Technical Field

The utility model belongs to the technical field of asynchronous generators, in particular to an automatic input device for asynchronous generators.

Background Art

The automatic start-up device of asynchronous generator is an automatic control system, which can be automatically put into use when the power grid fails or the power is lost to ensure the stability and continuity of the power system. The working principle of this device is to use the characteristics of the motor to detect and judge before the motor starts to ensure the correct start-up of the motor.

Generally speaking, the automatic start-up device of an asynchronous generator includes the following parts, which are usually divided into a detection module, a control module and a protection module. It is mainly used for protection before the motor starts, such as cutting off the power supply, sounding an alarm, etc.

In the current existing technology, when an asynchronous engine is in use, when a power outage occurs in the power grid, it is necessary to put it into use through an asynchronous generator. However, the existing method of putting it into use usually requires manual alignment with the power supply of the power grid for power supply. Since the port installation is in an exposed state, electric shock problems are likely to occur when workers are installing it.
