It can be used as a protection and control device in industrial and mining enterprises, power plants, and substations, and is suitable for occasions with frequent operations.

The VS1 series 4000A indoor lateral - type vacuum circuit breaker is a kind of indoor high - voltage switchgear. It is suitable for three - phase AC 50Hz power systems with a rated voltage of 12kV, used as a protection and control device in power systems such as industrial and mining enterprises, power plants, and substations3. It can be installed in fixed - type switchgear or used alone, and is especially suitable for occasions with frequent operations1. This circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body. It can be used as a fixed - installation unit or equipped with a special propulsion mechanism to form a hand - cart unit3.

The LW3 - 12 630A outdoor pole - mounted SF6 circuit breaker is a three - phase AC 50Hz outdoor high - voltage electrical apparatus3. It uses SF6 gas as the arc - extinguishing and insulation medium and adopts a gas - pressure - type arc - extinguishing structure3. It is mainly used in power systems with a rated voltage of 12kV, such as substations and power plants, to switch rated current and short - circuit current, and can also be used as a tie - in circuit breaker and for switching capacitor banks3. With an in - built current transformer for measurement and protection, it is an ideal upgrade product for circuit breakers3.

It is suitable for outdoor three - phase AC power distribution systems with a rated voltage of 12 kV (the 40.5 in the model might be a related parameter or an error in some cases, as the common rated voltage for this type is 12 kV), a rated current of 630 A, and a rated frequency of 50 Hz. It is used to switch and close power distribution lines under load, and can also be used to switch and close no - load lines and no - load transformers. This load switch can be used in the power, metallurgy, mining, chemical industry, and other departments' power transmission and distribution systems to control circuits, and is also suitable for places with frequent operations.

The GN19 high - voltage indoor disconnector switch is a switching device used in high - voltage electrical equipment. It is mainly used to reliably isolate electrical equipment from the live part during power - off maintenance and other situations to ensure the safety of maintenance personnel and the normal maintenance of equipment. It is usually installed in indoor high - voltage switchgear cabinets or substations and is suitable for AC power systems with a rated voltage of 3 - 35 kV and a frequency of 50 Hz.

The 40.5 - kV 250 - A outdoor pole - mounted disconnect switch is a key electrical device used in outdoor high - voltage power distribution systems. It is mainly installed on poles and is designed to isolate electrical circuits in the power system under normal or maintenance conditions. This switch plays a crucial role in ensuring the safety and reliability of power supply by allowing for the convenient disconnection and connection of power lines when necessary.

The JDZ - 10 is a type of single - phase voltage transformer widely used in the Chinese power system. It is designed to accurately measure and transform high - voltage electrical signals into low - voltage signals that can be safely used by measurement and protection devices. These transformers play a crucial role in power distribution networks, substations, and various electrical equipment monitoring systems.
