Integrated motor protector

Abstract

The invention discloses an integrated motor protector comprising a base, a housing, a temperature measuring module, a voltage measuring module, a current measuring module, a phase loss protection module, an address encoding module, a drive module, an I / O (input / output) module, an alarm module, a display, a keyboard, a transmission module and a data processing module. The drive module is electrically connected with the temperature measuring module, the voltage measuring module, the current measuring module, the phase loss protection module, the address encoding module, the I / O module and the data processing module. The I / O module is electrically connected with the alarm module, the display, the keyboard and the transmission module. The integrated motor protector is capable of monitoring and displaying parameters, such as current, voltage and temperature rise, during the whole operating process of a motor and sending out a warning in case of abnormalities; the integrated motor protector also supports the functions of address encoding supporting and monitoring data transmission, remote central monitoring of multiple motors is greatly facilitated, thereby lowering motor operation cost is lowered and improving work efficiency.

Description

technical field [0001] The invention relates to a motor comprehensive protection device, which belongs to the field of motor protection equipment. Background technique [0002] The electric motor is currently the most important and widely used electrical equipment that converts electrical energy into mechanical energy. Due to the unreasonable use of the electric motor or the failure of the equipment, it is very easy to cause the load driven by it to exceed its rated power, causing internal damage to the electric motor. The coil current increases, which leads to a very high temperature of the coil, which seriously affects the service life of the motor coil insulation. In serious cases, it directly causes the motor coil to be burned, causing serious damage to the motor. At the same time, due to the failure of the external power supply line, the power supply phase loss often occurs or sudden power failure, especially when the power supply is out of phase, it is very easy to cau...

[0002] The electric motor is currently the most important and widely used electrical equipment that converts electrical energy into mechanical energy. Due to the unreasonable use of the electric motor or the failure of the equipment, it is very easy to cause the load driven by it to exceed its rated power, causing internal damage to the electric motor. The coil current increases, which leads to a very high temperature of the coil, which seriously affects the service life of the motor coil insulation. In serious cases, it directly causes the motor coil to be burned, causing serious damage to the motor. At the same time, due to the failure of the external power supply line, the power supply phase loss often occurs or sudden power failure, especially when the power supply is out of phase, it is very easy to cause the motor coil to burn out. At present, the monitoring and management of the motor mainly relies on the maintenance personnel to conduct regular inspections on the motor, but this inspection can only be performed by the main motor. The temperature is directly detected, and the load current of the motor cannot be directly detected, so it is very easy to cause missed inspections. At the same time, due to the regular inspection of the motor, it is impossible to monitor the motor throughout the whole process, especially for some large motors or large-scale distribution areas. For a wide range of motors, relying on manual regular inspections is far from meeting the needs of ensuring the safe operation of the motor. Therefore, there is an urgent need for a monitoring and protection device that can monitor the working status of the motor and can support remote centralized monitoring.
