Abstract
The invention relates to an anti-misoperation device of a circuit breaker electric operation mechanism (referred to as electric operator), which is used for preventing misoperation when a circuit breaker equipped with the electric operator is impacted and is characterized in that the anti-misoperation device of the electric operator comprises a mounting plate (1), a mounting block (2), a magnet (3), a iron sheet (4) and a sliding block (5). The mounting plate (1) is a mounting substrate of the electric operator and is fixed on the circuit breaker, the mounting block (2) is made of non-metallic materials and fixed on the mounting plate (1) through a screw, the magnet (3) is fixed on the mounting block (2) through the screw, the iron sheet (4) is fixed on the sliding block (5) through the screw, the sliding block (5) is one part of the electric operator, and the sliding block (5) drives the circuit breaker to carry out up and down (opening and closing) motion. When the circuit breaker is closed, the position of the iron sheet on the sliding block is just at the position which is attracted by the magnet. The magnet firmly attracts the iron sheet under the situation of strong impact, thereby preventing that the electric operator drives the circuit breaker to be impacted and further avoiding misoperation.
Description
Technical field
The present invention relates to a kind of false action-proof device of electric operating mechanism of circuit-breaker, belong to electrical technology field.
Background technology
Low-voltage circuit breaker is mainly born overload, the under voltage of distribution line and power consumption equipment, the usefulness of short-circuit protection.
Under normal circumstances, in low-voltage distribution system, circuit breaker closed or disconnect (but breaker operator electricity consumption behaviour) reaches the purpose of power supply, power failure and change-over circuit.Motor-operating mechanism is used for far distance automatic separating brake and combined floodgate circuit breaker as the external accessory of circuit breaker, is applicable to the place that automaticity is higher.
Electrical network occurs under the local abnormal conditions, and for example overload, decompression or under-voltage, short circuit etc. can automatically disconnect load from electrical network.Because these abnormal conditions will jeopardize operating personnel's the safety or the normal operation of equipment, even cause personal fatal accident or cause fire.
Because the needs of naval vessel operation promptly are that low-voltage circuit breaker is running in emergency circumstances, are not subjected to ectocine, as still being kept closed under the situations such as overload, short circuit, decompression, under-voltage, impact, holding circuit is powered continuously.
When circuit breaker when being subjected to thump, often under the effect of external force, closed circuit breaker generation misoperation is the situation of separating brake, this phenomenon never allows in some special places.
Summary of the invention
The object of the present invention is to provide a kind of false action-proof device of electric operating mechanism of circuit-breaker, this installs under the effect of certain direction external force, and electric operating mechanism of circuit-breaker misoperation can not take place.
For achieving the above object, technical scheme of the present invention is: this device comprises mounting panel, mounting blocks, magnet, iron plate and slide block; Mounting panel is the installation base plate of motor-operating mechanism, is fixed on the circuit breaker, and mounting blocks is that nonmetallic materials are made, be screwed on the motor-operating mechanism mounting panel, magnet by screw on mounting blocks; Iron plate is screwed on slide block, and slide block is the part of motor-operating mechanism, (closing branch) motion about being done by its drive circuit breaker.
Under normal circumstances, be in closing position, the position that the iron plate position is being held by magnet just on the slide block at circuit breaker.Under the situation of thump, magnet firmly holds iron plate, thereby prevents that the motor-operating mechanism slide block from driving circuit breaker and being hit and misoperation takes place.
During breaker open operation, the separating brake power that applies only need overcome magnet suction than usual and get final product, and can not influence the normal occlusion branch of circuit breaker.
Beneficial effect of the present invention: compared with prior art, when the circuit breaker of charged pneumatic operating mechanism when make position is subjected to thump, under the effect of certain direction external force, misoperation can not take place and still be kept closed in circuit breaker, satisfy the needs of naval vessel operation, had certain economic benefits.
Below in conjunction with drawings and Examples to the present invention's detailed explanation of making comparisons.
Description of drawings
Fig. 1 is the structural representation of electric operating mechanism of circuit-breaker false action-proof device of the present invention;
Fig. 2, Fig. 3 are the structural representation of the false action-proof device of circuit breaker of the present invention under normal circumstances.
Embodiment
With reference to Fig. 1, this is the structural representation of the false action-proof device of electric operating mechanism of circuit-breaker of the present invention.
As shown in the figure, this device comprises mounting panel 1, mounting blocks 2, magnet 3, iron plate 4 and slide block 5.Mounting panel 1 is the installation base plate of motor-operating mechanism, is fixed on the circuit breaker, and mounting blocks 2 is made for nonmetallic materials, is screwed on mounting panel 1, and magnet 3 is screwed on mounting blocks 2; Iron plate 4 is screwed on slide block 5, and slide block 5 is parts of motor-operating mechanism, (closing branch) motion about being done by its drive circuit breaker.Under normal circumstances, in the breaker closing position, the position that the iron plate position is being held by magnet just on the slide block.Under the situation of thump, magnet firmly holds iron plate, thereby prevents that the motor-operating mechanism slide block from driving circuit breaker and being hit and misoperation takes place.
With reference to Fig. 2, Fig. 3, this is the structural representation of the false action-proof device of circuit breaker of the present invention.After circuit breaker is loaded onto motor-operating mechanism, close the branch operation and can realize by the electronic and manual operation of motor-operating mechanism.
As shown in Figure 2, this figure is the cut-away view of motor-operating mechanism.When electronic, the motor-operating mechanism device is closed the instruction of (branch) lock, the driven by motor master gear, the revolution that obtains requiring by engagement between gear, make the certain position of cam rotation, drive slide block to combined floodgate or the motion of separating brake direction by locating shaft, and slide block drives the circuit breaker motion by handle, makes breaker closing or separating brake.Under normal circumstances, magnet and iron plate do not influence circuit breaker normal occlusion branch, have guaranteed the realization of circuit breaker defencive function.
As shown in Figure 3, this figure removes the cut-away view of seeing motor-operating mechanism behind the part such as mounting panel from bottom to top.In manual position, the branch that closes of motor-operating mechanism passes through manual drive manual link and then drives slide block to move to combined floodgate or separating brake direction, and slide block moves by handle drive circuit breaker, makes breaker closing or separating brake.Under normal circumstances, magnet and iron plate do not influence circuit breaker normal occlusion branch, have guaranteed the realization of circuit breaker defencive function.
Though the present invention describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the present invention; should understand and wherein can make variations and modifications and do not break away from the present invention in a broad sense; so be not as limitation of the invention; as long as in the connotation scope of type of the present invention, to the variation of above-described embodiment, the protection range that distortion all will fall into claim of the present invention.
