Description
Technical field:
The present invention relates to a kind of fast electromotor driving low-voltage breaker, present technique belongs to the low voltage electrical apparatus technology field.
Background technology:
So far the argumentation and the low-voltage circuit breaker product of a large amount of relevant low-voltage circuit breakers all have the complicated mechanical operating mechanism, as DW series, CW series universal low-voltage circuit breaker product, CM serial plastic shell type circuit breaker and sliding Yuqin the 2nd phase of " low-voltage electrical apparatus " calendar year 2001 " AUTOCAD the moulded case circuit breaker Analysis of Parameters with design in application " the relevant universal low-voltage circuit breaker of a literary composition or the like, moulded case circuit breaker all adopts the complicated mechanical operating mechanism, therefore, there is mechanism's complexity, reliability is low, disjunction is long operate time, breaking capacity is low, shortcomings such as performance index difference.
Summary of the invention:
The objective of the invention is to provide a kind of fast electromotor driving low-voltage breaker, and this device not only helps the quick connection of three-phase contact system contact and cut-offs circuit, and simple structure, and is reliable, controls the automaticity height.
The object of the present invention is achieved like this: it comprises power supply, operation and fault-signal collection and treatment circuit, circuit for controlling motor, fast driving motor, no mechanical operating mechanism rotary type three-phase switch contacts, it is characterized in that: power supply joins with the power input of operation and fault-signal collection and treatment circuit, circuit for controlling motor, fast driving motor respectively; The operation and the output of fault-signal collection and treatment circuit and the input of circuit for controlling motor join, the output of circuit for controlling motor is connected to the fast driving motor, coaxial the joining of driving shaft of the output shaft of fast driving motor power mechanism and no mechanical operating mechanism rotary type three-phase switch contacts, the contact that drives no mechanical operating mechanism rotary type three-phase switch contacts is connected fast and is cut-off.
When operation and fault-signal collection and treatment circuit collects switching signal after output offers circuit for controlling motor with control signal, electric machine control system drives the fast driving motor immediately, the contact of the nothing machinery operating mechanism rotary type three-phase switch contacts that the fast driving driven by motor is coaxial is connected circuit, when operation and fault-signal collection and treatment circuit collect normal disjunction or fault-signal after output offers circuit for controlling motor with control signal, circuit for controlling motor drives the fast driving motor immediately, the contact of the nothing machinery operating mechanism rotary type three-phase switch contacts that the fast driving driven by motor is coaxial cut-offs circuit
The present invention connects and the quick-speed turning on-off circuit by the contact that the fast driving motor direct-drive does not have mechanical operating mechanism rotary type three-phase switch contacts, not only improved the breaking capacity of circuit breaker, improved the circuit breaker reliability of operation, reduce requirement to circuit and load dynamic thermal stability, and, also have characteristics such as simple in structure, precise control, performance index height, reliability height because fast electromotor driving low-voltage breaker does not have the complicated mechanical operating mechanism.
