SmartGen SGQ_ATS Automatic Transfer Switch

SUMMARY

SGQ Automatic Transfer Switch (ATS) is used under conditions of AC660V 50/60Hz or DC250V It is two-stage PC class type with an electromagnetism drive structure, which can make fast load transfer (transfer time ≤80ms) of two power circuits. It can be widely used for national one-class load, for example: high buildings, post, telecommunications, coal mines, ships, industrial assembly lines, health care, military facilities etc. The two power circuits can be grid, auto start genset, storage battery etc.

STRUCTURE AND CHARACTERISTICS

SGQ Automatic Transfer Switch (ATS) adopts an electromagnetic coil drive, electrical and mechanical interlocking structure, main loop structure of two static contacts and one dynamic contact. Dynamic contact applies V type, which ensures two power circuits shall not be short circuit. N-type and T type apply double coils; M-type applies single coil. Coils are only energized at the time of transfer and this extends the usage life of switch to a great degree. Coil control power can be supplied by master/slave AC or DC power and it is not needed to add another control power. Switch itself has mechanical or electrical close indication, and at the same time it provides volts-free auxiliary contact.

APPEARANCE AND CLASSIFICATION

ILLUSTRATION
SGQ ATS can be classified into 3 types by appearance: N type, T type, M type. Each type has 3P and 4P, and N type still has 2P.

The rated current series are: 63A, 125A, 160A, 200A, 250A, 400A, 630A, 800A, 1000A and 1250A. Switch appearances are as below.

INSTALLATION AND DEBUGGING

All operations about ATS installation and debugging shall be conducted by professionals or persons knowing the switch device and protection and precaution measures must be considered during the operation. Wiring connection of main loop must make sure leading wire is not taking any pressure or force. Before installation and debugging please check firstly whether switch is damaged or whether there is harmful environment effect on it. At the same time please check whether there is loose wire resulting from transportation; clear the smudge, especially the smudge on the surface of insulating parts. The smudge probably is caused by the packing materials in the transportation process or in the storage process. Please make sure the phase sequences are in accordance at connecting the first circuit; please observe the wiring connection diagram of user manual strictly at connecting the second circuit and pay attention to control power voltage class at the same time. Ground must be well connected on switch installation. Considering personal safety and switch changeover rapidity, debugging handle can only be used for debugging and users are prohibited to operate on-load with debugging handle. First use the handle to operate switch, and if nothing unusual occurs, then operate button manually. If nothing unusual happens, then normal running can start.
