Goldhome HMCXZW-450kW/200kV Partial Discharge-Free Variable Frequency Power Supply Control Cabinet Successfully Completes On-Site Testing
Recently, the Goldhome HMCXZW-450kW/200kV Partial Discharge-Free Variable Frequency Power Supply Control Cabinet was officially deployed at the customer's test site to conduct power-on commissioning, performance verification, partial discharge-free operating condition simulation, and integrated system testing. The equipment operated stably, with all technical indicators meeting specifications, marking a complete success for the on-site testing.
The HMCXZW-450kW/200kV Partial Discharge-Free Variable Frequency Power Supply Control Cabinet deployed on-site serves as the core control hub of the partial discharge-free high-voltage testing system, specifically designed for high-voltage, low-partial-discharge, and high-precision testing scenarios. Featuring high-power output, wide-frequency modulation, pure waveforms, and an extremely low partial discharge background, it can be precisely matched with partial discharge-free test transformers and series resonance systems. It is widely used for partial discharge detection and power frequency withstand voltage testing of high-voltage switches, transformers, GIS equipment, and power insulation products, meeting the high-standard testing requirements of research laboratories, high-voltage equipment manufacturers for type testing, and factory quality inspections.
Upon arrival and installation at the site, technical personnel strictly followed high-voltage testing standards and technical agreements to sequentially complete wiring verification, grounding checks, system parameter configuration, and closed-loop tuning of frequency and voltage. Through multi-stage voltage ramping, frequency sweeping, and extended steady-state load testing, the equipment's voltage regulation linearity, frequency stability accuracy, waveform distortion control, and partial discharge suppression capabilities were comprehensively evaluated.

The on-site test data demonstrated excellent performance: the equipment exhibited smooth voltage ramp-up, high voltage stabilization accuracy, and rapid frequency regulation response. Operation was free of abnormal corona interference, and the unit's partial discharge control performed exceptionally well. The output waveform was pure and distortion-free, and the multiple overvoltage, overcurrent, overheat, and flashover protection mechanisms operated with sensitivity and reliability, fully meeting the operating conditions required for the customer's high-standard partial discharge-free laboratory.
During the commissioning and testing phase, engineers provided the client's technical staff with simultaneous instruction on control cabinet operation procedures, parameter configuration methods, the principles of frequency conversion and regulation, testing safety protocols, and key points for daily maintenance. Through one-on-one hands-on training, they ensured the client's ability to independently conduct various high-voltage partial discharge and withstand voltage tests in the future.
The successful completion of the on-site testing for the HMCXZW-450kW/200kV partial discharge-free variable-frequency power supply control cabinet fully demonstrates Goldhome's R&D capabilities and manufacturing expertise in the field of partial discharge-free high-voltage testing equipment. Moving forward, the company will continue to focus on the high-precision partial discharge-free testing equipment sector, providing comprehensive high-voltage testing solutions to customers in the power industry through stable and reliable product quality and professional on-site technical services.
