[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] like Figure 1-5 As shown, an assembled high and low voltage switchgear includes a high and low voltage switchgear 1, a waterproof unit 4, and heat dissipation vents 2. To prevent water from entering the high and low voltage switchgear 1, drainage units 3 are provided on both sides of the high and low voltage switchgear 1. To achieve heat dissipation inside the high and low voltage switchgear 1, heat dissipation vents 2 are provided horizontally through the drainage units 3. The heat dissipation vents 2 connect the inside and outside of the high and low voltage switchgear 1 to achieve heat dissipation inside the high and low voltage switchgear 1. The heat dissipation vents 2 are symmetrically distributed inside the high and low voltage switchgear 1 for heat dissipation. The waterproof unit 4 is inserted into the drainage unit 3 and is inserted to guide rainwater at the location of the heat dissipation vents 2.

[0023] Drainage unit 3 includes a third drain hole 33 opened inside the high and low voltage distribution cabinet 1, wherein, for example Figure 5 As shown, the length of the third drainage hole 33 is less than the total length of the waterproof unit 4, so that the waterproof unit 4 can still dissipate heat while waterproofing. The third drainage hole 33 is located on the outside of the high and low voltage distribution cabinet 1, and a first drainage hole 31 is provided. The first drainage hole 31 is used to abut against the bottom of the waterproof unit 4 inserted into the third drainage hole 33 for drainage. A second drainage hole 32 is provided on the side of the third drainage hole 33 away from the high and low voltage distribution cabinet 1. The second drainage hole 32 is used to insert the waterproof unit 4. The second drainage hole 32, the third drainage hole 33 and the first drainage hole 31 are interconnected. The side of the second drainage hole 32 away from the third drainage hole 33 extends to the outside of the high and low voltage distribution cabinet 1.

[0024] The lowest point of the first drain hole 31 and the lowest point of the third drain hole 33 are coplanar, and the highest point of the third drain hole 33 is higher than the highest point of the first drain hole 31. This is used for drainage operations to protect the electronic components inside the high and low voltage distribution cabinet 1 and prevent water accumulation inside the high and low voltage distribution cabinet 1 during use.

[0025] The waterproof unit 4 includes a waterproof inclined plate 41 inserted into the third drain hole 33. The waterproof inclined plate 41 is designed with an incline, tilting towards the first drain hole 31. During the rainy season, rainwater may splash into the ventilation hole 2. At this time, the waterproof inclined plate 41 will block the rainwater, and the rainwater will flow along the waterproof inclined plate 41 and the first drain hole 31 to the outside of the high and low voltage distribution cabinet 1. To prevent rainwater from accumulating in the third drain hole 33, and to prevent the water from accumulating in the third drain hole 33, the length of the waterproof inclined plate 41 is as follows: Figure 5 As shown, the length is shorter than that of the third drainage hole 33. At this time, the heat dissipation vent 2, the third drainage hole 33 and the high and low voltage distribution cabinet 1 are still connected, so that when the waterproof inclined plate 41 is waterproofing, the heat dissipation vent 2 can still dissipate heat.

[0026] In order to fix the position of the waterproof inclined plate 41, a sealing plate 42 is connected inside the waterproof inclined plate 41 located in the second drainage hole 32, and the sealing plate 42 is inserted into the second drainage hole 32.

[0027] To prevent the waterproof inclined plate 41 from falling off from the third drainage hole 33 during use, a rubber sealing ring 43 is connected between the sealing plate 42 and the waterproof inclined plate 41. The rubber sealing ring 43 is inserted into the third drainage hole 33, and the outer side of the rubber sealing ring 43 is in contact with the inner wall of the third drainage hole 33.

[0028] The rubber sealing ring 43 is made of rubber, which further increases the precision of the sealing plate 42 and the second drain hole 32.

[0029] The effect achieved by the entire embodiment is that during the rainy season, rainwater will splash into the heat dissipation vent 2. At this time, the waterproof slope 41 will block the rainwater, and the rainwater will flow along the waterproof slope 41 and the first drainage hole 31 to the outside of the high and low voltage distribution cabinet 1. In order to prevent rainwater from accumulating in the third drainage hole 33, and the length of the waterproof slope 41 is as follows: Figure 5 As shown, the length is shorter than that of the third drainage hole 33. At this time, the heat dissipation vent 2, the third drainage hole 33 and the high and low voltage distribution cabinet 1 are still connected, so that when the waterproof inclined plate 41 is waterproofing, the heat dissipation vent 2 can still dissipate heat. Example

[0030] like Figure 1-5 As shown, an assembled high and low voltage distribution cabinet 1 has a detachable and rotatable door 12 on its outer side. The detachable door 12 is used to enclose the high and low voltage distribution cabinet 1. When selecting a door, a door that is compatible with the model of the high and low voltage distribution cabinet 1 should be selected. The high and low voltage distribution cabinet 1 has a detachable cabinet mounting part 11 inside for installing its internal electronic components.

[0031] The overall effect of Embodiment 2 is that the input power is distributed to each branch via busbars (copper or aluminum) at the installation location 11 of the distribution cabinet, and the switching on and off is controlled by components such as circuit breakers and contactors, achieving flexible power distribution. Modular design: Each functional unit (such as incoming line, outgoing line, compensation, etc.) is independently assembled, which is convenient for expansion and maintenance, and it also has overload / short circuit protection: the fault current is cut off by circuit breakers (such as frame type, molded case type) or fuses. Leakage protection: the residual current device (RCD) monitors the leakage current. Voltage / current monitoring: the instruments and relays monitor the parameters in real time, and trigger alarms or tripping when abnormalities occur. Signal and automation integration: intelligent instruments, PLC or microcomputer protection devices are integrated to support remote monitoring (such as SCADA system) to achieve automated management, and then the assemblable door 12 and the high and low voltage distribution cabinet 1 are locked and closed.

[0032] Working Principle: When using this modular high and low voltage distribution cabinet, first check the integrity of each component. Input power is distributed to each branch via busbars (copper or aluminum) at position 11 of the cabinet mounting section. Circuit breakers, contactors, and other components control the switching on and off, achieving flexible power distribution. Modular Design: Each functional unit (such as incoming, outgoing, and compensation lines) is independently assembled, facilitating expansion and maintenance. It also features internal overload / short circuit protection: fault current is interrupted by circuit breakers (such as frame-type or molded case type) or fuses. Leakage Current Protection: Residual current device (RCD) monitors leakage current. Voltage / Current Monitoring: Instruments and relays monitor parameters in real time, triggering alarms or tripping in case of abnormalities. The signal and automation integration intelligent instrument, PLC or microcomputer protection device supports remote monitoring (such as SCADA system) to realize automated management. Then, the assemblable door 12 and the high and low voltage distribution cabinet 1 are locked and closed. Secondly, during the rainy season, rainwater will splash in at the heat dissipation vent 2. At this time, the waterproof slope 41 will block the rainwater. The rainwater will flow out of the high and low voltage distribution cabinet 1 along the waterproof slope 41 and the first drainage hole 31. In order to prevent rainwater from accumulating in the third drainage hole 33, and the length of the waterproof slope 41 is as follows: Figure 5 As shown, the length is shorter than that of the third drainage hole 33. At this time, the heat dissipation vent 2, the third drainage hole 33 and the high and low voltage distribution cabinet 1 are still connected, so that when the waterproof inclined plate 41 is waterproofing, the heat dissipation vent 2 can still dissipate heat, and finally complete the work of the assembled high and low voltage distribution cabinet.
