New description: [New technology field] The creation of wealth-type electricity (four) from the relay, the chemical 1 can effectively monitor the voltage of the power supply (especially the mains), the voltage value of the whole surface, A voltage-control device that avoids unnecessary power consumption and increases power efficiency. [Prior Art] According to the current power generation and conduction work, most of the alternating current galvanic alternating current, because three-phase power can use less or smaller conductors, rather than multiple single-phase systems that provide the same power, And the three-phase power can also be driven by the fixed torque command (four) drive motor, instead of the single-phase motor pulse torque (four) _ the target has 12 "offset of the same voltage (with global, so in principle, one-way power supply With the application of three-phase power supply, the advantages can be seen: 1. Compared with single-phase rectifier circuit, triple-wing power. - positive muscle circuit has lower continuous wave and higher 2. ^ phase-to-electricity, three The phase power supply can be compared with the private power and the power loss. The flat pressure is tender and the body of the motor and the motor _ generator, large volume, high cost. 3 generators, transformers and motors M392378 4. The three-phase motor can generate the rotating magnetic field by itself, and the single-phase motor must be equipped with the starting coil, so the characteristics of the three-phase motor are better and the efficiency is higher. 5. The three-phase system is composed of a complete single-phase wave, which can be “ Household choice list Phase or two-phase use, so the applicability is relatively high. Therefore, the places with large electricity consumption (such as factories, hospitals, schools, etc.) naturally use high-efficiency three-phase power sources. 22〇v/ll〇v, if using •• three-phase power supply, the county between the phases (UV'VW,·) is 22〇v, if two phases (UV) are taken as single-phase power, The voltage is also 2, but in order to consider the power consumption during the transmission process and the power supply for the user has sufficient voltage, the voltage of each phase (UV, VW, WU) of the three-phase power supply is higher than 220v. However, when the user selects the three-phase power supply or takes two of them to use the single-phase power supply, the user must still convert the higher voltage to a relatively lower low voltage (such as 200~220V); In the process of high and low voltage conversion, the unnecessary loss of power has been caused. This loss will not only be passed on to the user's electricity cost, but also caused waste in terms of the overall power 'resources'. [New content] Therefore, the main purpose of this creation is to provide a kind of power supply (mains power supply). Before entering the user terminal, it detects the voltage change of each phase of the power supply and adjusts it to the appropriate voltage value before use by the user terminal to avoid unnecessary power consumption and improve the power efficiency of the voltage detection control device. 4 M392378 In order to achieve the purpose of the invention, the electric house detection and control system of the present invention comprises: a self-shoe having a plurality of windings, each winding having a primary side and a secondary side respectively having at least two of the three-phase power sources respectively. Connected, the two sides of the two sides are not _ separately pull _, to selectively constitute - phase power output 4 • point # eight * ^ 0 ^, the money axis is still right, the switch is connected to the secondary strip Paste, the electromagnetic switch is activated or not to determine the opening and closing of the relative switch contact; the end and the second: the control of the early element 'separate with the phase of the autotransformer winding power supply output = switch _ _ _ _ _ Each phase of electricity and control of the enemy and the joints _ closed, so that the money (four) of the winding phase: the red end of the wheel end her __, compiled power supply to reduce the voltage, and then sent by the output of each phase power; The detection control unit further includes: a complex phase voltage detection circuit The utility model has an input end and an output end respectively, and the electric 2 system is connected with the phase power output end of each winding of the crane transformer to detect the phase voltage value 'and is converted into a direct current _ and is sent out by the output end; a circuit having a plurality of input terminals and at least an output terminal, wherein each input terminal is respectively connected to a wheel output end of each phase voltage detecting circuit to select one of the phase power M392378 pressure detecting circuit output signals to be sent out by the output terminal; A microprocessor has a plurality of input terminals and a plurality of output terminals, wherein a wheel-in terminal is connected to a multiplex selection circuit; a switching circuit is mainly composed of a driver and a plurality of relays, and the driver is controlled In the microprocessor, each relay has a switch contact, and each switch contact is connected between the electromagnetic switch of the switch group and a power source, so that the microprocessor can pass through the drive and the relay control group. Whether the switch is energized or not. The use of the above circuit design will provide a multi-stage voltage switching function under the premise of ensuring the safety of power consumption. 'When the secondary side of the respective compressor is connected to at least two phases of the input power source respectively', in the starting state, the switch group No action, the three-phase power supply will be sent out from the power supply terminals of the self-light transformer, and the voltage of each phase will be queried by the multiplex selection circuit to the output terminal of each phase voltage detection circuit, and then sent to the micro-processing H-touch, respectively. The Luli device will first determine which phase voltage is the lowest, and then compare the lowest phase voltage with a reference voltage value. If the lowest phase voltage is lower than the reference voltage, the three-phase power supply is directly (four)' higher than The reference voltage value 'employment processing Wei Shi the minimum phase voltage is greater than the benchmark test no bribery, and the switch contacts in the turn-on switch group to switch the phase voltage output of each winding of the self-bribery device Different taps are connected to the secondary side. At this time, each winding becomes a step-down transformer, and the input power is stepped down and then sent to the user terminal; thereby avoiding unnecessary power loss and waste. Normal power supply terminal of the user. It is worth mentioning that the Wei Lizao researched the power supply to perform the buck_break condition, which is based on one of the lowest voltages in the input power supply. (4) Depending on the average value of each phase voltage, : The premise of improving the efficiency of electricity consumption should be ensured in electrical safety. _Electric safety means that the voltage of the input power supply should not be lower than the -safe_limit value. If the electrical threshold value, it will affect the safety of power consumption. Therefore, if the face of each person's dragons is broken, it will be awkward because of the imbalance of the various phases of electricity. In this case, if the average value of each phase voltage is taken as the object of judgment, the average value is obtained.

