HD4断路器利用六氟化硫（SF6）气体作为灭弧和绝缘介质，六氟化硫气体的热膨胀性、负电性以及快速的复合作用使其成为灭弧的理想介质。
HD4断路器是基于热膨胀和压气助吹相结合的灭弧原理，该技术早已在高压开关领域中广泛成熟的应用。其具有非常平滑的开断特性，在开断电流时不会出现截流现象，因此不会产生操作过电压。优良的特性确保了HD4断路器具有很长的电气寿命，并且避免对运行中的负载设备造成冲击。
sequence control and batch intermittent control functions.
The internal communication of
the process control station (between the controller and various intelligent devices
such as I/0 or field instruments) adopts the international standard field controller.
Wire. The field controller supports various field buses such as Profibus. Profibus is
the most widely used open field bus in the world.
Line international standard, divided
into FMS, DP and PA three levels, DP communication rate can be as high as 12Mb. The CAN
(DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data
security. The system of course also supports Modbus. The communication with the
intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA
and FF bus).
The system communication between the operation management level and the
process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3
standard),
Users can choose the communication transmission medium (ordinary cable or 
optical fiber) and network topology according to the actual situation of the
application.
The popular PC and MS_ Windows 2000 have been widely used in various fields
all over the world, becoming the de facto standard computer platform.
tower. The
operating station 0S, the engineering station ES and the data gateway GS of the
Industrial” system use this platform to ensure the system’s
Versatility, openness and
ease of use, and bring great convenience to future technical upgrades and maintenance.
System engineering is very convenient. The configuration language is based on the
IE061131 3 industry standard, providing function block diagram (FBD), ladder diagram
(LD), instruction list (IL), sequential function chart (SFC), structured text (ST) and
other graphical configuration methods. The system contains about 220 functions

library for energy blocks and a basic library with more than 200 graphic symbols and an
extended library with a large number of 3D symbols.
The system uses the same set of
configuration tool software to complete the configuration and debugging of process
level, operation level and even fieldbus instruments, and uses the same

database.
The scale of the system is highly scalable, and a single-system supports 1 to
a maximum of 100 control stations and 100 operating stations. each control

can support several thousand I/0 points at most, and the scale of the whole system can
be expanded. The hardware of the system control station is encapsulated in an all-metal
shell, which can withstand the most
