Technical Field

[0001] This utility model belongs to the field of power supply equipment technology, specifically referring to a power supply device for a capacitive strip uniformity test and analysis instrument. Background Technology

[0002] Capacitive yarn evenness testers are commonly used in the textile industry to accurately detect yarn evenness. A stable power supply is essential for accurate data processing. Currently, many power supplies for these analyzers suffer from poor power stability. Fluctuations in the mains voltage can lead to unstable output voltage, affecting the analyzer's accuracy. Furthermore, the power supplies lack effective overload protection; prolonged use can result in circuit overload damage. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model proposes a power supply device for a capacitive strip uniformity test and analyzer, which effectively solves the problems of poor power supply stability and lack of overload protection in the power supply device of the capacitive strip uniformity test and analyzer.

[0004] The technical solution adopted by this utility model is as follows: The power supply device of the capacitive strip uniformity test analyzer proposed by this utility model includes a power supply shell, a circuit board is provided inside the power supply shell, a power interface and an output interface are fixedly installed on the side of the power supply shell, and a power supply module, a voltage regulator module and an overload protection module are installed on the circuit board, with the voltage regulator module located between the power supply module and the overload protection module.

[0005] Preferably, the power supply module includes a transformer mounted on a circuit board and electrically connected to a power interface, a rectifier circuit mounted on the circuit board and electrically connected to the transformer, and a filter mounted on the circuit board and electrically connected to the rectifier circuit.

[0006] To achieve better voltage regulation, the voltage regulation module includes a DC voltage regulator chip mounted on a circuit board. An input capacitor is mounted on the circuit board and electrically connected to the DC voltage regulator chip. An output capacitor is mounted on the circuit board and electrically connected to the DC voltage regulator chip. The output capacitor is electrically connected to an output interface. The DC voltage regulator chip is electrically connected to a filter.

[0007] To achieve overload protection more quickly, the overload protection module includes a relay mounted on a circuit board, and an overload detection chip is mounted on the circuit board and electrically connected to the relay.

[0008] To achieve the protection effect, the relay is connected in series between the filter and the input capacitor.

[0009] Furthermore, the overload detection chip is electrically connected to the filter. When an overload is detected in the circuit, the relay can quickly cut off the power supply circuit to prevent circuit damage.

[0010] The beneficial effects of this utility model using the above structure are as follows: The power supply device of the capacitive strip uniformity test analyzer proposed in this solution ensures the stability of the power supply output voltage through the voltage stabilization module, avoiding the impact of power grid fluctuations on the analyzer's detection accuracy; and the overload protection module realizes rapid power-off protection when the circuit is overloaded, preventing damage to the power supply device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the power supply device of the capacitive strip uniformity test analyzer proposed in this utility model includes a power supply housing 1, a circuit board 2 is provided inside the power supply housing 1, a power interface 3 and an output interface 4 are fixedly installed on the side of the power supply housing 1, and a power supply module 5, a voltage regulator module 6 and an overload protection module 7 are installed on the circuit board 2, with the voltage regulator module 6 located between the power supply module 5 and the overload protection module 7.

[0019] like Figure 3 and Figure 4 As shown, the power supply module 5 includes a transformer 8 mounted on the circuit board 2 and electrically connected to the power interface 3, a rectifier circuit 9 mounted on the circuit board 2 and electrically connected to the transformer 8, and a filter 10 mounted on the circuit board 2 and electrically connected to the rectifier circuit 9.

[0020] like Figure 3 and Figure 4 As shown, the voltage regulator module 6 includes a DC voltage regulator chip 11 mounted on a circuit board 2. An input capacitor 12 is mounted on the circuit board 2 and electrically connected to the DC voltage regulator chip 11. An output capacitor 13 is mounted on the circuit board 2 and electrically connected to the DC voltage regulator chip 11. The output capacitor 13 is electrically connected to the output interface 4. The DC voltage regulator chip 11 is electrically connected to the filter 10.

[0021] like Figure 3 and Figure 4 As shown, the overload protection module 7 includes a relay 14 mounted on the circuit board 2. The relay 14 is connected in series between the filter 10 and the input capacitor 12. An overload detection chip 15 is mounted on the circuit board 2 and electrically connected to the relay 14. The overload detection chip 15 is electrically connected to the filter 10. When an overload is detected in the circuit, the relay 14 can quickly cut off the power supply circuit to avoid circuit damage.

[0022] In practical use, the user first connects the output line on the power supply output interface 4 to the body of the capacitive strip uniformity test analyzer. Then, the user uses the power cord on the power interface 3 to connect the external AC power supply to the transformer 8 of the power supply module 5. After being transformed by the transformer 8, the AC power supply is rectified by the rectifier circuit 9 and filtered by the filter 10, and then converted into a stable preliminary DC power supply. A portion of the preliminary DC power supply is sent to the voltage regulator module 6, where it is regulated by the DC-DC voltage regulator chip 11, and filtered by the input capacitor 12 and the output capacitor 13. Finally, it provides a stable DC power supply to the analyzer through the output interface 4. At the same time, the relay 14 monitors the current in the power supply circuit in real time. When an overload is detected, the overload detection chip 15 cuts off the circuit between the power supply module 5 and the voltage regulator module 6 to achieve overload protection. The above is the entire process of using the power supply device of the capacitive strip uniformity test analyzer.
