Induction voltage withstand test deviceProduct Introduction

Tuopu brandManufacturer of induction voltage withstand test deviceproductIt is a lightweight voltage transformer induction withstand voltage test equipment made by utilizing the saturation characteristics of the magnetization curve of silicon steel sheet iron core in the power grid, and inducing zero sequence third harmonic potential in the secondary coil of the transformer connected in an open triangle.
The TPSBF series triple frequency generator is one of the basic equipment for conducting double frequency induction high voltage tests on small capacity power transformers and series high voltage transformers in power systems, power plants, substations, and power distribution networks. It can also be used for frequency doubling and voltage doubling tests on various low-voltage electronic and instrument power transformers, inductance coils, and electrical coils. It can also be used as a frequency doubling power supply with a power not exceeding 1 kW for the power supply or testing of certain special electrical equipment.
This product is a static frequency conversion device with low noise and small size, which can replace traditional frequency conversion units in high-voltage systems.

Manufacturer of induction voltage withstand test deviceProduct Principle
Three single-phase transformers are connected in a star shape on the primary side and an open triangle shape on the secondary side. When a symmetrical three-phase sine wave power supply is added to the primary side and the voltage is increased to saturate the magnetic circuit of the iron core, the third harmonic component of the magnetic flux in the iron core increases, and the induced third harmonic voltage on the iron core coil also increases accordingly. The 150 Hz (three times the power frequency) induced voltage output from the secondary side of the open triangle generator is used as the triple frequency test power supply voltage.
When the third harmonic generator is loaded with a load (such as JCC-220 high-voltage series voltage transformer), its current changes from inductive to capacitive. Due to the low power factor, the efficiency of the generator is relatively low, usually only about 20%. Therefore, a reactor can be connected to a certain empty winding of the test sample for current compensation. To improve the power factor of the entire test circuit.
