- 2. ++++General Vacuum contactor usesvacuum interrupter to extinguish arc to frequently connect and cut off normal working current. It is usually used for 6-40.5kV system AC motor in long distance connection and disconnection. ++++Application FVC series of Medium voltage vacuum AC contactors are widely used in coal, power, metallurgy and textile. High building and other industry departments. Medium voltage vacuum AC contactor is suitable for communication: 50-60HZ. rated voltage: 7.2kV/12kV/13.8Kv/15kV/24Kv rated current 63 to 630A feed network for long distance connection and Open circuit, and frequent starting and stopping the use of AC motor. It is especially suitable for assembling with all kinds of protective devices to form flameproof electromagnetic starter. ++++Product Feature: • Main circuit The vacuum switch tube uses products from well-known domestic manufacturers. The technology is mature, the quality is reliable, and the market reputation is good. The current rating of 630A adopts the double-acting connection of the end face and the conductive clip, which has small resistance, low temperature rise, and more reliable. The conductive row is beautiful, the cross-sectional area is better than that of similar products, and a reinforcing plate is installed at the upper end of the fixed-end conductive row to strengthen the connection strength between the copper row and the vacuum tube and prevent the damage caused by copper row deformation. • Electromagnetic system It adopts a closed structure and is equipped with a heat dissipation window to become a structurally complete electrical product. It fully satisfies the requirements for temperature rise and the like, and it can prevent the ingestion of dust and ferromagnetic substances and is safe to use. It is the unique structure of similar products. Optimize the structure of the operation, reduce the start-up power of the coil and maintain the power, so the temperature rise is low, the life is long, and it is more reliable. Set the limit buffer in the limit position of the iron breaker to eliminate the hidden accidents caused by the excessive amplitude of the rebound. At the same time, the auxiliary switch starter also uses buffer to reduce the impact force and improve the reliability of the auxiliary switch. • Operation Mechanism The shaft supports are flexible, the force is not stuck, and the axial movement is small, improving the performance and consistency. Reasonable operating mechanism to ensure that the vacuum tube moves the axial direction of the conductive rod. Improved contactor performance and reliability. Makes the same three-step, spring-jumping index better than similar products. Increases the contact pressure of the main contact, improving electrical performance and operating characteristics. The indicators are better than similar products. The mechanical holding device is self-contained, structurally sound and more reliable to
- 3. 1 use. • Easy touse and maintain The secondary circuit wiring terminals have function flags, and the alignment lines are separated by a fixed color to prevent the connection error and facilitate the inspection of the wiring. According to the user's needs, the terminal can be mounted on the front or back of the machine. The number of auxiliary contacts can be combined according to the requirements. ++++Technical specification Specification unit Rated Voltage（Ur） kV 7.2kV 12kV Rated Current（Ie） A 160 250 400 630 Rated Making capacity（Im） kA 1.6 2.5 4 6.3 Rated breaking capacity（Ic） kA 1.28 2 3.2 5.04 Rated withstand overload current and time kA/s 2.4/1 3.75/1 6/1 9.45/1 Rated short-time withstand current（Ik） kA 1.6 2.5 4 6.3 Rated peak withstand current （Ip） kA 4 6.25 10 16 Rated short circuit duration（tk） s 4 insulat ion level power frequency withstand voltage Fracture kV 42 Interpha kV 42 Ground kV 42 lightning impulse withstand voltage (peak) Fracture kV 75 Interpha kV 75 Ground kV 75 Main circuit contact resistance μΩ ≤200 ≤200 ≤200 ≤150 Rated operating frequency Times/h 600 Mechanical locking operation frequency Times/h 6 0 Mechanical durability (mechanical life) Million times 100 (For mechanical locking models, the lock device needs to be replaced every 300,000 times) Electrical durability (electric life) AC3 Million times 25 (closing current 6Ie breaking current 1Ie) AC4 Million times 6 (closing current 6Ie breaking current 6Ie)
