ZW17-40.5 Outdoor Vacuum Circuit Breaker
Production Introduction
Overview:
ZW17-40.5 Outdoor Vacuum Circuit Breaker is independently developed by Shaanxi Huadian Electric Co., Ltd., suitable for three-phase AC rated frequency 50Hz, rated voltage of 40.5kV outdoor high voltage electrical equipment. It is used as a division of overload current, load current and short-circuit current, and is suitable for frequent operation.
The design performance meets the requirements of the CB1984-89 "AC High Voltage Circuit Breaker" standard. And to meet the IEC-56 "AC high voltage circuit breaker" International Electrotechnical Commission standard requirements and technical specifications.
Structure:
ZW17-40.5 Outdoor Vacuum Circuit Breaker structure is porcelain bottle pillar type; The upper porcelain bottle contains a vacuum extinguishing chamber, and the lower porcelain bottle is a pillar porcelain bottle. That is the reason why, it can meet the needs of frequent operations. And the product has the advantages of good sealing, anti-aging, high pressure resistance, no combustion, long service life without electrical appliances, convenient installation and maintenance. The product is mainly used for the control and protection of outdoor 40.5KV power supply system, and can also be applied to the normal breaking, closing and short circuit protection of urban and rural power grids and industrial and mining enterprises.
Advantage:
The product has the common points of vacuum circuit breakers，such as high mechanical life, long electrical life, and low maintenance;
The well-known brands at home and abroad vacuum arc extinguisher, safe and reliable, long life;
The latest insulation material, avoiding the shortcomings of inflation, oil filling and so on;
The current transformers have high precision, large capacity, multi-variable ratio, and multiple stages;
The use of CT19W-I spring mechanism, small operating power, long service life;
The appearance of the product is exquisite and beautiful;
A. The porcelain sleeve and flange are cast as one, with high strength, stability and reliability;
B. The addition of phase sequence caps avoids water leakage;
C. The base frame adopts hot-dip galvanized anti-corrosion process; The sealing effect of sealing plate and mechanism box is good
Normal use conditions:
1) Altitude: ≤1000m (special requirements will be negotiated separately);
2) Ambient temperature: -25°C~+40°C;
3) Wind pressure: not more than 700Pa
4) Earthquake intensity: not more than 8 degrees;
5) Pollution level: III. class, IV
6) Installation place: no fire and explosion hazard, no chemical corrosion and frequent violent vibration
