Abstract

The invention relates to a temperature measuring junction box device which comprises an upper junction box cover, winding temperature measuring control wires, connecting terminals, an incoming line locking threaded sleeve, a junction box seat, a lower junction box cover, and an outgoing line locking threaded sleeve, wherein the upper junction box cover and the lower junction box cover are fastened at the upper and lower ends of the junction box seat respectively; a bearing temperature measuring probe is fixed on the upper junction box cover; the outgoing line locking threaded sleeve is mounted on the junction box seat; the connecting terminals are mounted in the junction box seat; the winding temperature measuring control wires are connected with the connecting terminals; the incoming line locking threaded sleeve is mounted at the bottom of the junction box seat; the winding temperature measuring control wires are connected into the connecting terminals through the incoming line locking threaded sleeve. The temperature measuring junction box device has the advantages that the structure is simple and reasonable; a temperature measuring entrance hole is formed in the bottom of a junction box instead of the top of the junction box seat without changing any part of the temperature measuring junction box, so as to improve the protection grade of the temperature measuring junction box, overcome unsafe factors caused by water inflow and other problems of the temperature measuring junction box, and further protect a motor.

Description

technical field [0001] The invention relates to a temperature-measuring junction box device, in particular to monitor and protect a motor; it is used to improve the protection level of the temperature-measuring junction box. Background technique [0002] Motors are used to drive various mechanical devices that require speed regulation, such as water pumps, fans, rolling mills, etc., and are widely used in iron and steel, metallurgy, light industry, textile, chemical, petroleum, construction and other industries. It is the main drive equipment, and its safe and reliable operation plays a vital role. It needs to monitor and protect the motor, and the temperature measurement junction box plays this important role. [0003] As a part of low-voltage and high-voltage three-phase asynchronous motors, the temperature-measuring junction box is mainly composed of bearing temperature-measuring elements and winding temperature-measuring elements. The function of the bearing and winding...
