Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Structure circuit of the present utility model as shown in Figure 1.Comprise a temperature controller, the contact of temperature controller is ground connection 1., 2. contact connects 220VAC zero line, contact and 3. connects 220VAC live wire, (15), (16) input contact connects the both positive and negative polarity of temperature sensor, output contact 7., 8. for often opening, 7. contact connects 220VAC live wire, and 8. contact connects auxiliary reclay JZ1 one end, and the auxiliary reclay JZ1 other end connects 220VAC zero line.On the live wire of 220VAC and zero line, power switch is installed, on 220VAC live wire, fuse is installed.
Two ends after A.C. contactor J1 connects with the normally closed contact JZ1-1 of auxiliary reclay JZ1 are connected 220VAC.Two ends after A.C. contactor J2 connects with the normally closed contact JZ1-2 of start button NQ, X button NT, auxiliary reclay are connected 220VAC.The main contact of often opening of A.C. contactor J1 is connected with Automatic-heating group.The main contact of often opening of the second A.C. contactor J2 is connected with manual Fast Heating group.Automatic-heating group, manual Fast Heating group are 3～5KVA three-phase electric heater, phase line A, B, C Y-connection, O connecting to neutral line.
The second A.C. contactor J2 has two and often opens auxiliary contact J2-1, J2-2, often opens auxiliary contact J2-1 in parallel with start button NQ, for starting protection.Often open auxiliary contact J2-2 and be connected 220VAC with the two ends after pilot lamp DX series connection, for indicating when manually Fast Heating group is worked.
It is indoor that temperature sensor, Automatic-heating group and manual Fast Heating group are placed on high temperature ageing, and temperature controller and relay logic control combination are assemblied in control box.
Below sketch the course of work of the present utility model and principle:
When power switch K is closed, thermostatically-controlled equipment devotes oneself to work.Owing to starting under room temperature state, the temperature of the temperature sensor that temperature controller detects does not reach thermostatic control set-point, thereby the output contact of temperature controller 7., 8. two ends are in normally open, auxiliary reclay JZ1 is failure to actuate, its normally closed contact JZ1-1 is in closure state, thereby A.C. contactor J1 adhesive is moved, Automatic-heating group energising work.
In order to accelerate the rising of aging indoor temperature, now can, by pressing start button NQ, manual Fast Heating group be devoted oneself to work.When pressing start button NQ, A.C. contactor J2 adhesive action, manually Fast Heating group energising work.When manually Fast Heating group is worked, can stop its work by pressing X button NT.Certainly under normal conditions, without such operation, because when aging chamber temperature reaches thermostatic control set-point, system can be closed manual Fast Heating group automatically.
When aging indoor temperature reaches thermostatic control set-point scope, the output contact of temperature controller 7., 8. two ends are closed, and auxiliary reclay JZ1 moves adhesive, and its normally closed contact JZ1-1 cut-offs, thereby making A.C. contactor J1 discharge disconnection, the power-off of Automatic-heating group stops heating.Meanwhile, its another normally closed contact JZ1-2 also cut-offs, and makes A.C. contactor J2 also discharge and disconnect simultaneously, and manual Fast Heating group also power-off stops heating.
When well heater stops heating, aging chamber temperature through progressively declining after a while, during lower than thermostatic control set-point scope, the output contact of temperature controller 7., 8. two ends return again normally open, thereby make again A.C. contactor J1 adhesive action, the heating of again switching on of Automatic-heating group.Go round and begin again like this, complete automatic control and the adjusting of thermostatically-controlled equipment to aging indoor temperature.
It is worthy of note, the temperature control in aging chamber once reaches thermostatic control set-point scope, and the power-off of manual heating group stops after heating, and it has just exited control operation, no longer because room temperature reduces task again.Unless pressed start button NQ, could force its energising heating.Process like this and meet system control requirement, and it is more accurate that temperature is controlled.
The utility model can reach the control accuracy of aging indoor temperature: control set-point ± 1 ℃.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite that does not depart from spirit of the present utility model and design, within all should thinking and being included in protection domain of the present utility model.
