Description

Technical Field

[0001] This utility model relates to the field of protection device technology, specifically to an overvoltage protection device assembly. Background Technology

[0002] Overvoltage refers to a prolonged voltage fluctuation where the root mean square value of AC voltage at power frequency increases by more than 10% of the rated value and lasts for more than one minute. Overvoltage typically occurs as a result of load switching. During normal operation, it occurs when inductive or capacitive loads are switched on or off. Sudden changes in the circuit and electromagnetic states of a power system are the fundamental cause of overvoltage. Overvoltages are broadly classified into external and internal overvoltages. Studying the causes of various overvoltages in a power system, predicting their amplitude, and taking measures to limit them are prerequisites for determining the insulation coordination of the power system, and are of great significance for both electrical equipment manufacturing and power system operation. Both external and internal overvoltages are influenced by many random factors, requiring data acquisition through calculation, simulation, and field measurements, combined with specific power system conditions, and overvoltage prediction using probabilistic statistical methods. To address the causes of overvoltages, the power system must take protective measures to limit their amplitude. These include installing lightning rods, surge arresters, reactors, and adding parallel resistors to switch contacts to ensure proper insulation coordination and safe operation of the power system.

[0003] A sudden increase in voltage can cause serious damage to the controller, resulting in flashover. Overvoltage can also cause the controller to catch fire, and if not dealt with in time, the fire can spread and cause even greater losses. Utility Model Content

[0004] The purpose of this invention is to provide an overvoltage protection device assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overvoltage protection device assembly, including a controller and a button, a protector detachably connected to the outer periphery of the controller, a stop gate rotatably connected to the protector, plugs slidably connected to both sides of the stop gate, a slide rod provided at the input end of the plug, a button detachably connected to the slide rod, a socket provided on the protector corresponding to the plug, the plug being inserted into the corresponding socket, and an air port provided on the side wall of the protector.

[0006] Preferably, the gate has a sliding opening, and a sliding rod is slidably connected inside the sliding opening. The sliding rod has the same diameter as the sliding opening and passes through the sliding opening.

[0007] Preferably, a circular plate is detachably connected to the sliding rod on the inner side of the gate, and an extension plate is provided on the circular plate of the sliding rod. The extension plates are respectively located on the two side walls of the circular plate. A first spring is sleeved on the sliding rod. One end of the first spring is detachably connected to the circular plate, and the other end of the first spring is detachably connected to the corresponding gate.

[0008] Preferably, a rocker is rotatably connected to the extended plate of the circular plate, and the other end of the rocker is rotatably connected to a rotating seat, which is welded to a connecting seat.

[0009] Preferably, the connector is welded to the plug, and a protrusion is provided at the connection between the connector and the rotating seat, with the protrusion facing the door.

[0010] Preferably, the gate is provided with a fixed seat, a plug is slidably connected to the fixed seat, a limit rod is provided on the fixed seat, the protrusion is slidably connected to the limit rod, and a second spring is sleeved on the limit rod, the second spring being located between the protrusion and the fixed seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By installing a protector on the outer periphery of the controller, the protector and the barrier can enclose the controller, thus sealing it off and preventing direct exposure to the environment. During normal operation, the barrier is closed, effectively sealing the protector. In the event of an explosion due to overvoltage, the explosion will be contained within the protector's protection zone and will not spread outwards, protecting the external environment. The protector and barrier form a closed space, reducing the oxygen content inside the protector. This minimizes the combustion range after an explosion, preventing further combustion and fire. During maintenance, pressing a button moves a sliding rod into the protector, causing a circular plate to pull a lever, allowing the plug to be unplugged and the barrier to open. This system can be configured to prevent unauthorized opening of the barrier. Attached Figure Description

