Abstract

The invention discloses a motor overload short circuit protection device. The device comprises a shell; a first mounting plate and a second mounting plate are fixed to the inner wall of the shell fromleft to right; a fuse and a thermal relay are respectively mounted on the first mounting plate and the second mounting plate; a clamping groove is formed in the second mounting plate; the clamping groove is connected with a thermal relay in a clamping manner through a clamping block; the front end of the clamping block is in threaded connection with a fixing screw; the fixing screw penetrates through the clamping block to be in threaded connection with the second mounting plate; a temperature sensor and a temperature controller are sequentially mounted on the inner wall of the shell from topto bottom; a fan is mounted at the lower end of the shell; and the shell is in hinged connection with a box door through a hinge. By arranging the first mounting plate, the fuse, the second mounting plate, the thermal relay, the temperature sensor, the fan, the temperature controller and the fixing screw, the problems that the protection effect is poor, mounting and dismounting are not easy, no automatic heat dissipation function exists, the function is single, and the practicability is not high are solved.

Description

technical field [0001] The invention relates to the technical field of overload and short circuit protection devices, in particular to an overload and short circuit protection device for motors. Background technique [0002] Motors, referred to as motors, are the heart of industrial control and the basis of power. On the one hand, the growth of the overall demand for motors comes from the synchronous growth brought about by the growth of power installed capacity, power and other energy consumption. At the same time, there will be demand for motors driven by automation demand. And the replacement demand brought by high-efficiency motor applications. When installing the motor, it is necessary to install an overload and short circuit protection device to avoid damage to the motor due to overload and short circuit, resulting in economic losses. [0003] But the existing technology also has the following deficiencies: [0004] 1. The existing motor overload and short circuit pr...
