Description

Technical Field

[0001] This application relates to the field of power system technology, and in particular to a secondary cable pairing device. Background Technology

[0002] In power systems, substations play a crucial role, responsible for the conversion and distribution of electrical energy. Secondary cables, as a key component of substations, are primarily responsible for control, signal transmission, and feedback functions. The quality of these cable installations directly affects the safe and stable operation of the substation. During the construction and commissioning of a substation, verifying the conductors in the secondary circuits—a process known as "wire matching"—is an indispensable step. This process ensures correct circuit connections, which is essential for guaranteeing the safe operation of the substation.

[0003] Traditional cable matching methods rely on manual operation, typically requiring two workers to use multimeters and jumpers to verify the wire cores at both ends of the cable. This method is inefficient, especially when dealing with thousands of secondary cables in a substation; it is not only time-consuming and labor-intensive but also prone to errors. Furthermore, due to the limitations of manual operation, this method cannot simultaneously test and verify multiple circuits, nor can it meet the needs of long-distance signal transmission, particularly in environments requiring electromagnetic interference resistance. Therefore, there is an urgent need to develop a miniature device for simultaneous multi-circuit matching of secondary cables suitable for substations.

It contains eight D-type latches, each with an independent latch enable input. Pins 1-8 are the latch outputs (Q0-Q7), which output stable data until the next latch enable signal arrives. Pins 9-16 are the latch inputs (D0-D7), used to receive the data to be latched. Pins 10 and 11: GND (Ground) pins, used to provide the circuit's reference ground potential. Pins 20 and 19: VCC (Power) pins, used to provide the chip's operating voltage. Pin 18: OE (Output Enable) pin; when this pin is low, the latch output is enabled; when high, the output is disabled. The power strip is a multi-pin connector for connecting external devices or expansion circuitry. It provides eight connection points, corresponding to the eight outputs of the 74HC573N. The outputs (Q0-Q7) of the 74HC573N connect to the corresponding pins of a connector, allowing external devices or circuits to read latched data through the connector. The inputs (D0-D7) of the 74HC573N can be connected to other circuitry to receive the data to be latched. The OE pin of the 74HC573N needs to be connected to a control signal to control the timing of data latching. The VCC and GND pins of the 74HC573N need to be connected to power and ground for power supply and reference potentials, respectively.

[0048] This embodiment improves signal storage and processing capabilities through the use of latch units, enabling the wiring module to handle complex signal transmission tasks.

[0049] Furthermore, in some embodiments, the secondary cable pairing device further includes a resistor array module, which includes a resistor array consisting of eight 10kΩ resistors. The first pin of the resistor array is the common connection terminal of all resistors, and the common connection terminal is connected to the power supply voltage. The second, third, fourth, fifth, sixth, seventh, eighth and ninth pins of the resistor array are respectively connected to the main control module.

[0050] Specifically, the secondary cable pairing device provided in this embodiment also includes a resistor array module, which comprises a resistor array consisting of eight 10kΩ resistors. A resistor array is an electronic component that integrates multiple resistors, commonly used for voltage division, current limiting, or providing connection points for multiple resistors with the same resistance value. The first pin of the resistor array is the common connection terminal for all resistors; this terminal is connected to the power supply voltage to provide power to the resistor array. The second to ninth pins of the resistor array are respectively connected to the main control module to implement different resistor connections and signal distribution. By using an integrated resistor array instead of multiple individual resistors, space can be saved, the number of components on the circuit board can be reduced, and circuit design and wiring can be simplified. Using resistor arrays with the same resistance value ensures resistance matching in various parts of the circuit, improving circuit consistency and reliability. The multiple pins provided by the resistor array can be flexibly connected to the main control module, providing more configuration options for circuit design.

[0051] In specific embodiments, such as Figure 2 As shown, the resistor array module is a 10K resistor array containing eight 10kΩ resistors, each corresponding to one I / O port of the microcontroller. Pins 1-8 are the resistor connection terminals, each connected to a pin of the microcontroller's P0 port. Pin 9 is the common connection terminal, connecting all resistors to VCC. The microcontroller's P0 port pins P0.0 through P0.7 are I / O pins, connected to VCC via 10K resistors. VCC is the microcontroller's positive power supply, providing voltage to the pull-up resistors. Each P0 port pin (P0.0 through P0.7) is connected to VCC via a 10K resistor. This configuration ensures that the I / O ports remain high when not driven, thanks to the pull-up resistors. This pull-up configuration is particularly useful for microcontroller input ports because it prevents the ports from being in an indeterminate state without explicit drive, a state known as "floating" in digital circuit design. Pull-up resistors help stabilize the input signals of a microcontroller, preventing malfunctions caused by external interference or unconnected inputs. They ensure that I / O ports are in a known high-level state when no external signal is driving them. Using resistor arrays simplifies circuit design, reduces the number of required resistors, and makes wiring cleaner.

[0052] The use of integrated resistor arrays in this embodiment reduces the number of components on the circuit board, simplifies circuit design and wiring, and lowers manufacturing costs. Because the resistor array integrates multiple resistors, the soldering work for individual resistors can be reduced during assembly, improving production efficiency. Uniform resistance values ​​help ensure resistance matching across different parts of the circuit, reducing circuit instability caused by inconsistent resistance values. The multiple pins provided by the resistor array can be flexibly connected to the main control module, offering more options for signal distribution and improving circuit flexibility. The use of integrated resistor arrays reduces the number of connection points on the circuit board, thereby reducing potential failure points and improving circuit reliability.