[0018] 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.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: an overpressure protection device assembly, including a controller 1 and a button 4. A protector 2 is detachably connected to the outer periphery of the controller 1. A stop valve 3 is rotatably connected to the protector 2. Plugs 11 are slidably connected to both sides of the stop valve 3. A slide rod 6 is provided at the input end of the plug 11. The button 4 is detachably connected to the slide rod 6. A socket 7 is provided on the protector 2 corresponding to the plug 11, and the plug 11 is inserted into the corresponding socket 7. An air port 5 is provided on the side wall of the protector 2. By setting the protector 2 outside the controller 1, the protector 2 can seal off the surrounding area of ​​the controller 1. The stop valve 3 on the protector 2, when closed, forms a closed space with the protector 2, thereby limiting the range of explosion and fire caused by overpressure of the controller 1, thus protecting the controller 1. This design prevents the explosion or fire from spreading too far, reducing property damage.

[0020] The stop gate 3 has a sliding opening 9, and a sliding rod 6 is slidably connected inside the sliding opening 9. The sliding rod 6 has the same diameter as the sliding opening 9 and passes through the sliding opening 9. By opening the sliding opening 9 on the stop gate 3, the sliding rod 6 can extend and retract within the sliding opening 9. When the sliding rod 6 extends and retracts, it can drive the connected rocker arm to move. The rocker arm can then push and pull the plug 11, allowing the plug 11 to be pulled out or inserted into the socket 7, thereby achieving control over the plug 11.

[0021] A circular plate 14 is detachably connected to the slide rod 6 on the inner side of the stop 3. An extension plate 13 is provided on the circular plate 14 of the slide rod 6, with the extension plates 13 located on the two side walls of the circular plate 14. A first spring 8 is sleeved on the slide rod 6. One end of the first spring 8 is detachably connected to the circular plate 14, and the other end is detachably connected to the corresponding stop 3. By providing the circular plate 14 on the slide rod 6, with a diameter larger than that of the slide rod 6, the first spring 8 will not dislodge after being sleeved on the slide rod 6. The first spring 8 can then drive the slide rod 6 to move outwards, which in turn pulls the rocker arm, which in turn pushes the plug 11 into the socket 7.

[0022] A rocker arm 12 is rotatably connected to the extension plate 13 of the circular plate 14. The other end of the rocker arm 12 is rotatably connected to a rotating seat 19, which is welded to a connecting seat 15. The extension plate 13 allows for connection with the rocker arm, thus enabling the rocker arm to be controlled.

[0023] The connector 15 is welded to the plug 11. A protrusion 18 is provided at the connection between the connector 15 and the rotating seat 19, with the protrusion 18 facing the stop 3. The plug 11 can be inserted into the socket 7 to fix the stop 3.

[0024] A fixed seat 10 is provided on the stop 3, and a plug 11 is slidably connected to the fixed seat 10. A limit rod 17 is provided on the fixed seat 10, and a protrusion 18 is slidably connected to the limit rod 17. A second spring 16 is sleeved on the limit rod 17, and the second spring 16 is located between the protrusion 18 and the fixed seat 10. The plug 11 can be easily pushed by the second spring 16, thereby allowing the edge plug 11 to be pulled out. The torque of the second torsion spring is less than that of the first torsion spring, so it will not affect the pushing action of the first spring 8.

[0025] Working principle: By installing a protector 2 on the outer periphery of the controller 1, the protector 2 and the barrier 3 can enclose the controller 1, thus sealing it off and preventing it from being directly exposed to the environment. When the protector 2 is in normal use, the barrier 3 is closed, which can seal the protector 2. If the controller 1 explodes due to overpressure, it will be within the protection range of the protector 2 and will not spread outward, thus protecting the external environment. The protector 2 and the barrier 3 can form a closed space, thereby reducing the oxygen content inside the protector 2. After the controller 1 explodes, its combustion range can be reduced, thus preventing the controller 1 from continuing to burn and preventing fire. During maintenance, pressing button 4 will move the slide bar 6 into the protector 2. The circular plate 14 will drive the rocker arm to pull the plug 11, allowing the plug 11 to be pulled out of the socket 7, thereby opening the barrier 3. By setting it, the arbitrary opening of the barrier 3 can be prevented.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
