Description

Technical Field

[0001] The utility model relates to the technical field related to rectifier transformer temperature monitoring, in particular to a rectifier transformer temperature monitoring structure. Background Art

[0002] A rectifier transformer is a step-down transformer that reduces the voltage to the required level and then uses semiconductor tubes for rectification. The functions of a rectifier transformer include voltage conversion, current conversion, and improving the DC voltage waveform. Since the rectifier transformer generates a lot of heat during operation, in order to maintain the normal and stable operation of the transformer, it is necessary to use a temperature monitoring mechanism to monitor the transformer temperature in real time.

[0003] For example, announcement number CN220418664U discloses a rectifier transformer temperature monitoring structure, which relates to the technical field of transformers and includes a transformer housing, wherein the inner wall of the transformer housing is provided with a rectifier transformer body. In the utility model, a single chip computer stores a preset temperature value, which is used to compare with the current temperature value transmitted by the first temperature sensor and the second temperature sensor, respectively. When the actual value is higher than the preset value, it means that the temperature inside the transformer housing and the temperature of the coil core on the rectifier transformer body are higher, and a high temperature signal is transmitted to the substation control center through a signal transmitter to alert relevant staff in the control center, so as to facilitate relevant staff to timely understand the temperature inside the transformer housing and the temperature of the coil core on the rectifier transformer body, and relevant staff to take corresponding measures according to the temperature in time, thereby ensuring the normal operation of the rectifier transformer body and avoiding affecting the power supply;

[0004] However, the prior art has the problem that the installation and positioning of the temperature sensor is relatively inconvenient. Most of the installations require the use of bolts, which makes it inconvenient to disassemble, maintain, and replace the temperature sensor. Moreover, when the temperature sensor and the transformer coil core are used for temperature monitoring, the connection between the temperature sensor and the coil core is relatively inconvenient, making it inconvenient to place the temperature sensor close to or near the coil core for temperature monitoring. For example, the comparative patents listed above have this problem.

[0005] To this end, we propose a rectifier transformer temperature monitoring structure to solve the above problems. Utility Model Content

At the same time, the connecting plate 9 drives the fixing rod 11 to slide between the fixing plate 12, and the temperature sensor 6 is pressed and fixed by the connecting plate 9. Then, the fixing cap 13 threadedly connected to the outer surface of the fixing rod 11 is rotated so that the fixing cap 13 is fitted and set at the left end of the fixing plate 12, thereby facilitating the limiting of the fixing rod 11 and the fixing plate 12 to prevent the connecting plate 9 from loosening from the protrusion 7.
