40.5kV HV SF6 circuit breaker

Nààɗàɓi aiki:

LW36-40.5 outdoor self-energy HV AC SF6 circuit breaker shine ne aiki na gida tare da karshe tsawon sanyi mai tsarki da yake da 3000m, tsarin hawa da yake da -40℃, tsohon zafi da yake da Class IV, da kuma AC 50Hz/60Hz da tsari mai tsarki ta 40.5kV, yana da kyau don kontrol da ingancin hanyar tsawon sanyi a mazauna, mazaunuka, da kuma masana'antu da takamakona. Zan iya amfani a matsayin circuit breaker na gabashin hanyar.

Abubuwa masu muhimmanci:

LW36-40.5 self-energy HV SF6 circuit breaker ana samun hot-expansion plus auxiliary pressure gas self-energy arc extinguishing technology mai yawa da sabbin spring actuating mechanism, tana da abubuwan da suka biyo, kamar tsari mai yawa, kudin gwamnati mai yawa, tsari da kuma mekanikin mai yawa, tsari mai yawa, da kuma kyautar mai yawa. Abubuwan da suka biyo sun hada da:

• Tsari mai yawa: tsari mai yawa ta 2500A/4000A da kuma tsari mai yawa ta short circuit breaking current 31.5KA/40KA/50KA, yana da kyau don hanyar na gaba da karamin tsawon sanyi mai yawa.

• Tsari mai yawa:

Kyakkyawan hanyar na gaba da karamin tsawon sanyi mai yawa da kuma kyakkyawan hanyar na gaba da karamin cable charging breaking ability 50/60Hz dual-frequency C2, back-to-back capacitor bank breaking ability 50/60Hz dual-frequency C2, bane da re-breakdown;

Kyakkyawan hanyar na gaba da karamin tsawon sanyi mai yawa;, yana da kyau don iyaka da tsari mai yawa ta 3000m ko Class lV pollution.

• Tsari mai yawa na actuating mechanism:

Kudin gwamnati: hanyar na gaba da karamin tsawon sanyi 10000 times bane da lafiya; zai iya tabbatar da talabinta masu amfani a cikin hanyar na gaba da karamin tsawon sanyi mai yawa da kudin gwamnati mai yawa.

Sabbin spring actuating mechanism ana da koyarwa daban-daban; frame mai yawa mai cast aluminum da kuma brake separating and closing spring; da kuma centralized arrangement is adopted for the buffer, compact structure, reliable operation, low noise, and convenient maintenance; yana da kyau don hanyar na gaba da karamin tsawon sanyi mai yawa.

• Duk wata da ake fito a kan al ana da stainless steel materials ko hot-galvanized on the surface for high corrosion resistance.

• Tsohon hanyar na gaba da karamin tsawon sanyi mai yawa tana tabbatar da leakage rates≤0.5%.

• Four internally attached current mutual inductors for every phase can be installed on the circuit breaker. Microcrystal alloy and high permeability material are adopted for internally attached current mutual inductors. The accuracy of 200A and above current mutual inductors can reach up to Level 0.2 or 0.2S. Reliable electrical screening design is adopted for the cable coils of internally attached current mutual inductors to improve the electric field distribution of the mutual inductors and promote the internal insulation of the product. it can withstand 120kv and 5min working frequency withstand voltage test and the internal insulation is not interfered by the short circuit breaking working conditions, which makes it safe and reliable.

Abubuwan masu tsari mai yawa:

Bayanin order:

• Model and format of the circuit breaker.

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

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

• Rated control circuit electrical parameters (power-storage electromotor rated volage and brake separating and closing cable coil rated voltage).

• 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.

Power Transmission and Distribution:

• Power Transmission and Distribution: In high-voltage and ultra-high-voltage transmission lines, tank-type circuit breakers are used to control and protect the transmission of electricity. They can connect and disconnect circuits during normal operation and quickly interrupt fault currents when faults occur, ensuring the stable operation of the power system.

Substations:

• Substations: As one of the core devices in substations, tank-type circuit breakers work in conjunction with other electrical equipment to control and protect busbars, incoming and outgoing lines at various voltage levels within the substation. This ensures the safe and reliable distribution and conversion of electrical energy.

Industrial Power Supply:

• Industrial Power Supply: In the power supply systems of large industrial and mining enterprises, tank-type circuit breakers can be used to protect important electrical equipment and production lines, preventing power outages caused by short-circuit faults and other issues. This enhances the continuity and stability of production.
