[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1, as Figures 1 to 7 As shown, this embodiment 1 provides a photovoltaic power generation control cabinet with a leakage protection function, including: a cabinet 1, a wire taking-up device 2 and a circuit breaker device; the wire taking-up device 2 is arranged in the cabinet 1, and the wire taking-up device 2 is suitable for winding up the grounding wire in the cabinet 1; the circuit breaker device is arranged in the cabinet 1, and the circuit breaker device is respectively connected to the socket box 5 and the control device, and the circuit breaker device is suitable for disconnecting from the socket box 5 and / or the control device; the winding of the grounding wire is realized, the grounding wire is prevented from swinging during the closing process of the cabinet door 11, and the grounding wire is prevented from being squeezed and damaged by the cabinet door 11, and leakage protection is performed at the same time.

[0026] In this embodiment, the circuit breaker device includes: a control device circuit breaker 3 and a socket box circuit breaker 4; the control device circuit breaker 3 is connected to the control device; the socket box circuit breaker 4 is connected to the socket box 5; the control device circuit breaker 3 is suitable for disconnecting from the control device; the socket box circuit breaker 4 is suitable for disconnecting from the socket box 5; the circuit breakers in the socket box circuit breaker 4 correspond to the sockets in the socket box 5 one by one, and the circuit breakers are connected to the corresponding sockets; the circuit breaker is suitable for disconnecting the corresponding sockets; in specific use, the load can be connected to the socket box 5 or directly connected to the control device. When the load is connected to the socket box 5, when the socket box 5 leaks, the circuit breaker corresponding to the socket box 5 can be disconnected for protection and the control device circuit breaker 3 can be disconnected synchronously. When the load is directly connected, if the load leaks, the load is disconnected by the control device circuit breaker 3; the leakage protection value of each circuit breaker of the socket box 5 is 0.03A, The leakage value and time of the control device circuit breaker 3 are set to 0.1A and 1S. When there is a leakage condition, the relay drives the control device circuit breaker 3 to trip; when a leakage condition occurs when using the socket box 5, the circuit breaker of the socket box 5 will be disconnected first. Since the leakage current set for the control device circuit breaker 3 is large and the delay time is long, false operation can be avoided to interfere with diagnosis and maintenance; in addition, when only the control device circuit breaker 3 is used without the socket box 5, due to the protection of the leakage relay, the control device circuit breaker 3 can also perform protective action when a leakage condition occurs.

[0027] In this embodiment, the wire-taking device 2 includes: a wire-taking mechanism and a pair of wiring mechanisms; one of the wiring mechanisms is arranged on the inner wall of the cabinet 1, and the other wiring mechanism is arranged on the side of the cabinet door 11 on the cabinet 1 facing the inside of the cabinet 1; the wire-taking mechanism is arranged between the two wiring mechanisms; the space between the two wiring mechanisms is suitable for connecting the grounding wire; the wire-taking mechanism is suitable for winding up the grounding wire; one end of the grounding wire is connected to one wiring mechanism, and the other end is connected to the other wiring mechanism. At the same time, the grounding wire passes through the wire-taking mechanism, and the wire-taking mechanism can wind up the excess grounding wire to prevent the grounding wire from swinging off at any time; because the cabinet door 11 of the cabinet 1 needs to be opened, the length of the grounding wire between the two wiring mechanisms is relatively long in the traditional case, and it is necessary to meet the requirement that the grounding wire is connected to the two wiring mechanisms at the same time when the cabinet door 11 is opened to the maximum position, which will cause the grounding wire to swing off when the cabinet door 11 is closed, and the swinging part may be squeezed and damaged by the cabinet door 11.

[0028] In this embodiment, the wiring mechanism includes: a base 21 and a copper nose 211; the base 21 is arranged on the corresponding inner wall of the cabinet 1 or on the side of the cabinet door 11 on the cabinet 1 facing the inside of the cabinet 1; the copper nose 211 is arranged on the base 21; the copper nose 211 is inclined toward the corresponding inner wall of the cabinet 1 and the side of the cabinet door 11 on the cabinet 1 facing the inside of the cabinet 1; both ends of the grounding wire are removed into the corresponding copper nose 211; the copper nose 211 can clamp the grounding wire to maintain the connection of the grounding wire and prevent the grounding wire from falling off; in the traditional case, repeated opening of the cabinet door 11 may cause the grounding wire and the copper nose 211 to fall off; by tilting the copper nose 211, when the cabinet door 11 is closed, the copper nose 211 can be inserted into the outer through hole 234 of the outer sleeve 23, and the outer through hole 234 clamps the copper nose 211, so that the copper nose 211 can maintain the clamping of the grounding wire to prevent the grounding wire from falling off, In this embodiment, the wire-winding mechanism includes: an inner sleeve 22 and an outer sleeve 23; the inner sleeve 22 is arranged on the inner bottom surface of the outer sleeve 23; a volute spring 232 is arranged between the inner sleeve 22 and the outer sleeve 23; the grounding wire passes through the inner sleeve 22 and the outer sleeve 23; the volute spring 232 drives the rotation of the inner sleeve 22, so that the excess grounding wire can be wound on the inner sleeve 22 to prevent the grounding wire from swinging.

