Description
Technical field
The utility model relates to a kind of current signal generator for the debugging of boats and ships electric switch.
Background technology
In the debug process of boats and ships, usually need to carry out overcurrent protection test to its electric switch, and traditional electric power meter is by voltage circuit, current return forms, and current return is wherein a circulation source, and it can not short circuit, can not disconnect.In long-term working practice, we find the fault handling of electric power meter current return, and the traditional Measures compare of the state confirmation before new equipment installation and operation bothers.Operating current return as found there is no electric current in the measurements, have two kinds may, one be short circuit, two is in open circuit, short-circuit loop, and directly having gone back without measurement meter in the path that electric current flows through, causes few metering, loses to national enterprise generation.General use step by step short circuit is measured with or without current lookup, but the mutual inductor of high-voltage meter is all placed in cabinet inside, There is nothing one can do, and need check under power down mode, if use multimeter measuring circuit, is all logical, can not find trouble spot.Also has a kind of open circuit conditions, its presentation is also do not have electric current, but this situation is dangerous, will there be high voltage at breakpoint place, jeopardize the safety of the person and equipment, consider based on this kind, needing to find a kind of better way, adding electric current when not powering on, can measure and need not power transmission for load, remove from and stop power transmission back and forth, safety is secure.
Utility model content
The utility model object is that the defect existed for prior art provides a kind of current signal generator for the debugging of boats and ships electric switch.
The utility model for achieving the above object, adopts following technical scheme: a kind of current signal generator for the debugging of boats and ships electric switch, comprises pressure regulation unit, voltage transformation unit, current detecting unit and multimeter; The output terminal of described pressure regulation unit is connected with voltage transformation unit, and the first output terminal of described voltage transformation unit is connected with the positive terminal of multimeter, and the second output terminal of described voltage transformation unit is connected with the negative pole end of multimeter by current detecting unit.
Further, described pressure regulation unit is made up of iron core, coil and housing; And on the input and output terminal of described pressure regulation unit, attemperating unit is housed, the control panel of described pressure regulation unit is equipped with warning device.
Further, described voltage transformation unit comprises transformer shell, internal coil, input lead and output lead; Described transformer shell is provided with air inlet and air outlet, described air outlet is provided with exhaust fan.
Further, described current detecting unit is reometer.
The beneficial effects of the utility model: current signal generator structure of the present utility model is simple, easy to use, can carry out overcurrent protection test to electric switch in boats and ships debugging fast; Can hidden danger be avoided, thus reach save time, laborsaving, the object of not losing electricity.

Embodiment
Shown in Fig. 1, relate to a kind of current signal generator for the debugging of boats and ships electric switch, comprise pressure regulation unit 10, voltage transformation unit 20, current detecting unit 30 and multimeter 40; The output terminal of described pressure regulation unit 10 is connected with voltage transformation unit 20, first output terminal of described voltage transformation unit 20 is connected with the positive terminal of multimeter 40, second output terminal of described voltage transformation unit 20 is connected with the negative pole end of multimeter 40 by current detecting unit 30, wherein, described current detecting unit 30 can adopt reometer.
During use, each electric switch in boats and ships is linked into the current signal input end that pressure regulation list shows 10, starting current signal generator, just can carries out overcurrent protection test to electric switch in boats and ships debugging fast by multimeter 40.
Shown in Fig. 2, pressure regulation unit 10 is made up of iron core 21 coil 22 and housing 27, and on the input and output terminal 24 of described pressure regulation unit, attemperating unit 25 is housed, and the control panel 23 of described pressure regulation unit is equipped with warning device 26.This pressure regulation unit 10 structure is simple, practical, cost is low, and which increase attemperating unit, it can avoid and reduce the improper various accidents caused of overload, overcurrent or working service because a variety of causes causes.
Shown in Fig. 3, this voltage transformation unit 20 comprises transformer shell 31 internal coil 32, input lead 36 and output lead 37; Described transformer shell 31 is provided with air inlet 33 and air outlet 34, described air outlet 34 is provided with exhaust fan 35, such transformer-energising, exhaust fan 35 just starts to rotate, wind is extracted out by exhaust fan 35 in transformer, by exhaust fan 35 exhausting, the air flowing in transformer can be increased, impel transformer coil to lower the temperature.Temperature is still lower after a long time use, can extension coil serviceable life, reduces disaster hidden-trouble.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc.All should be included within protection domain of the present utility model.
