As described above, since the power supply in the automatic transfer switch can select different output voltages, the switching assembly needs to be matched with different energy storage motors under the condition of different output voltages to avoid damage to the energy storage motors due to overvoltage, so that alternative models of the energy storage motors are increased. Embodiments of the present disclosure provide a switching assembly 10 for an energy storage motor 20 that requires only one energy storage motor 20. Hereinafter, the principles of the present disclosure will be described with reference to fig. 1.
Fig. 1 illustrates a schematic diagram of an automatic transfer switch 100, in which an actuator (not shown) is not shown, according to some embodiments of the present disclosure. As shown in fig. 1, the switching assembly 10 described herein generally includes a power supply 1, a switching section 2, a buck current limiting section 3, a power supply selecting section 4, a micro control unit 5, and an input section 6. The power supply 1, the power supply selection part 4, the switch part 2, the step-down current limiting part 3, the energy storage motor 20 and the power supply 1 form a loop.
With continued reference to fig. 1, in some embodiments, the power source 1 is mainly used for supplying power to the energy storage motor 20, wherein the power source 1 includes a main power source 11 and a standby power source 12, a first end of the main power source 11 and a first end of the standby power source 12 are respectively connected to one end of the energy storage motor 20, a second end of the main power source 11 and a second end of the standby power source 12 are respectively connected to the switching component 2, and the switching component 2 is electrically connected to the other end of the energy storage motor 20. One of the main power supply 11 and the standby power supply 12 is connected to a circuit, that is, one of the main power supply 11 and the standby power supply 12 supplies power to the energy storage motor 20.
With continued reference to fig. 1, in some embodiments, the power supply selection unit 4 is located between the second end of the main power supply 11 and the second end of the standby power supply 12 and the switching unit 2, specifically, the input end of the power supply selection unit 4 is electrically connected to the second end of the main power supply 11 and the second end of the standby power supply 12, and the output end of the power supply selection unit 4 is electrically connected to the switching unit 2. The output of the micro control unit 5 is electrically connected to the power supply selection part 4. The micro control unit 5 may detect the states of the main power source 11 and the standby power source 12, and the micro control unit 5 may control the power source selecting part 4 to select the main power source 11 or the standby power source 12 to be connected to the circuit, so that one of the main power source 11 and the standby power source 12 in a better state supplies power to the energy storage motor 20.
The power supply selection part 4 according to the embodiment of the present disclosure may be various types of power supply selection parts 4 currently known or available in the future, and the embodiment of the present disclosure is not limited thereto. For example, in some embodiments, the power supply selection component 4 may be a relay. In other embodiments, the power selection component 4 may be a thyristor.
With continued reference to fig. 1, in some embodiments, the switch component 2 includes a tap lever 21, a first contact 22, and a second contact 23, the tap lever 21 being capable of electrically connecting with either the first contact 22 or the second contact 23. The first contact 22 and the second contact 23 are electrically connected to the other end of the energy storage motor 20, i.e. the first contact 22 or the second contact 23 can be selected to be connected into the circuit by electrically connecting the toggle lever 21 with the first contact 22 or the second contact 23.
With continued reference to fig. 1, in some embodiments, the input of the micro-control unit 5 is capable of receiving a set voltage signal for indicating a set voltage, so that the micro-control unit 5 controls the main power supply 11 or the standby power supply 12 to output at the set voltage according to the set voltage signal. The output of the micro control unit 5 is electrically connected to the switching member 2. In case that the set voltage signal exceeds the operating voltage range of the energy storage motor 20, the micro control unit 5 controls the tap lever 21 and electrically connects the tap lever 21 with the first contact 22. And in case the set voltage signal is within the operating voltage range of the energy storage motor 20, the tap lever 21 is electrically connected with the second contact 23 under the control of the micro control unit 5.
It will be appreciated that a buck current limiting member 3 is provided between the first contact 22 and the energy storage motor 20. The step-down current limiting member 3 can regulate the input voltage of the energy storage motor 20, thereby protecting the energy storage motor 20. Specifically, in the case that the set voltage signal is within the operating voltage range of the energy storage motor 20, since the tap lever 21 is electrically connected to the second contact 23, the step-down current limiting member 3 is not electrically connected to the energy storage motor 20, so that the main power source 11 or the standby power source 12 directly supplies power to the energy storage motor 20. Under the condition that the set voltage signal exceeds the working voltage range of the energy storage motor 20, the toggle rod 21 is electrically connected with the first contact 22, so that the voltage-reducing and current-limiting component 3 is electrically connected with the energy storage motor 20, and the main power supply 11 or the standby power supply 12 can regulate the input voltage of the energy storage motor 20 through the voltage-reducing and current-limiting component 3 so as to meet the working voltage requirement of the energy storage motor 20, and finally the energy storage motor 20 is protected from being damaged.
In summary, the switching assembly 10 according to the present disclosure can meet the requirements of different voltages only by matching with the same energy storage motor 20, and no additional alternative model of the energy storage motor 20 is needed, thereby reducing the difficulty of controlling the products and production, and reducing the design cost and production cost.
The buck current limiting member 3 according to embodiments of the present disclosure may be various types of buck current limiting members 3 currently known or available in the future, as embodiments of the present disclosure are not limited in this regard. For example, in some embodiments, buck current limiting component 3 may be a resistor. In other embodiments, buck current limiting component 3 may be a buck chip.
In some embodiments, the set voltage signal includes four, e.g., 380V, 400V, 415V, and 440V; the operating voltage range of the energy storage motor 20 includes 380-415V. It can be seen that in case the set voltage signal comprises 380V, 400V and 415V, the main power supply 11 or the backup power supply 12 directly supplies power to the energy storage motor 20. In the case where the set voltage signal includes 440V, the energy storage motor 20 needs to be protected from being damaged.
It should be noted that the numbers, values, numbers, etc. mentioned above and as may be referred to elsewhere in the disclosure are exemplary and are not intended to limit the scope of the disclosure in any way. Any other suitable numbers, values, numbers are possible. For example, the set voltage signal and the operating voltage of the energy storage motor 20 may include more or less values depending on the particular application scenario and requirements.
With continued reference to fig. 1, in some embodiments, the input member 6 is electrically connected to an input of the micro control unit 5. A voltage value may be set on the input part 6, and the input part 6 transmits a set voltage signal to the micro control unit 5. The micro control unit 5 can control the toggle rod 21 to be electrically connected with the first contact 22 or control the toggle rod 21 to be electrically connected with the second contact 23 according to the comparison result of the set voltage signal and the working voltage of the energy storage motor 20.
The input member 6 according to the embodiment of the present disclosure may be various types of input members 6 currently known or available in the future, to which the embodiment of the present disclosure is not limited. For example, in some embodiments, the input component 6 may be an LCD screen. In other embodiments, the input member 6 may be a rotary switch type input member.
It should be noted that, in the case where the input unit 6 is an LCD screen, the LCD screen may include a touch screen, and a specific voltage value may be set by clicking the touch screen; or the LCD screen is a non-touch screen, the screen is only used for displaying the input numerical value, and the specific voltage numerical value can be set by pressing a key. In the case where the input member 6 is a rotary switch type input member, the voltage value can be set by turning the knob to a specific value.
