Description
Technical field
The utility model is related to a kind of terminal box more particularly to a kind of heat-insulated terminal boxs of wood moulding.
Background technology
The terminal box that field of power transmission uses is mostly that metal makes（Such as stainless steel）, in high temperature and humidity area, in terminal box
Temperature significantly larger than environment temperature under daytime sunshine（Difference is reachable or more than 16 degree）, humidity is relatively low in case（60-70% is left
It is right）, evening terminal the temperature inside the box is down to almost the same with ambient temperature；Since evening environment temperature declines so that babinet
The unexpected decline of the temperature inside the box inside originally higher than environment temperature, moisture is influenced quickly to intrude into babinet by negative pressure in cable duct
It is interior, so that humidity in babinet is quickly increased（Up to 90% or more）So that the electronic product, electric appliance original paper in terminal box are by serious
It influences, causes the generation of electrical equipment defect.It is mainly manifested in lower several respects：
1, hyperthermia and superheating makes equipment have certain temperature due to internal loss, if ambient temperature is excessively high, or it is empty
Flow of air is poor, prevents the heat of equipment from scattering in time, equipment can be made due to mistake thermal tripping, or even burn out equipment, especially
Electronic product, electric appliance original paper in distribution box, terminal box will seriously affect the service life of product, also affect protection
The stability of device performance and the reliability of action and the accuracy of metering, the reactive-load compensation capacitor run at high temperature melt
Disconnected device also can shorten the service life.
2, air humidity（It makes moist）Air humidity is excessively high, reduces the dielectric strength of electrical equipment.On the one hand, switchgear
In many places by the air gap insulation, humidity is excessively high, and the insulation performance of air can be made to reduce；On the other hand, in air
Attachment of moisture on insulating materials surface, so that the insulation resistance of electrical equipment is reduced, especially with the longer equipment of the time limit, by
There are dust accumulation adsorption moisture, moist degree will be more serious in inside, insulation resistance is lower；The Leakage Current of equipment greatly increases, very
To insulation breakdown is caused, cause an accident.
3, mould wet air is conducive to the growth of mould.Practice have shown that when temperature is 25-30 degree, relative humidity is
When 75%-95%, it is the good condition of fungus growth, if the speed of growth of mould will be accelerated by drawing badly；Contain in mould
A large amount of moisture makes the insulation performance of equipment substantially reduce, and to some porous insulating materials, mould root can be deep into material
Insulation breakdown is caused in inside；The acidic materials gone out secreted by the metabolic process of mould interact with insulation, make apparatus insulated
Performance declines.
Case above, not only shortens the service life of product, while influencing stability and the action of protector performance
Reliability, and metering accuracy, cause security risk.

Existing common tainless terminal case is transformed into the wood moulding with inner cover and corrosion-and high-temp-resistant by the utility model
The double layers of terminals case of thermal insulation board outer cover.Using stainless steel inner cover, ensure that rainwater does not enter in terminal box, in stainless steel side tank wall
On be designed with vented exhaust mouth, install special wood moulding thermal insulation board outer cover, wood moulding thermal insulation board and stainless steel appearance outside stainless steel inner cover additional
Face vacantly connects, and ensures that stainless steel outer wall forms the circulation of air with wood moulding thermal insulation board inner wall.On the tank wall of stainless steel side
The moisture in case can be discharged through the bottom of box outside babinet through hanging wood moulding thermal insulation board exhaust passage for vented exhaust mouth；Bilayer is set
Meter, sunlight do not shine directly on terminal box inner cover, and condensation is avoided to generate.Fan and Temperature and Humidity Control can be installed additional in terminal box
Temperature, the humidity of temperature and humidity controller has been set as needed in device, and then fan starts.The utility model utilizes natural wind
Mobility reduce or shorten the temperature difference difference in change away from, prevent the generation of condensation, by isolation and ventilation, prevent moisture in cable duct
To the invasion inside terminal box, product in terminal box is protected, is prolonged the service life, reduces accident potential.
The beneficial effects of the utility model：The utility model have many advantages, such as it is simple in structure, be easy make, it is safe and practical,
It solves the problems, such as temperature shock in terminal box, reduces the humidity in terminal box, the air circulation of enhancing terminal box inside and outside, tool
There is the function of moisture-proof, anti-aging, mould proof, anti-corrosion, anti-unreliable, the anti-short circuit of contact.
