Each of the single phases of dual-pole type includes a circuit breaker, a current transformer and an isolated grounded switchgear longitudinally disposed along the bottom frame, wherein the circuit breaker, the current transformer and the switchgear are all sealed inside a casing filled with SF6 gas. The three-phase distribution box outdoor high-voltage plug switchgear has the advantages of more compact and reasonable structure, high switching capacity, more stable and reliable actions and the like.
Description
Technical field
The utility model relates to a kind of high-voltage appliance switch equipment technical field, specifically a kind of three-phase branch mailbox outdoor high-voltage plug-in type combined electrical apparatus.
Background technology
Cubicle Gas-Insulated Switchgear (be called for short GIS) compact conformation, floor space is little, reliability is high, the operation maintenance workload is little but cost an arm and a leg, overhaul difficulty, the environmental pollution degree is big; Air insulation switchgear (be called for short AIS) price is low, maintenance is convenient, flexible but floor space greatly, poor reliability, maintenance cost height.The plug-in type switch is a kind of novel outdoor high-voltage electric equipment between conventional air insulation switchgear (AIS) and gas-insulated switchgear (GIS).But this switch that domestic manufacturer produces all adopts external imported components to assemble, and price is higher, and capacity of will is poor, does not have the property right of oneself.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of compact conformation reasonable, and connecting-disconnecting function is strong, moves reliable and stable and price is lower, has the three-phase branch mailbox outdoor high-voltage plug-in type combined electrical apparatus of autonomous property right.
The technical solution adopted in the utility model is: a kind of three-phase branch mailbox outdoor high-voltage plug-in type combined electrical apparatus, comprise that underframe, spring mechanism, centralized control cabinet and three are single-phase, and the centralized control cabinet is arranged on the underframe below, and spring mechanism is arranged on underframe one side; Each single-phase comprising: circuit breaker, current transformer and isolation ground connection unit switch, the circuit breaker that each is single-phase, isolating switch, isolating the ground connection unit switch all is enclosed in the housing that is filled with SF6 gas, described single-phase be two pillars, promptly comprise two compound insulating sleeves, described circuit breaker is horizontal self-energy quenching arc circuit breaker, this circuit breaker is horizontally installed on the underframe, that side near spring mechanism, the other end of circuit breaker connects current transformer, isolate the ground connection unit switch and have two, be separately positioned on the top at the both ends of circuit breaker summation current transformer, two compound insulating sleeves are separately positioned on two tops that isolate the ground connection unit switch.
Circuit breaker is a horizontal type structure, and three-phase divides box, adopts the three-phase combined operation, isolates the ground connection unit switch and arranges vertically that along underframe its moving contact adopts the Mume flower contact formula, and built on stilts bus connects.
Each single-phase employing two pole structure of the utility model, its part all vertically is provided with along underframe, and structure is compact more, and it is more reasonable to arrange; Adopt horizontal self-energy quenching arc circuit breaker, its connecting-disconnecting function is strong, and the arcing time is short, guarantees reliable; Isolate the ground connection unit switch and vertically be provided with and adopted Mume flower contact, simple and compact for structure, through-current capability is strong, cuts circulation and little electric current reliability height; Improved overall performance of the present utility model in sum from every side.

Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprises that mainly spring mechanism 1, underframe 8, centralized control cabinet 9 and three are single-phase.Centralized control cabinet 9 is arranged on the underframe below, and spring mechanism 1 is arranged on underframe one side.Each single-phase comprising: circuit breaker 5, current transformer 6 and isolation ground connection unit switch 2, each single-phase circuit breaker 5, current transformer 6, isolation ground connection unit switch 2 all are enclosed in the housing that is filled with SF6 gas.Described single-phase be two pillars, promptly comprise two compound insulating sleeves 7, described circuit breaker 5 is horizontal self-energy quenching arc circuit breaker, the connecting-disconnecting function of this circuit breaker 5 is strong, the arcing time short, standard-sized sheet break times 2 cycle, electric life is long, and full capacity cut-offs 20 times, simple and reliable for structure.Described circuit breaker 5 is horizontally installed on the underframe, that side of close spring mechanism 1, and the other end of circuit breaker 5 connects current transformer 6.Isolate the top that ground connection unit switch 2 is separately positioned on the both ends of circuit breaker 5 summation current transformers 6 for two, isolating switch 3 in the isolation ground connection unit switch 2 of present embodiment and earthed switch 4 are for vertically to arrange along underframe, can reduce width like this, save horizontal space, its inner moving contact adopts quincunx contact, and that Mume flower contact has is simple and compact for structure, through-current capability strong, cut circulation and the high advantage of little electric current reliability.The utility model adapted mature C J motor drive mechanism, stable operation is reliable, defencive function is complete, satisfies five anti-requirements.Two compound insulating sleeves 7 are separately positioned on two tops that isolate ground connection unit switch 2, adopt turnover thread casing overhead wire to connect.
During transportation, the plug-in type combined electrical apparatus is the outer whole Transporting of decannulation, only needs mounting sleeve to get final product when therefore install at the scene, and owing to adopting underframe and pillar to fix, on-the-spot need be watered the dress anchor bolt, and on-the-spot installation is simple and convenient.
This shows that the utlity model has and arrange novelly, compact conformation is reasonable, connecting-disconnecting function is strong, move reliable and stable, advantage such as maintenance is convenient, and brand-new combined electrical apparatus form will provide a kind of new construction module to newly-built transformer station and old power plant retrofit.
