Description
Technical field
The present invention relates to electrical power distribution switchgear technical field, be specifically related to ventilation drying type switch cubicle.
Background technology
Along with the development of electrical power distribution, the place particularly outdoor cabinet that the environmental condition such as plateau is bad, switchgear makes
Body self-heating cooking during with, the area that long-term humidity is bigger, is the reason that switchgear is aging and the current class that bears declines,
The technology of current similar switch cubicle is generally adopted by natural air heat radiation, high humidity and easily produces at electrically conductive position solidifying
Dew, makes safety can not be guaranteed.
In use, the life-span raises and the decline of exponentially power equipment with temperature.Affect its continuous service electric current because of
Element is more.Air-break heating, the relation that influences each other between air-break rated continuous current and ambient temperature
The most out in the cold, when working according to switchgear bringing onto load, can be the biggest by its electric current so that device temperature raises, and causes cabinet
Body internal temperature raises, and affects other electrical equipments further, especially can have a strong impact on its service life in summer, so not
The produced impact of its heating can be ignored.
Summary of the invention
The invention aims to provide ventilation drying type switch cubicle, it is simple, easy to make that it has principle, can be effective
Control switch cubicle in the feature such as humiture.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises switch cubicle
Main body a, fan b, temperature sensor c, humidity sensor d, HD-ZWSK-SX Series Intelligent digital display temperature and humidity controller, heater
E, switch cubicle main body is separately installed with a fan up and down, and temperature sensor and humidity sensor are arranged on back plate in switch cubicle
On, heater is arranged on left side in switch cubicle.
Described switch cubicle main body cabinet lower end has a rectangle cable to import and export g, and also lower end is provided with ventilating blind
Window f.
10 interfaces are had on described ventilation drying type switch cubicle HD-ZWSK-SX Series Intelligent digital display temperature and humidity controller,
Temperature sensor connects 1,2, and humidity sensor connects 3,4,5, and fan connects 7,8, and heater connects 6,8, is connected to 220V between 9,10
Working power.
The present invention has the advantage that:
1. this product is installed simple, and similar heating is not heated the renewal of Based Intelligent Control；
2. radiator (assembling position effect is good)；
4. after-sales service is simple and convenient；
The most simple to operate and automaticity is higher；
6, economical reliable, stability is strong.

Fig. 1 is present configuration schematic diagram.
Fig. 2 is that installation site schematic diagram fanned against the wind by cabinet of the present invention.
Fig. 3 is cabinet bottom surface structure schematic diagram of the present invention.
Fig. 4 is the present invention each electrical equipment connection diagram.
Detailed description of the invention
With reference to Fig. 1-4, it comprises switch cubicle main body a, fan b, temperature sensor c, humidity sensor d, HD-ZWSK-SX
Series Intelligent digital display temperature and humidity controller, heater e, switch cubicle main body is separately installed with a fan, temperature sensor up and down
Being arranged in switch cubicle in back plate with humidity sensor, heater is arranged on left side in switch cubicle.Described switch cubicle main body
Cabinet lower end has a rectangle cable to import and export g, and also lower end is provided with ventilation shutter f.Described ventilation drying type switch
Having 10 interfaces on cabinet HD-ZWSK-SX Series Intelligent digital display temperature and humidity controller, temperature sensor connects 1,2, and humidity sensor connects
3,4,5, fan connects 7,8, and heater connects 6,8, is connected to the working power of 220V between 9,10.
Fan design fills a fan and fan, temperature sensor and intelligent temperature and humidity control respectively on cabinet top and cabinet lower end
Device processed with the use of, this controller model is HD-ZWSK-SX Series Intelligent digital display temperature and humidity controller, and temperature controller is permissible
Setting maximum temperature value according to practical situation, control the start and stop of fan, the temperature in sensor detects cabinet is higher than setting
During fixed temperature value, by sensor to one enabling signal of controller, now normally opened between internal No. 7 and No. 8 of controller
The closing of contact makes the charged automatic startup of fan dispel the heat, and owing to fan is separately mounted to top and lower end, lower end fan is taken out outside cabinet
Cold wind in cabinet, the principle hot-air risen further according to hot-air can be flushed to more rapidly cabinet top, simultaneously the cabinet row of fanning against the wind
Wind, thus reach the effect lowered the temperature rapidly.
When temperature sensor detects that temperature drops to the temperature value set, stop letter by sensor to controller one
Number, now the normally opened contact between internal No. 7 and No. 8 of controller is opened, and fan dead electricity stops operating.
If this cabinet uses the humidity in humid area, environment relatively big, the humidity sensor acted in cabinet detects
Ambient air humidity, prevents in electrically conductive equipment surface, produces condensation, when the humidity in environment reaches in intelligent controller
During preset value, intelligent controller sends signal, by 6 on controller, 8 two Guan Bis, makes heating load form loop, completes to add
Heat, makes air in cabinet keep being dried, and disconnected except condensation generation, the detection temperature of temperature sensor simultaneously, being unlikely to is temperature mistake in cabinet
High.This principle completes circulation, is that in cabinet, the holding of air moment is dried, makes electrical equipment work under suitable operating temperature, very
In the good life-span maintaining switchgear, strengthen again this cabinet security performance in whole electrical system.
