Product Description:

High Voltage Electrical Isolator is a type of electrical switch used in power systems to isolate a circuit from the rest of the system for maintenance or safety purposes. The term "vertical" refers to the orientation of the isolator, which is mounted vertically on a support structure.

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 designed to handle high voltages and currents and are often installed in outdoor locations.

High Voltage Electrical Isolators typically consist of a set of stationary and movable contacts that are separated by an air gap. When the isolator is in the closed position, the contacts are in contact with each other, allowing current to flow through the circuit. When the isolator 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.

Application:

1.Circuit isolation: High voltage electrical isolators are primarily used to isolate sections of a power system for maintenance or repair work. This allows workers to work safely on the isolated circuit without the risk of electrocution or other electrical hazards.

2.Safety: High voltage electrical isolators are also used as a safety device to protect workers and the public from electrical hazards. By isolating a circuit, High voltage electrical isolators prevent accidental contact with live parts of the system and reduce the risk of electrical accidents.

3.Fault protection: High voltage electrical isolators can also be used to protect the power system from faults, such as short circuits and overloads. By isolating a faulty section of the system, High voltage electrical isolators prevent the fault from spreading to other parts of the system and causing further damage.

4.Switching: High voltage electrical isolators can be used as a switching device to control the flow of power in a system. By opening or closing the isolator, the flow of power can be directed to different parts of the system as needed.

5.Testing: High voltage electrical isolators can also be used for testing purposes, such as to measure the voltage or current in a circuit, or to test the performance of other components in the system.

Feature:

1.High Voltage Rating: High voltage isolator switches are designed to withstand high levels of voltage, typically ranging from several thousand volts to several hundred thousand volts.

2.Robust Construction: High voltage isolator switches are typically made of materials that are highly resistant to electrical arcing, corrosion, and other forms of damage, such as porcelain or polymer.

3.Arc Chutes: Many high voltage isolator switches are designed with arc chutes, which help to dissipate the heat generated by electrical arcing and prevent damage to the switch.

4.Earth Switch: Some high voltage isolator switches are equipped with an earth switch, which provides an additional level of safety by grounding the isolated section of the circuit.

5.Interlocking Mechanism: To prevent accidental closure of the switch while maintenance work is being carried out, many high voltage isolator switches are equipped with an interlocking mechanism that prevents the switch from being closed until all safety procedures have been followed.

6. Visual Indicators: High voltage isolator switches may also include visual indicators, such as lights or flags, that provide a clear indication of whether the switch is in the open or closed position.

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.

Condition:

1.The maximum altitude in the specified area does not exceed 1000 meters above sea level. This altitude limitation is relevant for the installation and operation of the equipment.

2.The ambient air temperature has certain limits. The maximum temperature should not exceed +40°C, and the minimum temperature can vary depending on the specific area. In general areas, the minimum temperature should not drop below -30°C, while in Paramos areas, it should not drop below -40°C.

3.The wind pressure should not exceed 700 Pascal (Pa), which corresponds to a wind speed of approximately 34 meters per second. This limit ensures that the equipment can withstand the force exerted by the wind without compromising its functionality or structural integrity.

4.The earthquake intensity should not exceed 8 degrees. This refers to the maximum intensity of seismic activity that the equipment can withstand without being damaged. The specific scale used to measure earthquake intensity may depend on the region or country.

5.The working environment should be free from frequent violent vibrations. This requirement ensures that the equipment remains stable and operational under normal operating conditions. Excessive vibrations can affect the performance and lifespan of the isolator.

6.Ordinary-type isolators should be installed in locations that are kept away from gas, smoke, chemical deposition, salt-spray fog, dust, and other explosive or corrosive substances. These materials can have detrimental effects on the insulation and conduction capabilities of the isolator, potentially compromising its performance and safety.

7.Pollution-proof type isolators are designed for use in areas with severe contamination. However, even in such areas, there should be no presence of explosive substances or materials that can cause fire. This requirement ensures that the isolator remains safe and functional despite the challenging environmental conditions.
