HGRW1-35/200A
Short Description:
A fuse is a protective device for overload and short circuit faults in the power system. When the current exceeds a given value for a certain period of time, it uses the heat generated by itself to melt the melt and open the circuit as a switching device.
Product details
1、 Technical characteristics
A fuse is a protective device for overload and short circuit faults in the power system. When the current exceeds a given value for a certain period of time, it uses the heat generated by itself to melt the melt and open the circuit as a switching device. Fuses have excellent overcurrent protection characteristics, with strong power frequency withstand voltage capability, high lightning impulse withstand voltage, large breaking current, and high mechanical strength.
Our company has excellent fuse production assembly lines, equipped with fuse testing equipment such as power frequency withstand voltage, lightning impulse, partial discharge, DC resistance, and strict quality assurance system.
The combination of isolation switch and fuse is an outdoor high-voltage protection electrical device with a drop off function. It is an excellent product specifically designed to replace old models of drop out fuses, suitable for wind farms, petroleum, chemical, steel, and power stations as an essential product for protecting sections. It is assembled on the high voltage side of distribution transformers or distribution line support lines, and is used for overload and short-circuit protection of transmission lines and power transformers, as well as for dividing and combining rated load currents. It has simple operation, easy maintenance, and effectively solves the problem of no fault falling. The improvement of this product is mainly aimed at factors such as fault free drop, high current operation, and instability. Improved the isolation switch function to the fuse body, while retaining the protection function of the fuse, with the ability to disconnect short-circuit current and fault current.
Product advantages:
This product is specially designed to meet national technical standards and has creative and practical functions.
① The product uses synthetic silicone rubber material as the insulator, and the central material uses an insulating pull rod.
② The switch contacts are made of steel, phosphor bronze material, and stainless steel material.
③ The standard connecting parts are made of stainless steel (304 material).
④ The switch action part consists of die cast copper parts and fiberglass wrapped tubes.
⑤ The upper moving contact of the melting tube is designed as a double contact combination, and the lower moving contact is designed as a flip contact.
⑥ The static contact on this product is a double contact surface, with a pressure contact method at one point and a card and contact method at the second point.
⑦ The lower static contact is a copper die-casting contact.
