Abstract
The utility model provides a vacuum circuit breaker, comprising an AC power supply, and a vacuum circuit breaker unit, a current limiting resistor, a current transformer and a zero sequence current transformer which are connected with the AC power supply in sequence. The vacuum circuit breaker is connected with a controller; the current limiting resistor, the current transformer and the zero sequence current transformer are all connected with a driving unit protector; the driving unit protector is connected with an electric thruster through a relay; and the AC power supply is a 1140 V or 3300 V AC power supply. The controller is a PLC or DSP control system. The driving unit protector is connected with a transformer. The vacuum circuit breaker is a convenient and reliable vacuum circuit breaker unit with strong interchangeability, the electric thruster achieves the function of an electric isolation switch, according to a remote signal, the PLC or DSP control system controls the electric thruster to push the breaker unit out integrally after the breaker is off, a conductive plug is off, and an electric isolation function is realized.
Description
Technical field
The utility model relates to a kind of actuator unit for mining electric product, especially relates to a kind of vacuum circuit-breaker as power supply unit under coal mine unit.
Background technology
The circuit breaker device core of domestic production at present, without electronic isolation disjunction mechanism, need disjunction manually.After circuit breaker damages, need integral body to be changed, comparatively heavy, can't quick-replaceable, interchangeability is poor.
Summary of the invention
The utility model provides a kind of Novel vacuum circuit breaker that can solve the problem and shortage of prior art
Vacuum circuit-breaker of the present utility model, it is characterized in that: comprise that AC power and described AC power are connected with vacuum circuit-breaker unit, current-limiting resistor, current transformer, zero sequence current mutual inductor in turn, described vacuum circuit-breaker unit is connected with controller, and described current-limiting resistor, described current transformer, described zero sequence current mutual inductor all are connected with the driver element protector; Described driver element protector is connected with electronic thruster by relay; Described AC power is 1140V or 3300V AC power.
Wherein, described controller is PLC or DSP control system.Described driver element protector is connected with transformer.
Vacuum circuit-breaker of the present utility model adopts the vacuum circuit-breaker unit, electronic thruster combines, and is a kind of convenient and reliable, the vacuum circuit-breaker unit that interchangeability is strong; Electronic thruster can be realized the function of electric isolating switch simultaneously; PLC or DSP control system can after circuit breaker disconnects, be controlled electronic thruster by the whole extrapolation of breaker unit according to distant signal, make conductive plug separately, realize the function of electronic isolation.
