Description

Technical Field

[0001] The present invention relates to the field of relay protection in a centralized control station, and particularly to a relay protection setting verification and confirmation device with a protection structure for a centralized control station. Background Art

[0002] The remote device for verifying relay protection settings based on a centralized control station is an automated device mainly used for remotely verifying the settings of relay protection devices in a power system. This device establishes a dynamic database model to achieve remote operation and management of the settings. It can verify the settings of relay protection equipment in the power system at the centralized control station, ensuring that the equipment can act accurately and quickly during a fault and protecting the safe operation of the power system. The application of this device improves the efficiency and accuracy of setting verification, reduces the risk of human operation errors, and is an important part of the development of power system automation and intelligence.

[0003] Chinese Patent with Publication No. CN211293095U discloses a device and system for verifying relay protection settings before and after maintenance of a relay protection device, including a power supply module and an MCU module. The printing interface of the relay protection device is connected to the parallel interface of the verification device. The MCU module compares whether the settings before and after maintenance sent from the relay protection device are the same and displays the comparison result through a display module. The verification process of this device and system is rapid, simple, and accurate, without the need for manual verification, achieving automatic verification, with a simple structure, easy implementation, and low cost.

[0004] When the setting verification device of the above patent is installed in a centralized control station, since the setting verification device can be remotely verified, the display screen and buttons installed on the outer wall of the setting verification device will be exposed outdoors for a long time, which is not convenient for protection. Relying solely on the protection panel connected by an axis in front of the display screen and buttons, the protection ability is weak, and it cannot increase the service life of the setting verification device when it is installed in the centralized control station for a long time. The protection panel connected by an axis is prone to looseness and detachment. Summary of the Invention

[0005] The purpose of the present invention is to provide a relay protection setting verification and confirmation device with a protection structure for a centralized control station. After restricting the rotation of the handle of the protection plate, the handle is pulled horizontally to drive the protection piece and the connected transmission rod to extend out of the housing. When the protection piece slides horizontally, it will drive the corresponding gear of the protection plate to rotate, and the rotation causes the protection plate to unfold as the protection piece is pulled, solving the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A centralized control station relay protection setting verification and confirmation device with a protection structure, including a housing and a verification system built inside the housing. An installation plate is welded at the front end of the housing. A protection plate is provided on one side of the front end of the installation plate. Gears are provided at both upper and lower ends on the other side of the front end of the installation plate. A protection plate rotatably connected by a first connecting shaft is arranged between the two gears facing the protection plate. An installation groove is provided on the front end of the protection plate facing the protection plate side. A transmission bar rotatably connected to the protection plate through a fourth connecting shaft is provided at the front end of the installation groove. The transmission bar can rotate around the fourth connecting shaft to adjust the orientation of the transmission bar. When the transmission bar is rotated and taken out of the installation groove, it is convenient to remove the restriction on the protection plate. After removing the restriction on the protection plate, the protection plate can be pulled horizontally.

[0007] Preferably, transmission rods are welded at the four corner positions of the protection plate facing the housing. Two of the transmission rods are respectively close to the two gears. Tooth grooves fixedly welded to the outer walls of the transmission rods close to the gears are meshed with the outside of the gears. When the protection plate is pulled horizontally, the transmission rods can be slid out of the housing. When the transmission rods are taken out of the housing, they can drive and cause the gears to rotate.

[0008] Preferably, a tray is arranged inside the protection plate. The tray is rotatably connected to the protection plate through a third connecting shaft. The tray can rotate around the third connecting shaft to slide out of the protection plate.

The tray can facilitate the placement of items through the exposed first groove, facilitate the maintenance of maintenance personnel, and facilitate the placement of auxiliary equipment for maintenance personnel.

[0010] Preferably, bolts are arranged at the four corner positions inside the installation plate. A second groove is recessed in the protection plate inside towards the installation plate. The recessed position of the second groove overlaps with the bolts at the four corner positions of the installation plate. The protection plate can overlap with the bolts through the second groove.

[0011] Preferably, a magnet is welded in the middle of the upper end of the fourth connecting shaft. The magnet is magnetically connected to the transmission bar. The transmission bar can rotate around the fourth connecting shaft to adjust the orientation and angle of the transmission bar. After the transmission bar rotates and contacts the magnet, the magnet can be magnetically connected to the transmission bar to fix the transmission bar.

[0012] Preferably, a handle is provided at the front end of the outside of the transmission bar. The handle is rotatably connected to the transmission bar through a second connecting shaft. Rotating the handle from the front end of the transmission bar causes the handle to rotate around the second connecting shaft. The rotation of the handle can facilitate pulling the fourth connecting shaft.

[0013] Preferably, one side of the outer upper end and the lower end of the other outer side of the fourth connecting shaft are both welded with limiting bars, and the transmission bar can be restricted by a pair of limiting bars to limit the rotation direction and angle of the transmission bar.

[0014] The present invention provides another technical solution: a drainage system of a centralized control station relay protection setting value verification and confirmation device with a protection structure, wherein the verification system comprises a setting value reading module, a setting value storage module, a setting value comparison module, a double confirmation logic module, a warning module, a visual display module, a communication module, a log recording module, a permission management module and a self-diagnosis module, wherein:

[0015] Fixed value reading module: can remotely connect to the relay protection device in the centralized control station and accurately read its current running fixed value information;

[0019] Warning module: When the fixed value comparison module finds inconsistency or an abnormal situation occurs during the confirmation process of the double confirmation logic module, it can issue an alarm message in time;

[0020] Visual display module: displays the comparison results of the fixed value comparison module, the device operation status, and the alarm information of the alarm module to the operation and maintenance personnel in the form of an intuitive graphical interface or report;

[0021] Communication module: establishes communication connection between the remote confirmation device and the relay protection device of the centralized control station, the control center and the operation and maintenance personnel terminal;

[0022] Log recording module: records in detail various information during the operation of the fixed value reading module, fixed value comparison module and double confirmation logic module;

[0023] Permission management module: divide the permissions of the personnel using the device into read permission, modification permission and confirmation permission. Different permissions correspond to different operation scopes.

