Abstract
The utility model relates to a high-power three-phase alternating-current switch which comprises a polybutylene terephthalate packaging shell and a copper base plate plastically packaged on the bottom inside the shell, wherein DCBs are welded on the copper base plate and in the packaging shell, seven one-way thyristors are welded on each DCB and are in reverse parallel connection, the gate pole of each one-way thyristor is led out of the packaging shell by a gate pole control terminal, and six outer electrodes of the seven one-way thyristors are led out of the packaging shell from two sides of each DCB. By adopting the structure, the high-power three-phase alternating-current switch has high integration degree; and as the silicon controlled components are packaged in the PBT (polybutylene terephthalate) shell, the volume of products is reduced, and mutual interference is less; and the high-power three-phase alternating-current switch has stable performance, and is extremely applicable to medium-power and high-power occasions with higher condition.
Description
Technical field
The utility model relates to a kind of three-phase alternating current switch, especially a kind of high-power three-phase alternating current switch of microencapsulated.
Background technology
The three-phase alternating current switch is mainly used in occasions such as motor adjusting.At present, the product that will realize function of the same race on the market all can only adopt the interconnective mode of a plurality of single phase alternating current (A.C.) switches, volume ratio is bigger on the one hand for this structure, therefore required occupation space is also bigger, also comparatively complicated during installation, and the phase mutual interference is easy to generate than multiple harmonic, has a strong impact on the use of product, and reliability is not high yet.
The utility model content
The technical problems to be solved in the utility model is: a kind of stable performance, the small and exquisite high-power three-phase alternating current switch of volume are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of high-power three-phase alternating current switch, comprise polybutylene terephthalate (PBT) package casing and the plastic packaging copper soleplate of bottom in the enclosure, on the described copper soleplate, be welded with the DCB plate in the package casing, be welded with 7 one-way SCRs on the DCB plate, described 7 one-way SCRs are done inverse parallel and are connected, the gate pole of each one-way SCR is drawn out to the outside of package casing by the gate pole control terminal, and described 7 one-way SCRs are drawn the outside of 6 external electrodes to package casing from the both sides of DCB plate.
Further, in order to increase aesthetic property and symmetry, and save the space of installing, with the drawing of 3 of every sides, the exit turnover of described external electrode is arranged on the top of package casing to 6 external electrodes described in the utility model from the both sides of DCB plate.
Further, the nearly two ends of copper soleplate described in the utility model are provided with the circular mounting hole, like this can be according to the different convenient installation of position when the utility model is installed.
The beneficial effects of the utility model are, solved the defective that exists in the background technology, structure described in the utility model makes powerful three-phase alternating current switch have high integration, and the one-way SCR device package has been reduced small product size in the PBT shell, the phase mutual interference is few, stable performance, the higher middle large-power occasions of the condition that is highly suitable for is used.
