Description
Technical field
The present invention relates to breaker technical field, particularly breaker structure technical field specifically is meant a kind of vacuum arc extinguish chamber structure of indoor HVAC vacuum circuit breaker.
Background technology
Because the circuit breaker of prior art great majority adopt the vacuum interrupter of transverse magnetic field, because the arc burning of the vacuum interrupter of this kind structure is a beaming type, the arc extinguishing scarce capacity, the burn of the each arc extinguishing of arc control device is more serious, thereby have influence on the length in its life-span, the use cost height, and cause very big waste.
Therefore, press for the vacuum arc extinguish chamber structure of a kind of indoor HVAC vacuum circuit breaker of development, its arc burning evenly, the arc extinguishing ability is strong, burn is slight, long service life, thereby reduce use cost, economizes on resources.
Summary of the invention
The objective of the invention is to have overcome above-mentioned shortcoming of the prior art, a kind of vacuum arc extinguish chamber structure of indoor HVAC vacuum circuit breaker is provided, this vacuum arc extinguish chamber structure designs ingenious uniqueness, arc burning is even, the arc extinguishing ability is strong, burn is slight, long service life, thereby the reduction use cost economizes on resources.
To achieve these goals, the vacuum arc extinguish chamber structure of indoor HVAC vacuum circuit breaker of the present invention has following formation:
The vacuum arc extinguish chamber structure of this indoor HVAC vacuum circuit breaker is characterized in, the magnetic field of described vacuum arc extinguish chamber structure is longitudinal magnetic field.
Preferably, described vacuum arc extinguish chamber structure comprises shell, quiet end assembly, the moved end assembly, main shield cover and bellows, described main shield cover and described bellows are installed in the described shell, described shell comprises insulation shell, moved end cover plate and quiet end casing, described moved end cover plate and described quiet end casing are installed in the two ends of described insulation shell respectively, described quiet end assembly comprises static conductive rod and fixed contact, described fixed contact is arranged in described main shield cover, described static conductive rod one end connects described fixed contact, the other end is fixed in the described quiet end casing, described moved end assembly comprises moving conductive rod and moving contact, described moving contact is arranged in described main shield cover and contacts with described fixed contact, described moving conductive rod one end connects described moving contact, and the other end wears described bellows and passes described moved end cover plate.
