VCB Metal square oil cup buffer block current release shock absorber for indoor vacuum circuit breaker
The oil buffer is also called a current release. In the case of overload, short circuit and other overcurrents in the circuit, the oil cup will generate a high-strength magnetic field, attract the armature, and then drive the operating mechanism to trip and trip.
Structure
1. The main structure of oil buffer is noumenon, axis, bearings, inner tube, piston, springs and other components. When axial piston driven by external shocks will squeeze the inner tube hydraulic oil,hydraulic oil discharged to drain hole after pressure while the hydraulic oil is discharged from the inner tube back into the oil return hole; when the external force disappears, the spring piston spring back to wait for the next operation of the start point . So the principle, hydraulic buffers will be able to move objects in a balanced and effective stop.
2. The elimination of non-mechanical motion of vibration and impact damage.
3. Significantly reduce noise, providing a quiet working environment.
4. Speed mechanical actuation frequency, increase
5. High-efficiency production of high quality products.
6. A longer life, reduced service.
