Description
Technical Field
The utility model relates to a SF6 semi-insulating looped netowrk cabinet, in particular to SF6 semi-insulating looped netowrk cabinet convenient to operation maintenance.
Background
With large-scale urban construction, a large number of large-scale high-rise buildings are pulled out, the power transformation and distribution station is often arranged below a building, the power transformation and distribution equipment must be oilless according to the fire-fighting requirement, the power transformation and distribution equipment should be miniaturized according to reasonable use of the construction area, and then the ring main unit enters the building. The ring main unit is simple in structure, reliable and safe in operation, small in maintenance amount and low in operation cost, and has outstanding advantages compared with a switch cabinet provided with a circuit breaker. The ring main unit requires that the load switch has higher performance, smaller volume and independent operation room, thus enhancing reliability, reducing interference and having more stable operation, which expands the application range of the ring main unit.
The S-ring main unit is an electrical device with a group of high-voltage switch devices arranged in a steel plate metal main unit body or made into an assembled interval ring main unit, and the core part of the S-ring main unit adopts a load switch and a fuse, so that the S-ring main unit has the advantages of simple structure, small volume, low price, capability of improving power supply parameters and performance, power supply safety and the like. But in the last instrument room of original integral type, put secondary control part and operating device part in same incasement, secondary control part is changed or is overhauld and open the door plant and can see on-off mechanism simultaneously, has certain potential safety hazard, and easy production is disturbed during the operation, influences equipment operating stability.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a by last door, well door and middle space baffle triplex combination is provided, fall into the mechanism room on, lower secondary control room and independent load switch room two parts, independent load switch room ensures that the cupboard all need not the operation of opening the door under any circumstance, the fail safe nature has been increased, independent secondary control room is when any needs change components and parts or look over inside secondary running state, can open at any time, need not to contact with the load switch room, the intermediate bottom that increases is better with last, electrical interference between the lower falls to minimumly, the SF6 semi-insulating looped netowrk cabinet of the operation maintenance of being convenient for of having increased the operating stability of equipment.
In order to solve the technical problem, the utility model provides a SF6 semi-insulating looped netowrk cabinet convenient to operation maintenance, its characterized in that: the metal fully-enclosed structure cabinet is characterized by comprising a shell and a cabinet body which are assembled by bending steel plates and fastening screws, wherein the cabinet body is composed of a top plate, a mechanism chamber, a lower bottom plate, a front panel, a rear panel, an upper back plate, a lower back plate, a left side plate and a right side plate, the cabinet body is provided with an upper door plate, a middle door plate and a lower door plate in the front, the mechanism chamber is composed of the upper door plate, the middle door plate and a middle partition plate, and the mechanism chamber is divided into an upper secondary control chamber, a lower secondary control chamber and an independent load switch.
Preferably, the lower door plate is provided with an observation window for observing the positions of the load switch and the grounding switch.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a mechanism's room is by last door, well door and well intermediate spacer triplex combination, fall into mechanism's room, lower secondary control room and independent load switch room two parts, independent load switch room ensures that the cupboard all need not to open the door operation under any circumstance, the fail safe nature has been increased, independent secondary control room is at any time need change components and parts or when looking over inside secondary running state, can open at any time, need not to contact with the load switch room, the better with upper and lower electric interference of intermediate bottom that increases falls to minimumly, the operating stability of equipment has been increased.
