Description

Ring main unit arcing protection cabinet
Technical field
The present invention relates to mesohigh equipment manufacturing technology field, especially a kind of ring main unit arcing protection cabinet.
Background technology
At present, ring main unit is more and more general in the application of distribution system, and power supply department requires that the product of the manufacturer of ring main unit can solve the problem of anti-arcing fault.The ring main unit that most of ring main unit manufacturer produces is not that anti-arcing ability is weak, although reach the ability of the anti-arcing of power supply department requirement exactly, inconvenient in installation and maintenance, and production cost is high.
Summary of the invention
The object of this invention is to provide a kind of ring main unit arcing protection cabinet, it can solve, and looped network cabinet anti-flaming arc ability is weak and installation and maintenance inconvenient, the problem that production cost is high.
In order to solve the problem, the technical solution used in the present invention is: this ring main unit arcing protection cabinet, comprises cable vault's door-plate, left and right, cable vault plate, left and right plate stiffener, rear plate, earthing device.Described cable vault left and right plate is provided with multiple towards outside draw-in groove; Described left and right plate stiffener is housed inside described cable vault left and right plate, between described cable vault left and right plate and described left and right plate stiffener, is provided with anti-flammability insulation board; Described cable vault door-plate is provided with multiple and with described draw-in groove snap fit one to one; The top through hole of described cable vault door-plate is equipped with two blocking levers, and described blocking lever is corresponding with the blocking lever groove above cable vault's door-plate; Be provided with door-plate stiffener inside described cable vault door-plate, the inner side of described rear plate is provided with rear plate stiffener; The base plate of cable vault is provided with pressure release passage; At rear portion, cable vault, median septum is housed, described median septum has hole, every shrouding during described hole is provided with, be connected with described median septum every shrouding in this.
In technique scheme, more specifically scheme can also be: the shape of described draw-in groove is square.
Further: described pressure release passage is a square hole.
Owing to have employed technique scheme, compared with prior art, the beneficial effect had is in the present invention:
1, stiffener is provided with inside cable vault's door-plate, and cable chamber door and blocking lever are interlocked, cable chamber door is unable to lift when ensureing charged, the snap fit of cable vault's door-plate the right and left and the draw-in groove of left and right, cable vault plate closely cooperate mutually, and structure is simple, easy accessibility, dependable performance, ensure that the personal safety of operating personnel, reduces production cost.
2, cable vault is provided with pressure release passage, once there is arcing accident, strong gas pressure can be allowed successfully to discharge housing.
3, be provided with stiffener inside rear plate, can allow pressure release time the impact of strong gas pressure on rear be reduced to minimum.
4, the existence of earthing device ensure that the reliable ground of fault current.
