Background technology
In the prior art, the locomotive air conditioner system and device that uses in producer or the workshop usually is the product that is provided by a plurality of manufacturer, their structures all have nothing in common with each other, and the failure rate of air-conditioning power supply box wherein is also higher relatively, but often owing to there is not test experience equipment targetedly, cause some device to break down often, and be difficult to after the fault repair.
Existing pick-up unit all can only detect the air-conditioning power supply box of a manufacturer, and this just causes great difficulty to service work.And if when detecting the power supply box of other producer non-fault being arranged, but can't detect, can only change power supply box, but its cost is higher relatively about 50,000 yuan.If detect the power supply box of a plurality of producers, must purchase the checkout equipment that a plurality of manufacturers provide.This will certainly once add the detection cost widely and become to produce cost.
The utility model content
The purpose of this utility model is, overcomes the defective of above-mentioned prior art and provides a kind of different manufacturers air-conditioning power supply box that can detect not detect the air-conditioning power supply experiment table that air-conditioning system provides powerful guarantee.
For achieving the above object, the utility model is taked following design proposal:
A kind of air-conditioning power supply experiment table; comprise the protection Drive and Control Circuit that links to each other with the input power supply; described protection Drive and Control Circuit links to each other with voltage regulator control circuit by current rectifying and wave filtering circuit; this voltage regulator control circuit is connected with adjusts voltage display device and switching controller; described switching controller links to each other with the direct current output control circuit that is connected with the current/voltage display device; described direct current output control circuit links to each other with start-up circuit with terminal row by the aviation connector, and described start-up circuit links to each other with test block to be measured via the operating circuit and the refrigeration control circuit that ventilates.
Preferably, be connected with the input voltage display device on the described protection Drive and Control Circuit.
Preferably, described is 80～140V through the adjusted voltage of voltage regulator control circuit.Further, also be connected with first holding circuit between described start-up circuit and the operating circuit.Further described operating circuit links to each other with pilot lamp on the air-conditioning power supply experiment table.
Preferably: also be connected with information feedback display circuit, load circuit and second holding circuit in described test block position.
The utility model has the advantages that: the utility model can be by the characteristic and the total characteristic of each manufacturer production different product; detect power supply box whether input voltage is normally arranged; and whether the stable ac voltage of output is arranged after inversion, can protect the normal operation of air-conditioning unit thus better.Particularly, the utility model can guarantee to import under the stable situation of power supply, and whether measure has output voltage values and can detect trouble location apace.
Description of drawings
Fig. 1 is a circuit FB(flow block) of the present utility model.
Embodiment
Referring to Fig. 1; the preferred embodiment of a kind of air-conditioning power supply of the utility model shown in it experiment table; comprise the protection Drive and Control Circuit that links to each other with the input power supply; described input power supply is 220V; the alternating current of 50HZ; be connected with the input voltage display device on the described protection Drive and Control Circuit; this protection Drive and Control Circuit also links to each other with voltage regulator control circuit by current rectifying and wave filtering circuit; this voltage regulator control circuit is connected with adjusts voltage display device and switching controller; described switching controller links to each other with the direct current output control circuit that is connected with the current/voltage display device; described direct current output control circuit links to each other with start-up circuit with terminal row by the aviation connector, and described start-up circuit links to each other with test block to be measured via the operating circuit and the refrigeration control circuit that ventilates.
Preferably, the adjusted voltage of process voltage regulator control circuit described in the utility model is 80～140V.And, also be connected with first holding circuit between described start-up circuit and the operating circuit.Described operating circuit links to each other with pilot lamp on the air-conditioning power supply experiment table.
In addition, also be connected with information feedback display circuit, load circuit and second holding circuit in test block described in the utility model position.
Particularly, as shown in Figure 1, the course of work of a kind of air-conditioning power supply of the utility model experiment table is:
Input power supply 220V exchanges 50HZ; by the driving of protection driving circuit and after showing ac voltage on the input voltage display device; give current rectifying and wave filtering circuit and produce DC voltage; then to voltage regulator control circuit and show the required magnitude of voltage of pressure regulation (80～140V), send stable electric current and voltage by switching controller again and be presented on the current/voltage display device.Afterwards; deliver to the experiment instruction by aviation connector, terminal row; start-up circuit starts operating circuit and shows that the pairing pilot lamp of each feature operation is bright; through the refrigeration control circuit that ventilates; select to test specimen (air-conditioning power supply box); normally whether the testing state; simultaneously tested information is shown by the information feedback display circuit; phase place, voltage between phases value (interchange) also are provided with second holding circuit; when the test specimen load abnormal has under-voltage, phase shortage, overcurrent; described second holding circuit stops automatic tripping to send to test specimen.
When testing for the power supply box of different manufacturers, can be according to the different parameters requirement, selector switch, aviation company's wiring realize the security and the accuracy of test block.
Load circuit can be powered by providing to the indoor and outdoor compressor with the corresponding output three-phase alternating current 380V of control circuit, load can be used two motors of 380V/0.37KW, detect the power supply box load capacity, and can detect the duty of air-conditioning control box, maneuver box simultaneously.
