FEEO research and development FDH photovoltaic dc isolator is mainly used solar power distribution system, namely pv junction box, etc. direct current electrical equipment. Rated voltage 1200 VDC, rated current 63 A,science of arcing design solar photovoltaic power generation system reliable operation.
isolation switch Parameters:
FDH series disconnector (disconnector) means that when in the
sub-position, there is an insulation distance that meets the
specified requirements and an obvious disconnection mark between
the contacts; when in the closed position, it can carry the current
under normal loop conditions and abnormal conditions within the
specified time (Such as a short circuit) under the current
switching device. (IEV441-14-05)
What we call isolating switches (commonly known as "knife
switches") generally refers to high-voltage isolating switches,
that is, isolating switches with a rated voltage of 1kv and above,
usually referred to as isolating switches, which are the most used
high-voltage switch appliances. Electrical appliances have a
relatively simple working principle and structure, but due to their
large usage and high reliability requirements, they have a greater
impact on the design, establishment and safe operation of
substations and power plants. The main feature of the isolating
switch is that it has no arc extinguishing ability and can only
open and close the circuit when there is no load current. Isolation
switches are used at various levels of voltage to change the
circuit connection or isolate the circuit or equipment from the
power supply. It has no current cut-off capability and can only be
operated after disconnecting the circuit with other equipment.
Generally, it is equipped with an interlock device to prevent the
switch from being operated incorrectly when the switch is under
load. Sometimes a pin is needed to prevent the switch from being
disconnected under the action of a large fault magnetic force.
