Description
Technical field
The present invention relates to a kind of transformer station temperature and humidity control device.
Background technology
In order to ensure that in hyperbaric chamber, converting equipment operating ambient temperature is suitable for, exhaust fan uses in a large number in transformer station.The exhaust fan automatic control box of current use, only possesses temperature regulating action, and poor sensitivity.After blower fan puts into operation, be in running status for a long time, greatly reduce serviceable life.In addition, run in reality at converting equipment, there is hyperbaric chamber humidity excessive, high-tension apparatus is condensation in middle-placed switch cabinet kind equipment cabinet particularly, and the equipment that affects normally runs the problem even broken down.
Summary of the invention
For the deficiency in solving the problems of the technologies described above, the object of the invention is to: provide one can overcome above-mentioned defect, can in main regulation hyperbaric chamber transformer station's temperature and humidity control device of transformer station's environment condition.
Transformer station provided by the present invention temperature and humidity control device comprises temperature sensor, humidity sensor, exhaust fan, air intake blower fan and control box, control box is arranged in transformer station, temperature sensor and humidity sensor are by data line connection control case, and exhaust fan and air intake blower fan are controlled by control box; Have treating apparatus in described control box, treating apparatus connects temperature sensor and humidity sensor, and treating apparatus connects air intake blower fan and exhaust fan by relay.
Described treating apparatus external-connection displayer.
Be provided with power supply in described control box, power supply connects the start-up circuit of exhaust fan and air intake blower fan by miniature circuit breaker.The safeguard measure such as protection circuit, fusible link conventional is at present substituted, for extending the serviceable life of blower fan by miniature circuit breaker.
Described temperature sensor is outer to be encapsulated by stainless-steel tube.Encapsulated by stainless-steel tube, namely do not affect the accuracy of thermometric, can water temperature be detected again.
Described humidity sensor is outer to be encapsulated by PE sintered filter core.Can effective filter dust, increase the service life.
The external audible-visual annunciator of described treating apparatus.
Compared with prior art, the present invention has following beneficial effect:
Rational in infrastructure, easy to use, can ambient conditions in Real-Time Monitoring transformer station, the duty of rational allocation blower fan, ensures serviceable life to greatest extent.
Accompanying drawing explanation
Fig. 1 structural representation of the present invention;
Fig. 2 frame principle figure of the present invention;
In figure: 1, humidity sensor; 2, temperature sensor; 3, control box; 4, exhaust fan; 5, air intake blower fan.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described further:
Transformer station's temperature and humidity control device as shown in Figure 1 comprises temperature sensor 2, humidity sensor 1, exhaust fan 4, air intake blower fan 5 and control box 3, control box 3 is arranged in transformer station, temperature sensor 2 and humidity sensor 1 are by data line connection control case 3, and exhaust fan 4 and air intake blower fan 5 are controlled by control box 3; Have treating apparatus in described control box 3, treating apparatus connects temperature sensor and humidity sensor, and treating apparatus connects air intake blower fan and exhaust fan by relay.
Two-way humidity sensor and a road temperature sensor, by 20 meters of long data line connection handling devices, freely can be placed on each corner in transformer station, conduct monitoring at all levels environmental data, and wherein a road humidity sensor is for monitoring outdoor humidity.Temperature sensor 1 is outer to be encapsulated by stainless-steel tube.Encapsulated by stainless-steel tube, namely do not affect the accuracy of thermometric, can water temperature be detected again.Humidity sensor is outer to be encapsulated by PE sintered filter core.Can effective filter dust, increase the service life.
Treating apparatus external-connection displayer.Can Real-Time Monitoring, convenient maintenance, early warning.
Be provided with power supply in control box, power supply connects the start-up circuit of exhaust fan and air intake blower fan by miniature circuit breaker.The safeguard measure such as protection circuit, fusible link conventional is at present substituted, for extending the serviceable life of blower fan by miniature circuit breaker.
In use, Temperature Humidity Sensor monitors the humiture situation in transformer station in real time, and there is a road humidity sensor for the humidity condition outside measuring chamber, when under environment at 70%RH of the humidity of outdoor, treating apparatus continues ventilation work by Control air intake blower fan and air-out blower fan, in lasting scavenging period, every 6 hours 6.5 minutes, exhaust fan gaps, air intake blower fan interval after 1.5 minutes, then continues to run, for improving serviceable life.
The outer burden filter screen of air intake blower fan, filters foreign material.
If humidity sensor detects that outdoor humidity is greater than 80%RH, treating apparatus, by cut-off blower fan, stops ventilation operation.
When the humidity in transformer station exceeds the threshold of power transformation station equipment, reported to the police by audible-visual annunciator, remind and manually dehumidify, proterctive equipment safety.
Treating apparatus carries out data interaction by RS485 interface and host computer, can remote real-time monitoring data.
