Description
Technical field
This utility model relates to a kind of switch cubicle, particularly to a kind of fixed exchange loop-network switch cabinet of box, belongs to electric power project engineering field.
Background technology
The time that ring main unit occurs is not very long, but it is widely used in a variety of applications, the building of this industrial undertaking got up mainly due to new development and public institution, from the angle for distribution, it is usually no more than 1250KVA for its distribution transformer of great majority with medium and small capacity, can steady in a long-term powering, high-voltage switch gear infrequently operates.For this kind of user, though the performance of ring main unit is not the most perfect, but enough adequate.Along with large-scale urban construction, a large amount of large-scale tall buildings things are rised sheer from level ground, transformer and distribution station is often just located at downstairs, according to fire-fighting requirements, distribution equipment necessary " non-oil ultra high vacuum system ", according to the reasonable employment building area, distribution equipment should " miniaturization ", then ring main unit or vacuum circuit breaker, dry-type transformer, dry type mutual inductor has been put into flickering building.But traditional ring main unit structure is simple not, runs less reliable safety.
Summary of the invention
For solving the technical problem on the above-mentioned tradition fixed loop networks switch cabinet of box, this utility model provides a kind of fixed exchange loop-network switch cabinet of box.
This utility model be the technical scheme is that a kind of fixed exchange loop-network switch cabinet of box, it is made up of cabinet, bus, pull operation mechanism, on-load switch, fuse summation current transformer, cabinet is fully assembled structure and is divided into bus-bar room, control room, switch gear room and cable vault, bus-bar room is in the upper end of cabinet the partition space being isolated into intercommunication by partition panel, control room is in the front side of cabinet upper end and it is isolated with bus-bar room by partition panel, switch gear room is in the centre of cabinet, and it is isolated with switch gear room by cable vault in the lower end of cabinet and by partition panel；Bus is arranged on bus-bar room, pull operation mechanism is arranged on the front side of switch gear room, on-load switch is arranged on rear side of the pull operation mechanism of switch gear room, fuse is arranged between bus-bar room and switch gear room, current transformer is arranged on the cable vault of bottom of cabinet bulk, and pull operation mechanism, on-load switch, fuse summation current transformer are connected by connecting line row.
The beneficial effects of the utility model are: the fixed exchange loop-network switch cabinet simple in construction of box of the present utility model, reliable and safety, maintenance capacity is only small, and operating cost is low, and compared with the switch cubicle equipped with chopper, advantage is very prominent.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model is further illustrated:
Fig. 1 is side structure schematic diagram of the present utility model.
In figure 1, cabinet, 2, bus, 3, pull operation mechanism, 4, on-load switch, 5, fuse, 6, current transformer, 7, bus-bar room, 8, switch gear room, 9, cable vault.
Detailed description of the invention
In the embodiment in figure 1, a kind of fixed exchange loop-network switch cabinet of box, it is made up of cabinet 1, bus 2, pull operation mechanism 3, on-load switch 4, fuse 5 summation current transformer 6, cabinet 1 is for fully assembled structure and is divided into bus-bar room 7, control room, switch gear room 8 and cable vault 9, bus-bar room 7 is in the upper end of cabinet 1 the partition space being isolated into intercommunication by partition panel, control room is in the front side of cabinet 1 upper end and itself and bus-bar room 7 is isolated by partition panel, switch gear room 8 is in the centre of cabinet 1, and it is isolated with switch gear room 8 by cable vault 9 in the lower end of cabinet 1 and by partition panel；Bus 2 is arranged on bus-bar room 7, pull operation mechanism 3 is arranged on the front side of switch gear room 8, on-load switch 4 is arranged on rear side of the pull operation mechanism 3 of switch gear room 8, fuse 5 is arranged between bus-bar room 7 and switch gear room 8, current transformer 6 is arranged on the cable vault 9 bottom cabinet 1, and pull operation mechanism 3, on-load switch 4, fuse 5 summation current transformer 6 are connected by connecting line row.
Embodiment: this utility model is applicable to the distribution system of exchange 3.6 ~ 12KV/50Hz, is widely used in Construction of Intercity Network and transformation, industrial and mining establishment, skyscraper and communal facility etc..The on-load switch 4 of this ring main unit adopts vacuum load switch 4, and namely pull operation mechanism 3 is manually operable, it is possible to electric operating.
