Abstract
A fixed high-voltage switch cabinet is characterized in that a cable room, a low-voltage instrument room, a busbar room and a circuit breaker room are arranged inside the cabinet body; the low-voltage instrument room and the busbar room are positioned at the upper part of the circuit breaker room; a circuit breaker is mounted inside the circuit breaker room, connected with a current transformer and a voltage transformer respectively, and connected with a lower isolation knife through the current transformer; the entire cabinet body not only has strong corrosion resistance and oxidation resistance but also has higher mechanical strength; meanwhile, the arranged low-voltage instrument room is used for isolating high-low voltage components, so that the layout safety of the entire cabinet body is improved; and the switch cabinet continues the advantages of simple structure and low cost of the fixed cabinet, and greatly decreases the occupied space of the cabinet body on the basis of keeping reasonable and safe clearances.
Description
Technical field
The utility model provides a kind of killer switch cabinet.
Background technology
Now, switch cubicle more and more is tending towards miniaturization, and the user is also more and more higher to the restriction that cabinet takes up an area of the space.Make a general survey of existing fixed formula switch cubicle, comparatively typical cabinet type is GG1A type and XGN type.The fixed switch cubicle volume of GG1A type is bigger, and width generally all reaches more than the 1m, the big and very inconvenience of transportation of floor space.Its mechanical interlocking is an external, function and imperfection, and failure rate is high.Compared to this, the switch cubicle compact conformation, floor space is little, overall dimension: wide * dark * height is 650 * 1000 * 2200 (mm).Cabinet can adopt a whole plate bending to form, so its economy is self-evident.Mechanical interlocking and circuit breaker adopt integrated design, and superior performance has significantly reduced failure rate and misuse rate, has also ensured personal safety effectively.XGN type switch cubicle generally adopts the high voltage load switch of band fuse, but this type of switch can only be confined in certain range of capacity, and does not allow to operate continually, and defencive function is also incomplete.Switch cubicle does not then have this kind limitation, cooperates digital protection equipment can satisfy the various demands of user, has complete protection function the most.Fixed switch cubicle is little with its volume, complete function two big advantages are shown one's talent in the stationary cabinet type, and along with the circuit breaker technology is increasingly mature, also is within sight to the non-maintaining type development, and the advantage of this cabinet type will become increasingly conspicuous.
The utility model content
Based on above-mentioned problem, the purpose of this real utility model is: provide that a kind of compact conformation, floor space are little, safety and stability, fixed high-voltage switch cubicle that failure rate is low.
The technical solution of the utility model is:
A kind of fixed high-voltage switch cubicle, be provided with cable vault, low-voltage instrument chamber, bus-bar room, breaker chamber in cabinet inside, isolation knife down is installed between the cable vault of breaker chamber and bottom, lightning arrester is installed in inside in the cable vault, described low pressure control room and bus-bar room are positioned at the top of breaker chamber, breaker chamber inside is equipped with circuit breaker, circuit breaker is connected with voltage transformer with current transformer respectively, circuit breaker is connected with following isolation knife by current transformer, and the side that described circuit breaker adopts the main conductive circuit three-phase vertically to arrange is adorned fixed vacuum circuit-breaker.
Whole cabinet has very strong corrosion resistance and non-oxidizability, and very high mechanical strength is also arranged.Simultaneously, be provided with the low pressure control room, the high-low pressure components and parts are separated, improved the fail safe of whole cabinet layout; And main busbar adopts yi word pattern to arrange; final under the condition of comprehensive consideration each side factor; compact conformation; but gap and safe distance have still been guaranteed; enough space for maintenances; be aided with the protective value that peace is equipped with again, fixed switch cubicle must satisfy user's all kinds of demands, obtains application more and more widely.
The core of whole cupboard: circuit breaker, the side that adopts the main conductive circuit three-phase vertically to arrange is adorned fixed vacuum circuit-breaker.
Fixed switch cubicle mainly is applicable in the 3-12KV system.Adopt the compound mode of circuit breaker and isolation knife, have complete major loop scheme.Adopt side to adorn fixed vacuum circuit-breaker, the complete machine width dimensions is little, and has perfect machinery and electric interlocking installation, has saved the cabinet space greatly, and its excellent performance has also guaranteed the operation of switch cubicle long-term stability.This switch cubicle has continued that stationary cabinet is simple in structure, the advantage of price economy, is guaranteeing to have reduced the occupation of land space of cabinet greatly on reasonable, the safe basis, gap, and is showing one's talent in like product with its complete protection performance.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the Facad structure figure of fixed high-voltage switch cubicle of the present utility model.
Fig. 2 is the construction profile of fixed high-voltage switch cubicle of the present utility model.
Embodiment
As Fig. 1, shown in Figure 2, fixed high-voltage switch cubicle of the present utility model, be provided with cable vault 4 in cabinet inside, low-voltage instrument chamber 1, bus-bar room 8, breaker chamber, isolation knife 5 down is installed between the cable vault of breaker chamber and bottom, lightning arrester 3 is installed in 4 inside in the cable vault, described low pressure control room 1 and bus-bar room 4 are positioned at the top of breaker chamber, breaker chamber inside is equipped with circuit breaker 3, circuit breaker 3 is connected with voltage transformer 7 with current transformer 6 respectively, circuit breaker 2 is connected with following isolation knife 5 by current transformer 6, and the side that described circuit breaker 2 adopts the main conductive circuit three-phase vertically to arrange is adorned fixed vacuum circuit-breaker.
High-tension switch cabinet has continued the marrow that my company's cabinet is made.Select the aluminizing zinc steel plate of import for use, adopt multiple flanging technology to be made a whole plate, whole cabinet has very strong corrosion resistance and non-oxidizability, and very high mechanical strength is also arranged.Simultaneously, be provided with the low pressure control room, the high-low pressure components and parts are separated, improved the fail safe of whole cabinet layout; And main busbar adopts yi word pattern to arrange, and is final under the condition of comprehensive consideration each side factor, the most at last the cabinet size be contracted to wide * dark * height is 650 * 1000 * 2200 (mm).Volume reduces, compact conformation, but still guaranteed gap and safe distance, enough space for maintenances are aided with the protective value that peace is equipped with again, and fixed switch cubicle must satisfy user's all kinds of demands, obtains application more and more widely.
The core of whole cupboard: circuit breaker, the side that adopts the main conductive circuit three-phase vertically to arrange is adorned fixed vacuum circuit-breaker, and positive size only is 240mm, and this just provides feasibility for dwindling of cabinet volume.
Fixed switch cubicle mainly is applicable in the 3-12KV system.Adopt the compound mode of circuit breaker and isolation knife, have complete major loop scheme.Adopt side to adorn fixed vacuum circuit-breaker, the complete machine width dimensions is little, and has perfect machinery and electric interlocking installation, has saved the cabinet space greatly, and its excellent performance has also guaranteed the operation of switch cubicle long-term stability.This switch cubicle has continued that stationary cabinet is simple in structure, the advantage of price economy, is guaranteeing to have reduced the occupation of land space of cabinet greatly on reasonable, the safe basis, gap, and is showing one's talent in like product with its complete protection performance.
