Automatic changeover Switch
QGLD Automatic Transfer Switch integrates switch and logic control,Thus it is not necessary to provide external controller.This truely electrome chanically intergrated automatic chang-over switch has the following functions such as voltage detection,frequency detection, communication interface, elecrical and mechanical interlocking etc., So, automatic control, electrical remote control and emergency manual control can be performed.
The operation is carried out though the logic control board,which gives various commands to control the motor and gearbox. the motor drives the accelerator which can take switch-spring power accumulating and instantaneous relaese,swiftly turns making and breaking the circuit or makes circuit switching. The visible operation status can help you to perform safe separation, increasing extremely the various electrical and mechanical performance.
the shell of QGLD switch is made of different materials: its control section is made of metal, but the switching section is made of glassfibre unsaturated polyester resin,having stronger dielectric property and protective capability as well as safe operation performance.
This kind of switch is suitable for the automatic change-over of the main power souce and the secondary power source of the power supply system or the automatic change-over and safe separation of the 2sets of load-equipment.
this kind of switch has a beautiful, novel and simple structure,a small volume but complete functions, being the best choice among congeneric of products.
QGLD series had been already passed the detection of EMC
