Description

Technical Field

[0001] The present invention relates to the technical field of substation equipment maintenance, and in particular to a substation secondary intelligent deployment control device. Background Art

[0002] Substation equipment maintenance management is the foundation and core work of power grid companies. In recent years, more and more emphasis has been placed on clarifying safety management responsibilities in power grids, requiring operation and maintenance personnel to "control the boundaries of operating equipment and the safety measures of maintenance equipment" according to on-site operations, and strictly control all kinds of unsafe behaviors and unsafe factors.

[0003] In recent years, due to rapid economic development and technological breakthroughs, power equipment has also been updated and iterated. The development of new technologies has also increased the unsafe factors of power equipment, especially in the maintenance process. Personal accidents caused by misjudgment of breaking through the maintenance work surface or misoperation of secondary equipment have shown a significantly high incidence.

[0004] Nowadays, Zhongwei District vigorously develops and builds cloud bases, industrial parks, and new energy stations to achieve reliable power supply for users with multiple power sources and increase the coverage of power grid. In the past five years, 15 new substations have been built, and several new 330kV substations have been taken over. The number of transformers, indoor closed switchgear, outdoor open capacitors, mutual inductors and other equipment in the station has also increased significantly, resulting in an increase in the maintenance workload of the equipment year by year.

[0005] At present, there is still a lack of effective technical means to cooperate with management and organizational measures to prevent safety risks caused by human factors in the deployment link. The current deployment work mainly relies on tools such as red curtains, magnetic warning tapes, and operating equipment identification plates for deployment. The existing deployment tools are fixed in size and cannot be deployed in a targeted manner according to the size of the equipment. They are also easy to fall. At the same time, in the existing deployment process, it is usually necessary to clarify the deployment scope according to the information on the work ticket, select the deployment tools of appropriate size, deploy within the working scope, and rearrange when the deployment measures fall. These links waste a lot of time, resulting in increased deployment time and low efficiency.

[0006] With the rapid development of intelligent technology, intelligent control is introduced into more and more work. Compared with manual control, it has high control accuracy and fast calculation speed, and can be effectively applied to daily life and work. In order to solve the current problems encountered in the maintenance and management of substation equipment, it is necessary to apply intelligent control to the maintenance and management of substation equipment, improve the maintenance efficiency, ensure the accuracy of maintenance, and ensure the reliable and stable operation of the power grid. Summary of the invention

[0007] In order to overcome the above problems, the purpose of the present invention is to provide a secondary intelligent deployment and control device for a substation, which isolates the equipment of the substation by using the air-open lock, operating handle lock, protective pressure plate lock and padlock provided by the deployment tools and the base installation module. The isolation means is reliable and convenient, and effectively eliminates the possibility of misoperation accidents by on-site staff. The correct maintenance tasks are generated by the information collection module and the maintenance interval deployment surface generation module, and the accuracy of the maintenance tasks is further ensured by the maintenance interval five-protection verification module. The opening and closing of the lock is established through the computer key communication module, and the maintenance work is transformed from the original human-controlled management mode relying on the system and human active control to a technical-controlled management mode supervised and restricted by a third-party device, which effectively improves work efficiency and ensures work quality.

[0056] like Figures 1 to 6 As shown, it shows a specific embodiment of the present invention:

[0057] Embodiment 1

[0058] A secondary intelligent defense control device for a substation includes an information collection module, a maintenance interval defense surface generation module, a maintenance interval five-defense verification module, a computer key communication module, a defense tool and a base installation module.

[0059] The information collection module adopts five-defense information collection to establish the connection between the deployment computer and the primary and secondary equipment on site.

[0060] The maintenance interval deployment surface generation module generates maintenance deployment tasks based on the information collected by the information collection module using the isolation switch condition judgment.

[0061] The maintenance interval five-defense verification module is completed by topological error prevention verification, based on the connection relationship of the wiring diagram of the primary equipment, to determine whether the maintenance deployment task is correct and give the judgment result.

[0062] The computer key communication module adopts serial communication mode to transmit the inspection and deployment tasks with correct judgment results to the computer key, and uses the computer key to open the corresponding lock.

[0063] The arming equipment and base installation module adopt a base padlock design.

