Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor used for electric power equipment. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. It is the core part of a temperature measuring instrument. It is divided into two categories: thermal resistors and thermocouples according to the sensor material and electronic component characteristics. The temperature measurement of power equipment needs to consider some special environments such as insulation and strong electromagnetic interference. Therefore, traditional temperature measurement methods such as thermocouple temperature sensors and thermistor temperature sensors are susceptible to interference. Compared with traditional sensors, fiber grating temperature sensors have the advantages of high sensitivity, small size, anti-electromagnetic radiation, long-term stability and long signal transmission distance.

[0003] The existing fiber grating temperature sensors are not convenient and stable to install and fix, which may cause the optical fiber to break, making it impossible to measure the temperature of the power equipment, which may cause the power equipment to be damaged due to overtemperature, greatly increasing the cost of repairing or replacing the damaged power equipment. In addition, the fiber grating temperature sensors are easily corroded and cannot meet the requirements of working under such harsh conditions.

[0004] Therefore, there is an urgent need to provide a temperature sensor for electric power equipment to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing fiber grating temperature sensor is not convenient and stable to install and fix, which may cause the optical fiber to break, making it impossible to measure the temperature of the power equipment, which may cause the power equipment to be damaged due to excessive temperature, greatly increasing the cost of repair or replacement due to damage to the power equipment, and the fiber grating temperature sensor is easily corroded and cannot meet the requirements of working under such harsh conditions.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a temperature sensor for electric power equipment, including an alarm mechanism, a protective cover is installed on one side of the alarm mechanism, a temperature measuring optical fiber is fixedly connected to the inner surface of the protective cover, and a connecting mechanism is installed on one side of the protective cover.

Under normal temperature, the display screen is used to display the temperature of the power equipment and the remaining power of the alarm mechanism. After the protective cover is threadedly connected to the installation pipe, when the temperature is too high, the alarm light turns red, and an alarm sounds to remind the staff to shut down the power equipment in time and conduct subsequent inspections and repairs. When the power of the alarm body is lower than the warning range, the alarm light turns yellow, and an alarm sounds to remind the staff to replace the battery of the alarm body in time to avoid the failure to detect the temperature of the power equipment due to power outages. The temperature is displayed in real time on the display screen and used in conjunction with the alarm light to ensure that the power equipment will not be damaged due to excessive temperature, thereby reducing the cost of repair or replacement due to damage to the power equipment.

[0012] Through the above technical solution, the rubber outer skin is soft, not easy to deform after bending, and has good resilience, which can effectively protect the temperature measuring optical fiber from being damaged due to bending. The rubber sleeve is insulated and sealed, and will not leak electricity or get water in, which greatly ensures the life safety of the staff.

The installation is convenient and the fixing effect is good. When in use, the temperature probe transmits the received temperature to the temperature measuring optical fiber, and the temperature measuring optical fiber converts the heat signal into an optical signal after processing and finally transmits it to the alarm body. The real-time temperature is displayed on the display screen. For the temperature measurement of power equipment, some special environments such as insulation and strong electromagnetic interference need to be considered. Therefore, the traditional temperature measurement methods of thermocouple temperature sensors and thermistor temperature sensors are susceptible to interference and cannot meet the requirements of working under such harsh conditions. Compared with traditional sensors, fiber grating temperature sensors have the advantages of high sensitivity, small size, anti-electromagnetic radiation, long-term stability and long signal transmission distance.