In implementation, each of the complex phase voltage detection circuits is respectively composed of a transformer, a bridge rectifier and an OPC amplifier. The sub-phase _ sub-division of the above-mentioned phase power supply output terminal # connection 'to obtain their phase-to-phase voltage, and the secondary side of the transformer and the bridge rectifier's input terminal connection 'the phase voltage of the scale test · Cheng Qianlong And then sent to the OP amplifier for signal amplification. a multiplex selection circuit having a plurality of input terminals and at least an output terminal, wherein each input terminal is respectively connected to an output end of each phase voltage detecting circuit, so that an output signal of one phase voltage detecting circuit is sent out from the output terminal In implementation, the multiplex selection circuit is mainly composed of a microcontroller, a multiplexer and an amplifier, and the control number amplifier has a complex person like at least a wheel _, a fresh woven wheel, At least one round of the out-end and - control end 'the rounding end of each phase voltage detecting circuit is connected to the input end of the microcontroller and the multiplexer, and the control end of the multiplexer and the output end of the microcontroller Connecting; thereby, by using the microcontroller to control the switching of the multiplexer, the multiplex switching of each of the pay-for-workers can be alternately sent to the amplifier for the signal-microprocessor, which has a plurality of inputs and a plurality of rounds. One of the rounds is connected to the multiplex selection circuit; in practice, the microprocessor acts as the operational suppression center, which is used to determine the lowest phase of the dragon, and is compared with a set reference value. Microprocessor has complex a plurality of input terminals and a plurality of output terminals, wherein the two input terminals are respectively provided with - a resistance, a slave _ reference voltage value, so as to be compared with the detected voltages of the respective phases, and another input terminal is connected to the aforementioned amplifier , receiving the detected phase voltage signals in φ. The '-switching circuit' is mainly composed of a driver and a plurality of relays, the driver is controlled by a microprocessor, each relay has a switch contact, and each switch contact is respectively connected to the electromagnetic switch of the switch group and a power source. Between the microprocessors and the relays to control the excitation of the electromagnetic switches of the switch group; the drive has a plurality of wheel-in terminals which are respectively connected to the output of the microprocessor and the output of the driver. The terminals are respectively connected with the excitation coils of the relays, and the relay 11 «392378 electric thieves respectively comprise a plurality of switch contacts, and the relay contacts of the respective relays are respectively connected between the electric switches of the switch group and the _ money power supply. So that the microprocessor can control the excitation of the electromagnetic switches of the switch group through the driver and the relay. a power supply circuit for supplying working power to each circuit of the detection control unit and the switch group; in implementation, the power supply circuit includes a transformer, a two-bridge type and a - surface circuit, The view of the second-phase is connected with two phases of each phase of the power supply to obtain a single-phase AC power supply. The single-phase AC power is sent to the input of the two bridge rectifiers by the transformer to reduce the voltage. The DC power supply is rectified by a bridge rectifier to provide a DC power supply with a predetermined amount (such as 2〇4v), and the power supply rectified by the other bridge rectifier is regulated by a steady voltage circuit to provide Multiple sets of DC operating power and reference voltage. Therefore, when the phase input power terminals π, ΐ τ of the primary windings of the autotransformer 11 on the primary side of the windings lu, 112, 113 have power supply, the three-phase power supply is through the winding ends of the windings ', U2, and 113. The taps (U, V, W) are directly sent to the phase power supply output terminals (U, V, W), and the phase voltages of the three-phase power sources are respectively detected by the phase voltage detecting circuit, and the multiplex selection circuit is transmitted through the phase The multiplexer switching between the micro-controller and the multiplexer causes the phase voltages of the three-phase power supply to be sent to the microprocessor in turn for judgment, and the microprocessor will first determine the lowest phase voltage after comparison to determine Whether the phase voltage is greater than the set reference voltage value, if it is equal to or less than the reference voltage value, it indicates that the voltage of each phase of the input voltage 12 M392378 is not high, so there is no loss problem of high voltage to low voltage, so each winding 111, 112 , the normally open switch contact on the secondary side of 113 (1^0?]