12kv/24kv Engineering Type Bypass Sf6 Outdoor Load Switch Circuit Breaker

The bypass comprehensive action technology is a new type of operation technology that improves the reliability of power

supply in the distribution network. It includes various operation methods such as conventional distribution network

operations, live line operations, bypass operations, and mobile power supply operations. The 12kV/24KV engineering type

bypass load switch is the core equipment that meets the comprehensive new operation technology of the bypass. This

switch uses flexible power cables, self-locking quick plug-in cable connectors, bypass switches, mobile box transformers,

and other equipment to build different distribution units in a modular combination to provide bypass power to users. It can

not only enable distribution operators to complete line maintenance work under uninterrupted power supply, but also provide

temporary power supply for difficult to handle cable line faults, narrow the scope of power outages, reduce the impact of

power outages on users, and improve power supply reliability. The bypass load switch adopts SF6 gas with outstanding

insulation and arc extinguishing performance and advanced main circuit structure. The switch features are as follows:

1.1. The interior of the body is injected with high-purity (99.9%) SF6 gas with outstanding insulation and arc extinguishing

performance, so the arc breaking time is short (1/2 Cycle), the insulation recovery speed is fast, and the insulation

performance is good.

1.2. The very short arcing time during load current breaking has little consumption on the contacts at the breaking point,

so there is no need to maintain or replace the main circuit.

1.3. The main circuit operating mechanism is a simple inverted triangle structure (Trigger), which is not affected by high-

frequency vibrations, gravity, external impacts, etc. caused by earthquakes or strong winds. Its performance is very stable

and its mechanical life is long.

1.4 The surface of the body is made of SUS304 stainless steel treated with paint, so it will not be corroded. The operating

mechanism and mechanical transmission part are also installed inside the sealed body, so there will be no malfunction

due to corrosion.

Even at atmospheric pressure (0 kg · f/C ), its insulation and breaking performance can be fully guaranteed. Even if the

SF6 gas inside the body leaks and its pressure drops to 0, it can still ensure all insulation and breaking performance.

1.6 With Charged current display and counting display;

1.7 Possess nuclear phase function

1.8 has manual operation, electric operation, and remote control opening and closing functions (optional), making

operation convenient, fast, and safe.

1.9 Equipped with fault detection, alarm, and automatic fault cutoff functions (optional) for easy fault detection and protection.
