Description
Technical Field
The utility model relates to the technical field of temperature detection, in particular to a bearing bush temperature sensor of power generation equipment.
Background
The generator is composed of main components such as a rotor, a stator, a frame, a thrust bearing bush, a guide bearing bush, a cooler, a brake and the like, wherein the thrust bearing and the guide bearing are combined with a contact component of the stator (a static component) and the rotor (a rotating component), and support and guide of the rotating component are achieved. The thrust bearing bush is called a thrust bush for short, the guide bearing bush is called a guide bearing bush for short, and the thrust bearing bush and the guide bearing bush are called bearing bushes for short. The safety, stability and reliability of the whole assembly are largely determined by the bearing bushes.
The rotor of the large-sized generator can weigh thousands of tons, for example, a single-machine capacity 70-kilowatt hydropower station of Lasiwa is 1263 tons, and a single-machine capacity 85-kilowatt hydropower station of Wu Dongde is about 2100 tons. The weight of the whole rotor is required to be supported by the push shoes and then rotated, and the vertical coaxial rotation is ensured by the guide shoes. The bearing bush is usually stationary and is in the shape of a tile-shaped semi-cylindrical surface, and is generally made of bronze, antifriction alloy and other wear-resistant materials, the contact surface with the rotor is very smooth, the contact surface of the rotor and the bearing bush is also provided as a very smooth mirror plate, and the rotor and the bearing bush are immersed in a closed oil tank at the same time. When the bearing bush is in operation, a layer of very thin oil film is arranged between the bearing bush and the mirror plate to play a role in lubrication and heat dissipation. If lubrication is poor or impurities are in oil, high temperature is generated by direct friction between the bearing bush and the rotating shaft, and the bearing bush is made of special high-temperature resistant alloy materials, but the high temperature generated by direct friction is still enough to burn the bearing bush out. And the temperature is too high due to the factors of too large load, too high oil temperature, impurity existence of lubricating oil, abnormal viscosity and the like, so that the tile burning is caused, and the tile burning belongs to a serious abnormal accident in the operation of a unit. If the emergency stop measures are not found to be adopted in time, the generator may have serious accidents such as locking of a clamping shaft, tooth cutting and shaft deformation, and even flying of a canteen. Therefore, the real-time temperature monitoring of the bearing bush by the machine set designer and the operation and maintenance personnel is very important, the real-time temperature of the bearing bush usually enters the system to participate in the protection systems such as accident pre-alarming or braking shutdown, and the like, and the mode can play a role in early warning of abnormal accidents or taking emergency measures to prevent important accidents.
At present, almost all generator sets adopt a platinum thermal Resistor (RTD) to monitor the temperature of a bearing bush in real time, the basic principle of the RTD is that the resistance value of platinum can rise along with the rise of the temperature, the manufacturing method of the sensor is to weld the platinum serving as a temperature sensing element on a wire, the working condition of the bearing bush is bad, and the sensor is always in the lateral impact and vibration environment of oil immersion and rapid oil flow, so that the sensor is easy to deteriorate or damage.
Current approaches such as temperature rise due to sensor performance degradation are not currently precluded; when the sensor is damaged, the sensor can be only stopped and removed for replacement, and the position can be changed to be only operated in a temperature blind area before stopping and overhauling; and even if the sensor is replaced by stopping, the sensor is replaced by detaching the oil tank and the bearing bush because the bearing bush is positioned in the oil tank and the wiring is complex, and the working procedure is complex.
