Abstract
The utility model discloses a kind of novel breaker ring main unit, comprise cabinet and be arranged at integral type dividing plate in cabinet, cabinet is divided into three parts by described dividing plate, is respectively control room, bus-bar room and cable vault, and control room and bus-bar room are positioned at the top of cable vault side by side; In described cable vault, lower left place is provided with circuit breaker installing rack, and installing rack is provided with side-mounted circuit breaker; The upper right corner, cable vault is provided with current transformer, and current transformer below is provided with earthed switch, and current transformer is connected with side-mounted circuit breaker by copper bar respectively with earthed switch.The utility model is that a kind of environmental protection, volume are small and exquisite, the high pressure the complete sets of equipment of dependable performance, and this product can not only be saved installation space and can effectively reduce the manufacturing cost of equipment.
Description
Technical field
The utility model belongs to ring main unit field, refers to especially a kind of novel breaker ring main unit.
Background technology
Current domestic employing FLN36-12 type on-load switch is as the ring main unit of main switch, due to its have stable and reliable for performance, volume is small and exquisite, the feature such as simple in structure and easy to operate, has obtained user's general favorable comment.Along with the continuous increase of distribution network capacity, this product blemish in an otherwise perfect thing be there is no breaker cabinet, this has also limited the use of such ring main unit to a certain extent, in order to address this problem, the current domestic 3 kinds of circuit breaker ring main units of comparative maturity once that mainly contain: 1) upper isolating switch+side-installed vacuum circuit breaker, advantage is product technology maturation, to high voltage device without particular/special requirement, buying is convenient, shortcoming is that the lower ring main unit volume of manufacturing cost is larger, can not realize the object with looped network cabinet; 2) upper FLN36-12 on-load switch+formal dress VS1 type vacuum circuit-breaker, advantage is product technology maturation, to high voltage device without particular/special requirement, buying is convenient, manufacturing cost is lower, and shortcoming is that manufacturing cost is slightly high, and rated current can only be accomplished 630 A, due to the restriction of structure, can only make segmentation cabinet; 3) upper FLN36-12 on-load switch+side-mounted SF6 circuit breaker, advantage is product technology maturation, the existing similar SF6 circuit breaker supply of existing market, ring main unit volume is small and exquisite, by the design to cabinet, can realize preferably with ring main unit and cabinet, shortcoming is that manufacturing cost is higher, not too suitable for China.
Utility model content
The purpose of this utility model is to provide a kind of have dependable performance, compact conformation, volume is small and exquisite, exploitation is simple and cost performance is high novel breaker ring main unit.
A kind of novel breaker ring main unit described in the utility model, comprise cabinet and be arranged at integral type dividing plate in cabinet, cabinet is divided into three parts by described dividing plate, is respectively control room, bus-bar room and cable vault, and control room and bus-bar room are positioned at the top of cable vault side by side; In described cable vault, lower left place is provided with circuit breaker installing rack, and installing rack is provided with side-mounted circuit breaker; The upper right corner, cable vault is provided with current transformer, and current transformer below is provided with earthed switch, and current transformer is connected with side-mounted circuit breaker by copper bar respectively with earthed switch.
Further improve, described cabinet adopts aluminizing zine plate bolt after CNC machine tooling bending and forming to form.
Further improve, described dividing plate is aluminizing zine plate.
Further improve, described dividing plate is down T-shape.
The beneficial effects of the utility model are:
The fixed miniaturization switch cubicle of indoor alternating current high voltage that this circuit breaker ring main unit is a kind of novel concept, volume is 67% of conventional high-tension switch cubicle, it is a kind of environmental protection, volume is small and exquisite, the high pressure the complete sets of equipment of dependable performance, this product can not only be saved installation space and can effectively reduce the manufacturing cost of equipment; When this circuit breaker ring main unit and conventional ring main unit are supporting, can not only make contact cabinet, can also do into (going out) line cabinet (conventional breaker cabinet does not have this function), appearance design novelty is generous, can, more all sidedly for user provides distribution solution, can meet different instructions for uses; Cabinet, owing to adopting modular construction, has improved the standardization level of product greatly, and this can shorten the production cycle, reduces and produces occupied ground, is conducive to tissue batch production; This cabinet is easy to and existing SF simultaneously
6ring main unit forms the solution of secondary distribution system together, has expanded SF
6the range of application of ring main unit.
