Partial discharge laboratory is used to isolate and interfere with external currents. Under the action of an electric field, the insulation system suspends partial discharge in certain areas without breakdown. This phenomenon is called partial discharge, and the existence of partial discharge laboratory is to isolate it. Next, let's follow the editor to see what the principle of isolation is?
Partial discharge shielding room can isolate 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, using electromagnetic shielding rooms (or darkrooms) to simulate ideal electromagnetic environments can improve the accuracy of detection results.
Block the diffusion of electromagnetic radiation from the partial discharge shielding room to the outside world. Prevent information leakage from electronic communication devices and ensure information security. The military command communication elements must have the ability to resist enemy electromagnetic interference, and in the event of electromagnetic interference attacks or even nuclear explosions, combined with other protective elements, protect electronic communication equipment from damage and normal operation.
1. Electromagnetic shielding door: Electromagnetic shielding is the main moving component of the electromagnetic shielding room and the key to the comprehensive shielding effectiveness of the shielding room. It has high technical content, special materials, and complex processes, with a total of 426 procedures. Electromagnetic shielding doors are divided into two categories: hinged blade doors and sliding doors, each with manual, electric, fully automatic, and other forms. If considering the stability and cost-effectiveness of use, manual knife type hinged doors;
2. Honeycomb ventilation system: Ventilation and air conditioning are essential facilities for shielded rooms. The honeycomb waveguide window is composed of a collection of hexagonal steel waveguide tubes with a distance of 42mm from each other. The waveguide tubes do not obstruct air flow, but have a cutoff effect on electromagnetic radiation. At present, fully welded honeycomb waveguide windows with specifications of 300mm x 300mm x 42mm are mainly used, with insertion loss of 150KHz~1GHz ≥ 100dB, fully meeting the regulatory requirements. In order to ensure that the partial discharge shielding room can effectively isolate external interference, corresponding protective measures should be taken to protect electronic communication equipment from damage and interference.
How to isolate the interference of relative electromagnetic waves on machinery, how to ensure electronic information security, etc. The above is the principle of partial discharge shielding room that the editor will explain to you! Hope it's helpful to everyone!
