1, principle of work
When used in normal power function keys, automatic backup breaker
points, commonly used to protect circuit breaker, the electricity
load. When used in A three-phase power A voltage when the interrupt
or full load from common ATS, switching power to standby power
(when standby power have normal voltage), and used in the
restoration of power to normal, and will spare power conversion to
common power. 2, operation and maintenance
Whether common power and standby power, voltage or using manual
operation mode. Manual operation manual, should be placed manual
button - position, when push lever clockwise turn to the terminal,
standby power execution Qr circuit breaker, common power execution
break-brake Qn feeder breakers, When push handle counterclockwise
to terminal, standby power feeder breakers, common Qr executive
power execution breaker Qn break-brake, The panel power
automatically control box work, if the power bright lights,
automatic control box, cannot work power faulty switches. To repair
manual, after the normal position - automatic button, if used in
automatic switching power supply is normal, move to commonly used
in power supply, power indicator, If common power supply, switching
power supply will turn to spare, panel standby power indicator.
Switch has two 1A fuse and a terminals, fuse as automatic
controller short-circuit protection. Terminals for instructions
lights up to control box, which provide active power panel for ac
voltage, current 150mA is 220V, including specific operation may
refer to the instruction with random circuit diagram. |
1, CB class product structure and characteristics
CB class series intelligent automatic switching power supply is
double by two or three of the four extremely extremely molded case
circuit breaker and accessories (auxiliary, the alarm contacts),
mechanical interlocking transmission mechanism, intelligent
controller, etc. Two kinds of structure is divided into collector.
Integral is controller and actuators with in a base, Fission is
installed in the cabinet put oneself in another''s position
controller on the panel, actuators in base by users in the cabinet
put oneself in another''s position, install controller and
actuators with about 2m long cable connection. Its features are:
between two breakers with reliable mechanical and electrical
interlock protect interlock, the complete elimination of the two
feeder breakers and possibilitie |
