Overview

WVK-40.5 Solid-closure indoor high-voltage vacuum circuit breaker is after secondary retrofit design research and development of products and in the company independent research and on the base of WVS-12 series products. It has the leading domestic level. This product adopts integral layout and installation, in the form of a type and floor type two installations, sophisticated technology to ensure the product quality.

Institutions

1. The optimization of the structure of the layout design makes the operability of the product more accord with human body engineering principle, manipulation of the performance;

2. The chassis electrostatic pensu and 80% mechanism parts plating ni-p alloy surface treatment technology, the use of the product appearance quality and excellent internal quality is the same;

3. The use of secondary trip mechanism make the product switch trip operation work fell dramatically, closing is more reliable;

4. The use of secondary spur gear transmission energy storage structure make energy storage is more stable, more compact structure.

Major loop

1. Circuit breaker adopts solid insulation structure, collection of advanced epoxy cement technology will vacuum arcing chamber, conductive loop, insulation support, etc., combined with become enclosed column, successfully solve the environment tolerance capacity of vacuum circuit breaker, application more widely, but also made it possible to product miniaturization;

2. Use unique R contact circuit breaker, it has good performance in applications such as capacitance;

3. The characteristic of the vacuum arcing chamber soft package process to make solid polar column high insulation quality more excellent.
