ZN63A (VS1)-12 Indoor High Voltage Vacuum Circuit Breaker

Overview

VS1 indoor medium voltage vacuum circuit breaker is a switchgear for three-phase AC 50Hz, rated voltage 6KV, 12KV, 24KV power system.
The circuit breaker adopts the integrated design of the actuator and the circuit breaker body, which can be used as a fixed installation unit or as a separate VCB trolley together with the handcart. Their life expectancy is very long. Even if the operating current and short-circuit current are switched frequently, the vacuum will not be adversely affected.
Our products are widely used in:
1 – Transformers and Distribution Substations
2 – Generator Control and Protection
3 – Capacitor bank control and protection etc.

Product Structure Features

The VS1 type is composed of an operating mechanism and an arc-extinguishing chamber arranged in front and back, and its main conductive circuit is a floor-standing structure. The vacuum interrupter is fixed in the vertical casing insulating column made of epoxy resin by APG technology, which has high creepage resistance. Such a structural design greatly reduces the accumulation of dust on the surface of the vacuum interrupter, which not only prevents the vacuum interrupter from being affected by the outside world, but also ensures a high resistance state to the voltage effect even in a warm and humid environment. climate or heavily polluted environment.
1 – With reliable interlock function, suitable for frequent operation
2 – Low noise and low energy consumption
3 – Simple and sturdy construction.
4 – High operational reliability
5 – Switch mechanical durability: 20000 times etc.

Environmental Conditions

1. Ambient air temperature: -5~+40, 24h average temperature does not exceed +35.
2. Install and use indoors. The altitude of the work site shall not exceed 2000M.
3. At maximum temperature +40, the relative humidity should not exceed 50%. Higher relative humidity is allowed at lower temperatures. predecessor. 90% at +20. However, due to changes in temperature, it is possible to inadvertently produce moderate dew.
4. The installation slope should not exceed 5.
5. Install it in places without severe vibration and impact, and in places with insufficient corrosion to electrical components.
6. For any specific requirements, please negotiate with the manufacturer.
