CDLD Impulse Current Generator For Test Residual Voltage And Motion Load Of Valve Discs

Product

D type impulse current generator

Type

CDLD

Structure

D type

Each unit consists of 2-4 horizontal large capacitors laid on the frame, a multi-tap inductor is vertically installed above the sphere gap; 2-6 units are laid around the sphere gap in D pattern; inductors can be adjusted according to wave form and test object resistive during tests

Functions

It is mainly used to test the residual voltage and motion load of valve disc, arrestor and SPDs.

Advantages

Good appearance

As shown in the photo

Module design

The charging unit, resistors, capacitor frame, sphere gap are separate functional modules for easy reconfiguration and repair.

Flexible combination

Flexible combination of different units and within the units enables generating wave forms of different energy.

Easy modulation

Flexible combination of inductors and capacitors for easy modulation

Compact design

Spark gap cylinder, test bay, measuring components are assembled on a base frame; compact design and low inductance

Stable and reliable triggering

Durable graphite spark gaps; gap distance is adjusted by a drive motor; impulse firing available with stable triggering

Mobility

Universal wheels on each module for easy displacement?

Stable performance

Long-time operation at a voltage lower than 80% of rated voltage
