Description
Technical field
The utility model relates to high-tension apparatus manufacturing technology field, especially a kind of solid insulation ring main unit with pressure release passage.
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 pressure relief opening and pressure release passage guiding, expanding gas mainly, to the ejection of pull bar direction, when energy is larger, may cause breaking of insulated case and ring network cabinet body, thereby affect adjacent equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of solid insulation ring main unit with pressure release passage, and it can solve while the arcing fault occurring, the problem that may cause insulated case and ring network cabinet body to break.
In order to address the above problem, the technical solution adopted in the utility model is: this solid insulation ring main unit with pressure release passage, comprise cabinet, be provided with the mechanism driving chamber, mechanism controls chamber, switch gear room, cable vault and the bus-bar room that are formed by baffle for separating in described cabinet; Described switch gear room is below described mechanism driving chamber, described mechanism controls chamber is in a side of described mechanism driving chamber, described cable vault is below described mechanism controls chamber, described bus-bar room is below described switch gear room, in described switch gear room, insulated case is housed, described insulated case is provided with pressure relief opening, below described pressure relief opening, between described bus-bar room and described cable vault, is provided with pressure release passage; Be provided with right door on the dividing plate of the described cable vault of described pressure release passage one side, with it, on the dividing plate of the corresponding described bus-bar room of opposite side, be provided with left-hand door.
In technique scheme, more specifically scheme can also be: described insulated case, comprise casing, and 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 and pressure release passage, thus insulated case when running into arcing, expanding gas can be discharged insulated case from pressure relief opening, then from pressure releasing passages, discharges ring main unit, has avoided breaking of insulated case and ring main unit, can not affect neighbouring device.
