Description

Technical Field

[0001] The utility model relates to the technical field of transformer protection, in particular to a transformer oil draining and nitrogen injection protection device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of an iron core and windings. The iron core is the main magnetic circuit part of the transformer, usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content. Nitrogen injection protection is a safety protection method that injects nitrogen into a specific area to reduce the oxygen concentration to achieve fire prevention, explosion prevention, temperature reduction and other goals. This method is commonly used in multiple scenarios such as power, mining, and laboratories.

[0003] A transformer oil draining and nitrogen injection protective device with announcement number CN 208865083 U uses a fixing device to fix the middle part of a nitrogen bottle to prevent it from shaking, and then uses a connecting device to connect the nitrogen bottle and a connecting pipe, which facilitates the connection between the two and improves the sealing of the connection, thereby improving the sealing and stability of the transformer oil draining and nitrogen injection protective device.

[0004] The transformer oil draining and nitrogen injection protection device fixes the nitrogen cylinder by means of a fixing device to prevent the nitrogen cylinder from being damaged when the transformer is impacted by external force. However, the device is only provided with a device for fixing the nitrogen cylinder, and no device for buffering and protecting the nitrogen cylinder is provided. When the transformer is impacted by external force and the nitrogen cylinder is squeezed, the nitrogen cylinder is prone to cracking. When the nitrogen cylinder cracks, it is prone to explosion, so improvement is needed. Utility Model Content
