The operation of power network.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the utility model one.
Specific embodiment
Explanation is further explained to the utility model with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model provides a kind of Polymeric Housed MOA, including composite sheath 1, be arranged on it is multiple
The core body in overcoat is closed, the upper connecting terminal 2 of composite sheath upper end is arranged on, is arranged on the lower connecting terminal of composite sheath lower end
3, also including a disconnector 4 and an insulating support 5；The upper end of the disconnector passes through described insulating support one end and lower terminals
Son connection；The lower end of the disconnector passes through a ground lead and ground wire（It is not drawn into figure）Or the connection of metallic circuit shaft tower；Institute
The insulating support other end is stated to be fixedly connected with overhead line structures；The core body includes zinc oxide resistance sheet post 6 and zinc oxide resistance sheet
The Top electrode 7 of post upper end connection and the bottom electrode 8 being connected with zinc oxide resistance sheet post lower end；Top electrode connects with upper connecting terminal
Connect, bottom electrode is connected with lower connecting terminal；The zinc oxide resistance sheet post outside is also arranged with an insulating sleeve 9；The insulation
A radio temperature sensor 10 is additionally provided between sleeve and composite sheath；Insulation full skirt is provided with outside the composite sheath.

The piece column length phase is run should in time replace arrester in high temperature environments.Set between insulating sleeve and composite sheath rather than directly setting
Put on zinc oxide resistance sheet post, be to prevent from damaging sensor when high current passes through on zinc oxide resistance sheet post.
The core body that core body of the present utility model is designed for overall package, the core body preparation technology of relatively winding design is simpler,
Compared with cartridge type design core stability more preferably.
When arrester in abnormal cases, the discharging gap between arrester and disconnector can produce stronger impact electricity
Stream, disconnector is the rapid Automatic-falling of meeting, ground lead is disengaged with ground connection automatically, and failure arrester is fast from network system
Speed is exited, it is ensured that uninterrupted power supply.
Adjust pad 11 is provided between the zinc oxide resistance sheet post and Top electrode or between bottom electrode.
Preferably, the core body is overcoating to be stamped an elastic insulating layer 12.Elastic insulating layer engineering thermoplastic's insulating materials
It is made, prevents from being made moist because of core body or the caused arrester exception of other pollutions.
Above-listed preferred embodiment, is further described to the purpose of this utility model, technical scheme and advantage,
Should be understood that and the foregoing is only preferred embodiment of the present utility model, be not used to limit the utility model, it is all
