Importance and application of operating handle for railway power supply equipment

In the field of modern transportation, railway transportation has attracted much attention because of its characteristics of safety, speed and large volume. In the whole railway system, power supply is one of the important guarantees for its normal operation. Therefore, for railway power supply equipment, the design and use of operating handle is even more important.

1. What is the operating handle of railway power supply equipment?

The operating handle in railway power supply equipment refers to the switching equipment used to control and adjust electrical devices. It is usually installed on various high-voltage circuit breakers, disconnectors and other electrical appliances, so that workers can manually operate and complete the closing or opening of the circuit. The operating handle should not only have good mechanical properties, but also meet the requirements of insulation and corrosion protection.

Second, the function and classification of the operating handle.

According to different application scenarios and technical requirements, the operating handles in railway power supply equipment are divided into many types:

1. Manual handle operation: the mechanism is mainly driven by human rotation to realize the function of opening or closing;

2. Electric operating handle: the motor is used as the power source to drive the actuator to work, which can realize remote control operation;

3. Spring energy storage type operating handle: a spring structure is arranged inside to store energy, and when an instruction is received, the energy is released to complete the switching action;

4. Operating handle of vacuum interrupter: it is suitable for vacuum switchgear and has good arc extinguishing effect.

Third, what aspects should be paid attention to when choosing the appropriate operating handle?

In order to ensure the stability and reliability of railway power supply system, the following factors should be considered when purchasing operating handles:

1. Select products with corresponding models and specifications according to specific application scenarios, such as the matching of parameters such as voltage grade and current size;

2. Pay attention to the quality of products and the level of production technology, especially the selection of contact materials, because it directly affects the quality of electrical conductivity;

3. Investigate the technical strength and service system of suppliers, including whether there is a perfect after-sales service network to support on-site debugging and maintenance.

Fourth, summary.

In a word, it is very important to reasonably select high-quality operating handles in railway power supply equipment to ensure the safety and reliability of the whole power grid. I hope this article can help readers understand the relevant knowledge in this field more deeply and provide some reference suggestions for enterprise procurement personnel.
