Description

TECHNICAL FIELD

[0001] The utility model relates to power distribution equipment technical field, concretely relates to a compact european type box transformer. BACKGROUND

[0002] As a common power distribution equipment, the european type box transformer is widely used in urban power supply, industrial park and other fields, and is used for converting high-voltage electric energy into low-voltage electric energy and distributing to users.

[0003] For example, the prior device disclosed in Chinese patent authorization publication No. CN216672292U is a high-temperature-resistant european type box transformer. The short plate cooperates with the short shaft to rotate the one end of the limiting plate, so that the clamping block is turned out from the inside of the clamping groove. Then, the wires on the electrical elements are sequentially clamped in the inside of each group of arc-shaped grooves. Then, the limiting plate is rotated in the same way, so that the clamping block is clamped into the inside of the clamping groove. The position of each wire can be fixed between the limiting plate and the movable plate. Through the above operation, the staff can arrange and fix each wire, preventing the wires from being entangled with each other. However, in actual application, the internal space utilization of the prior device is relatively fixed. Only the related power distribution equipment can be placed horizontally, which leads to some deficiencies in space utilization, equipment layout and safety, and it is difficult to meet the requirements of large-capacity power supply and high safety at the same time in limited space. In addition, due to the unreasonable layout of the related power distribution equipment, the heat dissipation effect is poor, and maintenance is inconvenient. UTILITY MODEL CONTENTS

[0029] The layered placement assembly 3 includes a mounting frame 31 installed within the European-style transformer substation housing 2.

Through the layered placement assembly 3, the internal space of the European-style transformer substation housing 2 is efficiently utilized, improving the compactness and integration of the equipment, and facilitating installation, maintenance, and repair.

[0030] A high-voltage cabinet 4 is installed above the partition 36, and a transformer 5 is installed below the partition 36.

[0031] A low-voltage cabinet 6 is installed on the side of the mounting frame 31.

[0032] Furthermore, the partition 36 is made of non-conductive, fire-resistant, and heat-insulating materials, and possesses mechanical strength. The material selection of the partition 36 ensures the safety and reliability of the equipment, prevents electrical fires, and provides necessary mechanical support.

[0033] Furthermore, the high-voltage switchgear 4 is equipped with a high-voltage incoming terminal 41 and a high-voltage outgoing terminal 42, while the low-voltage switchgear 6 is equipped with a low-voltage incoming terminal 61 and a low-voltage main circuit breaker 62. The low-voltage switchgear 6 also includes a low-voltage compensation cabinet 63 and a low-voltage outgoing cabinet 64. This comprehensive configuration of the high-voltage switchgear 4 and the low-voltage switchgear 6 meets the needs of power control, protection, and monitoring, thereby improving power quality and utilization.

[0034] Furthermore, the high-voltage outgoing terminal 42, located away from the high-voltage cabinet 4, is connected to the transformer 5, and the low-voltage outgoing cabinet 64 is connected to the transformer 5. This clarifies the connection relationship between the high-voltage outgoing terminal 42 and the low-voltage outgoing cabinet 64 and the transformer 5, ensuring the normal transmission and conversion of electrical energy.

[0035] Furthermore, the layered placement component 3 also includes heat dissipation holes 33 formed in the mounting frame 31 for heat dissipation of the high-voltage switchgear 4, transformer 5, and low-voltage switchgear 6. The mounting frame 31 also has cable routing channels 34 for wiring. The design of the heat dissipation holes 33 and cable routing channels 34 improves the heat dissipation performance and wiring convenience of the equipment, ensuring the long-term stable operation of the equipment.

[0036] Furthermore, the European-style transformer substation housing 2 is equipped with an adjustable heat dissipation assembly 7 for heat dissipation. The adjustable heat dissipation assembly 7 includes a mounting frame 71 disposed within the European-style transformer substation housing 2, and a heat dissipation window 72 disposed within the mounting frame 71 for heat dissipation within the European-style transformer substation housing 2. The introduction of the adjustable heat dissipation assembly 7 enhances the heat dissipation capacity of the equipment, and the design of the heat dissipation window 72 facilitates air circulation and improves heat dissipation efficiency.

[0037] Furthermore, the heat dissipation adjustment assembly 7 also includes a mounting bracket 73 disposed within the European-style transformer substation housing 2. A connecting frame 74 is rotatably mounted within the mounting bracket 73, and at least four sets of electric cooling fans 75 are mounted within the connecting frame 74 for heat dissipation. A mounting base 76 is also provided at the top of the mounting bracket 73, and a drive motor 77 is disposed within the mounting base 76.

[0038] Example 2: Please refer to Figure 7 Furthermore, in conjunction with Embodiment 1, the European-style transformer substation housing 2 is further provided with a wiring channel 8 for power input and output, and a grounding wire 9 for grounding the high-voltage switchgear 4, transformer 5, and low-voltage switchgear 6. The design of the wiring channel 8 and the grounding wire 9 ensures the normal input and output of power and the safe grounding of the equipment, thereby improving the overall safety and reliability of the equipment.

[0039] In actual operation, firstly, the mounting frame 31 is installed into the European-style transformer substation housing 2, and its stability is ensured by reinforcing ribs 32. Next, according to the dimensions of the high-voltage switchgear 4 and the transformer 5, the partition 36 is slidably installed in different positions using the mounting rail 35 to flexibly adjust the vertical space.

[0040] After the space is divided, the high-voltage cabinet 4 is placed at the top of the partition 36, the transformer 5 is placed at the bottom of the partition 36, and the low-voltage cabinet 6 is installed next to the mounting frame 31 to maximize the use of space. The high-voltage cabinet 4 and the low-voltage cabinet 6 are connected by the wiring channel 8, and the cable tray 34 meets the internal wiring requirements.

[0041] High-voltage switchgear 4 is responsible for the control, protection, and monitoring of high-voltage electrical energy. The high-voltage input terminal 41 connects to an external high-voltage power supply for switching and control; the high-voltage output terminal 42 connects to transformer 5 for the protection and monitoring of the output high-voltage electrical energy. Transformer 5 converts the high-voltage electrical energy into low-voltage electrical energy for user consumption.

[0042] To ensure safety, the high-voltage switchgear 4, transformer 5, and low-voltage switchgear 6 are all grounded via grounding wire 9 to prevent leakage. Regarding the low-voltage switchgear 6, the low-voltage incoming terminal 61 receives low-voltage power to supply power to the low-voltage side electrical equipment; the low-voltage main circuit breaker 62 disconnects the circuit in case of short circuit or overload to protect the system; the low-voltage compensation cabinet 63 compensates for the power factor and improves power quality; and the low-voltage outgoing cabinet 64 distributes power to users.

[0043] The heat generated during equipment operation is dissipated normally through the heat dissipation window 72. During high-frequency use, the electric cooling fan 75 can be activated to enhance heat dissipation, and the airflow direction can be changed by rotating the connecting frame 74 through the drive motor 77: when facing each other, low-temperature air is blown in, and when facing away, high-temperature gas is extracted; the electric cooling fans 75 in the two sets of connecting frames 74 can also be arranged opposite each other, that is, the air outlet of the electric cooling fan 75 in one set of connecting frames 74 faces the European-style transformer housing 2, and the air outlet of the electric cooling fan 75 in the other set of connecting frames 74 faces away from the European-style transformer housing 2, so as to realize the connection of the air duct and meet different heat dissipation needs.

[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
