The alternating current bus cabinet is a core component for realizing electric energy conversion, distribution and system integration in an energy storage conversion system (PCS).
In the prior art, as the demands for miniaturization and energy storage capacity of the energy storage container are increased, the space required by the battery pack is larger and larger, the size of the energy storage converter system is smaller and smaller, and particularly, the limitation on the width is larger and larger, how to reduce the size of the alternating current bus cabinet becomes the problem to be solved by the energy storage container.
Referring to fig. 1-2, an ac bus bar 403 is provided in the present application, and the ac bus bar 403 includes a main breaker 101, a sub-breaker 102, a breaker copper bar, and a main copper bar 104.
Wherein the main breaker 101 has a plurality of input terminals and a plurality of output terminals extending in a first direction to the wiring area 112 at the lower portion of the ac bus bar 403.
1-2, The present application is exemplified by three circuit breakers, a main circuit breaker 101 and a sub circuit breaker 102 each having three inputs and three outputs.
Here, the number of the input terminals and the output terminals of the circuit breaker is not limited, and the type of the circuit breaker may be selected according to actual requirements.
The plurality of sub-circuit breakers 102 are arranged at intervals in the horizontal direction in sequence to form one circuit breaker unit 114, the plurality of circuit breaker units 114 are arranged at intervals in the vertical direction, and the plurality of circuit breaker units 114 are arranged in parallel.
Here, the number of sub-circuit breakers 102 and the number of circuit breaker units 114 in each circuit breaker unit 114 may be set according to the size of the actual ac bus bar 403.
In this way, the single-row sub-circuit breakers 102 which are sequentially arranged at intervals in the horizontal direction are arranged in a plurality of rows, so that a large amount of transverse space is saved.
The circuit breaker copper bars are multiple, one end of each circuit breaker copper bar is connected with one output terminal of one sub circuit breaker 102, the other end of each circuit breaker copper bar forms an output terminal in a wiring area 112 at the lower part of the alternating current bus cabinet 403, and the circuit breaker copper bars are arranged at intervals and are connected with a plurality of output terminals of the sub circuit breakers 102 in a one-to-one correspondence manner.
Here, a plurality of circuit breaker copper bars that the interval set up correspond with a plurality of sub-circuit breakers and are connected, have guaranteed promptly to remain between every circuit breaker copper bar and have had insulating interval, the sub-circuit breaker that the staff of being convenient for again discerns when the wiring corresponds with the copper bar.
Specifically, with continued reference to FIG. 1, the breaker copper bars include a first breaker copper bar 105, a second breaker copper bar 106, and a third breaker copper bar 107.
One end of the first breaker copper bar 105 is connected with the sub-breaker 102 in the first target breaker unit, and the other end of the first breaker copper bar 105 extends to the wiring area 112 at the lower part of the ac bus bar 403 along the first direction to form an output terminal.
The first target circuit breaker unit is a circuit breaker unit near the wiring area 112 at the lower part of the ac bus bar 403, and the first direction is a direction perpendicular to and near the bottom surface of the ac bus bar 403.
Specifically, with continued reference to fig. 1, the second circuit breaker copper bar 106 has a connection portion 108 extending along a first direction, a first bending portion 109 extending along a second direction, and a second bending portion 110 extending along a third direction, and the second circuit breaker copper bar 106 is connected to the sub-circuit breaker 102 in the second target circuit breaker unit 114.
The second target breaker unit is a breaker unit which is not shielded by the main breaker 101 in the extension direction of the copper bar, the second direction is a direction which is horizontal and is close to the back plate of the ac busbar 403, and the third direction is a direction which is horizontal and is far away from the back plate of the ac busbar 403.
In this way, the second circuit breaker copper bar 106 is made to cross the sub-circuit breaker 102 below the second target circuit breaker unit 114 by using the thickness direction of the ac bus bar 403 through the shape formed by the connection portion 108 of the second circuit breaker copper bar 106 extending in the first direction, the first bending portion 109 extending in the second direction, and the second bending portion 110 extending in the third direction, and the wiring terminal is formed in the wiring area 112, so that the problem that after the circuit breakers of multiple rows are formed, the wiring terminal of the circuit breaker is difficult to be wired by a worker due to the dense arrangement of the circuit breakers is avoided.
Specifically, with continued reference to fig. 1, the third breaker copper bar 107 is connected to the sub-breaker 102 in the third target breaker unit 114, and includes a connection portion 108 extending in the first direction, a first bent portion extending in the second direction, a second bent portion 110 extending in the third direction, and a third bent portion 111 extending in the fourth direction.
The third target breaker unit is a breaker unit shielded by the main breaker 101 in the extending direction of the copper bar, and the fourth direction is a direction horizontal and approaching the side plate of the ac busbar 403.
Here, the third breaker copper bar 107 cannot directly extend downward to the junction region 112 due to the blocking of the main breaker 101, and it is necessary to provide a third bent portion 111 extending in the fourth direction so that the third breaker copper bar 107 spans the main breaker 101 or the sub-breaker 102 in the thickness direction and also spans the main breaker 101 in the width direction to form a terminal at the junction region 112.
