Purpose
DL-228 high-voltage switching characteristics tester is the latest
development of the sixth generation of products. The test system
consists of DL-228 high-voltage switching characteristics
tester;test the auxiliary power supply circuit box" of two parts.
DL-228 high-voltage switch dynamic characteristics tester and
fifth-generation switching characteristics tester compared with an
increase of stored energy circuit breaker, breaker circuit
resistance test, the circuit breaker auxiliary contact tests, the
circuit breaker closing resistor value and invest time in testing,
Siemens Operating characteristics of graphite contact switch test
function. While increasing the variety of guns by: grating rotary
encoders, slide resistance displacement sensor, linear acceleration
sensor.
Function
1) Equipped with industrial grade embedded operating system, 2G
storage capacity, and stability is much higher than commercial
systems, effective way to eliminate the virus infection and system
crashes, boot time is less than 10 seconds, far WINDOWS quickly.
Support the plug-in keyboard, mouse, U disk and Ethernet
connections.
2) With historical data management, query, compare, list, report
printing. Two USB ports and an Ethernet interface supports data
import and export.
3) Using wizard mode operation, the two Enter the basic tests can
be completed, user-control test to use.
4)Integrated operating power; graphite, closing resistors in power
supply, with no external power supply box.
5) A record with a sound and graphical curve analysis,
corresponding to the time coordinates shows the fracture state
waveform, O(C) coil current waveform, travel - Time (S-t) curves,
graphics can be global or local zoom, and simultaneous display
corresponding values in favor of the switch mechanism to determine
the exact performance; with angular rate sensor (one), acceleration
sensors, slide resistance sensor (three-way), can cover almost all
types of switching speed and travel testing;
6) Reclosing comprehensive test function, so that a variety of
tests can be arbitrary reclosing;
7) The design of loop resistance, resistance testing closing
function of a machine.
8) Perfect to meet the EMC design of the instrument than in the
500kV substation and reliable use, control line wiring
short-circuit protection and arc-off than the export capacity 3KW
guarantee exceptional circumstances, the user equipment and
personnel safety.
9) Support the switch operating mechanism of the low voltage test,
select pulse or continuous approximation of the impact of the test
voltage approaching the test in two ways, set the approximation
step.
10) Can be configured automatically after closing the switch energy
storage, energy storage time were recorded. Also supports an
external power supply or energy storage devices directly to the
switch DC power supply energy storage.
11) Applies to all domestic and SF6, vacuum, low oil pressure
switch and the movement of mechanical properties of voltage
measurement.
12) Test channel:
a. 12-simultaneous measurement of fracture (independent) inherent
points, closing
time
b.6 Aux node test, calculate the time jitter and jitter times,
reflecting the secondary node of the contact performance.
c.4 Road test the speed and stroke (three analog sensors, digital
sensors all theway)d.6 Road graphite calculated fracture data
acquisition
e.6 Road closing resistance test;
f.6 analog sampling channels (including the sensor channel), can be
configured to
calculate a variety of external data acquisition, such as: data
acquisition loop
resistance calculation, calculation of the external high-current
sensor acquisition.
13) Can test different switch configuration parameters to manage
and reduce the input parameters of each test.
14) Perfect short-circuit proof function. Accidental short circuit,
open and close the line of control will not have any security
equipment damage ring.
15) A data sampling results, you can set different parameters of
the rules for data analysis.
