The specialized fuses for BR2, BR1, BRW, BRN, BRW2, BR, RN, RNY1, RNG, RW high-voltage capacitors have passed various tests of the Quality Inspection and Testing Center for Reactive Power Compensation Equipment of the Ministry of Electric Power, and have passed the commissioning verification jointly organized by the Department of Machinery Industry of Liaoning Province and the Northeast Power Management Bureau. All performance indicators meet the specifications specified in DL442-91 "Technical Conditions for Ordering and Acceptance of Fuses for Single External Protection of Parallel Capacitors".

Purpose:
The BRW (N) series products are mainly suitable for single external protection of high-voltage parallel capacitors in power systems, used to cut off faulty capacitors and ensure the normal operation of other capacitors.

Features
1. Adopting single end exhaust;
2. Adopting a double-layer arc extinguishing structure and equipped with efficient de ionization agents to ensure small capacitive current interruption.
3. Using an external tension spring, combined with an arc extinguishing tube, makes arc extinguishing more reliable during disconnection.
4. Adopting a special crimping structure to solve the problem of excessive temperature rise during operation.

Scope of Application
1. The altitude generally does not exceed 1000 meters.
2. The ambient temperature is between -40 �� and 50 ��.
3. The environment is free from severe pollution and chemical corrosive gases.

�� Power frequency withstand voltage: 70kV
�� Anti surge multiple: greater than 100 times
�� Explosion resistance: 15.6kJ
�� Breaking capacitive low current: 1.5 times the rated current of the fuse
�� Rated capacitive current for breaking: 20 times the rated current of the fuse
�� Fuse specification: 1-50A
Note: �� represents the rated current value

Structure and its characteristics
This type of fuse is composed of an outer arc extinguishing tube, an inner arc extinguishing tube, a fuse, an outer tension spring, and an action indicator board; The external arc extinguishing tube is composed of epoxy glass cloth tube and reverse white steel paper tube, which meets the requirements of capacitive high current breaking performance. The internal arc extinguishing tube is the first to use high-efficiency release agents. When the fuse melts and an arc is generated, the release agent releases high-efficiency non combustible gas, which greatly increases the ionization speed of the release agent compared to the arc ionization speed, quickly extinguishing the arc. Then, it is combined with an external tension spring to pull out the fuse tail wire. Therefore, its arc extinguishing ability is significantly higher than the ability to produce gas arcs solely through reverse steel paper tubes. In addition, the insulation material used for the fuse has an extremely low water absorption rate, making it less susceptible to moisture and deformation, and suitable for indoor and outdoor installation and use.
