Description
Technical field
The utility model is related to convection current dehumidification system in a kind of terminal box, belongs to power equipment exhaust dehumidifying technology field.
Background technology
At present in power system, the terminal box of outdoor conventional equipment have above and below two steam vents and only one of which electric heating
Plate, is heated and is dehumidified using electric hot plate, in order to prevent the dirty entrance terminal box of rainwater, and the steam vent of design carries back bending,
And eyelet only has 3cm or so, after electric heating heating, the globule becomes vapor, and only fraction discharges terminal box by steam vent,
It is other to secondary line at the top of terminal box or inside terminal box and to operate a switch, form condensation, not only the secondary wire terminal to terminal box and
Operate a switch corrosion mouldization, also easily causes secondary line short circuit, potential safety hazard is caused to operation.So we arrange for such a humid air
A kind of terminal box convection current exhaust dehumidification system of the case study do not gone out, can play and be dried in holding terminal box, it is to avoid tide
Humid air eliminates the potential safety hazard in terminal box to secondary wire terminal in terminal box and the corrosiveness operated a switch.
Utility model content
The purpose of this utility model is to provide convection current dehumidification system in a kind of terminal box, when the humidity in terminal box is too high
When, humidity sensing element starts electric heating and heated, while starting fan, to being dehumidified in terminal box, keeps dry in terminal box
It is dry, it is to avoid terminal box in secondary line and the corrosion that operates a switch or short circuit, eliminate electrical equipment safe operation hidden danger, improve confession
The reliability of electricity, solves the above mentioned problem that background technology is present.
The technical solution of the utility model is：
Convection current dehumidification system in a kind of terminal box, comprising humidity conditioner, electric hot plate, lower convection current air exhausting device, upper right
Air exhausting device, upper humidity sensor, lower humidity sensor and terminal box are flowed, the lower convection current air exhausting device includes air inlet swan neck
Road and lower convection fan, air inlet elbow pipeline are arranged on the bottom of terminal box, and lower convection fan is arranged on air inlet elbow pipeline,
Upper convection current air exhausting device includes outlet elbow pipeline and upper convection fan, and outlet elbow pipeline is arranged on the top of terminal box, on
Convection fan is arranged on outlet elbow pipeline, and humidity conditioner, electric hot plate, upper humidity sensor and lower humidity sensor are equal
Be arranged in terminal box, lower convection fan, upper convection fan, electric hot plate, upper humidity sensor and lower humidity sensor with it is wet
Spend control device connection.
The upper humidity sensor is arranged on away from 10cm at the top of terminal box.
The lower humidity sensor is arranged at away from terminal box bottom 10cm, and the electric hot plate is arranged in terminal box bottom
Entreat position.Air inlet elbow pipeline and outlet the elbow pipeline is bent in 90 degree, air inlet elbow pipeline and outlet elbow pipeline
Bending direction is towards ground.
The width of the electric hot plate is the 1/2 of terminal box body width.
Good effect of the present utility model：On the basis of former terminal box heating and dehumidifying system, improving former electric hot plate can only office
The problem of the problem of portion's heating problems and a heating are not vented or portion discharge can not meet humid air in discharge terminal box, increases
Plus a humidity detection point and increase can produce the wind apparatus system of convection current wind, overcome at the top of terminal box or be internally formed condensation
The problem of, it is to avoid the secondary wire terminal of terminal box and operate a switch and corrosion mouldization and cause secondary line short circuit to cause hidden safely to operation
Suffer from.
