Abstract

The invention discloses a protector core for a motor. The protector core comprises a control device, a detection device, a signal conditioning device, a phase sequence detection device, a short-range serial port device, a remote DeviceNet communication device, a display panel device, an output relay device and a switching power device, wherein the signal conditioning device, the phase sequence detection device, the short-range serial port device, the remote DeviceNet communication device, the display panel device and the output relay device are connected with the control device; the signal conditioning device and the phase sequence detection device are connected with the detection device; and the switching power device provides direct current power for a protector. A working current signal of the motor is converted through the detection device, the signal conditioning device and the phase sequence detection device, the control device controls the output relay device and the display panel device according to various protection algorithms for a thermal overload, a phase sequence and the like to fulfill the aims of protection and field display, and working parameters of the protector are configured and monitored remotely and within a short range to fulfill the aims of intelligent failure control and diagnosis.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a motor protector core and a motor protection method. Background technique [0002] The use of motors has penetrated into almost every industry. It is very important to ensure their normal operation. However, in actual use, it is not uncommon to cause motors to burn out or even cause major safety accidents. Good protection of motors is of great importance to improve production efficiency and economic benefits and ensure safe production. Significance. Existing motor protectors have disadvantages such as low intelligence and few protection functions. They do not have remote communication functions and cannot meet the requirements of comprehensive protection of motors, real-time modification of protection parameters, and development of networked control systems. Contents of the invention [0003] In view of the lack of protection functions of existing motor protec...
