Single Phase High Voltage Isolator Switch Outdoor Used For Substation For Circuit Breaker
Product Description:
High Voltage Isolator Switch is a type of portable device used for
isolating and grounding electrical distribution lines for
maintenance, repair, or emergency purposes. It is a versatile tool
that can be used in a variety of applications, including overhead
distribution lines, substations, and industrial facilities.
The Isolator Switch is designed to be operated by a single person,
making it easy to use and maneuver. It consists of a telescoping
fiberglass pole, which can be extended to reach the electrical
equipment, and a set of interchangeable attachments, which allow
the user to perform a variety of tasks, such as opening or closing
switches and grounding lines.
The isolator switch is designed to provide a visible break in the
electrical circuit, which helps protect against accidental contact
with energized equipment. It is also designed to withstand harsh
environmental conditions, such as high winds, rain, and snow,
making it suitable for use in outdoor environments.
Condition:
1.The maximum altitude for installation should not exceed 1000m.
2.The ambient air temperature should not exceed +40'C, and in
general areas, it should not fall below -30'C. In Paramos areas, it
should not fall below -40'C.
3.The wind pressure should not exceed 700Pa, corresponding to a
wind speed of 34m/s.
4.The isolator should be able to withstand earthquakes of up to 8
degrees in intensity.
5.The isolator should be installed in a location where there is no
frequent violent vibration.
6.For ordinary type isolators, they should be kept away from gas,
smoke, chemical deposition, salt-spray fog, dust, and other
explosive and corrosive materials that can seriously affect the
isolator's insulation and conduction capability.
7.Pollution-proof type isolators are suitable for use in severely
filthy conduction areas, but they should not be installed in areas
with any explosive or fire-causing materials.
1.Closing the Switch: When the switch is closed, the two conductive parts of the circuit
are brought into contact with each other, allowing electrical
current to flow through the circuit.
2.Opening the Switch: When the switch is opened, an air gap is created between the two
conductive parts of the circuit, effectively isolating the section
from the rest of the system. This is typically done to allow
maintenance, repair, or testing work to be carried out safely.
3.Grounding the Circuit: Before any work can be carried out on the isolated section of the
circuit, it is important to ground the circuit to prevent any
residual electrical charge from building up. This is typically done
using an earth switch or grounding electrode.
It is important to note that the operation of high voltage isolator switches should only be carried out by trained and qualified personnel, as they can pose a serious risk of electrical shock or injury if mishandled. In addition, it is important to follow all safety procedures and guidelines when working with high voltage equipment, including wearing appropriate protective clothing and equipment, using insulated tools, and ensuring that the area is clear of any flammable or explosive materials.
1.Isolation: The switch is used to isolate a single phase of the
power system for maintenance or repair purposes.
2.High Voltage Rating: These switches are designed to handle high
voltage levels, typically ranging from a few kilovolts to several
hundred kilovolts.
3.Manual Operation: The switch is manually operated using a
hookstick or a lever. The operator must be trained in the safe
operation of the switch.
4.Visual Indicators: Some switches have visual indicators that show
whether the switch is open or closed, making it easier for
operators to know the status of the circuit.
5.Durability: These switches are designed to withstand harsh
environmental conditions, such as extreme temperatures, humidity,
and corrosive substances.
6.Safety Features: The switch is designed with safety features to
protect operators from electrical hazards, such as insulating
materials that prevent accidental contact with live parts.
7.Compact Size: Single-phase high voltage isolator switches are
typically compact in size and can be installed in tight spaces.
