Background technology
As the continuous progressive power electric component of industrial technology is widely used in work China Democratic National Construction Association equipment, brought just to me It is sharp efficiently while, also to network system the harmonic pollution, traditional LC filters can be caused can not to be changed according to system load Effective strain is made, filter effect is bad, be susceptible to electric fault, APF active power filtering cabinets are specially administered in network system Harmonic wave.
The content of the invention
To solve the problems, such as prior art, the present invention provides a kind of low-voltage active filter cabinet, can solve the problem that traditional LC Filter can not make effective strain according to system load change, and filter effect is bad, is susceptible to the problem of electric fault.
To achieve the above object, the technical solution adopted by the present invention is:
A kind of low-voltage active filter cabinet, including current transformer, breaker, active power filtering module and touch screen controller, it is described Active power filtering module includes active filtration module one, active power filtering module two and active power filtering module three, and three are drawn from power supply Phase power line, current transformer is connected on the three-phase power line, is connected on the three-phase power line in front of current transformer Breaker, the output end of the breaker successively with active power filtering module one, active power filtering module two and active power filtering module three Input connection, the output end of the current transformer is connected with the output end of active power filtering module one, the active power filtering Module one, active power filtering module two and active power filtering module three are connected with each other, the touch screen controller and active power filtering module One connection.
Fuse one, fuse two and fuse three are connected between the breaker and active power filtering module one, it is described Series-connection power supplies indicator lamp one, power supply indicator two and power supply indicator three are distinguished on fuse one, fuse two and fuse three.
Arrester one, arrester two and arrester are parallel with the fuse one, fuse two and fuse three respectively Three, the arrester one, arrester two and the earth of arrester three.
The active power filtering module three connects scram button.
The active power filtering module one, active power filtering module two and active power filtering module three are grounded respectively.
Beneficial effects of the present invention:
The present invention timely and effectively can change the adjustment for responding by tracking system harmonic wave, in the metastable situation of system load The harmonic wave filtered in power network of lower energy 100%, while there is reactive-load compensation, the effect that imbalance is administered.
Filtration module mainly acts the harmonic wave filtered in power network in the present invention, while there is reactive-load compensation, what imbalance was administered Effect, is uniformly controlled by cabinet face controller, touch-screen display operation.
Active power filtering can once solve various power quality problems in power network in the present invention, cut modularized design property on probation By force, traditional LC filtering specific aim is thoroughly avoided single, and can not be with the load defect that adjust of change.Power electronics unit device Part more clean and effective, energy-conserving and environment-protective.
