Abstract
The utility model discloses a control device for a self-contained power supply. Phases A, B and C of a public three-phase power supply and three phases a, b and c of a self-contained three-phase power supply are respectively connected with different inlet phases of a two-direction switch QS; and a load switch QL is connected to the phases a, b and c of the self-contained power supply. The control device is characterized in that an electric load FZ is connected with the outlet phase of the two-direction switch QS through a universal circuit breaker QA; a control circuit breaker K1 is connected in series with a middle relay coil J and then is connected with two phases of a three-phase power supply; a high-power contactor main contact KM1 is connected to the three phases a, b and c of the self-contained power supply; and a high-power contactor coil KM and a high-power contactor auxiliary normally open contact KM2 are connected in parallel with each other, then are connected in series with a control circuit breaker K2, a middle relay normally closed contact J1 and a universal circuit breaker normally open contact QA1 are finally connected with two of the three phases a, b and c of the self-contained three-phase power supply. The control device has the characteristics that the shortcoming that the conventional self-contained power supply adaptation system cannot automatically cut off power is overcome; after a public power grid is switched on, the self-contained power supply is automatically and timely cut off; and a phenomenon that the self-contained power supply continuously supplies power after the public power grid is switched on is avoided.
Description
Technical field
The utility model belongs to power supply and send the power-down control device technical field, especially relates to a kind of power autonomous control device.
Background technology
Tradition is power autonomous through on-load switch, isolating switch, to the power consumption equipment power supply, behind the public electric wire net incoming call; Have only through manual work and utilize indicator light or electric bell perception, artificial then cut off power autonomous, shortcoming be if operating personnel not at the scene or personnel tired; Just be not easy perception; Cause power autonomous still continuation the in public electric wire net incoming call back to generate electricity, can not in time cut off, cause great energy waste.
Summary of the invention
The purpose of the utility model overcomes shortcoming, the public electric wire net incoming call back that traditional power autonomous distribution system can not cut off the power supply automatically and in time cuts off power autonomous, as to prevent the power autonomous continuation power supply in public electric wire net incoming call back power autonomous control device automatically providing a kind of with the deficiency of improving prior art.
The purpose of the utility model is to realize like this; A kind of power autonomous control device; Be A, B, C phase, a that provides three phase mains for oneself, b, the c three-phase of public three phase mains connect respectively two-direction switch QS different advance phase; Provide for oneself on a, b, c three-phase of three phase mains and be connected to on-load switch QL; Be characterized in connecing through universal circuit breaker QA the phase that goes out of two-direction switch QS with electric loading FZ; Connect wherein two phases of three phase mains behind the control circuit breaker K1 serial connection auxiliary relay coil J, be connected to high-power contactor main contacts KM1 on a of three phase mains, b, the c three-phase providing for oneself, series connection is controlled circuit breaker K2, auxiliary relay break contact J1, universal circuit breaker make contact QA1 and is connect two in a that provides three phase mains for oneself, b, the c three-phase mutually after high-power contactor coil KM and the auxiliary make contact KM2 parallel connection of high-power contactor.
Compared with present technology the utility model has following distinguishing feature and good effect: the utility model adopts and meets going out mutually of two-direction switch QS with electric loading FZ through universal circuit breaker QA; Connect wherein two phases of three phase mains behind the control circuit breaker K1 serial connection auxiliary relay coil J; Be connected to high-power contactor main contacts KM1 on a of three phase mains, b, the c three-phase providing for oneself, series connection control circuit breaker K2, auxiliary relay break contact J1, universal circuit breaker make contact QA1 connect two in a that provides three phase mains for oneself, b, the c three-phase mutually after high-power contactor coil KM and the auxiliary make contact KM2 parallel connection of high-power contactor, through utilizing auxiliary relay perception public electric wire net incoming call; Control high-power contactor; Cut off power autonomous, after public electric wire net has a power failure, the generating of house generator group; Behind the public electric wire net incoming call; Automatically cut-out is power autonomous, and the utility model can overcome the shortcoming that traditional power autonomous distribution system can not be cut off the power supply automatically, and public electric wire net incoming call back auxiliary relay gets the electronic high-power contactor that cuts off; Automatically in time cut-out is power autonomous, prevents the power autonomous continuation power supply in public electric wire net incoming call back; Compare with the power autonomous manual operation control system of tradition, the advantage of the utility model mainly contains following two aspects: the one, reduce wear and tear in machines, and prolong service life of a machine, save the energy; The 2nd, two kinds of protection chain functions promptly be electrically connected lock and mechanical chain are arranged, can prevent effectively that self power generation from pouring public electric wire net into and causing significant damage.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
Embodiment; A kind of power autonomous control device; With reference to Fig. 1; Be A, B, C phase, a that provides three phase mains for oneself, b, the c three-phase of three phase mains connect respectively two-direction switch QS different advance phase, connect the phase that goes out of two-direction switch QS with electric loading FZ through universal circuit breaker QA, provide for oneself on a, b, c three-phase of three phase mains and be connected to on-load switch QL; Connect wherein two phases of three phase mains behind the control circuit breaker K1 serial connection auxiliary relay coil J; Be connected to high-power contactor main contacts KM1 on a of three phase mains, b, the c three-phase providing for oneself, series connection control circuit breaker K2, auxiliary relay break contact J1, universal circuit breaker make contact QA1 connect two in a that provides three phase mains for oneself, b, the c three-phase mutually after high-power contactor coil KM and the auxiliary make contact KM2 parallel connection of high-power contactor, and this constitutes a kind of structure of the utility model.
