Description
Technical field
The utility model relates to technical field of electric power, particularly relates to a kind of arcing protection cabinet.
Background technology
In actual use, due to the existence that unpredictable short trouble is possible, likely can be short-circuited arcing accident, gently then damages equipment for middle pressure and high-voltage ring network switch cabinet, heavy then damage whole looped network node and produce casualties.
Utility model content
Utility model object: the purpose of this utility model is to solve above the deficiencies in the prior art, provides a kind of arcing protection cabinet.
Technical scheme: a kind of arcing protection cabinet described in the utility model, described ring main unit casing join operation mechanism, described operating mechanism is provided with interlocking push rod, described operating mechanism is provided with lifting button, described operating mechanism bottom coupling mechanism dead bolt, described mechanism dead bolt conflict door-plate dead bolt, described door-plate dead bolt connects lower door-plate top, described lower door-plate and cable vault's conjunction plane are provided with lower front tooth, described lower front tooth fastens cable vault, vertical clapboard behind cable vault is provided with between described cable vault and pressure releasing chamber, described pressure releasing chamber lower openings, behind described cable vault, vertical clapboard has the unidirectional relief hole of pressure release backward, described pressure releasing chamber rear portion is provided with pressure releasing chamber rear shrouding, described pressure releasing chamber and described ring main unit casing connection place are provided with pressure release module.
Wherein, behind described cable vault, vertical clapboard has the unidirectional relief hole of pressure release backward.
Wherein, the unidirectional pressure release of described relief hole, pressure release direction is from cable vault's pressure release to pressure releasing chamber.
Beneficial effect: a kind of arcing protection cabinet described in the utility model, structure is simple, is convenient to manufacture and safe and reliable, is applicable to batch micro operations and can economical operation, can reduce equipment loss and personnel's injury that arcing fault causes to greatest extent.
Accompanying drawing explanation
Fig. 1 is the structural representation of cutaway view of the present utility model.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection range.
A kind of arcing protection cabinet as shown in Figure 1, comprise ring main unit casing 1, ring main unit casing 1 join operation mechanism 2, operating mechanism 2 is provided with interlocking push rod 8, operating mechanism 2 is provided with and promotes button 14, operating mechanism 2 bottom coupling mechanism dead bolt 10, mechanism's dead bolt 10 is conflicted door-plate dead bolt 9, door-plate dead bolt 9 connects lower door-plate 7 top, lower door-plate 7 is provided with lower front tooth 11 with cable vault 12 conjunction plane, lower front tooth 11 fastens cable vault 12, vertical clapboard 6 behind cable vault is provided with between cable vault 12 and pressure releasing chamber 4, behind cable vault, vertical clapboard 6 has the unidirectional relief hole 13 of pressure release backward, the unidirectional pressure release of relief hole 13, pressure release direction is from cable vault 12 pressure release to pressure releasing chamber 4.Pressure releasing chamber 4 rear portion is provided with pressure releasing chamber rear shrouding 5, and pressure releasing chamber 4 and ring main unit casing 1 connection place are provided with pressure release module 3.Behind cable vault, vertical clapboard 6 is installed straight down, before be cable vault 12, back is pressure releasing chamber 4.When there is arcing fault in cable vault 12, arcing gas by the unidirectional relief hole pressure release of pressure release backward that vertical clapboard behind cable vault 6 has to pressure releasing chamber 4.When arcing fault occurs ring main unit casing 1, arcing gases at high pressure wash pressure release module 3 open, pressure release to pressure releasing chamber 4, by the opening of pressure releasing chamber 4 bottom to cable trough pressure release.Lower door-plate 7 adopts hook structure, and lower door-plate 7 is first upwards mentioned just can open lower door-plate 7 afterwards, makes mechanism's dead bolt 10 and door-plate dead bolt 9 directly by the destruction of arcing impulsive force.The switch of operating mechanism 2 is when closing a floodgate with open position, and operating mechanism 2 interlocking push rod 8 withstands lower door-plate 7, and the lower door-plate 7 of prevention is carried; Switch is when earthing position, and interlocking push rod 8 is removed, and above promotes button 14, lower door-plate 7 ability is carried and opens; Play the door-plate dead bolt 9 that door-plate 7 is provided with, after under realizing, door-plate 7 is shut, the door-plate dead bolt 9 on lower door-plate 7 top heads into mechanism's dead bolt 10, and earthed switch could disconnect simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
