[0002] At present, 10KV box-type transformers are important power supply equipment in distribution network systems and are widely used in urban and rural areas. However, there are many common problems with existing 10KV box-type transformers. Existing 10KV box-type transformers are usually fixedly installed in distribution network lines and cannot be easily moved. This design makes it incapable of meeting temporary power supply needs. For example, temporary power supply is required in scenes such as construction sites, temporary activity venues, and emergency rescue sites, but the fixed 10KV box-type transformers cannot be quickly moved to the designated location, making it difficult to meet temporary power needs.

[0003] The installation and disassembly process of 10KV box-type transformers is complicated and requires professional operation, which consumes a lot of manpower and material resources. Especially in temporary power supply scenarios, frequent installation and disassembly will lead to a significant increase in costs, limiting its scope of application. In order to solve temporary power supply needs, it currently mainly relies on mobile power supply equipment such as power generators. However, the power supply of power generators is limited and the operating cost is high, making it difficult to meet the power demand of large-scale events, construction sites and other scenarios at any time.

[0004] Therefore, there is a need for a quick connection mechanism and a modular transformer cabinet that are easy to disassemble and assemble in a modular manner and can be flexibly moved and placed to meet the needs of the existing environment. Summary of the invention

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1 , this embodiment provides a quick connection mechanism.

[0029] The high-voltage connector 100 is made by precision casting. The head and tail of the high-voltage connector 100 are respectively set as an external terminal 101 and an internal terminal 102. The external terminal 101 is equipped with a lightning protection device that complies with the IEC 61000-4-5 standard, which enhances reliability in harsh environments. The internal terminal 102 adopts a spring contact structure to ensure reliable connection with the transformer in the cabinet, and the connection has low contact resistance and high stability.

[0030] The low voltage connector 200 is of plug-in design and is located opposite the high voltage connector 100. It is equipped with a circuit breaker MCB that complies with the IEC60947-7-1 standard as a safety module 201. The safety module 201 can quickly cut off the circuit in the event of overload, short circuit and leakage to protect the safety of personnel and equipment.

[0031] The connecting line 300 adopts a copper core cross-linked polyethylene insulated power cable that complies with the GB / T 3048.4-2014 standard. The cable has excellent electrical properties and mechanical strength, and can stably operate in a temperature range of -40°C to 125°C. The connecting line 300 connects the high-voltage connector 100 and the low-voltage connector 200 to the transformer in the cabinet. During actual operation, the staff can use the high-voltage connector 100 and the low-voltage connector 200 to connect the corresponding high-voltage equipment and low-voltage equipment outside the cabinet.

[0032] Example 2

[0033] Reference Figures 1 to 3 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0034] The transformer assembly 400 is an oil-immersed transformer. A high-voltage pile head 401 and a low-voltage pile head 402 are fixedly arranged on the top of the transformer assembly 400. Both the high-voltage pile head 401 and the low-voltage pile head 402 can be made of copper, aluminum or stainless steel, and must have good anti-oxidation performance. The high-voltage pile head 401 is connected to the internal connection end 102 through a high-voltage busbar 301. The connecting line 300 includes a high-voltage busbar 301 and a low-voltage busbar 302. The layout of the high-voltage busbar 301 and the low-voltage busbar 302 adopts a three-dimensional design. By optimizing the path, the cable length is reduced and the line impedance is reduced. In addition, the relative position between the busbars has been analyzed by electromagnetic compatibility EMC to ensure that there will be no mutual interference.

The interior of the shell is made of flame-retardant, high-temperature resistant insulating materials to ensure the safe operation of the equipment in complex environments. The docking module 501 includes a low-voltage docking unit 502 and a high-voltage docking unit 503, both of which are designed with quick connectors and comply with the IEC 61984 standard. The docking unit 502 and the high-voltage docking unit 503 are fixedly installed on the outer wall of the protective shell 500.

[0038] The external connection end 101 is fixedly arranged on the outside of the high-voltage docking unit 503, and the internal connection end 102 is fixedly arranged on the inside of the high-voltage docking unit 503, and is used to connect the inside and outside of the protective shell 500. The low-voltage docking unit 502 is also fixedly connected to the low-voltage connector 200. The debugging end face 502a is also arranged in the low-voltage docking unit 502 and is connected to the external environment. The staff can realize the rapid docking with the external low-voltage system through the debugging end face 502a.

[0039] The mobile terminal 500a is equipped with casters that meet the ISO 228-1 standard to ensure the stability and flexibility of the transformer cabinet during movement. The casters are made of hard rubber and have good wear resistance and shock absorption performance.
