HengAnshun High Voltage Electrical Isolator Stainless Steel Ceramic

Grey Color High Voltage Electrical Isolator Made By Steel/Stainless Steel/Ceramic Outdoor Disconnector Switch

Product Description:

High voltage electrical isolator is a type of electrical switch used in high voltage power systems to isolate sections of the network for maintenance or safety purposes. The switch is typically mounted on a pole or other support structure and is used to disconnect an overhead power line from the rest of the system.

High voltage electrical isolators are designed to handle high voltages and currents and are often installed in outdoor locations. They consist of a set of stationary and movable contacts that are separated by an air gap. When the switch is in the closed position, the contacts are in contact with each other, allowing current to flow through the circuit. When the switch is opened, the contacts are separated, interrupting the flow of current through the circuit and isolating it from the rest of the system.

High voltage electrical isolators are an important component of power system safety and reliability and are designed to operate in a variety of environmental conditions. They are often subject to rigorous testing and certification requirements to ensure that they meet industry standards for performance and safety.

High voltage electrical isolators are commonly used in high voltage transmission and distribution systems to isolate sections of the network for maintenance or repair work. They are also used as a safety device to protect workers from electrical hazards, such as accidental contact with live parts of the system.

Application:

1.Maintenance and Repair: The disconnector switch is used to isolate a section of the power line for maintenance or repair purposes. This allows maintenance personnel to work safely without risking electrocution.

2.Load Shedding: In the event of a power overload, the disconnector switch can be used to shed the load and prevent damage to the power line or equipment.

3.Fault Isolation: The disconnector switch can be used to isolate a section of the power line in the event of a fault, such as a short circuit or ground fault. This prevents the fault from spreading to other parts of the network and causing further damage.

4.Switching Operations: The disconnector switch is used for switching operations, such as connecting or disconnecting power sources or rerouting power to different parts of the network.

5.Protection: The disconnector switch is often used in conjunction with other protective devices, such as circuit breakers and fuses, to protect the power line and equipment from damage.

6.Renewable Energy: With the increasing use of renewable energy sources, such as wind and solar, disconnector switches are used to connect and disconnect these sources from the power grid.

1 Preparation: Before operating the switch, the circuit should be de-energized and properly grounded to prevent any electrical hazards. The switch should be inspected for any signs of damage or wear and tear.
2 Closing the switch: To close the switch, the operator manually or remotely moves the switch handle or control lever to the closed position. This connects the circuit to the power source, allowing current to flow through the circuit.
3 Opening the switch: To open the switch, the operator manually or remotely moves the switch handle or control lever to the open position. This disconnects the circuit from the power source, interrupting the flow of current.
4 Arc management: When the switch is opened, an electrical arc may occur between the contacts, which can be dangerous and cause damage to the switch. To manage the arc, the switch may be equipped with devices such as arc chutes or blowout coils.
5 Safety: Operators of high voltage disconnect switches must follow proper safety procedures to prevent electrical hazards. This may include wearing personal protective equipment, working in teams, and following lockout/tagout procedures.

Feature:

1 Safety: The primary feature of a hookstick switch is safety. It allows maintenance personnel to safely disconnect a circuit from its power source without the risk of electrocution.

2 Remote Operation: The switch can be operated from a safe distance using a long pole or "hookstick," which eliminates the need for personnel to be in close proximity to the high-voltage equipment.

3 Easy to Use: Hookstick switches are designed to be easy to use and require minimal training to operate.

4 Durability: They are designed to withstand harsh environmental conditions, such as extreme temperatures, humidity, and corrosive substances.

5 High Voltage Rating: Hookstick switches are typically used in high-voltage power transmission and distribution systems and have a high voltage rating, ranging from a few thousand volts to several hundred thousand volts.

6 Versatility: They can be used for a wide range of applications, including switching and isolating circuits, as well as for grounding and de-energizing equipment.

7 Visual Indicators: Some hookstick 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.

Structure:

1.Porcelain Insulator Body: The insulator body is the main component of the isolator, and is typically made of high-strength porcelain. It is designed to provide electrical insulation between the conductor and supporting structure, and is molded into the desired shape and size.

2.Metal End Fittings: The metal end fittings are attached to the insulator body and provide a means of connecting the isolator to the conductor and supporting structure. They are typically made of galvanized steel or other corrosion-resistant material, and may be designed with special features such as clevises or ball-and-socket joints for easy installation.

3.Sealing Compound: A sealing compound is used to seal the joint between the insulator body and metal end fittings, preventing moisture and contaminants from entering the interior of the isolator.

4.Hardware: Hardware such as bolts, nuts, and washers are used to secure the metal end fittings to the insulator body and supporting structure.

Fitting Caps: Fitting caps are used to protect the metal end fittings from corrosion and damage, and may be made of plastic or other materials.

5.Additional Features: Depending on the specific application, porcelain high voltage electrical isolators may be designed with additional features such as insulating barriers, arc chutes, and earth switches to improve their performance and safety.
