Arrange further: the region that described internal layer, support column and temperature reflecting layer are constituted is vacuum area.
It is arranged such, is reflected back the external world from extraneous heat major part by temperature reflecting layer, but also fraction is remaining
Temperature enter inside insulation crust, still easily cause the rising of temperature in pole under accumulation, and vacuum be heat insulation
Effect is the best, can avoid air circulation and the heat transfer that causes, and therefore the setting of vacuum area further enhances sealing
The heat resistance of pole and heat collecting property, strengthen its ageing resistance, makes insulation crust be less susceptible to cracking, extends the use of pole
Life-span.
Arrange further: being provided with cushion between described vacuum interrupter and internal layer, cushion is made up of silastic material.
Being arranged such, cushion can avoid directly contact of vacuum interrupter and internal layer, prevent stress excessive cause interior
The damage of layer, silastic material is nonpoisonous and tasteless, and relatively strong to the defensive ability/resistance ability of high temperature and severe cold, intensity and elasticity are splendid, therefore make
The cushion made with silastic material can promote resistance to elevated temperatures and the ageing resistance of pole further.
Arrange further: the cylinder of described insulation crust is provided with two connectors, and two connectors are respectively close to insulation
The top and bottom of shell and constitute the angle of 180 °, are provided with female thread, female thread direction and insulation crust post in connector
Body is parallel.
Being arranged such, threaded is more reliable connected mode, and two connectors are that 180 ° of angles can make sealing
The connection of pole is the most firm and stable, can pole two-layer all be fixed, and the use making pole is safer
And it is reliable.
As preferably, described insulation crust is provided with connection base towards lower floor's wire outlet seat side.
Being arranged such, connecting base is the connection with following wire outlet seat Yu switch, and connection assist fixes sealing
Pole, makes pole be less susceptible to generation and rocks.
Another object of the present utility model is to provide a kind of solid insulation ring main unit, and it has use safety, is difficult to aging
Advantage.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of solid insulation ring main unit, with above-mentioned pole.
In sum, this utility model has the advantages that
This pole is possible not only to avoid and extraneous air, contact with moisture, extends the use time of pole,
In the case of ambient temperature is higher, extraneous temperature can also be reflected to a certain extent, keep inside pole
Stablizing of temperature, prevents temperature in pole too high and causes the aging of insulation crust and cracking, make the use of pole
Safer.
