Abstract
The utility model relates to the field of UPS power supplies, and particularly to a self-recovery device for UPS output fault. The self-recovery device for UPS output fault comprises the following components: a UPS power supply, a standby power supply, back-stage equipment, a detecting unit and an actuating mechanism; wherein the UPS power supply and the standby power supply are AC power supplies. The actuating mechanism comprises a first contactor and a second contactor. The first contactor and the second contactor respectively comprise a coil, a main contact and an auxiliary contact. The detecting unit comprises a relay which comprises a coil, a normally open contact and a normally closed contact. The self-recovery device for UPS output fault can quickly switch to the standby power supply when UPS output fault is detected, thereby ensuring normal operation of back-stage equipment. After the UPS output fault is settled, the self-recovery device can quickly recover to power supply by the UPS power supply, thereby settling a technical problem that the back-stage equipment cannot operate normally when UPS power supply fault occurs in the existing device.

Utility model content
Technical problem to be solved in the utility model is to provide a kind of when ups power breaks down, can automatically switch to stand-by power supply, after ups power output fault is got rid of, can automatically restore to ups power power supply, guarantee the device of the normal operation of rear class equipment.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
UPS output fault self-resetting devices, comprises ups power, stand-by power supply, rear class equipment, detecting unit and actuator, and wherein, ups power and stand-by power supply are AC power; Described actuator comprises contactor one and contactor two, and described contactor one and contactor two include coil, main contacts and auxiliary contact, and described detecting unit comprises relay, described relay pack vinculum circle, normally opened contact and normally-closed contact; Described relay coil is in parallel with ups power output, and ups power output is connected with contactor one main contacts and rear class equipment connection, and stand-by power supply is connected in series rear and rear class equipment connection with contactor two main contactss; Relay normally open contact, contactor two auxiliary contact and contactor one coil are connected successively, relay normally open contact is connected with ups power output live wire, contactor one coil is connected with ups power output zero line, relay normally-closed contact, contactor one auxiliary contact and contactor two coil are connected successively, relay normally-closed contact is connected with stand-by power supply live wire, and contactor two coil is connected with stand-by power supply zero line.
Further, in order to detect the output situation of UPS output three phase mains, described relay comprises relay one, relay two and relay three, and relay one, relay two and relay three include coil, normally opened contact and normally-closed contact; The coils from parallel connection of coils of relay one, relay two and relay three, after the normally opened contact series connection of relay one, relay two and relay three, one end is connected with ups power output live wire, the other end is connected with contactor two auxiliary contact, after the normally-closed contact parallel connection of relay one, relay two and relay three, one end is connected with stand-by power supply live wire, and the other end is connected with contactor two coil.
Principle of the present utility model:
Generally, this device is from ups power output power supply, by relay one, the detecting unit that relay two and relay three form detects respectively the three-phase of ups power output, when three phase mains any occurs power-off or when under-voltage mutually, by relay one, the down circuitry that the normally opened contact of relay two and relay three is together in series, the main contacts of contactor one is disconnected, the auxiliary contact of contactor one are closed, by relay one, the circuit that the normally-closed contact of relay two and relay three is together in parallel obtains electric, contactor two main contacts adhesives, device is switched to stand-by power supply output.
When ups power recovers normal, the circuit dead electricity being together in parallel by the normally-closed contact of relay one, relay two and relay three, contactor two main contacts dead electricity disconnect, stand-by power supply stops output, contactor two auxiliary contact adhesives simultaneously, contactor one main contacts obtains electric adhesive, and ups power restores electricity.
