Abstract

The invention discloses a dynamo-electric equipment fault positioning and alarm protective device, which aims to solve the problems that in the prior art, an electrothermal relay or other protective devices cannot guarantee the safe running of the dynamo-electric equipment and the fault reason of the dynamo-electric equipment cannot be conveniently known. The device includes a starting module for starting a motor or / and a mechanical device, a fault positioning and alarm protective module, and a temperature monitoring module; the fault positioning and alarm protective module for performing fault positioning after the temperature alarm signal transmitted by the temperature monitoring module is received, and controlling the starting module to protect the motor or / and the mechanical device in a power-off manner; and the temperature monitoring module for monitoring the housing temperature of the motor or / and the mechanical device, and transmitting the temperature alarm signals to the fault positioning and alarm protective module when the housing temperature of the motor or / and the mechanical device is higher than the set threshold. The device can remotely inform maintenance personnel the fault state, automatically stops the running of the dynamo-electric equipment, and prevents the dynamo-electric equipment from overheating and burning out.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a fault location and alarm protection device for electromechanical equipment. Background technique [0002] The motor is a device that converts electrical energy into mechanical energy. The main factor that has the greatest impact on the life of the motor is temperature. Excessive temperature greatly affects the life of the motor. In the prior art, it is impossible to reliably protect the safety of the motor during production and operation. Due to factors such as overload and overcurrent, open-phase operation and overcurrent, bearing wear, and external air ducts, the motor overheats the fuselage shell, causing the motor winding coil to burn and other components to be damaged, which brings time and manpower to the production economy. and a great waste of materials. [0003] Today's motor protection technical measures are completed by thermal relays and motor comprehensive protectors t...
