Description

Technical Field

[0001] The utility model relates to the technical field of transformer monitoring, and specifically relates to a transformer condition monitoring device. Background Technique

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] Among them, the "transformer condition monitoring device" disclosed in the publication number "CN219641121U" is also an increasingly mature technology. It "includes an installation box, and box doors are arranged on both sides of the front of the installation box. An alarm is fixedly installed on the right side of the top of the installation box. Under the action of a temperature sensor, the temperature inside the installation box is monitored, and the monitored temperature data is transmitted to a control box. The control box will preset a standard temperature data. After receiving the temperature data transmitted by the temperature sensor, the control box analyzes and processes the monitored temperature data. When the temperature value monitored by the temperature sensor is higher than the preset temperature value, the control box will control the alarm to sound an alarm. At the same time, it solves the problem that when the transformer is working, due to the large amount of heat generated by the transformer, the temperature inside the transformer is relatively high. The existing transformers do not have the function of monitoring the temperature inside them. When the transformer temperature is relatively high, it is easy to cause damage to the electrical components inside the transformer, resulting in transformer failures.

[0004] However, the design of the above monitoring device has the following disadvantages: For the temperature monitoring of this type of transformer, fixed temperature monitors are set on the outside of the transformer, and it is impossible to adjust up and down and adjust the orientation, so that the range of temperature monitoring inside the transformer protection box is limited, resulting in unstable operation of the transformer and damage to the transformer due to failure to cool down in time when the temperature is too high.

[0005] Therefore, it is necessary to provide a transformer condition monitoring device to solve the above problems. Content of the Utility Model
