Embodiment 1

[0015] Install a temperature measurement module on the busbar of the ring network cabinet for three-phase temperature measurement. The temperature measurement signal is sent to the receiving module through signal encoding. After converting the analog signal into a digital signal, the temperature measurement digital signal is encoded using the Internet of Things transmission technology - Zigbee Send it to the data analysis and processing module. After the information is stored by the data analysis and processing module, the three-phase temperature comparison of each circuit in the ring main unit and the ambient temperature comparison and the temperature comparison between the circuits are carried out. If the temperature of one phase in the ring main unit is higher than The temperature of the other two phases of the circuit is much higher or the temperature of the three phases of one circuit is much higher than the temperature of the other three phases of the circuit, then the dat...

Embodiment 2

[0017] The temperature measurement module is installed on the cable head of the power distribution cabinet for three-phase temperature measurement. The temperature measurement signal is sent to the receiving module through signal encoding. After converting the analog signal into a digital signal, the temperature measurement digital signal is transferred using the Internet of Things transmission technology - Zigbee. The code is sent to the data analysis and processing module, and the information is stored by the data analysis and processing module to compare the three-phase temperature of each circuit in the power distribution cabinet with the ambient temperature and the temperature comparison between the circuits. If the temperature of the other two phases of the circuit is much higher or the temperature of the three phases of one circuit is much higher than the temperature of the other three phases of the circuit, the data analysis and processing module judges that the phase or...

Abstract

The invention discloses a power equipment remote intelligent on-line temperature measurement system. A temperature measurement module installed at a power equipment implicit connection part is utilized to carry out three-phase temperature measurement, a temperature measurement signal passes through a signal coding sending and receiving module, after an analog signal is converted into a digital signal, by utilizing Internet of things transmission technology Zigbee, a temperature measurement digital signal code is sent to a data analysis processing module, after data analysis processing module stores information, three-phase temperature comparison and ambient temperature comparison of each loop and temperature comparison between loops in equipment are carried out, if temperature of a phase is higher than temperature of the other two phases or three-phase temperature of a loop is higher than three-phase temperature of other loops, the data analysis processing module determines that the phase or a loop connection position has heating abnormity, a remote communication module carries out remote transmission of data obtained by the data analysis processing module to a data display module and a heating alarm module, and the data display module and the heating alarm module carry out heating information data displaying and alarming at a remote terminal.

Description

[0001] technical field [0002] The invention belongs to the technical field of electric equipment maintenance, and in particular relates to a remote intelligent online temperature measurement system for electric equipment. Background technique [0003] With the economic development and environmental requirements of cities, cable lines and equipment are more and more widely used in urban distribution networks. As the weak link of the safe and reliable operation of the power grid, the busbar and cable head not only depend on the material of the cable head and busbar, but also depend on the connection construction process of the busbar and cable head, and are also related to the timely load. If the 10kv switchgear, ring network cabinet, switch cabinet, power distribution cabinet and other internal bus bars or cable heads generate heat due to factors such as design, construction technology, and overload, but they are not inspected or monitored in time and the load continues to ...
