Purpose & brief description |
● Shielding test room is mainly used to prevent the interference of electromagnetic wave from space to partial discharge test and ensure the accuracy of partial discharge test data. ● Application: power product manufacturing companies, power operation departments, scientific research institutions and colleges and universities. ● Application products: all kinds of insulating parts, medium voltage switchgear, GIS high-voltage switch, cable and cable accessories, transformer, power transformer, high-voltage circuit breaker, capacitor bushing, motor, lightning arrester, photovoltaic products and other high-voltage electrical components and insulating materials. |
Test purpose |
● The shielding room is mainly used to isolate from external electromagnetic interference and ensure the normal operation of indoor electronic and electrical equipment. Especially in the measurement and testing of electronic components and electrical equipment, the electromagnetic shielding room (or darkroom) is used to simulate the ideal electromagnetic environment and improve the accuracy of the test results. ● Shielding room is mainly used for partial discharge test to ensure the accuracy of partial discharge test. ● As one of the main interference sources in the partial discharge test of space electromagnetic interference, the shielding room is the best way to eliminate the space electromagnetic interference in the partial discharge test. ● Causes of space electromagnetic interference: such as adjacent high-voltage live equipment or high-voltage transmission and distribution lines, static or magnetic induction and electromagnetic radiation such as radio communication, and high-frequency signals such as thyristor. ● Space electromagnetic interference is generally directly coupled through space. When the partial discharge test circuit is not closed, the space interference is great, resulting in the inability to carry out the partial discharge test. |
Technical parameter |
● Shielding room performance: shielding attenuation effect The shielding room can achieve the following shielding effects in the range of high frequency 10kHz to tens of MHz: Magnetic field: > 60dB at frequency 10kHz... 100 kHz Electric field: > 60dB at frequency 1kHz... 1GHz ● Insulation index of insulation isolation layer: > 1000m Ω ● Grounding resistance ≤ 1 Ω ● Overall system spatial background noise level ≤ 1p |
Technical features |
● The new process does not require concrete pouring, which saves the buyer concrete and related construction costs. Moreover, the flatness inside and outside the shielding room can be almost the same without excavation (the difference between the internal and external floors is 2cm) ● The control room is separated from the test area and equipped with a high-definition observation window to facilitate the observation of test conditions during the test. ● The shielded gate can be customized into electric mobile type according to requirements, which is convenient for opening and closing and beautiful ● Shielded electric sliding door: high shielding performance ● It can cooperate with the roller line, with a high degree of automation and improved work efficiency |
