Overview of 1000V Photovoltaic Fuse Switch Disconnector 125A-250A Combined Fuse Holder Isolation Switch Unit

1000V Photovoltaic Fuse Switch Disconnector 125A-250A Combined Fuse Holder Isolation Switch Unit is critical switching equipment used in electrical systems of power plants and substations. Its primary function is to guarantee the safety of high-voltage electrical appliances and equipment during maintenance work and to isolate voltage. It cannot be used to cut off, input, or disconnect load current and short-circuit current. It can only be used for certain switch operations that do not generate strong arcs—usually used in conjunction with high-voltage circuit breakers to isolate the power supply during maintenance, providing safety protection for maintenance personnel and equipment. According to the installation location and the number of insulation columns, they can be divided into indoor type, outdoor type, single-column, double-column, and three-column types. The electrical system of power plants and substations is crucial for guaranteeing the safety of maintenance personnel and equipment.

Characteristics of 1000V Photovoltaic Fuse Switch Disconnector 125A-250A Combined Fuse Holder Isolation Switch Unit

“Safety guarantee during maintenance of high-voltage electrical appliances and devices: This is the primary function of high-voltage isolation switches, which can ensure the safety of equipment and operators during maintenance work.

Isolation voltage: It plays the role of isolating voltage and cannot be used to cut off or connect current, nor can it be used to break short-circuit current.

Nonarc extinguishing function: It cannot be used to cut off current; that is, it does not have an arc extinguishing function.

Multiple types: According to the installation location, it can be divided by indoor and outdoor types. According to the number of insulation pillars, they can be divided into single-column, double-column, and triple-column types. Each voltage level has optional equipment.”
