YRQ1CB series automatic transfer switch is used for the two-circuit power system of AC 50/60Hz and rated voltage up to and including
690V. It is able to actuate the automatic transfer between the normal power and reserve power, requiring no manual operation. This
switch conforms to the clauses stipulated in the GB/T14048.11 Automatic transfer switching equipment. It is operating mechanism
has reliable electric and mechanical interlock to prevent the normal power and reserve power being switched on at the same time.
Working Principle:
The letters N, R, QN and QR respectively indicate the normal power, reserve power, normal power actuating breaker and reserve
power actuating breaker. Two breakers have the mechanical and interlock dual protections. The controller is made up of voltage
discrimination, phase-failure protection, and control four parts. When the normal power is normal, and, the switch works in the
automatic position, whether QR is in the "closing" or “opening” state, it always finishes the QR-off QN-on program first
therefore, it can guarantee the load is connected to the normal power. When the normal power has the trouble like the voltage
loss, under voltage or phase failure, after the specified time, the load will be transferred to the reserve power.
The controlling circuit breaker of switch may be the 3-pole or 4-pole molded-case circuit breaker, it can realize the automatic
and manual operation, meanwhile, it can actuate the dual power supplies of automatic and forcible load transfer. According to the
customer requirement, normal power indicator, reserve power indicator, normal power tripping indicator and reserve power tripping
indicator may be connected from the external terminal to the control panel.
