The regulator includes a common regulator circuit, a separate output circuit and an automatic control circuit, the regulator circuit includes three separate single phases regulator circuit corresponding to the three-phase power supply. The separate output circuit includes three contactors; the major contacting heads of three contractors respectively are connected with the joint of the regulator circuit output terminals and loads. The regulator circuit input is connected with the power supply via the three-phase switch. When one of the power supplies fails, the regulator only cuts off the failed ones. The non-failure circuit works normally. When the failure is removed, the regulator recovers the automatic output. The utility model is applicable to the reform on regulators, e.g. parameter regulator, mechanical voltage adjustment compensation regulator, induction voltage regulator and new silicon controlled contactless rectification regulator.

Technical field
The utility model relates to the electric power voltage stabilizers with three single-phase difference output functions.
Background technology
The three-phase power voltage regulator of widespread usage in the electric system; three-phase four-wire system is adopted in its input and output usually; load can be that three-phase (3 Φ 380V) also can be single-phase (220V); in order to prevent to burn the three-phase consumer because of the power supply phase shortage causes single-phase operation; output end of voltage stabilizer is equipped with automatic protection functions; both when electrical network is a certain when breaking down mutually: as a certain outage (phase shortage) mutually; overtension or low excessively (surpassing voltage stabilized range); overburden operation (overload) etc.; though be that a certain of power supply broken down mutually; voltage stabilizer is all wanted the execute protection function; disconnect the output contactor and cut off three-phase supply simultaneously, prevent that the three-phase consumer from damaging because of single-phase operation.
But some power utilization environments are arranged, cut off three-phase output simultaneously and there is no need, as: the voltage stabilizer load is single-phase electric devices, as private residence building, office building etc.; Though the consumer that has is the three-phase supply input, but when power supply lacks one mutually even lack two phase times and do not influence equipment and normally move, as in electricity consumption places such as communication base station, microwave base station, telecommunications room, input to the Switching Power Supply cabinet by three-phase supply, by the Switching Power Supply cabinet backward a level consumer provide direct supply simultaneously to batteries charging, when phase-deficient operation, do not influence equipment operation.Under above-mentioned power utilization environment the open-phase protection function not the heart want, if just greatly reduce like this continuity and the reliability of power supply, thus in sum, three-phase power voltage regulator of the prior art exist can not phase-splitting the defective of output separately.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of three single-phase electric power voltage stabilizers of output function respectively that have are provided, when a phase or two-phase break down in the three-phase supply, a voltage stabilizer disengagement failure is exported mutually, non-fault still can keep voltage stabilizing output mutually, when fault recovers just often can recover automatically three-phase voltage stabilizing output mutually.
The technical scheme that the utility model adopted is: the utility model comprises common mu balanced circuit, difference output circuit and automatic control circuit, described mu balanced circuit comprises three single-phase mu balanced circuits of independence of corresponding three-phase supply, described output circuit respectively comprises three contactors, the main contact of three described contactors is connected on respectively between three the single-phase circuit output end of pressure-stabilizing of independence and load of described mu balanced circuit, and the input end of described mu balanced circuit is connected with power supply by threephase switch.
Described control circuit comprises the coil of o controller and three described contactors, described o controller comprises KA, KB, three pairs of output of KC control interface, and described KA, KB, three pairs of output of KC control interface correspondence respectively are connected in the coil and control electric power loop of three described contactors.
The beneficial effects of the utility model are: because the utility model comprises common mu balanced circuit, difference output circuit and automatic control circuit, described mu balanced circuit comprises three single-phase mu balanced circuits of independence of corresponding three-phase supply, described output circuit respectively comprises three contactors, the main contact of three described contactors is connected on respectively between three the single-phase circuit output end of pressure-stabilizing of independence and load of described mu balanced circuit, the input end of described mu balanced circuit is connected with power supply by threephase switch, described control circuit comprises the coil of o controller and three described contactors, described o controller comprises KA, KB, three pairs of output of KC control interface, described KA, KB, three pairs of output of KC control interface correspondence respectively is connected in the coil and control electric power loop of three described contactors, so the utility model is a kind of three single-phase electric power voltage stabilizers of output function respectively that have, when a phase or two-phase break down in the three-phase supply, this voltage stabilizer disengagement failure is exported mutually, non-fault still can keep voltage stabilizing output mutually, recover just often can recover automatically three-phase voltage stabilizing output mutually when fault, improved the continuity and the reliability of power supply.
