Electromagnetic Shielded Chamber for Testing

Product Description

   Electromagnetic Shielded Chamber For Testing

 

Product Description

 

A partial discharge shielding room (PDSR) is a specialized environment designed to test and measure partial discharges in electrical equipment. Partial discharges are localized dielectric breakdowns that occur in high voltage insulation systems and can be indicative of insulation defects. Proper testing and measurement of partial discharges are crucial for ensuring the reliability and longevity of high voltage electrical equipment, such as transformers, cables, and switchgear.

Specification

Shielding Performance:	0.15~1.6MHz ≥60dB
Background Noise	≤2Pc (when the test object is not energized)
Reverberation Time	t ≤5s (at 400Hz)
Application	Suitable for partial discharge tests or impulse tests for cables, transformers, instrument transformers, switches, and substations with voltage levels of 35KV and below.

 

Feature

 

1. Shielding Body:

   • Made of high-quality galvanized steel sheets (punched with micro-holes), processed into modular frames, and fixed with conductive liners using bolts to form a six-sided shell. It ensures reliable electromagnetic sealing and facilitates convenient assembly and disassembly.

2. Shielding Door:

   • The main shielding door (for the entry and exit of test objects) adopts an airtight sliding structure. The door operates with variable frequency speed regulation and PLC program control, featuring touch screen operation, smooth and noise-free opening, anti-pinch safety functions, and customizable exterior decoration according to customer requirements.
   • The smaller shielding door (for personnel entry and exit) can be customized for manual or electric operation as per customer needs.

3. Shielding Accessories:

   • Ventilation waveguide windows, filters, and dedicated waveguide tubes for shielding.

4. Control Room:

   • Constructed with a steel frame or steel plate assembly structure. To meet the test requirements of the test objects and ensure personnel safety, a shielding observation window is installed facing the test area for monitoring the operation of the test objects. Interior decoration can be customized according to customer requirements.

Application

 

 

1. Testing Electrical Equipment:

   • Cables: Ensuring the integrity of insulation in power and communication cables by detecting partial discharges that indicate weak points or defects.
   • Transformers: Testing power and distribution transformers to detect insulation degradation or manufacturing defects.
   • Instrument Transformers (Current and Voltage Transformers): Assessing the insulation quality and detecting potential partial discharges in instrument transformers used in high-voltage applications.
   • Switchgear: Evaluating the insulation condition in switchgear to prevent failures and ensure reliable operation.
   • Motors and Generators: Checking for partial discharges in the stator windings of large motors and generators, which can indicate insulation weaknesses.

2. Quality Control in Manufacturing:

   • New Product Testing: Manufacturers of high-voltage equipment use PDSRs to conduct routine tests on new products before they leave the factory, ensuring they meet required standards and specifications.
   • Prototype Testing: During the development of new designs, prototypes are tested for partial discharge to validate their insulation performance and make necessary improvements.

3. Maintenance and Diagnostics:

   • Condition Monitoring: Regular testing of in-service equipment to monitor the condition of insulation and identify any emerging issues before they lead to failures.
   • Predictive Maintenance: Using PD measurements as part of a predictive maintenance program to schedule repairs or replacements before catastrophic failures occur, thereby reducing downtime and maintenance costs.

4. Research and Development:

   • Material Testing: Investigating the performance of new insulating materials under high-voltage conditions to develop better, more reliable products.
   • Design Optimization: Testing different design configurations to optimize the performance and reliability of high-voltage equipment.

5. Compliance and Certification:

   • Standards Compliance: Ensuring that electrical equipment complies with international and industry standards for partial discharge, such as IEC 60270.
   • Certification: Gaining certification for high-voltage equipment by demonstrating compliance with regulatory and industry standards through rigorous PD testing.

This equiment is suitable for partial discharge test or impulse test of cables, transformers, transformer switches and power stations with voltage level 35KV and below.
