Embodiment 1

[0029] From attached figure 1 It can be seen from -4 that the present invention relates to an insulation method for an IGCT transformer. An epoxy board 3 is inserted between the primary side 1 and the secondary side 2 of the IGCT transformer as an insulation isolation layer, and the IGCT transformer and the PCB board 5 are connected simultaneously. Put it into a plastic shell 4, and use insulating glue 6 to fill and cure it.

[0030] As a further improvement of the present invention, there are four input pins 7 on the top of the shell 4, and four output pins 8 on the bottom. Because the voltage and current are relatively large, the wiring pins are respectively embedded in the shell so as to be isolated from each other; The transformer pins are welded to the shell inserts and then treated with insulating glue. This shell not only plays a good role in bridging, but also fixes various components to play a role of shockproof, dustproof and waterproof.

[0031] As a further improv...

Abstract

The invention discloses an insulation method and device for an IGCT (integrated gate commutated thyristor) transformer. An epoxy plate is inserted between a primary side and a secondary side of the IGCT transformer to be used as an insulated isolation layer, and the IGCT transformer and a PCB (printed circuit board) are placed into a plastic housing, and sealed with insulation glue and solidified. Four input pins are arranged on the housing, and four output pins are arranged below the housing, and connection pins are respectively embedded into the housing due to relatively large voltage and current, so that the connection pins can be isolated from each other; and pins of the transformer are sealed with the insulation glue after being welded on insertion pieces of the housing, so that the housing can be well used for bridging, each of elements and components can be fixed, and shockproof, dustproof and waterproof effects can be achieved.

Description

technical field [0001] The invention relates to an insulation method and component structure of a transformer, in particular to an insulation method and a shell structure of an IGCT transformer. Background technique [0002] IGCT has the characteristics of large current, high blocking voltage, high switching frequency, high reliability, compact structure, low conduction loss, etc., and has low cost and high yield, so it has a good application prospect. It has been applied to power system grid devices (100MVA) and medium-power industrial drive devices (5MVA). IGCT has been successfully used in the field of medium-voltage variable-voltage inverters for many years. The transformer provides a safe and stable power supply for the IGCT drive. [0003] The IGCT transformer is an important component of the IGCT. It provides a sufficiently stable power supply for the IGCT drive. If the transformer fails, it will directly cause the drive to fail to work. Therefore, it is essential to...
