IDQ1 unterminated type M technical parameters

◇Basic Structure

IDQ1 series automatic power switch is mainly composed of power conversion actuator, circuit breaker and controller. This double power switch has automatic, manual, power supply indication, common closing indication, backup closing indication and other working states. The switch has the characteristics of small size, long life, low power consumption, light weight, stable operation and easy to use.

Installation and use method

Installation and wiring, the common power supply N bit access to the common power implementation circuit breaker QN, the backup power supply R should be connected to the backup power implementation circuit breaker QR when QN and QR for four-wire circuit breakers, wiring according to the wiring diagram - which QN and QR 1, 3, 5 for three A, B, C) into the terminal, 2, 4, 6 for the three-phase out of the terminal, 7 for the zero line (N) into the terminal, 8 for the zero line out of the terminal. If the choice of three-pole circuit breaker, the common power N zero line (NN) and the backup power R zero line (NR) together are connected to the three-pole special zero line terminal KG. See the wiring diagram for specific protection. Double power conversion switch automatic controller work power from the circuit breaker QN and QR inlet terminal A phase and zero line N, in the automatic power conversion switch installation, wiring process, do not forget to connect the original in the circuit breaker inlet end of the machine controller sampling signal line magnetic break or short circuit, etc. Otherwise, it can not work properly.

◇Use operation

When pushing the handle to rotate clockwise to the terminal, the common power supply executes circuit breaker N to close and the backup power supply executes circuit breaker QR to close, when pushing the handle to rotate counterclockwise to the terminal, the backup power supply executes circuit breaker OR to close and the common power supply executes circuit breaker N to close.

◇Intelligent controller function

IDQ1 intelligent double power conversion switch, the controller by the keyboard bit input and LCD) LCD display, can be commonly used power (N) and backup power (R) three-phase four-wire synchronous detection: phase failure, loss of voltage, power outages with detection functions, below 80% of the rated working voltage value is judged as a loss of voltage: backup power (R) failure alarm, the microcomputer to test the results to make processing, and then issue the corresponding instructions, The processing results can be displayed on the LCD, giving the user a good man-machine interface, the microcomputer detects abnormal data delayed into the double-phase state, after the delay (0-305) conversion to normal power supply.

◇Structure and function

The switch works in two states for users to choose: common power supply N) close, standby power supply N points, standby power supply R points switch has a small size, light weight, stable performance, easy to use and other characteristics.

◇Self-throwing self-recovery (R) grid

Factory initial default automatic, common power supply, when the power supply anomaly (any phase loss of voltage or phase failure), the controller ShCD on the NA, NB.NCRA, RB, RC will disappear accordingly. Commonly used power supply N abnormal, by delay 35 switch to the backup power supply R power supply, the delay time can be set to 0 ~ 305, factory set to 3s.

When the common power supply returns to normal, it will automatically switch from the backup power supply to the common power supply N. When the backup power supply R is abnormal, the controller will issue which alarm signal, the alarm can also be considered closed. the disappearance of the alarm word on the LCD indicates that the alarm system has been closed, there is no alarm function at this time. Press the minus key to display the alarm word, and at the same time will issue a sound, indicating that the alarm system has been opened.

Self-injection and self-restoration (F) grid

The controller detects the common power supply N and power generation power supply R. When the common power supply N is abnormal, the control system sends a power generation command to the generator set with normally open contacts to start the generator set, and when the voltage of the generator set reaches the normal working voltage value, the controller sends a command to put the power generation power into use to ensure the normal operation of the generator set.

When the generator voltage is lower than 75% of the rated value, the control system will automatically disconnect the load, into a double split pretence, when the grid voltage N back to normal, the intelligent system by the delay, then from the backup power supply R automatically return to the common power supply N, the generator set needs to be manually shut down
