Description

Technical Field

[0001] The utility model belongs to the technical field of mutual inductors, and more specifically, particularly relates to a comprehensive electromagnetic voltage mutual inductor. Background Art

[0002] Electromagnetic voltage transformer is an electrical device used to measure high voltage. It is mainly used to measure voltage, monitor voltage waveform and amplitude, protect power system, test equipment, etc. At the same time, it can also provide power to relay protection devices. However, when using traditional voltage transformers, they are often exposed to the external environment and will be directly affected by weather changes. When encountering severe rainstorms, the erosion of rainwater may cause the device to get damp. If it is used in a damp state for a long time, it is easy to cause chronic damage to its internal precision components and structures, which will cause the transformer's measurement accuracy to decrease. Long-term loss will also reduce the service life of the transformer, seriously affecting the stability and safety of the entire power system or related fields. Utility Model Content

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

The protective cavity provided by the heat dissipation fans 41 can effectively contact the outside air. When the transformer body 21 generates heat during operation, the heat dissipation fan 41 can be quickly operated to discharge the hot air in the protective cavity, and at the same time, fresh cold air from the outside is sucked in to form a good air circulation, thereby timely and effectively dissipating the heat generated by the transformer body 21 during operation, ensuring that it can operate stably and extending the service life of the transformer body 21.

[0025] The heat dissipation assembly also includes a filter 43. Blocks 44 are provided on both sides of the protective shell 31. The filter 43 can be clamped in the block 44 and detachably connected to the block 44 by screws. The filter 43 can effectively prevent dust and impurities in the outside air from entering the protective cavity, preventing these impurities from damaging the transformer body 21 and other internal components. At the same time, the detachable connection method facilitates the regular cleaning and replacement of the filter 43 to ensure that its filtering effect is always in good condition.

[0026] like Figure 2 , 3As shown, two groups of mounting cross plates 12 are arranged above the mounting base 11, providing a support structure for the installation and fixation of the transformer body 21. Positioning through holes 13 are provided at both ends of the mounting cross plates 12.

Multiple groups of insulating plates 37 are also provided on one side of the protective plate 36, and the insulating plate 37 is located between the two groups of secondary windings 23. The insulating plate 37 can effectively enhance the insulation performance between the windings, prevent short circuits or other adverse effects between different windings, and improve the safety and reliability of the operation of the transformer body 21.

[0029] The top surface of the top cover 32 is provided with two groups of inclined surfaces 38, and multiple groups of guide grooves 39 are provided on the inclined surfaces 38.
