Abstract
Description
Technical Field
[0001] The utility model relates to a substation, and more specifically, to a container-type substation. Background Art
[0002] In places such as coal mining, substations are needed. The commonly used substation is a step-down substation that converts high voltage into low voltage, such as converting 35 kV high voltage into 10 kV relatively low voltage. The current substation is of a split type and is usually composed of an incoming line cabinet, a transformer cabinet, and an outgoing line cabinet. The incoming line cabinet is used for the access and on-off control of the high voltage to be converted. A step-down transformer is placed in the transformer cabinet. After the input high voltage is stepped down by the transformer, it is output through the outgoing line cabinet. The outgoing line cabinet is used to output the stepped-down voltage through the outgoing line cabinet. Therefore, the high voltage is stepped down by the substation and then input to the load to drive the load to work.
[0003] During the actual application process of the substation, due to the influence of the change of the working site, the position of the substation also needs to be changed. However, since the existing substation is of a split type, during the moving process, the connection cables between the incoming line cabinet and the outgoing line cabinet and the transformer cabinet need to be removed first, and then the substation is moved. After moving to the place, the wiring is carried out again. Therefore, the existing split-type substation is very troublesome when changing the site. If the split-type substation can be designed into an integrated mode, the transfer of the substation will be very convenient.
[0004] If the substation is designed into an integrated mode, not only the heat dissipation problems of the transformer and the control circuit need to be considered, but also the input connection terminals and the output busbars need to be in a dry environment to ensure the long-term stable operation of the substation. Summary of the Invention
[0005] The utility model provides a container-type substation in order to overcome the above technical problems.
[0006] The container-type substation of the utility model includes a box body. The internal cavity of the box body is separated into a transformer cavity, an incoming line cavity, a first switch cabinet cavity, an outgoing line cavity, a second switch cabinet cavity, and a low-voltage cavity by a partition board. It is characterized in that: a 35 kV busbar and a 35 kV switch cabinet are respectively arranged in the incoming line cavity and the first switch cabinet cavity. The 35 kV switch cabinet controls the closing and opening of the 35 kV busbar. An oil-immersed transformer is arranged in the transformer cavity. The oil-immersed transformer steps down the input high voltage. A PLC control cabinet is arranged in the low-voltage cavity. A 10 kV busbar and a 10 kV switch cabinet are respectively arranged in the outgoing line cavity and the second switch cabinet cavity. The 10 kV switch cabinet controls the opening and closing of the 10 kV busbar. Both the incoming line cavity and the outgoing line cavity are closed cavities that are not communicated with the outside.
[0007] For the containerized substation of the present utility model, the transformer chamber is located at one end of the box body, the incoming line chamber and the outgoing line chamber are located at the other end of the box body, the second switchgear chamber is located between the outgoing line chamber and the transformer chamber, and the first switchgear chamber and the low-voltage chamber are arranged between the incoming line chamber and the transformer chamber.
[0008] For the containerized substation of the present utility model, transformer chamber ventilation doors are provided on the box body on both sides of the transformer chamber, and a hollowed-out ventilation door is provided on the box body outside the low-voltage chamber.
[0009] For the containerized substation of the present utility model, a first display screen for information display is provided on the box body outside the incoming line chamber, and a second display screen for information display is provided on the box body outside the transformer chamber.
[0010] For the containerized substation of the present utility model, the transformer chamber ventilation door is composed of two columns and a number of folded plates evenly spaced and fixed between the two columns, and a ventilation slot connecting the transformer chamber and the outside is provided between adjacent two folded plates.
[0011] The beneficial effects of the present utility model are as follows: For the containerized substation of the present utility model, an incoming line chamber, a first switchgear chamber, a transformer chamber, an outgoing line chamber, a second switchgear chamber and a low-voltage chamber are provided in the box body, and a 35 kV busbar, a 35 kV switchgear, an oil-immersed transformer, a 10 kV busbar, a 10 kV switchgear and a PLC control cabinet are respectively arranged therein. In this way, the containerized substation of the present utility model not only realizes the step-down of the input high voltage to a low voltage for output to drive the load to work, but also, since the incoming and outgoing line busbars, switchgears and transformers are all arranged in the same box body, a containerized substation is formed. In this way, when it is necessary to change the position of the substation, only the entire box body needs to be carried. Compared with the existing split-type substation, the cumbersome steps of disconnecting the cable wires before carrying and reconnecting the wires after carrying are omitted, saving manpower and material resources, and also improving the carrying efficiency, which greatly facilitates the position change of the substation according to needs.
[0012] Furthermore, both the incoming line chamber and the outgoing line chamber are airtight cavities not communicating with the outside. In this way, the entry of external moisture and gas into the incoming line chamber and the outgoing line chamber is avoided, ensuring that the 35 kV busbar and the 10 kV busbar are always in a dry environment and ensuring the safe operation of the substation.

