Abstract

The invention discloses a fault location and alarm protection device for electromechanical equipment, which is used to solve the problems in the prior art that protection equipment such as thermal relays cannot guarantee the safe operation of the electromechanical equipment and cannot conveniently know the cause of the malfunction of the electromechanical equipment. The device includes: a starting module, used to start the motor or / and mechanical equipment, a fault location and alarm protection module, and a temperature monitoring module; Fault location, and control the start module to protect the motor or / and mechanical equipment from power failure; the temperature monitoring module is used to monitor the shell temperature of the motor or / and mechanical equipment, and when the shell temperature of the motor or / and mechanical equipment is higher than the set threshold Send a temperature alarm signal to the fault location and alarm protection module in real time. The above-mentioned device can remotely notify the maintenance personnel of the failure state, automatically stop the operation of the electromechanical equipment, and avoid overheating and burning of the electromechanical equipment.

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...
