HZSP Transformer Induced Over Voltage Withstand Test Equipment

I. Basic Principles

According to national standard "GB311-64" and the original water and electricity department issued "regulations of the preventive test electrical equipment, to meet the power system of high voltage transformer, frequency doubling induced overvoltage withstand test equipment requirements and design, it is widely used in power system, 35-220 kv voltage transformer ac withstand voltage test of grade, with main longitudinal assessment of transformer insulation strength, at the same time can also be induced overvoltage withstand test was carried out on the motor and transformer winding, also to make a short run of 150 hz power supply.

II. Product Organization

It is composed of three-phase five-column transformer (or three single-phase transformers), single-phase voltage regulator, reactor and control part.According to the user requirements, the shape can be integral type, can also be split type.

III.Main Function

1. It is widely used in voltage transformers for frequency doubling induction voltage withstand test.

2. Conduct the voltage withstand test of the power transformer with split-phase frequency induction.

3. Perform frequency doubling induction voltage test on other induction coil type electrical products.

IV.Technical Parameters

1.Input voltage: three-phase 380V 50HZ

2.Output voltage: single-phase 300V, 500V, 800V, 1000V single-phase 150HZ

(external booster transformer is required if higher voltage is required)

3.Output capacity: 20% of product capacity

4.Harmonic distortion: < 5%-8%

5.No load running time: less than 5 minutes

6.Duration under rated voltage: 40 seconds
