Description
Technical Field
The utility model relates to a secondary cell, in particular to a secondary cell of a high-voltage ring main unit.
Background
The conventional high-voltage ring main unit is characterized in that various inter-cabinet connecting lines exist between the secondary small chamber and the mechanism chamber, so that the top and the side of the secondary small chamber are provided with threading holes, the conventional high-voltage ring main unit is thoroughly sealed without any method, and runs in a humid environment for a long time, particularly, condensation is easily formed inside the box body when the temperature is reduced and the humidity is high, formed water drops can be attached to metal and plastic parts inside the high-voltage ring main unit, the condensation formed on a secondary wiring terminal row in the secondary small chamber can corrode metal conducting parts on the terminal row, AC/DC short circuit grounding is easy to cause, more serious condensation can cause short circuit between two secondary lines on the terminal row, and if the secondary wiring terminal row just happens to be a switch tripping circuit, switch misoperation can be immediately caused, and power failure accidents are caused.
The condensation that forms on the switch operating mechanism can corrode the metal parts in the mechanism, reduces the insulating property of insulating parts, can lead to creepage or flashover phenomenon, even causes the mechanism to block because of the corrosion, leads to earthing switch or isolator to construct to move in place when deciliter, if consequently make switch sound contact divide slowly and shut, then can cause very big electric power accident, and especially the switch corrosion phenomenon can be more serious when not operating for a long time.
