Moudle Type of High Voltage DC Generator

Model

ZDYK-K

Structure

Type K modular structure

The system has a parallelogram (delta-delta) structure. Two sections make up a level and form a fixed modular unit, each unit is placed in a container for fast transportation and dismounting.

Application

Applicable to the DC insulation withstand test of high-voltage electrical products on site or in field.

Advantages

Artistic appearance

As shown in the figure.

Convenient transportation

Standard container is provided, which enables transportation, assembly and dismantling anytime and anywhere.

Fine tightness of high-voltage silicon stack

A unique high-voltage silicon stack assembly technology is employed to guarantee no oil leakage all year around.

Excellent field strength design

Grading ring adopts whole cap structure with smooth surface and without edge angle, its field strength is smaller than that of flake-type or tube-type ones of the same sizes; or under the same field strength, the size of the grading ring is smaller than that of the flake-type or tube-type ones, which can save space.

Simple operation

Touch screen, which is simple, visual and easy to operate, is used as the control interface of the host computer.

Reliable action

All control elements are products of international brands, which makes the PLC control system stable and reliable.

Strong anti-interference capability

Fiber isolation technique is used for the control system.

Performance

Ripple coefficient

Polarity switching time of silicon stack

Switching time of voltage polarity

Actuating time of grounding switches

Accuracy of DC-resistive voltage divider

Uncertainty of measuring system

Integrated structure is employed for charging device, main body and grounding switch assembly of the DC voltage generator.

Unilateral double voltage rectification circuit is used as the charging circuit.

The general structure design is reasonable with stable mechanical structure and strong shock resistance.

Good rainproof and anti-UV capacity by applying silicone rubber skirt for the external insulation.

This series of products are the initiative ones of BHT in China and have become the indispensable main equipment in on-site commissioning test of DC high-voltage electrical products.
