Description

Technical Field

[0001] The utility model relates to the field of temperature measurement, in particular to a wireless temperature measuring instrument with a power supply constructed by a photovoltaic cell. Background Art

[0002] A large number of devices in power systems require temperature monitoring to determine their operational status, allowing operators to take timely action to eliminate anomalies and effectively prevent damage and accidents. For example, busbar connection points, various switches, circuit breakers, main transformer bushing clamps, and high-voltage cable connectors are prone to poor contact due to climate fluctuations, material aging, corrosion, and looseness. High currents passing through these points can easily damage the equipment, and in severe cases, even cause fires and explosions. Furthermore, when performing temperature monitoring on certain power system devices, power supply issues for sensors and signal transmission lines can hinder temperature measurement.

[0003] However, although the existing data transmission method has strong anti-interference ability, it requires the special laying of communication lines, which increases the cost of laying lines and brings difficulties to the wiring of switch cabinets. Therefore, it is very necessary to study reliable wireless transmission methods. When monitoring the temperature of equipment in the switch cabinet in real time, there are problems such as high cost of monitoring sensor power conversion equipment, inconvenient data wired transmission wiring, and imperfect online real-time monitoring of data and management software.

[0004] Therefore, in view of the increased line laying cost caused by the above-mentioned wired data transmission, a wireless temperature measuring instrument with a power supply constructed by photovoltaic cells can be designed, and the cost of power supply conversion equipment for monitoring sensors can be reduced by using a wireless transmission structure.

It has the advantages of being pollution-free, low energy consumption, small size, high reliability, easy installation, and simple maintenance, and can achieve medium- and long-distance data transmission with low power consumption.
