Referring to fig. 1 and 2, an embodiment of the present invention provides an electrical apparatus 100, which mainly includes a frame 10, a drawing structure 20, and an electrical module installed on the drawing structure 20. The drawing structure 20 is a drawer structure, so as to drive the electrical module thereon to enter and exit the frame 10, thereby facilitating various operations and maintenance of the electrical module on the drawing structure 20 by an operator.

As shown in fig. 2 and 3, the frame 10 defines a plug space 11, and the plug space 11 has an opening 12; the opening 12 may be located on the front side of the electrical apparatus 100 to facilitate operation by an operator. The frame 10 may include an upper cover 14, left and right side plates 15 and 16 connected to both sides of the upper cover 14, a bottom side plate 17 connected to the left and right side plates 15 and 16 and facing the upper cover 14, and may further include a rear side plate 18 facing the opening 12. These upper cover 14, left side plate 15, right side plate 16, bottom side plate 17 and rear side plate 18 may enclose the insertion space 11; note that the upper cover 14, the left side plate 15, the right side plate 16, the bottom side plate 17, and the rear side plate 18 are not necessarily limited to a complete flat plate-like structure, and may be substantially plate-shaped; for example, one or more of the top cover 14, left side panel 15, right side panel 16, bottom side panel 17, and rear side panel 18 may be perforated to allow for the installation of associated components or for the passage of wires. The left side plate 15, the right side plate 16 and the bottom side plate 17 can be used as a structure for guiding the movement of the drawing structure 20, and pulleys can be arranged on the left side plate 15 and the right side plate 16 to support the drawing structure 20 by the pulleys, so that the movement resistance is reduced.

As shown in fig. 2 and 3, the drawing structure 20 has a panel 21 disposed on a side away from the rear side plate 18. And electrical modules such as a circuit breaker 31 and a lightning arrester 32 are mounted on the drawing structure 20. For example, the circuit breaker 31 may be an air switch, and further may be a photovoltaic incoming air switch; the air switch (english name CB) may also be called an air circuit breaker, which is a type of circuit breaker that automatically opens whenever the current in the circuit exceeds the rated current. The pulling structure 20 is configured to be inserted into and engaged with the insertion space 11, that is, the pulling structure 20 can be inserted into the insertion space 11 and can be pulled and moved between a first position and a second position relative to the frame 10.

In the first position, as shown in fig. 1 and 2, the drawer structure 20 and the circuit breaker 31 and the lightning protector 32 thereon are located in the insertion space 11 and the panel 21 covers the opening 12. The drawing structure 20, the circuit breaker 31 and the lightning protector 32 thereon are inserted into the plugging space 11, so that the electrical equipment is assembled for use.

Referring to fig. 3 and 4, in the second position, a portion of the pull-out structure 20 is pulled out of the insertion space 11, so that the panel 21 is away from the opening 12, and the circuit breaker 31 and the lightning protector 32 are taken out of the frame 10 by the pull-out structure 20. By pulling out a part of the drawer structure 20 from the insertion space 11, it is possible to perform operations such as inspection, maintenance, replacement, etc. of the electrical module, such as the circuit breaker 31 and the lightning protector 32, on the drawer structure 20. In order to prevent the pulling structure 20 from being separated from the inserting and pulling space 11, a limiting structure may be disposed between the pulling structure 20 and the frame 10, so as to prevent the pulling structure 20 from continuously moving and falling off from the frame 10 when the pulling structure moves to the second position.

Thus, in the above embodiment, the drawing structure 20 is inserted into and engaged with the insertion and extraction space 11, and the drawing structure 20 is arranged to be capable of drawing and moving between the first position and the second position relative to the frame 10, so that the drawing structure 20 and the electrical modules thereon, such as the circuit breaker 31 and the lightning arrester 32, can be drawn out from the frame 10, and the electrical modules can be conveniently checked, maintained, replaced and the like by an operator.

In further embodiments, as shown in connection with fig. 2 and 3, the circuit breaker 31 is mounted to the panel 21 and the lightning protector 32 is located within the interior space 22 of the drawer structure 20.

Of course, the positions of the terminal 34, the breaker 31 and the lightning arrester 32 in the drawer structure 20 can be adjusted to each other, for example, the lightning arrester 32 can be installed to the left or to the right.

In further some embodiments, as shown in fig. 2, the frame 10 has a wire inlet 13 on one side of the panel 21, the frame 10 has a voltage stabilizing module 35 on the other side of the panel 21, and the lightning protector 32 is connected to the voltage stabilizing module 35 by a third wire 43. For example, the wire inlet 13 may be opened on the left side plate 15 near the panel 21, that is, near the front of the electric device 100, to introduce wires from the front side. The voltage stabilizing module 35 may be disposed inside the right side plate 16, and may be used to convert an input voltage into a stable voltage for output. In addition, an intermediate side plate 19 may be further provided on a side of the voltage stabilizing module 35 away from the right side plate 16, so that a space for accommodating the voltage stabilizing module 35 is formed between the right side plate 16 and the intermediate side plate 19, and a space for accommodating the drawing structure 20 is directly formed between the left side plate 15 and the intermediate side plate 19.

For example, the voltage stabilization module 35 may be a photovoltaic module for converting a photovoltaic input voltage into a stabilized direct current voltage.

It can be understood that the arrangement positions of the wire inlet 13 and the voltage stabilizing module 35 can be interchanged, that is, the wire inlet 13 is arranged on the right side plate 16, and the voltage stabilizing module 35 is arranged on the inner side of the left side plate 15.

In further embodiments, as shown in fig. 2 and 3, the panel 21 is provided with a screw 23, and the screw 23 is used for detachably connecting to the frame 10. For example, the frame 10 may be provided with a threaded hole 141 on the structure near the opening 12 for screwing a screw 23 into, thereby fixing the drawing structure 20 on the frame 10. The screw hole 141 may be installed or formed at the front end of the upper cover 14. In addition, the screw 23 can be movably connected to the panel 21 to form a release screw.

In some embodiments, the electrical device 100 may be an embedded power supply device. For example, as shown in fig. 1 to 3, the electrical device 100 may be integrally embedded in a related structure of the case and may be fastened to the related structure by the connection member 50. The connector 50 may be mounted on the left and right side panels 15 and 16. The electric device 100 functions as a power supply device to output a stable direct current.
