Shanghai Huanniu will introduce the basic characteristics of the four commonly used voltage regulators. Without saying a lot, let's get to the topic.
First, fully automatic compensation power regulator
① Structure: The motor drives the carbon brush to slide between the windings of the self-propelled transformer to directly adjust the output voltage or adjust the output voltage through a compensation transformer
② Performance: strong load capacity, high work efficiency, small waveform distortion, strong anti-interference ability of the power supply itself
③Applications: industrial, agricultural, transportation, post and telecommunications, military, railway, scientific research culture, metal processing equipment, production lines, construction and rental engineering equipment, elevators, equipment, embroidery and textile equipment, air conditioning, radio and television, and household, lighting and other fields Wide application.
Second, AC purification regulator
① Structure: The method of combining sine wave energy distribution and filter is adopted, and the output voltage is adjusted by adjusting the conduction angle of the thyristor in the primary circuit
② Performance: high voltage accuracy ≤ ± 1%, fast response time ≤40ms, with sharp pulse filtering effect
③Application: Use in precision electronic equipment, equipment, computer room, laboratory, product aging and testing.
Third, the parameter regulator
① Structure: Use the saturation characteristics of the iron core material to highlight the stability of the output voltage
② Performance: high work efficiency, strong overload capacity, automatic protection, simple structure, large voltage stabilization range, and strong anti-interference ability
③Applications: in related computer products, monitoring systems, program control systems, automatic test equipment, radio and television equipment, post and telecommunications equipment, automatic plug-in machines, production lines, printing equipment, plastic injection equipment, ATMs, SMT equipment, scientific research experiments, etc. The field has a wide range of applications.
Fourth, magnetically amplified AC voltage regulator
① Structure: The magnetic resistance of the magnetic amplification transformer connected in series in the primary circuit of the autotransformer is used to stabilize the output voltage.
② Performance: high voltage stabilization accuracy and fast response time
③Applications: Precision electronics, equipment, computer rooms, laboratories, product aging and testing industries have a wide range of applications.
Common failures of high-power compensation regulators: Phenomenon: Failure to start
Whether the phase sequence of the input power line has been changed 2. The phase sequence of the input power line has been changed. The phase sequence protection circuit is faulty. 3. The open state at the emergency stop button:
Replace the phase sequence of the input line 2. Short the JO contact on the circuit board 3. Reset the emergency stop button DA Fault phenomenon: Manual control mode cannot be started, and the reason for the failure of the voltage regulation function is as follows:
The limit switch fails or the limit switch connection line falls off 2. The lift and depressurization buttons fail and the contact is not good 3. The motor power line is not in good contact 4. The motor is broken 5. The brush plate is stuck 6. The drive chain is disconnected or disconnected Exclusion method 2:
Reset the emergency stop button DA 2. Replace the button 3. Connect the power cord 4. Replace the motor 5. Repair the brush plate 6. Repair the chain With the popularity of more and more electrical appliances, so is our electricity bill. Increasingly, there is also a lot of wasted electricity costs, so high technology has made it possible and effective to save electricity. So, for everyone, I am no stranger to energy saving, so energy saving has become a trend.
