The principle that both ends generate voltage is made, and shunting is selected by the mV numbers labelled on ammeter used or volt-ammeter dial plate
Generally the most commonly used is 75mV or 45mV for the rated voltage drop specification of device, if ammeter used uses the electricity of following formula computational chart without this value
Pressure amount limits, the then rated voltage drop specification of reselection current divider, by selected two current terminals of current divider respectively with power supply and bear
Load is connected, and current potential terminates ammeter, it should be noted that the terminal DJ623-8 polarity of ammeter will connect pair, then the amount of ammeter
Journey has just been expanded to the current value demarcated on current divider, motor test is measured, often one piece of ammeter will configure multiple points
Device is flowed, to solve the problems, such as to require all shuntings used at this time in the accuracy of measurement that can ensure requirement compared with wide-measuring range
The rated voltage drop of device is all consistent with matched ammeter, such as 75mV, in this way, after current divider is selected, the full scale of ammeter is just
It is the load current value of selected current divider, the every lattice electric current number of multiple i.e. its dial scale of ammeter is the specified electricity of current divider
Stream is except in the total lattice number of dial scale；The current transducer 3072 can be directly by tested major loop alternating current or direct current
Electric current is converted into the DC4~20mA exported by linear scale and converts 1~5V of DC by 250 Ω resistance or turned by 500 Ω resistance
DC2~10V constant current ring standard signals are changed, reception device computer or display instrument are delivered continuously to.
Its structure and principle, which are all this technology personnel, can be learnt by technical manual or be known by routine experiment method,
Problems solved by the invention is that the prior art is usually embedded with temperature detecting resistance in the iron core of stator, passes through these temperature detecting resistances and prison
Equipment connection is controlled, stator temperature can be real-time monitored, but since the rotor of water conservancy generator is rotary part, if in rotor
Everywhere in be embedded to temperature detecting resistance, then need to fill many brushes and draw signal, this will necessarily bring to the safe operation of generator
Hidden danger, and be difficult to realize in technique, the present invention is combined with each other by above-mentioned component, and turning for generator is measured using indirect method
Sub- temperature, by equipped with current divider, current transducer, voltage transmitter the temperature of generator amature is measured, in turn
The temperature measurement is transferred to processor by the electric current of measurement with voltage value by temperature controller to be analyzed and calculated, therefore
The temperature control for realizing generator, avoids being embedded to temperature detecting resistance everywhere in rotor, effectively avoids the safety fortune of the generator
Row hidden danger, and it is easy to operate, highly practical, temperature controller can also carry out telecommunication, what realization controlled generator-temperature detection
Monitoring in real time, effectively improves its service life, described in detail below：
