Power supply problems related to poor construction and installation of power supply bureau and throughout the building, we are very thorough difficult decisions in the installation work, the company after years of summary and case studies, research and development of insulated hanger , it can effectively avoid the bad power generated burning question projector interface. Has adopted the insulation hanger mounted projectors to produce over currently do not have a problem .
3 , ceiling machines generally with the signal source and power distance, so it was a non-standard installation: the projector directly from the roof lighting power , this approach is very safe . Because a lot of times to three-phase power grid load balancing , wall sockets and lighting were taken from the roof of a two-phase power supply different , there is a voltage between the two -phase 380V power supply , there will be zero line between the ground and a large potential difference this appears to be the installation image disturbance ranging from heavy machine interface part will be burned .
Therefore, we emphasize the first one from the same power supply, this principle is equally important here .
4, the power of the projector and related equipment to avoid high-power air conditioners, and other devices sharing the same Dayong power supply , air conditioning and other equipment to start because there is a very high peak voltage pulse generation in the grid , these pulses First would interfere with the signal , the second is the power generated will be damaged.
Anhui Province, a place when installing a projector in the stock market and share a cabinet air outlet , part of a continuous supply aircraft burned, Beijing continuous maintenance staff repeatedly fail to locate the cause of damage to the site visit later in the user found the problem lies.
