Hydraulic Breakers and Chisels

Tavrida Electric develops and manufactures drawout vacuum circuit breakers with lightest weight (only 72 kg) and the fastest opening time (only 12 ms*) VCBs on the market. The circuit breaker is maintenance free and guarantees long mechanical and electrical life. Draw out units are assembled to be easily integrated into existing switchgear designs. Complete with the rackin cassette, guidearms, tulip contacts and safety interlocks Tavrida Electric withdrawable vacuum circuit breakers are perfectly suited for drawout panels manufacturing. *Special configuration available with opening times of 12 ms and closing times of 24 ms.

Tavrida electric uses its own innovative technologies and experience accumulated during the years of fundamental investigations and applied research to manufacture a wide range of MV vacuum circuit breakers. Tavrida Electric cooperates with more than 300 switchgear manufacturers and retrofit solutions providers worldwide. Over many years of cooperation, Tavrida Electric VCBs have proved versatile and easytouse for both new and existing switchgear panel designs, as well as for retrofit solutions. They are the smallest and lightest solution on the market, work regardless of spatial orientation, hence are very easy to install even in the most complicated designs.

Tavrida Electric's circuit breakers are the perfect match for applications like transformers or generators with a neutral earthing, server rooms and point on wave switching. The circuit breakers weigh less than 14 kg, meaning they can be installed quickly and cost effectively in even the smallest of spaces.

Air insulated switching module incorporates a Tavrida Electric vacuum circuit breaker with a per phase actuator, housed in a corrosion resistant tank. Six main circuit bushings, made from UVstable polymer, are covered with silicone rubber bushing boots. Each bushing has builtin current and voltage sensors for protection, measurement and indication purposes. The outdoor switching module is equipped with six, high voltage bushings with embedded current and voltage sensors. Current sensing is performed by Rogowski coil sensors. Capacitive sensors are used for voltage measurement in all six bushings. Tavrida Electric manufactures small vacuum interrupters with extremely long mechanical and electrical lifespans. A specially designed axial magnetic field distribution provides even current density over the contact surface and significantly improves the vacuum's interrupting performance.

Continuous selfsupervision. Vacuum circuit breakers equipped with the CM16 control module continuously monitors control, switching modules, functional wiring and auxiliary power supply quality. CM16 eliminates the necessity of additional trip and close coils, charging mechanisms and all related wiring supervision. The whole trip and close circuit supervision comes in single package with any Tavrida Electric VCB. CM16 allows the user to forget about scheduled trip and close wiring inspections as in the event of malfunction corresponding notification will be sent to the operator using one of the inbuilt output relays and indicated by inbuilt in CM LEDs. Low power consumption. Vacuum circuit breakers equipped with the CM16 control module need less than 42 W in charging mode – just 10% of what the best alternatives available on the market need!

Tavrida Electric manufactures small, compact vacuum interrupters with an extraordinarily long mechanical and electrical lifespan. A specially designed axial magnetic field distribution provides an even current density over the contact surface, substantially improving the vacuum interrupting performance. Vacuum interrupter contacts have unique design, based on the mixture of copper and chromium metals and various dopants, to ensure long electrical life of contacts, low contacts resistance and chopping current. The patented, supercompact actuator design allows the circuit breaker to be installed directly underneath each pole. The design is optimal in terms of reliability, dimensions, weight and ease of installation. A spring charged by the magnetic actuator during the closing of the circuit breaker ensures main contacts pressure is maintained. The spring is integrated in the actuator and does not require any maintenance during the circuit breaker's lifetime.

Highest Reliability Tavrida Electric's circuit breakers offer unrivalled reliability. Unlike other circuit breakers, they continuously monitor all secondary circuits. In the unlikely event of a malfunction, the circuit breakers will accurately indicate it locally with LED and remotely via relay contacts. Service team can fix a malfunction before it leads to a problem. Fastest operation Tavrida Electric's circuit breakers are the fastest on the market with opening times of 12 ms or less and closing times of 24 ms or less*. There's no better way to minimize the risks to personnel or members of the public; minimize damage to switchgear and other network equipment; limit the fault's current level; or reconnect critical loads to an alternative power supply.

Tavrida Electric has revolutionised circuit breaker design by developing a new generation of circuit breakers and controls with exceptionally fast opening, closing and response times. Opening and closing times are as low as 12 and 24 ms, respectively. This enables Fast transfer switches with transfer times as fast as 2 cycles. Such quick operational times allows very sensitive loads to operate without interruption in case of a main power source loss. The fast transfer switch solution eliminates costly downtime, reduces production equipment stress, ensures quick return on investment. Arc flash mitigation with interruption in one period. That quick interruption time increases operational safety, reduces switchgear restoration time and loss of productivity, limits switchgear damage and repair costs. Fault current limiting solutions without operational losses capable to automatically reconnect power sources.