Specific embodiments
[0020] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0021] As Figures 1 to 4 shown, the front view, rear view, left view and top view of the container-type substation of the present utility model are respectively given, Figure 5 and Figure 6 its three-dimensional views are all given. The shown container-type substation is composed of a box body 1. The internal cavity of the box body 1 is separated by partitions into a transformer chamber 2, an incoming line chamber 3, a first switchgear chamber 4, an outgoing line chamber 5, a second switchgear chamber 6 and a low-voltage chamber 7. An oil-immersed transformer 8 is arranged in the transformer chamber 2. The oil-immersed transformer 8 steps down and transforms the input high voltage. A 35 kV busbar 9 is arranged in the incoming line chamber 3. The externally input 35 kV AC power supply is connected to the input end of the 35 kV busbar 9. The output end of the 35 kV busbar 9 is connected to the input end of the oil-immersed transformer 8; a 35 kV switchgear 10 is arranged in the first switchgear chamber 4. The 35 kV switchgear 10 is used to control the closing and opening of the 35 kV busbar 9 to control the on-off of the high-voltage input voltage. A PLC control cabinet 11 is arranged in the low-voltage chamber 7. The PLC control cabinet 11 is used to control the operation of the substation.
[0022] In the outgoing line cavity 5, a 10 kV busbar 12 is provided. The input end of the 10 kV busbar 12 is connected to the output end of the oil-immersed transformer 8, and the output end of the 10 kV busbar 12 is connected to the on-site load. In the second switchgear cabinet cavity 6, a 10 kV switchgear 13 is provided, and the 10 kV switchgear 13 controls the closing and opening states of the 10 kV busbar 12. In this way, the input 35 kV voltage is stepped down by the oil-immersed transformer 8 and converted into a 10 kV voltage for output to drive the load to work.
[0023] It can be seen that since the box body 1 is provided with an incoming line cavity 3, a first switchgear cabinet cavity 4, a transformer cavity 2, an outgoing line cavity 5, a second switchgear cabinet cavity 6, and a low-voltage cavity 7, and a 35 kV busbar 6, a 35 kV switchgear 10, an oil-immersed transformer 8, a 10 kV busbar 12, a 10 kV switchgear 13, and a PLC control cabinet 11 are respectively arranged therein, not only is the input high voltage changed into a low voltage to drive the load to work, but also when the substation needs to be transformed, only the entire box body 1 needs to be moved. Compared with the existing split-type substation, the disadvantages of disconnecting the wires before moving and reconnecting the wires after moving are eliminated, which not only saves manpower and material resources, but also improves the position transformation efficiency of the substation.
[0024] The shown transformer cavity 2 is located at one end of the box body 1, the incoming line cavity 3 and the outgoing line cavity 5 are located at the other end of the box body 1, the second switchgear cabinet cavity 6 is located between the outgoing line cavity 5 and the transformer cavity 2, and the first switchgear cabinet cavity 4 and the low-voltage cavity 7 are located between the incoming line cavity 3 and the transformer cavity 2. The shown incoming line cavity 3 and the outgoing line cavity 5 are airtight cavities not communicating with the outside, which avoids the entry of humid air from the outside, keeps the 35 kV busbar 9 and the 10 kV busbar 12 in a dry state all the time, and ensures the stable operation of the substation. A first display screen 17 is provided on the box body 1 outside the incoming line cavity 3, and a second display screen 18 is provided on the box body 1 outside the transformer cavity 2. The first display screen 17 and the second display screen 18 are used for information display.
[0025] A hollow ventilation door 15 is provided on the box body 1 outside the shown PLC control cabinet 11, and the outside air enters the low-voltage cavity 7 through the hollow ventilation door 15 to dissipate heat from the heat-generating components in the PLC control cabinet 11. Transformer cavity ventilation doors 14 are provided on the box body 1 outside the shown transformer cavity 2, so that the outside air enters the transformer cavity 2 through the transformer cavity ventilation doors 14 to dissipate heat from the oil-immersed transformer 8.
[0026] Such as Figure 7As shown in the figure, a perspective view of the ventilation door of the transformer cavity in the present utility model is given. The shown ventilation door 14 of the transformer cavity is composed of two vertical columns 19 and a number of folded plates 20 arranged between the two vertical columns 19. Both vertical columns 19 are arranged vertically, and a number of folded plates 20 are arranged at equal intervals. The two ends of the folded plate 30 are respectively fixed on the two vertical columns 19. A ventilation slot 21 is formed between two adjacent folded plates 30. The outer end of the ventilation slot 21 faces downward and the inner end faces upward. In this way, the outside air can enter the transformer cavity 2 through the ventilation slot 21, while the dust in the air is very difficult to enter the transformer cavity 2 due to the blocking effect of the folded plate 20. The air entering the transformer cavity 2 realizes the heat dissipation of the oil-immersed transformer 8.
