Description

Technical Field

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

[0002] The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings, of which the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils. It can transform AC voltage, current and impedance. A simple iron core transformer consists of an iron core made of soft magnetic material and two coils with different numbers of turns on the iron core. The role of the iron core is to strengthen the magnetic coupling between the two coils. In order to reduce the eddy current and hysteresis loss in the iron, the iron core is made of laminated painted silicon steel sheets; there is no electrical connection between the two coils, and the coils are wound with insulated copper wire (or aluminum wire).

[0003] Application number CN202221567047.2 provides an online monitoring device for power transformer noise, which belongs to the field of power system detection, including a pair of brackets, a pair of locking devices, a screw, a guide rod, and a noise monitor for collecting noise signals; a control device for processing and analyzing the collected noise signals; a drive device for driving the screw to rotate, installed on the bracket, and connected to one end of the screw; when in use, a pair of locking devices on a pair of brackets can be locked on a pair of side surfaces of the transformer, which is easy to install, and then the noise monitor can be automatically moved through the screw guide rod to find the maximum noise source and stop at the corresponding position for monitoring. Each time this application is used, only one side of the transformer can be monitored, and the transformer has four sides. If you want to complete the noise monitoring of the remaining sides, you can only disassemble the bracket and the locking device, which makes the monitoring operation complicated and reduces the monitoring efficiency.
