Product Description


7.2kv Single Phase Vacuum Contactor for Power Transformer or Generator
7.2kv Single Phase Vacuum Contactor for Power Transformer or Generator


 

KCC3-24kV series ac voltage vacuum contactor is this company should market demand and development of the new generation of products, can completely satisfy the latest requirements 20kV network. Through summarizing the use of user experience for many years, and use our latest design concept, make the product both appearance and performance, reliability and easy to use have greatly enhance maintenance. Welcome the user chooses to use.

Product features

l  The main circuit

l  Vacuum interrupters used domestic well-known manufacturers of products.

    Mature technology, reliable quality, good market reputation.

l  Main loop using epoxy automatic pressure gel (APG) once moldings cylindrical insulation structure, the good rigidity, insulating high strength, good resistance to filth sex.

l  By 630A current level face and conductive clip double move end connection, resistance, low temperature, little more reliable.

l  Conductive row beautiful and durable, have the coincidental or different ends to qualify for two way choice, user-friendly.

l  Electromagnetic system

l  Optional permanent magnet institutions or traditional electromagnetic institutions.

l  Similar products in a unique built-in high-capacity seal, greatly improving auxiliary switch the reliability of the auxiliary switch, the use of security.

l  Optimization action structure, reduce the coil start power and 

 

keep power, and low temperature, long life, the more reliable.

l  Dynamic bit break-brake limit position setting limit buffer, eliminate because break-brake rebound amplitude of excessive brings hidden dangers of accidents. Meanwhile auxiliary switch led also used buffer, reduce action wallop, improve reliability auxiliary switch.

l  Action structure

l  Spindle is used by self-aligning bearing, supporting flexible without card, and the structural dynamic hysteresis, axial channeling, improved action small performance and consistency.

l  The second movement end, steering mechanism to ensure vacuum tubes move conductive stem axial movement coaxial degrees. Reasonable action institutions, improve the performance and reliability of the contactor. Make three-phase synchronicity, bounce index than similar products.

l  Enhance the main contactor contact pressure and improve the performance and movement characteristics. Indexes were superior to the similar products.

l  Mechanical keep device self-contained, reasonable structure, using more reliable.

l  Convenient usage and maintenance

l  Control circuit terminals have function marks, prevent wiring errors. According to user needs, will terminals installed in front or back of the machine, convenient connection. Auxiliary contacts quantity can use requirements combination.
