Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a fast protection and control device with an optical fiber interface. Background Technology

[0002] Fast protection and control devices are key equipment used in power systems to realize relay protection and control functions. They are mainly used in the monitoring and protection of transformers. They can detect and protect electrical equipment such as lines and transformers based on parameters such as current and voltage of power facilities, such as overcurrent protection and differential protection. They are characterized by fast action speed, high reliability and strong anti-interference ability. They are widely used in substations, distribution networks and other scenarios to ensure the safe and stable operation of power systems.

[0003] Existing fast protection and control devices connect to various devices via external interfaces. These devices typically include junction boxes and other components. To facilitate quick connection of terminals, existing junction boxes use springs or other components to move pressure plates. When connecting terminals, tools like screwdrivers are used to separate the contacts from the pressure plates. The pressure plates are then moved by the springs or other elastic components to secure the wiring. Since each pressure plate is controlled by a single elastic component, each pressure plate must be controlled individually for securing. It is not possible to simultaneously control multiple pressure plates to disconnect from the contacts. This tool-based securing method adds extra time to the wiring connection process.

[0004] Therefore, there is an urgent need for a fast protection and control device with a fiber optic interface to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fast protection and control device with an optical fiber interface to solve the problem mentioned in the background art that it is not possible to simultaneously control the release of multiple pressure plates from the contacts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fast protection and control device with an optical fiber interface, comprising a control body and a connection port, wherein an mounting plate and a junction box are installed on one side of the control body, a contact is installed inside the junction box, a pressure plate is slidably connected to the outer surface of the contact, and a moving rod is fixedly installed on the outer surface of the pressure plate;

[0007] Both sides of the junction box are fixedly installed with connecting plates. The internal threads of the connecting plates are connected to control rods. The outer surface of the control rods is rotatably connected to push plate one. The outer surface of the connecting plates is fixedly installed with positioning rods. The outer surface of the positioning rods is slidably connected to push plate two.

[0008] A fixing ring is fixedly installed on the outer surface of the movable rod, a spring is sleeved on the outside of the movable rod, a fixing rod is rotatably connected inside the fixing ring, and a connecting piece is fixedly installed on the outer surface of the fixing rod.

[0009] Preferably, the outer surface of the movable rod is slidably connected to the interior of the junction box, and the outer surface of the pressure plate is slidably connected to the interior of the junction box.

[0010] Preferably, the connecting plates are symmetrically arranged on both sides of the junction box, and a set of control rods and positioning rods are arranged adjacent to each other on the connecting plates.

[0011] Preferably, a baffle is fixedly installed at one end of the positioning rod, the outer surface of one set of positioning rods is slidably connected to the interior of push plate one, and the outer surface of one set of control rods is rotatably connected to the interior of push plate two.

[0012] Preferably, the push plate one and the push plate two are disposed on both sides of the connecting rod, and the outer surface of the connecting piece is in contact with the upper surface of both the push plate one and the push plate two.

[0013] Preferably, a control handle is fixedly installed on the outer surface of the connecting piece, and a limit plate is fixedly installed on one side of both the first push plate and the second push plate, with the lower surface of the connecting piece in contact with the upper surface of the limit plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model discloses a fast protection and control device with an optical fiber interface. Through the cooperation of the control rod, connecting piece, push plate one, and push plate two, the control rod at different positions can control the movement of push plate one and push plate two. When the connecting piece one contacts push plate one, the movement of push plate one can control multiple sets of moving rods to move quickly. At this time, multiple sets of pressure plates are disengaged from the contacts. Similarly, push plate two moves, and after the line contacts the contact, the connecting piece is rotated. At this time, the connecting piece contacts push plate one and quickly resets under the action of the spring to clamp the connecting line. It is more convenient to use and realizes the function of quickly separating the pressure plate and the contact, which helps to reduce the time of line connection.

[0017] 2. The present invention provides a fast protection and control device with an optical fiber interface. By setting a limiting plate and other components, the limiting plate can limit the rotation of the connecting piece. At this time, the connecting piece will not be disconnected from the outside of the push plate one or push plate two when it rotates, which increases the stability of the connecting piece during adjustment. At this time, controlling the movement of push plate one and push plate two can control the movement of the pressure plate, which makes it convenient to control the movement of the pressure plate separately.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a rapid protection and control device with an optical fiber interface. The device includes a control body 1 and a connection port 2. An mounting plate 3 and a junction box 4 are installed on one side of the control body 1. A contact 5 is installed inside the junction box 4. A pressure plate 6 is slidably connected to the outer surface of the contact 5. A moving rod 7 is fixedly installed on the outer surface of the pressure plate 6. The outer surface of the moving rod 7 is slidably connected to the inside of the junction box 4. The outer surface of the pressure plate 6 is slidably connected to the inside of the junction box 4. The device can be connected to an external optical fiber jack through the connection port 2. The pressure plate 6 can move under the action of the moving rod 7 to place the metal piece of the connecting wire outside the contact 5. Then, the metal piece of the connecting wire can be pressed tightly by the moving rod 7 and the pressure plate 6.

