HGLK load isolation switch
First, HGLK load isolation switch use
HGL series isolation switch (hereinafter referred to as switch)，It is suitable for power distribution equipment of industrial enterprises with AC 50Hz, rated voltage 400V and agreed heating current up to 3200A，Used for infrequent switching and breaking current and electrical isolation (over 1000A only for electrical isolation)，It is widely used in power distribution systems and automation systems in construction, power, petrochemical and other industries。
HGL (T) transparent isolation switch, the ordinary shell is replaced by a transparent shell, which can directly observe the on-off state of each contact and the running state of the operating mechanism, and is equipped with a wiring cover at the inlet and outlet terminals。
HGL (C) side operation isolation switch, a side operation mechanism is added on the basis of the HGL front central operation isolation switch, which is suitable for the side operation of the on and off circuit and electrical isolation。
The HGL (Z) double-throw conversion isolation switch is composed of two HGL isolation switches stacked up and down or left and right, which is suitable for the switching of dual power supplies or the conversion and safety isolation of two load devices。
The switch is beautiful in appearance, novel and simple, simple in structure and easy to operate, in line with IEC60947-3 and GB/T14048.3标准！
Second, HGLK load isolation switch display
Three, model and meaning
Conventional models: HGLK-160/3,HGLK-250/3,HGLK-400/3,HGLK-630/3
Four, structural characteristics
● The switch has 3 poles and 4 poles (3 poles + can be switched off neutral poles)。
● The switch is mainly composed of base, large cover, small cover, contact system, operating mechanism, handle and other parts。The switch adopts the acceleration closing mechanism of spring energy storage and instantaneous release, and the contact structure of connecting and disconnecting parallel double breakpoints simultaneously, which greatly improves the electrical and mechanical properties of the switch。
● The switch adopts glass fiber reinforced unsaturated polyester molding material and manual operation handle, which has high dielectric properties, protection ability and reliable operation safety。
● The size cover of the transparent switch is made of new materials with high transparency, high strength and high temperature resistance, which can directly observe the on-off state of each contact and the running state of the operating mechanism, ensuring the safety and reliability of the switch operation。
● The front side of the switch is provided with a marking window to indicate the on-off state of the contact;The rear observation window can be provided as required to directly observe the on-off status of the contacts, ensuring the reliability and safety of the switch operation。
● The operation handle can be directly installed on the switch to operate (referred to as the cabinet operation), or can be operated outside the distribution cabinet door by lengthening the shaft (referred to as the cabinet operation), providing easy operation。
● It can provide normally open and normally closed auxiliary contacts and front and back wiring modes according to needs to meet various needs of users。
● When the breaking position is "0", two to three locks can be used to lock the handle to prevent misoperation。
● The transfer isolation switch has three indicating positions: "I" indicates that switch I is on, switch II is off;0 indicates that switch I and switch II are off, and switch I is off。
Five, main technical parameters
● Main technical parameters of HGL series isolation switch (see the following table)
● The main parameters of HGL (T) transparent isolation switch correspond to HGL。
● The main parameters of the isolation switch such as side operation, out-of-cabinet operation, out-of-cabinet operation, wiring behind the board, and direct observation of the contact window are all corresponding to HGL。
● The main parameters of the HGL (Z) double-throw conversion isolation switch correspond to HGL。
Six, shape and installation size
● Optional installation base plate
● Operating handle inside the cabinet
● The opening size of the handle and panel outside the cabinet
HGL-160~630 operates outside the cabinet
● HGL-100 is operated outside the cabinet
● HGL-800~3200 outside the cabinet type A operation
HGL-2000~3200/Z outside the cabinet type A operation
● HGL-800~3200 outside the cabinet type B operation
HGL (C), HGL-100~1600/Z outside the cabinet type B operation
Seven, the outline installation size
● HGL/K-160~1600 dimensions
● HGL/K-2000~3200 installation dimensions
Note: The * size of the tape is the size of the connecting copper
● HGL-160~1600/H (rear operation of cabinet) outline installation dimension
● HGL-160~1600/B (rear board wiring) outline installation dimensions
