Engineering Type by-Pass Sf6 Outdoor Load Break Switch Circuit Breaker
Description
Bypass association technology is a new engineering work technology to improve the reliability of power supply in the distribution network. It includes various work methods such as regular work of distribution network, live work, bypass work, and movable power source work.
BP-LBS 12kV/24KV engineering bypass load break switch is the core equipment to meet the comprehensive new engineering work technology of bypass. This switch uses flexible power cables, self-locking quick plug-in type cable connectors, bypass switches.It can not only enable power distribution workers to complete line maintenance work under uninterrupted power supply status, but also provide temporary power supply for emergency repairs of cable lines that are difficult to handle, reduce the scope of power outages, reduce the impact of power outages on users, and improved power supplyreliability. The bypass load break switch adopts SF6 gas with outstanding insulation and arc extinguishing performance and advanced main circuit structure.
Product Features 1. Inside the switch main body is filled with high-purity (99.9%) SF6 gas with outstanding insulation and arc extinguishing performance, thus the arc breaking time is short (1/2 Cycle), the insulation recovery speed is fast, and the insulation performance is excellent. 2. The main circuit operating mechanism is a simple inverted triangle structure (Toggle), so it will not be affected by high-frequency vibration, gravity, external impact, etc. caused by earthquakes or strong winds, and it has very stable performance and long mechanical life.
3. The surface of the main switch body is made of painted SUS304 stainless steel, so it will not be corroded. The operating mechanism and mechanical driveparts are also installed inside the sealing body, so there will be no misoperation due to corrosion.
Main function features: 1. The filled-in gas is high-purity SF6 gas featuring short arc breaking time(1/2 Cycle),high insulation recovery speed and good insulation performance. 2. No need to maintain or replace the breaking contacts since very short arcing time only causes very little consumption to the contacts during the making or breaking of the load current. 3. The main circuit operation mechanism is the simple reversed triangular structure, so it can not be affected by high-frequency vibration, gravity force and external shockscaused by earthquake or wind. It has features of stable performance and long mechanical life. 4. The product cannot be eroded since the tank is made of the stainless steel which is treated by spray-painting. The operation mechanism and action parts are built inside of the tank, so erosion can be avoided and wrong action will not occur. 5. The insulation performance and breaking performance can be entirely guaranteed under the atmospheric pressure(0 kg·f/cm2), i.e. even the inside SF6 gas leaks and the pressure drops to zero, the product also can ensure the insulation performance and breaking performance.
With current display and count display,With phase-check function,It has manual operation, electric operation, can be with remote control opening and closing function if need (optional), and the operation is convenient, fast and safe. With fault detection, alarm function,can be with automaticfaultcut-off function if need (optional), convenient for fault detection and protection.
