Product Introduction

The SXBP Series Variable Frequency Series Resonant Test Equipment is designed to meet the insulation testing requirements of high-voltage electrical equipment in power transmission, distribution and electrical manufacturing applications.
Based on variable-frequency series resonance technology, the system integrates a frequency conversion power supply, excitation transformer, resonant reactors and a control and measurement unit. By adjusting the operating frequency to match the characteristics of the test circuit, the system generates the required AC test voltage under suitable resonant conditions.

Key Product Advantages

-Variable-Frequency Resonance TechnologyThe adjustable-frequency power supply enables the system to establish resonance with the test circuit within its specified operating range. This supports AC withstand voltage testing of suitable capacitive electrical equipment.

-Modular System ArchitectureThe system consists of separate functional components, including the variable frequency power supply, excitation transformer and resonant reactors. Their ratings and arrangement can be selected according to the required test conditions.

-Flexible Application ConfigurationDifferent test objects require different voltage, capacitance and duration parameters. The SXBP Series can be evaluated for various applications, subject to the capabilities of the selected configuration.

-Digital Control and MeasurementThe control and measurement unit supports convenient system operation and monitoring of relevant test parameters. Available control, measurement and protection functions depend on the supplied configuration.

-Suitable for Field and Laboratory ApplicationsThe modular arrangement can support on-site testing and laboratory use where transportation, installation, power supply and safety requirements are properly addressed.

Typical Applications

•Power Cable Testing: AC withstand voltage testing of applicable medium- and high-voltage power cables.

•GIS Testing: Insulation withstand voltage testing of compatible gas-insulated switchgear assemblies.

•Transformer Testing: Applicable AC insulation tests for transformers and related electrical equipment.

•Switchgear Testing: Testing of circuit breakers, disconnectors and other suitable high-voltage apparatus.

•Electrical Testing Laboratories: High-voltage insulation testing in equipment manufacturing, inspection and commissioning environments.

FAQ

Q1. What factors should be considered when selecting a resonant test system?
The main selection factors include the required AC test voltage, test-object capacitance, operating frequency, test duration and site power supply. The equipment configuration should be evaluated based on the complete testing requirements rather than the voltage rating alone.

Q2. Why is variable-frequency technology used in series resonant testing?
Variable-frequency technology allows the operating frequency to be adjusted to establish resonance between the inductive reactance of the resonant reactor and the capacitive reactance of the test object. This enables the system to accommodate different capacitive loads within its specified operating range.

Q3. How does test-object capacitance affect system selection?
Test-object capacitance directly affects the resonant frequency and the required reactor configuration. For cable testing, capacitance is influenced by the cable design and length. Providing the capacitance value or cable parameters helps the manufacturer evaluate a suitable system configuration.

Q4. Can the SXBP Series be used for long-distance power cable testing?
The system may be configured for power cables with different lengths, subject to the required test voltage, cable capacitance, operating frequency, rated capacity and test duration. Please provide the cable specifications and test requirements for technical evaluation.
