Description
The application is Application No. 200910233682.X, filing date on October 28th, 2009, and invention and created name is the divisional application of the application for a patent for invention of " humidity in transformer substation terminal box controls and display device ".
Technical field
The invention belongs to electronic technology field, be that a kind of humidity in transformer substation terminal box controls and display device.
Background technology
Quality and the using effect of terminal box of substation are the most affected by humidity.The high humility of the too high particularly plum rain season of humidity can have a strong impact on the quality of terminal box of substation, using effect and service life.
Summary of the invention
It is an object of the invention to provide a kind of humidity in transformer substation terminal box that can automatically control humidity in transformer substation terminal box timely acoustic-optic indicator case humidity exception to control and display device.
The technical scheme is that a kind of humidity in transformer substation terminal box controls and display device.The input of transformator T connects with 220V alternating current, and the input of transformator T has on and off switch K.The outfan of transformator T connects with the input of bridge rectifier D1-D4.The outfan of bridge rectifier is connected with display lamp La and filter capacitor C1.The two end bridgings of filter capacitor C1 have the current-limiting resistance R and electric capacity C2 being connected in series.Two ends of filter capacitor C1 also bridge the humid control assembly WK and relay J being connected in series.The one end of display being made up of display lamp Lb and loudspeaker S being connected in series is connected with the negative pole of alternating current power supply, and the other end is connected with the positive pole of alternating current power supply through the normally-closed contact J1 of relay J.Display lamp Lc and one end of dehumidifier DSP of being connected in series are connected with the negative pole of alternating current power supply, and the other end is connected with the positive pole of alternating current power supply through the normally-closed contact J2 of relay J.
Described humid control assembly WK be commercially available on market by humidity sensor, humidity set device assembly together with humid control switch combination.
Described display is the acousto-optic annunciator being made up of light emitting diode and loudspeaker being commercially available on market.
Described dehumidifier is the heater or moisture separator being commercially available on market.
Work process and the principle of the present invention be: turns on the power switch K, 220V alternating current after transformator T, bridge rectifier D1-D4 and capacitor C1, C2 and resistance R transformation, rectification, filtering low-voltage DC for humid control assembly S and relay J, simultaneously display lamp La luminescence.The humidity sensor sampling of humid control assembly S obtains humidity in transformer substation terminal box value.This humidity value compares with the setting value of the humidity set device of humid control assembly S automatically, and when being less than the setting value in humidity set device such as case endogenous dampness angle value, humid control switch is failure to actuate and is closed；During such as case endogenous dampness angle value higher than setting value in humidity set device, humid control switch motion and be in open mode.When humid control switch is opened, power on makes relay J turn on, and while relay J conducting, the normally-closed contact J1 and normally-closed contact J2 of relay J also simultaneously turn on.Making the display lamp Lc and the dehumidifier that connect with 220V alternating current obtain electric after normally-closed contact J1 conducting, now display lamp Lc is luminous, and dehumidifier dehumidifies.When case humidity falls below setting value, humidity sensor sampling obtains humidity in transformer substation terminal box value, and humid control switch can be indicated after comparing with the setting value in humidity set device to close.Open the light relay J after closedown, normally-closed contact J1 and the equal dead electricity of normally-closed contact J2 of humid control disconnects.So display lamp Lb, display lamp Lc, loudspeaker and dehumidifier all quit work.K can be turned off the power switch as the long period is not required to dehumidifying.
It is an advantage of the present invention to provide a kind of humidity in transformer substation terminal box that can automatically control humidity in transformer substation terminal box timely acoustic-optic indicator case humidity exception to control and display device.
