Description
Technical field
The utility model relates to electronic technology field, is specifically related to a kind of thermostatic drying chamber single-phase AC solid-state relay control system.
Background technology
Baking oven is to utilize the heating of heating wire interlayer to make the equipment of object drying.It is applicable to than the baking and banking up with earth of room temperature high 5 ~ 300 ℃ (what have is high 200 ℃) scope, drying, thermal treatment etc., sensitivity is generally ± and 1 ℃.The model of baking oven is a lot, but basic structure is similar, generally is made up of casing, electric heating system and automatic temperature control system three parts.Baking oven is in the market heated and is all controlled by A.C. contactor, because A.C. contactor is chattering type, the contact is fragile.Original-pack on traditional equipment because of the control of A.C. contactor chattering type, disjunction is obvious, can bear certain temperature with A.C. contactor control constant temperature, but normal serviceable life is not as exchanging the normal long service life of control ac solid relay.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, the thermostatic drying chamber single-phase AC solid-state relay control system of long service life.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of thermostatic drying chamber single-phase AC solid-state relay control system, comprise the digital display temperature controller, single-phase AC solid-state relay (SSR60AA) and supporting M type heat radiator, described digital display temperature controller is connected with sensor, it is characterized in that: described M type heat radiator is connected with the assembling of single-phase AC solid-state relay, described M type heat radiator and single-phase AC solid-state relay are fixed on the back plate that easily dispels the heat thermostatic drying chamber electrical equipment control chamber, described digital display temperature controller " phase; in " termination AC220V power supply, wherein the middle phase line of power supply links to each other with digital display temperature controller " always " end, the 3rd end of the solid-state device that continues of described digital display temperature controller " low " termination single-phase AC, the 4th end of the solid-state device that continues of described single-phase AC and digital display temperature controller " in " end is connected, on the live wire of the 2nd termination power of the solid-state device that continues of described single-phase AC, the 1st end of the solid-state device that continues of described single-phase AC connects on the zero line of power supply through load.
The beneficial effects of the utility model are: the utility model adopts when exchanging the single-phase solid-state relay control of control interchange constant temperature, be more than hundred times of A.C. contactor normal serviceable life, and attonity noise, attonity spark, shatter-proof, anti-physical shock, reaction is fast, fiduciary level is high, have good moistureproof and mildewproof Anticorrosive Character, after changing, make the equipment overall performance stable, plant factor improves, and production cost reduces, and workman's efficiency improves.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of thermostatic drying chamber single-phase AC solid-state relay control system, comprise the digital display temperature controller, single-phase AC solid-state relay (SSR60AA) and supporting M type heat radiator, the digital display temperature controller is connected with sensor, M type heat radiator is connected with the assembling of single-phase AC solid-state relay, M type heat radiator and single-phase AC solid-state relay are fixed on the back plate that easily dispels the heat thermostatic drying chamber electrical equipment control chamber, the digital display temperature controller " phase; in " termination AC220V power supply, wherein the middle phase line of power supply links to each other with digital display temperature controller " always " end, the 3rd end of the solid-state device that continues of digital display temperature controller " low " termination single-phase AC, the 4th end of the solid-state device that continues of single-phase AC and digital display temperature controller " in " end is connected, on the live wire of the 2nd termination power of the solid-state device that continues of single-phase AC, the 1st end of the solid-state device that continues of single-phase AC connects on the zero line of power supply through load.
After the repacking, the temperature sensor input signal is to temperature controller, when not reaching design temperature as if temperature, " total, the low " end of often making war on the temperature controller still is closure state, making solid-state relay SSR60AA interchange control end 3,4 ends is 220V voltage, 1,2 end conductings, and thermostatic drying chamber continues heating; When reaching design temperature, " total, the low " end of often making war on the temperature controller is off-state, makes the ac solid relay control end not have 220V to exchange control voltage, solid-state relay 1,2 not conductings of end, thus thermostatic drying chamber is not heated, be in keeping warm mode.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
