Description

Technical Field

[0001] The utility model relates to the technical field of wireless temperature measurement, in particular to a wireless temperature measurement device. Background Art

[0002] The temperature monitoring points of high-voltage electrical equipment are all in an environment of high voltage, high current, and strong magnetic field. Some monitoring points are even in a closed space. Due to strong electromagnetic noise, high-voltage insulation, space limitations and other issues, conventional temperature measurement methods cannot solve these problems and cannot be used.

[0003] A wireless temperature measuring device proposed in Chinese utility model patent application number: CN201120475451.2. The wireless temperature measuring device includes: an insulating shell, a main control board, a power supply, a wireless transmission device and a temperature detector, wherein the power supply, the wireless transmission device and the temperature detector are respectively connected to the main control board; the main control board, the power supply, the wireless transmission device and the temperature detector are arranged in the insulating shell. By setting up the insulating shell, the wireless temperature measuring device can be placed in high-voltage equipment such as a high-voltage switch cabinet for use. The temperature detector can effectively detect the temperature in the high-voltage switch cabinet, and the main control board transmits the signal to the outside through the wireless transmission device.

[0004] However, the existing wireless temperature measuring devices have some shortcomings during use and still need to be improved. Traditional wireless temperature measuring devices usually directly fit the measured part with the power-collecting sheet to achieve temperature measurement and data transmission. However, this bonding method often has stability problems. Since the measured part is usually in a high temperature environment and there may be external factors such as vibration or impact, the fit between the power-collecting sheet and the measured part is prone to loosening, resulting in inaccurate temperature measurement or interrupted data transmission. Therefore, we have made improvements to this and proposed a wireless temperature measuring device. Utility Model Content

The electrical alloy sheet 501 is bundled and installed at the cable lap joint of the busbar and the isolating knife switch of the fixed high-voltage switch cabinet.

[0031] The wireless temperature measuring host 1 is wirelessly connected to the wireless temperature sensor 5.

[0032] The device's built-in wireless temperature sensor 5 is equipped with a highly sensitive temperature probe 502, which can measure the temperature in real time and accurately, and transmit the data to the temperature measurement host wirelessly. Its measurement range is wide, covering the temperature range from -25°C to +100°C, and the sampling frequency is high to ensure the real-time nature of the data.

[0033] The design of the electrical alloy sheet 501 enables it to be conveniently tied to the busbar static contact or the cable connection of the isolating knife switch of the removable or fixed high-voltage switch cabinet, realizing accurate temperature measurement at different positions. This design allows the device to be flexibly applied to various complex electrical environments.

[0034] The device uses wireless data connection to avoid layout restrictions and safety risks that may be caused by wired connection.

[0036] The working process of the utility model during use:

[0037] 1. Deployment and installation: The wireless temperature sensor 5 is bundled with the key parts of the high-voltage switch cabinet, such as the busbar static contact or the cable joint of the isolation switch, through the electrical alloy sheet 501, to ensure that the temperature probe 502 can directly contact the measured part and accurately obtain temperature information. The silicone sheath 503 is covered on the electrical alloy sheet 501, which not only plays a protective role, but also enhances the stability of the installation through the inner sheath thread 5031.

[0038] 2. Temperature measurement and acquisition: The temperature probe 502 senses the temperature changes of the contact point in real time and converts these changes into electrical signals. The wireless temperature sensor 5 collects and processes the temperature signal according to the set temperature measurement range and sampling frequency, such as -25℃~+100℃, 25 seconds / time.

[0039] 3. Wireless data transmission: The collected temperature data is sent from the wireless temperature sensor 5 to the wireless temperature measurement host 1 via wireless means such as 2.4GHz or 433MHz frequency.

The user can perform necessary operations on the device through the control button 4, such as adjusting the sampling frequency, viewing historical data, etc.

[0041] Working principle: The core of the wireless temperature measurement device lies in the combination of the wireless temperature sensor 5 and the temperature probe 502 of the electrometallic sheet 501. The electrometallic sheet 501 acts as a sensing element and senses the temperature of the contact point through the temperature probe 502 inside it. The temperature probe 502 converts the temperature change into electrical signals, which are then captured and processed by the wireless temperature sensor 5.

The signal conditioning circuit amplifies, filters and digitizes the electrical signal from the temperature probe 502 to obtain an accurate temperature value. Subsequently, the wireless communication module sends the processed temperature data to the wireless temperature measurement host 1 wirelessly.
