Background technique
According to the intelligentized demand of China's supply network, State Grid Corporation of China requires supply network intelligent.Therefore, it is necessary to End signal has tripping, closes a floodgate in the end effector of supply network --- miniature circuit breaker (or miniature circuit breaker) execution Function.Therefore the current development trend of miniature circuit breaker is threaded off automatically in addition to having traditional manual divide-shut brake and over-current and -load Outside function, it is also necessary to have the function of automatic divide-shut brake and reclosing, to realize long-range control;Intelligent electric meter is especially combined, It realizes arrearage automatic trip power-off, fills the function of expense automatic closing power transmission.
The important function of automatic reclosing: feeder line fault is the failure of " instantaneity " mostly, is switched off device in route After disconnecting rapidly, the dielectric level of fault point be can be self-healing, and failure also just disappears immediately.At this point, if the open circuit of disconnection Device closes again automatically namely automatic reclosing, it will be able to restore normal power supply.Automatic reclosing is capable of providing confession as a result, Electric reliability reduces number and the time of line outage;For breaker itself since mechanism is bad or protective relaying maloperation is made Caused mistrip can also play correction.
Present reclosing breaker is by the drive mechanism band in reclosing mechanism shell mostly when closing a floodgate Co-acting lever rotation on dynamic reclosing mechanism shell, and then breaker closing is driven by interlocking bar, lead to reclosing in this way Mechanism shell is equipped with the handle of protrusion, not easy to install since size is larger when connecting with other equipment.
Utility model content
In order to overcome the shortcomings of background technique, the utility model provides a kind of reclosing breaker for saving installation space, The reclosing mechanism shell for mainly solving present reclosing breaker is equipped with the handle of protrusion, connect with other equipment When the problem larger, not easy to install due to size.
The technical scheme adopted by the utility model is
A kind of reclosing breaker for saving installation space including the circuit breaker housing being connected and is overlapped brake mechanism shell Body, the circuit breaker housing include operation handle, it is characterised in that: power source are equipped in the reclosing mechanism shell and by institute The driving member of power source drive is stated, described driving member one end, which is protruded into the circuit breaker housing, drives the operation handle rotation.
Escape groove is equipped at the top of the reclosing mechanism shell.
The driving member drives the operation handle to rotate by transmission mechanism.
The transmission mechanism is gear drive.
The power source is motor.
The motor is equipped with worm screw, and the driving member includes the worm gear engaged with the worm screw, and the worm gear bottom is set There is drive sleeve, the reclosing mechanism shell is equipped with through-hole, states and is equipped with shaft in circuit breaker housing, the drive sleeve bottom is worn It crosses the through-hole and protrudes into the circuit breaker housing and hingedly cooperate with the shaft.
The circuit breaker housing is connected by screw to the reclosing mechanism shell.
The gear drive machine includes the first gear and second gear being meshed, the first gear and the drive sleeve Peripheral outer wall engagement, the operation handle are equipped with the incomplete driving cog engaged with the second gear.
The beneficial effects of the utility model are: the utility model provides a kind of reclosing breaker for saving installation space, Its driving member protrudes into circuit breaker housing from reclosing mechanism shell directly drives the handle of breaker to act, and is being overlapped brake mechanism On be not required to setting co-acting lever, terminal with compact integral structure, save installation space.
