Abstract
A DC voltage generator relates to an HVDC test line section and the power technology field of a corona cage. The DC voltage generator comprises a transformer, a DC output device and a residue power grounding device; the DC output device comprises three groups of insulation pipes which are vertically arrangd; adjacent insulation pipes in each group of insulation pipes are connected in series by a linking seat; each insulation pipe is respectively provided with a capacitor, the two ends of which are respectively and electrically linked with linking seats at the two ends of the insulation pipe, wherein each insulation pipe in one group of insulation pipes is respectively linked with the linking seats at the two ends of each insulation pipe of the other two groups of insulation pipes by a polar silicon stack. The invention has a three-colume type structure, and can adapt to the harsh environment requirement, with big output current being up to 0.5A, thus meeting the requirement on big current; the three-colume type structure can also achieve the requirement of wind and shake resistance, and can be used as an HVDC test line section and the outdoor power of the corona cage.
Description
Technical field
The present invention relates to the power technique fields of HVDC TEST line segment and corona cage.
Background technology
Existing DC voltage generator only limits to indoor use, output current is less than 50mA, output voltage all is a unipolarity, structure substantially all constitutes with two pole structures, monolateral charging, output current is little, in the face of the growing extra-high voltage electric power cause of China, can not satisfy the demand of electric utility with regard to the technology of existing product.
Summary of the invention
The object of the invention is to design a kind of outdoor high pressure, heavy DC voltage generator of can be used for.
The present invention includes a transformer, the 1200kv0.5A DC output devices is set, surplus electrical grounding assembly is set in a side of described DC output devices in transformer one side; Described DC output devices comprises three groups of upright insulation tubes to layout, each is organized between the insulation tube adjacent in the insulation tube and is connected in series mutually by connection seat, capacitor is set respectively in each insulation tube, the two ends of each capacitor connection seat at the insulation tube two ends by lead and place respectively electrically connect, wherein each insulation tube in one group of insulation tube respectively the connection seat at each the insulation tube two ends by two groups of insulation tubes of polarity silicon stack and other connect; Insulation tube in top joins a body overhead guard altogether by connection seat, series direct current output protection resistance on the body overhead guard.
It is the three pillar type structure that the present invention changes former two pole structures, adapt to harsh environmental requirement, characteristics as high height above sea level, infrabar, intensive ultraviolet, round-the-clock outdoor test of long duration operation, output current is big, reaches 0.5A, thereby satisfies the requirement to big electric current, the three pillar type structure, can also reach the requirement of wind resistance antidetonation, the outdoor power system that can be used as extra-high voltage direct-current test line segment and corona cage uses, and uses as the DC break down voltage and the scientific research of power product.
Surplus electrical grounding assembly of the present invention is provided with pneumatic grounding switch, and every group of pneumatic grounding switch is connected in parallel on respectively on the corresponding resitstance voltage divider.
The present invention also increases by a cover Pneumatic grounding device, and discharge need be manually gone in this equipment discharge in the past, and promptly inconvenience is dangerous again, behind the increase Pneumatic grounding device, can discharge to outdoor equipment in the observing and controlling chamber.
