Description
Technical field
The utility model relates to a kind of spring actuating mechanism of vacuum circuit-breaker.
Background technology
In recent years, on the basis that the vacuum interrupter connecting-disconnecting function improves constantly, the circuit breaker manufacturing process is constantly perfect, the circuit breaker theoretical research deepens continuously, the trend of oriented integrated, standardization of middle pressure vacuum circuit-breaker and miniaturization development.At present, the version of middle pressure vacuum circuit-breaker operating mechanism shows as:
1. the distribution mode of functional unit blockization, parts are distributed on the framework of circuit breaker by energy-storage module, combined floodgate module, separating brake module, state indicating module, the location of breaker body is the location to several functional modules, make that assembling, the maintenance of circuit breaker are extremely convenient, but its mechanism's complexity, profile are bigger, bring all inconvenience to processing, also improved product cost relatively;
2. the parts dispersed placement is on circuit breaker frame, and the characteristics of operating mechanism are that the position is accurate, but its parts are many, assembling maintenance inconvenient, and the relative raising that has also brought processing cost for the positional precision that guarantees parts;
3. the independent operating mechanism of installing is promptly split type, every mechanical property of circuit breaker must be debugged after installing on the switch cubicle, complex structure in addition, it is many to connect rod member, therefore the relative positional accuracy extreme difference of operating mechanism and breaker body makes the registration property instability of mechanism's output and drive system.
This class operating mechanism is a kind of to be special-purpose operating mechanism, and the corresponding a kind of circuit breaker of promptly a kind of mechanism brings great inconvenience for the mass of production and the generalization of product; Another kind of is the diverse location that operating mechanism and breaker body are loaded on switch cubicle, and volume is bigger, and compact inadequately, this two classes mechanism all can not realize the standardization of mechanism, brings all inconvenience for assembling, debugging, maintenance.
