Abstract

The embodiment of the invention provides a generator protection device and method. The generator protection device comprises a collection module which is used for collecting the rotating speed of a generator and the voltage of the generator; a control module which is electrically connected with the acquisition module and is used for receiving the rotating speed and the voltage sent by the acquisition module, and if the rotating speed and the voltage meet the preset conditions, generating an execution instruction; and an execution module which is electrically connected with the control module and an outlet switch of the generator, and is used for receiving the execution instruction sent by the control module and executing an operation of switching off the outlet switch according to the execution instruction, so that the generator can be prevented from becoming a motor, and the burning loss of the generator is prevented.

Description

technical field [0001] Embodiments of the present invention relate to a generator protection device and method. Background technique [0002] Industrial development is inseparable from the development of motors. When the generator is out of service, if the generator is misoperated, the grid will send power to the generator, making the generator a motor and causing the generator to burn out. Contents of the invention [0003] The problem to be solved by the invention [0004] The purpose of the embodiments of the present invention is to provide a generator protection device and method, which can prevent the generator from turning into a motor, so as to prevent the generator from burning out. [0005] solutions to problems [0006] In order to achieve the above purpose, in the first aspect of the embodiment of the present invention, a generator protection device is proposed, which includes: [0007] An acquisition module, configured to acquire the rotational speed of t...
