Technical Field

[0001] The invention relates to the technical field of high-voltage switch cabinets, and in particular to a gas pressure regulating mechanism for a high-voltage switch cabinet. Background Art

[0002] High-voltage switchgear is an electrical device used to control, protect and isolate high-voltage circuits. It is widely used in power systems such as substations, factories and large buildings.

[0003] The air pressure regulating mechanism for high-voltage switchgear is mainly used to maintain the air pressure inside the cabinet stable and ensure the safe operation of the equipment under high-voltage environment. In high-altitude areas or when an internal fault occurs, the air pressure inside the cabinet may change.

[0016] Working principle: When performing air pressure balancing, since the air pressure inside the high-voltage switch cabinet is low, while the pressure of the pressure regulating tank is high, the gas inside the pressure regulating tank will enter the interior of the installation tube through the installation elbow, and use the air pressure to push the sliding plate to move in the direction of the connecting pipe, so that the sliding plate is no longer pressed against the inner wall of the installation tube. At this time, the gas will enter the installation tube through the vent hole and then enter the interior of the high-voltage switch cabinet through the interior of the installation tube, so that gas can be introduced into the interior of the high-voltage switch cabinet. When the gas pressure inside the pressure regulating tank is reduced, the limit plate is pushed downward under the reaction force of the push spring, so that the piston can be pushed downward, and then the gas under the piston in the pressure regulating tank can always maintain the pressure, so that the internal air pressure of the high-voltage switch cabinet can be automatically balanced;

[0017] When inflating the interior of the pressure regulating tank, start the air pump, and the output end of the air pump ventilates the interior of the connecting air pipe, thereby driving the impeller to rotate, and the impeller can drive the rotating shaft to rotate after the rotation, and the rotating shaft can drive the fixed cylinder to rotate, and the fixed cylinder rotation drives the sliding square plate to rotate, and the sliding square plate rotation drives the inner rod to rotate, and the inner rod rotation can drive the rotation, and after the rotation, the filter plate can be cleaned, and the cleaned dust can be removed by twisting the connecting hexagonal head after the inflation is completed, and the connecting air pipe can be removed, and when the gas enters the interior of the installation connecting pipe When the piston is pushed upward, the gas will enter the pressure regulating tank and stop being filled with gas. When the pressure inside the pressure regulating tank is sufficient, the gas will stop being filled into the pressure regulating tank. Under the action of the gas pressure inside the pressure regulating tank, the plug plate can be driven to move into the pressure regulating tank, thereby sealing the plug plate again and preventing the gas inside the pressure regulating tank from being discharged.

[0018] The present invention provides a gas pressure regulating mechanism for a high-voltage switch cabinet. It has the following beneficial effects:

[0019] 1. The present invention realizes that the gas in the pressure regulating tank can be automatically discharged into the high-voltage switch cabinet by utilizing the difference in air pressure between the inside of the pressure regulating tank and the inside of the high-voltage switch cabinet, thereby ensuring the gas pressure in the high-voltage switch cabinet. The present invention has a simple structure, low cost, and is easy to replace. It is relatively easy to repair or replace after damage, and does not delay the use of the switch cabinet.

[0020] 2. The present invention filters the drawn air through the filter plate, and drives the impeller to rotate through the airflow. The rotation of the impeller drives the elastic component to rotate, and then drives the cleaning brush to rotate, so that the dust attached to the filter plate can be scraped off, and the dust can be removed by disassembling the connecting air pipe. Therefore, the gas entering the high-voltage switch cabinet is clean and tidy, thereby avoiding damage to the high-voltage switch cabinet caused by dust. BRIEF DESCRIPTION OF THE DRAWINGS
