The GW9-10 High voltage disconnect switches are essential components in power transmission and distribution systems, as they allow for the isolation of specific sections of the network for maintenance or repair work. They can also be used to isolate sections of the network in the event of a fault or other abnormal condition.

These switches are designed to handle high voltages and currents, and are typically constructed from durable and robust materials such as stainless steel, aluminum or copper. They are designed to withstand harsh environmental conditions, such as extreme temperatures, high winds, and heavy rainfall.

There are several types of high voltage disconnect switches, including air-break switches, oil-immersed switches, and gas-insulated switches. Air-break switches are the most common type, and they wor k by using a set of contacts that physically separate when the switch is opened. Oil-immersed switches are typically used in high voltage applications and are filled with oil to prevent arcing when the switch is opened. Gas-insulated switches use sulfur hexafluoride gas to insulate the switch contacts, which allows for smaller and more compact switch designs.

High voltage disconnect switches must be operated and maintained by qualified personnel who have received proper training. Safety procedures must be followed when working with these switches, including the use of appropriate personal protective equipment and following lockout/tagout procedures to prevent accidental energization of the equipment. Regular maintenance and testing of high voltage disconnect switches is also important to ensure that they are functioning properly and are safe to use.

Controller Introduction:

1.With 485 / 232 communication interface, or through optical fiber, wireless remote monitoring; Acceleration function after reclosing;when the switch is heavy,automatic acceleration tripping in case of permanent fault;

2.Remote / manual closing to accelerate tripping, and closing reclosing: The user sends power after repairing the line, if he forgets to remove the grounding switch,should accelerate tripping.

3.Three reclosing delay time can be adjusted;

4.The jump closing circuit adopts anti-misoperation design and has anti-jump function;

5.Zero-sequence current can distinguish between in-zone and out-of-zone faults;

6.The remote control switch is designed to prevent misoperation.

Collocation:

The relation between the outdoor vacuum circuit breaker and the outdoor high-voltage disconnect isolator lies in their complementary roles in the electrical system:

Circuit Interruption: The vacuum circuit breaker is responsible for interrupting the electrical circuit during normal operation or in the event of a fault. It acts as the primary means of breaking the current flow. In contrast, the disconnect isolator is used for isolating the circuit from the power source during maintenance or repair activities. It provides an additional layer of safety by physically opening the circuit.

Coordination: In high-voltage power systems, the vacuum circuit breaker and the disconnect isolator are often coordinated to work together. The circuit breaker is responsible for detecting faults and tripping to interrupt the current flow, while the disconnect isolator is used to physically isolate the circuit and provide a visible indication of the disconnection.

Safety and Maintenance: The disconnect isolator plays a crucial role in ensuring the safety of maintenance personnel. Before any maintenance work can be performed on the electrical equipment, the disconnect isolator is operated to open the circuit and provide a visible air gap. This ensures that the equipment is de-energized and safe to work on. The vacuum circuit breaker, on the other hand, protects the system during normal operation and in the event of faults.
