Motor frequency withstand voltage tester

(Motor) power frequency withstand voltage testerOverview and Characteristics:

The power frequency withstand voltage test is an important test item for the production and use departments of motors (transformers) to inspect the insulation performance of motor components (semi-finished products) and finished motor products. The quality of this performance will directly affect the reliability of the motor and personal safety. Therefore, the power frequency withstand voltage tester is an important testing equipment for motor production, research, operation, maintenance, and inspection departments. This instrument is also a safety performance testing equipment for electrical equipment.

PVT-35The power frequency withstand voltage tester is a voltage withstand testing equipment specifically designed for the motor (transformer) industry. Product complianceGB1032-2012Test Methods for Three phase Asynchronous MotorsGB1311-2005Test Methods for DC MotorsGB1029-2005Test Methods for Three phase Synchronous MotorsGB14711-2013The power frequency withstand voltage test requirements proposed in the General Safety Requirements for Small and Medium sized Rotating Electrical Machines.

Feature 1: This product uses an electric voltage regulator to adjust the primary input voltage of the high-voltage test transformer to regulate the overall high-voltage output of the machine. After the boost is started, it rises to the rated test value at a certain rate, and then uses a digital meter to display the time and control the test time; At the end of the experiment, the electric voltage regulator still reduces the voltage to zero at the same rate; In the experiment, if the leakage current of the product exceeds the set value, the instrument will automatically alarm and cut off the high voltage. The electric voltage regulator will automatically reduce the voltage to zero, and at the same time, the electric bell will alarm and the alarm indicator light will be on. This machine is equipped with a discharge button, which can release the residual voltage of the tested product and protect the personal safety of the operator; In addition, the instrument is equipped with a warning light for high voltage warning and a mushroom shaped "emergency stop" button.

Feature 2:PVT-50The type of power frequency withstand voltage tester has the function of finding the fault point of the motor: if the tested product alarms and is judged as unqualified during the experiment, the "hand/Place the "Auto" button in the "Manual" position, then set the leakage current to the maximum allowable value of the instrument, and slowly increase the test voltage through the "Boost" button until the ignition point is seen.
