Abstract
The utility model relates to a combined high-voltage switch device which is divided into an independent pressure relief channel and an air discharging hood by a composite board and a metal plate and is connected by bolts. The solid frame of the utility model is provided with module holes in a preforming way by side frames. The utility model has the advantages of reasonable design, simple structure, shapely configuration, favorable manufacturing process floor space saving and high safety and also avoids damage to the equipment and people caused by the way that air with high temperature and high pressure is discharged when a failure occurs. Because of the full composite structure, deviation of the size and deformation caused by welding can be avoided, raising the production quality, adding the commonality of the parts of the complete set of equipment and bringing convenience for carrying out big production of industrialization.
Description
The utility model relates to high pressure double-level-metal sealing switch equipment, particularly with the full composite type double layer switch installation of independent pressure release passage.
At present, in the electric power system, the high pressure double layer switch installation day by day demonstrates its advantage, it has the floor space of saving, construction cost, safeguards characteristics easy to use, but present double layer switch installation, all fail to solve down the pressure release passage problem of handcart chamber, following cable vault, during fault, the high temperature of generation, gases at high pressure can't normally be discharged once be short-circuited herein, must destroy equipment and harm operating personnel's safety; And frame structure is a Welding Structure, causes dimensional discrepancy and distortion easily because of welding, and has a strong impact on product quality, is unfavorable for the demand of modernization industry.
The purpose of this utility model is at above deficiency, provides a kind of each compartment to have independent pressure release passage, the full assembly type double layer switch installation of non-welding.
The double-deck movable metal enclosed switchgear of armouring type, comprise handcart chamber hood 1, following handcart chamber pressure release passage 13, assembly type handcart 16 and preceding cabinet 19, back cabinet 20 etc., it is characterized in that the composite plate 14 that metallic plate and insulation board are formed is divided into handcart chamber 15 and following handcart chamber pressure release passage 13, they are communicated with handcart chamber hood 11 and following handcart chamber hood 2 respectively; Metallic plate 8 is divided into cable vault 4 and following cable vault pressure release passage 9, and they are communicated with cable vault's hood 6 and following cable vault hood 7 respectively; Cabinet side frame 22,23 limit portions and cabinet crossbeam 21,24 ends are provided with some digital and analog holes, crossbeam 21,24 and side frame 22,23, and preceding cabinet 19 adopts bolt 25 to be connected with back cabinet 20; Shirt rim, Contact Cover 3 outer setting, three road, anterior fixed contact and insulating material sleeve lengthening, handcart 16 is full fabricated structure.
The utility model is pressure release passage and cabinet body frame structure, the improvement of handcart structure, the setting of passage, mainly show: go up handcart chamber 15 by hood 1 pressure release of last handcart chamber, following handcart chamber 11 is by handcart chamber pressure release passage 13 and hood 2 pressure releases of following handcart chamber down, last cable vault 4 is by hood 6 pressure releases of last cable vault, following cable vault 10 is by cable vault's pressure release passage 9 and hood 7 pressure releases of following cable vault down, particularly the composite plate 14 of metallic plate and insulation board composition is divided into big or small two parts with preceding layer cashier's office in a shop, moving contact 12 insulation against ground distances had both been guaranteed, handcart chamber 15 and following handcart chamber 11 are separated fully, make when solving following handcart chamber pressure release passage, meet the designing requirement of armouring switch cubicle again; To go up cable vault's 4 usefulness metallic plates, 8 sealings, and make the cabinet rear portion form an interlayer, become the pressure release passage 9 of cable 10 down; Adopt non-welded main frame, all parts all adopt cold-rolled steel sheet to bend moulding, and wherein side frame limit portion is provided with the digital and analog hole of constant spacing, and crossbeam is connected by bolt with side frame, and mounting rail also can be fixed on the framework at an easy rate; The Contact Cover of sleeve lengthening, increased creepage distance, improved the class of insulation, the fixed contact 17 of the cable chamber 4 that powers on can normally be connected with last handcart chamber 15, can separate fully with following handcart chamber 11 again, guaranteed the sectional area of time handcart chamber pressure release passage 13 simultaneously, handcart 16 has also adopted full fabricated structure simultaneously.
The utility model is reasonable in design, simple in structure, modern design is attractive in appearance, the manufacturing process exquisiteness, save floor space, the security reliability height, entire product adopts full fabricated structure, avoided the dimensional discrepancy and the distortion that cause because of welding, increased the versatility of switchgear assembly part, be convenient to the standardization of part, seriation and tissue are produced in batches, satisfy IEC-298 " ac metal closing switch gear and control appliance ", the requirement of GB3906 " 3～35KV ac metal closing switch gear " and related standards, has " five is anti-" blocking function, can under full working condition, work, it is the power plant, transformer station, the desirable controller switching equipment of skyscraper etc. is easy to penetration and promotion.
The utility model accompanying drawing 1 is the internal structure schematic diagram, and Fig. 2 is a front view, and Fig. 3 is frame structure (dissection) schematic diagram, and Fig. 4 is Fig. 3 A dot structure figure, and Fig. 5 is its upward view; Fig. 6 is Fig. 3 B dot structure figure, and Fig. 7 is its end view; Fig. 8 is Contact Cover 3 structural representations.Wherein go up handcart chamber hood 1, following handcart chamber hood 2, Contact Cover 3, last cable vault 4, bus-bar room 6, last cable vault hood 6, following cable vault hood 7, metallic plate 8, following cable vault pressure release passage 9, following cable vault 10, following handcart chamber 11, moving contact 12, following handcart chamber pressure release passage 13, composite plate 14, last handcart chamber 15, circuit breaker cart 16, fixed contact 17, instrument box 18, preceding cabinet 19, back cabinet 20, preceding cabinet crossbeam 21, preceding cabinet side frame 22, back cabinet side frame 23, back cabinet crossbeam 24, bolt 25.
