Product Description

Scope of application

HG2B series strip fuse disconnector (hereinafter referred to as switch) is a high-performance electrical equipment, specially designed for industrial power distribution systems with AC 50Hz, rated voltage up to 660V, and agreed thermal current up to 630A. The switch can not only operate safely under load, but also has many innovative technologies, and pioneered the perfect integration design of current transformer and strip switch. This design makes the equipment more efficient and convenient during use.
The structural design of the HG2B series switch takes into account the actual needs of users. It has the convenience of swapping the upper and lower incoming and outgoing lines. Users can flexibly adjust the wiring method according to the actual installation environment. The switch also supports the single-phase independent disconnection function, which can safely cut off the single-phase circuit when necessary to ensure the safe operation of the equipment. At the same time, it can also achieve three-phase simultaneous disconnection, which is suitable for a variety of complex power system requirements.
Due to its superior performance and flexible application characteristics, HG2B series strip fuse disconnectors are widely used in complete sets of products and imported box-type substations, and have become an indispensable and important part of modern power distribution systems. Whether in industrial production, commercial buildings or other places with high power demand, HG2B series switches can provide reliable power protection to ensure the safe and stable operation of equipment.
The switch is novel and beautiful, and meets the standards of IEC60947-3 and GB14048.3.

Structural features

1
The switch is mainly composed of the base, the handle, the arc extinguishing cover and other parts. The three groups of static contacts are directly installed on the base. The fuse is installed in the handle and is directly used as the moving contact blade. The handle can be opened along the fulcrum on the base in a fan-shaped rotation, so that the fuse is completely pulled out from the static contact, and the handle and the base can also be easily withdrawn from the base, which is convenient for the installation of the switch and the safe dismantling of the fuse.
2
The structure of the switch is simple, easy to disassemble and assemble. Its base is made of glass fiber reinforced unsaturated polyester molding compound. Its base, handle, arc extinguishing cover, etc. are all pressed by arc-resistant plastic, which has good mechanical strength, flame retardant performance and dielectric properties. The arc extinguishing cover is equipped with multiple metal arc extinguishing grids, which strengthens the arc extinguishing ability of the switch, eliminates the harm of arcing, and improves the service life of the contact.
3
The switch can be operated with load. The first current transformer and bar switch are integrated, with the upper and lower inlet and outlet lines convenient for adjustment. It can be single-phase independent breaking, and can also be three-phase simultaneous breaking. It can be inserted into the fuse for the contact force, or can be directly used with the blade as the isolation switch.
