Samples and Restrictions:
Various plugs and sockets, appliance couplers, switches and other
similar electrical accessories.
Application:
Used to provide adjustable load voltage, current and power factor
during mechanical-electrical contact system test. it is suitable
for breaking capacity and normal operation endurance test of
switches, plugs and socket-outlets for household and similar fixed
electrical installations, and electrical stress test for luminaries
and other similar tests. This series of resistive, inductive,
capacitive load cabinets should work with Sinuo's plug, socket and
switch endurance test equipment.
Test Principle:
The output voltage, output current and power factor can be adjusted
through the circuit combination.
Structure:
The load cabinet uses an integral steel structure frame and a
Toyota white seal plate. The control panel is in the upper part of
the equipment, there are external power supply switch, ammeter,
voltmeter and power meter, power display instrument, load power
supply switch, status indicators, start and stop buttons,
capacitance switch, load type switch and alarm on the control
panel. The voltage, current and power factor regulators are on the
lower part of the equipment. Each load station has a three-in-one
function of resistive, inductive and capacitive (fluorescent) load,
which can be switched by a transfer switch. The interior of the
load cabinet is cooled by strong wind convection. There are
terminals at the bottom of the back of the load cabinet, which can
be connected to the switch plug socket-out normal operation
endurance test equipment through the cables to output current,
voltage and power during the breaking capacity testing.
Use Environment:
Power supply: three-phase four-wire AC380/50Hz, 10KVA/station or
meet client's local power supply requirements
Use place: atmospheric pressure 80 ~ 106kpa; ambient temperature 5
~ 40 ° C; relative humidity (20 ~ 80) % RH; no vigorous shaking, no
vibration, no electromagnetic interference, no dust, no explosive
and no corrosive gas, with good heat dissipation
