Description
Technical Field
The utility model belongs to the technical field of electrical system, concretely relates to generating line system of cubical switchboard arranges transform structure.
Background
The switch cabinets are usually arranged in rows along the transverse direction, each switch cabinet is provided with a bus chamber, the transverse projection positions of the bus chambers of the switch cabinets are the same, and bus copper bars are installed in the bus chambers. The bus copper bar is arranged in a bus chamber of the switch cabinet to ensure that each switch cabinet forms electrical connection, and the bus is abbreviated in a row; still some other copper bars lug connection electric elements (for example current transformer, circuit breaker, isolation trolley) are in the cubical switchboard inside, and the copper bar of this type lug connection electric elements is called the guide copper bar, and the guide copper bar is not the generating line copper bar.
The busbar copper has three phases A/B/C, and enough electric gaps are required between the three phases. In addition, according to the regulations of the related technical standards, the distribution and arrangement of the copper rows of the a/B/C three-phase bus in space must have a uniform sequence rule, which is called phase sequence, and the phase sequence of the switch cabinet is generally arranged in A, B, C from left to right, from top to bottom and from back to front facing the front of the switch cabinet. In order to obtain a larger electrical gap in a limited space of a bus chamber of an incoming line switch cabinet and an outgoing line cabinet, according to the existing industry and standards of southern power grids, the transverse projection positions of three-phase bus copper bars of a 10kV switch cabinet (except an incoming line isolation cabinet) are arranged in a triangular shape, such as a delta shape or a right-angled triangle.
As shown in fig. 1, 2, and 3, each row of switch cabinets generally includes an incoming isolation cabinet 1, an incoming switch cabinet 2, an outgoing cabinet 3, and the like. Seen from the connection relation and the current direction, the incoming isolation cabinet 1 is connected with an external power supply and is located at the most upstream, the incoming switch cabinet 2 is located at the downstream of the incoming isolation cabinet 1, the spatial position of the incoming isolation cabinet is adjacent to the incoming isolation cabinet 1, each outgoing cabinet 3 is located at the downstream of the incoming switch cabinet 2, and each outgoing cabinet 3 provides electric power to a path of corresponding downstream power circuit through the bus copper bars 18, 28 and 38 of the bus chamber. The ABC three-phase vertical incoming line copper bars 10, 20 and 30 are arranged above the top of the incoming line isolation cabinet 1, extend into a bus chamber of the incoming line isolation cabinet 1 from the outside along the vertical direction, and are arranged in the same vertical plane along the transverse arrangement; an isolation trolley 71 and a first current transformer 61 are installed in the incoming line isolation cabinet 1, a main breaker trolley 72 and a second current transformer 62 are installed in the incoming line switch cabinet 2, the first current transformer 61 is located at the rear lower part of the incoming line isolation cabinet 1, and the second current transformer 62 is located at the rear lower part of the incoming line switch cabinet 2; each outlet cabinet 3 is provided with a breaker trolley 73. The ABC three-phase vertical incoming line copper bar vertically penetrates through a bus chamber of the incoming line isolation cabinet from the outside of the top of the incoming line isolation cabinet 1 downwards and then is connected to the input end of an isolation trolley 71, the output end of the isolation trolley 71 is connected to the input end of a first current transformer 61 through a three-phase guide copper bar, the output end of the first current transformer 61 is connected to the input end of a second current transformer 62 through a transversely extending three-phase guide copper bar, the transversely extending three-phase guide copper bar extends into the bottom of the incoming line isolation cabinet 1 to form a bottom of the incoming line switch cabinet 2, and the output end of the second current transformer 62 is connected to the input end of a main circuit breaker trolley 72 through the three-phase guide copper bar; ABC three-phase bus copper bars 11, 12 and 13 are arranged in bus chambers of the incoming line switch cabinet, the ABC three-phase bus copper bars are connected with the output end of the main breaker trolley 72 through three-phase guide copper bars, the ABC three-phase bus copper bars 11, 12 and 13 in the bus chambers of the incoming line switch cabinet 2 extend along horizontal straight lines and enter the bus chambers of the outgoing line cabinets 3 to form outgoing line cabinet transverse bus copper bars 18, 28 and 38, and the ABC three-phase transverse bus copper bars in the outgoing line cabinet bus chambers are connected to the input ends of the corresponding breaking circuit trolley 73 through the guide copper bars.
It can be seen from the above that, the incoming isolation cabinet 1 and the incoming switch cabinet 2 are used in combination, and jointly play a role in connecting and disconnecting the bus copper bar transversely penetrating through the bus chambers of the entire row of switch cabinets from the left and right with the upstream power supply, wherein the main breaker trolley 72 is used for controlling the on-off of all the lines, which is equivalent to playing a role of a main switch of all the lines; and the breaker trolley 73 of each outlet cabinet is used for controlling the on-off of a corresponding road electric line.
Among the above-mentioned structure of current, inlet wire isolation cabinet 1 is only fit for arranging at the leftmost end or the rightmost end of each row of cubical switchboard, makes the arrangement position of cubical switchboard receive the restriction. The reason for this is as follows: because the space size of the bus chamber is limited, the bus chamber can only just contain three-phase bus copper bars which are arranged in a triangular shape generally, and the bus chamber of the incoming line isolation cabinet 1 needs to be provided with three-phase vertical incoming line copper bars, as shown in fig. 1, the bus copper bars cannot be directly connected with the vertical incoming line copper bars (because an isolation trolley, a main breaker trolley and a current transformer must be arranged in the middle), so that the bus chamber of the existing incoming line isolation cabinet 1 cannot be provided with the three-phase buses which are arranged in a triangular shape; further, suppose that the incoming line switch cabinet 2 is arranged on the right side of the incoming line isolation cabinet 1, as shown in fig. 1 and fig. 2, the three-phase buses of all the switch cabinets on the right side of the incoming line isolation cabinet 1 are arranged into a triangle, so the three-phase buses arranged in the triangle on the right side of the incoming line isolation cabinet 1 cannot pass through the bus chamber of the incoming line isolation cabinet 1 to the left and continue to extend to the left, which means that the three-phase bus power supply cannot be directly conveyed to the left side of the incoming line isolation cabinet 1, i.e., the outgoing line cabinet cannot be arranged on the left side of the incoming line isolation cabinet, so that the incoming line isolation cabinet 1 can only be arranged at the leftmost end of the whole row of switch cabinets, and the later expansion is not facilitated. Certainly, if the incoming line isolation cabinet is to be arranged in the middle of a row of switch cabinets, the incoming line switch cabinets 2 can only be arranged on the left side and the right side of the incoming line isolation cabinet 1, which means that two incoming line switch cabinets 2 (including two sets of second current transformers 62 and two sets of main breaker trolleys 72) need to be configured on the switch cabinet in the same row, as shown in fig. 3, one incoming line switch cabinet is wasted, and the investment cost of the transformer substation is undoubtedly increased.
