The switching between the common power supply and the standby power supply is completed by automatic or manual operation. The CDQ3 type change-over switch is mainly used in hospitals, shops, banks, metallurgy, high-rise buildings, military facilities and other important occasions where power failure is not allowed. Delixi CDQ3-100/225/400/630 series introduction CDQ3 series dual power automatic transfer switch apparatus is a new generation of automatic transfer switch developed by our company using microcomputer control technology. The switch uses the Multi9 series and Compact series circuit breakers or load switches of Delixi Electric Company as the actuating elements, and is equipped with a new type of electromechanical integrated control mechanism with electromechanical double interlock, which is especially suitable for important power supply places where power failure is not allowed. In order to meet the needs of the site, the automatic transfer switch can realize three different working modes: automatic switching and automatic recovery, automatic switching and non automatic recovery, and mutual standby. 1.1 Main features of Delixi CDQ3 product: three optional working modes, automatic switching and automatic recovery working mode, are mutually standby working mode, automatic switching and non automatic recovery working mode, three stable working positions, common power supply is closed, standby power supply is divided into common power supply, standby power supply is divided into common power supply, and standby power supply is divided into small size, simple structure, and beautiful appearance, With 1A-630A specification, easy operation and long service life, 2-pole, 3-pole and 4-pole switches can be provided. The switch switching drive is driven by a single chip microcomputer, with simple structure, reliable and stable switching, no noise, and small impact. The switch is equipped with the electrical interlock protection of the agricultural production system to ensure that the automatic transfer switch works reliably and does not interfere with each other. The switch can automatically switch with load. In case of emergency, the handle can be used to carry out manual switching. Compared with the similar products of other companies, the characteristic controller protects the fuse breaking capacity of 50KV, which improves the power distribution safety. Interlock is added between manual and automatic operation modes to ensure automatic operation failure under manual mode. The handle of the actuating circuit breaker is broken. In case of contact adhesion or load fault (overload, short circuit), the automatic transfer switch does not switch, which truly realizes electromechanical interlocking. The driving mechanism of MCB type automatic transfer switch was changed from fork type to concave type, which solved the problems such as the fracture of MCB lengthening handle and the unsynchronized closing of MCB. It provides wrong connection protection. When the user connects the working power supply to AC380V by mistake, it can start the emergency signal through sound and light, which improves the reliability of the equipment. 2.1 Delixi series conventional characteristics ■ Comply with the standard IEC60947-6-1:1998 (version 1.2) Low voltage switchgear and control equipment Part VI Automatic transfer switchgear GB14048.11-2002 Low voltage switchgear and control equipment Automatic transfer switchgear ■ Protection grade Ip20 ■ Application category AC-33B (CB product)/AC-23B（ PC Class A product) ■ Environmental conditions for use Normal working conditions: ambient temperature of the medium around the installation site is - 20~60 ℃, without dust and conductive dust, corrosive, flammable and explosive gases. No rain and snow erosion. Avoid direct sunlight and have good ventilation and heat dissipation. The magnetic field intensity at the installation site shall not be greater than 5 times of the geomagnetic field. It can withstand the influence of humid air. Metal, insulating gas and conductive dust. It can withstand the influence of salt mist, oil mist and humid air. In places free from rain and snow, the altitude is ≤ 2000m, and the larger inclination is 22.5 °, installation level III. 2.2 Notes on the use of Delixi CDQ3 series automatic transfer switch 1. If the working voltage is the same as the power supply voltage, the "common" and "standby" power supplies can supply power directly. If different, BC type or equivalent isolation must be used transformer 。 2. In the handle operation mode, the control appliance of the electrical operating mechanism is open circuit, and the automatic control is invalid. 3 The common power supply works under normal conditions of the two power supplies. If the common power supply fails, it will automatically switch to the standby power supply (the conversion delay is adjustable): when the normal power supply returns to normal, it will automatically return to the common power supply (the return delay is adjustable). 4 The common power supply works under normal conditions of the two power supplies. If the common power supply fails, it will automatically switch to the standby power supply, and the controller will stop the conversion, The switch will not return even if the common power supply returns to normal. Press the reset key, and the controller returns to normal. 5 When the two power supplies are powered on (or reset) under normal conditions, the common power supply party has priority. When the working power supply fails during operation, it will automatically switch to another power supply (the transfer delay of type B switch can be adjusted). The two power supplies are equal priority and standby power supplies for each other. 2.3 User wiring ■ Wiring ■ It is recommended that when the switch is installed in the box, it should be fixed by tapping or connecting bolts on the mounting plate to facilitate maintenance. ■ The switch is equipped with common power UN and standby power UR indication, circuit breaker closing indication and circuit breaker tripping indication. At the same time, it also provides these indication signals to avoid external output terminals (active). Users can determine external indicator lights according to their needs. For specific user wiring, please refer to the corresponding product wiring diagram in the appendix. ■ For the switch with type B controller, a group of generator start signal terminals (passive) are provided for the user, and the user can connect them to the generator start circuit as required. The provided fire terminal can accept the control signal of the fire center, turn the switch to position 0 (double opening), and cut off the non priority energy load. Operating instruction 1. When power is cut off for some reason and power supply cannot be recovered in a short time, the standby power supply must be enabled. Steps: ① Cut off all circuit breakers of the mains power supply (including all circuit breakers of the control cabinet in the distribution room, and the mains power breaker of the dual power supply switching box), pull off the dual switching anti reverse switch to the side of the self-contained power supply, and keep the self-contained power supply circuit breaker in the dual power supply switching box disconnected. ② Start the standby power supply (diesel generator set), and when the standby group operates normally, close the air switch of the generator in sequence and all the circuit breakers in the self-contained power supply control cabinet. ③ Close each standby power circuit breaker in the power switching box one by one to supply power to each load. ④ During the operation of the standby power supply, the operator on duty shall not leave the generator set, and shall timely adjust the voltage, plant frequency, etc. according to the change of load, and deal with any abnormality found in a timely manner. 2. When the mains power supply is restored, the power conversion shall be done in time, the standby power supply shall be cut off, and the mains power supply shall be restored. Steps: ① Disconnect the circuit breakers of the self provided power supply one by one in the sequence: the self provided power circuit breaker of the dual power supply switching box → the circuit breakers of the self provided power supply distribution cabinet → the main switch of the generator → turn the dual switch to the mains power supply side. ② Shut down according to the diesel engine shutdown procedure. ③ In order, close each circuit breaker one by one from the main mains power supply switch to each branch switch, and place the dual power supply switching box in the closed position from the mains power supply circuit breaker.
