Description

Technical Field

[0001] The invention belongs to the technical field of power system automation, and relates to a debugging wiring device, in particular to a distribution automation terminal debugging wiring device, which is specially suitable for the debugging work of distribution terminals in the automation transformation of distribution networks. Background Art

[0002] With the rapid development of social economy and the growth of electricity demand, the traditional distribution system can no longer meet the needs of modern society. Distribution automation can significantly improve power supply reliability by integrating advanced information communication technology and control technology to achieve real-time monitoring, intelligent analysis and automatic control of the distribution network. Through the automatic isolation of faults and the rapid restoration of power supply, the power outage time can be reduced, the scope of power outage can be narrowed, and stable power supply for users can be ensured. Secondly, the transformation helps to improve the quality of power. Through the flexible adjustment of the distribution network, the voltage quality can be improved and the power loss can be reduced. In addition, distribution automation provides basic data support for distribution network planning and technical transformation, which is conducive to the long-term healthy development of the power grid.

[0003] The development of distribution automation technology can be traced back to the 1990s, when advanced distribution automation systems began to appear at home and abroad. These systems have been applied in traditional distribution networks and have achieved remarkable results. With the continuous advancement of information technology, such as big data, cloud computing, and the Internet of Things, distribution automation technology has developed rapidly, and intelligent equipment and systems have become the core of power grid distribution automation technology. These technologies can not only realize remote monitoring and control of power equipment, but also realize real-time monitoring and analysis of the operating status of the power grid, thereby ensuring the safe and reliable operation of the power grid.

[0004] The automation transformation of my country's distribution network is accelerating, and more and more distribution automation terminals are being installed on distribution station buildings, pole switches, distribution transformers and other equipment. The commissioning and maintenance of distribution automation terminals are key tasks to ensure the stable operation of the distribution network. With the rapid development of the distribution network and the improvement of the level of intelligence, the challenges faced by staff are also increasing. At present, when staff are commissioning and maintaining distribution automation terminals, there are many terminals that need to be handled, and there may be differences in terminal configurations and debugging software from different manufacturers, which increases the complexity of the work. In order to ensure the normal operation of the distribution terminal, its "three remote" functions must be fully verified before the equipment is powered on and during its entire life cycle.

[0005] When testing telesignaling and remote control signals, the actual signals required for the running primary switchgear cannot be generated by direct operation, but the corresponding segments must be short-circuited and disconnected on the secondary terminal strip to generate analog signals for testing. At this time, the conventional practice is to use short-circuit wires, which are generally temporarily cut 2.5-4mm2 plastic copper wires. The staff manually plugs the terminal strips for operation. Although it can meet the basic needs of the work, the plug-in is not firm, the operation is not convenient, and it is easy to cause misoperation. In addition, when multi-point signal linkage is required, two people must cooperate to complete the test, which has low work efficiency and cannot meet the increasing transmission workload.

[0006] Therefore, how to find a method that is firmly plugged and easy to operate is a technical difficulty that needs to be solved urgently by those skilled in the art.

[0007] After searching, no public documents of the prior art that are identical or similar to the present invention were found. Summary of the invention

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a distribution automation terminal debugging wiring device which has a reasonable design, firm plugging and simple operation.

[0009] The present invention solves the practical problem by adopting the following technical solutions:

[0010] A distribution automation terminal debugging wiring device comprises a shell, in which a plurality of reels are arranged side by side, each reel is wound with a debugging line corresponding to a debugging signal by means of a tape measure structure, one end of the debugging line is made into a debugging plug for inserting into an automation terminal terminal block during transmission, the other end of the debugging line is welded to a connection contact in a debugging switching switch group and is led out by the debugging switching switch group, the debugging switching switch group is used to form a switch circuit, switch a debugging signal, indicate a signal state and lead out the debugging line.

[0011] Moreover, the debugging switching switch group is installed above the shell, and the debugging switching switch group includes a printed circuit, multiple micro switches, multiple connection indicator lights, multiple debugging signal connection terminals and a common end; the multiple debugging signal connection terminals include: switch position, no energy storage, remote / local, ground position, isolation position and common end; one end of each debugging signal connection terminal is connected to the corresponding debugging signal connection contact through the micro switch and the indicator light, and the other end is connected to the corresponding debugging line, the micro switch is used to open and close the corresponding signal circuit; the indicator light is used to indicate the on and off state of the circuit.

