A front cover plate 2 is provided on one side of the cabinet 1, and a rear cover plate 3 is provided on the other side, wherein the rear cover plate 3 is arranged opposite to the front cover plate 2. A front handle 24 is provided on the front cover plate 2.

[0039] like Figure 3 and Figure 4 As shown, it also includes a cover interlocking assembly, and the cover interlocking assembly includes an interlocking rod 71, and the interlocking rod 71 is axially slidably connected to the cabinet 1. One end of the interlocking rod 71 is an operating end, and the other end is a locking end, wherein the operating end corresponds to the front cover 2, and the locking end corresponds to the rear cover 3. When the front cover 2 is connected to the cabinet 1, the front cover 2 squeezes the operating end, the locking end is in a locked position, and the rear cover 3 is prevented from being disassembled and assembled. The setting of the cover interlocking assembly can play a role in avoiding misoperation and can well protect the power supply of the main cable.

[0040] Specifically, the rear cover 3 and the cabinet 1 are connected in an up-and-down pull-out manner, and a locking hole corresponding to the locking end is provided on the rear cover 3. When the locking end is inserted into the locking hole, the up-and-down pull-out movement of the rear cover 3 relative to the cabinet 1 is hindered, thereby preventing the rear cover 3 from opening. However, after the interlocking rod 71 is withdrawn from the locking hole, the rear cover 3 can be normally withdrawn from the cabinet 1.

[0041] like Figure 4 As shown, specifically, the cover interlock assembly further includes a reset mechanism 72, the reset mechanism 72 includes a reset elastic member, and the interlock rod 71 is connected to the cabinet 1 via the reset elastic member. When the front cover 2 is connected to the cabinet 1, the reset elastic member stores energy; when the front cover 2 is separated from the cabinet 1, the reset elastic member drives the interlock rod 71 to slide axially and reset to the unlocked state.

[0042] like Figure 2 As shown, the power distribution component 6 includes a transformer connection unit 61 and an external connection unit, the external connection unit includes a main connector 62 and an emergency connector 63, the transformer connection unit 61 is connected to the voltage transformer 5, the emergency connector 63 is arranged toward the front cover plate 2, and the main connector 62 is arranged corresponding to the rear cover plate 3.

The wiring position of the main cable corresponds to the rear cover 3, and the rear cover 3 can be opened to operate the main cable.

[0044] like Figure 5-Figure 8 As shown, the front cover plate 2 is provided with an emergency operation channel 21 communicating with the installation cavity. An emergency operation panel 4 is also included, which corresponds to the emergency operation channel 21 and is detachably connected to the front cover plate 2.

[0045] like Fig.11 As shown, the emergency operation panel 4 is provided with an emergency cable channel 46, and the emergency cable channel 46 corresponds to the emergency connector 63. The emergency operation panel 4 is provided with a movable cover plate 44, and the movable cover plate 44 corresponds to the emergency cable channel 46 and is used to control the opening and closing of the emergency cable channel 46.

[0046] When the power grid is normal, the voltage transformer draws power from the grid through the transformer connection unit 61 and the main connector 62. When the power grid fails, an external power supply is connected to the emergency connector 63, and the voltage transformer draws power through the emergency connector 63 and the transformer connection unit 61.

[0047] When the power grid fails and emergency power is needed, the staff can remove the emergency operation panel 4 and perform the wiring operation of the emergency cable through the emergency operation channel 21 without opening the front panel, which is convenient for operation. Since the emergency operation panel 4 is provided with an emergency cable channel 46 for the emergency cable to pass through, after completing the wiring operation of the emergency cable, the emergency operation panel 4 can be connected to the front panel to close the emergency operation channel 21, which plays a good protective role for the internal equipment. When the power grid is powered normally, the movable cover 44 can close the emergency cable channel 46 to further improve the protection effect.

[0048] like Figure 9-11 As shown, further, a compression elastic member 41 is provided between the movable cover plate 44 and the emergency operation panel 4. Under normal conditions, the movable cover plate 44 closes the emergency cable channel 46 under the elastic force of the compression elastic member 41. Specifically, a limiting pressure plate 42 is provided on the inner side of the front cover plate 2, and the limiting pressure plate 42 is located on the upper side of the emergency cable channel 46. A sliding channel is formed between the limiting pressure plate 42 and the front plate, and the movable cover plate 44 is slidably arranged in the sliding channel.

[0049] like Fig.10 and Fig.11 As shown, the limiting pressure plate 42 is provided with a limiting column 45, one end of the pressing elastic member 41 is connected to the limiting column 45, and the other end is connected to the movable cover plate 44. The movable cover plate 44 is also provided with a long limiting hole 43, and the limiting column 45 is arranged through the limiting hole 43.

[0050] like Figure 8-Figure 11 As shown, further, a mounting platform 22 is provided inside the emergency operation panel 4, and the mounting platform 22 is not higher than the lower edge of the emergency operation channel 21. Specifically, the front cover 2 is partially bent inward to form the mounting platform 22. An emergency cable clamp 23 is provided on the mounting platform 22, and the emergency cable clamp 23 is aligned with the emergency cable channel 46.

[0051] like Figure 6 As shown, specifically, both sides of the emergency operation channel 21 are provided with slide grooves 25 extending in the vertical direction, and the emergency operation panel 4 is slidably connected to the front cover plate 2 through the slide grooves 25. The emergency cable channel 46 extends downward to the lower edge of the emergency operation panel 4.

[0052] After the emergency cable 8 is connected, the emergency operation panel 4 is inserted into the slide groove from top to bottom, and the movable cover 44 automatically overcomes the elastic force under the obstruction of the emergency cable 8 and opens without manual opening of the movable cover 44. Correspondingly, when the emergency operation panel 4 is removed, the movable cover 44 will automatically close under the elastic force.

[0053] The voltage transformer cabinet of the present application can quickly complete emergency power supply operation when a power supply line fails, and has the advantages of safety, reliability and convenient operation.

[0054] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
