[0002] The distribution cabinet is a general term for the motor control center. The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the distribution system.

[0003] Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0004] The current distribution cabinets have problems such as long construction period, inconvenient disassembly and maintenance during outdoor construction, and poor safety during use, which urgently requires research and development and improvement.

[0005] Therefore, based on the above problems, the present invention provides a high-safety power distribution cabinet with a detachable structure. Utility Model Content

[0027] One side of the circular insulating transition seat 107 is provided with a circular insulating transition seat screw groove 108 matched with the inner countersunk hole 104,

[0028] The square mounting seat 101 and the circular insulating transition seat 107 are fixed by the inner countersunk hole 104 and the circular insulating transition seat screw groove 108 through the insulating bolt 105,

[0029] The outer layer of the circular insulating transition seat 107 is provided with a guide through hole 114,

[0030] The other side of the circular insulating transition seat 107 is provided with a conductive plate 115,

[0031] One side of the conductive plate 115 is provided with a plurality of grounding piles 110,

[0032] One side of the conductive plate 115 is provided with a grounding wire 109.

[0033] The grounding wire 109 is sequentially inserted into the guide through hole 114 and the square mounting seat through hole 106 and protrudes from the power distribution cabinet 100.

[0034] The working principle is:

[0035] First, one end of the grounding wire 109 is inserted into the square mounting seat through hole 106 and led out of the power distribution cabinet 100, then the inner countersunk hole 104 and the circular insulating transition seat screw groove 108 are aligned one by one, and finally the square mounting seat 101 and the circular insulating transition seat 107 are tightened and fixed by the insulating bolt 105 (reverse operation when disassembling).

[0036] One end of the grounding wire 109 is connected to the lightning rod (the lightning rod is not marked in the figure, which does not affect the disclosure of the technical scheme of the application).

[0037] Example two

[0038] On the basis of the first embodiment, the high safety power distribution cabinet with convenient disassembly structure further comprises a prefabricated concrete seat 116, two groups of inner threaded sleeves 117 symmetrically arranged on one side of the prefabricated concrete seat 116, a limiting groove 118 arranged on one side of the prefabricated concrete seat 116 and located between the inner threaded sleeves 117, a grounding pile insulation guide sleeve 119 arranged on the other side of the prefabricated concrete seat 116 and used in cooperation with the limiting groove 118, and a fastening bolt 103 for fixing the square mounting seat 101 and the prefabricated concrete seat 116 through the outer countersunk head screw hole 102 and the inner threaded sleeve 117.

[0039] Among them, the circular insulation transition seat 107 and the conductive plate 115 are located in the limiting groove 118, and the grounding pile 110 is inserted into the grounding pile insulation guide sleeve 119 and protrudes from the prefabricated concrete seat 116.

[0040] The working principle is that the prefabricated concrete seat 116 is first hoisted to the corresponding excavated soil surface, then the outer countersunk head screw hole 102 and the inner threaded sleeve 117 are aligned one by one, and finally the square mounting seat 101 and the prefabricated concrete seat 116 are tightened and fixed by using the fastening bolt 103 (reverse operation can be performed during disassembly and maintenance).

[0041] Embodiment three

[0042] On the basis of the first embodiment or the second embodiment, the high safety power distribution cabinet with convenient disassembly structure further comprises a flexible insulation pad 111 arranged on the connecting surface of the square mounting seat 101 and the prefabricated concrete seat 116, a flexible insulation pad through slot 113 arranged in the center line of the flexible insulation pad 111, and two groups of fastening bolt through holes 112 arranged on the outer layer of the flexible insulation pad 111.

[0043] Among them, the circular insulation transition seat 107 and the conductive plate 115 are located in the flexible insulation pad through slot 113, and the fastening bolt 103 penetrates the fastening bolt through hole 112.

[0044] The flexible insulation pad 111 and the flexible insulation pad through slot 113 play the role of strengthening tightening during assembly, and also play the function of insulation and leakage prevention.

[0045] In addition, preferably, the circular insulation transition seat 107, the flexible insulation pad through slot 113, the conductive plate 115 and the limiting groove 118 are respectively arranged in circular structure or polygonal structure for matching use. When the polygonal structure is used for matching use, the corresponding anti-rotation misalignment before tightening is achieved, which facilitates assembly. When the circular structure is used for matching use, it is convenient for rapid alignment before tightening.
