Technical Field

The utility model relates to the technical field of electronics, in particular to an improved circuit of a direct-current filter capacitor of a high-voltage and ultrahigh-voltage all-in-one machine.

Background

The high-voltage test refers to the test of the voltage resistance of various high-voltage and low-voltage electrical apparatus devices, insulating materials and insulating structures. The basic theory behind high voltage testing is that a product is exposed to a very harsh environment, and if the product can maintain normal conditions under such harsh environment, it can be determined that the product is working under normal environment, and the normal conditions can certainly be maintained. Different products have different specifications, and basically, a high voltage is applied to the product for testing at the time of high voltage testing, and the voltage must be maintained for a prescribed period of time. If the leakage current of a component is kept within a specified range within a specified time, the component can be determined to operate safely under normal conditions. Good design and selection of a good insulating material can protect the user.

The existing high-voltage transformers are placed in an external cart, are connected with a host machine through cables, are large in appearance, occupy space and are troublesome to move, and particularly, a high-voltage capacitor needs to be additionally connected during direct-current testing, as shown in figure 1.
