Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PT cabinets, in particular to a fireproof PT cabinet. Background Art
[0002] PT cabinet, also known as voltage transformer cabinet, is an important equipment in the power system. Its main function is to convert high voltage into standard secondary voltage according to a certain ratio, usually 100V or lower, for protection, measurement and instrumentation. This conversion process is achieved through voltage transformers, which are connected in parallel in high-voltage circuits. In normal operation, the secondary winding is close to an open circuit state, ensuring the safety of the equipment.
[0003] When the PT cabinet is in use, fireproof materials are generally used to prevent external fires. In areas with large temperature differences, there will be moisture inside. If moisture exists for a long time, it will damage the internal components. A desiccant bag can be placed inside to absorb a certain amount of moisture. However, the internal space of the PT cabinet is limited, and the components may occupy most of the space, making it inconvenient to replace the desiccant bag. Therefore, those skilled in the art provide a fireproof PT cabinet to solve the problem raised. Utility Model Content

[0005] The utility model provides a fireproof PT cabinet adopting the following technical solutions:
[0006] A fireproof PT cabinet comprises a PT cabinet, wherein two side openings are symmetrically provided on both sides of the PT cabinet, a plug board is horizontally inserted in the side opening, a placement frame is fixedly installed on one side of the plug board, a cover plate is fixedly installed on the other side of the plug board, a desiccant is arranged in the placement frame, four horizontal cylinders are fixedly installed on the cover plate, eight horizontal columns are symmetrically fixedly installed on both sides of the PT cabinet, the horizontal columns are slidably inserted in the horizontal cylinders, a spring is sleeved on the horizontal column, and the spring is arranged in the horizontal cylinder, so that the desiccant can be conveniently replaced externally.
[0007] Preferably, connecting rods are fixedly installed between the four adjacent transverse cylinders, and the four connecting rods are arranged in a rectangular shape, so that the cover plate can be easily moved by the connecting rods.
[0008] Preferably, the plug plate and the side opening are matching components, and the plug plate and the side opening are of equal thickness, and can be sealed to ensure the integrity of the PT cabinet.
[0009] Preferably, two mounting blocks are symmetrically fixedly mounted on one side of the cover plate, and the two mounting blocks and the cover plate are fixedly connected to the PT cabinet by bolts, so as to fix the cover plate and prevent it from being opened by mistake.
[0010] Preferably, the front cross-section of the placement frame is set to an "L"-shaped structure, and the side of the placement frame is set to a grid shape, which is convenient for placing the desiccant and also convenient for the desiccant to contact with the internal air.
[0011] In summary, the utility model includes the following beneficial technical effects:
[0012] The desiccant can be inserted into the placement frame from the top. When the desiccant needs to be placed or replaced, the placement frame and the plug-in plate can be moved outward along the side opening by toggling the connecting rod. The placement frame can be exposed to the outside of the PT cabinet, and the desiccant can be taken and placed. After completion, under the action of the spring, the plug-in plate cooperates with the side opening, and the cover plate can be covered, which can be sealed to a certain extent and can absorb moisture inside the PT cabinet to increase the service life of components. The mounting block and the PT cabinet can be fixedly connected by bolts to prevent people from opening it by mistake. BRIEF DESCRIPTION OF THE DRAWINGS
