Description
Technical field
The invention belongs to the power distribution automation equipment technical field, be specifically related to a kind of outdoor high-voltage permanent magnet type vacuum circuit breaker.
Background technology
Whole missions of circuit breaker, be the branch that is embodied in contact after all, close in the action, realize by operating mechanism and divide, close action, so the quality of the service behaviour of operating mechanism and quality, play a part very important the service behaviour and the reliability of circuit breaker.The operating mechanism of switchgear needs more machine components to form, and this is the cost height not only, and reliability is low, is directly proportional because the possibility that failure rate rises is a quantity with part.Operating mechanism at present commonly used has two kinds of spring mechanism and electromagnetic mechanisms.Spring operating mechanism is the spring that utilizes energy storage makes the circuit breaker action for power a operating mechanism.Spring energy-storage is normally finished by deceleration device by motor.Whole operating mechanism is broadly divided into spring energy-storage, keep and close a floodgate and combined floodgate is kept and four parts of separating brake.The advantage of spring operating mechanism is not need powerful DC power supply, and motor power (output) is little, AC/DC, suitable alternating current operation; Its shortcoming is the structure more complicated, number of spare parts many (being about 200), and require the machining accuracy height, and the manufacturing process complexity, the cost height, the reliability of mechanism is difficult for guaranteeing.The advantage of electromagnetic operating mechanism is simple in structure; number of spare parts few (being about 120); reliable operation; low cost of manufacture; but the power that its shortcoming is a closing coil to consume is too big, and the pressure of contact is less, adds the heaviness of mechanism; operate time is longer, and also needs the user to be equipped with expensive batteries etc. usually.
Patent documentation 200420079109.0 discloses a kind of Outdoor Permanent Magnet Mechanism Vacuum Circuit Breaker, comprises pole, base and operating mechanism: a) also comprise support, slide plate and pin; B) described operating mechanism is made up of tripping spring, motion main shaft and machine barrel, and described tripping spring one end is connected with base, and another free end is connected with the motion main shaft, and the machine barrel combination is fixed on the base, and cross-under campaign main shaft; C) described support is connected with insulated tension pole, which is provided with guide rail, slips on described guide rail after pin and slide plate one end are hinged, and the slide plate other end and motion main shaft are hinged.When mechanism need close a floodgate, the electric current of the logical certain orientation of coil, the coil of energising can produce magnetic field, therefore, armature is subjected to the action of a magnetic field that closes of coil current and permanent magnet generation, at this moment, armature is subjected to the magnetic field force that closes to the right, under the effect of this power, the motion main shaft that the armature drive is fixed together is to left movement, move to left with the motion main shaft on one side with the hinged slide plate of motion main shaft, around pin joint rotate on one side, make hinged and place the pin in the guide rail to move up with slide plate, the promotion support moves upward, and drive connected insulated tension pole and move upward, three-phase contact (moving contact) moves upward synchronously, up to moving, till fixed contact closes, realize closing a floodgate, and under the magnetic field force effect of permanent magnet, remain on closing position, and tripping spring is stretched, laid in the potential energy of return.
The shortcoming of this kind structure is that described support is connected with insulated tension pole, when closing a floodgate, the motion main shaft moves to left and is need be by slide plate hinged and place the pin in the guide rail to move up, also will promote support simultaneously moves upward, because be subjected to the restriction of the shape of support, support also will drive the motion main shaft and do certain displacement that makes progress when moving upward, cause the motion main shaft unbalance, be difficult to correctly work or be easy to take place misoperation in actual the use.
