CHAPTER 1. ABOUT THE PRODUCT

1.1 Summarize

The High-Voltage Circuit Breakers dynamic characteristics testing

instrument is my company designed to meet the need of testing High-

Voltage Circuit Breakers . It takes the ARM7 unit for core to sample,

process and then output; the main characteristic is that its operated in

alt. It has many advantages such as intelligence, multi-function, accurate

data, strong anti-jamming, easy operation, small size, beautiful

appearance, etc; It can test the Circuit Breakers as follows: indoors or

outdoors Circuit Breakers with less oil or more oil, vacuum Circuit

Breakers, SF6 Circuit Breakers and so on.

1.23 How to connection

Require: fix the senor to the A1.

1when using the internal power supply, closing control connects to

picture 36 using our lines; opening control connects to in picture

36; Common connects to -KM in picture 36; the fuse in picture 36

must be removed.

1.24 Fit sensor in oil Circuit Breakers

open the cover of the explosion chamber, insert the transmission pole into

the explosion chamber, and screw the inside end of the transmission pole

tightly to the screw of the moving contact, the other end of the pole connects to

the sample ruler.

The ruler should glide in the runner easily, and the base of the ruler must be fixed

to the explosion chamber.

Requirements: connect the contact to the A1 on the front-panel, the signal

lines plug of the sampler connects to the Sample Input interface, when fix the

sample pole ,the sample ruler should be kept clean and straight. when theres

pollute like oil or dust in the sample ruler, the ruler should be cleaned by gasoline

or alcohol., or the measured results may be discrete.

How to connect: all the moving contacts of the switches connects to the

ground hole in the front-panel of the tester, the ground hole then connects to the

earth ground reliably; the static contacts to the A,B,C hole correspondingly.(see

Picture 38)

Let the switch be at a open state, fix the senor to fixed shelf in the bottom

of the switchs, make the probe just touch the moving contact by adjusting the

spring, use the line to connect the probe and the External Trigger hole in the

front-panel, how to connect the remainder lines is just like the method for oil

switch.(see picture 39)

1.26 Fit sensor in SF6 Circuit Breakers

Remove the glass window of the lift-pole room, fix the fixing board with the

infrared-induction head into the screw hole in the room, fix the sample ruler to

the corresponding position , adjust the fixing parts to make the ruler to slide in the

runner up and down, how to connect the lines is just like the methods for other

switches.(as picture 40)
