DETAILED DESCRIPTION
[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0022] Please refer to Figures 1 to 4 The embodiment of the utility model provides a box-type substation 100 for performing power transformation operations. It can shorten the length of the connecting bus 130 while ensuring the power transformation effect, avoid resource waste, and save material costs.
[0023] The box-type substation 100 includes an outlet cabinet 110, a capacitor cabinet 120 and a connecting bus 130. The outlet cabinet 110 and the capacitor cabinet 120 are arranged side by side and connected to each other for easy installation and fixation, and for easy conduction between the outlet cabinet 110 and the capacitor cabinet 120. The outlet cabinet 110 is provided with a main current bus 111, the capacitor cabinet 120 is provided with a circuit breaker 121, and the connecting bus 130 is connected between the main current bus 111 and the circuit breaker 121 to achieve conduction between the main current bus 111 and the circuit breaker 121. The connecting bus 130 is arranged between the outlet cabinet 110 and the capacitor cabinet 120, and the connecting bus 130 is relatively provided with a first end 131 and a second end 132; the first end 131 is connected to the main flow bar 111 to achieve conduction between the connecting bus 130 and the main flow bar 111; the second end 132 is connected to the circuit breaker 121 to achieve conduction between the connecting bus 130 and the circuit breaker 121.
[0024] Specifically, a first end wall 112 is provided on the side of the outgoing line cabinet 110 away from the capacitor cabinet 120, and the first end 131 is spaced apart from the first end wall 112, that is, part of the connecting bus 130 located in the outgoing line cabinet 110 is not arranged through the outgoing line cabinet 110, and there is a certain distance between the end of the connecting bus 130 away from the capacitor cabinet 120 and the first end wall 112. Compared with the technical solution in the prior art that the horizontal bus is arranged through the switch cabinet, the length of the connecting bus 130 can be effectively shortened without affecting the conduction effect between the connecting bus 130 and the main current bus 111, thereby avoiding waste of resources, saving material costs, and ensuring the power transformation effect.
[0025] Correspondingly, a second end wall 122 is provided on the side of the capacitor cabinet 120 away from the outlet cabinet 110, and the second end 132 is spaced apart from the second end wall 122, that is, part of the connecting bus 130 located in the capacitor cabinet 120 is not arranged through the capacitor cabinet 120, and there is a certain distance between the end of the connecting bus 130 away from the outlet cabinet 110 and the second end wall 122. Compared with the technical solution in the prior art that the horizontal bus is arranged through the switch cabinet, the length of the connecting bus 130 can be effectively shortened without affecting the conduction effect of the connecting bus 130 and the circuit breaker 121, thereby avoiding waste of resources, saving material costs, and ensuring the power transformation effect.
[0026] In this embodiment, the box-type substation 100 is placed on a horizontal plane, and the connecting busbar 130 is extended in the horizontal direction to pass through the outlet cabinet 110 and the capacitor cabinet 120 in the horizontal direction. However, it is not limited to this. In other embodiments, the connecting busbar 130 can also be extended in an inclined direction or in a vertical direction, and the extension direction of the connecting busbar 130 is not specifically limited.
[0027] It should be noted that the box-type substation 100 further includes a first conductive bar 140 and a second conductive bar 150. The first end 131 is connected to the main current-carrying bar 111 through the first conductive bar 140. The first conductive bar 140 is used to conduct the first end 131 and the main current-carrying bar 111 to achieve electrical connection between the busbar 130 and the main current-carrying bar 111. The first conductive bar 140 is also used to fix the relative position of the first end 131 and the main current-carrying bar 111 to prevent the first end 131 from being displaced relative to the main current-carrying bar 111. The second end 132 is connected to the circuit breaker 121 through the second conductive bar 150. The second conductive bar 150 is used to conduct the second end 132 and the circuit breaker 121 to achieve electrical connection between the busbar 130 and the circuit breaker 121. The second conductive bar 150 is also used to fix the relative position of the second end 132 and the circuit breaker 121 to prevent the second end 132 from being displaced relative to the circuit breaker 121.
[0028] Furthermore, the position of the second end 132 corresponds to the position of the circuit breaker 121, and the second conductive bar 150 is arranged in a U shape to reduce the space occupied by the second conductive bar 150 while ensuring the conduction effect between the second end 132 and the circuit breaker 121, shorten the length of the connecting bus 130, and realize the rational use of the space in the capacitor cabinet 120.

The limiting groove 171 is used to limit the connecting busbar 130 to prevent the connecting busbar 130 from being displaced in the width direction of the limiting groove 171. One side of the connecting busbar 130 abuts against the bottom wall of the limiting groove 171, and the other side abuts against the first partition 160. The bottom wall of the limiting groove 171 and the first partition 160 work together to limit the connecting busbar 130 to prevent the connecting busbar 130 from being displaced in the depth direction of the limiting groove 171.

[0033] In this embodiment, the box-type substation 100 further includes a plurality of insulating blocks 180 , each of which is disposed between two adjacent connecting busbars 130 to ensure the isolation effect of the two adjacent connecting busbars 130 and prevent the two adjacent connecting busbars 130 from contacting and conducting.
[0034] In this embodiment, the number of the connecting busbars 130 is three, the number of the insulating blocks 180 is two, the three connecting busbars 130 are arranged in parallel and spaced apart, and each insulating block 180 is sandwiched between two adjacent connecting busbars 130.
