ZW7-40.5/ZW7-35 outdoor column high voltage vacuum circuit breaker overview:

The structure of ZW7-40.5/ZW7-35 vacuum circuit breaker is porcelain pillar type. The upper porcelain bottle is an arc extinguishing chamber porcelain bottle, which is equipped with a vacuum interrupter. The lower porcelain bottle is a pillar porcelain column. The three-phase porcelain bottle is mounted on a structural box, and the arc extinguishing is performed. The movable end of the chamber is connected to the output shaft of the spring mechanism through the arm and the insulating rod. The spring mechanism and the circuit breaker coupling link are in a waterproof mechanism box. The product is mainly composed of a vacuum interrupter, a current transformer, a transmission mechanism and a spring operating mechanism.

ZW7-40.5/ZW7-35 vacuum circuit breaker features:

ZW7-40.5/ZW7-35 vacuum circuit breaker is mainly used for the control and protection of outdoor 35KV power transmission and transformation system. It is also suitable for the normal operation and short circuit protection of urban and rural distribution networks and industrial and mining enterprises. The overall structure of the product is a porcelain bottle pillar type; the upper porcelain bottle is filled with a vacuum arc extinguishing type, and the lower porcelain bottle is a pillar porcelain bottle. Suitable for places where frequent operations are required. It has the characteristics of good sealing, anti-aging, high pressure resistance, no burning, no explosion, long service life and convenient installation and maintenance.

1. Porcelain column structure, waterproof transmission box, new type of vacuum interrupter (with Shaanxi Baoguang vacuum bubble);

2, 2-3 current transformers, four coils per phase, according to user needs to choose to change;

3, can be equipped with CD10 electromagnetic mechanism or CT19 spring mechanism;

4. Good breaking performance, high reliability, long service life and small maintenance workload;

5. No oil, no gasification, economic and environmental protection;

6. After the external insulation is corrected, the altitude is now 2700mm.

ZW7-40.5C/ZW7-35C intelligent circuit breaker:

    ZW7C-40.5 intelligent circuit breaker series automatic sectionalizer cooperates with the power supply pre-stage switch to automatically open the circuit when the line is out of voltage or no power supply. It can memorize the faulty line, the number of fault currents, and complete After switching the number of times, the switchgear that automatically opens without voltage or power supply can automatically perform the breaking and the gate operation in the AC line according to the predetermined breaking sequence, and automatically reset or lock the high voltage after it. Switching device.

    It has overload and short circuit protection function, quick-break protection function, time-delay delay protection function, automatic reclosing function, and can also be equipped with lightning arrester or isolating switch according to user needs (ie circuit breaker and isolation switch combination). The power supply can be operated remotely and has CT and PT interfaces to meet telemetry requirements.
