Detailed ways

The following is a specific embodiment of the present invention, and the present invention will be further described in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, a wireless temperature measuring device for a high-voltage switchgear is composed of a temperature acquisition module 1 composed of an embedded processor 12 and a temperature sensor 11 connected to it for measuring the temperature of a high-voltage contact, and embedded The processor 12 is connected to the wireless communication module 2 for sending temperature information to the control center 3 through wireless communication, and the power supply module 4 for supplying power to the temperature acquisition module 1 and the wireless communication module 2, the temperature acquisition module 1, The wireless communication module 2 and the power supply module 4 are installed on the fixed part 5 made of heat-conducting material, so that the temperature sensor 11 is in direct contact with the fixed part 5. The fixed part 5 is provided with an internal threaded hole 6, and the fixed part 5 passes through Hole 6 is installed on the high-voltage contact of the high-voltage switchgear of the substation. Wherein, what the temperature sensor 11 adopts is a DS18B20 digital temperature sensor, and what the embedded processor 12 adopts is a STM8L152 chip. The wireless communication module 2 uses a CC2500 high-performance wireless transceiver, the power module 4 uses a high-energy lithium battery, and the control center 3 is an operation and maintenance center and/or mobile phones of staff.

During work, the fixed part 5 of the wireless temperature measuring device has an internal threaded hole 6, and the wireless temperature measuring device can be installed on the high-voltage contacts in the high-voltage switch cabinet of the substation, one for each of the three phases A, B, and C. The temperature of the high-voltage contact is transmitted to the temperature sensor 11 through the fixed part 2. The temperature sensor 11 is connected to the embedded processor 12 and directly contacts with the fixed part 5. Because the fixed part 5 is a heat-conducting material, the temperature sensor can detect the high-voltage contact. point temperature. The embedded processor 12 regularly reads the temperature data of the temperature sensor 11, and sends it to the control center 3 through the wireless communication module 2, and the control center 3 can send corresponding instructions to obtain temperature information in real time. The control center 3 is the operation and maintenance center and/or staff mobile phones. The operation and maintenance center is equipped with temperature monitoring software, which can visually see the temperature data and temperature change curve. When the temperature rises too fast or exceeds the alarm temperature, the monitoring software will Automatically send out sound and light alarms for timely processing and troubleshooting hidden troubles. In addition, staff can check the temperature information of high-voltage switchgear in real time through mobile phones. The invention provides technical means for real-time temperature monitoring of unattended substation high-voltage switch cabinets. And the installation is simple, firm and reliable, which improves the working life and stability of the equipment.