[0012] Moreover, when the micro switch is turned to the ON side, the debugging line of the corresponding debugging signal is connected to the common end, and a high-level signal "1" is input; when the micro switch is turned to the OFF side, the debugging line of the corresponding debugging signal is disconnected from the common end; when a low-level signal "0" is input, multiple debugging lines corresponding to debugging signals can be connected or disconnected from the common end at the same time to form a combined signal, and when the corresponding signal is connected, the remote signal input board voltage will be added to both ends of the connection indicator light to make the connection indicator light up, clearly showing the signal connection status.

[0013] Moreover, each reel is a spring self-resetting rotating wire-retrieving shaft, and the debugging line can be reset by the spring.

[0014] Furthermore, a wire clamp is arranged on the housing to limit the position of the debugging wire when the debugging plug is inserted into the automation terminal terminal block.

[0015] Advantages and beneficial effects of the present invention:

This design not only saves debugging time, but also reduces the labor intensity of on-site personnel, making the debugging process smoother.

[0017] 2. Aiming at the shortcomings of existing distribution automation terminal debugging tools in terms of cumbersome operation, low efficiency and multi-person cooperation, the present invention proposes a portable multifunctional distribution automation terminal debugging wiring device, which achieves significant technical improvements and ease of use through integrated design.

[0024] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0025] A distribution automation terminal debugging wiring device, such as Figure 1 ,and Figure 2As shown, it includes a shell, in which a plurality of reels are arranged side by side, each reel is wound with a debugging line corresponding to a debugging signal by a tape measure structure, one end of the debugging line is made into a debugging plug, which is used to be inserted into the automation terminal terminal block during transmission, and the other end of the debugging line is welded to the connection contact in the debugging switching switch group and is led out by the debugging switching switch group, and the debugging switching switch group is used to form a switch circuit, switch the debugging signal, indicate the signal state and lead out the debugging line;

[0026] In this embodiment, the debugging switching switch group is installed above the shell, and the debugging switching switch group includes a printed circuit, multiple micro switches, multiple connection indicator lights, multiple debugging signal connection terminals and a common end; the multiple debugging signal connection terminals include: switch position, no energy storage, remote / local, ground position, isolation position and common end; one end of each debugging signal connection terminal is connected to the corresponding debugging signal connection contact through the micro switch and the indicator light, and the other end is connected to the corresponding debugging line, the micro switch is used to open and close the corresponding signal loop; the indicator light is used to indicate the on and off state of the loop.

[0027] In this embodiment, when the micro switch is turned to the ON side, the debugging line of the corresponding debugging signal is connected to the common end, and a high level signal "1" is input; when the micro switch is turned to the OFF side, the debugging line of the corresponding debugging signal is disconnected from the common end; when a low level signal "0" is input, multiple debugging lines corresponding to debugging signals can be connected or disconnected with the common end at the same time to form a combined signal, and when the corresponding signal is connected, the remote signal input board voltage will be added to both ends of the connection indicator light to make the connection indicator light up, clearly showing the signal connection status.

[0028] In this embodiment, each reel is a spring self-resetting rotating wire-retrieving shaft, and the debugging line can be reset by the spring.

[0029] In this embodiment, a wire holder is provided on the housing to limit the debugging wire when the debugging plug is inserted into the terminal block of the automation terminal.

[0030] The working principle of the present invention is:

[0031] The debugging wiring device of the present invention adopts a mechanical structure similar to a tape measure and is loaded into a reel housing, wound on a rotating shaft with a spring reset function, one end of which is made into a debugging plug, which is convenient for inserting into the terminal row of the automation terminal during transmission, and the other end is welded on the connection contacts of the debugging switching switch group. The debugging switching switch group is a key module of the wiring device, which is composed of a printed circuit, a micro switch, a connection indicator light and a connection contact. One end of the connection terminal of each debugging signal is connected to the corresponding debugging signal connection contact through the micro switch and the indicator light, and the other end is connected to the corresponding debugging line. When the micro switch is turned to the ON side, the debugging line of the corresponding debugging signal is connected to the common end, and a high level signal "1" is input on the terminal. When the switch dial is turned to the OFF side, the debugging line of the corresponding debugging signal is disconnected from the common end, and a low level signal "0" is input on the terminal. The debugging lines of multiple corresponding debugging signals can be connected or disconnected with the common end at the same time to form a combined signal, and when the corresponding signal is connected, the voltage of the remote signal input board will be added to the two ends of the connection indicator light to make the connection indicator light up, clearly showing the signal connection situation. For example, to simulate the combined signal of "switch closed, isolation closed, no energy storage, local operation, grounding switch open", just set the micro switch to "ON, ON, OFF, OFF, ON" according to the number. When using on site, pull out the debugging line, clamp it with the wire clamp, and then insert the debugging plug into the corresponding position of the DTU cabinet terminal block. Switch the switch group as needed. After debugging, turn all the switch groups to OFF, pull out the debugging plug, open the wire clamp, and the debugging line is put into the shaft under the action of the reset spring.

