Pamutot ng 72.5kV HV SF6

Pakilala ng Produkto：

Ang LW36-72.5 self-energy outdoor HV AC sulfur hexafluoride circuit breaker ay isang outdoor three-phase porcelain column electrical equipment na pangunahing ginagamit sa AC 50Hz o 60Hz, 72.5kV electricity systems sa mga rehiyon na napakalamig (para sa mga electric stations sa karaniwang rehiyon at -42'℃ extremely cold regions). Ang produktong ito ay maaaring madalas gamitin at gamitin bilang isang connection circuit breaker.

Pangunahing Katangian：

• Mataas na performance -matibay na rated circulating ability: matibay na short circuit breaking ability hanggang 5500A. 50kA.

• Mahabang serbisyo -electrical endurance: 50kAx21times; mechanical life: 10000 times.

• Matatag na pag-break performance.

•  Matatag na sealing performance; Taunang leakage ng SF6 gas ≤0.5%.

• Nagpapatupad ng mga requirement ng mahihirap na working environments -sustantila para sa Class IV polluted environments.

• Maraming anyo ng structure-karaniwang porcelain column type at handcart type.

Pangunahing Teknikal na Parametro:

Talaan ng Pagsusunod sa Pag-order :  

• Modelo at format ng circuit breaker.

• Rated electrical parameters (voltage, current, breaking current, etc).

• Working conditions for using (environment temperature, altitude, and environment pollution level).

• Rated control circuit electrical parameters (Rated voltage of energy-store motor and Rated voltage of opening, closing coil).

• Names and quantities of spare items needed, parts and special equipment and tools (to be otherwise ordered).

• The wire connecting direction of the primary upper terminal.

Paano Pumili ng Tama na Uri ng Circuit Breaker?

System Voltage：

• System Voltage: Tukuyin ang working voltage ng sistema at pumili ng isang circuit breaker na maaaring tanggihan ang voltage level. Ang high-voltage at ultra-high-voltage systems karaniwan ay gumagamit ng SF6 gas o oil-immersed circuit breakers.

System Current：

• System Current: I-consider ang maximum continuous current at short-circuit current ng sistema, at pumili ng isang circuit breaker na may sapat na rated current at short-circuit capacity.

Application Environment：

Outdoor Environment：

• Outdoor Environment: Kung ang circuit breaker ay i-install sa labas, i-consider ang kanyang performance sa pag-resist sa pollution, moisture, at windblown sand. Ang tank-type circuit breakers (tulad ng mga gumagamit ng SF6 gas o oil) ay karaniwang mas sustantila para sa outdoor environments.

Indoor Environment：

• Indoor Environment: Para sa indoor installations, maaaring piliin ang mga circuit breakers na mas maliit sa laki at mas madaling i-maintain, tulad ng vacuum circuit breakers.

Insulating and Arc-Quenching Medium：

SF6 Gas:

• SF6 Gas: Nagbibigay ng excellent insulating at arc-quenching performance, nagpapahiwatig nito na sustantila para sa high-voltage at ultra-high-voltage systems. Gayunpaman, ang environmental concerns at leakage issues ay kailangan na i-address.

Insulating Oil:

• Insulating Oil: Nagbibigay ng mabuting insulating at heat dissipation properties, ngunit nagdudulot ng fire risks at environmental pollution issues. Sustantila ito para sa mga application kung saan hindi mahigpit ang fire prevention requirements.

Vacuum:

• Vacuum: Sustantila para sa medium at low-voltage systems, nagbibigay ng matagal na buhay, mataas na reliability, at madaling i-maintain.
