| description | The utility model discloses a switching loop capable of improving power supply reliability, which is provided with a working section power supply and a security section power supply which are jointly connected with an automatic switching device, and a power supply control switch, a first power supply monitoring relay and a UPS (Uninterrupted Power Supply) host are arranged between the automatic switching device and the working section power supply. The UPS host is externally connected with a storage battery, a second power supply control switch and a second power supply monitoring relay are arranged between the security section power supply and the automatic switching device, after the working section power supply is powered off, the UPS host controls the external storage battery to continuously supply power to the load and give an alarm, and stable voltage is maintained within a certain period of time; therefore, power failure is avoided during switching of the working section power supply and the security s |
