Product Overview

IDQ3 automatic transfer switch (ATSE) is an automatic transfer switch that integrates switching and control, and truly realizes electromechanical integration, with voltage measurement, frequency detection, communication interface, electrical and mechanical interlocking, etc. It can realize automatic, electric remote and emergency manual control.

The operation is realized by the logic control board with various logical commands to manage the operation of the motor and gearbox, and the motor drives the switch to spring into action and release the acceleration mechanism to quickly connect and break the circuit or convert the circuit, and achieve safety isolation through the obvious visible state, which improves the electrical and mechanical performance.

IDQ3 switch is designed as a whole with metal enclosure, compact and sturdy, IDBQH2 switch, the control part is metal enclosure, the switch enclosure parts are made of glass fiber unsaturated polyester resin, which has strong dielectric properties, protection ability and reliable operation safety.

The switch is suitable for automatic changeover between the main power supply and the backup power supply of the power supply system or automatic changeover of two load devices and safety separation.

The switch is beautiful, novel, simple, small in size and full of functions, which is the choice for different occasions.

Model Meaning

Conformity to standards

IEC60947-1/GBT14048.1 "Low-voltage switchgear and controlgear Part 1 General Provisions

IEC60947-3/G814048.3 "Low-voltage switchgear and controlgear Part 3: Switches, disconnectors, isolating switches and fuse combinations electrical

IEC60947-6/GB14048.11 "Low-voltage switchgear and control equipment Part 6-1: Multifunctional electrical switchgear".

Product Use

IDQ3 series automatic transfer switch is mainly used for AC 50Hz, rated voltage 380V DC rated voltage 220V, rated current 16 to 3200A in power distribution or motor network, one main and one standby or mutual standby power switching system and load switching of utility and generator set. At the same time, it can be used for infrequent connection and disconnection of circuits and lines with limited separation.

The products are widely used in transmission and distribution systems and automation systems in important power supply places such as fire-fighting, banks and high-rise buildings where power failure is not allowed.

Performance and Features

◇Using double-row composite contacts, cross-pull mechanism, micro-motor pre-storage and micro-electronic control technology, basically zero flying arc (no extinguishing cover)

◇Reliable mechanical interlock and electrical interlock are adopted, and independent load disconnecting switch is used for the actuating element, which is safe and reliable.

◇Adopting over-zero technology, it can be set to zero forcibly in emergency (cutting off two power supplies at the same time) to meet the needs of fire-fighting linkage

◇The switching of load disconnecting switch is driven by a single motor, which is reliable, smooth, noiseless and with low impact.

◇The operator drive motor only passes current in the switching division of the load disconnecting switch, and there is no need to provide working current for steady-state operation, which is energy-saving.

◇The executive load isolation switch is equipped with mechanical interlocking device to ensure that the common and standby power supplies work reliably without interfering with each other

◇With obvious functions such as pre-determined position indication and padlock, it can reliably realize the isolation between power supply and load.

◇Good safety performance, high degree of automation, high reliability, service life over 8000 times

◇Electromechanical integration design, accurate, flexible and smooth switching, logic control technology, strong anti-dry resistance, and no interference outside

◇The main power supply is combined and the backup power supply is divided; the main power supply is divided and the backup power supply is combined: the main and backup power supplies are both disconnected for three kinds of stable work 1-O-m

◇Convenient installation, the control circuit is connected by plug-in terminals

◇Four kinds of operation functions: emergency manual operation, electric remote control operation, emergency disconnection operation in automatic control state, automatic control operation
