Description

Technical Field

[0001] This utility model relates to the field of transformer cabinet technology, and in particular to a transformer cabinet with a protective structure. Background Technology

[0002] A substation is a device used in a power system to transmit, distribute, convert, and control electrical energy. Substations are mainly used in substations, distribution stations, industrial and mining enterprises, etc., to distribute, convert, and control electrical energy, ensuring the normal operation of the power system. Substations also have the function of protecting electrical energy, and can detect faults and abnormalities in the power system and take corresponding protective measures to ensure the safe operation of the power system.

[0003] For example, Chinese patent application number 201921295631.5 discloses a moisture-proof substation, including a substation body. The bottom of the substation body has a mounting groove, and a sliding seat is movably connected within the mounting groove. The sliding seat is mounted on the edge of a base plate. A first drain hole is provided on the base plate, and a base is provided on the underside of the base plate. A second drain hole is provided on the base, and a filter screen is fixedly connected within the second drain hole. The lower end of the second drain hole communicates with a water storage cavity, and a plug is movably connected to the end of the water outlet pipe. This moisture-proof substation utilizes the coordinated operation of the substation body, base plate, second drain hole, water storage cavity, anti-clogging cavity, heating chamber, fan, and heating pipe. The base plate collects accumulated water inside the substation body through the first drain hole, while the heating chamber, through the interaction of the fan and heating pipe, generates high-temperature gas to dry the interior of the substation body, improving the moisture-proof effect.

[0004] However, while the aforementioned substation cabinets improve moisture resistance during use, they cannot protect against certain mechanical damage, such as bites from small animals, when placed outdoors, as the outer side of the heat dissipation mesh lacks protection. Therefore, those skilled in the art have provided a substation cabinet with a protective structure to address the problems mentioned in the background section. Utility Model Content

[0036] Reference Figures 1-4 The present invention provides a transformer cabinet with a protective structure, comprising a transformer cabinet body 1, a fixed base 2 fixed at the bottom of the transformer cabinet body 1, a movable cabinet door 3 rotatably connected to the outside of the transformer cabinet body 1 via a rotating shaft, a top baffle 4 fixed at the top of the transformer cabinet body 1, a heat dissipation mesh plate mounting sleeve 5 fixed to the outside of the transformer cabinet body 1, a heat dissipation mesh plate body 6 movably inserted into one side of the heat dissipation mesh plate mounting sleeve 5, a stable mounting mechanism 7 provided on the outside of the transformer cabinet body 1, and a protective mechanism 8 fixed on the outside of the transformer cabinet body 1.

[0037] The protective mechanism 8 includes a mounting bracket 81. Multiple protective connecting posts 82 are fixed to the outer side of the mounting bracket 81. A lower mounting post 83 is fixed to the bottom of the mounting bracket 81. A lower fixing frame 84 is fixed to the outer side of the substation cabinet 1. An upper mounting post 85 is fixed to the top of the mounting bracket 81. An upper fixing frame 86 is fixed to the outer side of the substation cabinet 1. A metal gear 87 is fixed to the outer side of the upper mounting post 85. A metal rack 88 meshes with the outer side of the metal gear 87. A mounting pad 89 is fixed to the outer side of the metal rack 88. An anti-detachment slider 810 is fixed to the bottom of the mounting pad 89. When the anti-detachment slider 810 moves, it can drive the mounting pad 89 and the metal rack 88 to move simultaneously. The upper fixing frame 86... The upper fixing frame 86 has a sliding groove, and an anti-disengagement slider 810 is slidably connected to the upper fixing frame 86 through the sliding groove. A connecting pad 811 is fixed to the outside of the anti-disengagement slider 810, and a positioning threaded sleeve 812 is fixed to the outside of the connecting pad 811. A positioning threaded post 813 is threaded to one side of the positioning threaded sleeve 812 and passes through the other side, so that the positioning threaded post 813 can engage with the positioning threaded sleeve 812. A positioning hole is provided inside the upper fixing frame 86. The size of the positioning hole is adapted to the size of the positioning threaded post 813. After the positioning threaded post 813 engages with the positioning threaded sleeve 812 and one end of the positioning threaded post 813 is movably inserted into the positioning hole, the position of the connecting pad 811 can be fixed.

[0038] The stable installation mechanism 7 includes a lifting baffle 71, with an anti-detachment lifting slider 72 fixed at the bottom of the lifting baffle 71 and a movable sleeve 73 fixed at the top of the lifting baffle 71. A cast iron threaded rod 74 is fixed on one side of the heat dissipation mesh plate body 6, with a metal baffle 75 fixed at one end of the cast iron threaded rod 74. A washer 76 is movably sleeved on the outside of the cast iron threaded rod 74, and a metal nut 77 is threadedly connected to the outside of the cast iron threaded rod 74. A groove is provided inside the movable sleeve 73, the size of which is adapted to the size of the cast iron threaded rod 74, allowing the movable sleeve 73 to be movably sleeved on the outside of the cast iron threaded rod 74. The transformer cabinet 1 is slidably connected to the anti-detachment lifting slider 72 via a slide groove. The outside of the metal nut 77 is provided with anti-slip texture to facilitate the user's rotation of the metal nut 77.

[0039] Working principle: When the substation cabinet 1 is in operation, the heat dissipation mesh plate body 6 is inserted into the heat dissipation mesh plate mounting sleeve 5, which serves to filter particulate dust. At the same time, when the substation cabinet 1 is placed outdoors, the anti-disengagement slider 810 can be moved to move the mounting pad 89 and the metal rack 88, so that the metal gear 87 drives the upper mounting column 85 and the mounting bracket 81 to rotate. This allows the outer protective connecting column 82 of the mounting bracket 81 to protect the filter screen of the heat dissipation mesh plate body 6. At this time, the positioning threaded column 813 and the positioning threaded sleeve 812 are threadedly connected, and one end of the positioning threaded column 813 is movably inserted into the mounting bracket 81. This allows for easy locking of the protective connecting column 82 at an angle, ensuring stable protection of the heat dissipation mesh plate body 6 by the protective connecting column 82. When the heat dissipation mesh plate body 6 needs to be replaced, the metal nut 77 can be rotated to move the corresponding surface of the metal nut 77 away from the washer 76, and then the lifting baffle 71 can be pushed down. The lifting baffle 71 will drive the anti-disengagement lifting slider 72 and the moving sleeve 73 to move. After the moving sleeve 73 is released from blocking and locking the heat dissipation mesh plate body 6, the heat dissipation mesh plate body 6 can be pulled out from the heat dissipation mesh plate mounting sleeve 5 and a new heat dissipation mesh plate body 6 can be replaced, thus achieving the purpose of easy maintenance and replacement of the heat dissipation mesh plate body 6.