[0026] Connecting plates 8 are fixedly installed on both sides of junction box 4. Control rods 9 are threadedly connected to the inside of connecting plates 8. Push plates 10 are rotatably connected to the outer surface of the control rods 9. Positioning rods 11 are fixedly installed on the outer surface of connecting plates 8. Push plates 12 are slidably connected to the outer surface of the positioning rods 11. Connecting plates 8 are symmetrically arranged on both sides of junction box 4. A set of control rods 9 and positioning rods 11 are arranged adjacently on the connecting plates 8. Each set of connecting plates 8 has a set of control rods 9 and positioning rods 11 on its outside. The rotation of a set of control rods 9 allows for control... Push plate 10 or push plate 2 12 moves outside the connecting plate 8. Both ends of a set of push plates 10 or push plate 2 12 are controlled by control rod 9 and positioning rod 11 respectively. Control rod 9 controls the movement of push plate 10 or push plate 2 12, and positioning rod 11 assists in the movement of one end of push plate 10 or push plate 2 12. Push plate 10 and push plate 2 12 can move separately under the action of their respective control rods 9. For example, when a set of push plates 10 moves to the top, the other set of push plates 2 12 is at the bottom, and vice versa.

[0027] A baffle 17 is fixedly installed at one end of the positioning rod 11. The outer surface of a set of positioning rods 11 is slidably connected to the inside of the push plate 10. The outer surface of a set of control rods 9 is rotatably connected to the inside of the push plate 12. The baffle 17 can limit one end of the positioning rod 11. A knob is provided at one end of the control rod 9. By rotating the knob, the control rod 9 can be rotated. By rotating the control rod 9 at different positions, the push plate 10 and the push plate 12 can be moved up and down respectively.

[0028] A fixing ring 13 is fixedly installed on the outer surface of the moving rod 7. A spring 14 is sleeved on the outside of the moving rod 7. One end of the spring 14 is fixedly installed inside the junction box 4, and the other end of the spring 14 is fixedly installed on the outer surface of the fixing ring 13. Under the push of the spring 14, the pressure plate 6 can be controlled to approach the contact 5. When the metal piece of the connecting wire enters the position of the contact 5, the spring 14 can press and fix it.

[0029] A fixing rod 15 is rotatably connected inside the fixing ring 13. A connecting piece 16 is fixedly installed on the outer surface of the fixing rod 15. A control handle 18 is fixedly installed on the outer surface of the connecting piece 16. The connecting piece 16 can move with the pressure plate 6. The orientation of the connecting piece 16 can be adjusted by rotating the control handle 18. When the position of the connecting piece 16 is limited, the position of the pressure plate 6 is fixed.

[0030] Push plate 10 and push plate 2 12 are set on both sides of the connecting rod. The outer surface of the connecting piece 16 is in contact with the upper surface of push plate 10 and push plate 2 12. The connecting piece 16 is normally connected to a set of push plates 10 or push plate 2 12. When the connecting line is connected, push plate 10 or push plate 2 12 is controlled to move. At this time, push plate 10 or push plate 2 12 can control the movement of the connecting piece 16. Multiple sets of pressure plates 6 can be controlled to move synchronously through the connecting piece 16. The position of the pressure plates 6 does not need to be controlled by a separate tool. When the connecting line under a set of pressure plates 6 is installed, the control handle 18 is rotated. At this time, a set of connecting pieces 16 is disengaged from push plate 10. Under the push of spring 14, the connecting piece 16 moves and falls above push plate 2 12. Similarly, push plate 2 12 can also be controlled accordingly.

[0031] Limiting plates 19 are fixedly installed on one side of push plate 10 and push plate 2. The lower surface of the connecting piece 16 is in contact with the upper surface of the limiting plate 19. The limiting plate 19 can limit the rotation of the connecting piece 16. At this time, the connecting piece 16 will not be disconnected from the outside of push plate 10 or push plate 2 when it rotates, which increases the stability of the connecting piece 16 during adjustment.

[0032] Working principle: When installing the connecting wire, rotate the control lever 9 to control the movement of push plate 10 or push plate 2 12. At this time, push plate 10 or push plate 2 12 can control the movement of the moving lever 7 through the connecting piece 16, which can control multiple sets of pressure plates 6 to move synchronously. Then the connecting wire is connected. After connecting one set of connecting wires, rotate the control handle 18. At this time, a set of connecting pieces 16 disengages from push plate 10 or push plate 2 12. At this time, the connecting piece 16 moves downward under the action of spring 14. Spring 14 controls the pressure plate 6 to approach the contact 5 to fix the connecting wire. At this time, the connecting piece 16 controlled by spring 14 can contact the push plate 10 or push plate 2 12 below.
