Main uses
HYCQ5 series double power automatic transfer switch is used in AC 50Hz, rated voltagebelow 690V two power supply system. It can make a automatic transfer between normalpower and reserve power but without manual operation. This switch accords with thefollowing terms of national GB/T14048. 11<
>standards: ◆ Operating mechanism should have reliable electrical and mechanical interlocking, in order to prevent concurrent access to the
normal power and reserve power.
◆ When the voltage of detected any phase and all the phases of the normal power interrupt in ascheduled time. HYCQ5 will swithch
to connect the load from normal power to reserve power, and when the normal power goes back to normal, it will automatically
connect the load to the normal power(with phase failure protection function).

◆ The main structures of switch as drawing 2 showing
Drawing 2 N is the normal power, R is the reserve power. Qn is circuit breaker for the normal power, Qr is circuit breaker for the reserve power. Betwwen of them, there is Mechanical in terlock ing double protection. The controller consist of four parts: voltage identiry, phase failure protection, delay and control.Voltage identify and phase failure protection connect the input terminals of the normal power. When the normal power is normal, The switch work in automatic gearshift, no matter what state the Qr are. Qr is off and Qn is on to insure the normal power switching on the load. When the normal power has problem (such as loss of voltage, undervoltage, phase failure), in a certain period of time,The switch will make the load connect the reserve power from the normal power. When the normal power return to normal, then the switch will make the load connect the normal power.
The molded case circuit breaker of the HYCQ5 switch can be 3 poles or 4 poles, can be automatic or manual operation and can realize the load changing-over automatically or compulsively. According to the demand of customers, the normal power indication, the reserve power indication, the normal power trippingindication and teh reserve power tripping indication all connect from external terminals which lead to control panel. For self put in without self restoring, the reset button can also be eduction from external terminal.
This series automatic transfer switch plots simple, no need to draw up secondary connection diagram, so convenience project design greatly. It is recommended to use the design of drawing 3 annotation diagram.

This dual-power transfer switch has "Manual" function for manual switching between the normal power and reserve power, and "Automatic" function for automatic switching between the two power supplies, as well as word display such as "Automatic", "Manual", "Normal power undervoltage", "Normal power overvoltage", "Normal power on", "Normal power tripping", Reserve power undervoltage", "Reserve power overvoltage", "Reserve power on", "Reserve power tripping".
◆ When the normal and reserve power supplies supply power simultaneously, if the normal power voltage is higher than 115% or
lower than 85% of the rated voltage, the dual-power switching system will judge it as fault and transfer to the reserve power supply
automatically, and display "Normal power overvoltage" or "Normal power undervoltage".

◆ Mode of auto-switch-in auto-restoring is suitable for power grid-power grid. The intelligent automatic controller carries out
automatic switching between the two circuits of power supply(i.e. normal and reserve power supplies), power supplied by the
normal power supply under normal condition, and transfer to the reserve power supply automatically after the preset time delay
(adjustable) once the normal power is failed or is abnormal (any one group of voltage occurs overvoltage,undervoltage, no-voltage
or open-phase), and return to the normal power supply automatically after the preset time delay (adjustable) when the normal
power supply recovers.◆ Mode of auto-switch-in without auto-restoring is suitable for power grid-power grid. The automatic controller with mode of
auto-switch-in without auto-restoring carries out automatic switching between the two circuits of power supply (i.e. normal and
reserve power supplies). It transfers to the other normally operated power supply after the preset time delay when one power
supply is abnormal (any one group of voltage occurs overvoltage, undervoltage or open-phase), and will not restore automatically
when the abnormal one recovers.◆Power grid-generator, when it is used in the power gridgenerating system, the automatic controller catrries out switching between
the power grid and generator. When teh power grid voltage is lower than 85% of the rated voltage, the controller sends out power
generation command (output by one group of NO NC contacts). when teh generating voltage reaches 85% of the rated voltage. it
cuts off the load circuit from the power grid first, then put through the generating power supply after time delay. When the power grid
recovers normal (reaches 85% above of the rated voltage), the controller will cut off the loads from the generating power supply and
transfer to the power grid automatically through intelligent logical judgment.Operating state table
Breakdown maintenance
1. No response after startup, the electric operating mechanism not work by pressing the command key, please check the
connection condition of power lines of circuit breaker as well as the special cables.
2. After power on, each phase voltage is normal, but the panel displays under voltage, please check to see whether the power supply
of circuit breaker has been well connected, whether there is open-phase phenomenon; check whenther the fuse wire on device body
is burnt out for too heavy current of electric operating mechanism, if yes, just change it.
3. If the fuse tubes are burnt out often, please check whether the electric operating mechanism is blocked, and adjust it properly.Notices
1. Please carry out periodic inspection and maintenance to the intelligent system according to the requirements of circuit breaker and
electric operating mechanism. The intelligent controller is maintenance free under normal operating conditions.
2. The intelligent system should be protected from moisture or dust for long term service, and should be well debugged according to
the abovementioned content before putting into operation.อ้างอิงผลงานลูกค้า
