Description

Technical Field

[0001] The utility model relates to the technical field of power transformers, in particular to a high-voltage power transformer used for capacitor voltage division. Background Art

[0002] The high-voltage power transformer used for capacitor voltage division is also known as the power transformer. It is a soft magnetic electromagnetic component that provides power transmission, voltage conversion, and insulation isolation for the power supply. It is widely used in the power supply and power fields. Its working principle is similar to that of an ordinary transformer. Both use electromagnetic induction to change the AC voltage. Most daily electrical appliances use power transformers to increase or decrease the voltage to meet their own operating requirements.

[0003] In the prior art, an authorized patent with publication number CN 221507887 U discloses a power transformer, comprising a power transformer main body and a pin arranged at the bottom of the power transformer main body, a base installed at the bottom of the power transformer main body, a connecting terminal matched with the pin provided inside the base, upper threaded blocks fixedly connected to both sides of the power transformer main body, lower threaded blocks corresponding to the upper threaded blocks fixedly connected to both sides of the base, and fixing sleeves connected to the outer sides of the upper threaded blocks and the lower threaded blocks by threads. The utility model eliminates the need to solder the power transformer main body to a circuit board by providing the pin, upper threaded block, lower threaded block, fixing sleeve and connecting terminals, thereby facilitating subsequent disassembly, maintenance or replacement of the power transformer main body, and facilitates heat dissipation of the power transformer main body by providing the heat dissipation holes and empty slots, thereby preventing heat from accumulating between the power transformer main body and the base, causing excessive temperature and reducing the service life of the power transformer main body.

[0004] However, the above technical solution still has the following shortcomings when in use: the base of the above device is only fixedly mounted on the circuit board through multiple connection terminals, so that when the power transformer body is disassembled and assembled, the connection terminals are easily disconnected from the circuit board due to the shaking of the base, and the base only dissipates heat to the power transformer body through the provided heat dissipation holes and empty slots, and the heat dissipation effect is very limited. In this regard, we propose to use a capacitor voltage divider high-voltage power transformer to solve the above-mentioned problems. Utility Model Content