^07]\/[,]\/0711,1^131) maintains the open circuit, the input three-phase power supply will pass the self-light transformer 11 but It is sent directly without depressurization. However, the detection control unit 13 will continue to monitor the change of the three-phase power supply. When the lowest phase voltage of the three-phase power supply is higher than the reference voltage value set by the microprocessor, the microprocessor is based on the phase voltage. Exceeding the different values of the reference voltage, the switching circuit selects one of the corresponding electromagnetic switches 121, 122, 123, 124 to activate the switch contacts (MFL, MFM, MFH, MR; corresponding to the electromagnetic switch; ^*〇 For example, when the result of the microprocessor operation is that the electromagnetic switch 122 is turned on and the corresponding switch contacts on the secondary sides of the windings 111, 112, 113 are closed, the secondary windings of the respective windings m, 112, 113 are The winding area above (U2W2) is connected to the output of the phase power supply (U, V, W), respectively, thereby achieving the purpose of reducing the voltage of each phase of the three-phase power supply. In the electromagnetic closing 122 conduction and switching contacts (10) ^In the case of closure, because the normally closed switch (MFM) scale is open, (4) the power circuit of other electromagnetic switches 12, 123, 124 is broken, so the independent electromagnetic switch 122 and the switch contact (MFM) are independent. In addition, the aforementioned self-pressure machine can be further Each of the windings is provided with a temperature sense 13 / 8 device 141, 142, 143, each temperature sensor 14 142, 143 and respectively control a normally closed switch contact, each normally closed switch contact is connected in series If the temperature of the voltage-dependent winding of the self-voltage device reaches a predetermined temperature, the normally closed switch contact is turned into an open circuit, and then the signal is sent back to the microprocessor through the optical-light combiner, which is generated by the microprocessor. Warning message or interrupted work. And 'When the voltage side control device of this creation is applied to the three-phase voltage scale of different voltage specifications, it only needs to be in the self-junction u _ electric series terminal (four), phase power output terminal _ and side control A transformer is respectively arranged between the units 13, and the input three-phase power is turned off and then sent to the side control unit 13 for monitoring. The circuit design is designed to ensure the safety of power consumption, and the voltage_control device of the present invention provides - Multi-section voltage switching function, when the primary side of each light transformer is respectively connected with at least two phases of the input t source, in the starting state, the switch group does not operate, and the three-phase power supply is sent out from the power supply terminals of the self-light (four) device, Phase test The multiplex selection circuit inquires each phase f: the output of the detection circuit is detected and sent to the micro-processing, respectively, and the micro-processing H will first touch the lowest one, and then set the lowest phase. The benchmark _ value comparison, if the lowest phase is less than the fresh money, that is, the three reduction of the number of posts, if higher than the wire quasi-recurring value, then the micro-processing n will be recorded to the different levels of the rating of the electricity, M392378 selects the switch contacts in the switch group through the switching circuit, so that the phase voltage output ends of the windings of the autotransformer are switched to different tap connections on the secondary side. At this time, each winding becomes a step-down transformer and will be input. The power supply is stepped down and then sent to the user terminal; thereby not only avoiding unnecessary power loss and waste, but also ensuring normal power supply to the user terminal. It is worth mentioning that the button is determined by the voltage of one of the lowest voltages in the input power source, rather than the average value of each phase voltage. The reason is that the premise of improving the efficiency of electricity consumption should be complicated in the safety of shed electricity. The voltage of the f-safe input power supply should not be lower than the safety threshold. If the voltage is lower than the critical value, it will affect the safety of electricity. Therefore, if we hide the average value of each phase as the touch object, since the voltage of each phase power source may be different due to the imbalance, in this case, if the average value of each phase voltage is taken as the object of judgment, although average The value is higher than the critical value, but when the voltage is adjusted, the voltage of each phase is simultaneously reduced by the same value. Under this condition, the voltage of a certain phase may be lower than the critical value and directly impact the safety of electricity; For the above-mentioned safety reasons, this _ does not make each phase electric _ average _ is the judgment object, and the voltage of one of the phases with the lowest voltage in the input power source is used as the judgment target, in this case, as long as the lowest phase voltage is higher than The reference voltage value, the other phase voltages are two in the reference voltage value, and when the voltage of each phase is adjusted at the same time, there is no problem. 378 某 某 - 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 某 。 。 。 。 。 。 In summary, the author provides a voltage-side control device that is feasible, and the application for a new patent is provided by Mai Law.
