Description
Technical field
The utility model belongs to low voltage electrical apparatus technology field, specifically just relates to a kind of breaker closing actuator, can improve the reliability of breaker closing.
Background technology
Circuit breaker is divided into primary cut-out and low-voltage circuit breaker by its scope of application.Low-voltage circuit breaker, also known as automatic switch, is commonly called as " air switch " and also refers to low-voltage circuit breaker, and it is a kind of existing hand switch effect, automatically can carry out again decompression, under-voltage, overload and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc.; can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they; its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.; and generally do not need to change parts after disjunction fault current, obtain a wide range of applications.
As shown in Figure 1, on present market, the making electromagnet of universal breaker closing execution architecture is fixed on above operating mechanism, and operating mechanism combined floodgate lever has a cantilever, and making electromagnet iron core is positioned at the top of operating mechanism combined floodgate lever cantilever; When needing to carry out operating mechanism combined floodgate, making electromagnet iron core is got, the aircraft frame of actuating procedure mechanism, and then the cantilever promoted on operating mechanism combined floodgate semiaxis makes semiaxis rotate, thus makes mechanism carry out closing operation.But existing this omnipotent breaker closing operation apparatus parts quantity is more, and cause traditional breaker switching-on operation device volume huge, transmission stability is unreliable.
Utility model content
The purpose of this utility model is exactly more for above-mentioned existing breaker closing actuator part, the technological deficiency of Movement transmit complexity, a kind of breaker closing actuator is provided, optimizes the structure of breaking-closing operating device, improve the reliability of breaking-closing operating device.
Technical scheme
According to above-mentioned technical purpose, design a kind of breaker closing actuator, it comprises circuit breaker operation mechanism and closing electromagnets, closing electromagnets is installed in circuit breaker operation mechanism, it is characterized in that: the combined floodgate of described closing electromagnets moves the combined floodgate bracket end face that iron core control end stretches out self, stretch out combined floodgate support one end and be connected with rotating close brake lever rod, rotating close brake lever rod is contained on combined floodgate lever shaft can wrap the rotation of brake lever rod axle, combined floodgate lever shaft two ends are contained on operating mechanism side plate, the left side of rotating close brake lever rod is pressed in aircraft frame right-hand member upper surface, aircraft frame right-hand member can be made in rotating close brake lever rod rotation process to move downward, aircraft frame right-hand member moves downward in process the combined floodgate boss that can touch on combined floodgate semiaxis makes combined floodgate semiaxis rotating band move circuit breaker operation mechanism combined floodgate.
Further, described aircraft frame is contained in aircraft frame installation shaft, and by spring reset, aircraft frame installation shaft is installed on circuit breaker operation mechanism side plate.
Beneficial effect
The breaker closing actuator that the utility model provides, closed electromagnetic iron level is placed in above operating mechanism, closing electromagnets iron core get direction and operating mechanism combined floodgate semiaxis rotates the direction of separating brake not in same plane, whole mechanism simplifying Movement transmit, reduce the volume of breaker closing actuator, improve the reliability of sub-switching operation.
