Embedded type thermal resistor for motor of nuclear power station

Abstract

Disclosed is an embedded type thermal resistor for a motor of a nuclear power station. The embedded type thermal resistor comprises a cable and a copper foil, wherein the cable is positioned on the inner side of the copper foil; an adhesive tape is arranged on the exterior of the copper foil; an adhesive sheet is arranged between the copper foil and the cable; and a temperature sensing element is arranged on the inner side of the adhesive sheet. By setting the temperature sensing element in the resistor, the temperature change condition of the motor can be known in time; an adhesive plate is arranged outside the cable, so that the cable can be further protected from being broken, thereby prolonging the service life of the resistor; and in addition, a welding point copper sheet is arranged beside the temperature sensing element, so that the fixation of the temperature sensing element is firmer.

Description

technical field [0001] The invention relates to a resistor, in particular to an embedded thermal resistor for a nuclear power plant motor. Background technique [0002] There are many motors in operation in nuclear power plants. Some embedded thermal resistors for motors in nuclear power plants are suitable for platinum thermal resistors used for temperature measurement of motor windings and motor cores. There are also some temperature measuring devices that need to measure temperature. In these testing Some resistors also need to be used in the temperature device. At present, the embedded thermal resistors for motors are generally installed between the upper and lower windings in the motor slot. After the motor is installed, it needs to be dipped in paint. However, the thermal resistors are immersed in the paint after dipping. In the future, the maintenance will not be able to be replaced, only the rectification coil can be replaced, which increases the use cost of the moto...

Some embedded thermal resistors for motors in nuclear power plants are suitable for platinum thermal resistors used for temperature measurement of motor windings and motor cores. There are also some temperature measuring devices that need to measure temperature. In these testing Some resistors also need to be used in the temperature device. At present, the embedded thermal resistors for motors are generally installed between the upper and lower windings in the motor slot. After the motor is installed, it needs to be dipped in paint. However, the thermal resistors are immersed in the paint after dipping. In the future, the maintenance will not be able to be replaced, only the rectification coil can be replaced, which increases the use cost of the motor, and the resistance cannot be easily replaced and installed, which reduces the work efficiency of the operator
