Description
Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to an anti-seismic structure of transformer equipment. Background Art
[0002] The three-winding transformer consists of a primary winding, a secondary winding and a tertiary winding, and also includes an iron core. The iron core is usually made of laminated silicon steel sheets, which is used to concentrate the magnetic field to enhance the electromagnetic induction effect. The primary winding is connected to the input power supply, the secondary winding is connected to the output load, and the tertiary winding is an optional additional winding used for specific electrical functions. The working principle of the three-winding transformer is similar to that of an ordinary transformer. The voltage conversion is achieved through electromagnetic induction. When an alternating current is passed through the primary winding, the magnetic field generated passes through the iron core and is induced into the secondary winding, thereby generating an induced voltage in the secondary winding to achieve voltage rise and fall. The tertiary winding may be used for specific regulation or control functions. Three-winding transformers are usually used in situations where additional functions or special applications are required. For example, they may be used to couple different circuits, achieve regulation, provide additional electrical protection, or achieve other special functions.
[0003] When the transformer vibrates or collides, the internal primary winding, secondary winding and tertiary winding are prone to contact and collision. The vibration or collision may cause the insulation layer between the primary winding, secondary winding and tertiary winding to be damaged or ruptured, causing a short circuit or grounding fault between the primary winding, secondary winding and tertiary winding. The contact and collision between the windings may change their electrical connection or cause a short circuit in the loop, thereby reducing the electrical performance of the transformer and affecting its normal operation. The contact between the windings will increase resistance, resulting in more heat loss, causing excessive temperature rise of the transformer, and even causing safety problems such as fire.
