Description

Technical Field

[0001] This utility model relates to the field of fan temperature acquisition technology, and in particular to a connection structure and cable temperature monitoring device. Background Art

[0002] With the rapid development of the wind power industry, the installed capacity of wind power is constantly expanding, and the proportion of wind power in the power grid is getting higher and higher. Therefore, the requirements for the safe and reliable operation of wind turbines are also getting higher and higher. The main equipment of wind power generation includes wind turbines, transformer substations and main transformers. The space of the wind turbine nacelle is small and various equipment is densely packed. Continuous operation will cause the temperature of the lubricating oil in the equipment and gearbox to rise, resulting in changes in the characteristics of the lubricating oil, accelerated wear of equipment, and accelerated aging of electrical components, which will bring potential faults to the normal operation of the wind turbine. Therefore, monitoring the temperature of each component and lubricating oil of the wind turbine generator set, ensuring that they operate within the normal range, and ensuring that the measured parameters are accurate and reliable are necessary guarantees for the normal and stable operation of the wind turbine. At the same time, whether the pressure and level of the gearbox lubricating oil are normal is also related to the lubrication effect and the normal operation of the wind turbine.

[0034] When in use, select the appropriate connection slot 201 according to the cable size, place the cable into the connection slot 201, and then install and fix it through the clamping through hole 203 on the clamping cover plate 204 and the fastener. After fixing the cable and the plug-in connector 202, the internal fixation of the temperature measuring contact 207 will be released, so that the temperature measuring contact 207 can come into contact with the cable through the internal through hole to perform temperature monitoring.

[0035] Example 2

[0036] Reference Figure 3 and Figure 4This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a connection structure, which solves the problem that temperature cannot be directly collected on the cable.
