Abstract
The utility model discloses a hand-operated and automatic integration opening and closing apparatus for a residual-current operation breaker. The apparatus comprises a motor, a ratchet pawl device, a driving disk, a positioning bearing, a spring energy storage mechanism, a connection rod, a sliding block, a guide rod, a hand-operated handle, an apparatus frame and a breaker, wherein a rotation shaft of the motor is connected with the ratchet pawl device, and the driving disk is driven in a clockwise direction and connected with the connection rod and the sliding block. According to the utility model, a circumferential driving stroke is converted into a straight driving stroke, such that the hand-operated handle and the breaker handle are connected with the sliding block to achieve the hand-operated and automatic opening and closing functions; besides, the apparatus is fixedly mounted at an upper part of the breaker, and the driving disk is limited by the positioning bearing and the spring energy storage mechanism so as to achieve no-dead-region operation of the driving device, thereby providing an integrated opening and closing apparatus which is really compatible for automatic and hand operation.
Description
Technical field
This utility model relates to a kind of and the matching used multiduty panel switches of protective device for low voltage electric network.
Background technology
Domestic Distributing Network Automation degree improves constantly, and is more and more higher to duality and the reliability requirement of the combined floodgate of circuit breaker especially residual current action breaker or separating brake mode.At present, domestic most low-voltage electrical apparatus manufacturing enterprise is subjected to the restriction of breaker structure development, although most of circuit breaker has been realized automatic closing or separating brake by motor-operating mechanism, can't realize manual operation; The device that can realize two kinds of modes of operation is also arranged, but often need to be by other instrument, Shortcomings on user's processing safety and convenience.
Summary of the invention
in order to overcome this deficiency, the utility model provides a kind of residual current action breaker hand control and automation integral type to divide, closing device, this New operation device is installed at residual current action breaker top, remote operation control signal by circuit breaker realizes (electronic) circuit breaker automatically, when the low-voltage distribution wire circuit breaker need to overhaul or need to close a floodgate manually or during separating brake, but direct control circuit breaker and need not other any servicing unit or instruments, realize that really automatic (electronic) operating process of circuit breaker is connected with the accessible of manual operation flow process.
The technical scheme that the utility model adopts is:
A kind of residual current action breaker hand control and automation integral type is divided, closing device, formed by motor, click apparatus, driving-disc, location bearing, spring energy agency, connecting rod, slide block, guide rod, Manual operation handle, device frame, circuit breaker etc., motor transmission shaft is connected with click apparatus, and clockwise direction drives driving-disc and connects connecting rod and slide block; Utilize circumference to be converted into straight driving stroke, Manual operation handle is connected with slide block with circuit breaker handle realizes that hand control and automation divides, closing function, device is fixedly mounted on the top of circuit breaker by the device frame, by location bearing and spring energy agency, driving-disc is spacingly realized the drive unit operation without the dead band, really accomplish (electronic) automatically again can be manually compatible integral type switching off/on device.
1, the driving mechanism of device adopts the operating principle of click, has ensured the motion self-locking performance of mechanism, can effectively prevent the misoperation of circuit breaker.
2, by to combined floodgate, trip free, the separating brake of circuit breaker, detain again the abundant analysis of process, the linkage of design is realized that the circumference of motor drives and is converted to the required straight driving of circuit breaker action;
3, hand control and automation switching mode: the coordinating of the location bearing on the spring energy agency of device and driving mechanism, when motion, spring-loaded, driving mechanism can turn over the dead-centre position fast, do not have clutch to unite or disengaged mode, need not increase external aid yet, need not to change the compatibility that can realize hand control and automation operation, can not be stuck, safe and reliable, ensured the integraty completely of the mechanism of breaker closing or sub-switching operation.
The beneficial effects of the utility model are:
Configured the residual current action breaker of this device when circuit control needs, driven automatic operation system by remote control signal and realize closing a floodgate or separating brake.When the electronic control system of circuit breaker breaks down because of a variety of causes or overhauls circuit and need, directly manual operation has reduced the power failure that causes because of misoperation, has greatly improved the efficient of power grid operation, management.
