Abstract
The invention provides a humidity control and display device in a terminal box of a substation. The device is characterized in that a 220 V AC power supply is connected with a transformer T; the transformer T is connected with bridge rectifier circuits D1, D2, D3 and D4; the output terminal of a bridge rectifier circuit is respectively connected with an indicator light La and a filter capacitor C1; the two ends of the filter capacitor C1 are in cross-over connection with a current-limiting resistor R and a capacitor C2 which are connected in series and with a humidity control component WK and a relay J which are connected in series; one end of a serially-connected display is connected with the negative pole of the AC power supply, and the other end is connected with the positive pole of the AC power supply through a normally closed contact J1 of the relay J; and a serially-connected indicator light Lc and one end of a dehumidifier DSP are connected with the negative pole of the AC power supply, and the other end of the dehumidifier DSP is connected with the positive pole of the AC power supply through a normally closed contact J2 of the relay J. By adopting the invention, the humidity in the terminal box of the substation can be controlled automatically, and abnormal situation of humidity in the terminal box can be displayed through sound and light in time.
Description
Technical field
The invention belongs to electronic technology field, is that a kind of humidity in transformer substation terminal box is controlled and display device.
Background technology
The quality of terminal box of substation and result of use are subject to the impact of humidity.The high humility of the too high particularly plum rain season of humidity can have a strong impact on quality, result of use and the serviceable life of terminal box of substation.
Summary of the invention
The object of this invention is to provide a kind of abnormal humidity in transformer substation terminal box of the interior humidity of the also timely acoustic-optic indicator case of humidity in transformer substation terminal box of automatically controlling controls and display device.
Technical scheme of the present invention is: a kind of humidity in transformer substation terminal box is controlled and display device.The input end of transformer T and 220V alternating current join, and the input end of transformer T has power switch K.The input end of the output terminal of transformer T and bridge rectifier circuit D1-D4 joins.The output terminal of bridge rectifier circuit is connected with pilot lamp La and filter capacitor C1.Two end spaies of filter capacitor C1 are connected to current-limiting resistance R and the capacitor C 2 being connected in series.Two ends of filter capacitor C1 also cross-over connection have humidity Control Component WK and the relay J being connected in series.The one end of display being comprised of pilot lamp Lb and loudspeaker S and the negative pole of AC power that are connected in series are connected, and the other end is connected with the positive pole of AC power through the normally closed contact J1 of relay J.The pilot lamp Lc being connected in series and one end of dehumidifier DSP and the negative pole of AC power are connected, and the other end is connected with the positive pole of AC power through the normally closed contact J2 of relay J.
Described humidity Control Component WK is the assembly of being combined by humidity sensor, humidity setting apparatus and humidity gauge tap that can buy on market.
Described display is the acousto-optic annunciator being comprised of light emitting diode and loudspeaker that can buy on market.
Described dehumidifier is well heater or the moisture separator that can buy on market.
The course of work of the present invention and principle are: turn on the power switch K, 220V alternating current after transformer T, bridge rectifier circuit D1-D4 and capacitor C1, C2 and resistance R transformation, rectification, filtering low-voltage DC for humidity Control Component S and relay J, the while, pilot lamp La was luminous.The humidity sensor sampling of humidity Control Component S obtains humidity in transformer substation terminal box value.This humidity value automatically and the setting value comparison of the humidity setting apparatus of humidity Control Component S, as humidity value in case during lower than setting value in humidity setting apparatus, be failure to actuate and in closed condition by humidity gauge tap.As humidity value in case during higher than setting value in humidity setting apparatus, humidity gauge tap action and in open mode.When humidity gauge tap is opened, power connection makes relay J conducting, also conducting simultaneously of the normally closed contact J1 of relay J and normally closed contact J2 in the time of relay J conducting.After normally closed contact J1 conducting, make the pilot lamp Lb that joins with 220V alternating current and loudspeaker obtain electric, make pilot lamp Lb and loudspeaker sound and light alarm.After normally closed contact J2 conducting, make the pilot lamp Lc that joins with 220V alternating current and dehumidifier obtain electric, now pilot lamp Lc is luminous, dehumidifier dehumidifying.When in case, humidity is reduced to lower than setting value, humidity sensor sampling obtains humidity in transformer substation terminal box value, with humidity setting apparatus in setting value after can indicate humidity gauge tap to close.Humidity gauge tap is closed the equal dead electricity of rear relay J, normally closed contact J1 and normally closed contact J2 and is disconnected.Pilot lamp Lb, pilot lamp Lc, loudspeaker and dehumidifier all quit work like this.As the long period do not need dehumidifying can powered-down K switch.
Advantage of the present invention has been to provide a kind of abnormal humidity in transformer substation terminal box of the interior humidity of the also timely acoustic-optic indicator case of humidity in transformer substation terminal box of automatically controlling and has controlled and display device.