[0029] In this embodiment, a column 221 is provided on the bottom surface of the inner sleeve 22; a first limiting ring 222 is provided on the bottom surface of the inner sleeve 22, and the first limiting ring 222 is arranged around the column 221; an annular groove 223 is provided on the surface of the first limiting ring 222 facing the column 221, and the annular groove 223 is close to the bottom surface of the inner sleeve 22; a pair of inner through holes 224 are provided on the side wall of the inner sleeve 22, and the inner through holes 224 are suitable for passing through the grounding The inner sleeve 22 is provided with a handle 225 on its top surface; the outer sleeve 23 is provided with a second limiting ring 231 on its inner bottom surface, the column 221 is provided in the area surrounded by the second limiting ring 231; the volute spring 232 is provided between the column 221 and the second limiting ring 231; one end of the volute spring 232 is connected to the column 221, and the other end is connected to the second limiting ring 231; a ring member 23 is provided on the outer wall of the second limiting ring 231 3. The annular member 233 is arranged in the annular groove 223. Through the cooperation between the annular member 233 and the annular groove 223, the inner sleeve 22 and the outer sleeve 23 can rotate and prevent the inner sleeve 22 and the outer sleeve 23 from falling off; a clamping block can be arranged on the volute spring 232, and a clamping groove can be arranged on the column 221 and the second limiting ring 231. The clamping block can be arranged in the clamping groove, so that the volute spring 232 is connected with the column 221 and the second limiting ring 231; the outer A pair of outer through holes 234 are provided on the side wall of the tube 23, and the outer through holes 234 correspond to the inner through holes 224; the grounding wire passes through the outer through hole 234; the grounding wire passes through the inner through hole 224 and the outer through hole 234; in the traditional case, when closing the cabinet door 11, it is necessary to lift the fallen grounding wire, which will cause the copper nose 211 to receive the rotational force and make the copper nose 211 loose, so the grounding wire is rolled up by the wire-winding mechanism to avoid lifting the grounding wire and prevent the copper nose 211 from loosening.

[0030] In the present embodiment, the diameter of the outer through hole 234 is smaller in the middle and larger at both ends; a chamfer is provided in the middle of the outer through hole 234; since the diameter of the outer through hole 234 is larger at both ends and smaller in the middle, the middle of the outer through hole 234 may be an edge, and the edge may cause damage to the grounding wire, so the edge is changed to a chamfer to avoid damage to the grounding wire; the shape of the outer through hole 234 can facilitate the insertion of one end of the copper nose 211, and when the cabinet door 11 is closed, the copper nose 211 is inserted into the corresponding outer through hole 234, and the copper nose 211 is clamped by the outer through hole 234, thereby clamping the copper nose 211 to the grounding wire.

[0031] In this embodiment, the inner sleeve 22 is rotated to allow the volute spring 232 to be wound. At this time, the grounding wire is passed through the inner through hole 224 and the outer through hole 234. The two ends of the grounding wire are connected to the corresponding copper noses 211. After the grounding wire passes through, the grounding wire is wound on the inner sleeve 22 by resetting the volute spring 232. The wire-winding mechanism is in the middle position between the two copper noses 211. When the cabinet door 11 is opened, the wound grounding wire can be unwound to meet the required length of the grounding wire between the two copper noses 211 after the cabinet door 11 is opened. The middle position can facilitate the winding and unwinding of the grounding wire. When the cabinet door 11 is closed, the grounding wire is automatically wound inside by the volute spring 232. On the sleeve 22, it is prevented from manually lifting the fallen grounding wire and preventing the copper nose 211 from loosening during the process of lifting the grounding wire. When the cabinet door 11 is closed, the copper nose 211 extends into the corresponding external through hole 234 to keep the grounding wire clamped and prevent it from falling off. Under traditional circumstances, the operator may forget to close the cabinet door 11 after opening the cabinet door 11 for maintenance and other operations. Therefore, the volute spring 232 can keep the cabinet door 11 with a tendency to close. The operator needs to keep the cabinet door 11 open while working, and close the cabinet door 11 when the volute spring 232 automatically reels the grounding wire after the operation is completed, to avoid forgetting to close the cabinet door 11.
