Description

Technical Field

[0001] The present invention belongs to the field of signal triggering, and in particular relates to a simple signal triggering device and a detection method for a transformer substation. Background Art

[0002] With the development of my country's economy, power facilities are more widely used in various fields such as industry and agriculture in my country, and the dependence of various fields on them has increased. People have put forward higher requirements for the stable and continuous operation of the power system. The technical level of my country's substation equipment maintenance technology varies greatly from region to region, which has formed a major contradiction and conflict with local economic development to a certain extent. As we all know, the power system is an important guarantee for modern production and life. It mainly serves my country's industrialization, agriculturalization and people's life needs. Since my country's substation equipment maintenance technology has not been fully innovated and transformed in terms of system methods and systems for a long time, my country's substation equipment maintenance technology still has certain defects. Therefore, for my country, with the needs of economic development, it is of great historical significance to improve substation maintenance technology and ensure the smooth operation of the power system.

[0003] Problems that arise during substation maintenance work:

[0004] 1. The professional and technical level of maintenance staff is relatively low

[0005] Substation maintenance work is influenced by factors such as the specific conditions of the equipment being repaired, the surrounding environment, and the professional and technical expertise of maintenance personnel. Therefore, during maintenance work, it is crucial to understand the specific conditions of the substation on-site maintenance in advance to minimize the adverse effects of unexpected situations during maintenance, reduce safety risks during maintenance work, and safeguard the lives of maintenance personnel. Furthermore, the overall professional skills of most substation maintenance personnel are relatively low. Most lack proper safety awareness, fail to properly understand the importance of maintenance work, and fail to strictly follow standard procedures. This significantly increases the safety risks of substation maintenance work and the likelihood of substation failures. Furthermore, some company leaders fail to prioritize improving the professional skills of maintenance personnel and fail to organize timely skills training and development. As a result, some maintenance personnel lack a thorough understanding of the structure and components of substation equipment and devices, which in turn leads to maintenance personnel performing work that does not comply with relevant regulations. This significantly impacts the overall quality and efficiency of substation maintenance work.

[0006] 2. Non-standard maintenance operations increase the safety risks of maintenance work

[0007] The current maintenance standard system for substations in China is relatively complex, resulting in a lack of fixed standards for maintenance procedures for maintenance personnel. This has, to a large extent, led to many problems in actual maintenance work. At the same time, some maintenance personnel are unclear about the relevant work processes and do not have a good grasp of the specific operations of related maintenance work. These have greatly reduced the quality and efficiency of substation maintenance work, increased the risk of power safety accidents, and hindered the daily operation of the power system. From the perspective of the long-term development of the domestic power system, the management model of the power system generally uses the work ticket management system as a management standard. However, in the actual development process, this system cannot effectively standardize each step of the maintenance work, making it impossible to carry out maintenance work comprehensively and effectively, resulting in the efficiency and quality of maintenance work falling short of ideal expectations. The relevant regulations and requirements are too one-sided and there is no unified standard.

[0008] 3. Related equipment and devices lack certain safety features

[0009] Some substation equipment has low safety performance, and frequent maintenance operations significantly increase the chances of equipment failure. Furthermore, some substations have long service lives and poor overall performance, often experiencing equipment operating beyond its intended lifespan and aging parts. This significantly reduces the safety performance of substation equipment, significantly increasing the workload for maintenance personnel and increasing safety risks.

[0010] During the secondary maintenance pre-test work of the substation, the virtual telesignaling method is often used to check the correctness of the secondary circuit and the signal configuration of the monitoring system database. The current method for substation operations to complete this work is for the staff to trigger the telesignaling signal one by one with the help of short-circuit wires. This method lacks safety monitoring guarantees, and the staff's work is obviously arbitrary. In addition, the telesignaling, telemetering, and remote control circuits coexist in the secondary screen, and there are safety hazards such as wrong triggering, wrong short circuiting, and personal electric shock during work. The present invention mainly designs a simple signal triggering device with a fixed working range to facilitate monitoring and execution, ensure the correct operation of the telesignaling signal, and reduce the chance of electric shock to personnel.

[0011] Chinese patent CN103217657A discloses a detection method for a substation signal trigger device measurement and control device. The operation process in this application is relatively complicated. Chinese patent CN206353724U discloses a device for remote signal reset of substation secondary equipment. Although the device disclosed in this application does not require maintenance personnel to go to the site specifically, thereby improving the work efficiency of maintenance personnel, the operation process is complicated and the professional and technical requirements of maintenance personnel are relatively high. Summary of the Invention

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0049] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings.

[0055] (2) The remote signal point number of the signal generating device corresponds to the input point number of the device;

[0056] (3) Check the signal generation status at the monitoring system or measurement and control device panel in the main control room;

[0057] (4) The signal trigger device can realize two modes of remote signal transmission: automatic point-to-point and one-by-one point-to-point, which can be realized by selecting the transmission mode on the input module;

[0058] (5) After selecting the input operation command in the input module, the display will show the remote signal point number under the current command;

[0059] (6) After receiving the operation instruction, the single chip microcomputer sends out a level to close the auxiliary contact corresponding to the output module, thereby turning on the open-in circuit required by the operation instruction and triggering the open-in signal.

