The invention provides a wireless temperature detector without a power supply. The wireless temperature detector comprises a water storage device, a heat release device, a heat absorption device, a semiconductor thermoelectric power generation sheet and a wireless signal transmitter, the water storage device tightly attached to the measured object comprises a water storage shell, a first water outlet in the bottom of the water storage shell is communicated with the heat release device, and a second water outlet is communicated with the heat absorption device. A water-soluble heat release substance is arranged in the heat release device, and a water-soluble heat absorption substance is arranged in the heat absorption device. The heat release device is tightly attached to the hot face of thesemiconductor thermoelectric power generation piece, the heat absorption device is tightly attached to the cold face of the semiconductor thermoelectric power generation piece, the semiconductor thermoelectric power generation piece is connected with the wireless signal transmitter, and the wireless signal transmitter is used for transmitting early warning signals after being powered on. The temperature detector provided by the invention has no power supply, does not need to be equipped with dry batteries, lithium batteries and other active power supplies or wired power supplies, and reducesa large amount of manpower periodic maintenance cost compared with the prior art.
Description
technical field [0001] The invention relates to the technical field of temperature detection, in particular, the invention relates to a wireless temperature detector without power supply. Background technique [0002] In the industry and power industry, the normal operation of electrical equipment ensures the normal operation of the society and the normal life of the people, so the reliability of the equipment is very important. Many enterprises advocate preventive maintenance of equipment, and temperature is the most important monitoring parameter in preventive maintenance. Excessive temperature means the possibility of failure. On-line temperature monitoring is an important means to ensure the safe operation of high-voltage equipment. [0003] High temperature overheating directly leads to the decline of mechanical strength and physical properties of electrical materials, and the increase of contact resistance value. In the continuous flow state, the oxidation of the conn...
