Product Description

Product Description

Structural features
It is mainly composed of a frame, disconnector, vacuum switch tube, grounding switch, spring operating mechanism, etc.
The product has a compact structure and small size, which is easy to install and arrange.
The spring operating mechanism can realize the spring energy storage of the motor (manual operation is optional), and the closing mode includes electromagnetic closing and manual opening and closing.
The disconnector, vacuum switch and grounding switch are interlocked with each other (mechanical interlocking) to prevent misoperation.
Working principle
Using vacuum as the arc extinguishing medium, the vacuum arc extinguishing chamber has extremely high insulation performance and can quickly extinguish the arc. When the switch is disconnected, the arc quickly spreads and cools in a vacuum environment, thereby realizing the rapid cutting of the current and effectively avoiding the damage of the arc to the inside of the switch.

Technical parameters
Rated voltage: 12kV.
Rated insulation level: power frequency withstand voltage to ground/isolation break is 42/48kV, lightning impulse withstand voltage to ground/isolation break is 75/85kV.
Rated current: There are different specifications such as 630A, 800A, 125A, etc.
Rated active load breaking current, rated closed-loop breaking current: corresponding to the rated current specifications, such as 630A, 800A, 125A, etc.
Rated short-time withstand current (2S): 20kA.
Rated short-circuit closing current, rated peak withstand current: 50kA.
Mechanical life: 5000 times or 10000 times.
Applications
It can be used as the main component of ring network cabinets, box-type substations or other types of switch cabinets, and is used for the control and protection of power equipment such as transformers, cables, overhead lines, etc.
It is widely used in power distribution systems such as factories, residential areas, high-rise buildings, schools, parks, etc. It is suitable for urban distribution stations and industrial power equipment with three-phase ring networks or terminal power supply for load control and short-circuit protection.

Circuit Breakers & Switch /Isolating Switch

FZ(R)N25-12 Vacuum Load Switch

eneral	LBIS Type outdoor on load break switch disconnector contained in this list are destined to switch stub lines and ring main lines or transformers (It can be equipped with MV HRC fuse links as short circuit protection fuction) or for switching under on load conditions. This disconnector complies with IEC/IEEE and DVE-recommendation standards especially comply with DIN VDE 0670 part 3 and IEC 60265, IEC 129.
Features	All steels are made of either in stainless steel or hot-dip galvanized steel.  1. Solid and stable base frame.  2. main contact with ice protection.  3. Polymer insulators or alternatively in porcelain.  4. Minimal sag for the line-connection between two fixed terminals.  5. Completely maintence antirust Aluminium alloy Arc chamber.  6. Switching-off procedure without external arc.  7. Short circuit making capacity under specific conditions possible  8. Fixing on the supporting structure either by clamping(free setting) or screwing (holes in the   base frame)  9. Easy on-site installation and setting.  10. High reliabilty up to 1000 cycles (depending on the running current).  11. All contacts are either sliver or tin-plated.  12. Practically maintance-free.
