Product Description

Isolating Disconnector Switch GN19-12 Indoor 11KV 12KV Medium Voltage 400A 630A 1000A 1250A Earthing Switch

Product Description

 

Product Description

GN19-12 indoor HV disconnect switch applies to power system of rated voltage below 12KV, AC 50/60Hz. It is equipped with CS6-1 manual-operating mechanism and is used to break and make circuit under no-load. There are additional pollution type, high-altitude type and electrified display.

Work Environment

The altitude: 1000m~3000m
The ambient temperature: -30°C~40°C
The relative humidity of air: monthly≤90°C,daily≤95°C
The wind pressure: ≤700pa(wind speed 34m/s)
Amplitude: earthquake degree 8
Environment degree: degree III
Cannot be use on the condition of the danger of fire and blast, heavy pollution, chemical etching, strong shake etc.

Technical Parameter
Main components
Base: the basic structural part of the disconnector.
Post insulator: provides insulation support to ensure the insulation performance of the equipment under high voltage.
Conductive circuit: includes the knife and static contact, which forms an obvious insulation port when opening and ensures reliable connection of the circuit when closing.
Actuating mechanism: can be manual (such as CS17A type) or electric (such as CJ6B type), and the opening and closing operations are realized through mechanical transmission.
Technical parameters
Rated voltage: 40.5kV, 72.5kV, 126kV
Rated current: 400A/630A
Rated frequency: 50Hz
Rated peak withstand current: 50kA
Rated short-time withstand current: 20kA (3 seconds)
Operation mode: manual or electric.
Performance characteristics
Simple structure: simple design, easy to install and maintain.
Strong current capacity: able to withstand large current load.
Excellent insulation performance: high-quality insulating materials are used to ensure the safe operation of the equipment under high voltage environment.
Flexible operation: Flexible opening and closing operations ensure quick response.
High safety: There is a clearly visible break after opening, and the operating mechanism is equipped with an auxiliary switch, which sends a corresponding signal when the opening and closing are terminated to ensure safe operation.
