Abstract
The utility model discloses an insulating box with a pressure release port. The insulating box with the pressure release port relates to the high voltage equipment manufacture technology field, and comprises an insulating box body and an arc extinguish chamber insulating pull rod assembly arranged at one side in the box body. The arc extinguish chamber insulating pull rod assembly is connected with a movable terminal, and the movable terminal is communicated with a static contact seat in a soft connection manner. The static contact seat is connected with an isolating pull rod assembly arranged at the other side in the box body, and the bottom of the box body is equipped with the pressure release port. One side of the pressure release port is equipped with a melting chamber pressure release aluminum ring, and the outer side of the melting chamber pressure release aluminum ring is equipped with an O-shaped seal ring. The melting chamber pressure release aluminum ring and the O-shaped seal ring are connected with one side of a melting chamber pressure release sheet, and the other side of the melting chamber pressure release sheet is connected with a melting chamber pressure release flange. The insulating box with the pressure release port can solve the harm brought by the expansion of a gas in the insulating box when an arcing fault occurs.
Description
Technical field
The utility model relates to high-tension apparatus manufacturing technology field, especially a kind of insulated case with pressure relief opening.
Background technology
At present, ring main unit is more and more general in the application of distribution system, and insulated case is as a critical piece in ring main unit, and can the quality of its quality directly affect ring main unit and normally use.When existing insulated case structure is not all considered the arcing fault to occur, the harm that in insulated case, gas expansion brings.Insulated case is when running into arcing, in the situation that there is no the pressure relief opening guiding, expanding gas mainly, to the ejection of pull bar direction, when energy is larger, may cause insulated case to be broken, thereby affect adjacent equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of insulated case with pressure relief opening, and it can solve while the arcing fault occurring, the problem of the harm that in insulated case, gas expansion brings.
In order to address the above problem, the technical solution adopted in the utility model is: this insulated case with pressure relief opening, comprise the insulated case casing, be arranged on the arc control device insulated tension pole assembling of a side in described casing, described arc control device insulated tension pole assembling and moved end sub-connection, described moved end is communicated with static contact seat by being flexible coupling; Described static contact seat and the isolation pull bar assembly connection that is arranged on opposite side in described casing, bottom at described casing is provided with pressure relief opening, one side of this pressure relief opening is provided with molten storehouse pressure release aluminium ring, the outside of described molten storehouse pressure release aluminium ring is provided with the O RunddichtringO, described molten storehouse pressure release aluminium ring is connected with a side of molten storehouse pressure release thin plate with described O RunddichtringO, and the opposite side of described molten storehouse pressure release thin plate is connected with molten storehouse pressure relief flange.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect had is the utility model:
Owing to being provided with pressure relief opening, thus insulated case when running into arcing, expanding gas can be discharged insulated case from pressure relief opening, has avoided breaking of insulated case, can not affect neighbouring device.
The accompanying drawing explanation
Fig. 1 is the structural representation with the insulated case of pressure relief opening.
Fig. 2 is the partial enlarged drawing at Figure 1A place.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
The insulated case with pressure relief opening of Fig. 1, an end and double threaded screw 1 one who is contained in the arc control device insulated tension pole assembling 2 of insulated case casing 12 1 sides is connected, the other end of double threaded screw 1 is stretched out outside casing 12 and is connected with external equipment, the other end of arc control device insulated tension pole assembling 2 is connected with 5 the end of being flexible coupling by moved end double threaded screw 7 and moved end sub 6, and 5 the other end of being flexible coupling is connected with static contact seat 11; An end that is contained in the isolation pull bar assembling 21 of insulated case casing 12 opposite sides stretches out outside casing 12 and is connected with external equipment, and its other end is connected with connecting lever pin 19 and movable contact assembling 18, and an end of movable contact assembling 18 is connected with moving knife; One end of moving knife is connected with static contact seat 11, and the other end of moving knife is connected with contact rod with moving knife set bolt 14; On the sidewall of casing 12 and contact rod the same side, be fixed with side joint ground static contact seat 13 with bolt, for reliable ground; Be provided with pressure relief opening below side joint ground static contact seat 13, under normal circumstances, for pressure relief opening, molten storehouse pressure release aluminium ring 26, O RunddichtringO 27, molten storehouse pressure release thin plate 25 and molten storehouse pressure relief flange 24 seal, when the arcing fault occurs when, expanding gas breaks through the blockade of molten storehouse pressure release aluminium ring 26, O RunddichtringO 27, molten storehouse pressure release thin plate 25 and molten storehouse pressure relief flange 24 discharges from pressure relief opening, avoids accident further to enlarge.