[0064] In this embodiment, if Figure 1 As shown, the device isolates the equipment of the substation by using the air-open lock, operating handle lock, protective pressure plate lock and padlock provided by the defense equipment and the base installation module. The isolation method is reliable and convenient, and effectively eliminates the possibility of misoperation accidents by on-site staff. The correct maintenance tasks are generated by the information collection module and the maintenance interval defense surface generation module. The accuracy of the maintenance tasks is further guaranteed by the maintenance interval five-defense verification module. The opening and closing of the locks are established through the computer key communication module, and the maintenance work is transformed from the original human-controlled management mode that relies on the system and human active control to a technical-controlled management mode supervised and restricted by a third-party device, which effectively improves work efficiency and ensures work quality.

[0065] Specifically, the specific process of determining the isolation switch condition of the maintenance interval deployment surface generation module is as follows:

[0066] S01: Start generating commands;

[0067] S02: Acquisition device status;

[0068] S03: Five-defense logic check;

[0069] S04: Maintenance interval generation starts;

[0070] S05: Determine whether there is a circuit breaker in the topological connection between the device and other bays.

[0071] If there is a circuit breaker, determine whether the circuit breaker and disconnector are in the open position.

[0072] If there is no circuit breaker, determine whether the disconnector is in the open position;

[0073] S06: Generate a maintenance deployment task work order based on the judgment result of step S05.

[0074] If all conditions in step S05 are met, the maintenance interval topology is colored to complete the generation of the maintenance deployment task work order.

[0075] If the condition in step S05 is not met, the generation of the maintenance deployment task work order fails.

[0076] In this embodiment, if Figure 2 As shown, the isolating switch condition judgment is used as the basis for generating the maintenance deployment task work order for the maintenance interval deployment surface. The isolating switch condition judgment is based on the generation of the maintenance interval range determined by the isolating switches on each side of the topological connection of the maintenance equipment in the open position. The maintenance equipment includes circuit breakers, transformers, capacitors, voltage transformers, etc.

[0077] In actual applications, 10 typical equipment intervals were selected, including double-winding transformers, three-winding transformers, open-type circuit breakers, combined electrical circuit breakers, busbars, open-type voltage transformers, combined electrical voltage transformers, 10kV trolley switches, 10kV voltage transformer trolleys, and capacitor banks. Fifteen substations were selected for each type of equipment, and a total of 200 tests were conducted to test the success rate of maintenance interval generation. The specific situation is shown in Table 1 below.

[0078] Table 1 Maintenance interval generation success rate and judgment time

[0079]

[0080]

[0081] Through the results in Table 1 above, it is found that the average judgment time using the disconnector condition is 1.54s, the judgment time is short, and the efficiency is high. The success rate of generating the maintenance deployment task work order is 99.5%, which has a high success rate, improves the quality of substation maintenance work, and ensures work efficiency.

[0082] Specifically, the inspection steps of the maintenance interval five-prevention inspection module are as follows:

[0083] Step 1: Define the device type in the program code;

[0084] Step 2: Directly call the five-defense logic through the connection relationship to dynamically judge the current status of the device.

[0085] Step 3: Determine whether the maintenance interval generation result is correct and give the determination result.

[0086] In this embodiment, the maintenance interval five-protection verification module is completed in a topological anti-error verification manner. It makes a judgment based on the connection relationship of the wiring diagram of the primary equipment to determine whether the maintenance deployment task is correct and give a judgment result. Through the function of this module, the correctness of the maintenance deployment task work order is guaranteed, thereby further ensuring the maintenance quality. In the actual application process, the judgment rule is directly added to the code program to make the use of the device intelligent.

[0087] Specifically, the arming equipment and base installation module adopts a detachable arming base, including an air switch lock, an operating handle lock, a protective pressure plate lock, and a padlock. The air switch lock is installed at the switch position of the air switch 18, the operating handle lock is installed on the operating handle, the protective pressure plate is installed on the secondary equipment cabinet, and the padlock is installed on the corresponding lock holes of the air switch lock, the operating handle lock, and the protective pressure plate lock.

[0088] In this embodiment, the deployment tool and base installation module adopt a detachable deployment base, which can be installed and disassembled as needed, and the nuts in the screen cabinet are used to provide mechanical support. The deployment base can be disassembled into a single or connected in a row according to the maintenance work content. Either a single pressure plate or a row of pressure plates can be deployed, which is convenient for targeted deployment and reuse for the next maintenance work.

