Abstract

A push rod, Motor protector and push rod processing method are provided, The pushing rod comprises a first pushing rod (10), a second pushing rod (20) and a plurality of pushing members (30) connecting the first pushing rod (10) and the second pushing rod (20), each pushing member (30) having a mounting space (31) cooperating with a corresponding metal sheet (51) in a determined position after mounting by the plurality of metal sheets (51). The technical proposal of the invention effectively solves the problem that the mounting error of the bimetal sheet in the prior art causes the distance between each bimetal sheet and the pushrod to be different and affects the tripping time.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a push rod, a motor protector and a processing method for the push rod. Background technique [0002] At present, motor protectors are mainly used for overload, phase loss, undervoltage and short circuit protection of three-phase motors. When the above abnormalities occur in the circuit, in order to protect the motor from damage, the motor protector must cut off the power supply in time to protect the motor according to the characteristics of the motor and product standards. At the same time, it must be considered that the change of the ambient temperature will affect the overload trip. characteristic. [0003] In the prior art, motor protectors mainly include electronic and thermal-magnetic motor protectors. For the reliability of protection safety, thermal magnetic motor protector is the first choice. like figure 1 As shown, the motor protector includes a middl...
