Abstract
The utility model belongs to the field of variable frequency compressor parameter detection, in particular to an automatic detection device of a variable frequency compressor. The automatic detection device of the variable frequency compressor is portable, when the variable frequency air conditioner compressor can not normally operate, a user or a maintenance man can directly detect and obtain parameters of the compressor to be detected according to the portable automatic detection device, compare the parameters with a nominal value of compressors of the kind, determine whether the compressor is normal at the first time and further determine whether the variable frequency controller or the compressor needs to be replaced, and therefore work efficiency can be greatly improved, the situations that the damaged compressor is used and a new variable frequency controller is matched are avoided at the same time, and the new controller is prevented from being damaged again.
Description
Technical field
The utility model belongs to frequency-changeable compressor parameter detecting field, relates in particular to a kind of automatic measuring unit of frequency-changeable compressor.
Background technique
Can free adjustment due to frequency converting air-conditioner compressor frequency, compare invariable frequency compressor more energy-conservation, quiet and comfortable, therefore, the market share of frequency converting air conditioner climbs up and up in recent years.But then, compare with fixed frequency air conditioner, frequency converting air conditioner is due to the complexity of controlling, make to keep in repair more and more difficult: for example, when the compressor of transducer air conditioning can not turn round, may be the electronic parts and components damage in frequency-variable controller, may be also that frequency-changeable compressor itself damages, or both damage.At present, market maintenance man does not also have a kind of instrument or method to judge that quickly and accurately specifically which partly damages, conventionally be all the method by attempting: first change a new frequency-variable controller and control, if still can not run well and just frequency-changeable compressor also changed.But just there are several problems in such damage mode of looking into: the one, can not locate and where damage the end fast; The 2nd, if frequency-changeable compressor itself damages, when using new frequency-variable controller to drive, may damage new frequency-variable controller.
Model utility content
In view of this, the purpose of this utility model is just to provide a kind of automatic measuring unit of frequency-changeable compressor, is intended to solve the existing technical problem of looking into damage mode inefficiency and may again damaging frequency-variable controller.
To achieve these goals, the automatic measuring unit of the frequency-changeable compressor that the utility model provides, comprising:
For connecting the compressor interface unit of tested compressor;
According to the type of tested compressor, input, start to detect or stop the key-press input unit of sense command;
Show the type of tested compressor, corresponding nominal parameters, the testing result of reality and the display unit of whole device work state information;
Be connected with described compressor interface unit, key-press input unit, display unit respectively, according to the operational order of described key-press input unit, transfer corresponding nominal parameters, automatically detect the MCU controller of tested compressor parameters; And
Be connected with described MCU controller, give the PMU of whole device and tested compressor power supply.
Further, described key-press input unit comprises several buttons, and described button comprises that type of compressor selection key and start/stop detect button.
Further, described PMU comprises an overload protection module; Described overload protection module guarantees that the in the situation that of tested compressor corrupted whole device is not damaged.
Further, described display unit comprises a liquid crystal display panel.
Further, described PMU comprises:
Give the switch power module of described MCU controller and display unit power supply; And
Give the three-phase voltage forceful electric power module of described tested compressor power supply.
The automatic measuring unit of the frequency-changeable compressor that the utility model provides is mancarried device, after transducer air conditioning compressor can not run well, maintenance man can pass through this mancarried device at the scene, direct-detection and the parameters of obtaining compressor, in the very first time, confirm that whether compressor is normal, what further definite needs were changed is frequency-variable controller or compressor, thereby can greatly increase work efficiency, avoid using the compressor of corrupted to mate new frequency-variable controller simultaneously, thereby avoid again damaging new controller.