[0089] In actual use, different deployment bases are used for different equipment in the substation. The air switch lock is installed at the switch position of the air switch 18, so that the air switch 18 cannot be opened at will after the air switch lock is installed and the padlock is added, thereby ensuring the safety during the maintenance process and preventing safety accidents caused by misoperation. The operating handle lock is installed on the operating handle 25, so that 25 cannot be opened after the operating handle lock is installed and the padlock is added, thereby ensuring that the operating handle 25 is not touched by mistake. The protective pressure plate lock is installed on the secondary equipment cabinet, so that the switch on the cabinet will not change its state at will after the protective pressure plate lock is installed and the padlock is added, thereby avoiding the switch on the cabinet from being touched by mistake and ensuring safety during the maintenance process.

[0090] Specifically, the computer key communication module receives the correct maintenance deployment task through the communication adapter, and then opens the corresponding padlock through the communication adapter.

[0091] In this embodiment, the correct maintenance and deployment tasks are mainly received through the communication adapter. After the communication adapter receives the correct maintenance task, the corresponding lock on the communication adapter is connected and locked for deployment. At the same time, the lock code will be transmitted back to the topology connection relationship diagram and can be displayed at the corresponding position. The deployment work is completed and the maintenance begins. When the maintenance work is completed, the corresponding disarming work order is generated according to the maintenance task work order, and the communication adapter is used again to unlock each lock. Finally, the lock code is transmitted back and the disarming work is completed after verification. During the use of the device, the communication adapter establishes a connection with the padlock as an electronic key to realize the opening and closing of the padlock.

[0092] Embodiment 2

[0093] Specifically, the air-open lock includes an elastic lock pin 11, a lock pin guide end cover 12, a mounting sleeve 13, a spring clamping end 14, a clamping release spring 15, a lock core mounting structure 16, and a lock core 17. The elastic lock pin 11 is connected to the left side of the lock pin guide end cover 12, the mounting sleeve 13 is connected to the right side of the lock pin guide end cover 12, the spring clamping end 14 is mounted on the right end of the mounting sleeve 13, the clamping release spring 15 is located inside the mounting sleeve 13, one end of which is connected to the mounting sleeve 13, and the other end is mounted on the spring clamping end 14, the lock core mounting structure 16 is mounted on the right side of the spring clamping end 14, and the lock core 17 is installed in the lock core mounting structure 16, located inside the lock core mounting structure 16 and extending outward.

[0094] Specifically, a lock hole movable groove 161 is opened on the side of the lock core installation structure 16 , and a lock core buckle 171 is provided on the portion of the lock core 17 located inside the lock core installation structure 16 . The lock core buckle 171 is snapped into the lock hole movable groove 161 .

[0095] In this embodiment, the actual use structure of the air-opening lock is described, such as Figure 3 , Figure 4 As shown, it is a schematic diagram of the specific structure of the air switch lock. In actual use, the elastic lock pin 11 is installed at the switch toggle position of the air switch 18, which limits the switch position of the air switch 18 and avoids safety problems caused by accidental contact during maintenance.

[0096] In this embodiment, the lock core 17 can move in the lock core mounting structure 16, and during the movement, a force is applied to the spring clamping end 14. Under the action of this force, the compression and release spring 15 in the mounting sleeve 13 is subjected to pressure and elastically deforms, so that the elastic lock pin 11 opens. Under the action of the elastic force of the compression and release spring 15, the elastic lock pin 11 can be clamped in the switch position of the air switch 18. At the same time, the existence of the lock pin guide end cover 12 makes the switch of the air switch 18 unable to change its state, which plays a limiting role to avoid accidental contact. After the inspection is completed, the lock core 17 is operated to subject the compression and release spring 15 to a force again, and the air switch lock is removed.

[0097] Embodiment 3

[0098] Specifically, the operating handle lock includes a hinge 21, a left cloth protection cover 22, a right cloth protection cover 23, and a lock hole 24. The hinge 21 is fixedly installed in the middle position above the operating handle 25. The left cloth protection cover 22 is rotatably connected to the left side of the hinge 21, and the right cloth protection cover 23 is rotatably connected to the right side of the hinge 21. The left cloth protection cover 22 and the right cloth protection cover 23 have the same structure, and their structure is compatible with the structure of the operating handle 25. A lock hole 24 is provided at one end of the left cloth protection cover 22 and the right cloth protection cover 23 away from the hinge 21.

