Abstract
The invention discloses a sealing switch cabinet capable of preventing condensation. The sealing switch cabinet capable of preventing condensation comprises a switch cabinet body, wherein a temperature-outside-cabinet sensor is connected outside the switch cabinet body, a temperature-inside-cabinet sensor, a humidity sensor and an automatic heating dehumidification device are arranged inside the switch cabinet body, and a control and display device is arranged on a front panel of the switch cabinet body. Due to the adoption of the structure, the temperature-outside-cabinet sensor can be used for detecting the change of the environmental temperature outside the cabinet, the temperature-inside-cabinet sensor and the humidity sensor can be used for detecting the change of the temperature and the humidity inside the cabinet, and the control and display device can be used for automatically starting or closing the automatic heating dehumidification device without human intervention according to the differences of temperatures inside and outside the cabinet or the humidity data inside the cabinet before condensation happens. The sealing switch cabinet capable of preventing condensation is convenient to use, reliable and energy-saving.
Description
Technical field
The present invention relates to a kind of switch cubicle, particularly the anti-condensation enclosed switch cabinet of a kind of energy.
Background technology
The enclosed switch cabinet, after operation a period of time, because of poorly sealed, moisture or dust enter; The internal gas flow circulation is not smooth, and internal steam can not in time be discharged; Reasons such as the interior high humidity of plum rain season cabinet cause in-cabinet temperature to be lower than dew point temperature, form " condensation ", and the generation of " condensation " will influence the normal operation of switch cubicle, seriously also can cause accident.For preventing the harm that brings of condensation, present a kind of method commonly used is according to the startup of operational environment Artificial Control heater or closes that artificial dependence is big, and it is inconvenient to use, and reliability is low, closes heater if forget, and will bring the waste of the energy; Another kind method is that the condensation transducer is installed in switch cubicle, utilizes the condensation transducer to start automatically and closes heater, and this kind method is just to drive heater after condensation takes place, and simultaneously, the condensation transducer is insensitive to low humidity (being lower than 75%).
Summary of the invention
The technical problem to be solved in the present invention provides a kind of energy-conservation, reliable, easy to use, anti-condensation enclosed switch cabinet of energy that can drive heater before condensation be about to take place.
For solving the problems of the technologies described above, technical scheme provided by the invention is as follows:
The enclosed switch cabinet that a kind of energy is anti-condensation, comprise the switch cubicle body, described switch cubicle body exterior is connected with the outer temperature sensor of cabinet, the switch cubicle body interior is provided with in-cabinet temperature transducer, humidity sensor and automatic heating and dehumidification device, switch cubicle body front panel is provided with control and display unit, this control and display unit can be controlled the automatic startup of automatic heating and dehumidification device and close, can the inside and outside temperature of display case and difference, cabinet in humidity data.
Described switch cubicle bodies top center is provided with the heat radiation through hole, is provided with ventilation fan in this heat radiation through hole.
Be provided with detector in the described automatic heating and dehumidification device.
The present invention is owing to adopted said structure, the outer temperature sensor of cabinet can detecting box external environment variation of temperature, in-cabinet temperature transducer, humidity sensor can detect in-cabinet temperature, humidity changes, control and display unit can be according to humidity datas in cabinet internal and external temperature difference or the cabinet, before condensation does not also take place, can start automatically and close automatic heating and dehumidification device, not need artificial participation, easy to use, reliable.Automatically the heating and dehumidification device starts and the control on opportunity of closing makes the energy-saving and environmental protection more of this switch cubicle automatically.
Description of drawings
Fig. 1 is the structural representation of the enclosed switch cabinet that the present invention can be anti-condensation.
Wherein have: 1. switch cubicle body; 2. the outer temperature sensor of cabinet; 3. in-cabinet temperature transducer; 4. humidity sensor; 5. automatic heating and dehumidification device; 6. detector; 7. control and display unit; 8. heat radiation through hole; 9. ventilation fan.
Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the enclosed switch cabinet that a kind of energy provided by the invention is anti-condensation, comprise switch cubicle body 1, described switch cubicle body 1 is externally connected to the outer temperature sensor 2 of cabinet, switch cubicle body 1 inside is provided with in-cabinet temperature transducer 3, humidity sensor 4 and automatic heating and dehumidification device 5, switch cubicle body 1 front panel is provided with control and display unit 7, this control and display unit 7 can be controlled the automatic startup of automatic heating and dehumidification device 5 and close, can the inside and outside temperature of display case and difference, cabinet in humidity data.
The outer temperature sensor 2 of above-mentioned cabinet can detecting box external environment variation of temperature, in-cabinet temperature transducer 3, humidity sensor 4 can detect in-cabinet temperature, humidity changes, control and display unit 7 can be according to humidity datas in your internal and external temperature difference or the cabinet, before condensation does not also take place, can start automatically and close automatic heating and dehumidification device, do not need artificial participation, easy to use, reliable.
Described switch cubicle body 1 top center is provided with heat radiation through hole 8, is provided with ventilation fan 9 in this heat radiation through hole., heat radiation through hole 8 and ventilation fan 9 can be accelerated the circulation of air of switch cubicle inside, and hot gas or moisture are discharged in switch cubicle fast, have prevented the gathering of moisture.
Be provided with detector 6 in the described automatic heating and dehumidification device 5.Whether the detectable automatic heating and dehumidification device of this detector 65 operate as normal, if having unusually, with the alarm user maintenance, prevents because of heating and dehumidification device 5 unusual condensations that take place automatically.
The enclosed switch cabinet that above-mentioned energy is anti-condensation, wherein said automatic heating and dehumidification device 5 start automatically and preferred opportunity of closing has two kinds:
First kind: outside in-cabinet temperature is lower than cabinet, start automatically during 3 ℃ of temperature, close automatically when being higher than 3 ℃ of outer temperature of cabinet.
Second kind: when humidity in the cabinet starts during greater than 65RH automatically, close automatically when being lower than 50RH.
This kind method, but within ± 3 ℃, the humidity in the switch cubicle remains between the 50-65RH, in this temperature and low-humidity environment all the time for maintained switch in-cabinet temperature and cabinet external environment temperature gap, condensation will be difficult for forming, and the operation stability of switch cubicle is provided.
In the present embodiment, in-cabinet temperature transducer 3 is provided with one, and the user can arrange several corresponding temperature sensors at easy condensation position as required, in order to accurately detect, also belongs to the scope of protection of the invention.
