HSQ6 series automatic transfer switch is made up of two parts: the switch controller and the switch body, The two are connected by a special cable HSQ6y is an integrated automatic switch electrical appliance, the conversion controller is connected with the switch body.On the one hand, the conversion controller monitors whether the common power supply and standby power supply are normal, and receives the external signal (such as remote control)On the other hand, according to the working mode set by the user to the converter controller, the switch body sends out the instruction to control the start and stop of the generator set.
HSQ6 series compared with other domestic and foreign manufacturers of similar products, has the following characteristics:
- The switch body structure is the building block type, the volume is small, is the same specification CB class ATSE volume 1/3-1/2.
- The main contact system for single pole double throw (three point) structure, its interlocking, will not cause the phenomenon of two power supply connected at the same time.
- Operating mechanism for single coil two-way operation, simple structure, fast conversion speed, less than 150ms
- Main contactor conversion capacity is big, can take 6Ie transformation.
- Each phase of the two power supply is detected, and the detection precision is high, and the small fluctuation of any phase or three-phase voltage is controlled by the switching controller
- The utility model has the advantages of convenient adjustment, over voltage threshold and under voltage threshold, which can be set by the user according to the power supply quality of the local power network,Conversion time, return delay and others parameters can also be set by the user as required, Parameter setting is convenient and quick
- Equipped with mechanical switch ontology fault alarm,When the switch body is unable to be converted due to a certain reason,the fault indicator light on the converter controller is light on and the power supply of the electric operating mechanism will be cut off at the same time In this way, on the one hand, the utility model can provide a small fault range for the workers, and on the other hand, the damage of the electric operating mechanism can be prevented.
- HSQ6y series automatic transfer switching equipment for the integrated structure, controller and switch body put together,the plate need not open holes, adopt the way of free disassembly Commonly used power aspirant line, under the standby power into the line,load under the line,conform to the user habits.
Normal working conditions and installation conditions:
The ambient air temperature is 5 ℃ ~ + 40 ℃.And the average value of 24 hours does not exceed +35℃
The elevation must not be above 2000m
Installation site of air relative humidity when the highest temperature is + 40 ℃ not more than 50%, at a lower temperature can have higher relative humidity, such as 20 ℃ at 90%.Due to temperature change occasionally produce condensation special measures should be taken
Installation site pollution level 3
Installation conditions: the switch body and the conversion controller installation conditions for vertical installation,can also be horizontal installing
According to the current level of the shell of the HSQ6 switch body, there are the following 3 shell bracket grades to choose from.

Note：
- ①Grid-power generation models, the conversion time and return time are consistent with the T2 setting. The start-up time of the generator is determined by T1 setting, and the setting range is 0 ~ 15s
- ②Only grid – power generation models have this feature
- ③HSQ6y-100, HSQ6y-200 display module can be installed separately (with voltage display).
- ④Can only choose automatic transfer and restoration or automatic transfer without restorationli>