[0099] In this embodiment, if Figure 5 As shown, the position of the operating handle 25 is restricted by the rotation of the left cloth protection cover 22 and the right cloth protection cover 23, and it cannot be moved. A lock hole 24 is opened under the left cloth protection cover 22 and the right cloth protection cover 23 to facilitate the installation of a padlock, thereby preventing the operating handle 25 from moving during maintenance and deployment work, thereby ensuring maintenance safety.

[0100] Embodiment 4

[0101] Specifically, the protective pressure plate lock includes a left fixed plate 31, a right fixed plate 32, a spliced ​​fixed vertical rod 33, a padlock mounting rod 34, and a closed cover 35. The left fixed plate 31 is fixedly installed on the left side of the screen cabinet using screws, and the right fixed plate 32 is fixedly installed on the right side of the screen cabinet using screws. The left fixed plate 31 and the right fixed plate 32 have the same structure and are cylindrical in design. A fixing hole 311 is provided at the upper end thereof, and the screw is fixedly installed on the screen cabinet through the fixing hole 311. A connecting hole is provided on the side of the lower end thereof. The spliced ​​fixed vertical rod 33 is fixed by screws passing through the connecting hole on the left fixed plate 31, and the padlock mounting rod 34 is fixed by screws passing through the connecting hole on the right fixed plate 32. There are multiple closed covers 35, and the closed covers 35 are rotatably connected to the spliced ​​fixed vertical rod 33. The first padlock hole is provided at the right end of the closed cover 35.

[0102] In this embodiment, if Figure 6As shown, there are multiple switches in the secondary equipment cabinet. During the inspection and maintenance process, when the switch in a certain area is operated, it is very likely to touch the switch in the nearby area, causing a safety accident and threatening the stable and effective operation of the power grid. A protective pressure plate lock is set to block the corresponding position and lock it with a padlock.

[0103] In this embodiment, the closed cover 35 of the protective pressure plate lock is installed on the spliced ​​fixed vertical rod 33 on the left side and is locked with a padlock on the right side. The protective pressure plate lock adopts the design of spliced ​​fixed vertical rod 33 and can be used selectively according to the area to be covered when in use, and can be suitable for different maintenance scenarios.

[0104] Specifically, the spliced ​​fixed vertical rod 33 is a cylindrical structure, and its diameter is adapted to the diameter of the lower end of the left fixed plate 31, and includes a plurality of vertical rods of the same length, the upper end of the vertical rod has the same diameter as the lower end of the vertical rod, and its inner diameter is the same as the outer diameter of the lower end of the left fixed plate 31. The middle of the vertical rod is rotatably connected to the closed cover 35, and the outer diameter of the middle position of the vertical rod is the same as the outer diameter of the lower end of the left fixed plate 31.

[0106] In this embodiment, the upper end of the spliced ​​fixed vertical rod 22 is connected to the bottom of the left fixed plate 31 and can be fixed with screws. The length of the spliced ​​fixed vertical rod 33 is selected and adjusted according to the number of protective pressure plate locks actually installed on the screen cabinet, and has a wide range of applications.

[0107] In general, the substation secondary intelligent deployment control device is upgraded and expanded based on the existing five-defense system principle of the substation, adding a maintenance interval verification module, adding a maintenance deployment control adapter, maintenance deployment authorization key, and locking locks and accessories. It can realize the parallel deployment of secondary equipment such as pressure plates and operating handles, and quickly complete the deployment work. It is upgraded and transformed on the original more mature system. The new device has a high deployment completeness rate, fast speed, smooth operation, and efficient completion of the task.

[0108] The maintenance work is transformed from the original human-controlled management mode that relies on systems and people's active control to a technical-controlled management mode supervised and restricted by third-party devices. The management issues such as the deployment of security measures and forced locking of maintenance equipment during the maintenance process are solved from all-round and multi-dimensional perspectives. By adding multiple maintenance modules, sub-modules and adapters, authorization keys, locks and accessories, the deployment and utilization devices are physically forced to manage, realizing intelligent management. Since this device is an upgrade and transformation of the relatively mature existing five-defense system, it has extremely high reliability, the physical structure used is simple, it can operate independently, does not rely on external interfaces, the data collection source of on-site equipment is stable and reliable, and the requirements for the operating system and operating environment are low. It is a very stable and reliable device.
