Electrical Test Set Circuit Breaker Analyzer Mechanical
Characteristics Tester
I.Introduction
Circuit Breaker Analyzer is used for testing, analyzing and
assessing power system circuit breakers, mechanical characteristics
of load switches and isolated switches and other AC high voltage
switches, contact resistance, Arcing contacts and vibration
characteristics etc. The functions of Circuit Breaker Analyzer
cover all testing items of high voltage circuit breaks.
Comparing with the traditional circuit breaker tester, this Circuit
Breaker Analyzer has the following unique advantages:
1) The integrated vibration test function of Circuit Breaker test
set provides a new means of detection circuit breaker mechanical
characteristics for users, compared to traditional time measurement
and speed measurement, the vibration fingerprint detection is
easier and more efficient.
2) The vibration fingerprint test results contain richer
information of circuit breaker operation, for potential risk of
failure or faulty breakers, it can locate the fault position
quickly.
3) The vibration tests do not need to change the original line
connection, so the users can complete the charged detection of
mechanical characteristics of circuit breaker.
4) Arcing contact analysis module allows users to automatically
assess the degree of loss of inside Arc suppression contact of
circuit breaker without disassembly.
5) Users can use Circuit Breaker Analyzer to complete the contact
resistance tests, do not need to buy contact resistance tester
separately.
1) Measurement of closing time, opening time, time spread between
poles, time spread between units of one pole, bounces etc.
2) Measurement of closing speed, opening speed and average speed.
3) Measurement of clearance between open contacts, over travel,
overshoot travel and total travel.
4) Measurement of closing coil current time curve, opening coil
current time curve and the maximum coil current
5) Test travel time curve, speed time curve and acceleration time
curve
6) Measurement of pre-insertion resistance value and pre-insertion
ion time.
7) Test contact resistance
8) Measurement of dynamic resistance time curve and length for
arcing contacts
9) Vibration test, including vibration fingerprint curve
acquisition, management, and vibration fingerprint curve automatic
matching.
10) CO-t1-CO,O-t-CO-t1-CO,CO rated operating sequence verification
test.
11) Drawing Envelopes for reference travel curve and compare travel
curve with envelopes
12) Mechanical travel curve automatic compare with saved travel
curve
13) Measurement of CO time (close-open time) and OC time
(Opening-Closing time)
14) Graphite contact closing time, opening time, dynamic resistance
curve measurement
15) Zoom, editors, statistics and analysis for measurement curves.
16)12.1-inch touch screen for control and data input
17) Built-in micro printer for test result printout.
18) Generate WORD format test report automatically (all reports and
data can be exported through Flash disk).
