Abstract
A compact-space substation structure comprises a house, dry type transformers and an SF6 gas-insulation medium-voltage switch cabinet, wherein the dry type transformers are arranged on a rear-side wall body of the house, the SF6 gas-insulation medium-voltage switch cabinet is mounted on a left-side or right-side wall body of the house and is connected with a high voltage side of the dry type transformers by a cable. A main wire-inlet low-voltage switch cabinet and a capacitance-compensation low-voltage switch cabinet are disposed on a housing front side of the dry type transformers side by side. Two feed line cabinets are mounted on front of the main wire-inlet low-voltage switch cabinet. A low voltage side of the dry type transformers is connected with the main wire-inlet low-voltage switch cabinet and the two feed line cabinets by busbars. The main wire-inlet low-voltage switch cabinet is connected with the capacitance-compensation low-voltage switch cabinet. The main wire-inlet low-voltage switch cabinet, the capacitance-compensation low-voltage switch cabinet and the two feed line cabinets are the low-voltage switch cabinets of fixed plug-in breakers. The utility model provides the compact-space substation structure capable of reducing an occupation space.
Description
Technical field
The utility model relates to a kind of electric substation structure.
Background technology
For the length and the loss that reduce distribution line in the building, electric substation need be arranged on load center, and load center equipment concentrated area often, the space is restricted.Close-coupled electric substation arranges the layout of having used for reference ripe box-type substation, and limited space has been carried out reasonable use.
Summary of the invention
In order to overcome the bigger deficiency that takes up room of existing electric substation, the tight space electric substation structure that the utility model provides a kind of minimizing to take up room.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of tight space electric substation structure, comprise the house, dry-type transformer and SF6 gas-insulated Medium Voltage Switchgear, described dry-type transformer is positioned at the rear side body of wall in house, described SF6 gas-insulated Medium Voltage Switchgear is positioned at left side or the right side body of wall in house, described SF6 gas-insulated Medium Voltage Switchgear is connected with the high-pressure side of dry-type transformer by cable, the shell front side of described dry-type transformer is arranged side by side main inlet wire low-tension switch cabinet and capacitance compensation low-tension switch cabinet, the feeder line cabinet is arranged in the place ahead of main inlet wire low-tension switch cabinet, the low-pressure side of described dry-type transformer is by busbar and described main inlet wire low-tension switch cabinet, the feeder line cabinet connects, and described main inlet wire low-tension switch cabinet is connected with described capacitance compensation low-tension switch cabinet; Described main inlet wire low-tension switch cabinet, capacitance compensation low-tension switch cabinet and feeder line cabinet are the fixedly low-tension switch cabinet of plug-in circuit breaker.
Further, described dry-type transformer has at least two, and two feeder line cabinets connect back-to-back.
Further, on the right side in described house or the left side body of wall standby low-tension switch cabinet is set.
Technical conceive of the present utility model is: the conventional air-insulated mid-cabinet of SF6 gas-insulated Medium Voltage Switchgear size significantly reduces and whole Operation and Maintenance can be finished before cabinet.The employing fixedly low-voltage cabinet of plug-in circuit breaker can realize operating and maintenance before the cabinet equally.Having can be continuously apart from arranging between the dry-type transformer side of IP40 shell protection grade.
The beneficial effects of the utility model mainly show:
1. press cabinet to adopt the totally-enclosed inflation cabinet of SF6 insulation in, can lean on wall to install, saved maintenance channel behind the cabinet.
2. low-voltage cabinet adopts fixedly plug-in switch, safeguards before the cabinet, can lean on wall and installation back-to-back, safeguards distance after having saved cabinet.
3. dry-type transformer adopts the IP40 shell, and described IP40 is the transformer degree of protection, and Maintenance free distance between transformer case adopts narrow limit to release the transformer body, and the passage of using outside the electric substation is safeguarded, patrolled and examined as transformer, has saved the transformer installing space.
4. high and low voltage switch cabinet interval arranges raised flooring, and is convenient, flexible, is convenient to cable laying.
5. the integral arrangement compactness of electric substation has greatly been saved floor space, and meets code requirement fully.
