GW9-10/1000A Porcelain Single Phase High Voltage Disconnect Switch Vaccum Outdoor Disconnector

Product Decription:


GW9-10/1000A Single Phase High Voltage Disconnect Switch is an electrical switch used for isolating a single-phase high voltage circuit from its power source. It is typically used in power distribution systems to provide a safe means of disconnecting power to a specific section of the circuit for maintenance or repair purposes.The switch typically consists of a set of contacts that can be opened or closed manually or automatically, depending on the application. When the switch is in the closed position, current can flow through the circuit, and when the switch is open, the circuit is disconnected from the power source.

Structure:



This product is composed of base (plate), post insulator, conductive part and interlock device. One end of the knife is installed on the dynamic contact knife head through bolts, and the other end of the knife is separately connected with the static contact head, and each side is maintained in a good contact state by the pressure of the compression spring. Each knife is slot-shaped type, which not only increases the heat dissipation surface of the knife, but also conducive to reducing the temperature rise, and improve the mechanical strength of the knife, making the dynamic thermal stability against short circuit. The interlocking parts installed at the non-rotating end of the contact knife and the static locking hook on the static contact constitute the opening locking device, which is self-locking when the brake is closed, so that the brake knife will not fall off by itself due to its own weight or the action of electric power, resulting in the opening of the brake without cause.

Operation:


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.
