Description

Technical Field

[0001] The utility model relates to the technical field of voltage transformer monitoring devices, in particular to a voltage transformer monitoring device. Background Art

[0002] The voltage transformer can realize the function of converting high voltage into low voltage in proportion. It is a transformer with an iron core, mainly composed of primary and secondary coils, an iron core and insulation. When a voltage U1 is applied to the primary winding, a magnetic flux φ is generated in the iron core. According to the law of electromagnetic induction, a secondary voltage U2 is generated in the secondary winding. By changing the number of turns of the primary or secondary winding, different ratios of primary voltage to secondary voltage can be generated, which can form voltage transformers with different ratios. Considering that the performance of the voltage transformer will affect the power consumption effect and safety, it is often necessary to install a voltage transformer monitoring device connected to it to achieve monitoring and protection. However, this type of monitoring device still has some defects in actual operation.

[0003] Voltage transformer monitoring devices can generally only monitor the output voltage of a single voltage transformer. They cannot automatically collect the input current, input voltage and output voltage of multiple voltage transformers for modular monitoring and protection, nor are they easy to achieve real-time and remote alarms, which affects the monitoring accuracy and coverage, and makes it difficult for staff to respond in a timely manner. Furthermore, they often only use heat dissipation holes and fans for heat dissipation protection, which has great limitations and low heat dissipation efficiency, thus affecting the service life of the device.
