The invention discloses a wind generating set variable pitch charger detecting platform which comprises a three-phase driving power source, a contact type voltage regulator, a super-capacitor set and a discharging resistor. The three-phase driving power source is connected with the input end of the contact type voltage regulator, the output end of the contact type voltage regulator is connected with a three-phase alternating current input cable, and the other end of the three-phase alternating current input cable is connected with the voltage input end of a charger. A main loop switch, a default phase testing switch, an alternating current voltmeter and an alternating current detecting unit are connected to the three-phase alternating current input cable. The input end of the super-capacitor set is connected with a two-phase direct current output cable, the other end of the two-phase direct current output cable is used for being connected with the direct current output end of the charger, and the two-phase direct current output cable is connected with a direct current voltmeter and a direct current detecting unit. The super-capacitor set is connected with the discharging resistor through a two-phase discharging loop cable, and the two-phase discharging loop cable is connected with a discharging switch. The performance of a maintained variable pitch charger can be comprehensively detected, the product maintaining quality is improved, and the wind generating set variable pitch charger detecting platform can also be used for detecting products to be delivered out of a factory.
Description
technical field [0001] The invention relates to the field of charger detection, in particular to a detection platform for a pitch charger of a wind power generating set. Background technique [0002] As an important core component of the wind turbine, the pitch system can control the position of the blade angle to ensure the safe operation of the wind turbine. The wind turbines are located at the end of the entire power grid, and the quality of the power grid is poor, resulting in a large number of failures of the pitch chargers. In order to save costs, the failed pitch chargers are now repaired and reused to improve the utilization of spare parts . However, how to test the performance of the pitch charger after repair, and whether the test results meet the requirements of the use parameters, will be an important indicator to measure whether the repaired product is qualified. [0003] At present, the existing maintenance detection technology for the failed pitch charger is...
