High-Voltage Current-Limiting Fuse Is Used for Transformer Protection (XRNT-HRC fuse) 3.6kv/7.2kv/12kv/24kv/40.5kv

Application: 

high voltage current limiting fuses type seires mainly used in AC50hz, rated voltage 3.6-40.5KV.Rated current up to 200A circuit for protection transformers and power equipments form overload and short circuit .it can also be used with load switch ,vacuum contact. it conforms to IEC282-1,GB15166.2 and DIN standard.

 

Design features: 
S type high voltage HRC current limiting fuses is insert installation,the striker parallels to the fuse element made from pure silver.they are sealed in the fuse tube filled with chemically treated high purity quart sand.the fuse tube is made from heat resistance.high duty ceramic or expoxy glass.when fault circuit happpens .the fuse link melts.the high resistant metal wire paralleling to fuse links metlts immediately at the apperance of the arc.and the striker jumps out to push the chained equipment contact .signaling the melting automatically cutting the circuit.the striker has spring type striker use high pressure caused by the lighting power to push the striker.S type high voltage HRC current limiting fuses has many merites as high current limiting ability .high breaking capacity .quick and punctual in action .reliable in performance.

 

DIN HRC "S" type high voltage fuse for transformer protection:

1. According to bussmann DIN "S" type high performance back-up fuse

. Comply with IEC282-1, DIN, BS

3. This fuse is intended to protect distribution networks and transformer, for indoor as well as outdoor use.

4. Any other specifications can be designed specially.

 

 

Miniature Slip Ring

What is a miniature slip ring? Miniature slip rings are rotary electrical connectors that allow power and data to be transferred between a stationary and rotating structure. They are often used in medical, military, and aerospace applications where size and weight are critical factors.

A miniature slip ring typically consists of two parts: a stationary housing and a rotating contact assembly. The contact assembly contains the brushes that make electrical contact with the rotating structure, as well as the rings that conduct current or data.

The housing can be made from any number of materials, including metals, plastics, and composites. It is typically designed to be as small and lightweight as possible while still providing adequate strength and durability.

The contact assembly is made from precious metals such as gold or silver in order to provide good electrical conductivity.

Technology improves with the continuous development of precision machinery. The more sophisticated the equipment, the smaller the volume will be. And the space that can be accommodated for installing the slip ring is also very small. The key parts of some equipment are quite a district. Especially in the high-end military, aerospace and aviation fields. 360-degree rotation is required to transmit current and signals. And the installation space is greatly reduced. It is to make the equipment work more smoothly. Therefore, it is necessary to design the slip ring to be small and exquisite. Otherwise, it won't meet the needs of the installation.

At the same time, we have moved with the continuous development of science and technology. Various high-end precision instruments have been developed. It requires the slip ring to transmit the current amount of general power. Also often undertake the transmission of weak electrical signals and various weak signals. The transmission medium is wider, and the number of loops of the slip ring is increasing.
