VS1-40.5T High Voltage VCB Indoor Vacuum Circuit Breaker 40.5 KV

VS1-40.5T Type Indoor High Voltage Vacuum Circuit Breaker electrical equipment supplies

Product Introduction

-40.5 (modular type) indoor vacuum circuit breaker is suitable for indoor high voltage equipment with rated voltage of 40.5kV and three-phase AC 50Hz. It can be used as industrial and mining enterprises, power plants and substations as load current, overload current and short circuit. For current use, it is suitable for frequent operation.

Structure Features

1. Reliable modular spring operating mechanism: the layout of the spring operating mechanism is up-down style, which has the function of manual storing energy and electric storing energy; Small size, good overall stiffness, and performance

2. Sleeve structure(VS1-40.5): The vacuum extinguishing chamber of the main circuit is inside the closed insulating drum; The material of the insulating drum is epoxy resin which has reliable mechanical and electrical properties. Using advanced APG process molding, the insulating drum has the role of support and interphase and relative insulation effect

3. Encapsulated pole structure(VS1-40.5E): The conductive circuit adopts solid encapsulation pole; Using advanced APG process molding, put the vacuum interrupter and other parts (for primary circuit ) solid encapsulated with epoxy material, make the main circuit module. With inside and outside double skirt design, the pole has features such as large creepage distance, high mechanical strength, high part accuracy, fewer parts, no secondary adjustments, and a small lapped surface

4. Standard on-off function module: Modular design spring mechanism, which includes two functional modules: closing and opening; It has the characteristics of convenient maintenance, quick replacement, and short maintenance time; No readjustment for the entire circuit breaker’s operating mechanism after replacing the closing and breaking module, which can reduce maintenance work

5. Better handcart interchangeability and adaptability, installation size and ZN85, VD4, and other products; Strong breaking ability, long service life

Normal service condition

1. Ambient temperature: -15℃-+40℃, the average temperature is not more than 35℃ in 24 hours
2. Height above sea level:≤1000m;
3. Relative humidity: the average humidity of a day should be no more than 95%; the average humidity of a month should be no more than 90%;
4. Saturated vapor pressure: the average pressure of a day should be no more than 2. 2kPa, the average humidity of a month should be no more than l.8kPa;
5. Environmental conditions: It should be installed in places without dust, smoke, chemical erosion, combustible gas and saline fume pollution.
