The mounting inclination angle degree of described insulating part is 45 degree.
Described operating mechanism is the operating mechanism without connecting rod.
Be filled with the high pure nitrogen of zero gauge pressure in the described casing.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art has following advantage and good effect:
Product of the present utility model has been owing to adopted Modular Structure Design, and good looking appearance, volume are little, weight only is about 80% of like product; Spring mechanism is designed to improve reliability without connecting type of drive; Replace the sulfur hexafluoride gas that can produce greenhouse effect, environment-protecting clean with high pure nitrogen; Built-in one group of Integral three-phase zero sequence current mutual inductor and one group of three-phase alone type current transformer can be realized manually, electronic, on the spot and remote operation, satisfy the various requirement of intelligent power network.
The utility model is different from traditional breaker mechanism external hanging type, the utility model all is placed in whole circuit breaker in the seal case of the high pure nitrogen that is filled with zero gauge pressure, can not only effectively prevent the generation of condensation phenomenon, effectively stop insulating capacity and descended and the parts corrosion, and met the environmental protection concept that advocate in current manufacturing field fully.Operating mechanism adopts built-in design concept, has broken away from the constraint of traditional concept, General Promotion the product reliability of operation, especially the reply outdoor adverse weather condition defensive ability/resistance ability greatly improve.
The utility model is under the prerequisite that does not change box shape size and general structure: a. can select spring operating mechanism, also can match permanent magnet mechanism simple in structure, that parts are few, reliability is high according to customer requirements.The exchange of different operating mechanisms can both guarantee the indices of circuit breaker.B. require and configuration according to difference, it can be expanded to automatic circuit, sectionalizer and on-load switch etc., be fit to various application conditions and environment, extension property is good.
