Abstract
The utility model discloses a control device used for detecting the right-wrong status of wiring of a compressor of an air conditioner. The control device used for detecting the right-wrong status of the wiring of the compressor of the air conditioner comprises an outdoor unit (2), a power supply (3), an alternating current (AC) contactor (4), a terminal block (5), a controller (6) and a current transformer (7), wherein a control coil (41) of the AC contactor is connected with the controller (6), a main contact (42) of the AC contactor is connected on a circuit between the power supply (3) and the terminal block (5) in series, a primary side (71) of the current transformer is connected on a circuit between the outdoor unit (2) and the terminal block (5) in series, and a secondary side (72) of the current transformer is connected with the controller (6). According to the control device, the current transformer is used for detecting currents in the circuits. When an unusually heavy current is detected, the controller controls the AC contactor to disconnect the main contact right away so as to disconnect the circuit between the terminal block and the power supply, and therefore damage to the compressor of the air conditioner is avoided.
Description
Technical field
The utility model relates to a kind of control device of correcting errors for detection of the compressor of air conditioner wiring, belongs to the quality detection apparatus in the air-conditioning production process.
Background technology
At present, air-conditioner uses single-phase alternating current, and the applicable power supply of its compressor of air conditioner also only is designed to single-phase alternating current.This compressor of air conditioner is by major-minor winding start-up and operation.
During the air-conditioning normal operation, should be by three connecting lines (being respectively live wire, zero line, ground wire) by on the binding post that correctly is sequentially connected to compressor of air conditioner.If be connected to three line order mistakes on the binding post of compressor of air conditioner, compressor of air conditioner will damage.
In the production process of air-conditioning, in a single day with three line wrongs of compressor of air conditioner, air-conditioning powers on when flowing into next production process the staff, compressor operation will damage after the regular hour, brings loss to production.
The utility model content
The utility model is to solve in the air-conditioning production process staff with the problem of three line wrongs of compressor of air conditioner.
For this reason, the utility model provides a kind of control device of correcting errors for detection of the compressor of air conditioner wiring, comprise off-premises station, controller, power supply, junction block, off-premises station is connected on the power supply through junction block, it is characterized in that: also comprise the A.C. contactor summation current transformer; The control coil of above-mentioned A.C. contactor is connected with controller, and the main contact of A.C. contactor is connected on the circuit between power supply and junction block; The primary side of above-mentioned current transformer is connected on the circuit between off-premises station and junction block, and the secondary side of current transformer is connected with controller.
When air-conditioning detects at production line, the indoor set unlatching of always switching on, off-premises station is connected on the power supply through junction block.If it is correct that three line orders on the binding post of compressor of air conditioner connect, the maximum current the when electric current after the normal startup of off-premises station can not surpass the air conditioner design.If three line order connection errors on the binding post of compressor of air conditioner, the electric current after off-premises station starts can increase unusually, the maximum current when being far longer than design.
After off-premises station started, control device of the present utility model was by electric current in the current transformer testing circuit.If after detecting unusual large electric current (maximum current when designing greater than air conditioner), controller is controlled at once A.C. contactor and is disconnected main contact, and circuit between junction block and power supply is disconnected, and has so just avoided the damage of compressor of air conditioner.Simultaneously, the staff on the production line can judge in time also whether the wiring of compressor of air conditioner is correct, thereby carries out next step proper operation.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
The structural representation of Fig. 1 control device that to be the utility model correct errors for detection of the compressor of air conditioner wiring;
Fig. 2 is the operational flowchart of control device shown in Figure 1.
The specific 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, the control device of correcting errors for detection of the compressor of air conditioner wiring of this enforcement comprises indoor set 1, off-premises station 2, power supply 3, A.C. contactor 4, junction block 5, controller 6, current transformer 7.Wherein, the control coil 41 of A.C. contactor 4 is connected with controller 6, and the main contact 42 of A.C. contactor 4 is connected on the circuit of 5 of power supply 3 and junction blocks; The primary side 71 of current transformer 7 is connected on the circuit of 5 of off-premises station 2 and junction blocks, and the secondary side 72 of current transformer 7 is connected with controller 6.
The concrete operations flow process of the control device of correcting errors for detection of the compressor of air conditioner wiring of this enforcement is as shown in Figure 2:
Step 1: initialize;
Step 2: air-conditioning start;
Step 3: open operation greater than 15 milliseconds? if not, controller 6 does not detect, and continues to wait for; If then enter next step;
Step 4: the current value that controller 6 detects on the connecting line by current transformer 7;
Does step 5: controller 6 judge that current value is greater than setting value? if not, then return step 4; If then enter next step;
Step 6: controller 6 control A.C. contactors 4 disconnect main contact 42;
Step 7: finish.
After air-conditioning is opened, indoor set 1 operation of always switching on.If three line order connection errors on the binding post of compressor of air conditioner, the electric current after off-premises station 2 starts can increase unusually.Controller 6 detects large electric current by current transformer 7, if this current value is greater than setting value (maximum current when designing such as air conditioner), controller 6 is just controlled A.C. contactor 4 main contact 42 is disconnected, and the power supply of off-premises station will disconnect like this, has avoided the compressor of air conditioner damage.Certainly, the error during for fear of compressor of air conditioner moment startup is provided with the rear time-delay of start about 15 milliseconds (can adjust this value according to compressor) and detects the electric current on the connecting line again.
More than be one of embodiment of the present utility model, for those skilled in the art, do not spend performing creative labour, on the basis of above-described embodiment, can do multiple variation, can realize the purpose of this utility model equally.But this variation obviously should be in the protection domain of claims of the present utility model.
