Description

The utility model relates to electrical engineering and can be used to determine short-circuited turns in the inductors of various electrical devices (transformers, electric motors, etc.).
The well-known "METHOD FOR CONTROL OF THE AVAILABILITY OF SHORT-CLOSED CIRCUITS IN THE INDUCTION COIL" RU (11) 2148265 [1], containing a direct current source, a key, an integrator, a registrar and a resistor.
A disadvantage of the known design is the need for an unjustified increase in the power of the DC source.
Closest to the claimed technical solution is "METHOD FOR CONTROL OF VOLTAGE INSULATION OF WINDING OF ELECTRIC MACHINES AND APPLIANCES AND DEVICE FOR ITS IMPLEMENTATION", RU 2035744 [2], containing a storage capacitor charging source, a storage capacitor, a power switch, a power connection terminal, a power control terminal, a power control device control, voltage divider, voltage meter.
The known design [2] allows to reduce the power of the DC source due to the presence of the storage capacitor.
A disadvantage of the known design is the narrow scope associated with the difficulty of tuning the voltage of the test pulse, the lack of automation of test work. In addition, the known design has a low sensitivity to winding defects, which at the time of verification has a relatively small effect on the characteristics, but potentially dangerous with the further use of the controlled product.
The technical result of the proposed utility model is the expansion of the scope, gaining the ability to automate testing, increasing sensitivity.
The technical result is achieved by the fact that the coil short circuit finder, comprising a power source, a storage capacitor, a power switch, a power switch control device, control object connection terminals, a voltage divider, a voltage meter, is characterized in that it further comprises a controllable power source further comprising a power control controller circuits, the outputs of which are connected to the control input of a controlled power source and to the input of the power switch control device
The different circuit finder may further comprise a current-measuring resistor connected in series with the storage capacitor. The presence of a current-measuring resistor will allow you to control the current passing in the discharge circuit of the storage capacitor, which will allow you to get more data about the measurement object and improve the accuracy of its qualification.
The coil closure finder may further comprise a control unit for measuring and information circuits to which a keyboard unit, an LED indicator unit and a liquid crystal display unit are connected, a voltage divider output, a “START” signal terminal, and a communication line with a power circuit control controller. The control circuit for measuring and information circuits will make it easy to configure the device due to the presence of a keyboard, reading information due to the connection to the divider unit, the presence of indicator blocks, and also to facilitate the process of controlling the power part of the device through a communication line with the power circuit control controller and the “START” signal.
The coil closure finder may further comprise a storage capacitor pump generator coupled to the high voltage unit, which in turn is connected to the storage capacitor. The presence of a pump generator will increase the efficiency of the device and form the required amount of charge of the storage capacitor.
The role of the power key can perform a thyristor. The thyristor has the necessary pulse rise rate and the ability to automatically turn off when the value of the power current passes through zero, which can be used in measurement schemes.

Energy from a controlled power supply is supplied to a pump generator 3, from which energy is supplied to a high-voltage unit 4 and to a storage capacitor 5. From the storage capacitor, the top according to the lining scheme, 5, the energy through the power switch 6 and the current-measuring resistor 7 through the control object (not shown) is supplied to the connection terminals of the control object 9 to the lower according to the circuit the accumulator capacitor 5. The connection terminals of the test object 9 are connected to the input of the divider unit 10. The control outputs of the power circuit control controller 11 are connected to the control inputs of the controlled power supply 2 and the control input of the key control device 8. The power circuit control controller 11 and the control controller information circuits 12 are connected by a communication line. The keyboard controller 13, the LED indicator block 14, the block are connected to the controller for controlling the measurement and information circuits 12
a liquid crystal indicator 15 and a signal terminal “START” 16. Depending on the selected measurement program entered through the keyboard block 13, the controller for measuring and information circuits 12 controls the charging and discharging of the storage capacitor 5 by means of commands transmitted via the communication line to the controller 11 control circuits connected to the controller control the power circuits 11, digitizes the data received from the block of dividers 10 and displays the result on the block of the LED indicator 14 and the block of the liquid crystal indicator 15. When embedding the finder of short circuits in an external monitoring system, control can be performed by an external signal supplied to the “START” terminal 15.
The technical result - the expansion of the scope, due to the fact that it is possible to use the same device to control a wide range of different winding products, as there is the possibility of software tuning the voltage of the storage capacitor and software changing the processing of the result. This technical result ensures the presence in the inventive device of the controller controlling the power circuits and the associated controlled power source.
