Description
Technical field
The utility model relates to the silicon controlled leakage current test device, in particular, relates to the inner controllable silicon leak current detection device of a kind of soft starter.
Background technology
Along with development of modern industry; Increasing electrical equipment finds broad application; Replace traditional plant equipment to carry out in order production work efficiently; Soft starter is as the soft start of a kind of current collection machine, soft stop, light-load energy saving and the kinds of protect function novel motor control assembly in one, in electrical control use cashier's office in a shop also more and more widely.
Main components and parts controllable silicon in the soft starter, the silicon controlled quality is the performance of decision soft starter directly.Test silicon controlled quality all is to use the controllable silicon tester usually; The controllable silicon tester that uses at present can only be tested single controllable silicon; When testing, must take soft starter apart ability, again the controllable silicon of inside tested one by one for the controllable silicon that is contained in soft starter inside.So each test all will be taken soft starter apart; The detection mode that must adorn soft starter again after test finishes is given and is produced, debugging work brings great inconvenience; The manpower and materials of labor during detection also cause test period long, give to produce to debug and also bring very big difficulty.
The utility model content
The utility model technical matters to be solved is to realize the inner controllable silicon leak current detection device of a kind of soft starter quickly and easily.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of soft start leakage current test board; Comprise isolating switch, pressure regulator, reometer and contactor; The three-phase input end interface of soft starter to be detected connects three-phase electricity through pressure regulator and isolating switch successively, and its three-phase output end interface connects load through contactor 1KM, and described contactor 1KM bypass is in series with contactor, reometer.
The bypass of described contactor 1KM is provided with contactor 2KM and contactor 3KM, and is located at reometer two incoming ends respectively.
Described reometer is a milliampere level reometer.
Soft start leakage current test board also is provided with PLC, and described PLC is connected with soft starter to be checked with 3 contactors and by its break-make of preset program sequential control and start and stop.
The advantage of the utility model is that this monitor station is simple in structure, and manufacturing cost is relatively low, and the installation and measuring process is simple, quick, saves the production cycle, and compatible good, is applicable to different soft starters.
Description of drawings
Face the content of every width of cloth accompanying drawing expression in the utility model instructions and the mark among the figure down and make brief description:
Fig. 1 is the soft starter electrical block diagram;
Mark among the above-mentioned figure is: 1, isolating switch; 2, pressure regulator; 3, PLC; 4, soft starter; 5, reometer; 6, load; 7, contactor 1KM; 8, contactor 2KM; 9, contactor 3KM.
Embodiment
Can know referring to Fig. 1; Soft start leakage current test board mainly comprises isolating switch 1, pressure regulator 2, reometer 5, three contactors and PLC3; Wherein isolating switch 1 is imported the termination three-phase alternating current; Output termination pressure regulator 2, the output terminal reception of pressure regulator 2 detects the three-phase power input end interface of soft starter 4; Load 6 is a motor, and its triple-phase line and zero line detect the three-phase output end interface of soft starter 4 through contactor 1KM7 reception; Reometer 5 is a milliampere level reometer, and is parallelly connected with contactor 1KM7 after its two incoming end is connected with contactor 2KM8 and contactor 3KM9 respectively.Behind soft starter 4 access three-phase input and output end interfaces, can carry out testing through controlling 3 contacts and soft starter 4 break-makes and start and stop.
PLC3 is mainly used in the start and stop and the bypass switching of soft starter 4; Pressure regulator 2 is a kind of regulation voltage devices in the major loop that are installed in; Mainly be that soft starter 4 is started under the different voltages with different grade, thereby detect its soft start silicon controlled leakage current under the different voltages with different grade.
Concrete testing procedure is following:
On monitor station, insert soft starter 4 to be detected;
The isolating switch 1 that closes adds 380VAC voltage to the loop, regulates pressure regulator 2 and adds different voltages with different for soft starter 4 input ends, is implemented in different electric and depresses test soft starter leakage current;
PLC3 work, control contactor 1KM7 adhesive;
PLC3 control starts soft starter 4, after startup finishes, stops soft starter 4;
Contactor 1KM7 is broken off in PLC3 control;
PLC3 control adhesive contactor 2KM8 and contactor 3KM9;
Reometer 5 shows the numerical value of leakage current.
Detection mode is time saving and energy saving like this, significantly reduced the workload of test, and soft starter 4 is a kind of generally starting equipment, and the wiring in test board is the same, makes test board have very strong versatility, and it is very big convenient all to have brought for installation and production.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
