Product Overview

TN1QG dual-power automatic transfer switch (ATSE) is a new type of automatic transfer switch that integrates switch and logic control and truly realizes mechatronics, which is suitable for power distribution equipment of industrial and mining enterprises with rated insulation voltage to 1000V, rated frequency of 50Hz, rated voltage of 400V, and agreed heating current of 3200A; It is used as the automatic conversion of the main power supply and the standby power supply system or the automatic conversion and safety isolation of two load equipment; It is widely used in hospitals, shopping malls, banks, high-rise buildings, coal mines, telecommunications, iron mines, highways, airports, industrial assembly lines and military facilities and other important occasions that do not allow power outages.

The switch is controlled by the circuit board to issue various logic commands to manage the motor, and the motor is rotated by the gearbox to drive the spring energy storage and instantaneous release of the operating mechanism, so as to quickly connect and break the circuit or carry out circuit conversion, and achieve safety isolation through the obvious visible state.

The switch can realize fully automatic, forced "0", remote control, emergency manual and other operations; And it has the functions of phase loss detection protection, electrical and mechanical interlock, with generator (oil engine) and so on. The switch is beautiful in shape, novel and concise, small in size and full in function, and is the choice of similar products.

Model Meaning

Type I: Fully automatic

Type II: Fully automatic, forced "0", remote control

Type III: Phase Loss Detection Protection, Fully Automatic, Force "0", Remote Control, With Generator

Description of the Switch Structure

Electrical key lock: the control switch controls the power supply of the line internally, and when the electrical lock is opened, the switch can realize fully automatic, remote control, and forced "0" operation; When electrically locked, the switch can be operated manually.

Joystick: When using the joystick to operate manually, the electrical lock must be closed first.

Mechanical padlock: a special padlock mechanism for maintenance, the switch is hit to the "0" gear during maintenance, and then the padlock on the padlock mechanism is pulled up, which can prevent any accidents (pull up the padlock to cut off the inside of the switch

The control power switch cannot be automatic, and it cannot be manual).

Indicates the three states (I, 0, II) position of the switch, "I" indicates that switch I is on, and "II" means that switch II is on,

"0" indicates that switch I and switch II are both disconnected. The external signal of the terminal block is detailed in the manual.

1. Fully automatic: that is, self-throwing and self-resuming, when the commonly used power supply is powered off (or out of phase), the switch will automatically switch to the standby power supply: and when the common power supply returns to normal, the switch will automatically return to the common power supply.

2. Forced "0": In case of emergency or equipment maintenance, start the forced "0" self-locking button, and the switch will automatically switch to "0" gear to cut off the dual power supply.

3. Remote control (remote control): that is, remote operation control, start the "I" file button, then the commonly used power supply is put into work; Activate the "II" button and the backup power is put into operation.

4. With generator (oil engine): when the mains power supply is powered off (or out of phase), the signal of the oil engine will be sent to start, so that the oil engine will start automatically, and after the power generation is normal, the switch will be automatically converted to the power generation power supply, and when the power supply of the main power supply is restored to normal, the switch will automatically return to the power supply, and at the same time send out the signal that the oil engine is turned off, so that the oil engine will be automatically closed.

5. Missing phase detection and protection: detect and protect the power failure of any phase of the standing (standby) power supply.

The switch conforms to: GB/T14048.11:

Rated Operating Voltage (Ue): AC400V;

Rated Turn-On Capability (ARms): 10Ie;

Rated Breaking Capacity (ARms): 8Ie;
