Single Phase Outdoor Disconnector Switch High Voltage 30kV For Substation Loadbuster Disconnect Switch
Product Decription:
Single Phase Outdoor Disconnector is a type of electrical switch that is designed to be operated remotely using a hookstick or a long pole. It is typically used in power distribution systems, where it is necessary to isolate a portion of the system for maintenance or repair work.
The interlocking parts installed at the non-rotating end of the contact knife and the static locking hook on the static contact form the opening locking device. When the brake is closed, the device is self-locking, so the brake knife will not fall off due to its own weight or the action of electric power, which could cause the brake to open without cause.
The hookstick switch is designed to be operated remotely using a hookstick or a long pole, which allows the operator to stay at a safe distance while performing maintenance or repair work. This eliminates the need for the operator to climb up to the switch, which can be dangerous and time-consuming.
Safety is of utmost importance when working with hookstick switches. These switches can be extremely dangerous if not handled properly. Therefore, only qualified and trained personnel should be allowed to operate and maintain high voltage equipment. It is important to follow proper safety procedures to ensure the safety of individuals and the proper functioning of the electrical system.
Application:
1.Power Distribution Systems: The switch is commonly employed in power distribution networks to isolate specific sections of the circuit for maintenance, repair, or troubleshooting purposes. It allows technicians to safely work on a particular portion of the system without interrupting power to the entire network.
2.Substations: High voltage disconnect switches are commonly used in electrical substations to provide a means of isolating equipment, such as transformers or circuit breakers, from the power source. They facilitate maintenance, repair, or replacement of substation components without affecting the overall power supply.
3.Industrial Facilities: The switch is used in industrial settings where single-phase high voltage circuits are present. It allows for the safe disconnection of equipment or machinery during maintenance or repair activities, ensuring the safety of personnel and protecting the equipment from damage.
4.Renewable Energy Systems: In renewable energy installations, such as solar or wind power systems, high voltage disconnect switches are used to isolate specific sections of the system for maintenance or repair work. They provide a safe way to disconnect the power source from components like inverters, batteries, or grid connection points.
5.Testing and Measurement: The high voltage disconnect switch is often utilized in testing and measurement applications. It allows for the isolation of specific sections of a circuit to perform accurate measurements, analysis, or diagnostic tests without interference from other connected components.
Condition:
1.The altitude does not exceed 1000m
2.The ambient air temperature: Maximum+ 40'C ;Minimum:General Area -30'C, Paramos -40 C;
3.The wind pressure does not exceed 700Pa.(corresponding to 34m/s wind speed);
4.The earthquake intensity does not exceed 8 degrees;
5.The working situation is without frequent violent vibration;
6.The installation site of ordinary type isolator should be kept away form gas, smoke chemical deposition, salt-spray fog, dust
and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator
7.Pollution-proof type isolator is applies to severe filthy conduction area, however, it shouldn't be any explosive matters and matters causing fire.
Safety Tips:
1.Always wear appropriate personal protective equipment (PPE) such as gloves, safety glasses, and flame-resistant clothing.
Before working on the switch, ensure that the power supply is turned off, and the switch is properly grounded.
2.Follow the manufacturer's instructions for operating the switch, and do not attempt to bypass safety features or use the switch for purposes other than its intended use.
3.When working on the switch, use insulated tools and equipment to prevent electric shock.
4.Avoid touching any conductive parts of the switch and keep a safe distance from the switch when it is in operation.
5.Never attempt to repair or modify the switch yourself unless you are a qualified and trained professional.
6.Keep the area around the switch clean and free of debris that may interfere with its operation.
7.Regularly inspect the switch for signs of wear or damage, and replace any damaged or worn parts as soon as possible.
8.Only authorized personnel should be allowed to operate or perform maintenance on the switch.
9.In case of an emergency, follow established emergency procedures and shut off power to the switch immediately.
