Product Description

Product Description

FLW34-12/40.5kV pole-mounted SF6 load switch is a complete set of pole-mounted switch products developed in accordance with primary and secondary fusion standards. The switch has a compact structure, reasonable layout, and complete functions. All indicators meet the primary and secondary fusion technical requirements. It is Complete set of products for outdoor power distribution automation pole-mounted switches. The load switch adopts the SF6 arc extinguishing principle and has built-in high-precision current transformers, zero-sequence current transformers, and zero-sequence voltage sensors. This complete set of switches can be applied to load currents and overloads in the breaking and closing systems of medium-voltage distribution networks. current, capable of automatically isolating faulty distribution line sections.

First and Second Fusion Features

Primary SF6 Load Switch Part:

1. The body uses high-purity (more than 99.9%) SF6 gas with good insulation and arc-extinguishing properties. It has extremely short arc-extinguishing time (1/2 cycle) and good insulation recovery characteristics, and has superior insulation performance. In addition, the arc extinguishing time when the load current is interrupted is very short, and the contact consumption of the breaking part is small, so there is no need for maintenance and replacement of the breaking part.
2. The switch box is made of 304 stainless steel to meet the corrosion resistance requirements for permanent use.
3. The spring energy storage operating mechanism is adopted, the energy storage is maintained mechanically, and the manual, electric quick-closing and quick-opening operations are adopted. It has fast opening and closing within less than 60ms, and has good compatibility with the backup protection device protection.
4. Equipped with a manual locking mechanism to avoid misoperation during maintenance and improve the safety factor.
5. Equipped with a high-pressure pressure relief device, even if an internal failure occurs, the box will not be damaged due to a sudden increase in gas pressure in the box.

Secondary Intelligent Controller Part:

1. Comply with IEC 61850 standard to achieve plug and play.
2. It adopts high-performance digital signal processor and large-scale field programmable logic array, has powerful real-time data processing capabilities and rich memory resources, and meets the application requirements of advanced application software and communication, system management, human-computer interaction and other functions.
3. It can be flexibly configured according to needs to facilitate the realization of "two remote" or "three remote" functions.
4. Modular and standardized structure, using high-speed real-time serial bus, flexible expansion and easy maintenance.
5. Based on the real-time Linux operating system, it adopts a hierarchical and modular software structure. Applications access underlying resources and data through open interfaces, separate data from applications, and support dynamic loading and unloading of applications. Applications are plug-and-play. Provide a unified support platform for various smart distribution network applications.
