is connected with a normally open contact of the auxiliary contacts of the relay, and the standby power supply is connected with a normally closed contact of the auxiliary contacts of the relay.
Preferably, the device can realize that when the main power supply is normally supplied, the main power supply is preferentially selected to supply power to the power load.
Preferably, when the main power supply stops supplying power, the main power supply is automatically switched to the standby power supply, and when the main power supply resumes supplying power, the main power supply is switched to the standby power supply again, so that the method is suitable for power utilization scenes with power supplied by the standby power supply.
Preferably, the electric load may be any electric device.
(III) advantageous effects
The utility model provides a generating device of activestandby power automatic switch-over. The method has the following beneficial effects:
the utility model provides a generating device for automatically switching the main power supply and the standby power supply, which can preferentially select the main power supply to supply power to a power consumption load when the main power supply is normally supplied; when the main power supply stops supplying power, the standby power supply is automatically switched to, and when the main power supply recovers to supply power, the main power supply is switched to again, so that the power utilization scene with the power supplied by the main power supply and the standby power supply is suitable.
Drawings
Fig. 1 is a schematic view of an embodiment of the apparatus of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a technical solution: a kind of generator that the main and standby power supplies switch over automatically, including main and standby electricity, relay and power consumption load, the said relay has two-way auxiliary output CJ-1 and CJ-2, and each way has two sets of contacts of normally open, normally closed, the said relay coil CJ is powered by the main power supply, the said main power supply inserts the normally open contact of the auxiliary contact of the relay, the said standby power supply inserts the normally closed contact of the auxiliary contact of the relay, the apparatus can realize when the main power supply supplies power normally, the main power supply of preferential selection supplies power to the power consumption load; when the main power supply stops supplying power, the standby power supply is automatically switched to, and when the main power supply recovers to supply power, the main power supply is switched to again, so that the power utilization scene with the power supplied by the main power supply and the standby power supply is suitable.
The device can realize that when the main power supply is normally supplied, the main power supply is preferentially selected to supply power to the power utilization load, so that the main power supply can be normally supplied under normal conditions, and the main power supply is preferentially selected to supply power to the power utilization load, thereby ensuring the normal operation of the device.
