Specific embodiment
As shown in figure 1,380V three-phase alternating currents electrical network is connected with main power circuit breaker Q F, it is in parallel after main power circuit breaker Q F Have on the three phase supply electric wire of industrial frequency AC catalyst KM1 and be parallel with 1~20 oil pumper motor 4.Drive in oil pumper Be in series between motor 4 and main power circuit breaker Q F converter 1 and frequency-changing AC catalyst KM2 (input of converter 1 with it is total The outfan connection of power circuit breaker QF, the outfan of converter 1 is connected with frequency-changing AC catalyst KM2), industrial frequency AC contact Device KM1 is connected in parallel with converter 1, frequency-changing AC catalyst KM2, and frequency-changing AC catalyst KM2 and frequency-changing AC connect Tentaculum KM2 is interlocked.Energy feedback unit 2 is serially connected with converter 1, multiple stage converter 1 and energy feedback unit 2 are connected in parallel on one Rise, the input of energy feedback unit 2 is connected with converter 1, outfan and main power circuit breaker Q F of energy feedback unit 2 Output connection.
Lightning protection device 3 is connected to the front end of converter 1, the rear end of main power circuit breaker Q F.
Energy feedback unit 2 can be by feedback energy feedback to electrical network, it is to avoid energy waste.Lightning protection device 3 breaks with main power The outfan connection of road device QF.
The output of frequency-changing AC catalyst KM2 and industrial frequency AC catalyst KM1 accesses thermorelay after cable parallel connection Input, thermorelay outfan connection pumping-unit motor.Balancing forward direction A.C. contactor and the contact of balancing Opposed crossing Connect balance adjustment of pumping unit motor after the parallel connection of device outfan.
This device has power frequency, frequency conversion, takes out three kinds of methods of operation when working.Frequency-changing AC catalyst KM2 disconnects, and power frequency is handed over It is power frequency mode of operation when stream catalyst KM1 is closed..Frequency-changing AC catalyst KM2 is closed, and industrial frequency AC catalyst KM1 disconnects When, it is variable frequency work pattern.
