ZQ3-100-6300

Product overview

ZQ3 automatic transfer switch, which integrates switch and logic control, does not need external controller, and truly realizes electromechanical integration. It has the functions of voltage detection, frequency detection, communication interface, electro-pneumatic and mechanical interlock, and can realize automatic, electro-pneumatic remote and emergency manual control.

The operation is realized by the logic control board managing the operation and operation of the motor and gearbox with various logic commands. The motor drives the switch spring to store energy and instantly release the acceleration mechanism, which quickly turns on the breaking circuit or switches the circuit, realizes safe isolation through obvious visible state, and greatly improves the electrical and mechanical properties.

The overall design of ZQ3 switch is a metal shell, which is small and strong. The switch control part is a metal outer shell, and the switch outer shell parts are made of glass fiber unsaturated polyester resin, which has strong dielectric properties, protective ability and reliable operation safety.

The switch is suitable for automatic conversion between main power supply and standby power supply of power supply system or automatic conversion and safety isolation of two load devices, etc.

The switch is beautiful, novel, concise, small in size and full in function, which is an ideal choice for different occasions.

Scope of application

The ZQ8 automatic transfer switch is mainly used for AC 50Hz, rated voltage AC380V, rated DC voltage 220V, rated current from 100/K3200/K in the distribution or motor network, one main and one standby or each other’s standby power conversion system, and negative load conversion of commercial power and generator set. At the same time, it can be used to isolate circuits and lines that are not frequently switched on and off.

Products are widely used in power transmission and distribution systems and automation systems in important power supply places such as fire protection, hospitals, banks, high-rise buildings, etc.

Performance and characteristics

1. Adopt double-row compound contacts, horizontal pulling mechanism, micro-motor pre-energy storage and microelectronic control technology to basically realize zero arcing (without arc extinguishing cover).
2. Reliable mechanical interlocking and electrical interlocking are adopted, and independent load isolating switch is used as the actuator, which is safe and reliable to use.
3. Zero-position technology has been adopted, which can be forced to zero in emergency (two power supplies are cut off at the same time) to meet the needs of fire control linkage.
4. The load isolating switch is driven by a single motor, and the switch is reliable and smooth, with no noise and little impact.
5. The motor driven by the operator can only pass current at the moment when the load isolating switch is switched, so it is unnecessary to provide working current for steady-state operation, and the energy saving is remarkable.
6. The load isolating switch is equipped with mechanical interlocking device to ensure that the common and standby power supplies work reliably and do not interfere with each other.
7. It has obvious on-off position indication, padlock and other functions, and reliably realizes the isolation between power supply and load.
8. Good safety performance, high degree of automation, high reliability and service life of more than 8,000 times.
9. Electromechanical integration design, accurate, flexible and smooth switching, international advanced logic control technology, strong anti-interference ability and no external interference.
