Ⅷ Main structure and the working principle

TKQ3 series dual power automatic transfer switch is made of two molded case circuit breakers (MCCB), transporting structure electricity machinery with mechanical interlocks, intellectual controller etc, all the devices are installed on one panel. And the controller interior is intellectual

产品说明书

auto controlling circuit, made of MOTOROLA single chip micyoco (SCM) and advanced, reliable electronic component.

1. Working principle of auto controller

The auto controller tests the three phases voltage of normal and reserved power supply in the same time, when the numerical is 110% higher than the rated one, the controller views it as over-voltage, 60~85% lower than the rated one is under-voltage (the user can set the specific parameter freely). The internal circuit judges the test result of the timely phase for six voltages margin. When the result passes the relay, it drives the related relay give the open and close orders to the electricity machinery operating structure. And the above test result will be showed by some LEDs on the panel. There are four working ways (“automatic and manual”, “normal power supply”, reserved power supply”, “release <reclose>”), transfer delay time and the under-voltage numerical can be set through six push button switches. The switches are installed on the panel.

2. Test and control function of auto controller 2.1 self-input and self-recover auto controller

TKQ2 is used for the auto transforming between the normal power supply and reserved power supply. In usual time, the power was supplied by the normal power supply, and when it become abnormal (any single phase is over-voltage, under-voltage, interrupted phase), the reserved power supply will work after the appropriate delay; when the normal power supply refined, it will work once again automatically.

Make sure the reserved power supply is no damaged. When it has some abnormal situation, the related LED on the panel will turn yellow, and the internal buzzer will offer an alarming signal to tell the user to restore.

2.3 power grid generating auto controller

TKQ2 is used for the auto transforming between the normal power supply and reserved power supply. In usual time, the power was supplied by the normal power supply, and when it becomes abnormal (any single phase is over-voltage, under-voltage, interrupted phase), the intellectual controller orders to release the electricity by offering a controlling request as well as a unloading order (when the generator’s capacity is limited, user can unload the unimportant section). When the generating voltage is up to 85% of the rated one, the power of power grid will be cut automatically after some delay, and after some other delays, the generating power supply will work automatically. When the normal power supply recovers, it will work automatically
