ZW39-40.5 Outdoor Vacuum Circuit Breaker

Overview:

ZW39-40.5 Outdoor Vacuum Circuit Breaker is suitable for AC，rated voltage 40.5KV, rated frequency 50HZ three-phase power system.

The ZW39-40.5 Outdoor Vacuum Circuit Breaker can be operated frequently and can also be used as a contact circuit breaker. The product can adapt to the environmental requirements of 3000M above sea level, and the circuit breaker can be built-in or external transformers.

Structure: 

ZW39-40.5 Outdoor Vacuum Circuit Breaker can be equipped with 4 internal current transformers per phase, the inner current transformer core is made of microcrystalline alloy and high magnetic conductivity material, and the accuracy of 200A and above current transformers can reach 0.2 and 0.2S. 

The contact material of the vacuum interrupter is preferred, so that the small current breaking and shutdown value is below 4A on average, effectively suppressing the operating overvoltage. Using reliable performance CT10A improved mechanism, can be operated frequently, service life of the device up to 10,000 times. 

ZW39-40.5 Outdoor Vacuum Circuit Breaker has strong breaking ability, and the short circuit current of opening and breaking is 31.5kA up to 30 times.

Advantage:

1. The Vacuum arc extinguishing, strong breaking ability, long mechanical life;

2. Simple structure, no maintenance cycle is long;

3. Good insulation performance, strong anti-fouling ability, no fire and explosion hazard;

I4. t can be built-in or external two- or three-phase current transformer, with high measurement accuracy;

Built-in intelligent temperature and humidity controller to ensure the normal and reliable operation of the product in alpine areas;

5. The overall sealing design improvement of the shell can effectively prevent the adverse effects caused by bad weather such as sandstorms;

6. The product is a substitute product for less oil circuit breaker, more oil circuit breaker and sulfur hexafluoride circuit breaker;

Normal use conditions:

      a. Ambient temperature -40ºC ~+40ºC;

      b. Altitude not more than 3000m;

      c. Wind speed is not more than 34m/s;

      d. Daily temperature difference is not more than 25ºC;

      e. Daylight intensity is not more than 0.1w/cm;

      f. Monthly average relative humidity is not more than 90%;

      g. Seismic acceleration Horizontal not more than 0.2g, vertical not more than 0.1g;

      h. Ice thickness is not more than 10mm;

      i. The degree of air pollution does not exceed the IV. level in GB/T5582;
