QGLD(HGLD) automtic change-over switch (ATSE) integrates switch and logic control.Thus it is not necessary to provide external controller .
   This truly electrome chanically intergrated automatic change-over switch has the follwing functions, such as voltage detection,frequency detection,communication inferface, electrical and mechanical interlocking etc.,So automatic control,electrical remote control and emergency manual control can be performed .
   The operation is carried out through the logic control control board ,which gives various commands to control the motor and gear-box.The motor drives the accelerator which can take seich-spring  power accumulating and instantaneous  releade ,swifty truns 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 switch QGLD(HGLD)1, QGLD(HGLD)2 is made of metal,being small and compact,While the shell of swich QGLD(HGLD) 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 oroperty and protective capa-bility as well as safe operation performance.
 The kind of switch is suitable for the automatic change-over of the main power source and the secondary power supply system or the automatic change-over and safe separation of the 2sets of load-equipment.
  This kind of switch has beautiful ,novel and simple structure,a small volume but complete functions,being the best choice among congeneric of prouducts .
  QGLD(HGLD)series had been already passed the detection of EMC.
