Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Refer to Fig. 1, shown in figure is a kind of anti-interior arcing metal clad switchgear, include cabinet 1 and handcart 2 two parts, described cabinet will be divided into control room 11, handcart room 12, bus-bar room 15, cable vault 13 and pressure releasing chamber 14 by dividing plate in cabinet, described pressure releasing chamber is positioned at the top of described cable vault and described bus-bar room; The end face of described bus-bar room has the bus-bar room explosion relief 4 being communicated with described bus-bar room and described pressure releasing chamber, described bus-bar room explosion relief place has bus-bar room release of pressure cover plate 6, and the end face of wherein a side and the described bus-bar room of described bus-bar room release of pressure cover plate is connected through the hinge; The end face of described cable vault has the cable vault's explosion relief 3 being communicated with described cable vault and described pressure releasing chamber, explosion relief place of described cable vault has cable vault's release of pressure cover plate 5, and the end face of wherein a side and the described cable vault of described cable vault release of pressure cover plate is connected through the hinge; The size of described bus-bar room explosion relief is greater than the size of described cable vault explosion relief.In the present embodiment, the end face of described bus-bar room and the end face place same level of described cable vault, the described hinge system at described bus-bar room release of pressure cover plate place is arranged at the back side edge of described bus-bar room release of pressure cover plate, and the described hinge system at release of pressure cover plate place of described cable vault is arranged at the front side edge of described cable vault release of pressure cover plate.The described hinge quantity at described bus-bar room release of pressure cover plate place has 5 at least, and the described hinge quantity at release of pressure cover plate place of described cable vault has 5 at least.There is the first sealing ring between the end face of described bus-bar room release of pressure cover plate and described bus-bar room, between the end face of described cable vault release of pressure cover plate and described cable vault, have the second sealing ring.In the present embodiment, there is one first lid panel notches the bottom surface of described bus-bar room release of pressure cover plate, described first sealing ring is placed in described first lid panel notches; There is one second lid panel notches the bottom surface of described cable vault release of pressure cover plate, and described second sealing ring is placed in described second lid panel notches.
Described dividing plate adopts 2mm thick aluminizing zinc steel plate, and the equal ground connection of described dividing plate is arranged.Although owing to have employed the aluminizing zinc steel plate with improved corrosion and antioxygenic property, in manufacturing cost, more domestic like product is higher, and it all has the incomparable superiority of other products in structure and performance.
When switch cubicle pressure increase, first bus-bar room release of pressure cover plate, cable vault's release of pressure cover plate action are opened.The air displacement of release of pressure is smooth and easy, and decompression rate exceedes arc burning pressure ramp-up rate, then cabinet internal pressure continues to rise seldom, and after continuing the regular hour, drop to zero rapidly, thus the cabinet door of switch cubicle can not be rushed to open, and ensures product safety.
Below only have expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