[0032] The design of the debugging wiring device adopts the concept of modularization and integration, which significantly improves the debugging efficiency and accuracy. Through the combination innovation of the mechanical structure, the winding and releasing of the debugging line realizes fast operation, reducing the complexity and time consumption in the traditional wiring method. The spring reset function ensures the neat storage of the debugging line, avoids the chaos on site, and improves the safety of the working environment. The design of the core component wiring reflects a high degree of flexibility and user-friendliness. The integrated design of the debugging switching switch group makes the switching and indication of multiple signals intuitive and easy to understand, reducing the possibility of operating errors. The combination of micro switches and indicator lights not only provides clear signal status feedback, but also realizes the connection and disconnection of signals through simple toggle operations, simplifying the debugging process. In terms of visualization, the introduction of the remote signal input board voltage realizes real-time monitoring of the signal connection status, and the intuitive display of the on and off of the connection indicator light improves the intelligent level of debugging. This design not only improves the reliability of debugging, but also provides a convenient operation interface for on-site operators.

[0033] In general, the innovation of the present invention lies in its unique mechanical structure design, modular core component wiring and visual status monitoring, which significantly improve the efficiency, safety and intelligence level of distribution automation commissioning. Through these designs, the debugging wiring device can better adapt to the complex and changeable field environment and provide strong support for the rapid deployment and maintenance of automation terminals.

[0034] The preparation process of the present invention is:

[0035] According to the design drawings, test products are made, and high-strength engineering plastics or metal alloys are selected as the shell material to ensure that the wiring device has sufficient mechanical strength and corrosion resistance in various environments. Aluminum alloy is a commonly used metal alloy material. It not only has good mechanical properties, but also has the characteristics of light weight and corrosion resistance, and is suitable for various industrial environments. At the same time, the shell design should include reasonable anti-slip textures to improve the operator's grip stability during use. The anti-slip texture can be formed on the shell surface through die-casting or injection molding processes to increase friction and prevent slipping during operation.

[0036] The wiring device should be designed with debugging line storage intervals corresponding to each signal. These intervals need to be precisely designed according to the size and shape of the debugging line to ensure that the debugging line can be kept neat during use and storage to avoid crossing and damage.

[0037] The short-circuit wire should be specially designed and processed to ensure it has good flexibility, conductivity and durability. The length and type of the short-circuit wire should be customized according to actual needs to adapt to different test scenarios.

[0038] The manufactured samples are tested for actual application at the transmission site, and necessary adjustments and improvements are made according to the usage. This step is crucial to ensure that the final product can meet the actual needs of the on-site staff.

[0039] According to the test and improvement results, the final products are produced. These products will be configured for use by distribution automation staff to improve the efficiency and safety of commissioning work.

[0040] During the entire manufacturing process, the design requirements and industrial standards should be strictly followed to ensure that each sample and final product can meet the expected performance indicators. In this way, the reliability and practicality of the invented debugging wiring device in actual application can be ensured.

[0041] The innovation of the present invention lies in:

[0042] First of all, the portable multifunctional distribution automation terminal debugging wiring device integrates the short-circuit combination into one, which is easy to use and greatly simplifies the tedious steps of frequently replacing and adjusting the short-circuit during the debugging process. In the traditional debugging method, the staff needs to carry a large number of short-circuit wires and connect them one by one as needed, which is not only time-consuming and labor-intensive, but also prone to errors. The invention of this wiring device completely solves this problem, making the debugging process simpler and more intuitive.

[0043] Secondly, the design of this debugging wiring device also takes into account the convenience of single-person operation. Traditional debugging work often requires the collaboration of multiple people to complete multi-point signal combination testing. However, this wiring device, through its sophisticated structural design, allows only one person to easily complete multi-point signal combination testing, greatly saving human resources and improving work efficiency.

[0044] Finally, the debugging and wiring device can be easily retracted after use, reducing the need for storage space.

[0045] The application of the portable wiring device of the present invention will effectively promote the process of distribution network automation transformation and bring important changes to the debugging and maintenance of distribution automation terminals. It combines portability, ease of operation and high accuracy, which not only improves work efficiency but also reduces the error rate of operation. It is an important tool for realizing efficient operation and maintenance of distribution network automation terminals. With the continuous development of distribution automation technology, the application prospects of this device will be broader, providing strong support for promoting the construction and operation and maintenance of smart grids.

[0046] It should be emphasized that the embodiments of the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation modes. Any other implementation modes derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
