Abstract
The utility model discloses a power supply switching control system which is provided with a dual-path three-phase alternating current input terminal. The connected power supply in each path is processed by an independent finishing unit, and then a rectifying unit power supply output terminal outputs power supplies in two paths. Each output direct-current power supply is transmitted to an electrical device after passing a control module and a power supply output module. The system can carry out the automatic control and realize the rapid manual switching in an emergency situation, so the reliability is high, and the device protection EMC industrial anti-interference level can reach to the fourth level. The system has the time-delay adjusting function and the simulation state display function, and the circuit is simple and the manufacturing cost is low. At the same time, the system is strong in versatility, can be applied to the dual-path three-phase four-line alternating commercial power, the dual-path single-phase alternating commercial power, or the dual-path different direct current and alternating current voltage, and can realize the device power supply and the power supply detection and control.

Technical field
The utility model relates to safety supervision system and the special operation equipment etc. of being applied to, power supply switch time can quick joining handover control system.
Background technology
Fast-developing today of each electron trade of changing in modern times, more and more equipments, safety in production, safety monitoring etc. all must round-the-clock work.For example powering-off state can not appear in the production line of automation, steel plant, smeltery, airport safety supervision safety check etc., otherwise the consequence that causes can't be imagined.Though the power supply of two-way really of the equipment that has power supply, in the power supply handoff procedure, can not reach quick joining, and it is very high to possess the power-supply device cost of quick joining function, brings certain economic burden to production firm.
For safety supervision system and special operation equipment etc. when power supply switches; Can cause the terminal equipment that to monitor, control after the outage to work, or another road power supply can not cause the terminal equipment short time power down by quick joining, its outage is caused a lot of negative effects; Terminal equipment and production are caused many injuries; If equipment can not quick joining after outage, gently then loss of data, entail dangers to equipment when serious.
The utility model content
The utility model technical problem to be solved is to realize a kind of switched system that can quick joining when possessing power supply and switching, and this circuit system is simple in structure, low cost of manufacture.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of power supply handover control system; System is provided with two-way three-phase and four-line alternating current input; The power supply that every road is inserted divides two-way output DC source by the rectification unit power output end after independently putting cell processing in order, the DC power supply of output is delivered to power consumption equipment through control module, power supply output module respectively.
Be provided with the signal sampling point between described arrangement unit and the rectification unit power output end, the sampled signal of collection is delivered to sampling unit.
Described control module is provided with two-way control module input, and input DC power exports the power supply output module to through display unit and control unit and by power output end.
The two-way DC power supply of described Input Control Element transfers to outer output through being arranged at the inner diverter switch of control unit.
The advantage of the utility model is that this system can control automatically, also can under case of emergency, can realize manual switchover fast, and reliability is high; The anti-interference level Four that reaches of device protection EMC grade industry; Possess time-delay regulatory function and emulation mode Presentation Function, and circuit is simplified low cost of manufacture.This system's highly versatile can be applied to two-way three-phase and four-line electric main simultaneously, or two-way individual event electric main, or the different combined-voltages of two-way, realizes body apparatus power supply and power supply Detection & Controling simultaneously.

Embodiment
Can the knowledge system be provided with two independent three-phase and four-line alternating current input 1 interface referring to Fig. 1; Every phase current of input is independently done the arrangement Filtering Processing through arrangement unit 2; Afterwards by rectification unit power output end 3 DC power supplys; Sampling unit is done sampling to primary, spare out-put supply respectively; The signal sampling point is arranged between arrangement unit 2 and the rectification unit power output end 3 sampled signal is exported by sampling output 4, and system adopts the EMC Anti-Jamming Technique, guarantees the fail safe and the stability of system.
Can know that referring to Fig. 2,3 the rectification unit power output end 3 of the three-phase four-wire power after two-way is handled is connected with two-way control module input 5 respectively, every DC power supply of input mutually is provided with display unit 6; The employing emulation mode shows; The many usefulness of one key, the state interlocking, two-way input power supply inputs to diverter switch through the external terminal of control unit 7 respectively; Select output one road to the power supply output module, to power devices by diverter switch through power output end 8.
The above-mentioned industrial equipment power supply handoff technique that is applicable to.Device input two-way three-phase and four-line provides power supply and sampling, and two-way is opened into the dry contact input, judges that active and standby side power supply closes the branch state, and for on/off switch provides condition, two-way is left control output, controls active and standby side power supply on/off switch.
Under civilian unidirectional power environment, live wire inserts wherein power supply input, and zero line inserts corresponding zero line position, and through foregoing circuit output equipment power supply, the phase voltage of device input simultaneously provides power supply and sampling; Two-way is opened into the dry contact input, judges that active and standby side power supply closes the branch state, for on/off switch provides condition; Two-way is left control output, controls active and standby side power supply on/off switch.
