The JCZ1 vacuum contactor is a type of vacuum contactor. It is suitable for three-phase indoor electrical systems with an alternating current of 50-60Hz, rated operating voltages of 3.6kV, 7.2kV, and 12kV, and rated operating currents ranging from 160A to 630A. It can directly or remotely operate electrical equipment such as motors, transformers, and capacitive loads frequently. Its main features include an integrated frame structure, with remarkable characteristics such as stable performance, reliable operation, compact structure, and small size, making it an ideal switching device for voltage classes of 3.6kV, 7.2kV, and 12kV.
1. Ambient temperature: The surrounding air temperature shall not exceed +40℃ and shall not be lower than -25℃;
2. Altitude: The altitude of the installation location shall not exceed 1000 meters;
3. Relative humidity: The daily average shall not exceed 95%, and the monthly and annual average shall not exceed 90%;
4. Working environment: Places free from rain and snow erosion, open flames, explosion hazards, chemical corrosion, and strong vibration;
5. Pollution level: Level Ⅲ
6. Installation conditions: The inclination angle between the installation plane and the horizontal plane shall not exceed 5°;
1. The integrated frame and insulators achieve insulation between the high-voltage circuit and the ground, as well as between phases.
2. The contactor is arranged vertically (upper and lower). The upper part mainly consists of a vacuum interrupter and incoming/outgoing line terminals, forming the main circuit system.
3. The lower part mainly consists of an electromagnetic mechanism, a mechanical latching mechanism (mechanical holding mode), a base plate, springs, and other structural components. Through electromagnetic attraction, an electromechanical system with a specific movement direction and distance is generated. 4. The electromechanical system is connected to the vacuum interrupter in the main circuit system via insulators, enabling programmed switching.
5. The vacuum interrupter is composed of static and dynamic contacts, bellows, a ceramic shell, and other components, all vacuum-sealed. Since the switching of the contacts occurs in a vacuum, it has excellent switching characteristics.
6. The control circuit has two types: electric holding and mechanical holding: a. Electric holding closing: The electromagnetic coil is energized, and the closing is completed by the closing coil; the holding is completed by the holding coil. Electric holding opening: The holding coil in the electromagnetic coil is de-energized, and the opening is completed by a spring. b. Mechanical holding closing: After the electromagnetic coil is energized for closing, it is de-energized, and the holding is completed by the mechanical latch. Mechanical holding opening: The tripping coil is energized, the mechanical latch is opened, and the opening is completed by a spring.