[0024] Self-diagnosis module: Regularly test the hardware and software of the remote confirmation device to check whether the communication module is normal and whether each module is operating normally, so as to promptly discover problems with the device itself.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The front display screen and buttons of the outer shell of the present invention are wrapped by a protection plate. After the remote confirmation device is installed in the centralized control station, when it is not in use, the protection plate protects the outer shell, the front display screen and the buttons. However, when the remote confirmation device needs to be operated, after rotating and pulling the handle, the protection plate can rotate through the transmission of the gear. The rotation of the gear can drive the protection plate between the two gears to rotate. The rotation of the protection plate can unfold and expose the front display screen and buttons of the outer shell. Moreover, during the horizontal pulling process of the transmission bar, the protection piece will also slide horizontally along with the transmission bar. The protection piece is distributed around the front display screen and buttons of the outer shell in cooperation with the protection plate, and can protect the area around the front buttons of the outer shell when pressed, so as to cope with the use in different environments and improve the protection effect of the remote confirmation device.

[0027] 2. The protection piece of the present invention is pulled as the handle moves horizontally. After the protection piece moves horizontally and away from the mounting piece, the positions of the bolts installed at the four corners of the mounting piece will be exposed. When the remote confirmation device is not in use, the bolts can be protected. When disassembly and installation are required, pulling the protection piece horizontally can facilitate the disassembly of the bolts. Moreover, after the protection piece slides horizontally and the protection plate unfolds, the tray can rotate around the third connecting shaft inside the protection plate. The rotation is convenient for the user to place items on the upper end of the unfolded tray, facilitating the user to operate the remote confirmation device alone. At the same time, during the horizontal pulling process of the protection piece, the protection piece will pull the lamp bar out of the outer shell through the mounting strip. The inclined lamp bar can directly illuminate the front display screen and buttons of the outer shell, and also illuminate the items placed on the upper end of the tray. Moreover, it can also provide illumination when disassembling and fixing the bolts at the four corners of the mounting piece. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0038] The present invention will be further described below in conjunction with specific embodiments.

[0039] Embodiment 1

[0040] As Figure 1 and Figure 3 shown, a centralized control station relay protection setting verification and confirmation device with a protection structure in this embodiment includes an outer shell 1. A verification system is arranged inside the outer shell 1. Mounting pieces 2 are arranged around the front end of the outer shell 1, and the mounting pieces 2 are fixedly welded to the front end of the outer shell 1. When installing and fixing the outer shell 1, bolts pass through the mounting pieces 2 at the four corners of the outer shell 1, pass through and are embedded in the installation positions to complete the fixation. An air-cooled heat dissipation is arranged at the rear end inside the outer shell 1. Starting the air-cooled heat dissipation can make the heat inside the outer shell 1 discharge from the rear end of the outer shell 1. Heat dissipation fins are arranged on both sides of the outer wall of the outer shell 1, and the heat dissipation fins are fixedly bonded to the outer wall of the outer shell 1 through glue. When the air-cooled heat dissipation discharges heat, the heat dissipation fins can assist the air-cooled heat dissipation to discharge the heat inside the outer shell 1;

[0041] Among them, a protection piece 3 is arranged on one side of the front end of the mounting piece 2, and gears 15 are arranged at both the upper and lower ends of the other side of the front end of the mounting piece 2. A protection plate 6 is arranged between the two gears 15 towards the protection piece 3. When the operation and maintenance personnel remotely use the remote confirmation device, there is no need to use the display screen and buttons electrically connected to the front end of the outer shell 1. The display screen and buttons can be wrapped and protected by the protection plate 6. As Figure 1 and Figure 4As shown, the centers of the two gears 15 are rotatably connected to the other side of the protection plate 6 through the first connecting shaft 9. Driving the gears 15 can cause the gears 15 to rotate, and the rotation of the gears 15 can drive the protection plate 6 to unfold after being transmitted through the first connecting shaft 9;

Tooth grooves are arranged on the outer walls of the transmission rods 12 close to the gears 15, and the tooth grooves welded on the outer walls of the transmission rods 12 are meshed with the outside of the gears 15. When pulling the protection piece 3 and making the transmission rods 12 extend out of the housing 1, the tooth grooves will drive the gears 15 to rotate, and the rotation of the gears 15 can drive the protection plate 6 to flip, and the protection plate 6 will rotate and unfold synchronously during the pulling process of the protection piece 3;

After the tray 11 is rotated and unfolded to the outside of the protection plate 6, the first groove 16 and the tray 11 will rotate together with the third connecting shaft 18 as the center of the circle, and rotate and unfold to the outside of the protection plate 6;

[0048] In order to facilitate the wrapping of the bolts at the four corners of the mounting piece 2, a second groove 19 is recessed in the inner part of the protection piece 3 towards the position of the mounting piece 2. The second groove 19 is located at the four corners of the protection piece 3, and the recessed position of the second groove 19 overlaps with the bolts at the four corners of the mounting piece 2.