[0060] (7) An indicator light is provided on the power supply side of the signal triggering device. After the input signal is triggered successfully, the indicator light will light up to indicate that the signal is triggered successfully.

[0061] (8) If the indicator light is on and there is no position change information in the measurement and control device or monitoring system, it is necessary to perform fault analysis on the device and check the configuration of the monitoring system, replace parts, return to the factory for repair, or reconfigure the monitoring system. After maintenance, repeat steps 5-7 until the test results are normal.

[0062] like Figure 1-4 As shown, a simple signal triggering device for a substation includes a power supply side 1 and a signal triggering side 2. The power supply side 1 and the signal triggering side 2 are connected by a push-button shell. The power supply side 1 is provided with a switch button 8, and the signal triggering side 2 is provided with a signal triggering button 9. The middle positions of the power supply side 1 and the signal triggering side 2 are fixedly connected with a copper bus 7, and the copper bus 7 is connected to a movable rod 4. The movable rod 4 is provided with a movable contact 5. The copper bus 7 of the power supply side 1 and the signal triggering side 2 are both connected with a wire 6. The copper bus 7 of the power supply side 1 and the signal triggering side 2 are connected by a wire 6. An insulating bayonet 3 is provided on the back of the cabinet body 2, and the insulating bayonet 3 is adapted to the terminal block 11 on the secondary panel cabinet. The number of switch buttons on the power supply side 1 is 3, and the number of signal triggering buttons on the signal triggering side 2 is 48.

[0063] The use process of the present invention: when we need to send a signal, first press the power button 8, the spring on the movable contact 5 inside the power supply 1 is squeezed, so that the spring contacts the metal contact of the terminal row on the secondary screen, and the power of the terminal row is turned on, and then press the corresponding signal trigger button on the signal trigger side 2, the spring on the movable contact 5 inside the signal trigger side 2 is squeezed, so that the spring contacts the metal contact of the segment row on the secondary screen, the power side 1 and the signal trigger side 2 are fixedly connected to the copper bus 7, the power side 1 and the signal trigger side 2 copper bus 7 are connected by a wire 6 to form a closed loop, and the corresponding signal is sent out. The copper bus is easier to fix than the wire, simple to operate, and easy to replace. The copper bus on the power side 1 and the signal trigger side 2 are connected by a wire, the length of the wire can be adjusted, and the distance between the power and signal on the segment row is not fixed. The length of the wire can be adjusted according to the actual situation to better meet the needs of various occasions.

[0064] This device secures the operating range, facilitates effective monitoring, ensures correct telesignaling, and reduces the risk of electric shock. The power supply side 1 and the signal trigger side 2 are connected by a flexible conductor 6 to accommodate field work environments. The device is secured to the secondary cabinet terminal block using insulating clips 3 and can accommodate terminal blocks of varying sizes. A single-chip microcontroller (MCU) is integrated into the device, allowing for both automatic and point-to-point alignment of analog signal transmission, reducing workload.

[0065] Example 2

[0066] This embodiment differs from embodiment 1 in that:

[0067] like Figure 1-4 As shown, the copper bus 7 is connected to a movable rod 4, and a movable contact 5 is provided on the movable rod 4. A metal sheet 13 is fixedly connected to the movable contact 5, and a spring 12 is fixedly connected to the metal sheet 13. In a normal state, the spring 12 is in a pop-up state and does not contact the metal connection point on the terminal block. When the button is pressed, the spring 12 is squeezed and contacts the metal connection point on the terminal block to form a closed loop, which can send out the signal. The device is simple to operate and has high sensitivity.

[0068] Example 3

[0069] This embodiment differs from embodiment 1 in that:

[0070] like Figure 1-4As shown, an indicator light 10 is connected to the power supply side 1. When the trigger signal button is pressed, the indicator light 10 lights up, indicating that the signal is triggered successfully. If the indicator light 10 is not on, the signal trigger fails. This is convenient for observation, improves work efficiency, fixes the working scope, facilitates monitoring and execution, ensures the correct operation of the remote signal, and reduces the chance of electric shock.

[0099] This embodiment adds an automatic alignment mode, enabling automatic or step-by-step alignment by inputting operational commands, while retaining the manual mechanical alignment mode. In automatic alignment mode, the signal and power contacts are brought into direct contact with the terminal block. Signal triggering is determined by the microcontroller, output module, and input module. Input commands close the corresponding auxiliary contacts on the output module, thereby energizing the input circuit and triggering the input signal.

[0100] In this embodiment, when the automatic mode fails (when the single chip computer, input or output module fails), the manual mechanical mode is selected, which is convenient to use, easy to operate, and has better safety performance.

[0101] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
