Main features of VS1 vacuum circuit breaker?

VS1-12 vacuum circuit breaker alias: ZN63A vacuum circuit breaker is independently developed by Zhejiang Xuli Electric Co., Ltd. It is based on the full digestion and absorption of traditional VS1 vacuum circuit breaker technology in the early stage, and is combined with domestic electric locomotive vacuum circuit breakers. The matching design has been improved for specific operating conditions and technological innovation has been achieved. This circuit breaker has the following advantages:

1) The vacuum bubble of the high-voltage circuit part adopts a glue-injection sealing installation method, which greatly improves the insulation performance between poles and increases the stability and reliability of the installation;

2) The drive joystick is made of polymer synthetic material and is integrally formed with an umbrella skirt design, which ensures mechanical strength while increasing the creepage distance and electrical clearance, improving the insulation performance. In addition, it also overcomes the aging problem of traditional silicone rubber umbrella skirts. shortcoming;

3) The drive control part adopts pneumatic components with better high and low temperature performance and intelligent electronic modular control unit board, which greatly improves the product's high and low temperature performance and operational stability;

4) It not only inherits the advantages of foreign vacuum circuit breakers such as large breaking capacity, high insulation performance, and good environmental matching, but also the upright structure reduces the quality and installation space. It can not only be installed on the roof, but also can be installed in the cabinet. It is easy to install and install in an integrated manner, laying the foundation for the development of integrated high-voltage electrical appliances for electric locomotives.

VS1 vacuum circuit breaker technical summary

VS1 vacuum circuit breaker has passed the short-circuit breaking, short-time withstand, operating limits, temperature rise, temperature change, vibration and impact at the Beijing Ministry of Railways Product Quality Supervision and Inspection Center, Xi'an High Voltage Electrical Appliance Research Institute and Suzhou National Electrical Appliance Quality Supervision and Inspection Center. The type test of all standard test items such as mechanical life and mechanical life has verified that the design and performance of the TDV10 vertical vacuum circuit breaker are in line with the current technical standards for the use of main circuit breakers in electric locomotives and fully meet the user's requirements.
