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.

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.