Here, due to the dense arrangement of the main circuit breaker and the sub circuit breaker, the main circuit breaker blocks the copper bar path of the sub circuit breaker which extends downwards to the wiring area through the copper bar, and the copper bar which is blocked still inconvenient to wire after directly extending to the copper bar of the main circuit breaker.
Specifically, the connection portion and the bending portion of the copper bar of the circuit breaker are fixedly connected, and the first target circuit breaker, the second target circuit breaker and the third target circuit breaker respectively form a plurality of rows of parallel and spaced output connection points in the wiring area 112 at the lower portion of the ac bus-bar 403.
In this way, the output connection points are all formed at the lower part of the alternating current bus cabinet 403, so that the width of the alternating current bus cabinet 403 can be reduced by arranging a plurality of rows of circuit breakers, the wiring difficulty can not be increased by arranging copper bars, and the applicability of the alternating current bus cabinet 403 is ensured.
Further, the positions of the multiple rows of output connection points of the wiring area 112 formed at the lower part of the ac bus bar 403 may correspond to the positions of the sub-circuit breakers 102, for example, the uppermost circuit breaker unit 114 may be disposed at a position closest to the back plate, and the lowermost circuit breaker unit 114 may be disposed at a position furthest from the back plate, so that the problem that it is difficult for a worker to make the multiple output connection points correspond to the circuit breakers is avoided.
As an example, when a plurality of rows of sub-circuit breakers are formed in the ac main tank 403, a plurality of rows of output connection points are also formed at the terminals of the ac main tank, the number of rows of output connection points corresponds to the number of rows of sub-circuit breakers, the arrangement mode of each row of output connection points is the same as that of the sub-circuit breakers, for example, when 3 three sub-circuit breakers are arranged in a row of sub-circuit breakers, among the output connection points corresponding to the row of sub-circuit breakers, the first three output connection points correspond to three output connection points of the first three sub-circuit breakers, the 4 th to 6 th output connection points correspond to the output connection points of the second three sub-circuit breakers, and the last three output connection points correspond to three output connection points of the third three sub-circuit breakers.
When the worker performs wiring, the number of the connection points of the sub-circuit breaker can be determined according to the positions of the output connection points, and the connection point of the sub-circuit breaker corresponding to the connection point is determined according to the structure diagram of the alternating current bus cabinet or the path for searching the copper bar.
In one embodiment, the lengths of the rows of output connection points of the row of output connection points which are farthest from the backboard are shortest, and the lengths of the rows of output connection points of the row of output connection points which are closest to the backboard are longest and the row of output connection points which are closest to the backboard are closest to the bottom, so that the connection of workers is facilitated.
As an example, when a plurality of rows of sub-circuit breakers are formed in the ac bus-bar 403, a plurality of rows of output connection points are also formed at the terminals of the ac bus-bar, the number of rows of output connection points corresponds to the number of rows of sub-circuit breakers, and while the arrangement of each row of output connection points is the same as that of the sub-circuit breakers, a plurality of rows of connection points may be formed, for example, when three rows of sub-circuit breakers are formed in the ac bus-bar 403, the length of the output connection point of the sub-circuit breaker of the lowest row is shortest, a row of connection points farthest from the back plate is formed, the length of the output connection point of the sub-circuit breaker of the uppermost row is longest and closest to the bottom, and the output connection point of the middle row of sub-circuit breakers forms a middle row of connection points, so that for three rows of sub-circuit breakers in the ac bus-bar 403, the connection points of the ac bus-bar 403 are staggered, and thus, no influence of the connection points by other output connection points is avoided by staff, and the staff is more convenient to perform the connection.
The number of main copper bars 104 is plural, each of which is connected to a corresponding one of the input terminals of the main circuit breaker and to a corresponding one of the input terminals of each of the sub-circuit breakers.
Here, the number of the main copper bars 104 is related to the number of the circuit breakers, for example, three circuit breakers are used to obtain three main copper bars 104.
Referring to fig. 2, in the present application, since the sub-circuit breakers 102 are arranged in two rows, the main copper bar 104 is C-like, and when three rows are arranged, the main copper bar 104 is E-shaped, and when more rows are arranged, only more transverse main copper bar 104 parts need to be added in the vertical direction. The lateral dimensions of the main copper bars 104 are related to the position of the sub-circuit breakers 102, and each main copper bar 104 needs to be laterally extended to cover a corresponding position of each sub-circuit breaker 102 to facilitate connection of the sub-circuit breakers 102 to the main copper bars 104.
Here, in order to ensure the insulation effect between the plurality of main copper bars 104, the plurality of main copper bars 104 are arranged along the direction away from the back plate at intervals, that is, the longitudinal interval distance of the main copper bars 104 is ensured, the interval distance of the main copper bars 104 in the thickness direction of the ac bus cabinet is ensured, and the thickness of the ac bus cabinet is further utilized, so that the effect of enhancing the insulation distance between the main copper bars is achieved.
