Problems solved by technology

When the mains power is not normal, start the oil generator to supply power. Temporary start of the oil generator takes a long time, which will cause power interruption for several minutes
For high-power electrical equipment that requires continuous power supply, such as air traffic control radar equipment, airport runway lights, etc., once the power supply is interrupted, it will lead to interruption of monitoring, pilots cannot see the runway, etc., the consequences are more serious
[0003] In order to prevent the loss of key data, UPS is often equipped, but due to the large load power, UPS needs to store more power to achieve the goal, and its cost is relatively high

Abstract

The invention discloses a double-oil-engine and commercial power seamless switching system, and relates to the field of electric power. The system comprises commercial power, a first oil engine, a second oil engine and a monitoring system, wherein the commercial power is connected with a first change-over switch through a first electrical parameter detector, the first oil engine is connected witha second change-over switch through a second electrical parameter detector, the second oil engine is connected with a third change-over switch through a third electrical parameter detector, and the first electrical parameter detector, the second electrical parameter detector and the third electrical parameter detector are connected with the monitoring system. According to the invention, when commercial power is abnormal, the switching system can complete switching of a load power supply within several milliseconds, so that the purpose that the load equipment is not shut down all the time is achieved. The invention further relates to a using method of the double-oil-engine and commercial power seamless switching system.

Description

technical field [0001] The invention relates to the field of electric power, more specifically it is a system for seamless switching between dual oil generators and mains power supply. The present invention also relates to a method for using the seamless switching system between dual oil generators and mains power supply. Background technique [0002] In the case of mains power supply, an oil generator is often used as a backup power supply. When the mains power is not normal, the oil generator is started to supply power. It takes a long time to start the oil generator temporarily, which will cause a power interruption of several minutes. For high-power electrical equipment that requires continuous power supply, such as air traffic control radar equipment, airport runway lights, etc., once the power supply is interrupted, it will lead to interruption of monitoring and pilots being unable to see the runway clearly, with serious consequences. [0003] In order to prevent the...
