Brush holder QF-110-2-13.8 is a special brush holder for power plant generators. It is designed to provide stable support and precise positioning for the brushes to ensure good electrical contact between the brushes and the collector rings. The brush holder is usually made of materials such as copper alloys with excellent conductive properties. It has high-strength mechanical properties and corrosion resistance, and can adapt to the harsh working environment of high temperature and high speed inside the generator.

Structure and function

1. Exquisite brush grip design

The brush holder QF-110-2-13.8 adopts a left and right split handle structure, which consists of a conductive ring, a brush holder and a wind cover. This structural design makes the brush holder more convenient during installation and maintenance, and can effectively insulate the ground to avoid current leakage. The brush holder is equipped with a constant-pressure disc spring, which can radially apply stable and constant pressure to the carbon brush, ensuring that the brush does not need to adjust the spring pressure before the length reaches the wear limit, thereby ensuring the close fit between the brush and the collector ring and achieving stable current transmission.

2. High-quality brush configuration

The brushes matched with the brush holder are usually made of natural graphite materials, which have low friction coefficient and self-lubricating effect. Each brush has two flexible copper leads (i.e. brush braids) to ensure the stability of current transmission during the rotation of the brush. This design of the brush not only improves the service life of the brush, but also effectively reduces the wear and heat of the brush during operation, further improving the operating efficiency and reliability of the generator.

3. Good heat dissipation performance

The brush holder QF-110-2-13.8 fully considers the heat dissipation problem in its design. A fan is provided between the two collector rings, which can effectively cool the slip rings and brushes, reducing the risk of damage to the brushes and collector rings due to high temperature. This heat dissipation design ensures the long-term stable operation of the brush holder in a high temperature environment, reduces the downtime caused by overheating, and improves the production efficiency of the power plant.

Technical parameters and performance characteristics

1. Key technical indicators

The technical parameters of the brush holder QF-110-2-13.8 are closely matched with the operating requirements of the generator. Its rated voltage and current can meet the working requirements of the power plant generator at different power levels, ensuring stable and reliable current transmission between the brush and the collector ring. At the same time, the mechanical strength and corrosion resistance of the brush holder can also adapt to the complex working conditions inside the generator, ensuring that it will not be deformed or damaged during long-term operation.

2. High performance

The brush holder performs well in practical applications. Its precise structural design and high-quality material selection make the contact between the brush and the collector ring more stable and the current transmission more efficient. During the operation of the generator, the brush holder can effectively reduce the wear and heat of the brush, extend the service life of the brush, and reduce maintenance costs. In addition, the reliability and stability of the brush holder also greatly improve the overall operating efficiency and safety of the generator, providing a strong guarantee for the stable production of the power plant.

Application scenarios and importance

1. Core application in power plant generators

In power plant generators, the brush holder QF-110-2-13.8 is mainly used to fix and support the brushes to ensure reliable electrical contact between the brushes and the collector rings, thereby effectively transmitting the current in the rotor winding to the external circuit. Its stability directly affects the output power and operating efficiency of the generator. A brush holder with excellent performance can ensure that the generator remains stable under long-term, high-load operating conditions, avoiding power drop or fault shutdown of the generator due to poor brush contact or unstable current transmission.

2. Convenience of maintenance and replacement

Taking into account the continuous operation requirements of power plant generators, the design of the brush holder QF-110-2-13.8 fully takes into account the convenience of maintenance and replacement. The left and right petal structure of the brush holder makes it unnecessary to disassemble the entire brush holder when replacing the brushes. Only one side of the brush holder needs to be opened to replace the brushes. This design not only saves maintenance time, but also reduces the workload of maintenance personnel and improves the production efficiency of power plants.

As a key component of the generator in the power plant, the brush holder QF-110-2-13.8 provides a solid guarantee for the stable and efficient operation of the generator with its exquisite structural design, high-quality material selection and excellent performance. Its outstanding performance in brush fixing, current transmission, heat dissipation and cooling not only improve the operating efficiency and reliability of the generator, but also reduces maintenance costs and failure risks. In the daily production of the power plant, the correct installation, use and maintenance of the brush holder QF-110-2-13.8 is of great significance to ensure the long-term stable operation of the generator.
