[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0021] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.
[0022] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.
[0023] Embodiment 1 of the floor-standing combined transformer provided by the utility model:
[0024] like Figures 1 to 4 As shown,
[0025] The utility model comprises a transformer housing 1 and a transformer coil arranged in the transformer housing 1, a radiator 11 is arranged on the side of the transformer housing 1, a switch room 2 is detachably arranged on the top of the transformer housing 1, a linkage switch 21 is arranged in the switch room 2, a fan frame 22 is arranged on the bottom side of the switch room 2, a heat dissipation fan 23 is arranged on the fan frame 22, a heat dissipation through hole 201 is arranged on the side wall of the switch room 2, and the heat dissipation fan 23 is used for ventilation and heat dissipation of the switch room 2 and accelerated heat dissipation of the transformer housing 1.
[0026] Among them, the transformer housing 1, the linkage switch 21 for controlling high and low voltages, and the heat dissipation fan 23 are integrated, making the overall structure of the transformer more compact and occupying a small area, suitable for various occasions with limited space. In addition, the heat dissipation efficiency of the overall structure is improved, ensuring the stable operation of the overall transformer.
[0027] It should be noted that the linkage switch 21 can specifically adopt the switch structure disclosed in patent application number CN2024106325689, so the specific structure will not be repeated here.
[0028] In this embodiment, the fan rack 22 includes an inclined panel 221 for installing a heat dissipation fan 23, and triangular plates 222 are provided at both ends of the inclined panel 221. The inclined panel 221 and the triangular plate 222 are both removable and arranged in the switch room 2. An intermediate chamber 223 is formed between the inclined panel 221, the triangular plate 222, and the bottom surface and side walls of the switch room 2, and the intermediate chamber 223 is connected to the outside.
[0029] Wherein, the side edges of the fan frame 22 are provided with side wings 224 for connecting with the bottom surface and side walls of the switch room 2 .
[0030] The detachable connection through the side wings 224 and bolts makes it easier to install and replace the heat dissipation fan 23, and also facilitates the cleaning and maintenance of the fan frame 22 and the inside of the switch room 2.
[0031] In addition, the fan rack 22 has a stable structural design, which ensures that the fan rack will not shake or move when the heat dissipation fan 23 is running, thereby ensuring the stability and reliability of the entire system.
[0032] The wind rack 22 includes a group of symmetrically arranged wind racks.
[0033] Two inclined panels 221 for fixing the heat dissipation fan 23 are arranged opposite to each other, so that the airflow distribution of the heat dissipation fan 23 is more uniform, avoiding local overheating caused by uneven airflow, and also improving the balance and stability of the entire system.
[0034] In this embodiment, a notch 225 is provided on the bottom surface of the intermediate chamber 223 , and the notch 225 is located above the corresponding heat sink 11 in the air.
[0035] During specific use, the gas in the switch room 2 is drawn out through the heat dissipation fan 23 and the external air enters through the heat dissipation through hole 201, so as to achieve heat dissipation of the switch room 2. The heat dissipation in the switch room 2 helps to dissipate the heat on the top of the transformer housing 1, and accelerates the heating and heat dissipation of the transformer housing 1. In addition, since the temperature increase in the switch room 2 is conducted by the heat dissipation of the transformer housing 1 itself, the temperature in the switch room 2 is lower than the temperature of the transformer housing 1 itself, and the air drawn out of the switch room 2 is blown out from the slot 225 and blown onto the corresponding radiator 11, so as to accelerate the heat dissipation of the radiator 11.
[0036] It should be noted that, when only the heat dissipation fan 23 is needed to assist the heat dissipation of the radiator 11 , the heat dissipation fan 23 can also be enabled to blow air through the slot 225 to dissipate heat.
[0037] In this embodiment, the linkage switch 21 includes a high-voltage switching protection switch on one side and a low-voltage load isolating switch on the other side. A cable sheath 24 corresponding to the high-voltage switching protection switch and the low-voltage load isolating switch is provided on one side of the bottom end of the switch chamber 2, and the top end of the cable sheath 24 is connected to the inside of the switch chamber 2.
[0038] The cable casing 24 is sealed in cooperation with the switch room 2, and the grounded cable extends out through the cable casing 24, which protects the cable on the one hand and improves the safety of the overall structure on the other hand.
[0039] In this embodiment, a bracket 25 for supporting the linkage switch 21 is provided in the switch chamber 2. The linkage switch 21 is provided at the top of the bracket 25. The height of the bracket 25 is 40 cm.
[0040] The linkage switch 21 is supported by a bracket 25 having a certain height, so that a distance is generated between the linkage switch 21 and the bottom surface of the switch chamber 2, and an air gap is formed to avoid direct heat transfer and prevent failure or performance degradation caused by overheating.
[0041] According to the above description of this specification, those skilled in the art may also understand that the terms used below, such as "up", "down", "front", "back", "left", "right", "width", "horizontal", "top", "bottom", "inside", "outside" and other terms indicating orientation or position relationship are based on the orientation or position relationship shown in the drawings of this specification, which are only for the purpose of facilitating the explanation of the scheme of the utility model and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in a specific orientation. Therefore, the above-mentioned orientation or position relationship terms cannot be understood or interpreted as limitations on the scheme of the utility model.
