The cable compartment is provided with a lower isolation blade and a plurality of binding posts inside. The box door is pivoted on the box body and is provided with a door lock. metal enclosed box-type switchgear is simple and compact in structure, and the box body is divided into independent rooms, so overall arrangement is reasonable, sequent wiring is convenient, and subsequent maintenance is convenient.
Description
[technical field]
The utility model relates to a kind of switch cubicle, is specifically related to a kind of metal enclosed box type switch equipment, belongs to the technical field of power equipment.
[background technology]
Switchgear is a kind ofly after electric power network step-down, carry and distribute the equipment of electric power, and it is widely used in different places, as places such as, skyscraper, residential quarters, industrial and mining enterprises, construction sites; It is also applicable in the electric power systems such as box-type substation.
The metal enclosed switchgear of prior art is as shown in No. 201320237937.1st, People's Republic of China's utility model patent, its interior layout is unreasonable, between each chamber, does not significantly separate, and easily causes circuit disorderly and unsystematic, inconvenience maintenance, and fail safe is also poor.
Therefore,, for solving the problems of the technologies described above, the necessary one that provides has structure improved metal enclosed box type switch equipment, to overcome described defect of the prior art.
[utility model content]
For addressing the above problem, it is a kind of simple in structure, rationally distributed that the purpose of this utility model is to provide, and the metal enclosed box type switch equipment maintaining easily.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of metal enclosed box type switch equipment, and it comprises casing and chamber door, is divided into bus isolation ward, circuit breaker isolation ward, cable compartment and instrument compartment in described casing; In described bus isolation ward, isolation knife is installed; In described circuit breaker isolation ward, current transformer and vacuum circuit-breaker are installed; Lower isolation knife and some binding posts are installed in described cable compartment; Described chamber door is articulated on casing, establishes a door lock on it.
Metal enclosed box type switch equipment of the present utility model is further set to: on described casing, be also provided with suspension ring.
Metal enclosed box type switch equipment of the present utility model is further set to: it further comprises a spring operating mechanism, and this spring operating mechanism and vacuum circuit-breaker are integrated, and its connection is also controlled vacuum circuit-breaker.
Metal enclosed box type switch equipment of the present utility model is also set to: be provided with some heat radiation slotted holes in described casing.
Compared with prior art, the utlity model has following beneficial effect: metal enclosed box type switch equipment of the present utility model is simple in structure, compact, it will be divided into separate chambers in casing, thus make rationally distributed, easily and orderly wiring, be also convenient to follow-up maintenance.
[accompanying drawing explanation]
Fig. 1 is the structural representation of metal enclosed box type switch equipment of the present utility model.
Fig. 2 is the front view of metal enclosed box type switch equipment of the present utility model.
[embodiment]
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of metal enclosed box type switch equipment, and it comprises casing 1 and chamber door 2.
Wherein, in described casing 1, be divided into bus isolation ward 3, circuit breaker isolation ward 4, cable compartment 5 and instrument compartment 6; In described bus isolation ward 3, isolation knife 7 is installed; Current transformer 8 and vacuum circuit-breaker 9 are installed in described circuit breaker isolation ward 4; Lower isolation knife 10 and some binding posts 11 are installed, to facilitate wiring in described cable compartment 5.Described upper isolation knife 7, current transformer 8, vacuum circuit-breaker 9, lower isolation knife 10 all can provide protection to the safe operation of this switchgear.
Further, be provided with suspension ring 12 in described casing 1, thereby be convenient to the transhipment of this switchgear and install.Metal enclosed box type switch equipment of the present utility model further comprises a spring operating mechanism 13, and this spring operating mechanism 13 is integrated with vacuum circuit-breaker 9, and its connection is also controlled vacuum circuit-breaker 9, and can manipulate vacuum circuit-breaker 9.The operating characteristics of this spring operating mechanism 13 and arc control device folding desired properties are more identical, reduce unnecessary intermediate transmission link, have reduced energy consumption and noise, make the operating characteristics of circuit breaker more reliable.On described casing 1, be also provided with some heat radiation slotted holes 14, thereby be convenient to switchgear heat radiation.
Described chamber door 2 is articulated on casing 1, establishes a door lock 15 on it, thereby can close this switchgear, guarantees to use safety.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection range of this creation within all spirit in this creation and principle.
